I have a problem, but one with a twist. In 1979 I was flying our homebuilt Pitts S1 VH-SIE when training at Murray Bridge prior to the Australian Aerobatic Championships. None of the Pitts owners had starters fitted; they had been removed to lighten the aircraft. I checked my fuel with my dipstick. There was a quarter of a tank – ample I thought for a 15-minute aerobatic flight. One of the first manoeuvres was a vertical climb followed by a stall turn, but I was not as far as the stall turn when the engine quit. I got the nose down immediately, hoping that my speed would turn the engine over, but I was too low to gain sufficient speed to turn over the engine and I had to plan an emergency landing. I had been practising over the cross strip so I did a steep approach, turned onto finals and side-slipped down to a rather bumpy landing. I left my aircraft there and went into the clubhouse for a cup of coffee. After the coffee I returned to my Pitts with another AAC member and strapped myself in. The other member gave one pull and my engine fired. I took off and did one circuit to steady my nerves. This was a valuable lesson for other Pitts owners and for me. A quarter tank of fuel was unusable when vertical. I later fitted a header tank that only had about three litres of unusable fuel when vertical, but this was OK since it held about 12 litres in total.

The year also marked the longest period without a fatal airliner accident in modern aviation history. In 2011, the ASN recorded a total of 28 fatal airliner accidents, resulting in 507 fatalities and 14 on-ground fatalities. This number of fatalities is lower than the ten-year average of 764. The worst accident happened on 9 January 2011, when an Iran Air Boeing 727 crashed on approach to Orumiyeh, Iran, killing 77 people. The number of accidents involving passenger flights was relatively high, with 19 accidents as compared to the ten-year average of 16 accidents. Seven of 28 accident aircraft were operated by airlines on the European Union ‘black list’, as opposed to six of 29 in 2010. The E.U. added a total of nine airlines to the ‘black list’ and removed three airlines, after they achieved improved safety records. In 2011, Africa showed a continuing decline in accidents: 14 per cent of all fatal airliner accidents happened there. However, the continent only accounts for about three per cent of all world aircraft departures. Russia suffered a very bad year, with six fatal accidents. Electronic flight bag approval American Airlines is the first carrier to allow pilots to use iPad tablet computers for digital charts and manuals in all phases of flight. The airline will use the iPad on its Boeing 777s as a Class 1 electronic flight bag (EFB), described by the FAA as a ‘portable, commercial, off-the-shelf computing device that is not attached or mounted to the aircraft’. The approval covers a Class 1 EFB running Type A and Type B software applications for electronic manuals and charts. The FAA requires crew members to secure or stow Class 1 EFBs not attached or mounted to the aircraft during critical flight phases. Those with Type B software, including ‘dynamic, interactive applications’, may be used, but must be ‘secured and viewable during critical phases of flight and must not interfere with flight control movement’. American Airlines pilots secure the iPad to the forward chart holder with an FAA-approved securing mechanism. American has carried out 777 flight evaluations using digital manuals, gathering thousands of hours and test points in the process. American Airlines is not the only commercial carrier to use iPads as EFBs, a practice that has proliferated in business aviation. Last spring, Alaska Airlines started issuing iPads to 1,400 pilots to replace paper manuals, largely as a weight and fuel-saving measure. British Airways is also distributing iPads to 2,000 senior cabin crew for customer service applications. In Australia, Qantas is in a staged trial of EFB. CASA has also convened an EFB industry working group with representation from the major players. A draft CAAP will be released shortly for public comment. Cabri G2 Now available in Australia!

They won the gong for producing a DVD for airside and landside manual handlers, showing ground handling operations from the perspective of both ramp and passenger services. The DVD also shows ground staff performing their roles, highlights ways in which they can improve their manual handling techniques, and explains the risks staff expose themselves to by not following good manual handling techniques. Very few people engaged in general aviation are aware that they are eligible to join the RAAF Association. All you need is a keen interest in aviation. The DVD will be shown during the induction process for all new Queensland Airports staff, as well as helping to educate current staff about improved work practices and correct manual handling techniques. ‘Here at the northwestern Tasmania branch, for example, we hold monthly meetings for general business; several commemorative dinners are held yearly, as well as BBQs and bus tours. There is also the pleasure of socialising with people of similar interests,’ writes Derek Padgett, northwestern branch committee member. Associate membership allows partners to join, making it family friendly. And your area of aviation expertise may also be valuable for volunteer work with such groups as the air cadets.

The 2012 Australian & New Zealand Societies of Air Safety Investigators (A/NZSASI) seminar will be held in Sydney at the Mercure Hotel, George Street, from 1–3 June. ‘We have the role of everything regarding safety, and it’s important to know that, because previously it was also Eurocontrol, which was taking care of safety, of ATM. Now this task has been transferred to EASA … we now have under our umbrella all domains of aviation regarding safety.’ Goudou went on to explain that the time frame for implementing EASA’s air traffic management responsibilities, would be the end of 2012, at which stage the agency ‘will start working on real issues, because by then we will have all the regulatory framework in place’. The seminar will include wide-ranging presentations and papers covering contemporary air safety investigation and air safety issues. This year’s seminar promises to be A/NZSASI’s biggest and best, so save the date. There is still a limited number of positions available for papers and presenters, so if you would like to present a paper addressing contemporary air safety investigation and air safety issues, please submit an abstract and short bio to Paul Mayes by 14 March 2012, at [email protected] To register, go to http://asasi.org/seminar/rego_main.htm where you can download a registration form.

One of these changes involves what were formerly known as Requests for Corrective Action, or RCAs. From 16 April 2012, RCAs will become Non-Compliance Notices (NCNs). While neither the substance nor the status of the notice has changed, the name change to NCN ‘tells it like it is’. It clearly shows recipients that CASA believes they have breached the regulations and are expected to take appropriate action to bring themselves back into compliance. Non-Compliance Notices also advise recipients to examine the underlying reasons why the identified breach occurred, and to take appropriate steps to rectify those underlying deficiencies.For more information, visit the CASA website at www.casa.gov.au/surveillance US Senate Passes FAA Bill A bill to speed the switch from radar to an air traffic control system based on GPS technology, and to open US skies to unmanned aircraft flights within four years, received final congressional approval on Monday. The bill authorises $63.4 billion for the Federal Aviation Administration (FAA) over four years, including about $11 billion toward the air traffic system and its modernisation. The system is central to the FAA’s plans for accommodating a forecast 50 per cent growth in air traffic over the next decade. Most other nations already have adopted satellite-based technology for guiding planes, or are heading in that direction, but the FAA has moved cautiously. The United States accounts for 35 per cent of global commercial air traffic and has the world’s most complicated airspace, with a greater volume and more varied private aviation than other countries. Within nine months of the bill’s passage, the FAA must also submit their plan as to how they will provide military, commercial and privately-owned unmanned/remotely piloted aircraft (RPA) safe access to airspace currently reserved for manned aircraft, to fly in the same airspace as airliners, cargo planes, business jets and private aircraft. Flight Safety Australia Issue 85 March-April 2012 The FAA must then provide these RPA with expanded access to US airspace currently reserved for manned aircraft by 30 September 2015. • the aircraft flight manual, or approved flight manual supplement, or Currently, the FAA restricts UAS/RPA use primarily to segregated blocks of military airspace, border patrols and about 300 public agencies and their private partners.

Flight Safety Australia examines some of the issues and trends involved For aviation, the good times are back in sight. The GFC held it at bay; continuing economic uncertainty in parts of Europe and the United States is still having an impact, but the pundits agree – forecast aviation growth will mean a shortage of trained personnel in the next decades. The International Civil Aviation Organization (ICAO), in its publication Global and Regional 20-Year Forecasts: Pilots. Maintenance Personnel. Air Traffic Controllers. (Doc 9956 Feb 2011), says the shortage will be especially critical in the Asia-Pacific region. No one learns to fly without some form of training. It’s the law that no one can perform more than minor maintenance on a VH-registered aircraft without being specifically trained for it. And, with the exception of the children of a certain US controller, amateurs are banned from control towers. In aviation, as in society at large, the trend is towards spending more time in formal education and training. In Australia in the 1930s, for example, only seven per cent of 16-17 year olds were at school. In 2010, the Year 12 retention rate was 79 per cent. During World War I trainee pilots frequently flew solo after as little as three hours, and could be instructing new pilots after 20 hours. In World War II, about six hours to solo was not uncommon. Today, any solo in a general aviation aircraft before about 10 hours raises questions about whether all the necessary skills have been taught. Fifteen hours is now considered an appropriate time before first student solo. Cabin crew, who began in the 1920s with a role combining advertising, reassurance and food service, are now part of an airline’s safety system and undergo intensive training in this Pilot attrition comparison: 2010 - 2030 60 000 40 000 Training capacities 20 000 Training needs 0 Surplus Shortage -20 000 Africa Graph adapted from ICAO report Asia/ Pacific Europe Latin Middle America East North America Flight Safety Australia Issue 85 March-April 2012 area. Engineers must now meet the challenges of rapidly evolving technology in materials, avionics and propulsion. Several common themes emerged as Flight Safety Australia spoke to pilots, engineers, academics, air traffic controllers and cabin crew about aviation training in its broadest sense. They were: the impact of supply and demand on training and safety standards, resilience, competency and experience, practical learning and theoretical or simulated learning, and the importance of continual learning. Supply and demand The big issue is that we’re going to be facing another global pilot shortage, says Roger Weeks, CASA manager, flying standards branch. ICAO’s global and regional forecast for pilots, maintenance engineers and air traffic controllers predicts the aviation growth rate is going to exceed four per cent per annum for each decade until 2030. It shows the Asia Pacific region will have the highest growth rate, with that region’s fleet projected to grow by 9.1 per cent annually. By 2030, that region will equal North America in size. The most likely scenario, ICAO says, is a training deficit worldwide of about 8000 pilots, 18,000 maintenance personnel and 2000 air traffic controllers every year – a grand total of 560,000 personnel over the next two decades. ‘Couple that with the age demographics – 30 per cent of pilots worldwide are aged over 50 – in 15 years they’ll be in their retirement phase. We’re certainly going to see a major issue, which we got a taste of in 2007-08 before the GFC, when the industry at all levels was under significant pressure. Schedules were being curtailed and aeroplanes were being parked because there were not enough crews to fly them.’ While supply and demand is not the regulator’s bailiwick, the challenge for us as a regulator is that if a shortage occurs that there’s no potential for any reduction in standards. We will need to be vigilant to ensure that does not occur.’ Weeks’s analysis is that, overall, pilot supply is squeezed by both boom and bust. ‘During the GFC, flying schools closed down; for example, in the Sydney basin three or four closed, and our figures show a 38 per cent reduction in the number of instructors being trained.’ ‘This level of infrastructure is not going to meet the increased training demand. ‘I think what we’ll see is two strong pathways in Australia, the traditional pathway of CPL, building your hours and approaching the airlines. Then there’s the new cadet model, with Rex establishing an academy in 2008 and Jetstar recently establishing a program.’ We won’t see the end of the standard direct entry model, but I believe we will see increased use of cadets’, Weeks says, adding that ‘cadet programs are not new, having been used by both Qantas and Ansett in the past and in widespread use internationally’. Resilience The mystery of what makes the perfect pilot, engineer, controller or executive is summed up in one of aviation’s most celebrated clichés – the right stuff. And, as with all clichés, it contains a grain of truth – there appear to be attributes that define the best in each of these areas. But research suggests that the actual right stuff is different from the popular perception. In a study published in 2001, US Air Force psychologist Raymond E. King, and academics Paul D. Retzlaff and Daniel R. Orme compared pilot psychological profiles to safety outcomes. 09 10 FEATURE Aviation training Their method was to examine the psychological assessments of air force pilots who had had accidents or incidents. They found: ‘Pilots who had received high scores on subscales related to self-assurance and devotion to duty were 3.75 and 2.39 times, respectively, more likely to have pilot-error mishaps/incidents. No relationship was found between mishaps/incidents and orderliness, achievement striving, self-discipline, and deliberation.’ How then do you train for this flexibility and resilience? ‘While counter-intuitive, it may be that these traits represent a lack of flexibility of the pilots such that they are less able to meet novel demands in crisis situations’, the authors wrote. They added a note of caution: ‘alternatively, those with higher feelings of competence, particularly in this relatively inexperienced sample, may have over-stretched their ability. Or, perhaps pilots with these traits are more likely to report significant incidents that fall short of a mishap. These interpretations are preliminary; more cases need to be collected and analyzed.’ Their findings correspond with a 1991 study by Charles L. Lardent, who found that pilots who had been involved in a crash were more conscientious, on average, than those who had not been involved in a crash. Lardent mentioned unrealistically high standards and reluctance to quit, even in the face of adversity, as potential dangers of excessive conscientiousness. The flexibility mentioned in King and Lardent’s studies is similar to what Professor James Reason in his most recent book, The Human Contribution, calls resilience. It is the factor that allows pilots, engineers and controllers to recognise, reduce and recover from the mistakes that are an unavoidable part of being human. Former airline executive engineering manager, Mark Sinclair, is now CASA’s executive manager of safety education and promotion. He says resilience is related to the ability to think laterally under stress. ‘It’s the capacity to join the dots and get to the real technical issue – to understand that the problem is not necessarily what it appears to be.’ And, you have to combine that lateral thinking with technical creativity to come up with an innovative solution to the problem’, he adds. Rodd Sciortino, Airservices Australia ATC academy training manager, describes resilience in the ATC context as the ability to make solid decisions under intense time pressures. It also involves continual assessment of those decisions and a willingness to adapt or abandon them if necessary. Former air traffic controller, Peter Cromarty, is now CASA’s executive manager of airspace and aerodrome regulation. He says humility is part of resilience. ‘You need to be decisive, with the self-confidence to stand by your own judgement. But you’ve also got to be flexible enough not to die in a ditch to make a plan work. You’ve got to be humble enough to change a plan if it’s not working,’ Cromarty says. Engineer Stuart Hughes, Australian managing director of human factors and safety management consultants, Baines Simmons, says confidence is essential. ‘You need be able to say, “I’m not happy with the condition of this aircraft. This is not right”.’ James Reason’s analysis of resilience in The Human Contribution uncovers more paradoxes. Some of the examples he quotes, such as the crash of United Airlines Flight 232, or the Air Canada ‘Gimli Glider’, involve improvisation, while others involve disciplined application of basic principles, such as the by-the-book sang-froid of captain Eric Moody and the crew of British Airways Flight 9 when volcanic ash stopped all four engines over Java. Teamwork How then do you train for this flexibility and resilience? Anthony Petteford, managing director of Oxford Aviation Academy, based at Moorabbin, says there is one factor that much pilot traditional training does not address: the ability to work as part of a team. This is essential for airline pilots, he says. Flight Safety Australia Issue 85 March-April 2012 ‘An airline pilot’s is a highly sophisticated role. It’s a specialist job that’s not just about flying skills any more,’ he says. ‘It’s a team management activity involving high degrees of automation in a hostile, dense environment. An airline pilot has to be trained for the profession from the outset, and that training must be ongoing. You wouldn’t train a doctor, dentist or lawyer to gain a basic qualification, and then go out into the world and work it out as they went along. Crew resource management is (or should be!) a well-known concept to commercial pilots, but Hughes says something similar is essential in the maintenance hangar. ‘There needs to be communication between management and maintenance people, asking, “how can we do this together?” Too often there is a disconnect between the maintenance function and planning, leading to unrealistic deadlines, which compromise safety’, he says. Dr Peter Bruce teaches aviation and aviation management subjects at Swinburne University in Melbourne. He argues that while pilots comprise probably 10 per cent of the aviation industry, the concepts of CRM, safety management systems and human factors are essential knowledge for anyone working in aviation, whether they be baggage handler or chief executive. Swinburne aviation students, whether in the pilot or management streams, all study many common subjects – including basic aeronautical knowledge and human factors – in their first year, ‘because we see it as an important part of the industry’. Rodd Sciortino says close cooperation is central to the ATC system of aircraft being handed on from one sector to the next. ‘One thing that’s not negotiable is teamwork. Every controller looks after the aircraft in their airspace and they need to ensure they progress safely through that volume on to the next volume,’ he says. But Petteford says embracing the team approach raises further questions about potential gaps in training. ‘Here’s something that has really raised a flag; there’s so much emphasis on “the pilot flying”. But do we really train pilots in the monitoring mode? What do we mean by that?’ he says. The question is as basic as where the pilot monitoring should be looking, Petteford says. ‘Everyone understands you’ll be doing the radio, monitoring systems, navigation logs and so on; stuff that supports the pilot flying. But during the final phases of approach should you be placing greater emphasis on monitoring the primary flight display, on looking out, or on the engines? Where should your eyes be and what should you be doing?’ This is such a primary question that the UK Civil Aviation Authority has commissioned a research study into the matter. ‘There are no answers yet, but I think there’s an awareness that we may have followed a standard model for too long.’ Oxford Aviation Academy - students in the briefing room 11 12 FEATURE Aviation training Competency and experience Well-publicised incidents involving Australian carriers and media interest have put pilot training in the spotlight. Some reporting has made much of the comparative lack of hours that some newly qualified airline pilots have when they first sit in the cockpit. A thousand hours of flying may involve 1000 different flights or the same flight 1000 times – the competency that results can be very different Multi-crew licensing, which trains ab-initio candidates to take the first officer’s seat in an airliner, is now throughout Europe and Asia, but is not yet offered in Australia. In this country, airline cadets are trained from having little or no aviation experience to a direct first officer role. Some schemes, such as the Jetstar cadet program administered by Oxford Aviation Academy, offer an additional module of multi-crew cooperation (MCC) in their training. Petteford is aware that some in Australia, with its stronger GA sector than Europe, see Oxford’s model as controversial. (Oxford’s model has operated in Europe since 1964.) ‘What we’re not saying, and what we’ve never said, is that you should completely rubbish other means of training,’ he stresses, ‘provided that when pilots are trained for their licence qualification that the training they undergo is structured, good quality and that, ideally, they do not enter into it without being pre-assessed’. ‘Some people go in with predetermined ideas that we’re not teaching people to fly, but both our ab-initio ATPL and (overseas) MPL courses have a mandatory upset avoidance and recovery component. The primary emphasis is avoidance, not just recovery. We’re trying to develop an intuitive thinking that they should constantly be evaluating threats and errors to avoid being upset in the first place.’ Flying instructor Steve Pearce, a holder of the Royal Federation of Aero Clubs Australia Master Instructor award, is among the voices that say nothing replaces time in command of an aircraft – of any size. ‘My personal view is that I want someone in the right-hand seat who’s done the hours, the hard yards, and has the experience to draw on. Oxford Aviation Academy - King Air used for training The concept of someone who’s got the experience in the simulator, but not in the real world, is hard for me to get my head around.’ However, Petteford argues that structured ab-initio training can respond to safety trends in a way that individual pilots working their way through the informal progression system of night freight, charter and low-capacity regular public transport operations cannot do easily. ‘During our second Flybe MPL course, the airline has asked us to increase the amount of handflying on instruments – power plus attitude – partly as a result of the Air France accident,’ he says, as an example. CASA’s Roger Weeks says both experience and competency are necessary, but ‘there is some exclusivity to the two.’ Experience doesn’t necessarily guarantee competence and competency-trained low hours pilots are by definition inexperienced. Flight Safety Australia Issue 85 March-April 2012 ‘Experience does count, but competency also counts,’ Weeks says. ‘A thousand hours of flying may involve 1000 different flights or the same flight 1000 times – the competency that results can be very different.’ However, Pearce firmly believes there is ‘no substitute for command hours, regardless of type. It’s in the subconscious, for you to draw on.’ Practical vs simulation The competency vs experience debate sometimes merges into a discussion of the merits of simulator vs real-world training. (Flight Safety Australia looked at this topic in ‘When to Sim?’ November-December 2010.) What is not as widely appreciated is how simulation is being applied to fields other than pilot training. Swinburne’s aviation and aviation management students continue to encounter safety in the second and third years. The bachelor of aviation and bachelor of aviation management courses use an airline business simulation to teach airline management to senior students. ‘They buy aircraft, set up route structures, schedules, and make decisions about fares, advertising, staffing, catering and seat configurations’, Bruce explains. Swinburne aviation senior lecturer, Dr David Newman, says simulation teaches the relationship between safety and organisational culture in a way that classroom lectures cannot. ‘The same things happen in simulation as in the real world. We get fare wars, mergers and alliances, requests for bailouts’, he says. The simulation reinforces that safety underpins profit, he adds. ‘Safety is an emphasis throughout the whole course and students are well aware of how the brand is affected by safety. ‘If they don’t do maintenance properly, the aircraft become unreliable and may crash. Then people won’t travel with their airline, no matter how much they discount.’ Bruce continues: ‘Through subjects like SMS, the course tries to prepare students to be aware of the safety systems and culture in aviation, not only in airlines but in airports, and the system overall. Newman adds, ‘If you have a safety issue in a retail business, you might get a fine from the occupational health and safety authorities. But in the airline, a safety issue can threaten the viability of the business, not to mention people dying. It’s a commodity-based business, selling seats; but it’s also volatile, dynamic, safety critical and very much in the public eye.’ Airservices Australia and its predecessors have used simulators for many years in ATC training, but Sciortino says they are now of a standard that can deliver highly sophisticated scenarios in high fidelity. Top to bottom: Swinburne University’s fixed-wing simulator; inside Swinburne’s helicopter sim: Hong Kong at night; and on approach to Bankstown 13 14 FEATURE Aviation training ‘There are still the core competencies and things we need to instruct. Our tower visual simulator is a 360-degree simulator that can be loaded with any scenery in Australia,’ he says. Airservices also has a radar simulator and Eurocat en-route simulator. Good engineers ask “what can I learn next?” You never stop learning. ‘[Simulators] were more rudimentary in the old days. In the ’80s, the tower simulator was watching a slide show. The dot above the Mt Macedon range was meant to be an F-27 on final. Now we can press a button and create rain, low cloud, night or fog. We can thoroughly test the controller.’ Sciortino says the simulators allow an integration of theory and practice that was much more difficult in the days of classroom-only instruction. ATC trainees study in a sandwich structure beginning with theory, simulation, further theory, a second round of simulations and, finally on-thejob training under supervision. CASA’s director of aviation safety, and former Cathay Pacific flying training manager, John McCormick, says simulators are good predictors of successful pilots. ‘Piloting is first and foremost a psychomotor skill. If you cannot think and fly the aircraft at the same time you are in the wrong occupation’, he says. ‘When I look at my logbook of the pilots I checked in simulators, there is an absolute 100 per cent correlation between people who could fly the simulator well and those who went on to senior positions in the company.’ Lifelong learning Although there are some sharp differences of opinion about training there is one common point of agreement: it should never stop. All the experts interviewed stressed the importance of lifelong learning for anyone making aviation their career, or hobby. ‘An American writer, Richard S. Drury, said we’re all student pilots until we retire, I think that sums it up perfectly’, says Pearce. ‘We’re in a learning environment for the whole of our careers.’ Part of lifelong learning is mentoring, which Pearce finds valuable because it often allows two-way learning: the teacher learning from the student as well. ‘I’m only ever a phone call away’, he tells his former students. CASA director, John McCormick, emphasises the importance of contextual knowledge. ‘If you say, “I’m going to be a pilot,” that doesn’t mean you never read anything again about general business or management. You’ve got to have an understanding of how your occupation fits into the grand scheme of that’, he said. Petteford says pilot training should not just be ongoing and set against regulatory minimum requirements; it should be tailored to a ‘training needs’ profile (pilot and airline). ‘One should take training records and evaluate the strengths and the potential threats/errors and use them as a means to tailor ongoing training design.’ Weeks says the key thing is to look at the big picture. Where are the accidents happening and what is being done to address these issues in training? Training for the big three killers: loss of control, runway in/excursions, and controlled flight into terrain should not just be the domain of airlines and air forces. This philosophy extends into the hangar, the office and the tower. Sciortino says the cycle of assessment and training in ATC is, in effect, continuous learning. ‘I tell our students, “Get used to being under scrutiny, whether it be with an instructor behind you every day for the next 15 months or, once you get your licence, having a check controller behind you every six months”.’ Hughes says ‘Good engineers ask themselves “what can I learn next?” You never stop learning.’ Flight Safety Australia Issue 85 March-April 2012 CASA Training Centre CASA is setting up a new training centre at its Brisbane offices, due to open in the second half of this year. ‘The Centre’, CASA executive manager education and safety promotion, Mark Sinclair, explains, ‘is not teaching the basics of how to be a pilot or an engineer’. Rather, its focus is squarely on ‘helping to build a baseline of regulatory skills, so that CASA delegates, or key personnel in an aviation organisation, understand the core regulatory competencies associated with that function and know what we expect of them’. At the Centre, people in key positions, such as accountable managers, safety managers, delegates, responsible managers, approval personnel (and those aspiring to be), will develop an understanding of their regulatory obligations, and the expectations CASA has of such roles. ‘As we progress to the outcome-based style of legislation, organisations will have the ability to better self-manage,’ Sinclair explains. ‘But at the same time, with that flexibility comes responsibility, and a certain required level of maturity. The Centre is about assisting key individuals in these organisations to develop that level of maturity.’ NGAP CASA flying training and education managers are contributing to ICAO’s global effort to address the forecast shortage of aviation personnel, and build training capacity. ICAO is holding a series of regional conferences and global symposiums focusing on the issue, under the title of the ‘Next Generation of Aviation Professionals’ (NGAP). The first NGAP symposium was held in Montreal in early 2011, followed by a round of regional conferences. The second symposium will be held in Montreal in April of this year (2012).

For aviation safety to continue to improve, aviation organisations not only have to comply with the rules, but then move beyond that basic (and fundamental) compliance to a new level. At this next level, every person in an aviation organisation strives for safety by identifying hazards, evaluating risks, communicating them and taking steps to mitigate them. As the regulator for the Australian aviation industry as a whole, it is appropriate that CASA does this. But CASA cannot regulate against the unique and ‘unknown unknowns’ hazards that may reside with individual operators. They must observe, analyse and improve their own safety. That’s where safety management systems (SMS) come in. New regulations in place and underway, mean that organisations will need to have SMS in place. But what are the hazards? A safety management system is an approach to safety that shares its logic with former US Secretary of Defense, Donald Rumsfeld’s, sometimes derided ‘unknown unknowns’ phrase of 2002. Rumsfeld said: ‘There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – there are things we do not know we don’t know. CASA is working on a resource kit, SMS for Aviation—a Practical Guide, to assist organisations with SMS, whether they are updating and improving an existing system, or developing and implementing a new one from scratch. It is practical, written in plain English, and takes a jargon-busting approach. The set of six booklets outlines the structure of an SMS, following the global ICAO framework. The kit includes: 1.An introductory booklet: Safety Management System Basics – why have an SMS? What’s in it for me? What is the difference between an SMS and a quality management system? Safety Management System Basics also includes jargon busters: a list of useful definitions and abbreviations/acronyms. Similarly, in aviation there are hazards that we don’t know about and we don’t even realise that we don’t know them: a flight management system inundating a crew with more than fifty error messages, for example. There are no rulebooks and checklists to guard against these so-called ‘black swan’ hazards (from Taleb’s 2007 book, The Black Swan, where he talks about ‘black swan’ events as being undirected and unpredicted). Only a safety management system based on constant alertness, reporting, analysis and mitigation can hope to discover and address them. Hazards may be latent in new aircraft types, buried in new or time-honoured procedures, or inherent in certain destinations.

Safety policy, objectives and planning Good safety management is not about having an SMS manual on your shelf, outlining each of the elements you have in place. Safety policy, objectives and planning looks at the vital role of management in having an effective SMS, setting up roles and expectations, clear policy guidelines, and making sure everybody in the organisation, whether it’s big or small, knows about and supports the SMS. • SMS for Aviation—a Practical Guide. Safety risk management With policies and people in place, the next step in an SMS is to identify the hazards in your organisation, and to make sure you have controls to manage risk. This booklet looks at managing risk, the idea of reducing risk to be ALARP (as low as reasonably practicable) and ALoS (acceptable level of safety) and provides templates and checklists such as a sample risk register and hazard ID. • SMS for Aviation—a Practical Guide. Safety assurance Safety assurance is the way you show that your SMS works, so this booklet looks at ways to monitor and record your safety performance. It includes investigation, reporting and auditing; as well as important things to consider in managing change. S E R V I C E • SMS for Aviation—a Practical Guide. Safety training and promotion Good communication is vital for an effective SMS. If the boss keeps everyone in the loop on safety issues, and in turn, listens to what employees have to say, the SMS will be much more effective. Equally, part of an effective SMS is ensuring employees have the skills and knowledge they need. This booklet therefore focuses on the ‘safety training and promotion’ part of an effective SMS. 3.Booklet 6 in the SMS for Aviation—a Practical Guide kit is Human Factors, dedicated to promoting an understanding of humans—our behaviour and performance. Then, from an operational perspective, we apply that human factors knowledge to get the best fit between people and the systems in which they work, to improve safety and performance. 4. A DVD containing all the checklists and templates is included so that organisations can adapt these to suit their individual needs. The kit is due for release by mid-2012, and will be widely publicised.

The Stage 1 report reached three main conclusions: CASA fully supports the continued operation of ageing aircraft in Australia – providing it can continue to be done safely. Aircraft owners may not be able to continue operating the existing fleet of ageing aircraft indefinitely, with only a minimal amount of the existing type of maintenance, and expect the inherent risks to remain at an acceptable level. Identified ageing issues are affecting the continuing airworthiness of aircraft. Stage 1+ took place in 2011 and involved providing feedback to industry on the findings of Stage 1 and delivering an aircraft owner awareness program on the science of aircraft ageing. This was done via the CASA website and through a series of seminars around the country in metropolitan and regional venues. Stage 2 includes further seminars this year following the successful 2011 round. These seminars will be fewer in number but larger in scale than those that took place across the country last year. ‘We’ll go for larger venues,’ van Dijk says. Stage 2 also involves preparing a discussion paper and developing ageing aircraft training programs, both of which are scheduled for release in mid 2012. A prototype online matrix tool is also under development to allow aircraft owners to assess the degree to which the many factors in aircraft ageing affect their aircraft. ‘We want to have this facility available for industry to trial so owners can run some “what-if” scenarios on the airworthiness status of their aircraft,’ says van Dijk. ‘The online tool leads the person through a series of questions about their aircraft, based on engineering and scientific facts—nothing subjective. At the end, the answers to each question will produce a likelihood index number, which will give an indication of the likelihood that their aircraft is affected by ageing issues. The questions include a range of objective data fields including the type of aircraft, its certification basis, whether it has ever been damaged, how it has been repaired, how it has been operated and where it is usually kept (in a hangar, on grass, or near the coast). ‘You can enter your individual aircraft’s details and get some idea of whether you should be making some fundamental changes to it, or its maintenance system.’ Later this year CASA intends to publish a notice of proposed rule making, after the responses to the ageing aircraft discussion paper have been assessed. A notice of final rule making should follow in mid to late 2013. All interested industry parties are invited to comment on CASA’s proposed initiatives to manage ageing aircraft. One trend that has emerged in the Stage 1 investigation is that ageing aircraft are primarily a general aviation problem. Flight Safety Australia Issue 85 March-April 2012 Aircraft in the airline transport sector are more heavily used than most GA aircraft, but they also tend to be both newer and more comprehensively maintained. ‘We’re less worried about airline transport aircraft,’ van Dijk says. ‘They are very intensively used, but that’s fine, as their systems of maintenance are continuously monitored and improved.’ ‘That’s a different situation to GA, where the systems of maintenance haven’t necessarily been adapted over the years to include ageing-related issues.’ Stage 1 was somewhat reassuring in that it confirmed what we know about the issue of metal fatigue as part of ageing. For details of the 2012 seminars,see the full-page ad on the inside front cover of this issue. ‘Corrosion has turned out to be a more significant issue than fatigue,’ van Dijk says. ‘It seems we’ve managed fatigue reasonably well over the years, but corrosion is a lot more prevalent than we anticipated. ‘If you have a hard-to-get-to bit of the aircraft, chances are it’s not been looked at for decades, and chances are also that it will have corrosion damage. That’s significant because corrosion damage compromises the structural strength of the aircraft.’ Wiring emerged as another significant factor in ageing. Some GA aircraft more than 40 years old were seen by the ageing aircraft team to be still flying with their original circuit breakers and wiring. ‘Original wiring in a 40-year-old aircraft is not going to be reliable,’ van Dijk says. ‘To fly in IMC with ageing wiring is to put your life in the hands of some cracked-up, ageing wiring insulation that could easily be your undoing.’ The schedule of maintenance, known as CASA Maintenance Schedule 5, calls for aircraft wiring to be inspected, but does not provide any guidelines for its replacement. Therefore wiring often goes unreplaced for decades. ‘Schedule 5 was never intended as a catch-all for large fleets of aircraft that are twice as old in age and hours as manufacturers originally expected them to be,’ van Dijk says. ‘It was initially designed several decades ago as a schedule of maintenance for a few orphan aircraft that did not have adequate maintenance data available from their manufacturers.’ The concept of a minimum maintenance standard is obviously valid, but there is a strong case that its current content needs to be updated into some sort of enhanced Schedule 5.’ All these concepts will be discussed in full in CASA’s upcoming discussion paper and notice of proposed rule making on the topic. www.casa.gov.au/ageingaircraft 23 24 FEATURE Air traffic management reforms Change in the air After a long period of consultation and development, which began in 2010 with an initial discussion paper, CASA is close to finalising important air traffic management (ATM) reforms. Broadly, the proposed changes involve requiring operators of certain aircraft to fit avionics equipment to enable safe and efficient utilisation of new technologies supporting future ATM and satellite navigation. The proposed changes come at a time of increasing global harmonisation of ATM and satellite navigation standards. Historically, these changes have been developed in a co-operation with ASTRA* members as an acceptable compromise between the various industry sectors. The changes mainly affect IFR and do not affect Class G airspace below 10,000 feet. (*ASTRA, the Australian Strategic Air Traffic Management Group, is an aviation industry body dedicated to developing an optimum air traffic management system for Australia. ASTRA members include the airlines, CASA, Airservices, the Aircraft Owners and Pilots Association, the Regional Aviation Association of Australia, the Australian Sport Aviation Confederation, the Australian & International Pilots’ Association and others.) In Australia, too, there are powerful drivers for change. Australia is at a watershed in its ATM, with many legacy ground-based navaids, such as non-directional beacons (NDB) and VHF omni-range (VOR) equipment, approaching the end of their useful life. The intention is to complete the transition to satellite navigation, which commenced in 1995, by early 2016, while retaining selected navaids to back up and mitigate any problems with GPS. Airservices is also providing new Mode S radars, multilateration at major city airports, wide area multilateration (WAM), and more ADS-B ground stations are being commissioned to provide improved services, coverage and increased safety. ... for ongoing safety and efficiency, CASA is proposing a number of changes to avionics equipment Another factor is increased air traffic: Western Australia’s growing mining activity, for example can mean that aircraft are unable to enter or leave Perth controlled airspace when they request. The fact that en-route ATM outside radar is presently handled by procedural methods, with a 50nm procedural limitation, affects the amount of traffic in the airspace around Perth. Consequently, for ongoing safety and efficiency, CASA is proposing a number of changes to avionics equipment. These changes apply especially to satellite-based IFR navigation; fitting of Mode S/ADS-B (automatic dependent surveillance – broadcast) transponders; and fitting of the updated version of the traffic collision avoidance system—TCAS II version 7.1. Flight Safety Australia Issue 85 March-April 2012 Comments of the Notice of Proposed Rule Making 1105AS, circulated in January 2012, close on 13 March.

CASA mandated this mandatory fitting of ADS-B in 2009. ‘We are now seeing over 70 per cent of all international flights in our flight information region getting the ADS-B service,’ said Airservices senior engineering specialist and ADS-B program manager, Greg Dunstone, in December last year. ‘A small number of airlines and business jet operators appear not to have made the move to have ADS-B installed. They need to get a move on, because the effective date is fast approaching,’ Dunstone added. CASA is not expecting to issue exemptions. After 12 December, 2013, non-ADS-B equipped aircraft will have to operate below FL290, with the corresponding disadvantage of less operational flexibility and potential delays because of procedural separation standards applied outside radar airspace. 25 26 FEATURE Air traffic management reforms What is ADS-B? Using ADS-B Simply, automatic dependent surveillance - broadcast, or ADS-B, is aircraft automatically sending flight information to air traffic control and to each other. ADS-B systems typically broadcast two means of identifying the transmitting aircraft. The first is a technical means called the aircraft address (also known as the 24-bit code) and the second is the flight identification (FLTID)—the visual equivalent of a call sign—used to identify targets on a display and link them to their flight plans. ADS-B broadcasts information about an aircraft, including its: identification position altitude (barometric and/or geometric) speed direction The system also broadcasts technical information, such as position integrity/accuracy. This data is automatically sent about every half-second. The system takes its information from other aircraft systems: a barometric encoder for altitude, and global navigation satellite system (GNSS) equipment for speed position and direction data. The initials ADS- B describe the main characteristics of the system: Automatic—the system requires no human input. No radar is needed to interrogate it. Dependent—the system relies on information from aircraft systems. Surveillance—the system allows ATC, and individual aircraft with cockpit displays of traffic information (CDTI), to see a picture of air traffic in an area. Broadcast—the system is a broadcast to all listeners, rather than directly to a known receiver. Airservices Australia completed the installation and commissioning of its nationwide automatic dependent surveillance-broadcast network in December 2009, with Australia becoming the first in the world to provide nationwide ADS-B coverage. ADS-B is available to suitably-equipped aircraft at all flight levels within coverage of ground stations at 29 sites throughout the country, providing radar-like coverage over continental Australia for the first time. ADS-B data is also received by wide area multilateration (WAM) systems in Tasmania and at Sydney. The accuracy of the information displayed on air traffic controllers’ screens allows separation standards to be reduced from 30nm to 5nm. Level off! Level off! TCAS stands for traffic collision avoidance system, which has evolved through several versions since first introduced in 1990. TCAS II V7.1 is an enhancement that verifies pilot response to a resolution advisory (RA) and may generate a TCAS resolution reversal, and changes the verbal advisories from ‘adjust vertical speed, adjust’ to ‘level off, level off’. This enhancement came in response to the Uberlingen mid-air collision of 2002. In that accident, 71 people were killed when a Boeing 757 and a Tupolev 154 collided over southern Germany. The Tupolev crew had followed conflicting directions from the controller instead of obeying TCAS alerts. ICAO is mandating TCAS II V7.1 on/after 1 January 2014. All public transport, turbinepowered aircraft above 5700kg certified to carry more than 19 passengers, first placed on the Australian register on/after 1 January 2014, must have TCAS II V7.1 before they can fly. Flight Safety Australia Issue 85 March-April 2012 Aircraft identification The aircraft identification (sometimes called the flight identification) is the equivalent of the aircraft call sign and is used in both ADS-B and Mode S-SSR technology. It is up to seven characters long, and is usually set by the flight crew using a cockpit interface. It enables air traffic controllers to identify an aircraft on a display and to correlate a radar or ADS-B track with the flight plan data. Airline aircraft should use the three-letter ICAO airline code used in flight plans, not the two-letter IATA codes. For aircraft using registration, the code should exactly match the flight plan. For Australian domestic flights the preceding ‘VH’ should not be included. Aircraft identification is critical information, so enter it carefully. Punching in the wrong characters could lead to ATC confusing your aircraft with another. It is important that the identification exactly matches the aircraft identification (ACID) entered in the flight notification. Intuitive correlation between an aircraft’s identification and radio callsign enhances situational awareness and communication. Each aircraft has a unique aircraft address, which consists of a 24-bit code allocated by CASA. This code is usually entered into the unit by a LAME at installation. The code is on the aircraft registration letter sent to aircraft owners by CASA. If your aircraft is not registered by CASA, you can get a code from the aircraft registry. S for safety ADS-B broadcasts are made using Mode S, the same standard as used on Mode S transponders, which are replacing the Mode A/C transponders used in radar surveillance. ADS-B enables automatic safety alerting within the ATC system including short term conflict alert and cleared level adherence monitoring. This is already active across the whole continent for equipped aircraft. Mode S has less signal garbling, less erroneous data, and allows aircraft call signs to be displayed on the ATC radar screen. Mode S transmits a unique 24-bit aircraft address to greatly reduce the probability of identification errors. Aircraft address 27 FEATURE AvSafety seminars CASA’s successful AvSafety seminar series returns in 2012 with two new topics added to the line-up. And … you can now register online to attend the next seminar in your area. AvSafety seminars are aimed at everyone in the aviation community, and are held in regional centres, as well as in capital cities. In 2011, more than 5000 people attended 120 AvSafety seminars run by CASA across the nation. The 2012 seminar program continues with a new focus on two key issues: aviation safety resources on the internet and human factors in aviation. There is a wealth of official and unofficial information on aviation to be found on the internet, but the key is understanding where to find the official information you need. The ‘aviation resources on the internet’ seminar will guide attendees on how to find information on the official websites most people in aviation need to use: CASA (www.casa.gov. au), Airservices Australia (www.airservicesaustralia.com), the Bureau of Meteorology (www.bom.gov.au) and the Australian Transport Safety Bureau (www.atsb.gov.au). The seminar will demonstrate how to find training materials, general information, advice and regulations, as well as how to lodge reports (such as SDRs—service difficulty reports) and access self-learning resource centres. The aim of the seminar is not to explain each of the websites in detail, but to give attendees an understanding of the sort of information they contain and to encourage attendees to explore them on their own. (*A new companion kit, Safety Behaviours—Human Factors for Engineers, is in production, due for release in June 2012. To ensure consistency of the two kits, the Safety Behaviours— Human Factors for Pilots is being reprinted. It is therefore not available from the CASA online store until late April; however, until then, it can be downloaded from the resources section of the Skybrary website – www.skybrary.aero) Both topics are applicable to all members of the wider aviation community. The safety seminar program also covers a wide range of other topics, from airmanship to glass cockpits, and maintenance to fuel management. Go online to the ‘Seminars and Workshops’ section of the CASA website (which you can find via the Education dropdown menu on the top navigation bar) to request a seminar in your area. All seminars are sponsored by CASA, and are free to attend. LIMITED AVAILABILITY ! Seminars 2012 … New Year, New Look The ‘human factors’ seminar looks at how an understanding of human performance is important to the safety of all aspects of aviation operations. The seminar uses the kit, Safety Behaviours—Human Factors for Pilots*, produced by CASA, as its major resource. There will be a focus on the major elements that make up the study of aviation human factors and a demonstration of how they can be applied in a practical way to everyday operations. People attending this seminar will be provided with resources so they can research in greater detail the aspects of human factors relevant to their operations. This topic is vital as human factors is fast becoming a major safety focus for both CASA and the International Civil Aviation Organization (ICAO), and a required part of new aviation regulations.

Er, not quite—the truth has been available for years. But any chance to revisit the fundamentals of lift is worth taking … Professor Holger Babinsky, of Cambridge University has been mildly annoyed at the persistence of the ‘equal transit time’ fallacy for many years. This is the sentence that persists in popular explanations, including some aviation theory textbooks (Babinsky found one at his daughter’s school). It says that when the airflow separates to go over and under a wing, Bernoulli’s principle dictates that the upper and lower streams will meet at the same time at the trailing edge. So when Cambridge University proposed he contribute to a series of Science in a Minute videos he had a ready topic. ‘The university wanted to accompany this by a press release and it all took off from there,’ he told Flight Safety Australia. ‘In the university statement we have been very careful to avoid giving the impression that this is new.’ Photos: Screen captures from Cambridge University’s video His video, posted on YouTube, (and at http://preview.tinyurl. com/6wyfea6) uses interrupted smoke streams to show that the top stream arrives at the wing’s trailing edge much sooner than the lower stream. Under this explanation there is no prediction that air from above and below the wing must rejoin at the same time at the trailing edge. ‘There is no need even to introduce Bernoulli’s equation,’ Babinsky concludes. A 2003 paper by Professor Babinsky in Physics Education (at http://preview.tinyurl.com/72bnyeq) explains what is happening. CASA engineer, Neville Probert, does not believe Bernoulli’s principle should be thrown out. But he agrees that equal transit time is a demonstrable fallacy. Air moving over a wing can be thought of as layers of streamlines—and smoke streams in a wind tunnel can illustrate these. Babinsky says ‘the wing’s airfoil shape causes curved streamlines, centripetal force acting on the air, and a progressive drop in pressure towards the centre of curvature of the streamlines’. This accounts for the lower pressure on the upper surface of a wing. There is a also a downwards flow of air as it leaves the wing (as any student pilot who has tried to land a low-wing aeroplane can attest). ‘It is important that pilots accept the practicalities of lift and have a sound understanding of the implications for drag, stalling and spinning,’ he says. ‘There are a number of suitable explanations to choose from. Pilots should choose the explanation of lift that they find most satisfactory and that matches their background knowledge.’ Babinsky is philosophical too. ‘Clearly Wednesday (25 January) was not a big day for news but the response has been overwhelmingly positive.’ Flight Safety Australia Issue 85 March-April 2012 The trouble with cables Aircraft owners have had a timely reminder of the importance of flight control cable maintenance. The basics of cable maintenance are as important as ever, particularly given the ageing of some of the Australian general aviation fleet Flight Safety Australia’s January 2012 story about a control cable failure turned out to be only the first chapter in CASA’s response to the issue. Between printing and distribution of the magazine more cases of control cable wear or failure in some Beechcraft aeroplanes were discovered, prompting a series of airworthiness directives for mandatory inspections of the cables on Beechcraft Debonair, Bonanza and Baron models. Seven cases of frayed or broken cables have been found so far in response to the directives. But no aircraft owner can afford to be smug. Cables are critical maintenance items on any aircraft that uses them because of their obvious importance to flight control. Regardless of age, cables require close attention. They are a maintenance sensitive item. There are five major points about cable maintenance aircraft owners and maintainers should revisit, particularly at this time. 1. Wear Under normal use cables wear, unavoidably, in two ways. External wear comes from the abrasion of the cable’s individual wires, coming into contact with pulleys, guides, rubbing strips or, sometimes with poorly installed wiring or other fittings. A recent service difficulty report describes an egregious piece of mis-rigging. The elevator trim cables on a single engine aircraft had been replaced, but mis-routed, which brought them into contact with an electrical wiring loom. Someone who should have known better wrapped the electrical cables in tape in an effort to prevent the cables from cutting through the electrical wiring. An unusual feature of external wear is that it seems to affect cables that make small direction changes at pulleys more so than cables that make sharper direction changes. Lightly loaded pulleys, for example, may revolve slowly during flight in response to engine vibration, wearing the cables. Cable wear patterns Source: Figure 7-17, Advisory Circular 43.13-1B Internal wear is much more difficult to detect, and comes from wires and strands in the cable rubbing against each other at the point where the cable changes direction over a pulley. Internal wear is greatest at the point where the cable changes direction, and is related to the radius of the direction change. A small radius produces more internal wear, as the cable has to bend more sharply. 31 32 AIRWORTHINESS The trouble with cables 2. Fatigue Related to wear is fatigue, which can take the form of work hardening and brittleness of individual wires, or strands of wires, in a cable. Fatigue is an inevitable consequence of a cable doing its job over several years, but can be accelerated when aircraft are parked in the open with their flight controls locked in the cabin and the control surface still free to move. The movements caused by wind on the ground take a toll on the cables that may be the equivalent of hundreds of hours extra flying time. To combat the effects of corrosion on coated carbon steel cables, some manufacturers have introduced stainless steel cables. While this seemed a good idea at the time - stainless steel is a very effective material in marine use - they have been found to wear far more rapidly than plain old, plated carbon steel. An FAA special airworthiness inspection bulletin (SAIB: CE-12-01) says manufacturers are now moving away from stainless steel. This is backed up by CASA’s considerable case log of wear-related failures in stainless steel cables. However, the effects of fatigue can be minimised, or at least brought to acceptable levels, by correct maintenance of cables. The FAA now recommends that stainless steel cables only be used in marine environments where corrosion is a major problem. 3. Corrosion 4. Tension Corrosion is another enemy of cables. The extent and rate of corrosion is affected by where the aircraft is flown and stored. Cables that run near batteries, toilets and galleys, or that are exposed in wheel wells, or other open areas, are particularly susceptible to corrosion. Corrosion pitting on the cable acts as a stress raiser and significantly reduces the fatigue life of a cable. Another characteristic of cable corrosion is that it can be insidious. Cables can be riddled with it while appearing sound from the outside. The literature on cable wear and maintenance dates well beyond 1957, but in that year, an airworthiness directive was brought out for Auster A61 aeroplanes following a series of rudder cable failures. The AD required that the cables be removed and inspected every 100 hours. The cables had failed mostly due to fatigue, it seems, after vibrating in response to frequency generated by the aircraft’s engine, propeller or airframe. There is at least one well-documented anecdote of an apparently serviceable looking cable with a very sound coating of anti-corrosive compound which snapped when an engineer accidentally leaned on it. The commuter aircraft’s flight control cable was riddled with corrosion beneath its covering of anti-corrosive compound. The compound had served to retain moisture: as well as keeping water out, it also kept water in. If cables were improperly tensioned, in effect, they behaved like guitar strings becoming more sensitive than they should be to the vibrations from the engine and propeller. As a general rule, under-tensioned cables are subject to lowfrequency vibrations, and over-tensioned cables are subject to high-frequency vibrations. This is in addition to the problems of loose control feel that result from under-tensioned cables and tight control feel, sometimes coupled with restricted range of motion, that accompanied over-tensioning. The solution is tensioning the cable to manufacturer specifications, using an accurate and calibrated tensiometer and thermometer.

Temperature The cable tension is frequently specified by the manufacturer for a certain temperature range. This is because an aluminuim fuselage expands and contracts at a different rate to the steel cables. If cables are not correctly tensioned it can result in the cables going slack in cold weather or at high altitude. It can also result in cables becoming too tight during hot weather. The need to check It is to be expected that there will be more cable changes done this year in response to CASA’s series of airworthiness directives. When cables are changed, duplicate inspections for correct run and correct response to control surface are critical. But cable replacement has its own hazards. It has been known for aircraft to have passed through these inspections, and still have their controls rigged incorrectly - even backwards. As in so many areas of aviation you, the pilot, are your own last line of defence. One thing you can tilt in your favour is your daily/pre-flight inspection. Take advantage of the quiet, Cable inspection technique Source: Figure 7-16, Advisory Circular 43.13-1B before the engine starts and gyros start running up, to really listen when you move the controls. Is there any unusual noise or binding when you move the control column or surfaces? Later, at the threshold, check again, and not just a cursory glance. Do the controls really move in the right direction? Do they really feel free? A few moments of sensitive observation before you commit to the sky could save you from being the victim of a cable catastrophe. 33 34 AIRWORTHINESS Pull-out section SELECTED SERVICE DIFFICULTY REPORTS 19 Nov 2011 – 6 Feb 2012 Note: Similar occurrence figures not included in this edition Aircraft above 5700kg Airbus A320212 Elevator, spar/rib rib corroded.

It is entering general and sport aviation almost by stealth, as accident investigators exploit the data-recording potential built into modern consumer electronics. ‘There’s some digital data in almost every crash now,’ says Alex Talberg, technical investigator with the Australian Transport Safety Bureau (ATSB). ‘Most electronics these days uses flash memory, whether it’s for processing data or for storage of dates or last known information.’ ‘Flash memory can withstand huge impact loads and fairly high temperatures. I’ve seen research that says that data is only completely lost at 450 degrees Celsius. It’s generally a stable and robust recording medium.’ Recreational Aviation Australia (RA-Aus) operations manager, Zane Tully, says some modern GPS units automatically record and store a history of height and track data of the aircraft’s most recent travels. In older versions this function may need to be enabled, he notes. ‘In many cases a GPS unit’s memory was downloadable and when analysed, provided valuable information about the fateful flight.’ ‘The ATSB generously assists RA-Aus (and the police for that matter) with data recovery from all types of devices like: GPS, EFIS, iPad and even engine management systems that have inbuilt data recording software and memory,’ Tully says. Flight Safety Australia Issue 85 March-April 2012 Among the devices that cross Talberg’s desk after a crash are smartphones GPS receivers, (‘we see a lot of them, often damaged’), fuel computers, engine monitoring units and engine management systems. Engine electronics contain flash memory for data logging, or to store the maps of engine fuel, ignition and spark configurations. ‘We get on average now two or three devices to work on from any aviation accident. We’ll often get a portable GPS or a phone. There was one accident where there were four people on the aircraft and three smartphones were recovered,’ Talberg says. We had another accident where we had a GPS and an iPad. The GPS recorded up to five minutes before the accident because of buffering, which is where it records to volatile memory and then transfers that on to its non-volatile memory. Because of that buffer we lost the last five minutes of data on the GPS, but the iPad we analysed had exactly the same track, but continued all the way to impact.’ The electronic devices that end up on Talberg’s desk fall into two categories: undamaged units, from which information is relatively easily downloaded; and damaged units, which require one of three techniques to extract their secrets. ‘First, we try to fix the device,’ says Talberg.’If that doesn’t work, we transfer the memory on to a “golden chassis” unit and download from it that way, substituting a working unit for the damaged one. The third alternative is to download raw binary data from the flash memory itself. You get binary data of zeroes and ones that has to be interpreted. We then either work with the device manufacturer to decode it, or reverse engineer the information by downloading known data on an identical device.’ Clues to a Spitfire mystery On 22 October 2010, a replica Supermarine Spitfire MK26 recreational/light sport aircraft crashed near Gympie authorised landing area, in Queensland, killing the pilot, Barry Uscinski, 75. A former defence scientist and academic, Uscinski was also a highlyregarded, aerobatic-rated GA pilot. Recreational Aviation Australia (RA-Aus) assisted the Queensland Police in their investigation of the crash. Although it had no flight recorder, the Spitfire replica had an automotive engine with a Motec M600 engine management system. The ATSB undertakes about three investigations annually involving this level of in-depth data recovery from damaged electronic devices. Talberg says a global community of investigators is developing, based around sharing information on how to extract data from electronic devices. RA-Aus asked the Australian Transport Safety Bureau (ATSB) for technical assistance to recover data from the M600’s flash memory. ‘One of the first things we’ll do is ask several international agencies if they have had any experience with similar units,’ he says. A complicating factor is the rapid evolution of consumer electronics, which means that different models of the same device may use different components behind a similar interface. ATSB technical investigators removed conformal coating from the circuit board and removed the flash memory from the circuit board using a hot-air rework station. Talberg says the increasing presence of flash memory devices can have a positive effect on safety, provided they are set to record data. He encourages pilots who carry and use handheld or built-in flash memory equipment to set it up to record flight data. ‘No-one sets out to have a crash, but if the worst does happen, this is a way to help investigators find out what happened - and contribute in a small way to aviation safety,’ he says. Tully says; ‘It goes without saying that ATSB’s assistance is a valuable and integral affiliation that RA-Aus is thankful for. ‘This type of information is invaluable to RA-Aus investigators as it can add a major piece to the accident puzzle.’ The investigators practised on a sample circuit board provided by the manufacturer before attempting the operation. On 2 May 2011, they successfully recovered binary data from the flash memory. The data allowed conclusions to be drawn about engine rpm, manifold pressure and throttle position during the Spitfire’s final flight, which it logged at 16 minutes and 44 seconds. This information has been sent to the Queensland state coroner. 41 42 AIRWORTHINESS Pull-out section APPROVED AIRWORTHINESS DIRECTIVES ...

There are currently over 400 registered (but not necessarily active) hot air balloons in Australia, mostly flying along the east coast, with a few in Western Australia and South Australia. These balloons operate under two distinct Australian organisations: the sport balloonists (represented by the Australian Ballooning Federation [ABF]); and commercial balloonists, (represented by the Professional Ballooning Association of Australia [PBAA]). About 230 of Australia’s 400-plus balloons belong to the ABF’s 290-or-so members, who fly over 1100 hours annually. There are about 30 commercial operators in Australia, most of whom belong to the PBAA. Together these commercial operators fly for about 10,000 hours and carry 150–200,000 fare-paying passengers annually. The larger commercial balloons can carry up to 24 passengers in ideal conditions. Balloons in Australia range in size from 19,000 to 450,000 cubic feet, and can be up to 130 feet tall. Generally, sport balloons are smaller and less expensive than those operated commercially. Sport balloons are not permitted to carry farepaying passengers. Australia has a significant record in international competition and achievement, per capita and size, in comparison to the rest of the ballooning world. Where do they fly? Recreational balloons cannot operate in controlled airspace (unless authorised by CASA), but can access registered aerodromes, as long as they carry and use radios and transponders, as appropriate. They usually fly below 3,000 feet, but the current Australian (hot air) altitude record is 37,839 feet (11,533 metres), and the world (gas) altitude record 113,740 feet (34,668 metres). When flying over populated areas balloons currently must be at or above 1,000 feet above ground level, but this is about to change to 500 feet. Photos 1-5, 7-8: courtesy of Andrew Chapman, photo 6, courtesy of Paul Gibbs Balloons tend to fly in the early morning to take advantage of decoupled catabatic or drainage winds, temperature inversions and stable atmospheric conditions. Experienced balloon pilots have an impressive knowledge and understanding of micrometeorology and regularly navigate their aircraft to exact predetermined points. Balloons travel with the wind, and vertical control is extremely precise. Nine fare-paying passenger balloons recently flew from Bundoora in Victoria to Moorabbin aerodrome and landed, as pre-arranged, between the runways. Equipment carried Altimeter, variometer, envelope temperature indicator, timepiece, compass, fire extinguisher, ground handling drop line, GPS, UHF air-to-ground radio, VHF radio, and transponder where required. There is no air speed indicator because there is no airspeed in a balloon. Licensing Recreational or sport ballooning refers to pilots who hold a private balloon certificate issued by the Australian Ballooning Federation and who do not carry fare-paying passengers. The ABF is responsible for the day-to-day administration of recreational ballooning in Australia, and under arrangements with CASA, carries out safety and surveillance duties. These include: Safety issues Landowner relations Production of operations manual Training and issuing certificates for pilots, instructors and examiners The Professional Balloon Association of Australia has three classes of membership: AOC holders, commercial pilots and associates (manufacturers, maintainers, legal and insurance advisors etc.) Some commercial operators run training courses for aspiring commercial pilots. For a private licence from a zero hours starting point, you need about two weeks, during which you would have a minimum of 16 hours flight instruction and, provided your progress is satisfactory, a flight test. An Australian commercial licence requires a minimum of Flight Safety Australia Issue 85 March-April 2012 75 hours flying experience plus eight hours of advanced training. Australian licences are much respected (and sought after) in commercial operations internationally. This may partly be due to ballooning being taken up by people who are already involved in other forms of aviation, but also because licensing here is taken more seriously by operators and the regulator than in many other nations around the world. Sharing the skies with … balloons Balloons are very visible and move very slowly. If an aircraft comes out of cloud and sees them, it will be easier for it to avoid them than vice versa. Balloon envelopes are made in contrasting colours, to help others to see them even better. Below 500 feet, balloonists exercise extreme caution, care and vigilance. They always do downwind landings. They do not do circuits on landing. They carry and use radios and transponders, as required. Please keep in touch. Balloons are registered and subject to regular airworthiness checks and maintenance. Optical illusions can make balloons look closer and higher than they actually are. Balloons have been reported to be in one location, but tracked on radar somewhere quite different. They are courteous and polite to land occupiers and respectful of landowners’ rights, and make reasonable efforts to obtain permission prior to entering private property. They leave launch and landing areas in the same condition as they found them, with gates, fences and locks as they were. They fly in a manner that does not unduly disturb residents or animals. They always ascertain the location and dimensions of, and any restrictions associated with, sensitive zones prior to flying. They avoid known sensitive zones, and communicate information about new or changed sensitive zones to all other pilots and operators. Safety and balloons Australia’s last hot air ballooning fatalities were in 1989. In October of that year, four people were killed in two separate accidents (both involving wirestrike), and earlier in 1989, 13 people died near Alice Springs in a mid-air involving two balloons. The chief pilot and flying instructor at Brisbane Hot Air Ballooning, Steve Griffin, was quoted in The Sydney Morning Herald in January 2012 as saying most power line incidents occurred in good weather, ‘when people were relaxed and the flight was going beautifully. ‘It’s very important that when conditions are very benign you don’t let your guard down, because that’s when these types of incidents tend to happen and they happen to pilots of all levels of experience.’ CASA has developed draft guidelines requiring commercial balloon operations to implement a safety management system that includes low-flying procedures. The new rules will be released for public comment later in 2012. CASA has also advised the ABF on developing a coordinated training package Cost of ballooning for instructors. A complete type-certified Damian Croc, chief executive sport balloon for private of Professional Ballooning operators, with two to Association, quoted in four people on board January 2012 in a WA regional (POB),costs $50–70,000 newspaper, said Australia had new, or around $20,000 an exemplary ballooning safety for a good second-hand record. ‘Australian commercial aircraft.

CAO 95.54 45 46 CLOSE CALLS Scud running In the late 80s I was working at a flying school in Parafield, as a junior grade 3 instructor – the lowliest of the staff – building my hours and experience in the way everybody seems to have to. It was my first job since obtaining my rating, and at first I was grateful - there were plenty of aircraft and students, and the weather was generally excellent. What more could I want? Well pay, for one thing. Sadly, this was in short supply as I was only paid for flight time – no retainer, and no briefing – and was expected to be available seven days a week and 24 hours a day (how I ran my logbook was my business I was told!). I did what I was told, when I was told, and accepted the instructions of my boss. This was almost my downfall one day, when I was tasked with a two-hour navex with a student in one of the Cessna 172s we had on line. It was to be part of a multi-aircraft exercise, where three students would fly the same basic route, leaving at 10-minute intervals, with the middle aircraft (mine) doing the route in reverse. Normally, this would have been fine, and it wasn’t the first time I’d done this, but the weather was deteriorating, and the forecast was for low cloud and rain, just when I would be trying to come back in over the Adelaide hills via the lane of entry. As it was, much of the route would need to be flown at low level, as the pre-frontal Scud running A junior instructor does as he is told and lives to regret his über obedience Name withheld by request cloud was already down to 2-3000 feet. The aircraft departing before and after me were planned to fly initially out to the east, and then track northwards, eventually completing a huge loop – almost up to Port Pirie – and returning to Parafield via the coastal training areas. This would have them potentially scud running along the coast, but that was much more acceptable than trying to come in over the ranges with the same cloud base – the path I was assigned. I was concerned about this and approached the chief flying instructor suggesting that I too should take the anti-clockwise route. It wouldn’t have been any problem to replan, and the student was already working on that anyway. He wouldn’t give me a reason, just a firm ‘no’. This was not what I’d anticipated, but I was just the junior, so my student and I dutifully boarded our trusty steed and departed. The navex went quite well for the first forty minutes or so, as we flew along the coast past Dublin and Long Plains, and then across to Clare and Burra before turning southwards for the lane of entry and then Parafield. All the way, I was monitoring the developing weather, and eventually decided that I needed to cut the navex short, so had my student divert as early as possible and track around the Edinburgh control zone and training areas so that we could arrive at South Para reservoir Flight Safety Australia Issue 85 March-April 2012 in a timely fashion. In spite of this, we found that the low cloud and rain had beaten us there and we were now – as predicted – stuck on the wrong side of the ranges. Since there was clearly no way we could get through the lane of entry, we continued southbound in the forlorn hope that the weather might improve sufficiently to allow a VFR transit of Adelaide’s control zone and back to Parafield that way. We got all the way to Murray Bridge without a single opportunity to cross the ranges. Eventually, we turned northwards again and found ourselves about 35 miles northeast of South Para, with nowhere else to go. Our options were now limited, and for a while it looked as if we might have to divert to Waikerie or Renmark to land, leaving us without transport, or funds, in a remote airfield on a Friday afternoon! Not a particularly inviting prospect, but one we had to consider. The other option was to call Adelaide Approach and ask for a low-level transit of Edinburgh’s control zone to arrive into Parafield from the north. We did this, and after a little dodging around low cloud, managed to weave our way overhead Edinburgh. I had also dialled up the NDB as additional navigational assistance, but insisted that my student maintain visual contact with the ground, even if we got a little low. Otherwise, we would turn around and head back for Waikerie. Just north of Edinburgh, we encountered a very low band of cloud – around 300 feet – but it was only narrow. The visibility below it was good enough to see Parafield, so we continued, calling visual with the airfield and being transferred to the tower frequency. We flew a normal, low-level circuit, followed by a very welcome landing. Home at last. Needless to say, the other two aircraft were already parked and everybody had gone home for the weekend. Even the CFI had departed – even though I still required direct supervision as a junior. Thanks a lot boss! My student and I put the aeroplane to bed, and I sent him home after a thorough debrief. Once alone, I took out an incident report form, and documented everything for the (then) DoT examiner who was likely to require some answers. I placed the completed form on the boss’s desk and went home. Next morning, I got a very irate phone call from him, telling me that it was none of the DoT’s business, and that he would not be submitting the report as he didn’t need the interference that would result. It was interesting to see his attitude, as I had been told when I joined the company that ‘we do things the right way – no exceptions!’ I phoned the local inspector to talk over the situation anyway. He was concerned about the attitude of my boss, but together we worked out that I had acted appropriately in the end, even though I should never have departed Parafield in the first place. I had learned several very valuable lessons that day: 1. Even though you may be junior in experience, you must use that experience and your judgement to keep you out of situations that could ultimately be dangerous or difficult to recover from. Always leave yourself an escape route, or plan for an early termination of the flight – even if it means you have to wait it out a long way from home. 2. Never be frightened to stand up for what you believe to be the right course of action. If it doesn’t feel right, it probably isn’t right! Don’t be bullied by superiors or peers into doing something you know to be foolhardy, wrong or illegal. (See rule number 1) 3. Having found yourself in a difficult situation, never give up. Work carefully and find the best solution, and don’t be afraid to ask for help from the air traffic controllers. They don’t want you in trouble any more than you do, so they will work with you. 4. Don’t be afraid to own up to the authorities if you feel the safety of the flight was in doubt, or you broke some rules. Generally, you will find a willing listener, and sage advice. You may still be punished or cautioned, but it will be worse if they have to come looking for you! 5. Embarrassment – contrary to popular belief – is not fatal. Foolhardiness however, can be. 47 Born toFl y 48 CLOSE CALLS Born to fly Name withheld by request Experience and recency: fuelling the debate After a few precious and very nerve-wracking seconds we managed to land smoothly and safely before we taxied off the active runway. We came to a complete stop, breathed a sigh of relief and my instructor began to examine the cockpit. After a few moments he stopped and stared, his head looking down at the fuel valve and his eyes wide open. ‘The fuel valve is off!’ The gentle hum of the large turbo jet engines nursed me to sleep on my way back to Hong Kong. I was one month old in my first log book entry and my father, a Cathay Pacific captain, was proudly bringing me home on my first flight from Brussels, Belgium, arriving in Kai Tak at precisely 0115 on 27 Oct 1984. I know that he was already hoping I would become a pilot like him some day. Analysis Twenty-three years later I found myself working towards my private pilot licence. I was sitting in the left seat of a Cessna 172, a bit nervous, but very excited about my first flight in this new type after graduating from the Cessna 152. The dangers of flying a new type of aircraft are found in unexpected places. Thanks to standardisation of instrument cluster layouts and engine control levers, some of the traps and confusions are gradually being eliminated. I began to go through the checklists and asked my instructor if the fuel switch was in the on position. After a quick glance and an ‘OK’ from him, we completed the rest of our checks and taxied down the runway for the pre-flight take-off checks. I took another quick glance at the fuel valve and all was looking good to go for my first flight as pilot in a C172. In this case the fuel valve on a C172 is quite different to that on a C152. The rotary type of valve on the C172 can be selected to left, right, off, or both tanks, with no separate off switch in earlier models. It had been six months since my last flight, and I caught myself trying to remember all the important safety steps. The run-up checks say that the fuel valve should to be set to ‘both tanks’. The valve is similar looking to a pool pump valve lever, which I had used only a few days earlier while doing routine pool maintenance at our house. Perhaps my familiarity with this system had affected my judgement as to where the lever should be positioned for the selection desired. I have since learned that a C172 is nothing like a pool pump, even though it had me swimming in my own juices. My head was full of V speeds for this first C172 flight. At that early point in my career I also knew I wasn’t familiar enough with the sound of the engine, or how the aircraft was handling to diagnose any problems. We finished our pre-flight take-off checks and began to line up for the take-off. I started to give the aircraft more power as we rolled down the runway. So many things were running through my head, Ts Ps green, airspeed live, no fire. Everything was looking good as we lifted off the ground, but, without any warning, the engine started to sputter and cough. Before I knew what was happening my instructor cut in and said ‘I have control’. I replied ‘You have control’ and he began to turn us around in preparation for an immediate landing. The tension was clear, and I could tell by the sound of his voice that we were not safe, as he alerted the tower to our return for a low-level circuit for immediate landing. That fear in his voice was nothing compared to the sound our engine was making as we began our descent, and prepared for our emergency landing. The C152 fuel switch is much simpler, with just an option for on or off. I set the C172’s valve to what I thought was both tanks. I had my doubts and because I had never operated this system before I asked my instructor whether I had indeed switched the valve to the on position. He glanced down and nodded in acknowledgement. He might have misheard my question and probably didn’t imagine that anybody could make a mistake with such a simple system. He might have also not realised how confusing a fuel valve could be to someone who had just graduated from the C172’s little brother, which was almost identical in operation. Further research has shown that I am only one of many who have fallen into this trap. Flight Safety Australia Issue 85 March-April 2012 After a few moments he stopped and stared, his head looking down at the fuel valve and his eyes wide open. In run-up and pre-take-off checks we both glanced down and saw what we thought was a fuel gauge set to ‘both tanks’. We had checked this valve three times and seen ‘off’ without realising it. If our subconscious had a voice it would have been screaming ‘ Look! It’s off!’ The aircraft took off and climbed to about 300ft before it protested that it was starving. How could we have done all our checks, taxied all the way across the airport and taken off without any fuel being fed to the engine? ‘The fuel valve is off!’ Instructor-student trust is important so that the student can gain confidence and autonomy in their flying. Too much trust can cause dangerous situations, as we both found out. Also, trusting your instructor to know everything about you and your level of knowledge can create potential crises. My lack of knowledge of the fuel system could have been our downfall, as I had spent all my study time learning the C172’s limitations, speeds and procedures. My questions should not have been ‘is the fuel on?’ but rather, ‘ - how do I operate the fuel system?’ which would have necessitated a full answer with undivided attention rather than a quick nod. People have told me since that this is an impossible situation, but the aircraft had just been fully fuelled and must have had enough fuel in her lines to take us up and very quickly back down again. If the fuel had been exhausted just seconds later we would have been over factories and houses with very limited landing options, if any. It is lucky in a way that the active runway was so far from our starting point, and that our engine starting quitting when it did. My instructor was very quick to recognise the problem and immediately acknowledged the need to land as quickly as possible. My flying instincts had become dormant in the months preceding the flight and I was not able to recognise the problem as rapidly as he did – a wake-up call about the importance of experience and recency to safe flying.

In that split second he had suffered deep cuts to four fingers on his right hand. I was 18-years-old, and each day I drove past the airport heading to work. From the road you can see the hangars and the aircraft parked on the apron, with at least two or three aircraft flying circuits above. Sometimes I counted up to six aircraft, sometimes more. My birthday was a few months away. What better present to give myself than flying lessons? The following weekend I went to the airport, where in those days every second building housed a flying school. For no particular reason I chose a school that used Beechcraft Sundowners–four-seat, low-wing, fixed undercarriage, with a Lycoming 0-360 engine. The staff were friendly, and after a brief chat, we scheduled a trial instructional flight for the next day. Less than 24 hours later, I was back at the school meeting the instructor who would take me for the flight, and just minutes after I was airborne and heading towards the local training area. Yes, I thought, this is definitely for me. In the next few weeks I attended the necessary aviation medical, filled in forms, bought text books and booked my first lesson. Then the morning arrived. The weather was calm, blue sky, and a mild temperature for that time of the year. It looked like a great day for flying. I was scheduled for the first lesson of the day and it was the first time that day the aircraft would be used. I met my instructor and we had a pre-flight briefing. Then it was out to the aircraft, where I was shown how to perform the preflight inspection and check the fuel for water. My anticipation and excitement were growing with every passing minute. Finally we climbed into the aircraft and I sat in the left seat. We made ourselves comfortable, adjusting seats and seatbelts. My instructor then commenced the start-up procedure, while talking me through it. I sat as an interested observer taking in as much as I could. Flight Safety Australia Issue 85 March-April 2012 Everything was going to plan. My instructor flicked the master switch on and turned the key. I expected the dials to come alive, lights flash and the engine burst into life, but nothing happened. Everything was quiet and the dials were still. No response from the aircraft at all … silence. ‘Dead battery’, said the instructor. My anticipation and excitement evaporated in an instant. Just as he spoke, another aircraft from the school was taxiing into a parking position close to our aircraft. Its pilot was a student who was about to obtain his PPL. My instructor then said, ‘I will show you how to hand start an aircraft’, and called the other student pilot over. He explained the dead battery situation and his intentions to hand start the aircraft and asked for help to start our disabled aircraft. I was now an interested spectator with absolutely no idea of what was about to occur. The student pilot sat in the aircraft and instructor gave him instructions about the start-up procedure. The instructor stood directly in front of the aircraft, grabbed hold of the propeller blade on his left-hand side and proceeded to turn the propeller several revolutions opposite to its normal direction. He gave more instructions to the student pilot in the aircraft and then, with his right hand, pulled down forcefully on the right propeller blade in the normal direction. The propeller turned and the engine coughed briefly but did not start. More instructions to the student pilot, and the process was repeated. The instructor performed his previous procedure of turning the propeller in the opposite direction, then grabbing the right-hand blade of the propeller with his right hand and forcefully pulling down on it. What happened next took place in a split second at high speed. When the propeller blade was at about four o’clock, the engine spluttered then backfired, and the propeller blade went in the opposite direction to the instructor’s forceful pull. The suddenness and speed of this change of direction caught him completely by surprise and he was still hanging onto the leading edge of the propeller. His arm extended upwards and he only managed to release his hand when he appeared to be at full stretch. He was still able to stand, but was pale and slumped over, grabbing at his bleeding right hand with his left one and grimacing in intense pain. In that split second he had suffered deep cuts to four fingers on his right hand. His right arm was hanging limp and he said he thought that his arm was broken, indicating an area close to the shoulder. Blood was dripping through his fingers onto the tarmac and his pain level appeared to increase. He did remain conscious and was able to make his way to the office some 25 metres away with the assistance of the student pilot. The staff gave him first aid help and an ambulance was called. I stayed with the aircraft until another instructor came over to lock it up. Needless to say, my lesson and the instructor’s other lessons for that day were cancelled. This incident certainly did not put me off learning to fly, or off that flying school. My first lesson was rescheduled for the following week with another instructor, who turned out to be the CFI. I never saw the injured instructor again and the incident wasn’t discussed with me or ever spoken about again. I have often wondered why the instructor decided to show a brand-new student a complicated, high-risk, dangerous procedure that had claimed many victims. Why didn’t he just ask the LAMEs who shared the school’s hangar to investigate the flat battery?

To help us do our safety job in aviation, we are also the notification point for all aviation safety occurrences in Australia. This means that whenever there’s an aviation incident or accident—no matter how seemingly minor—you should notify us. We use this information in two ways: to decide whether to investigate an occurrence; and to make real practical improvements to aviation safety. The data we get from notifications helps us analyse trends, find patterns in aviation safety and alert the relevant people to any ongoing problem or risk. But to do this effectively, we need to be told about these occurrences. This is where we rely on the people at the fore of the aviation industry: the operators, pilots, engineers, and safety managers. Besides being a legal requirement, your notification to the ATSB is invaluable to helping prevent another accident. Ultimately your notification could save a life. If you’re not sure if an incident or accident is ‘notifiable’, the best rule of thumb is to report it to the ATSB anyway. That includes recreational and sports aviation as well. We know that people are generally pretty good at reporting already. But it could be even better. One example: we’ll soon be publishing a safety investigation report that reveals that at least 40 per cent of aviation wirestrikes are not reported to the ATSB. This is a startling find and we strongly encourage everyone involved in a wirestrike to tell us about it. We’re currently finalising some changes to the rules for notification to make them clearer and simpler. In the meantime, you can find more information on the notifications process by calling 1800 011 034 or by clicking the ‘Submit a mandatory accident or incident notification’ icon on the ATSB website www.atsb.gov.au.

An avoidable tragedy A fatal helicopter accident in the Northern Territory has highlighted the importance of pilots and operators using consistent, reliable procedures to independently verify the fuel quantity in their aircraft’s tanks. On 4 October 2010, the pilot of a Robinson Helicopter R22 Beta was mustering cattle on a station property about 170 km east of Katherine, NT. When the station owner was unable to make radio contact with the pilot he immediately conducted an aerial search. The search found that the helicopter had crashed heavily into the ground and the pilot did not survive the impact. The ATSB’s investigation found that the helicopter’s engine had stopped while operating at low altitude. The cause of the engine stoppage was most likely due to fuel exhaustion, which happens when there is insufficient useable fuel to supply the engine. To maximise the performance of the R22 during mustering, the station’s pilots generally minimised the helicopter’s weight by only uplifting enough fuel for the expected duration of the flight. If the pilot took off with less than a full tank of fuel he may have thought that there was more fuel on board the helicopter than was actually the case. Accident site of VH-THI On the day of the accident, neither the fuel uplifted and consumed, nor the flight time was formally recorded by the station pilots. Safe flight depends on reliable power Fuel exhaustion and fuel starvation are the two main reasons for the interruption of fuel supply. Fuel exhaustion and starvation incidents and accidents have led to forced landings, diversions to other aerodromes and, in the worst cases, fatal crashes. And it’s not just single pilot operations that are at risk—all pilots, including those flying with multiple crew, are vulnerable to human error and its consequences. The ATSB urges all pilots and operators to review their fuel management practices and procedures to ensure they are effective, consistent and reliable. The ATSB’s latest Avoidable Accident report, Starved and exhausted: Fuel management aviation accidents, helps pilots and operators better understand and manage the risk of fuel exhaustion and starvation. You can download the report free of charge from the Safety Awareness section at www.atsb.gov.au or request printed copies by emailing [email protected] ■ Preventing fuel exhaustion and starvation Poor fuel management in some aircraft operations continues to pose a serious risk to aviation safety. Fuel exhaustion Many accidents involving fuel exhaustion and starvation are avoidable through good fuel management practices and procedures. Pilots and operators can reduce the chance of fuel exhaustion by: • using more than one source of information to obtain consistent results about the fuel on board before flight • implementing a consistent procedure, and checking it regularly, to establish and monitor the exact rate of fuel consumption • monitoring the flight to ensure that sufficient fuel will remain on board in the event of unplanned delays. Fuel starvation Fuel starvation usually happens when the selected tank is run dry. The chance of fuel starvation can be reduced by following procedures and by: • ensuring the pilot is familiar with the operation of their aircraft’s fuel system during normal and abnormal operations • adhering to pre-flight procedures and checks to ensure the correct tank is selected before takeoff and landing • using a fuel log during flight to provide a record of the fuel usage from each tank • selecting the appropriate tank before descending and ensuring it has adequate fuel for landing. ■ Your notification improves safety, saves lives I f you were involved in a serious car accident, one of the first things you’d do is alert the authorities (if you were able to do so).

In response to Safety Advisory Notice AO-2009-044-SAN-068 (Flight Safety Australia Issue 84) the ATSB has had a number of requests from operators to help locate vendors of alarm systems. While not endorsing any particular product, the ATSB is aware of the following suppliers: Unrecognised hypoxia in an unpressurised cabin continues to pose a serious safety threat. In many cases, pilots have either not noticed existing visual warning systems, or those systems failed to operate correctly. Electric Force Measurement P: 03 9859 8356 W: www.electricforcemeasurement.com.au Audible warning systems provide a voice prompt warning through the aircraft’s cockpit speakers and the pilot’s headset.

On 24 April 2011, the owner-pilot of a Robinson R44 helicopter departed Nerrigundah, with one passenger on board, for a private flight to a property near Berry, NSW. Takeoff was delayed and by the time the flight departed, there was not enough daylight left for the pilot to complete the flight under the day visual flight rules. During the flight, the pilot observed cloud, moderate rain and low visibility along the planned track and decided to divert to a private helicopter landing site to maintain visual meteorological conditions. The pilot reduced airspeed and descended over water to what he believed to be 100 feet. Now flying in darkness, the pilot lost visual reference and the helicopter collided with the sea in Lilli Pilli Bay. The pilot survived and the passenger was fatally injured. The safety lessons from this accident have relevance to every flight: • pre-flight preparation and planning is vital • always check the weather forecast and other operational details before takeoff and in-flight • have a backup plan and be prepared to use it • make decisions early—if there’s any doubt, turn about. The booklet Accidents involving Visual Flight Rules pilots in Instrument Meteorological Conditions and investigation report AO-2011-051 are available on the ATSB website at www.atsb.gov.au ■ Recording service life in overweight operations PT6A-67 series engine bolt failure Investigation AO-2008-084 Investigation AO-2010-006 On 29 December 2008 the pilot of a PZL-M18A Dromader aircraft was conducting agricultural spraying near Nyngan NSW. Witnesses reported seeing something detach from the aircraft before it rolled and crashed into the ground. The pilot was killed in the accident. The ATSB’s investigation found that during the flight a 1.8 metre section of the aircraft’s right wing had detached from the aircraft. Bolts that had not been cold rolled during manufacture and overhaul on PT6A-67 series engines caused total power loss for the pilot of a medical evacuation flight in WA. While not directly related to the inflight breakup the ATSB also identified that a number of operators of PZL-M18 Dromader aircraft were not calculating the correct flying hours when the take-off weight was over 4,700 kilograms. That resulted in the overestimation of those aircrafts’ remaining service life and meant that it could not be assured that they were being operated within their safe service life. The investigation has prompted the following safety actions: • the operator examined its fleet and retrospectively applied the correct service life factors and adjusted their processes to apply correct service life factors to all future flights • CASA contacted operators of M18 Dromader aircraft to ensure that procedures are in place to record aircraft time-in-service for overweight operations and that overweight flight time is factored into the calculation of Dromader airframe service life. The final report is available on the ATSB website at www.atsb.gov.au ■ On 29 January 2010, during a flight in a single-engine Pilatus PC-12/45 aircraft with four people on board, the pilot felt a shudder and heard a loud noise as the aircraft passed through flight level 180. Subsequently, the engine CHIP light illuminated indicating the detection of metal chips in the engine oil. The pilot continued the climb and immediately turned back towards Derby. The engine lost oil pressure, engine torque decreased and the inter-turbine temperature increased. The aircraft’s rate of climb began to reduce and the pilot established into level flight before further reducing engine power. The pilot shut down the engine when the OIL QTY warning light came on. The ATSB’s investigation found that the engine propeller reduction gearbox had seized when four of the six reduction gear assembly carrier bolts failed due to fatigue. The engine manufacturer determined that a quantity of assembly carrier bolts had not undergone the necessary cold rolling during manufacture. Service bulletins were issued that identified affected gearboxes and provided recommended compliance times for the removal from service of suspect carrier bolts. The investigation also found that the Society of Automotive Engineers specification AS7477D was ambiguous in relation to the need to cold roll the headto-shank fillet radius of MS9490-34 carrier bolts. The Society published a revised specification in October 2011, clarifying the need for cold rolling of those bolts. The final report is available on the ATSB website at www.atsb.gov.au ■ REPCON briefs Australia’s voluntary confidential aviation reporting scheme REPCON allows any person who has an aviation safety concern to report it to the ATSB confidentially. All personal information regarding any individual (either the reporter or any person referred to in the report) remains strictly confidential, unless permission is given by the subject of the information. The goals of the scheme are to increase awareness of safety issues and to encourage safety action by those best placed to respond to safety concerns. REPCON would like to hear from you if you have experienced a ‘close call’ and think others may benefit from the lessons you have learnt. These reports can serve as a powerful reminder that, despite the best of intentions, well-trained people are still capable of making mistakes. The stories arising from these reports may serve to reinforce the message that we must remain vigilant to ensure the ongoing safety of ourselves and others. New company procedure Report narrative: The reporter expressed safety concerns over a new procedure being trialled at Sydney Airport which involves taxiing the aircraft to the arrival gate without starting the auxiliary power unit (APU). The new procedure requires flight crew to listen to both company radio frequency as well as the ground frequency after landing, to monitor the status of ground power serviceability. Both these frequencies are reported to get very busy at this airport. The reporter is concerned that there is an increased risk of a runway incident with this increase in monitoring workload. Response/s received: REPCON supplied the operator with the de-identified report. The following is a version of their response: A limited trial associated with APU management is being conducted. The purpose of the trial is to quantify the benefits and identify any issues associated with the APU management procedure. Based on feedback from flight crew and review during the trial period, the requirement to monitor the company radio frequency for this procedure has since been removed. ATSB comment: Two days after the de-identified report was sent to the operator, the reporter advised REPCON that the requirement to monitor both company and ground frequencies was removed from the new procedure. The operator also advised that since their previous response, the procedure to taxi to the arrival gate without starting the APU was cancelled after four weeks of trials. Now the APU is kept running to the gate and there is no need for monitoring of additional frequencies for this purpose. Flight crew and cabin crew fatigue Report narrative: The reporter expressed a safety concern regarding the increase in fatigue levels in both flight and cabin crew members. The reporter stated that it is common for crew members to be rostered on for the maximum duty time, but in reality this means that the crews will have to extend due to normal delays. It is expected that crews will be ‘happy’ to extend their duty to complete the flight. The reporter also stated that the work load is increasing constantly with a trend for 6-day weeks, multiple sector days, long duties and extensions appearing. The operator is currently using the dispensation to Civil Aviation Order (CAO) 48 to the maximum extent, with the result being an increase in crew fatigue levels. Response/s received: REPCON supplied the operator with the de-identified report. The following is a version of their response: I have carried out a random audit of our fatigue management system and Flight and Duty times recorded and rostered. My findings are as follows: • The average 14 day duty cycle for the High Capacity crews are ranging from 60 – 85 hours well within the 100 hour limit. It is very rare for a crew member to have cumulative duty in excess of 90 hours on this fleet. • The average 14 day duty cycle on the Low Capacity is approximately 75 hours. • We do fly seven days per week although there is only one scheduled flight on Saturdays and one scheduled flight on Sundays. Crews very rarely do a weekend flight on subsequent weekends. • The Flight and Duty exemption restrictions are adhered to at all times. I have reinforced to crews that fatigue management is both the pilot’s and the company’s responsibility and if a flight crew member is not adequately rested and in a physically and mentally fit state to fly, then they must inform their fleet manager or myself who will remove them from the roster. Operations do not expect pilots to automatically accept duty extensions. It is, and always has been, the decision of the pilot to extend a duty in accordance with the fatigue management system. I do not believe the author is correct in his observations. REPCON supplied CASA with the de-identified report and a version of the operator’s response. The following is a version of the response that CASA provided: This matter has been reviewed by CASA with the operator’s Chief Pilot. CASA is satisfied with the operator’s response and its internal investigation. ■ How can I report to REPCON?

The 50 occupants in the aircraft, and one person in the house, were killed. Although light snow was falling, night VFR conditions prevailed at the time.The twelfth day of February 2009 was a rotten day for flying in the northwest United States. A 74-seat, Bombardier Q400, owned by Colgan Air of Newark, New Jersey, was operating a daily commuter flight to Buffalo in New York State, under contract to Continental Airlines but the crew’s first two scheduled flights for the day had been cancelled because of high winds. Their planned departure for Buffalo was now 7.10pm, with an estimated flight time of 53 minutes, cruising at 16,000 feet. Flight Safety Australia Issue 85 March-April 2012 But, as often happens after a long day of dirty weather in crowded airspace, taxi clearance was delayed. The 50 people on board had to wait in the aircraft until 8.30pm. At 10.12pm, the controller cleared them to descend and maintain 2300 feet but, as they followed ATC’s instructions, they continued their conversation. The first officer was not feeling well. Suffering from a cold and sneezing, she remarked to the captain as they were taxiing, ‘I’m ready to be in the hotel room … we’ll see how it feels flying’. Less than three miles from the outer marker, the captain reduced engine power to minimum thrust to slow the aircraft for final approach, and the controller instructed them to call the tower. The first officer’s acknowledgement was the last transmission from the aircraft. The tower cleared the aircraft for take off at 9.18pm, the captain indicating he would fly the leg himself. During the climb to cruising level, with the weather typical of winter, the crew turned on the propeller and airframe de-icing equipment. They also engaged the autopilot. The cruise was uneventful, and although the crew engaged almost continuously in conversation, they did not at this stage contravene the sterile cockpit rule. At 9.50pm, the first officer reported the wind at Buffalo was from 250° at 15 knots, gusting to 23 knots, and the captain said they would use runway 23. The first officer briefed the airspeeds for landing, with flaps 15 as 118 knots for their reference landing speed, and 114 knots for go-around speed. The first officer said it might be easier on her ears ‘if we start going down sooner’, and the captain told her to ‘get discretion to 12,000 feet.’ Cleveland ATC cleared them to descend to 11,000 feet, and instructed them to contact Buffalo approach control. The captain began the approach briefing, but was interrupted by the controller clearing them to descend and maintain 6000 feet. Resuming, the captain repeated the airspeeds the first officer announced for a flaps 15 landing. The aircraft descended through 10,000 feet; from that point, the crew was required to observe the sterile cockpit rule. After approach control cleared the aircraft to descend and maintain 4000 feet, the captain asked the first officer how her ears were. She said they were ‘stuffy’ and ‘popping’ and asked him if ice was accumulating on his side of the windscreen. He replied that it was. She told him her side had, ‘lots of ice,’ and the captain said, ‘That’s the most ice I’ve seen on the leading edges in a long time.’ The first officer commented she had accumulated more flight time in icing conditions in her first days of experience with Colgan Air than she had before she joined the company. She also remarked that she ‘wouldn’t mind going through a winter in the north-east before becoming a captain.’ Before she joined the company, she explained, she had ‘never seen icing conditions … never de-iced … never experienced any of that.’ The crew extended the undercarriage, and advanced the propeller levers to maximum rpm. The autopilot applied noseup pitch trim, and the airspeed decreased to 145 knots. As the autopilot applied more nose-up pitch trim, an ‘ice detected’ message appeared on the cockpit engine display. At almost the same time, the captain called for flaps 15 and for the prelanding checklist. The first officer selected the flaps to 10°, and the airspeed fell to 135 knots, but suddenly the stick shaker activated and the autopilot disconnect horn began sounding. Caught completely by surprise, the captain began wrestling with the control column, at the same time advancing the engine power levers to about 70 per cent. With the airspeed at 131 knots when the autopilot disengaged, the aircraft pitched up sharply as the engine power responded, rolled left 45°, and then rolled right. As it did so, the stick pusher attempted to lower the nose, but the captain fought its action. On her own initiative, the first officer selected flaps up. The airspeed fell to about 100 knots, and the right roll reached 105° before the aircraft began rolling back to the left. The stick pusher activated a second time but, now grunting with exertion, the captain continued to fight the nose-down force. From about 25° nose down and banked 100° to the right, the aircraft finally entered a steep descent, and as the flaps became fully retracted, the stick pusher activated a third time. The captain called out, ‘We’re down!’ and a moment later the CVR recorded the noise of impact as the aircraft crashed into the house. Investigation Fourteen investigators from the National Transportation Safety Board were assigned to examine the circumstances of the accident. The aircraft had sheared off the tops of two trees before striking the southern side of the house near ground level, and exploding into flames. Only its empennage remained intact. The captain, aged 47, received his command on the Q400 four months before the accident and three years after joining the company. His total flying experience was around 3400 hours, of which 111 hours were on the Q400. He also had experience on Beech 1900 and Saab 340 aircraft. 59 60 FEATURE Colgan Air crash Flight 3407 Federal Aviation Administration records indicated he had failed flight tests on four occasions during his training. The first officer, 24, had been with the company for a little over a year and had accumulated 2244 hours flying time, including 774 hours on turbine aircraft. She was considered above average for her level of experience. When the crew turned on the de-icing equipment, the captain would also have turned the reference speeds switch on the ice protection panel to the ‘increase’ (icing conditions) position. This would have lowered the angle of attack reference, increasing the speed for activation of the stick shaker by about 15 knots. Although the aircraft did encounter snow and light-to-moderate icing during its approach, and some ice had accumulated on its surfaces, flight recorder data showed it was responding normally and the ice was not affecting the crew’s ability to control the aircraft. But because the reference speeds switch was selected, the aircraft was not close to stalling at the time, and because stick shakers provide a 5-to-7-knot warning of an impending stall, the crew actually had a 20-to-22-knot warning. When the autopilot disconnected as the stick shaker activated, the captain’s response was a heavy pull on the control column. At the same time he added substantial power, causing the aircraft to nose-up sharply. This did produce an aerodynamic stall, with a roll to the left that reached 45°, despite the captain’s opposing control inputs. This was followed by several roll oscillations, during which the captain repeatedly fought the stick pusher’s attempts to lower the nose by pulling back on the control column with forces of up to 160 pounds. Analysis When the controller informed the crew they were three miles from the outer marker and cleared them for the ILS approach, their airspeed of 184 knots was too fast for their position. The captain had to slow the aircraft quickly, probably because, distracted by his conversation, he had lost positional awareness. He did so by extending flaps to 5°, reducing power to near idle, lowering the undercarriage, and moving the condition levers to maximum rpm. Because autopilot altitude hold mode was engaged, the autopilot continued to add nose-up trim to maintain altitude after the aircraft levelled off at 2300 feet. But neither pilot remarked on the increasing pitch, even though it should have indicated that the airspeed was continuing to slow. FAA ILS/LOC approach plate to runway 23 at Buffalo Niagara International Airport (KBUF). The crash site occurred about five nautical miles from the threshold of Rwy 23. Source: Wikimedia In addition to other instrument indications, the numbers on the IAS display changed from white to red as the aircraft reached the higher stick shaker activation speed. The captain had the primary responsibility for monitoring the instruments, with the first officer responsible for providing backup. The investigation believed that explicit cues that the aircraft’s attitude was becoming excessively nose-up and that the onset of the stick shaker was impending, should have been evident in adequate time to take corrective action. But neither pilot responded. Furthermore, the crew failed to consider the position of the reference speeds switch when the stick shaker activated. After the accident, another Colgan crew had a similar experience when the stick shaker activated during a night VMC approach to Buffalo. Again they had forgotten that the reference speeds switch, set to ‘increase’, had raised the stick shaker activation speed, and failed to realise the stall warning was impending. Flight Safety Australia Issue 85 March-April 2012 It was evident that Colgan’s approach procedures for setting airspeed bugs did not adequately remind crews of the reference speeds switch position, creating an opportunity for confusion. When the stick shaker activated, the aircraft was not in an aerodynamic stall, and there was sufficient airspeed to correct the situation, but the captain inexplicably pulled back on the column rather than pushing it forward to reduce the aircraft’s angle of attack. As a result, its airspeed decreased further, and it stalled, and because the airspeed remained low after the stall, the stick shaker remained active. Even though the captain added power in response to the stall warning, he did not add full power as required. The first officer also did not tell him it had not increased to the rating detent, or advance the power to the detent when the captain failed to do so. The captain did not call for the flaps to be retracted, yet about seven seconds after the stick shaker activated, the first officer raised the flaps, only telling the captain afterwards. The investigation was concerned that the captain pulled against the stick pusher three times, and that his control inputs repeatedly fought the stall protection system’s attempts to reduce the severity of the situation. His actions were entirely inconsistent with any procedure or basic requirement for recovering from a stall. Had the captain not overridden the stick pusher, it would have forced the nose of the aircraft down. If the captain had responded correctly to this nose-down input, the aircraft might have recovered flying speed in time to avoid the impact. But the first officer’s raising of the flaps reduced the lift produced by the wings and increased the stalling speed when the aircraft was already stalled. The captain’s response to the stick shaker should have been automatic, but rather than responding from well-learned habit, his reaction was one of surprise and startled confusion, and his control inputs were totally inconsistent with basic flying training. He did not recognise the stick pusher’s action to decrease the aircraft’s angle of attack and his efforts to override it only exacerbated the situation. Although the stall recoveries he had practised did not involve an autopilot disconnect, or an element of surprise, his experience should have allowed him to react correctly. His history of failure during training showed weaknesses throughout his career with instrument flying, with heavy reliance on autopilots, and this could have contributed to his deficient performance. Research has shown it can be difficult for pilots to recognise and recover from quite unexpected unusual attitudes, and the poor night visibility at the time precluded any reliable visual reference. Also, the aircraft’s G loadings and its proximity to the ground would have increased the stress of the moment. Fatigue might also have been a contributing factor. Both pilots lived a long distance from Newark and regularly commuted by airline from their homes for their tours of duty. Both had been at Newark Airport overnight and all day before their 9.18pm departure, without adequate rest facilities. Reasons for incorrect recovery procedures Did the captain respond incorrectly to the stick shaker because he was applying techniques appropriate to a tailplane stall? Both the captain and the first officer had watched a NASA video on icing that explained that tailplane stalls were most likely with regional and corporate turbo-prop aircraft with ice on the tailplane. The recommended tailplane stall recovery procedure entailed pulling back on the control column and reducing flaps, which the crew did. However, the video also said that typical tailplane icing symptoms were a lightening of control forces, pitch excursions, difficulty in pitch trim, control buffeting, and sudden nose-down pitch, none of which occurred in this case. Furthermore, the stick shaker activation was a clear warning of an impending conventional stall, not a tailplane stall, and the change in the IAS numbers to red was a conspicuous signal inconsistent with a tailplane stall. Flight management Although the captain was responsible for managing the flight, he and the first officer engaged in irrelevant conversation throughout much of it. During cruise this did not conflict with regulations or company policy, but probably contributed to delays in performing checklists. Once the aircraft had descended through 10,000 feet, sterile cockpit procedures should have been observed. They were not, and the crew squandered time that should have been spent monitoring, maintaining situational awareness and preventing errors. Cause The National Transportation Safety Board attributed the accident to the captain’s inappropriate response to the activation of the stick shaker, producing an aerodynamic stall from which the aircraft did not recover. Contributing factors were the crew’s failure to monitor airspeed and adhere to sterile cockpit procedures, the captain’s failure to manage the flight effectively, and Colgan Air’s inadequate procedures for selecting airspeeds during approaches in icing conditions. 61 62 FEATURE Cabin crew training THe cabin cONNECTION Cabin crew members are the eyes and ears of the flight crew. Training them well is vital. Aviation is an information-rich industry and training programs may be the first exposure that aspiring cabin crew members (and their fellow aviation professionals) have to all the safetycritical information that will potentially save their, and others’, lives. Cabin crew members are the eyes and ears of the flight crew. The best available training and regular recurrence, in facilities that allow for realistic simulation of all the emergency situations that might arise (including the occasional dirty nappy scenario) are important in developing competency. Australia has a mandate for annual recurrent testing. Further, all cabin crew instructors must be CASAapproved. The U.S. Federal Aviation Administration (FAA) has encouraged airlines to implement an advanced qualification program (AQP) for flight attendants as ‘an alternative method for developing training and testing materials for …flight attendants… based on instructional systems design, advanced simulation equipment and comprehensive data analysis to continuously validate curriculums’. Jargon aside, the FAA expects this standardisation to ‘require flight attendants to complete hands-on performance drills every 12 months, using emergency equipment and procedures, with trained and qualified flight attendant ground instructors and evaluators’. Bringing cabin and flight crew together in training, assists in ironing out inconsistencies which have arisen in cockpit-cabin communication and coordination, especially in these times of locked flight deck doors. Crew resource management training, and pre-flight briefings that include both pilots and cabin crew, allow the entire team to work together more effectively and safely. What qualities make for the best cabin crew members? Having a cool head under pressure, diplomacy, flexibility, resilience, common sense, the ability to think on your feet, efficiency and time management, good problem-solving abilities, friendly, sociable, able to make conversation easily – and caring. You need to care about your guests, care about your teammates, care about improvement and care about safety! Domestic cabin crewmember and cabin safety officer Exceptional face-to-face customer service, attention to detail, punctuality, sense of humour, real communicator, procedure based, team player, ability to be a quick thinker and follow directions. Team leader, cabin crew training A genuine team player, a skilled follower as well as leader, a clear communicator, considerable patience and understanding of others, strong assertive skills, high emotional and social intelligence, strong time management skills, able to cope with shift work. Safety systems inspector The ideal CCM has that balance of service and safety that allows both elements to be implemented at all times. Cultural issues can crop up from time to time. For example, the cultural backgrounds of some passengers may clash with the background of the CCM. As a stereotype and with my tongue firmly in my cheek, I’d say that the ideal CCM is a waiter in a Michelin-starred restaurant, a clothes hanger in a fashion show, a sheepdog when it’s time to round the passengers up and an old-fashioned drill sergeant in an emergency. Quality and safety manager Photos courtesy of Sue Rice and Emirates Aviation College Flight Safety Australia Issue 85 March-April 2012 What did you learn/wish you had learned in your training? I had mixed emotions about my training. I was very excited and my expectations were high, as it was my first flying job and I was with a large airline. Unfortunately I found that from day one we were treated like children. We were lectured by the trainers, who basically read from the manual word for word. It was death by PowerPoint, and the usual teaching techniques – role plays, group activities and multiple choice exams – were used and overused. Surely there is room for more creative techniques and individuality? It was a six-and-a-half-week course which covered aviation first aid and CPR, fire training, security training, dangerous goods, manual lifting, emergency procedures, standard operating procedures and service. The security training was basic and although I’d love to tell you more, if I did I’d have to kill you. Disappointedly we hardly touched on service, which set no expectations for those new to the company. But after all was said and done, I walked away from my training with a warm feeling of camaraderie and an endorsement on an RPT aircraft. Having said all that I feel lucky that my training was paid for and I was paid during my training. I’ve heard much worse stories. Domestic cabin crew and cabin safety officer I wish that I had been given more practical negotiation tools and strategies to deal with working under pressure within tight timeframes; with different personality types and within the tight commercial pressures versus safety environment.

All Hong Kong Airlines staff have also been invited to undergo training in wing chun – a form of kung fu used in close combat – with compulsory training for cabin crew, as a means of dealing with unruly passengers and even terrorists. The basis of what trainees need to know will always be the SOPs, emergency procedures and crowd control. Their technical knowledge can be quite limited, as long as the basics are addressed e.g. snow and ice contamination on the wing (my airline is in northern Europe). The ability not to show fear and thereby create panic in unusual/emergency situations is important. Equally, pretending that as a CCM you know it all is a bad thing. Years ago, travelling as a passenger, I pointed out to a CCM that the engine’s magnetic chip detector panel door was open and the chip detector was possibly not in (risking total oil loss from that engine). I did this during pushback and just prior to engine start. Her (it was a female CCM) reaction was that it was normal and if the panel was open the flight crew wanted it that way. Her view was that no passenger knew more about the aeroplane than she did. I did eventually convince her - by showing my crew card - to inform the flight deck. Immediate action was taken to put the plug back and shut the panel. In short, she needed to know that if you don’t understand the situation go and ask!

The centre houses two full-motion emergency evacuation cabin simulators – a B777 and an A330/340 – and an A380 full-height static simulator; a ditching platform into a freezing pool; and a purpose-built firefighting facility all for safety and emergency procedures training. A further 14 cabin service simulators, replicating every cabin in the Emirates fleet, form part of the service training equipment, with specialised classrooms for image and uniform, medical and security training, and a Majilis in which students explore and experience the all-important Arabic culture of hospitality. In 2010 the airline carried 31.4 million passengers. Emirates has more than 14,000 cabin crew and will almost double its crew numbers within the next decade. Cabin crew members come from over 130 nationalities and speak over 50 languages, with some individuals speaking three, four and even seven languages fluently! Only five per cent of applicants are selected to commence training. Every Wednesday, up to 120 aspiring cabin crew members arrive in Dubai to begin their ab-initio course. Students complete seven and a half weeks of intensive training and assessment, including induction, safety and emergency procedures, service, image and uniform, aviation medicine, security and CRM, culminating in a simulated flight with unexpected challenges. How do our Gen Y students like to learn? Research states they are socially aware, tolerant, tech savvy, team oriented and good at multi-tasking. Our training reflects a brain-friendly learning approach that is multi-sensory, facilitative, honours our multicultural students’ unique qualities, and ‘keeps it real’, ensuring they are competent and confident when they leave. We do not ‘hose’ them with information, but instead allow them to explore through a mix of visual, auditory and other kinaesthetic learning, while emphasising the context in which they are operating. Integrating our safety and service training ensures that our cabin crew have safety at the heart of everything they do, whilst delivering an exceptional customer experience.

(c) You are restricted to a 1.5nm arc area to the west of the aerodrome due to terrain restrictions (d) You are restricted to a 1.5nm arc circling area joined by tangents for the whole circling area due to terrain restrictions. Flight Safety Australia Issue 85 March-April 2012 3. Refer to the Georgetown (YGTN) Queensland NDB (a) 670ft and descent on base What is the size of the circling area for this approach plate? (b) 720ft and descent on base (a) 3nm radius centred on the aerodrome reference point (A.R.P) (d) 570ft and descent late base to final. (b) 3nm arcs from the thresholds of the runway 06/24 joined by tangents (c) 1.68nm arcs (category A) and 2.66NM arcs (category B) from the thresholds of runway 06/24 joined by tangents (d) 1.68nm radius (category A) and 2.66NM radius (category B) centred on the A.R.P. 4. You are on final approach of the Griffith (YGTH) NDB-A approach You are at the MDA for your category B aircraft with 0.5nm to run to the beacon when you break visual. Where do you expect to see the aerodrome as you establish cloud break? (a) Directly in front of the aircraft (b) In front and to the right of the aircraft’s nose (c) Off the right wingtip (d) Off and behind the left wingtip. 5. Which of the following is a true statement concerning the minimum obstacle clearance during a circling manoeuvre on a ‘new-style’ chart. (a) 300ft for category A and 400ft for category B (b) 300ft for categories A and B (c) 400ft for categories A and B (d) 400ft for category A and 300ft for category B. 6. Which of the following is a true statement concerning the minimum obstacle clearance during a circling manoeuvre on an ‘old-style’ chart. (a) 300ft for category A and 400ft for category B (b) 300ft for categories A and B (c) 400ft for categories A and B (d) 400ft for category A and 300ft for category B. 7. You have established cloud break at the MDA on the Moorabbin (YMMB) NDB-A approach. It is night and you have received the AWIS (outside tower hours). The AWIS wind is 180/25kt. Since the cloud break was close to the beacon, you elect to overfly and position for a left circuit to runway 17. What is the cloud ceiling at your MDA and when would you commence descent from this height for the approach to land? (c) 570ft and descent turning base 8. You are inbound on final approach of the Albury (YMAY) NDB-A approach at night. You are at the MDA for your category B aircraft with 1nm to run to the beacon when you establish cloud break with the runway lights in sight. The wind favours a landing on runway 07. Due to lower scattered cloud north of the aerodrome you elect to overfly for a right circuit to runway 07. When can you descend from the MDA to set up the approach to land? (a) Continual visual descent during the overfly and on downwind to achieve ‘normal profile’ turning base at circuit height (b) Continual visual descent ensuring the minimum obstacle clearance of 300ft until turning final (c) Only when established on the base leg for runway 07 (d) Only when established on final approach for runway 07. 9. Refer to the Nhill (YNHL) Victoria NDB-A approach. You are established clear of cloud and with the threshold of runway 27 in sight at the MDA for your category B aircraft. On the left downwind leg for runway 27 you re-enter cloud. What actions must you now take? (a) Descend to re-establish visual reference, being aware of the obstacle clearance requirement of 300ft until turning final (b) Execute a missed approach, turning left to the NDB and then tracking 050 while climbing to 2400ft (c) Execute a missed approach, manoeuvring to immediately intercept a track outbound of 050 while climbing to 2400ft (d) Maintain the M.D.A. whilst turning left to the NDB then execute the missed approach, tracking 050 and climbing to 2400ft. 10.If the weather conditions are such that you establish visual reference at the MDA and with the specified circling visibility, there is no minimum number of legs of a circuit to fly, or any requirement to fly the specified circuit direction. True or false? (a)True (b)False. 69 70 CALENDAR March-July 2012 Upcoming events NORTHERN TERRITORY May 12 Ageing Aircraft Seminar – Darwin www.casa.gov.au/ageingaircraft QUEENSLAND 24-26 JULY Aircraft Airworthiness and Sustainment Conference, Brisbane QLD www.ageingaircraft.com.au/aasc.html ACT/NEW SOUTH WALES March 8 AvSafety Seminar – Moree www.casa.gov.au/avsafety March 13 AvSafety Seminar – Nowra www.casa.gov.au/avsafety March 15 AvSafety Seminar – Ballina www.casa.gov.au/avsafety March 21 AvSafety Seminar – Coffs Harbour www.casa.gov.au/avsafety April 6-7 Natfly 2012: The sky is no limit – Temora http://www.natfly.com.au/ April 11 AvSafety Seminar – Moruya www.casa.gov.au/avsafety April 12 AvSafety Seminar – Merimbula www.casa.gov.au/avsafety April 15 Wings, wheels, wine and wool’ – Mudgee http://mudgeeaeroclub.hwy.com.au/ April 28 Ageing Aircraft Seminar – Sydney www.casa.gov.au/ageingaircraft May 6 Wings over Illawarra family air show Albion Park www.woi.org.au March 1 AvSafety Seminar – Latrobe Valley www.casa.gov.au/avsafety March 14 AvSafety Seminar – Point Cook www.casa.gov.au/avsafety March 7 AvSafety Seminar – Goondiwindi www.casa.gov.au/avsafety March 21 AvSafety Seminar – Ballarat www.casa.gov.au/avsafety March 14 AvSafety Seminar – Coolangatta www.casa.gov.au/avsafety April 18 AvSafety Seminar – Warrnambool www.casa.gov.au/avsafety March 28-29 ATO Professional Development Program Cairns www.casa.gov.au April 18-19 Certification Flight Testing Seminar Melbourne www.casa.gov.au April 14 AvSafety Seminar – Heckfield www.casa.gov.au/avsafety June 2 Ageing Aircraft Seminar – Brisbane www.casa.gov.au/ageingaircraft July 24-26 Aircraft Airworthiness and Sustainment Conference – Brisbane www.ageingaircraft.com.au/aasc.html SOUTH AUSTRALIA March 21 ATO Professional Development Program Adelaide www.casa.gov.au March 25 Parafield Airshow – Parafield www.parafieldairshow.com.au June 16 Ageing Aircraft Seminar – Adelaide www.casa.gov.au/ageingaircraft April 18-19 ATO Professional Development Program Bankstown www.casa.gov.au April 18 AvSafety Seminar – Broken Hill www.casa.gov.au/avsafety VICTORIA To have your event listed here, email the details to [email protected] Copy is subject to editing.

(a) There is no CSD The wire to the cockpit switches It is more effective to inertially separate larger water droplets YBDG NDB approach plate. Note the ‘no circling’ west of 17/35 centreline. This also precludes the use of runway 05. YLIS-A approach plate. Answer B is ordinarily correct for category B aircraft, but at Lismore there is a further 1.5nm restriction to the west. Remember also that these circling area distances are the maximum surveyed area for the category of aircraft. On poor-visibility days or nights you will be ‘tucked in’ closer to the field to maintain the flight visibility required, while (and this is vitally important!) keeping the approach end of the runway in sight. DAP EAST.DAP 1-3 i.e. ‘old’ chart. Note that answer B is correct if the runway is longer than 1800m. YGTH-A approach plate. This is vital to be aware of, pre-flight, so that you can smoothly transition from instruments to the visual manoeuvre at the cloud break. DAP East or West DAP 1-3 DAP East or West DAP 1-3 YMMB-A Approach plate. AIP-ENR 1.5-33 para 5.3.2 AIP-ENR 1.5-3 para 1.7.6 This descent from a position on the ‘normal profile’ is vital to achieve obstacle clearance and is strongly recommended, both day and night, even though daytime regulations might allow a clearance of 300ft (new) or 400ft (old) until on final. The question is – above what? You might not have this information available, so maintaining the MDA to that position for a descent from normal circuit height will ensure clearance. YMAY NDB-A approach plate AIP-ENR 1.5-8 Figure 1 YNHL NDB-A approach plate. AIP-ENR 1.5-9 para 1.10.1 e para 1.10.3 A good point to note here is that the NHL NDB is a significant distance (1.3nm) north of the aerodrome. AIP-ENR 1.5-4 para 1.7.6 note 1 Ideally, left hand is better while conducting the visual circling manoeuvre, since this will give the (single) pilot in the left seat the best view. Once cloud break occurs, it is vital to place the heading bug on the runway heading to help maintain orientation, particularly in conditions of low visibility and at night. 71 NEXT ISSUE / PRODUCT REVIEW Essential aviation reading COMING NEXT ISSUE Product review MAY-JUNE 2012 ONTRACK Helicopter safety The Heathrow Trident crash Sharing the skies ... trikes ... and more close calls Sunshine Coast Airport is the latest addition to OnTrack, CASA’s interactive guide to operating in and around Australia’s controlled airspace.
