5 System Safety Considerations
5.1 Functional Hazard Analysis
The following Functional Hazard Assessment is based on the guidelines presented in AC 23.13091D, figure 2 and Appendix A. Ultra believes that within these limitations there is no difference in the
“Classification of Failure Conditions” between Class I and Class IV airplanes. The allocation of
failure probabilities in the Failure Modes and Effects Analysis will differ between the classes but,
the system level probabilities will not differ among classes.

7 Installation Instructions
7.1 Display Unit (DU) Installation
7.1.1 Choose the Proper Installation Location
The DU is best located within the natural scan and easy reach of the pilot. The recommended
mounting location is defined as an imaginary box defined with respect to the Primary Flight
Instrument “T” and the control wheel axle.
The recommended optimal mounting location is within a box (see Figure 2: Suggested
AuRACLE Mounting Area) as defined below:
HORIZONTAL ORIENTATION:
The centerline of the AuRACLE LCD display may be mounted from the left side of the Instrument
panel to a maximum of 21” to the right of the vertical centerline (Control Wheel center of rotation).
The idea is mount the centerline of the AuRACLE LCD display no more than 21” to the right of the
Pilot’s centerline; so that the Pilot may easily read and interact with the AuRACLE.
VERTICAL ORIENTATION:
The AuRACLE may be mounted within +/- 7” from the horizontal centerline of the Primary Flight
Instrument “T”. The installer should insure that the AuRACLE display is not obstructed by either
the glare shield or the control wheel.
Note: Any installation that requires that the AuRACLE be mounted outside of the Box will require
FAA involvement for installation approval.

1. Remove the Instruments in the chosen installation area that are replaced by the AuRACLE
(For the example shown above: Manifold Pressure, Tachometer, Fuel Flow, and EGT. For a
list of possible replacements see section 4.2).This will provide most, if not all, of the space
required to install the AuRACLE. Remove or relocate other instruments that will interfere
with the following steps. This location is for reference only. The installing A&P and IA
should decide that where the installation is to occur does not conflict with the viewing angle
suggestions listed above and is consistent with all applicable Advisory Circulars.
Note: Any appliances that are installed under the original Type Certificate (TC) that requires
relocation should be relocated in accordance with the guidance provided in AC.23.1311-1B,
Section 15.4 (presented below). Special care should be exercised to insure that proper pilot
visibility of displays and pilot access to controls in not interfered with, with respect to relocated
instruments and non-relocated instruments.
Note: Any appliances that are installed under a Supplemental Type Certificate (STC) that requires
relocation should be relocated in accordance with the original STC installation instructions or in
accordance with the guidance provided in AC.23.1311-1B, Section 15.4 (presented below).
Special care should be exercised to insure that proper pilot visibility of displays and pilot access to
controls in not interfered with, with respect to relocated instruments and non-relocated instruments.
Excerpt from AC23.1311-1B
15.4 Recommended Location for Displaying Information
Table 1 contains the recommended location for displaying information intended for new panel
layout with integrated electronic displays; however, these guidelines should be followed for other
installations as practicable. Deviations beyond these limits may be approved for individual flight
instruments depending on the combination of factors listed in section 15.1. These deviations need
a display installation evaluation. It may not be practicable for retrofit installations with new
electronic displays, such as with ATC, STC, and field approvals, to comply with the values in the
table. This is due to limitations in the systems and incompatible technologies between the aircraft
and the system being added. In such cases, for any given item, the angular deviations should not
increase from what was originally found to be acceptable, and the display characteristics should be
at least as good as the original display. For retrofit installations, it may be acceptable for
installations to fall outside the recommended data in Table 1. These deviations may need an
evaluation by the certification authority. Factors to consider during this evaluation include the
distinguish ability, attention-getting quality, readability, etc. The field-of-view angles should be
applied for installation approvals where a design eye reference point exists. For installation
approvals where no design eye reference point is defined, the linear panel distances from center in
Table 1 should be used.

NOTE 1. The FOV angles and Approximate Distance from Center Reference Line, based on a viewing
distance of 30 inches from the panel, are defined as acceptable angles and distance to each data source from
the center of basic T, or pilot view centerline. Distances are measured center-to-center of the display in
question, measured horizontally. Vertical placement in the panel can be from just below the basic T to the
glare shield.
NOTE 2. Display PFI as close to the center of reference as possible.
NOTE 3. The navigation source annunciation should be on or near the affected display and should appear on
the same side of the basic T as the affected display. The guidelines for the proximity to the affected display
depend on the size, color, and distinguishing characteristics of the source annunciation.
NOTE 4. Warnings and cautions can be presented within 35 degrees if they are associated with a unique aural
tone or a master warning/caution light that is within 15 degrees. The warnings and cautions should be in a
consistent location, such as on an annunciator panel. If an aural tone is used, it should be readily
distinguishable from all other cockpit sounds and provide unambiguous information to direct the pilot’s
attention to a visual indication of the condition. Consider the number of aural alerts.
NOTE 5. Install the standby instruments as close as practicable to the PFI.
7.1.3 Cut-out DU Installation Holes
If the panel has too many holes for a clean installation, it is recommended that an 0.100” Aluminum
overlay panel be constructed and installed (4 to 6 6-32 screws) over the original instrument panel
and the AuRACLE DU be installed into this overlay panel. The photo below shows a typical
overlay panel type installation.

1. Once the general site for the AuRACLE DU is determined, a small hole is drilled in the
instrument panel in the approximate center of the large hole in the template. A screw and
fender washer is then used to hold the template, through hole “D”, in place against the
instrument panel.
2. It is now possible to fine tune the position of the template. Once the final position is
determined tighten the mounting screw to firmly secure the installation template.
3. Using the 140-000158-001 template holes as a guide, drill all ten (10) holes “B” , “C”, and “E”
using the respective specified sized drill.
4. Connect the 4 - 0.250 holes “D” with straight-lines and cut-out the mounting hole accordingly.

Figure 20: Typical EIU & Network Cable Installation (Cessna 414A)
7.3.2 Install Network Cables
1. Routing the network cables and terminating them is the most difficult part of the
installation. It will depend on the location of the Fuel Quantity Unit (FQU) and the location of
the existing engine sensor wire runs out to each nacelle. It will be easiest to run the network
cables in the same place that the old sensor wires were run. Each network cable will end up
with two (2) ferrite beads installed, one at the DU and the other at the EIU. The ferrites at
the EIU’s will be installed on-site along with the EIU network cable connector (see attached
installation instructions).
2. Start by feeding the cables from the DU location and out to the right engine and to the
FQU. The connector that you will install at the FQU will be a standard Cannon type without a

ferrite or shrink wrap. The connector at the EIU will have a ferrite bead with shrink wrap and
a waterproof connector with shrink wrap.
7.3.3 Terminate Network Cables
- Position ferrite core item 5 on the cable assy. to dimension shown on figure 11 and the shrink
tubing, item 6 over to keep the core in place.
- Separate the clamp body, the two pressure rings, the sealing grommet, the clamp and the O-ring
from the backshells.
- Slide the backshell components over the cable. The farthest part from the connector is the
clamp, followed by a pressure ring, then the grommet, then the other pressure ring, then the clamp
body and then the O-ring as shown on figure 8.
Assembly Note: The grommet is a layered design. For our application remove and discard the
smallest layer of the grommet. If the grommet resists sliding over the cable, lubricate with isopropyl
alcohol.

Figure 24: EIU Sensor Interface Cable J1-2, Connector Pin Definition
7.4.2 EIU Sensor Interface Cable J1-1
Note: The AuRACLE EIU Sensor Interface Cable J1-1, 4-Cylinder cable is pre-manufactured for
you with labeled “flying leads” for each of the respective connections. Modifications for length can
be made at the installer’s discretion. DO NOT attempt to remove or add additional wire
connections to the connector. This will compromise the integrity of the connector and will void your
warranty preventing legal installation in certificated aircraft as the integrity of the connector seal
can no longer be guaranteed.
Note: This connector is keyed; insure you are inserting it in the proper position and in the proper
orientation. Failure to perform this insertion properly will result in damage to the EIU.

7.4.3 Sensor Wiring General Recommendations
ALL sensor wiring should be routed away from high temperature areas
ALL sensor wiring should NOT be routed with ignition, alternator, or other high-current
carrying connections.
When the installation is complete, all wires should be secured and carefully checked for
interference, chaffing, etc. Use best practice wiring techniques.
Note: If any sensors are not installed. The associated wire may be cut short. In any case,
insulate individual conductors so that they do not short to each other or anything else.
7.4.4 Thermocouple Wiring General Recommendations
When cutting the pair of leads to the proper length to connect to the sensors, leave enough
slack in the wiring so that sensors may be interchanged to an adjacent cylinder if necessary
for trouble-shooting and servicing.
Thermocouple wire length is not critical and should be trimmed to any length as required for a
clean installation.
The Temperature sensor must be wired with the correct polarity. The temperature sensor
connects to its temperature indicator with thermocouple wire supplied. Strip the wires as
shown below—observing color-coding.
Terminate each wire with a crimp-on ring terminal. The ring terminals may be crimped with a
“service-type” tool, however AMP part number 48518 crimp tool is recommended. Verify the
quality of each crimp with a sharp tug on the wire. The terminal should be impossible to pull
off when crimped correctly. Place a ¼ x 4-inch sleeve over each pair of wires in the wiring.
Connect the wire ring lug to the sensor ring lug using the supplied number 4 screws and nuts,
placing the star washer between the ring lugs, not against the nut.
Slide the protective sleeve over the joint and secure with tie-wraps.

Note: On both Type-J and Type-K thermocouples one wire of the pair is magnetic and the other is
not. One can always determine how to connect wires with a small magnet. Always connect
magnetic wire to magnetic wire and connect non-magnetic wire to non-magnetic wire.
WARNING: Do not extend thermocouple wire with copper wire.

7.4.19 Install Fuel Flow Sensor
The inlet and outlet ports in the fuel flow transducer have ¼” NPT threads. Use only ¼” NPT hose
or pipe fittings to match. When assembling fittings into the inlet and outlet ports DO NOT EXCEED
a torque of 180 inch lbs, or screw the fittings in more than 2 full turns past hand tight WHICHEVER
HAPPENS FIRST.
If possible, secure the transducer using two 0.25-inch bolt holes through the body of the transducer
to the structure of the aircraft. This will provide the most secure installation. Please be aware of
any heat sources the transducer might be subjected to during operation.
If the installation prevents you from bolting the transducer as mentioned above, you may “suspend”
the transducer within an existing grouping of fuel lines as long as they are supported with Adel
clamps or something similar.
The Floscan flowmeter is designed to allow fuel to continue to flow with minimal pressure drop if
the rotor becomes seized. If the rotor becomes seized, the displayed Fuel Flow on the AuRACLE
will drop off dramatically with little or no recognizable decrease in engine power. Additionally, you
may witness a drop in the monitored fuel pressure if installed, provided the fuel flow sensor is
located on the METERED side rather than the UN-METERED side.
Once the Fuel Flow transducer installation is completed, an engine run-up should be performed
verifying the minimum Fuel Flow based on the aircraft POH.
Post-installation Calibration is necessary only in the programming of the AuRACLE with respect to
the transducer “K-Factor. This is documented on the tag that is attached to the sensor and should
be recorded in this manual for use later. To determine the “K-Factor”, refer to the tag attached to
the sensor (KEEP THIS TAG!). Note the number 16-2959 in Fig 38 below. The “K-Factor” for this
particular sensor is 29590 (note the added “0”) and you would enter this in the “K” field in the
“SETUP MENU”.

A screen or filter should be installed upstream of the flow sensor to screen out debris which could
affect rotor movement or settle in the V-bearings.
Mount the fuel flow sensor in a position so the three wire leads are pointed straight up. Use only
smooth radius curves in the fuel line and place the sensor with 5” of straight line before and after.
The sensor should be mounted according to the fuel metering device manufacturer’s
recommendations.
Based on the aircraft fuel system, one of the following sensor locations should be chosen:
Previous installations have yielded exceptional results when the following conditions have been
met:
1. The sensor is mounted in a stationary location in line between the electric boost pump and

8 Aircraft Configuration Verification
Once the Operational Parameter file has been downloaded to the AuRACLE, it is the responsibility
of the installation technician to verify the AuRACLE is configured properly against the appropriate
Instrument Marking Report.
The Pilot’s Guide will guide you through the SETUP page and sub-menus. You can use these
procedures to make any required changes as well as to verify settings.
The scales, caution limits and warning limits must be verified for every instrument. Failure to do so
could present improper readings.
WARNING: The scales, caution limits and warning limits must be verified for every instrument.
Failure to do so could potentially damage the engine or put the pilot and occupants in a potentially
dangerous situation. Until the configuration is confirmed and the Box and Signature line below
checked, the installation cannot be signed off as Airworthy. Please contact Ultra Electronics Flightline Systems at 800-405-8608 with any questions.
