Framing the NOTAM problem
NOTAM Users experience an
overload of information that is
not easily managed to provide
them with the critical real time
information on the NAS
relevant to their needs
NOTAM Originators
experience significant delays
between the time they observe
and report the hazard
condition and when the
NOTAM is issued to the
aviation community

Analog (text) vs Digital NOTAM
• Analog NOTAM
– Text string distributed by telecommunication
• Limited validation
• Limited sorting/searching capability
ACY RWY 13/31 CLSD
• Digital NOTAM
– Data set made available through digital services
• Validate against baseline data
• Translate/Graphically Display
NOTAM Information
• Improve data quality

Text Based Routing
• From DCA
• 600 Maryland Ave SW, Washington DC
Head north on S.Smith Blvd. Take the ramp onto George Washington
Memorial Parkway. Take the I-395 N exit toward Washington. Merge
onto US-1. Continue onto I-395N. Take the 12th St exit toward L’Enfant
Promenade. Slight right toward D. St. SW. Slight Right onto D St. SW.
Turn left at the 2nd cross stre onto 7th St. SW. Take the 2nd right onto
Maryland Ave SW. Destination will be right

International Collaboration
• Two areas of International Collaboration
– Aeronautical Information Exchange Model (AIXM)
– Defining Event Scenarios for Digital NOTAMs
• Digital NOTAM Focus Groups – collaboration between the FAA,
EUROCONTROL, ECAC Member States, airlines, and industry
• Detailed description of the Event Scenarios and their encoding as a Digital
NOTAM (using AIXM version 5.1)
http://www.aixm.aero/public/subsite_homepage/homepage.html
• Benefits
– Establish a set of international standards and specifications for
exchanging digital information
– Efficient exchange of NOTAM information between operational
systems
• Goal
– Enable the machines that assist the specialist to provide a common
and accurate view of the aeronautical 4D environment

What is a Digital NOTAM?
AIXM (XML) Message
• Digital NOTAM Definition
– A dataset that contains NOTAM
information in a structured format
– Fully interpreted by an automated
system without human intervention
• Characteristics of Digital NOTAMs
–
–
–
–
–
–
Geo-referenced
Temporal
Linked to static data
Transformable
Query enabled
Electronically distributable

Aeronautical Information Exchange Model
• AIXM is designed to enable
the management and
distribution of Aeronautical
Information Services (AIS)
data through the use of a
common exchange model
• Developed by the FAA and
EUROCONTROL with
support from the
International Community

Benefits to using AIXM
• Achieve neutrality against applications and their local views
of the data
– Display customized for end user
• Improved safety
– Reduce data inconsistencies, computer readable data means fewer
errors for pilots and other users
– Automated processing of information
– Ensure the quality of the Aeronautical Information required by modern
air navigation and ATC systems
• Represents both static and dynamic data
• International Digital Harmonization
– Establish a set of international standards and specifications for
exchanging digital information
