A Need for AIXM
• Current AIS information exchange was based on procedures
and needs for the teletype era.
– Error prone (both human and computer) as well as inefficiencies
• The goal for AIXM 5 is to provide an extensible, modular
aeronautical information exchange standard that can be used
to satisfy information exchange requirements for current and
future aeronautical information applications
AIM System
- manage data
- publish traditional and new products
- accurate and fast exchange
Classical AIS
- publish documents
AIP
SUP,
NOTAM,
AIC
Document content and format is described by:
Data managed in the system is described by models:
- ICAO Annex 15, Appendix 1 – AIP Content
- ARINC 424
- ICAO Annex 15, Appendix 6 – NOTAM format
- Aeronautical Information Exchange Model (AIXM)
- ICAO Annex 4, Aeronautical Charts
- Electronic AIP (eAIP) Specification
- FAA forms
- Airport Mapping Database (AMDB)
- Terrain and Obstacle Database
- New products…

Global AIM community
• Global recognition that AIS is the key to
global interoperability
• Global recognition that aeronautical
information is crucial to realize a safe and
efficient air traffic system
• Adopt the Aeronautical Information
Exchange Model
– Examples are: FAA, EUROCONTROL,
NAVCANADA, etc.

History of AIXM
AIXM is a standard for aeronautical information dissemination that has been
based on:
•
ICAO Annex 15 “data to support international air navigation”
•
Industry standards like ARINC 424 (for encoding terminal procedures)
•
Other standards and best practices
•
Real world aeronautical information publications
It also took into consideration aspects that are not subject to formal
requirements:
• Examples: route usage restrictions, declared distances from
runway/taxiway intersections, airspace aggregations, fuel types, etc.
• AICM (the conceptual part of AIXM) - Started by Eurocontrol in 1996
• AIXM – started in 1997
• First attempt “SQL based”
• Move to XML in 1999
• EAD operational since 2003 – All European States are expected to have
joined the EAD by end 2008

AIXM5 concepts
•
AIXM5 design decisions are based on the
adoption of a number of international
standards:
– Use GML (Geography Markup Language) for
encoding geographical information – positions,
areas, routes, etc.
Technical Design Decisions
ISO19100
series
UML
• As opposed to the custom geometry encodings used
in the current AIXM 4.5
– Use the ISO19100 series of geospatial information
standards as data modeling framework
GML 3.2
• This would maximize the chances of cross-domain
interoperability
– Use UML (Unified Modeling Language) for
developing AIXM 5 Conceptual Model
•
Closely linked to the ISO 19100 modelling
framework, the requirement for exhaustive
metadata incorporation into the model has
been identified

Case studies
• A number of case studies were presented in Lima
– EUROCONTROL presented xNOTAMS
• In 2007, the project was in the “initiation” phase, which was
going to be followed by an evaluation of the feasibility and a
planning phase, and start implementation by 2011-2012.
– FAA D-NOTAMS
• The initial POC for D-NOTAMS was presented in the conference.
An initial formulation of the AIXM protocol was discussed within
the context
– AIXM Viewer
• An AIXM viewer developed by the University of Maryland was
demoed to show how to interpret the model in a geospacial
environment
