The Aeronautical Information Exchange Model (AIXM) and the related Aeronautical
Information Conceptual Model (AICM) contain hundreds of entities, data types, and
relationships used to represent aeronautical data. AICM and AIXM were originally
developed by EUROCONTROL to aid in standardizing data exchange and aeronautical
products within the European States. The models are primarily based on ICAO
requirements for international aeronautical data exchange (Annex 15 to the ICAO
Convention) and on industry standards such as ARINC 424. AICM and AIXM's adoption
within the United States government means that aeronautical data providers
and consumers are almost certain to encounter AIXM in the near future. This paper
provides an overview of the AICM and AIXM structure. AICM and AIXM may be
divided into six concepts—Airspace, Services, Fixes, Routes, Aerodromes and
Procedures. We highlight the major entities and relationships within these data concept
areas and discuss AIXM's geographical model for representing the locations and extents
of the aeronautical data entities.
