Aeronautical Information Exchange Model

The objective of the Aeronautical Information Exchange Model (AIXM) is to enable the provision in digital format of the aeronautical information that is in the scope of Aeronautical Information Services (AIS). The AIS information/data flows that are increasingly complex and made up of interconnected systems. They involve many actors including multiple suppliers and consumers. There is also a growing need in the global Air Traffic Management (ATM) system for high data quality and for cost efficiency.

In order to meet the requirements of this increasingly automated environment, AIS is moving from the provision of paper products and messages to the collection and provision of digital data. AIXM supports this transition by enabling the collection, verification, dissemination and transformation of digital aeronautical data throughout the data chain, in particular in the segment that connects AIS with the next intended user.

The following main information areas are in the scope of AIXM:

  • Aerodrome/Heliport including movement areas, services, facilities, etc.
  • Airspace structures
  • Organisations and units, including services
  • Points and Navaids
  • Procedures
  • Routes
  • Flying restrictions

AIXM takes advantages of established information engineering standards and supports current and future aeronautical information system requirements.

This web site provides complete documentation for the AIXM versions in use, including information about coding guidelines, support for implementation and links towards other relevant resources.
