Key Concepts

Aeronautical Information Exchange

The Aeronautical Information Exchange Model (AIXM) is designed to enable the management and distribution of Aeronautical Information Services (AIS) data in digital format.


AIXM 5 takes advantages of established information engineering standards and supports current and future aeronautical information system requirements. The major tenets are:
An exhaustive temporality model, including support for the temporary information contained in NOTAM
Alignment with ISO standards for geospatial information, including the use of the Geography Markup Language (GML)
Support for the latest ICAO and user requirements for aeronautical data including obstacles, terminal procedures and airport mapping databases
Modularity and extensibility

  Maintenance and Evolution
  AIXM 5 was initialy developed by the US Federal Aviation Administration (FAA) and the European Organisation for the Safety of Air Navigation (EUROCONTROL) with support from the international community.  
  The further evolution of the AIXM shall be managed in the interest of the largest number of AIXM stakeholders. A Change Control Board (“CCB”) with international participation is therefore established.
