AIXM

Aeronautical Information Exchange Model

Public access Access conditions

Initially developed by EUROCONTROL for the European AIS Database (EAD) project, the Aeronautical Information Exchange Model (AIXM) has evolved into a global specification for the encoding and the distribution in digital format of the aeronautical information.

The AIXM specification is now managed by an international Change Control Board (CCB) established through the joint effort of EUROCONTROL and the United Stated Federal Aviation Administration (FAA). The main objective of the AIXM CCB is to support the provision of digital data sets by national Aeronautical Information Services (AIS) in accordance with the Annex 15 (16th edition) to the ICAO Convention.

Functionality

AIXM provides a logical data model (UML class diagrams) and an XML schema that enable the coding of the aeronautical information that needs to be collected, managed and provided by the Aeronautical Information Services (AIS). This is complemented with coding specifications and verification rules/services for particular AIS products, such as the AIP data set, Instrument Flight Procedures data sets, Obstacle data sets, Airport Mapping data sets.

AIXM supports the coding of both the 'static data', equivalent to Aeronautical Information Publication updates, and 'dynamic data', equivalent to NOTAM.

The focus of the AIXM specification is the upstream data chain, from data originators down to the publication by AIS of digital data sets. There exist many commercial and free applications for AIS that use AIXM as data coding and data exchange specification.
