AIXM Change Control Board


The objective of the AIXM Change Control Board (CCB) is to maintain and to evolve the AIXM Specification as necessary for enabling States to comply with the ICAO global and regional requirements for the provision of aeronautical information, in the context of the evolution towards digital AIM and System Wide Information Management (SWIM).



The members of the AIXM CCB represent a wide range of stakeholder organisations from many parts of the World. They act under the provisions of the Change Management Charter (“Charter”), which also defines the change management processes.

  AIXM CCB Charter

The AIXM CCB is open for participation to any AIXM stakeholder organisation, condition that the proposed member has a very good knowledge of the AIXM model and a business interest in the further evolution of the model. Currently, the AIXM CCB comprises representatives from around 55 organisations, with the following profiles:

Future AIXM versions

The maintenance and evolution objective is achieved through the release of new AIXM versions. These include both the core specification components (UML model, XML Schema, Temporality Concept) and also the associated documents (GML Profile, Feature Identification and Reference, etc.). The following versioning policy is applied.

AIXM 5.2

The next regular AIXM update is scheduled for publication in January 2023, with the following objectives:

  • to enable the provision of ICAO data sets (except for terrain data), as specified in the new Annex 15 and PANS-AIM. This includes the development of guidance material for the provision of the data sets and of the associated metadata in a globally interoperable manner;
  • to enable an initial global implementation of Digital NOTAM, including support for the new Runway Condition Report
  • to enable the provision of data that supports the deployment of “performance based” ICAO concepts, such as PBN, etc.
  • to enable the provision of GNSS data necessary for air navigation
  • to enable data provision for emerging concepts such as free routes, large-scale use of RPAS, etc.
  • to ensure the interoperability of aeronautical data (AIXM) with flight data (FIXM) domain and with the MET data (iWXXM) domain;
  • to correct issues and limitations detected in the previous versions.

Currently, the AIXM CCB is working on finalising the new AIXM 5.2 version. An partial candidate release is available. Updates about the work in progress are provided through a dedicated page (  version 5.2 - work in progress).

AIXM 5.3

After version 5.2, it is estimated that a future regular AIXM update might be necessary around 2025 (at the earliest). Possible objectives for that version include:

  • alignment with the ICAO SWIM requirements as developed by the ICAO Information Management Panel;
  • enable the provision of new aeronautical data elements specified by ICAO, in particular in support of FF-ICE;
  • enable the provision of aeronautical data in support to future ATM concepts, such as time based operations (TBO);
  • ensure the interoperability of aeronautical data (AIXM) with the evolving needs of the flight data (FIXM) and MET data (iWXXM);
  • correct issues and limitations detected in the previous versions;
  • provide Guidance material for the implementation of AIS data services compliant with the SWIM concepts.
