AIXM version 5.2 - work in progress

AIXM 5.2 is scheduled for publication in Q1 2022, with a Release Candidate expected in December 2021. This page contains information about the AIXM Change Control Board (CCB) work in progress and will be updated regularly with information about issues that are being discussed, change proposals, publication calendar, etc.

Current status

In July 2021, a total of 218 open “issues” were recorded in the JIRA tool used by the CCB.

From these, 128 issues have been identified as candidates for AIXM change proposals in AIXM 5.2. The following chart shows a distribution of these issues per their status:

The diagram above indicates that 65 issues were still under investigation, while 25 issues were parked away and might be considered in a further version.

These issues range from small/localized bugs and improvements (such as corrections to definitions of terms), to new capabilities such as support for free route airspace data and an extensive model for seaplane landing areas.

None of these issues was identified as a blocking point for the use of AIXM 5.1 in the coding of the digital data sets prescribed by the revised ICAO Annex 15 (AIP data sets, Instrument Flight Procedures Data sets, Obstacle data sets, Airport mapping data sets). However, the AIXM 5.2 version will certainly facilitate the provision of the new data sets, in particular for the Instrument Flight Procedures Data Sets.

Change proposals

The complete descriptions of all already approved change proposals is made available on the AIXM/Confluence web site.

This will be followed by two or three more batches of AIXM change proposals, until the publication of the first AIXM 5.2 Release Candidate in December 2021.

The most significant set of change proposals for AIXM 5.2 concerns the Procedures model, including a complete new model for GNSS (primary, SBAS, GBAS). These changes are part of "Lot 4", which is approaching finalisation and will be submitted for formal approval at the end of September 2021.
