Future AIXM version 5.2

AIXM 5.2 is scheduled for publication in Q1 2020, with a Release Candidate expected in February 2020. 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

At the end of October 2019, a total of 188 open “issues” were recorded in the JIRA tool used by the CCB and around 95% are considered for resolution the AIXM 5.2 update process. The following chart shows a distribution of these issues per their status:

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.

Another objective for AIXM 5.2 is to improve the interoperability of aeronautical data (AIXM) with the flight data (FIXM) domain and with the MET data (iWXXM) domain. This includes the introduction of the "deprecation" mechanism for features/properties that are no longer used or are replaced by a new concept, where a common approach was agreed in a cross-XM coordination effort.
