I have seen in many ICAO regional offices workshops talking about AIXM interoperability tests, not much background is given on what they want to accomplish. The secretariat paper referenced at the end of this post makes certain claims in paragraph 2.2 and 2.3 which in essence say there is no compatibility but there it doesn’t say what tests were made and under what scenarios. It also talks about compatibility checks between versions that AIM staff will most likely not have the knowledge at technical level to perform.
So what is the goal of AIXM tests at this point? If you receive information from another country at this moment what is your use case? Does it matter if you receive AIXM 4.5, AIXM 5.0, AIXM 5.1, AIXM5.1.1? I am sure many countries have still no use case for receiving external data as they can’t still cope with their internal issues
In the Latin American case many countries don’t even have a fully functional eAIP but we are talking about making exchange of AIXM data? In other countries you see eAIP made several years ago with no updates so making an educated guess they bought a system including data migration from vendor and now maintenance and support ended and they never learned how to update it
Unless you are building a datawarehouse I see little use cases at AIM level, at most you will need a few boundary points, routes and airspaces.
So when AIM regional offices talk about AIXM interoperability tests what is the expected result? Most likely you will not upload in you AIXM system data from other ANSP (external), you will not receive AIXM data throught AMHS (not talking about digital NOTAMs yet) so what will you test?
Sometimes I don’t know what are the intentions of regional offices but for sure if I export AIXM data what will you do with it?
Let’s make some discussion around this, I want to see your comments on this topic and maybe together we can have a clearer idea, but honestly at this point I would be more engaged on having a functional eAIP and producing datasets than doing these types of things as many countries are still not even in the implementation phase to even bother.
