Sorry, I was getting mixed up: parking and ground-net data comes from ground-network.xml, used by AI for taxi-paths. ‘Visible’ taxiways / aprons comes from apt.dat as you point out, and only exists from some subset of airports. We have a long-standing issue to get the taxiway data out of apt.dat (since it bloats it) and into the ground-net files, since that would also make editing easier.

But, the flip side then is airport BTG generation needs the ground-net files, which currently it does not.

This is all my recollection anyway - does that with the observed behaviour and other people’s understanding? Corrections are welcome, as are bug-fixes :)

Kind regards,
