how to read apt.dat files from lua, or interpret airport layout in general

[cw777]

I am aware that apt.dat files create the understood layouts of airports - but can only find this file for a small group of airports by aerosoft. Where can I access layout data (taxi ways, etc) for any given airport? The data must be somewhere as on 'select airport' page, there seems to be the correct layout of pretty much all airports. I want to be able to iterate through this taxi data of any airport in a lua script..

 

Cheers for any guidence.

There's a global apt.dat in the resources folder.
