FMB: Spawning in hangars

[Flashman]

There is a section in the FMB called 'airfield' with 'airfield points'

I have been experimenting and it seems you can created your won airfield but i don't fully understand how the airfield points work. Anyone know how these are used?

Im trying to use these in map airfields so you don't spawn in the hangars and am having some success, though not complete.

If anyone can explain how these points can be used it might go some way to fixing some of the airfields for MP spawning.
