By default, FlightGear reads parking positions from 
AI/Airports/[ICAO]/parking.xml.  However, in order to be more flexible in 
developing scenery, we are currently working on moving a lot of data to the 
scenery tree. This consists of startup info, but also the ground networks, as 
well as a few other files related to AI (rwyprefs.xml). Because the latest 
release of FlightGear doesn't support reading data from the scenery tree, we 
are still providing limited support for adding ground networks to the base 
package.

With flightgear/CVS, you can choose which set of data to use, by changing the 
property:

/sim/use-custom-scenery-data 

Whenever this boolean property is set to false, ground network data will be 
read from AI/Airports/[ICAO], and when set to true, it is read from 
scenery/Airports/[I]/[C]/[A]/[ICAO].groundnet.xml.

Currently, this property controls the following:

- Reading of startup information: When set to "true",  the runway dimension 
data in apt.dat are overwritten by those in the scenery/Airports/[I]/[C]/[A], 
so that we have more flexibility in regenerating the terrain tiles without 
having to force the updated runway positions back into apt.dat.

- Use of ground networks
- the runway use files. 

Currently the /sim/use-custom-scenery-data property defaults to false.



Hope this helps,


Cheers,
Durk
