In some Addon airports (Simflyers-KPHL or Mice LSZH) Ai aircrafts taxi in the air above aprons and taxiways...At most of the other Addon places, they roll (stay) on the floor.Does somebody knows what's going on ?Help appreciated

I've seen comments that there are difficulties where runways are sloped in add-ons and non-tolerance of FS2K2. Don't know about FSCOF.

Are these default AI aircraft, or add-on aircraft? Sometimes, an add-on aircraft will hover off the deck a little bit when you are in slew mode. This is due to settings in the aircraft.cfg file. When the AI aircraft are initialized at an airport, they use this same setting, at least until they start up.If the aircraft are actually taxiing this way, it maybe due to the difference in altitude between the add-on scenery and the AFD file.- Martin

Yup....I think it's a case of waiting for Afcad 2004 so one can change the altitude of the Addon airport in the ADF file.regardsEdhttp://forums.avsim.net/user_files/33170.jpg
