When I try to use a "multiple airport" apt.dat in TerraGear with "All Airports within area" or All airports in an apt.dat file" selected, only a few of the airports are generated and appear in the AirportObj directory, yet I get the full "100%" success bar displayed in TerraGear. I have tried the uncompressed apt.dat that comes with FlightGear (apt.dat.gz) and it, too, generates many, but not all airports. Do the "All Airports within area" and "All airports in an apt.dat file" work or is it necessary to generate each airport individually?
The airport files I've tried in TerraGear have passed validation before being exported. My goal is to generate a new apt.dat, with recently downloaded X-Plane Scenery Gateway airports, then generate the scenery.
Any suggestions as to why this is not working properly will be greatly appreciated. Thank you.
