Hi,
How does the Challenger determine which airports are available in the FMS?
For EGNE, EGNC, EGBE I get a "NOT IN DATA BASE" message. They all exist in the CIFP folder and either have their own apt.dat in Custom Scenery or exist in Global Airports.
The only thing I can see linking them is the lack of ILS.
Edit: Although there are airports without ILS that do show up. I'm not sure what links them.
Thanks
