First off, AIFP is a great improvement over the FSX SDK traffic tool. After sorting through the problem of FS9 traffic.bgl's "poisoning" the FSX compiled files, Ive run into a problem I'm stumped by. I have created several working flightplans with some FSX default planes but others simply won't show up, no matter what. The ones that I have tried and can't get to "show" are the C-172, Maule, Goose and DC-3. Any ideas as to what would cause this?
