My AI Traffic has no AFCAD Files inside .
Do you have GSX installed ? What's the AFCAD reported to be in use by GSX ?
It must be in your AFCAD File from KJFK
First, we should check if FSX is using that one. You can use the Simple Airport Scanner utility to see if you have any AFCAD duplicates that might be used by the sim instead.
Here you see the wrong Parking Positions .
I can only see your AI are parked wrong, but that's no indication the problem is the AFCAD, because we should first be sure the AFCAD in use is the one that comes with the airport. But even if it were, it's still not necessarily a problem of the AFCAD.
Some AI planes have their wingspan wrong, which was a method used by AI traffic packaged derived from FS9, in order to distribute to airline parkings, because FS9 didn't used airline codes. This is not needed anymore in FSX, but lots of models are still made that way, because nobody changed them.
But we'll check it anyway.
