Hmm well my AES is legal, so I don't think I will be deleting that ::)
Still no joy.
Oh well, I can still perform a full flight in the 747-400.
Can't think of what the problem could be, and I've tried a re-install. Maybe it's something do do with the AP system? Can anyone think what might be changed in the AP when passing through 20,000'ASL? When it crashes I am not doing anything in regards to altering the autopilot or FMC, so maybe its a AP process?
Hmm..
