Am I correct in assuming that I can transfer a custom AI configuration from one instance of FS2002 to another by copying the one file traffic.bgl over? (I know that I will need to ensure that the AI aircraft all appear in the new instance too, in the identical form as in the original, and as referenced by aircraft.txt).ThanksBruce.

Yes, it should work! I would think the easiest was to move the aircraft would be to copy the entire aircraft folder and move it to the other computer also. Note, the copy will overwrite identical files in folders that are identical. It should advise you when you copy.

Thanks, appreciate the helpful advice.Bruce.
