problem
Posted: Thu Jan 25, 2007 1:00 pmHi, I'm here new!!!! I have a problem about my aircraft.cfg file I can't find it!!!Please help!!! 
Hi and welcome to Simv.
I don't think they are 'hidden' files, so that souldn't be the problem.
It should be in the planes folder.
Look in the main Aircraft folder and then the folder of the plane you want.
FS9 main folder\Aircraft\c172 for example. In the c172 (and all other planes) you should find the Aircraft.cfg for that plane.
I hope this helps.
