For no reason whatsoever, my aircraft show high airspeeds on the ground (Ground speed shows as normal and pitot heater on). Sometimes when I make a turn the aircraft crashes by tipping over and going through the ground and when I takeoff the aircraft rises almost vertically like a helicopter. Anybody else had this problem, before I re-install ?

Sounds like high winds to me. Check your global and local weather.Hope this helps,-- Tom GibsonCalifornia Classic Propliners: http://www.calclassic.com/Cal Classic Alco Page: http://www.calclassic.com/alco/Freeflight Design Shop: http://www.freeflightdesign.com/ San Diego Model RR Museum: http://www.sdmodelrailroadm.com/Drop by! ___x_x_(")_x_x___

Thanks for the feedback. I have now done a complete install and it is ok. The wind was n't the cause.

jerrycwo4A 'high ground speed' happen to me this morning but I just reinstalled the aircraft ( in the place where you select the aircraft to fly) and when it reinstalled, it was OK. Is this what you mean when you say you "reinstalled"? Are did you do a reinstall of Fs2002?jerry

Yes I did a clean complete install. The reason I did this aswell is so that I de-clutter some of the 'not so good' files that I have added. The only things that I save are 'my flights' and a few good aircraft. I have installed 'Ready for Pushback' 747-200, Dreamfleet 737-400 and Gary Summon's London Airports. Today I shall reinstall the Project AI aircraft. This problem started when I downloaded a 737 that uses the dreamfleet panel. That aircraft started the problem. I removed it but all of my other aircraft played up. I did ask if the author of the 737 file had a patch (in this forum),but I got no response. It was driving me nuts.Regards Nitram

jerrycwo4Sorry for your problems and I know that a COMPLETE reinstall is a MAJOR deal. I also know that the more 'items' that you install into FS2002, the MORE of a chance that things can go wrong. That why I ALWAYS use the "GO-BACK" program from "roxio" so I can 'fix' the problem if I catch it soon enough.jerry
