Hi "Graysuit",I think Dann is politely telling you to sign your full name for eaching posting. This way you will usually get a quicker response. Question: Do you have any inbalance in the fuel tanks between left and right?RegardsMark

Hi Rob, Just curious, are you loading a saved flight? Or worse, a saved "Default" flight? I used to have this problem all the time when I ran a saved default but have cleared it up now that I no longer use them and always reset the panel state once in the sim to cold and dark.It sounds like a saved flight corrupt to me if the flight1 tool didn't help the other possibility.Hope this helps,

If you have Vista/W7, the registry tool needs to be run with admin rights.If that doesn't help, then turn off all the addon scenery by unchecking them in the scenery library manager (you don't have to uninstall). Bad scenery or AFCAD can cause this.

Thanks to all for kindly answer. First I didn't load a saved flight, and start my flight loading a cool and dark sets. Then I have executed Flight1 registry fix in admin mode. I have some doubts it could be a wrong AFCAD because the problem is present from different airports to other. The last test will be to reinstall all FSX.. maybe it would resolve problem.For your information I run FSX in W7/64bit. Let me know. Rob Parishttp://www.blueskyvirtual.com/BSV Virtual

Rob, strange as it seems, there are scenery 'bugs' that have global impact. The only other possible cause for tracking error is a bad magdev.bgl file in FS9 but FSX has implemented mag variance differently.

I was having the same issue. After take off and engaging LNAV the aircraft was making S turns trying to capture the LNAV path. I am using FSX default weather and FSUIPC with wind smoothing enabled. The fix for me was to disable turbulence effects in the FSX weather options. Even with a strong crosswind at cruise altitude, LNAV tracks perfectly now.Pesi Umrigar

Also I have FSUIPC smooth wind enabled. I will try to disable turbulence option and try again. ThksRob
