Flying from RJTT-PHNL I have been experiencing drastic wind changes at cruise altitude about three hrs. into the flight causing the aircraft to overspeed one minute and stall the next, ultimately resulting in the aircraft crashing. I have tried this flight twice with the same results. I have wind smoothing enabled in both FSUIPC and AS. This is with FS9 and AS V6.5 build 522. Are there any other options in AS, FSUIPC or FS I need to enable/ disable to prevent this?Thanks.RPM.

I use FSUIPC to smooth winds (and pressure) such that the change is one unit (kt) per 5 sec. It helped, but the problem never goes away.

Hi,You should update to B552 from our web site.Thanks,Jimhttp://www.hifisim.com/banners/hifi-community-sigbanner.jpghttp://www.hifisim.com/

Sorry for the typo! I am using build 552.RPM.

Hi All,Please try with FSUIPC default settings and Weather settings Off.Thanks,Jimhttp://www.hifisim.com/banners/hifi-community-sigbanner.jpghttp://www.hifisim.com/
