Hi,I have the latest AS2004 MR2 B115 maintenance release and am experiencing wind shifts at high level, enough to give the aircraft overspeed warnings one minute, then the speed would drop below normal cruise speed and I get fuel warnings from the PMDG 737 FMC.According to the wind gauge, the wind direction and speed changed very little, but the speed tape gave me the impression that I had tailwind one second then headwind the next.I have seen numerous other threads relating to issues of this nature, and I thought the wind smoothing function in the new version of FSUIPC and AS2004 would stop this!!I have had these in the past, but only once or twice per trip, not as was the case last night when this occurred nearly every time the weather was updated.Any thoughts as to why these occur still?RegardsKeith

Hi Keith,You are right, B115 did not solve this, so we are still working things out. Right now we are 8 builds beyond B115. Just hang in there!Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg

Jim,Thanks for the update..I can live with it ;)regardsKeith

I did notice that the wind doesn't shift 180 degrees anymore.. It seems like it snaps around at 30 or 40 degrees at a time. I turned on wind smoothing on FSUIPC and had it limit changes to 1 degree every 2 seconds and this kept it from overspeeding the airplane, but it did result in almost constantly changing winds aloft.Keep up the great work!P.
