Hi, I had a problem which get me mad while crossing Atlantic this afternoon. I experienced a lot of huge changes in wind direction and speed. Since I left Ireland I could not have (almost never) a constant IAS speed, N1 value, wind direction and speed. In certain moments IAS speed dropped from 270 knots to 220!!! When reached that value four GE engines of my Jumbo rose up to the maximum thrust for 5 and more minutes to recover that gap. Then, when I reached 270knots, another wind direction change (sometimes for more than 80-90-120 degrees) and engines went to idle to decrease speed and then increased again, and then decreased again... and so on. I am very disappointed!Did anyone experience a similar problem? How did you fix it?I need a trick because every time I fly over Atlantic get this problem, but today was harder than in the past.Thanks bye.RR

FSUIPC has the best wind smoothing system available.

Yup, get a full version of FSUIPC and you will easily solve the problem.Al

I have the registered version of FSUIPC and still found this happening on a flight into SAEZ. The altimeter setting was jumping all over the place, it was hard to hold altitude. Only seen this once in my history of using FS. I guess it can happen sometimes depending on the data that's coming in to the weather utility (ASA, ASE, etc).

AS products for FS9 will work through FSUIPC for wind smoothing. Be sure they are set in there first. If that is not satisfactory then go into FSUIPC.Pages 12 - 15 in the FSUIPC user guide installed with version 3.93 in the modules folder might be of interest.
