When i am in the air with my pmdg 700/800 airplane it happens often that my speed suddenly change in 30 knots above it. What sometimes results in a overspeed. Then when the engine are reduced the to the input speed then the speed is suddenly 30 or 40 knots under it?? Beside that i notice that my airplane is shaking hard from the left to the right. It's like a hard rudder push.. It is not anti ice or the probe heat, because the switch is set to on.. Can someone please give me some advise about this issue? Best regards Christian

Hi Christian,Are you using Active Sky or another real world weather engine? That might explain the rapid speed changes. If you have the registered version of FSUIPC, you can adjust the parameters for wind smoothing so that the wind doesn't change as quickly.

ahh that is maybe the answer, because i fly always online at IVAO. Ther is an option in the module(wheather) to engage wind smoothing. I wil try if that works.Thx
