Hello.I have a litte problem. If i fly plane in Airliner Pilot (dont know maybe it also happens in free flight) sometimes my plane is being heavily draggd off course ... meaning heading changes - autopilot turns back to heading it has ... airspeed jumps higher or lower and it really ####### me off. And if i set weather option to "clear all weather" it dosn't happen anymore. Also i have turbulance set off. Does anyone know how to get rid of it?Thank You.- PhOeNiX

this is wind. wind always 'blows' a plane off course ... just like in the real world.now, FS does have a fault in how it simulates wind direction and speed changes. FS will suddenly change the wind speed/direction when you move from one real-weather 'zone' to another. this change is not realistic and may result in wind direction and speed changes that will overspeed and/or knock the aircraft 'on its side'.there is no 'fix'. the situation can be improved by purchasing an addon weather engine (i use active sky 6.5 - AS 6.5). prior to purchasing AS6.5 i used the payware version of FSUIPC. FSUIPC has a 'weather smooting' functon that will reduce how fast FS can change the wind speed and direction ... limiting the problem you describe.--

Scoop, Thank You very much for You'r reply. I also own payware FSUIPC. I'll try it, and maybe also will give ActiveSky a shot.Thanks.- PhOeNiX
