Hello guys. Past two flights i've had a really wiered problem. The airplane will randomly just change it's speed from like 260-310 knots instantly, and then after a few seconds it'll jump to 240, then back up to 280, and so on. The time between the jumps varies, and sometimes after a few jumps the speed stabilizes itself at the assigned MCP speed. At some points the speed kept constantly jumping from 245-250 for like 5-10mins straight, my whole approach phase basically. It can happend in any phase of the flight. I have no clue as to why this happends. Anyone who could shed some light on this? Cheers

Do you have used active sky or another external program for weather? There is a problem in Fsx, you must set your weather trough FsuiPC to avoid that

I use REX for weather, though i've been expiriencing this issue before i installed this addon. I just realised a moment ago that i don't have turbulence and thermal effects disabled in FSX. Ill try disabling it.

Thanks man - Arthur

I haved a same problem, seems to be a common problem with external weather programs(ASE, REX, Open Clouds).
