Hello,When I've tried to fly in formation with someone in VATSIM network (SquawkBox 3), I'm like getting some huge jumping effect, almost like a turbulence, but even worse. Later I figured out that something is heavily trimming the elevator up and down which then causes such effect. As I'm also using ActiveSky 2004.5, it might be some kind of a prop-stream simulation either by the AS or SquawkBox 3, because my friend, who uses the same software and who I tried flying formation with, experienced exactly the same. It's really very annoying and if some of you have an idea how to get rid of this, please tell me. Thank you!

Probably AS's attempt to replicate wake turbulence. Not sure how well AS does it, but if the problem dissapears when you are above the other aircraft then that is what it is.

Hi, Georg:Don't forget. You can always go into setup in AS and turn all wake turbulence off.Give that a try. I bet your problems will go away.Wilson

Thanks for the tips! I've never thought about this myself and I will try if it works.
