HelloWhen i am flying in the PMDG 747, about 15 minutes in, the plane would start banking left and right. It would start small then the angle would increase gradually!When this happens i have the autopilot on.Why does it do this? Is there a way to fix it?Any help would be appreciated!David

Similar problem in this post. http://forums1.avsim.net/index.php?showtopic=2562041. Is it only banking or is it pitching up and down or is it doing both? 2. Is it banking non stop after 15 mins or is it occuring sporadically every now and then?3. Is the wind directions/speed changing rapidly while the problem is going on?4. Is turbulence and wind turned off? What happens when you turn it off in flight, does the problem change/stop?5. Is the weight and fuel configured correctly?6. At what altitude is it happening at and at which phase of flight?7. Is this only with the PMDG 747 or do you see the same or similar behaviour with other planes?8. Do you have any programs installed that might interfere?Take a few screenshots of the cockpit, DU's, fmc legs, perf init page etc. and let's see.

Yes it is similar to that post.I read what was said about the stock FS weather so i decided to set it to real world weather static instead of being updated every 15 minutes!Now i dont get any pitching during the flight.thanks for the help :)David
