investigating Coupled autopilot is oscillating

[Krys06]

Hello,

 

I have a problem with the new coupled autopilot. It sometimes keeps oscillating around roll axis with an amplitude of plus or minus 5 degrees.

I tried to put a track file to show the problem. You need to advance it to around 16:47:30 "local time of the simulation". Sorry for the length of the track but I was unable to reproduce the behavior when I tried to do a shorter track...

On this provided track file, when I replay it, sometimes the oscillations are damped and reduce progressively but sometimes, the aircraft is continuously oscillating between around +5 and -5 degrees in roll without dump...
