RNAV & autopilot oscillation
-
I've been really enjoying using the RNAV511 system but for one issue.
When I am tracking a RNAV radial using the autopilot in NAV mode, I've noticed that the autopilot oscillates in a very regular fashion and it's offputting in the cockpit, inducing a mild dizziness. The autopilot is presumably correcting for wind, but it does it abruptly 1 degree every second. You can see the yoke move to the right, straighten up, then move to the right ad infinitum. If I switch it over to HDG mode, there is some correction, but it's much smoother and less frequent. Similarly, I haven't noticed this oscillation if I'm using NAV mode direct to/from the real VOR station.
Is this real life behaviour of the autopilot?
