Re: Autopilot, NAV and the DG



an OBS on a DG?
Does not match...
OBS on an HSI .. maybe..
and if you are in NAV.. the Autopilot should be correcting for drift
AND it is trying to track the bearing set to the OBS.. so of course it gets
upset when you change the OBS

When I'm on autopilot on NAV with my flight simulator (FlightGear) and I
adjust the OBS on the DG (correcting for drift), it upsets the autopilot:
it'll yaw off a bit and then go back. This is simulating a C172 with a
KAP140 autopilot.

Do real aircraft act like this or is it a bug?
