I've been doing more hoodwork lately and have noticed that the compass heading on our D100 has (or has developed) a significant amount of lag/overshoot when changing headings.
It's almost as though the tape has inertia and when you roll wings level it keeps going at standard rate for a while and then swings back.
It's been a while since going through a compass rose calibration, but I am wondering if there is any feedback on this issue besides running through a calibration.
Previously I had trouble with the autopilot holding a heading. I believe that turned out to be mostly due to trim imbalance. After adding electric aileron trim, the plane flies straight on autopilot in HDG/TRK/NAV modes.
The current issue is easily reproduced by changing a heading at a standard rate turn or better and then rolling level fairly quick. If you slow your turn rate way down as you approach the heading, the lag is less pronounced with maybe a 1-2 degree overshoot. At Standard Rate you may see a 10 degree overshoot.
The remote magnetometer is mounted in the aft fuselage far away from any significant metal aside from the aluminum elevator pushrod and the rudder cables.
Thanks for any suggestions,
Morgan
