Have a D10A installed as backup AI w/out external compass EDC-10A (confirmed by headset test) - using Skyview as primary. I need to recalibrate the D10A as the mag heading is off by quite a bit.
In the manual it mentions the first step is to input inclination and intensity, however, it also says this must not be repeated if moved (e.g. in my case, I purchased the plane and moved it to a neighboring state).
When I enter the menu - more--setup--more--more - MAGINC isn't even an option. I assume this is because it has already been done and is not needed? I was trying to input to ensure the correct data was initially used, but am unable to find/select MAGINC. MAGCAL is available, which results in a menu that reads GNDNRT, AIRRGT, and AIRLFT, further confirming not having the external compass.
I've just recently been playing close attention to the D10As heading indication, so I don't have much trend info, but the error seems to vary - sometimes on the ground it matches the skyview, but in flight off by 30-40 degrees. What initially made me pay close attention was noticing that many times in level flight, the D10A indicated a left bank of several degrees. This was much more obvious from cross-cockpit than the heading direction, which I noticed after paying closer attention to the instrument. Maybe a sign of a failing instrument...?
