and make sure all your wires running to the buss are shielded. even the ground to the buss should be shielded.

Hello all,

I have a D-100 and am having problems getting a stable heading in a standard rate turn. I have installed the remote compass in the wing of my RV-9A with the Safe-Air kit. I have re-checked the angles of the mounting with a digital level and shimmed the remote compass to be within 0.1 degrees in one direction and 0.5 degrees in the other. I entered the inclination and other data in the d-100 and calibrated using the airport compass rose. The D-100 seems to give a pretty good heading when straight and level, but when I do any kind of a turn, such as a standard rate turn the heading leads or lags by as much as 30 degrees. This causes all sorts of problems including the autopilot performing oscillations in heading mode.

Has anyone had a similar problem and fixed it?
Thanks,

Bryan


Bryan,
Leading and lagging is usually caused by the inclination and / or total field numbers being wrong.
Read the instructions carefully on this page.
