View Full Version : 5600 default heading error

I have just installed my 5600 in my RV7A and started it up. It's default heading is roughly 35 degrees from my whiskey compass. On the other hand I also have a Dynon D6 and its default heading is within a few degrees of my whiskey compass. Both the 5600 and D6 have their magnetometers on the same shelf (slightly seperated) at the top of the fuselage behind the baggage bulkhead. I believe that is as good a position as any on an RV7A.

At first I thought that my sliding canopy might be interfering with the 5600 magnetometer but when I closed the canopy the result was the same.

I have not tried calibrating the 5600 heading yet. Is it possible that calibrating the 5600 heading will correct an error of 35 degrees. My first thought is that I may have some other problem for the default heading to be so far off.

Any thoughts would be appreciated.

"I have not tried calibrating the 5600 heading yet"

You must do a magnetometer calibration with the canopy closed.
