Hi. I am flying a new Jabiru with a D10 but nobody can seem to get the heading indicator to read correctly. Does it need calibrating. If so how do we do it, or is it something else. :'(
It does need to be calibrated. The exact procedure depends on whether or not you have the remote magnetometer installed or not, if that's an EFIS-D10A you have there. Check out the installation documentation for your product, available here.
