Compass Calibration

[brochinejr]

I am having some trouble with compass calibration. When I position my plane to "west" the skyview is trying to acquire the "south" position. Do you have any idea about what is causing the problem? How can I solve it?

This means the magnetic interference near your compass is so strong that it's off more than 45 degrees before you calibrate. This is too large of an error to calibrate out. You'll need to either move the ADAHRS or find the source of interference and move it.

What kind of plane is this and where is the ADAHRS?
