Have just installed new compass in plane. My swing is out 30 degrees when positioned at 120 and 60. In reads true at east and west. Can it be changed without throwing out the magnetism of east and west?
N=340, 30=360, 60=30, E=95, 120=150, 150=180
S=210, 210=235, 240=250, W=273, 300=290, 330=315
I have read the casa bulletin from 2007. Adjustment in layman terms is required.
