5、 the aircraft is pointing during flight. The angle between the course and the heading. Can be calculated on E6-b before the flight Angle between true north and magnetic north. Isogonic Lines - Lines drawn across aeronautical charts to connect points having the same magnetic variation. Agonic Line 0 isogonic line, no variation Magnetic compass error caused by local magnetic fi elds within the aircraft. It is different on
