magnetic deviation


magnetic deviation
The angular difference between the magnetic heading and the compass heading, expressed in degrees east or west to indicate in which direction the end of the compass heading is offset from the magnetic heading. It is one of the errors in a magnetic compass caused by local magnetic fields in the aircraft especially by the “iron” of the aircraft. The error is not constant and depends on the “magnetic environment” and heading of the aircraft. This error is corrected by use of small compensating magnets, and any residual deviation is calculated during a compass swing and indicated on a compass deviation card.
