For satisfactory results, all extraneous magnetism causing over 30-35 degree compass errors should be removed from the aircraft, or the compass should be relocated to a position where uncompensated error does not exceed 30-35 degrees. Use a brass or other non-ferrous material screwdriver when making compensator adjustments. Best results can be obtained in actual flight compensation by following the procedure outlined below: • A. Set directional gyro from a sectional line or runway. (Allow for magnetic variation to ensure gyro corresponds to magnetic heading) • B. Follow procedures 1 through 6 above. Re-check directional gyro occasionally for possible precession, and allow for such precession error in recording results on magnetic compass deviation card.
NOTE: If aircraft is equipped, GPS can be used (allow for deviation) to establish reference headings for compass compensation. This technique will eliminate possible errors caused by gyro precession.
