ABSTRACT:
A magnetic compass calibration system used in areas of magnetic disturbance. The invention allows the aircraft to remain in the hangar or hangar area while the aircraft's compass is compensated. The invention compensates for time variances in ambient magnetic field, as well as magnetic variances caused by hard and soft iron found in the hangar area, ramp area or aircraft.
