Calibration Procedure E: Magnetometer Interference Test
A magnetometer interference test is available for troubleshooting and/or verifying a magnetically 'clean'
installation of the GMU 44. This test exercises various devices on the aircraft that could potentially
affect the magnetic field as measured by the GMU 44.
This test is used to validate that no electronic device interferes with the operation of the
GMU 44 magnetometer. It is highly recommended that this test be performed after
installation or maintenance of electrical components on the aircraft and/or for
troubleshooting the GMU 44.
1. Initiate the AHRS magnetometer interference test procedure by performing the following steps:
2. On PFD1, enter Configuration Mode and go to GRS/GMU Calibration page as shown in Figure
