15.4 Unit Installation

The following guidelines describe proper mechanical installation of the Garmin GMU 22 Magnetometer.
The guidelines include requirements for proper location selection in the aircraft, requirements for
supporting structure and mechanical alignment and restriction on nearby equipment.
Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are
required for installation of the GMU 22. Refer to
for pinouts.
The GMU 22 is an extremely sensitive three-axis magnetic sensor. It is more sensitive to nearby magnetic
disturbances than a flux gate magnetometer. For this reason, when choosing a mounting location for the
GMU 22, observe the following distances from objects or devices that can disturb the magnetic field.
Table 15-4 specifies recommended distances from magnetic disturbances for GMU 22 location.
NOTE
If the requirements listed in
must be performed to ensure proper operation of the G3X system. Refer to the AHRS/
Magnetometer Installation Considerations document (190-01051-00) available from the
Garmin website
