2.1.4 Installation Location
The G5 is installed in the pilot’s instrument panel in the primary attitude indicator location, in the rate-
of-turn indicator location, or in the DG/HSI location. The term “rate-of-turn indicator” refers to either a
turn coordinator or turn and bank indicator.
2.2 GMU 11 Magnetometer
The Garmin GMU 11 Magnetometer is a remote mounted device that interfaces with a G5 to provide
heading data to the G5 Attitude and/or G5 DG/HSI. The GMU 11 Magnetometer uses magnetic field
measurements to create electronically stabilized heading data. The GMU 11 is required when a G5 is
installed as a DG/HSI.

2.2.1 Installation Location
The GMU 11 installation location is determined at the time of installation as defined by the AML STC
installation data and recorded in APPENDIX B of this document and maintained with the aircraft
records. Installation is optional for the G5 as an attitude indicator and required for the G5 as a DG/HSI.
2.3 GAD 29/29B
The GAD 29/29B is a remote-mount unit that allows interface to IFR navigators such as the GNS and
GTN series. For installations with a G5 DG/HSI or a G5 DG/HSI and G5 attitude the GAD 29/29B will
receive ARINC 429 data from the navigator interfaced and transmit that information onto the CAN bus
to be consumed by the G5. The GAD 29B adds analog outputs and excitation pass through capability.
Installation is optional based on configuration of the system.
