1.6.1.12 G5 Attitude CAN BUS Interface Summary
The G5 Attitude indicator can utilize CAN BUS connections when specified by a specific
equipment configuration to allow heading information from the GMU 11, communication of
navigation data from the GAD 29/29B and communication between the G5 Attitude indicator
and the G5 HSI.
For specific wiring information refer to Section 5.
1.6.2 G5 DG/HSI Indicator
The G5 Electronic Flight Instrument configured as an HSI, is shown in Figure 1-3. The G5 is
an electronic instrument display operating as a standalone flight display. It features a bright,
sunlight readable, 3.5-inch color display which is sized to fit in a standard 3-1/8-inch
instrument cutout. The G5 contains integrated attitude/air data sensors that provide a backup
display of attitude and air data information. The G5 has battery backup and in the case of
aircraft power loss will sustain G5 operation with up to 4 hours of emergency power. When the
G5 is installed as a DG/HSI the battery backup is optional.

The Garmin G5 indicator can replace an existing vacuum-driven or electro mechanical
DG/HSI. In this location the G5's primary function is the display of slaved compass, #1 VHF
NAV and/or #1 GPS NAV. The possible configurations for a G5 DG/HSI are discussed below.
(Note: The VHF navigators and GPS navigators interfaced by this STC are not installed by this
AML STC. Only the interface of the VHF NAV, GPS NAV and G5 Attitude and G5 DG/HSI
are approved with this STC.)
1.6.2.1 G5 Slaved DG
The basic installation is a G5 in the DG indicator location and a GMU 11.
•
In this configuration the G5 is installed as a slaved compass with no NAV information.
•
The G5 DG can be used as a backup Attitude/Airspeed/Altitude Indicator.
