Table 3-7: G5 and Supporting LRU Circuit Breaker Labels

Description
G5 (Attitude Indicator)
G5 (DG/HSI)
GMU 11
GAD 29/29B
GAD 13
[1] Circuit breaker is labeled "ATT" when the G5 is installed in the primary attitude
position. When an existing primary attitude indicator is retained the G5 installed in
the Turn Coordinator position should be labelled #2 ATT. Alternate spellings of
"ATT" is acceptable.
[2] When a single G5 is installed, the GMU 11 is powered from the same breaker as the
G5. When two G5s are installed, the GMU 11 is powered from the same breaker as
the G5 in the DG/HSI position.
[3] If a GAD29(B) is installed, the GAD 13 is powered from the same breaker as the
GAD29(B). When a GAD29(B) is not installed, the GAD 13 is powered from an
independent circuit breaker.
Cable and Wiring Considerations
3.4.5
Careful consideration must be given to the selection of wire type to be used for the CAN bus installation.
There are two types of wire approved for CAN bus installations as part of this STC, 120Ω CAN cable or
shielded twisted-pair cable, MIL-C-27500 (see Section 3.2.1).
It is recommended to use the 120Ω CAN cable for the following scenarios;
•
If CAN bus lengths are expected to reach the maximum allowed. (see section 3.4.5.2)
•
If there are future plans to install Garmin STC's SA01866WI, Installation of Garmin GFC 500
Autopilot with Electronic Stability and Protection or SA01899WI, Installation of Garmin G3X
Touch Electronic Flight Instrument System
If none of the above mentioned scenarios are a factor in the installation, use of shielded twisted-pair
cable, MIL-C-27500 is acceptable. Special attention should be given to section 3.4.5.2 for component
installation into the wiring harness.
For all other wiring selection considerations, select wire in accordance with AC 43.13-1B Chapter 11,
Sections 5 through 7. Mark wire in accordance with AC 43.13-1B Chapter 11 Section 16. Mark harness
connectors in accordance with AC 43.13 Chapter 11 Section 17. Install wiring in accordance with AC
43.13-1B Chapter 11, Sections 8 through 13. Record the aircraft wire routing in Appendix C of Garmin
G5 Electronic Flight Instrument Part 23 AML STC Maintenance Manual including Instructions for
Continued Airworthiness, P/N 190-01112-11. Use the following guidelines to prevent damage to the
aircraft and systems:
•
Do not route the wire harness near flight control cables, high electrical capacity lines, high-energy
sources or fuel lines.
•
Locate the wire harness in a protected area of the aircraft.
•
Make sure the wire harness does not come in contact with sources of high heat or be routed
adjacent to RF coaxial cables.
