Garmin G5 Installation Manual page 31

GPS Antenna
3.4.1
A GPS signal is required. The G5 can use the Glare Shield Mounted GPS Antenna or GPS data from one
of the GPS navigators listed in section 5 or a GPS-enabled GTX 3x5 transponder.
In a dual G5 installation only, the G5 Attitude requires the GPS position input. The GPS information is
communicated to the G5 DG/HSI over the CAN bus.
If a GPS Navigator or a GTX 3x5 is used for a GPS signal, disable the internal GPS receiver of the G5. If
the G5 is connected to the Glare Shield Mounted GPS Antenna, enable the internal GPS receiver. See
Section 5 for configuration settings.
This STC only approves the installation and interface of the Glare Shield Mounted GPS Antenna,
P/N 011-04036-00. A TNC/BNC adapter is required to connect this antenna to the G5, adapter P/N
330-01754-00.
Considerations for Vacuum System
3.4.2
If a vacuum driven instrument is removed, the vacuum source must be capped and the system checked for
leaks. See the aircraft specific maintenance manual for procedure.
The vacuum system and associated parts may be removed if there is no remaining need for vacuum. See
the aircraft specific maintenance manual and AC 43.13-2B for guidance when removing the vacuum
system. If the vacuum pump is removed, the engine accessory port must be properly covered. See
specific engine maintenance and parts manuals for guidance.
Switches
3.4.3
There are no switches added by this STC installation.
Placards and Labels
3.4.4
All placards and labels should be readable in all lighting conditions. Ambient flood lighting is acceptable.
The new circuit breaker installed for the G5 unit and supporting equipment must be labeled as noted in
the interconnect drawings in Section 5. These labels are summarized in Table 3-7.
