Test Equipment; Installation Considerations - Garmin G5 Installation Manual

3.3 Test Equipment

The following test equipment is required to complete the G5 installation and to perform post-
installation checkout of the system:
•
Ground power cart (capable of supplying power to the aircraft systems and avionics)
•
Air data test set (e.g. Barfield DPS450 or similar)
•
VHF NAV test set
•
Low resistance ohmmeter
•
Digital Level (or equivalent)
The following equipment may be required based on the units being installed and the particular
aircraft, see Section 4.1 for information:
•
Laser Square
•
Protractor Tool
•
Plumb Bob
•
Aircraft Jack Set

3.4 Installation Considerations

The installation instructions are intended to be used in coordination with the avionics
installation practices in AC 43.13-1B and AC 43.13-2B.
•
Modification of existing plastic instrument panel overlays may be required to install the
G5 electronic flight instrument.
•
Fabrication of a wiring harness is required.
•
Sound mechanical and electrical methods and practices are required to achieve
optimum system performance.
3.4.1 GPS Antenna
A GPS signal is required. The G5 can use an external GPS antenna or GPS data from one of the
GPS navigators or GTX 3x5 listed in Section 5.
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 an external GPS antenna is connected to the G5, enable the internal GPS receiver.
See Section 5 for configuration settings.
This STC approves the interface to antennas shown in Table 3-7 and Table 3-8.
This STC does not approve the installation of a GPS antenna. A separate airworthiness
approval for antenna installation is required except for existing or previously approved
installations. One means of installation approval is Garmin Antenna STC SA02018SE-D
for mounting GPS antennas.
Other antennas that meet the specifications listed in Table 3-9 will work with the G5, but it
is the installer's responsibility to ensure that their choice of antenna meets FAA standards
according to this specific installation.
