2.5 Installation Approval Considerations for Pressurized Aircraft
Antenna and cable installations on pressurized cabin aircraft require FAA approved installation design and
engineering substantiation data whenever such installations incorporate alteration (penetration) of the
cabin pressure vessel by connector holes and/or mounting arrangements. Use of existing bulkhead
connectors previously approved by other means is permissible without additional approval.

For needed engineering support pertaining to the design and approval of such pressurized aircraft antenna
installations, it is recommended that the installer proceed according to any of the following listed options:

authorized to prepare and approve the required antenna installation engineering data.
4. Obtain FAA Advisory Circular AC-183C and select (and contact) a DER from the roster
of individuals identified thereunder.
5. Contact an aviation industry organization such as the Aircraft Electronics Association and
request their assistance.
2.6 Cooling Air
Cooling air is generally not required. However, if the unit is located in a confined space or near a source of
heat, cooling air is recommended for maximizing the life of the GTX 3000. A 5/8 inch air fitting is
provided on the rear of the backplate for the purpose of admitting cooling air. If a form of forced air
cooling is installed, make certain that rainwater or condensation cannot enter and be sprayed on the
equipment.

2.7 GTX 3000 Mounting Requirements
Refer to the G1000 System Installation manual, Garmin part number 190-00303-00, for information on
cooling requirements. For remote mounted units, forced air cooling is not required. However, the
application of forced air cooling is recommended to provide beneficial cooling if the unit is located in a
confined space or near a source of heat.
