2.4.1 Cable Routing Considerations

When routing cables, observe the following precautions:

•

All cable routing should be kept as short and as direct as practical.

•

Avoid sharp bends.

•

Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near

power for fluorescent lighting.

•

Avoid routing antenna cables near ADF antenna cable (allow at least a 12-inch separation).

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:

1. Obtain approved antenna installation design data from the aircraft manufacturer.

2. Obtain an FAA approved Supplemental Type Certificate (STC) pertaining to and valid for the subject

antenna installation.

3. Contact the FAA Aircraft Certification Office in the appropriate Region and request identification of

FAA Designated Engineering Representatives (DERs) who are 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.

Antenna installation in the pressure vessel of pressurized aircraft is beyond the scope of the GTX 32 STC.

Additional manufacturer's data may be necessary and FAA approval may be required to cover the

installation of the antenna.

2.6

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.

A 5/8 inch air fitting is provided on the rear of the backplate for the purpose of admitting cooling air

under such conditions. If a form of forced air cooling is installed, make certain that rainwater or

condensation cannot enter and be sprayed on the equipment.
