Electrical Bonding
Make sure the transponder antennas are electrically bonded to the aircraft.
3.14
Cabling and Wiring
Use AC 43.13-1B chapter 11, sections 8 through 13 to install wiring. The considerations are as follows:
•
It should not be possible for the cable harness to be exposed to wire chafing.
•
The cable harness should not be located near flight control cables, high capacity electrical lines
(e.g., DC electric motor cables), or fuel lines.
•
Do not put cables near high energy sources (e.g., DC motors, high heat sources).
•
Wiring that must be shielded must be done as shown in appendix D.
•
Shield pigtail lengths must be less than 3.0 inches.
3.15
Electrical Bonding Considerations
Bond electrical equipment, supporting brackets, and racks to the aircraft’s main structure. Refer to SAE
ARP 1870 section 5 when surface preparation is necessary to get an electrical bond. Use a calibrated
milliohm meter to measure the resistance of the bond between the equipment and the adjacent aircraft
structure. The bond must have a DC resistance no more than 2.5 milliohms.
3.16
Cooling Requirements and Considerations
There are no cooling requirements or considerations for the GTX 35R/45R. The chassis has provisions for
a fan, however one is not necessary or provided.
