1.6.2 Cable Location Considerations
Use cable meeting the applicable aviation regulation for the interconnect wiring. Any cable meeting
specifications is acceptable for the installation. When routing cables, observe the following precautions:
• All cable routing should be kept as short and as direct as possible.
• Check that there is ample space for the cabling and mating connectors.
• Avoid sharp bends in cabling.
• Avoid routing near aircraft control cables.
• Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near
power for fluorescent lighting.
• Route the GPS antenna cable as far as possible away from all COM transceivers and antenna
cables.
