AUDIO PANEL FAIL-SAFE OPERATION
If there is a failure of both Audio Panels, a fail-safe circuit connects the pilot’s headset and microphone directly
to the COM1 transceiver and the copilot’s headset directly to the COM2 transceiver. Audio is not available on
the speakers.
If there is a failure of one Audio Panel, the remaining one does not have access to the others side’s COM and
NAV. For example, if the pilot side Audio Panel fails, the copilot side Audio Panel has access to all the radios
except for COM1 and NAV1.
