3.3.8 Automatic Fail-safe
In the event of a power failure, automatic fail-safe operation will be activated. This
routes the pilot’s phones, mic audio, and mic PTT directly to the COM radio. Copilot and
passengers will have no ICS, music, or receive functions.
The pilot mic is directly connected to the transceiver mic. Mic bias is provided by the
transceiver, not the AA83-100. The pilot TX keyline is directly connected to the
transceiver.
During receive mode, receive audio is directly connected from the audio source to the
pilot phones, and during transmit mode, the sidetone audio is directly connected from
the audio source to the pilot phones. In both cases, copilot and passengers have no
ICS, music, sidetone, or receive functions.
In the unlikely event of an AA83-100 circuit failure that results in a communication
problem, the automatic fail-safe mode can be enabled by pulling the AA83-100 circuit
breaker.
Note : In Automatic Fail-Safe mode, the receive/sidetone levels may require adjustment
at the audio source.
The pilot should confirm that all aspects of Automatic Fail-Safe operation are
working before accepting the aircraft into service.
