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.
