4.7 ABNORMAL OPERATION
Abnormal operation of the G1000 includes equipment failures of the G1000 components and failure of
associated equipment, including switches and external devices.
STUCK MICROPHONE
If the push-to-talk (PTT) Key becomes stuck, the COM transmitter stops transmitting after 35 seconds of
continuous operation. An alert appears on the PFD to advise the pilot of a stuck microphone.
The
COM1 MIC
or
COM2 MIC
Key Annunciator on the Audio Panel flashes as long as the PTT Key remains
stuck.

COM TUNING FAILURE
