Cabin Address (GMA 1347D-20 only)
The CABIN Key initiates two way communication between the pilot or copilot and
the passengers in the cabin. The annunciator is lit when the cabin intercom is active
on either Audio Panel.
When the flight crew wants to communicate with the passengers, the pilot or
copilot presses the CABIN Key to signal that communication is desired. The cabin
signal must be acknowledged to begin intercom conversation.
When the passengers want to communicate with the pilot/copilot, they press the
“COCKPIT CALL” switch at their seat in the cabin. The CABIN annunciator flashes on
both Audio Panels to signal the pilot and copilot that cabin communication is desired.
The cockpit call signal must be acknowledged by pressing the CABIN Key to begin
intercom conversation.
PASSENGER ADDRESS (PA) SYSTEM
A passenger address system is provided by pressing the PA Key to deliver messages
to the passengers. The message is heard by the other pilot on the cockpit speaker
(if selected on) or on the headset if the PA Key is enabled on both audio panels. PA
messages are one way from the flight deck to the passengers.
