Cabin Address
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.
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 headset only if the
PA Key is enabled on both audio panels. PA messages are one way from the flight deck
to the passengers.
