PASSENGER ADDRESS (PA) SYSTEM
Press the PA Key to deliver messages to the passengers. The message is heard by the other pilot on the headset
only if the INTR COM Key is enabled. PA messages are one way from the flight deck to the passengers.
A Push-to-talk (PTT) must be pressed to deliver PA announcements to the passengers over their
headphones.
When PA is selected on the Audio Panel, the annunciator flashes about once per second while pressing the
PTT, the COM MIC annunciator is no longer lit, and the active COM frequency for that Audio Panel changes to
white, indicating that there is no COM selected.

SIMULTANEOUS COM OPERATION
Both the pilot and the copilot can transmit and receive simultaneously over separate COM radios. The
selected COM MIC Annunciator flashes when either pilot’s microphone PTT is pressed.
If both pilots select the same COM radio, the pilot has priority on COM1 and the copilot has priority on
COM2.
