3.13 Public Address Function
The Public Address (PA) can be activated through the ECAPS interface. The pilot microphone will be
heard on the speaker when the pilot PTT is used. The copilot can continue to use the selected com radio
while the pilot will now be heard over the speaker.
The C1 and C2 indicator LEDs will blink to indicate that the pilot is on the PA, and not on the intercom
or radio.
