button. ALL mode is active when neither PILOT or CREW have been
selected.
The following table shows, in abbreviated form, what each occupant
hears in each of the selectable Intercom modes:
Marker Beacon
The Marker Beacon Receiver provides visual and audio indicators to
alert the pilot when the airplane passes over a 75 MHz transmitter.
Marker beacon controls and lights are located at the extreme left of the
Audio Control Panel.
PILOT
The pilot is isolated from the intercom. The pilot can hear
radio and sidetone only during radio transmissions. Copilot
and passengers can hear the intercom and music but not the
airplane radio receptions or pilot transmissions.
CREW
Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. They may also
listen to Music1. Passengers can continue to communicate
with themselves without interrupting the Crew and also may
listen to Music2.
ALL
All parties will hear the aircraft radio, intercom, and Music1.
The music volume increases gradually back to the original
level after communications have been completed. Both pilot
and copilot have access to the COM transceivers.
