COPILOT CONFIGURED AS CREW OR PASSENGER

NOTE: When the copilot position is conﬁgured as a passenger, the COPLT Key is disabled and the copilot

headset is treated as a ‘passenger’ for intercom and entertainment audio distribution.

The copilot position can be conﬁgured as crew (COPLT Key enabled) or as a passenger (COPLT Key

disabled). Pressing and holding the COPLT Key toggles the copilot position conﬁguration between passenger

and crew. The aural message “Copilot Conﬁgured as Passenger” or “Copilot Conﬁgured as Crew” is

heard.

INTERCOM MODES

NOTE: In the following modes the copilot position is conﬁgured as crew.

NOTE: In the default ICS conﬁguration, only the pilot and copilot positions can hear aircraft alerts.

NOTE: When in Split-COM mode, the copilot will only hear alerts and the higher numbered of the two

selected COMs (COM2 or COM3).
