Call System

The call system is used as a means for various crewmembers to gain the attention of other
crewmembers and to indicate that interphone communication is desired.

Attention is gained through the use of lights and aural signals (chimes or horn). The system
can be activated from the flight deck, either flight attendant station, or from the external
power receptacle. Passengers may also use the system to call an attendant, through the
use of individual call switches at each seat.

The flight deck may be called from either flight attendant station or by the ground crew. The
ground crew may only be called from the flight deck. Flight Attendants may be called from
the flight deck, the other attendant station, or from any passenger seat or lavatory. Master
call lights in the passenger cabin identify the source of incoming calls to the attendants.
