Selective Calling System

Call Panel

The Selective Calling (SELCAL) System monitors all of the communications radios. When the system receives a properly encoded call from a ground station, the crew is alerted through the illumination of the corresponding light on the pilots call panel.

Selective Calling (SELCAL) Messages

The communication crew alerting system also provides a supplementary method of notifying the flight crew about incoming calls from the cabin, ground personnel, or an incoming radio call. The •SELCAL message is a medium category alert. The flight crew should respond by establishing interphone communications with the calling station or transmitting on the corresponding radio. Added note regarding the ELT maintenance self-test function.
