Communication Crew Alerting System
As installed
The Communication Crew Alerting System is a method of notifying the flight crew about incoming calls from the cabin, ground personnel, or an incoming radio call by displaying messages on the EICAS system.
The Communication Crew Alerting System provides aural and visual alerts for normal operations requiring crew awareness that may require crew action. Visual alerts are presented as white lettered EICAS messages preceded by a white bullet symbol (•). The aural alert is a single chime. The flight crew should respond by pressing the corresponding switch light (alert, cabin or ground) on the pilot's call panel and establishing interphone communications with the calling station.
