ABSTRACT:
A method and system for alerting an aircrew of terrorist activity in a cabin of an aircraft. The system includes a plurality of fobs worn by flight attendants. The system also includes an antenna sending unit (ASU) located within the cabin and a cockpit display unit (CDU) located in the cockpit of the aircraft. When a terrorist situation is detected by a flight attendant, the flight attendant sends an alerting signal to the cockpit by sending a coded signal via the ASU to the CDU. The CDU provides an indicator to the cockpit crew and an alert to each fob. In addition, the CDU sends a test signal to each fob to check the status of each fob.
