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.
