A method and system for alerting a cockpit crew 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. The CDU may also optionally send a transponder code and an ACARS message to ground-based units.
