Abstract
An aircraft has a passenger cabin security alert system for alerting authorised personnel (flight crew) in the flight deck to a problem in the passenger cabin. The system employs portable wireless transmitter units suitable to be carried or worn on the person of authorised personnel (cabin crew) in the passenger cabin. Each transmitter unit is adapted to transmit a warning signal when actuated that is received by detector units that communicate with control means operable to determine the position P in the passenger cabin of the transmitter unit that has been actuated. The control means activates an alert unit in the flight deck to indicate the existence and position of the problem to authorised personnel (flight crew) in the flight deck.
