Method for making an aircraft's voice and technical data secure during its flight stores transmitted voice and technical data in an external memory allowing the aircraft to land safely by remote control in the event of pilot inability.

摘要

Flight voice data from an aircraft (2) cockpit and aircraft technical data is sent to an external receiver (5) via a satellite radio link maintained during a whole flight's duration. Transmitted voice and technical data is stored in an external memory store (6). If a pilot is unable to fly the aircraft, the aircraft can be safely landed, because during the flight a satellite radio link between an airport (7) control center (8) and the aircraft is set up for remote control.
