Flight recorder for selectively transmitting flight data from an aircraft
The described features generally relate to a flight data recorder system for adaptively transmitting flight data from an aircraft. In particular, an aircraft may collect flight data from a first set of aircraft sensors. This collected flight data may then be transmitted from the aircraft by a communication terminal of the aircraft. A flight data communication scheduler may manage the selective transmission of the flight data from the aircraft, and monitor flight parameter values associated with the flight data collected from the first set of aircraft sensors. An indication of a trigger event may be obtained, and a second set of one or more aircraft sensors of the aircraft may be activated to collect additional flight data associated with the second set of sensors. A ground station may perform aspects of adaptively transmitting flight data from an aircraft, and store flight data in a ground-based flight data recorder.
