Abstract: Various aircraft systems may benefit from enhancements that increase the reliability of the systems. For example, certain avionics systems may benefit from a distributed aircraft recorder system. A system can include an aircraft recorder on an aircraft. The system can also include a plurality of memory units on the aircraft and remotely located from the aircraft recorder. The memory units may be configured to receive streaming audio and flight data from the aircraft recorder.

Abstract: A system and method of streaming silence-edited audio data from an aircraft is provided. The European Union Aviation Safety Agency (EASA) has dictated that there needs to be a reliable way to recover data from channels recorded onboard an aircraft. The system and method include a silence editing unit which removes periods of silence from an audio signal and maintains a tracking of the time period during which the silence persists. Information of the time period during which the silence persists is transmitted, along with the silence-edited audio signal, via a streaming satellite signal, to be re-constructed at a reception end.

Abstract: A flight data recorder (FDR) may include a script engine configured to run an algorithm in order to obtain, analyze and use FDR and Cockpit Voice and Data Recorder (CVDR) data for non-Technical Standard Orders (TSO) applications. The script engine may be configured, by the algorithm, to analyze flight data received by the FDR and use the flight data to output a trigger via an Ethernet port or an ARINC 429 output. The script engine may also analyze the flight data and stream at least a portion of the flight data via the Ethernet port or the ARINC port.

Abstract: Flight data recorder receives from an aircraft a data stream specifying values for flight data parameters while an aircraft is in flight. The flight data recorder stores the values in a crash survivable non-volatile memory unit of the flight data recorder. The flight data recorder determines an occurrence during flight of an exception condition based on an evaluation of at least one exception parameter. Responsive to determining the occurrence of the exception condition, the flight data recorder wirelessly communicates selected aircraft data to a remote location external of the aircraft using a wireless transmitter under the exclusive control of the flight data recorder.

Abstract: Data recording systems and methods for synchronizing data of a plurality of different data types on a single packet. The methods involve: receiving the data and an audio frame containing voice data and timing data communicated over a plurality of channels; generating, in response to the reception of the audio frame, a combined packet on which the audio frame and at least a portion of the data are time synchronized to each other; and substantially simultaneously storing the combined packet in a primary data store and a secondary data store of a data recorder for subsequent use in reconstructing events leading up to a crash of a land vehicle, aircraft or vessel. The portion of data may include data link data, flight data and/or image/video data. The channels may include a cockpit channel and a plurality of pilot channels.
