A spare voice channel on a cockpit voice recorder (CVR) is used to record flight data. Data from an accelerometer and other sensors in an aircraft are digitized and collected by a microprocessor once each second and are collated and arranged in an industry standard format, and an encoder converts the formatted data into an industry standard code for recording on the CVR. During transmission of data to the CVR, fresh data is collected for the next transmission.

A system for recording aircraft flight data developed by instruments comprising: a cockpit voice recorder having a plurality of audio channels, at least one of the audio channels being a voice channel for the recording of cockpit voice communications and one of the channels being reserved for data; means for collecting flight data from the instruments; a microprocessor for receiving collected flight data and for serially presenting the collected flight data in an organized format; means for encoding and scaling the formatted data and transmitting the scaled encoded data in a voice frequency band to the cockpit voice recorder; and means for recording the transmitted data on the reserved channel of the voice recorder separately from the cockpit voice communications.
