  • Solid-state digital flight data recorder
    Patent number: 4409670
    Abstract: A digital flight data recorder receives sensed parameter information in serial data format in successive data frames and first circulates the information in a first-in first-out (FIFO) sequence through a minor memory to preserve the data received over a most recent real time interval, after which the data is compressed to a smaller data base including periodic slow interval samples and intermediate exceedance parameter samples which are stored in a major memory for later retrieval.
