Abstract: In order to provide timely aircraft performance data from an aircraft flight data recorder in a useful format, a flight data display system is provided: with a data storage unit; an interface circuit for reformatting flight data from the flight data recorder; a central processor for converting selected portions of the reformatted data into engineering units and storing the converted data into the storage unit; and a video display unit including a keyboard for selecting the desired portions of the reformatted flight data for display on the video display unit. The video display unit provides for the multicolor display of flight data in either graphical form or in a cockpit instrument form on a cathode ray tube.
