ABSTRACT:
An electro-optical display system, particularly useful aboard aircraft carriers, is disclosed for remotely aiding a pilot in the landing of an aircraft. A conventional radar receiver continuously tracks the aircraft and produces a digital data signal indicative of aircraft slant range and elevation angle. The digital data signal is provided to a signal processor governed in accordance with either of a pair of control guidance algorithms to produce a control signal indicative of the magnitude and direction of an error in the appropriate descent rate of the aircraft. Based upon the control signal, a display driver produces a plurality of drive signals for energizing discrete light cells in vertically-oriented arrays as a visual indication of the descent rate error for appropriate corrective action by the pilot.
