METHOD AND MEANS FOR PROVIDING A SYNTHETIC REAL WORLD RUNWAY CENTERLINE DISPLAY

摘要

A system in an aircraft for displaying a perspective view of a synthetic runway centerline on a cathode-ray tube in a heads-up display system for guiding a pilot while landing an aircraft on the real world runway at an airport when visibility is poor. The perspective of the synthetic runway centerline changes in accordance with changes in the position of the aircraft to the runway at the airport. Beacons located at each end of the runway's centerline provide signals to a receiver in the aircraft. The receiver provides signals corresponding to the positions of the beacons. A signal generator provides deflection voltages for a synthetic runway centerline display to a computer which modifies the deflection voltages in accordance with the signals from the receiver. The cathode-ray tube provides the perspective synthetic runway centerline display in accordance with the modified deflection voltages.
