  • Aircraft landing/taxiing system using lack of reflected radar signals to determine landing/taxiing area
    Patent number: 5736955
    Abstract: A system for displaying a landing/taxiing area as an aircraft approaches/taxis that landing/taxiing area. The system includes means on the landing/taxiing area that absorbs radar signals. The remainder of the landing/taxiing area reflects radar signals, and the system includes processors on board the aircraft or in the control tower for translating the signals and the lack of signals into a graphic representation of the landing/taxiing area. The representation changes as the orientation and position of the aircraft changes with respect to the landing/taxiing area. The system can include an autopilot control, head-up displays and memory systems. The system permits surface control by the tower.
