Abstract : A Microwave Runway Perspective Independent Landing Monitor System was evaluated in flight test in a DC-7 aircraft at the National Aviation Facilities Experimental Center, Atlantic City, New Jersey. The system utilized eight microwave transmitters spaced in a pattern along Runway 13. Passive airborne equipment received pulses from these transmitters and displayed the video on a head-up viewer. The system was found to be highly susceptible to multipath reflections which caused a rapid display jitter. This problem was greatly reduced by the addition to the airborne equipment of a signal smoother. It was also found that the accuracy of usage of the basic display was unacceptable and that aiding symbology would have to be added to the display to improve accuracy of usage. (Author)
