Demonstration of a precision runway monitor system to increase landing capacity of parallel runways

Summary form only given. A development and demonstration project has been conducted to increase landing capacity on closely spaced parallel runways. The project developed new equipment and procedures, and demonstrated them in a variety of ways at two different airports. The monitoring equipment consists of radars and displays. The system installed at Raleigh, NC included an electronically scanned antenna capable of half-second update intervals, while the Memphis, TN installation provided a mechanically rotating back-to-back antenna with a 2,4-s update interval. In addition, both sites provided enhanced high-resolution color ATC display systems. Particular attention was given to a decision concerning whether or not the current standard for runway separation at 4300 feet can be reduced when the precision runway monitor equipment is utilized. The author recommends accuracy, update rate, and display requirements for the PRM (precision runway monitor) radar.<>
