THE DESIGN, DEVELOPMENT, AND FLIGHT TEST RESULTS OF THE BOEING 737 AIRCRAFT ANTENNAS FOR THE ICAO DEMONSTRATION OF THE TRSB MICROWAVE LANDING SYSTEM

The Research Support Flight System, a modified Boeing 737, was used to evaluate the performance of several aircraft antennas and locations for the Time Reference Scanning Beam (TRSB) Microwave Landing System (MLS). These tests were conducted at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, New Jersey on December 18, 1975. The flight tests measured the signal strength and all pertinent MLS data during a straight-in approach, a racetrack approach, and ICAO approach profiles using the independent antenna-receiver combinations simultaneously on the aircraft. Signal drop-outs were experienced during the various approaches but only a small percentage could be attributed to antenna pattern effects. (Author)
