MICROWAVE LANDING SYSTEM INTRA-AIRCRAFT EMC ANALYSIS

This report discusses the electromagnetic compatibility of the Time-Reference Scanning-Beam Microwave Landing System (MLS) with other radiating systems on-board nine types of aircraft. These nine aircraft are the McDonnell Douglas DC-10, DC-9, DC-8, Boeing 747, 737, 727, 707, Lockheed Tristar L-1011, and the North American Rockwell T-39 Sabreliner. This MLS intra-aircraft interference analysis was performed by calculating the interference power level at a receiving antenna, comparing this power with a user-specified interference threshold, and identifying the potential problems. This report considers the TRSB MLS design as it was at the time the study was completed. Since that time a number of design changes have been made and are not addressed in this report. (Author)
