Graphical analysis of electromagnetic coupling on B-737 and B-757 aircraft for VOR and LOC IPL data

The objective of this paper is to analyze the IPL data measured, to better understand the impact on coupling levels based on the different locations of the aircraft radio antennas on the B-757 and B-737 airplanes, and to provide a basis for future fuzzy logic modeling of airplane IPL. This effort will build upon previous fuzzy modeling of IPL data for B-737 airplane data. Systems studied and compared include the instrument landing system localizer (LOC) and VHF omniranging (VOR) system.
