Instrument Landing System Measurement Program

Abstract

Results of an extensive series of experiments to determine the characteristics and performance of the Watts slotted-cable, end-fire, glide- slope array are presented. Measurements made at the Tamiami ILS test site, specially prepared under this work program, show that the Watts array will produce a flyable path for Category I operations, but improvements are needed to give greater azimuth coverage of path information. Also, increased RF gain is needed to meet usable distance requirements when operating with solid state transmitting equipment. Image glide-slope systems and a slotted-cable localizer course array were also measured for performance characteristics and these items are discussed.
