An Airborne All - Weather Landing System Using Flarescan - ILS Guidance 620382

This paper discusses operation of the Flarescan controller used by the FAA as part of the program to evaluate the Flarescan guidance system for all-weather landing. A throttle control system compatible with Flarescan is described.
Simulation studies of the basic system parameters such as transmitter location, glide slope angle, scan rate, winds, beam noise, and early and late flare engagements are also presented. A flight test evaluation of Flarescan and the problem areas discovered in this test are discussed. Changes in coupler design are proposed, to reduce the dispersions due to the variations in system parameters.
