EXPERIMENTATION WITH REGAL VERTICAL GUIDANCE LANDING SYSTEM.
Abstract
Static and dynamic tests were conducted on REGAL (Range and Elevation Guidance for Approach and Landing), a vertically scanned microwave guidance system, to determine its suitability for use in an AllWeather Landing System. Areas of investigation included low-angle coverage, position determining accuracy, siting effects, noise content, scan rate, scan direction, method of signal coding, type of antenna pattern, weather effects, interference susceptibility, optimum flight path characteristics, etc. Aircraft using REGAL guidance information, coupled to various approach and flare couplers, were flown to touchdown using both manual and automatic control. Flight tests were conducted in a C-54G, Aerocommander, JC-131B and B-25 aircraft in both clear and adverse weather including rain, snow and fog with wind conditions varying from direct head winds to tail wind components of 20 to 25 knots. During the test program, more than 200 automatic landings were accomplished using various combinations of approach paths, flare paths and error signals. The results of these tests as well as design changes and future program requirements are discussed in this report. (Author)
