REGAL TEST PROGRAM SUPPORT
Abstract:
The report presents the engineering results of the REGAL test evaluation program. The basic objective of the program was to determine the feasibility of the REGAL system, using an interferometer antenna, to provide airborne derived elevation angle and range data capable of providing accurate guidance for the purpose of landing aircraft. Comprehensive static and dynamic testing has revealed that REGAL has an elevation accuracy of 0.03 degrees for all angles 0.25 degrees above the mean ground plane and that the range techniques present the ability to approach within or - 50 feet or 1, whichever is greater, of the actual range. The latter part of the program was used to determine how well REGAL actually performed in a landing system. Over two hundred completely automatic landings were achieved using four different type aircraft, all equipped with different type landing computers and autopilots.
