ELECTRONIC TERMINAL GUIDANCE FOR ALL-WEATHER VTOL OPERATIONS

Abstract:	THE REQUIREMENT for all-weather, VTOL terminal guidance is established. The recommendation for a first-generation, all-weather terminal landing system for the 1970’s is presented. The recommendation includes some aircraft characteristics as well as a combination of airborne and ground-based electronics which includes an autopilot with force stick steering, a self-contained radar guidance system and a microwave type of ILS/DME cooperative guidance system. The recommendation also includes terminal-based,, for dispersal equipment and a definition of visibility minimums. The system gives the pilot essentially “zero-zero” guidance capability. ,4 self-contained, perspective approach radar is described and results given. Developmental obstacles to all-weather landing capability are listed including: long lead times historically related to the multitudinous agencies involved in cooperative electronic systems (not necessarily self-contained), the meaning of redundancy, the role of pilot and co-pilot, etc. Many references are included for more detailed examinations.
