Abstract:

The study is an analysis of how well RCAs aircraft collision avoidance systems, known as the SECANT VECAS and the SECANT VECAS-GA, will perform in the high-density traffic forecast for the Los Angeles Basin in 1982. The evaluation is based on the threat logic of ANTC-117. The RCA equipment, consisting of reasonable assumed mix of VECAS, VECAS-GA, and a proximity warning indicator in its present design configurations, meets the relevant specifications and otherwise conforms to the intent of ANTC-117. Some minor difficulties remain, the most significant of which is the possible delay in tracking one of two targets with nearly the same range. However, these are not expected to cause any serious design problems. Also, VECAS-GA should be provided with 32 rather than 16 trackers for operation in high-density traffic. The system now appears to have some growth potential, and further improvements, leading to performance somewhat beyond that required by ANTC-117, seem possible.
