Abstract:

The study analyzes two collision avoidance systems CAS developed by Honeywell AVOIDS-1 designed for high performance aircraft and AVOIDS-2 designed for low performance aircraft. Both CAS were still undergoing refinements as of early 1973 therefore, the results reported here apply only to the specific versions studied. The two CAS use the Air Transport Association ATA collision avoidance logic and were evaluated in the 1971 FAA projection of traffic 800 aircraft in 1982 in the Los Angeles basin. No attempt was made to evaluate the operational suitability of the ATA logic in the projected traffic. The CAS are asynchronous and employ beacon interrogatortransponder techniques, which can lead to mutual interference among the CAS.
