The international standardization of Airborne Collision Avoidance System (ACAS) is discussed in International Civil Aviation Organization. The work is now in a final stage after the recommendation by SICAS (SSR Improvements and Collision Avoidance Systems) Panel. To survey the effect of the system to the present ATC and aircraft operation system in Japan, The Collision Avoidance System Operational Survey Committee is organized. Civil Aviation Bureau, Universities, Airlines, Avionics Company, Defence Agency, and Electronic Navigation Research Institute participate to the committee.
The survey has three major objects. They are (1) Situation analysis of advisory generation, (2) Analysis of effects of Collision Avoidance System in such situations to ATC circumstances, (3) Operational issues to be solved. In this paper, (1) is mainly discussed.
In the survey, pilot and ATC comments are collected, and ground radar data are analyzed using those data. In this paper, the results of analysis of ground radar data are presented.
