ACAS (Airborne Collision Avoidance System) was developed to prevent near-midair-collision. The operational evaluation for ACASII with vertical RA(Resolution Advisory) function has been conducted in Japan since 1990. It uses pilot reports, ATC(Air Traffic Control) comment sheets, on-board data of ACAS II aircraft and radar data. This paper presents the evaluation results based on pilot reports from January 1, 1995 to December 31, 1997. In the evaluation, the data written in pilot reports are classified directly and correlated each other. The principal component analysis was applied to make clear the tendency of pilot reports or the correlation of the items of pilots reports. For the analysis, we could obtain the combination of a high correlation of the items of pilots reports.
