Analysis of Active BCAS Alert Rates and Protection Based on Actual Aircraft Tracks

Abstract: : This document describes an evaluation of the performance of the Active Beacon Collision Avoidance System (Active BCAS) using the Houston data base and simulated midair collision scenarios. The Houston data was extracted from ARTS III tapes and consisted of 65 hours of operation. This data was used to measure alert rates and assess desensitization techniques aimed at reducing the number of unnecessary alerts. The midair data base consisted of the reconstructed flight paths of 15 actual midair collisions. Measures of protection and tradeoffs were made based on the performance of the BCAS logic in resolving these simulated collision scenarios. (Author)
