Traffic Alert and Collision Avoidance System - Operational Simulation

摘要

This report describes one of a series of studies being conducted to develop the Traffic Alert and Collision Avoidance System (TCAS). The purpose of this study was to conduct a pilot evaluation of the relationship between TCAS displays, an operational crew station, aircraft performance, TCAS logic and operational TCAS procedures. The specific objectives of the evaluation were to be: Develop and evaluate the operational procedures associated with TCAS alerts under both normal and abnormal flight operations; Assess changes in flight deck operations associated with TCAS; Assess operational procedures as related to ATC control; Assess the impact of TCAS display requirements on flight deck systems and geometry. During the evaluation experienced transport pilots were presented TCAS alerts while flying a high fidelity B737-200 training simulator. Their response to the alerts was observed and recorded as were their opinions concerning the system. As a result of reviewing pilot responses to 552 TCAS encounters with a total of 970 intruder aircraft, it is recommended that TCAS be revised to achieve more consistantly correct pilot response.
