In-Service Evaluation of the Traffic Alert and Collision Avoidance System (TCAS) Industry Prototype

摘要

An operational evaluation of the Traffic Alert and Collision Avoidance System (TCAS II) Industry Prototype was conducted to assess the utility of TCAS II to flight crews, to assess the impacts of TCAS on flight crew workload, to assess the impacts of TCAS on the air traffic control (ATC) system, and to obtain flight crew comments on TCAS design parameters and cockpit displays. The evaluation was conducted on one Boeing 727 aircraft operating in airline revenue service with Piedmont Airlines. Quantitative data on TCAS performance were collected to characterize the location and frequency of TCAS advisories. Qualitative data were collected from flight crews and cockpit observers to assess the impacts of TCAS on ATC and the flight crews. Minor operational anomalies the utility of TCAS and to assess were identified and changes to operational procedures or TCAS logic were recommended.
