Enhancements to the next generation collision avoidance system: opportunities for greater safety and efficiency

Abstract

The next generation of the airborne collision avoidance system, TCAS IV, will improve upon the present TCAS II in several respects. In making use of accurate satellite-based position data and air-to-air data link of intent, TCAS IV will support superior collision threat detection and resolution. Operational applications making use of cockpit-displayed traffic information should facilitate more efficient and flexible flight.
