Features
The purpose of the TCAS (Traffic Alert and Collision Avoidance System) is to determine the range, altitude, and bearing of other aircraft equipped with Mode S/Air Traffic Control Radar Beacon System (ATCRBS) transponders, with respect to the location of own aircraft. It also monitors the trajectory of these aircraft for the purpose of determining if any of them constitute a potential collision hazard. The TCAS is responsible for estimating the projected intruder track and determining if a potential conflict exists. If so, the system displays an advisory to the pilot. The system also provides guidance for the optimum vertical avoidance maneuver. Complementary avoidance maneuvers between two TCAS equipped aircraft are ensured by coordination of mutual intentions with the other aircraft through the Mode S transponders.
