SYSTEM DESCRIPTION
1. General
The purpose of the TCAS 3000 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.
