Title: Describe the role of TCAS in collision avoidance.
Course: Aircraft Pilot Training II (20053-II) > Section: Operating the Aircraft

Description should include the following:

- A traffic collision avoidance system or traffic alert and collision avoidance system (both abbreviated as TCAS) is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions (MAC) between aircraft.
- It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of ATC, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of MAC.
