What does the acronym TCAS stand for?

The acronym TCAS stands for Traffic Collision Avoidance System. This system is crucial in aviation as it enhances safety by providing pilots with information about the proximity of other aircraft. TCAS works by monitoring the airspace around an aircraft, using transponder signals from nearby aircraft to assess potential collision threats. If a potential conflict is detected, TCAS will issue alerts to the flight crew, indicating whether they should climb or descend to avoid a mid-air collision.

The other options do not accurately represent the established terminology used in the aviation industry for this life-saving system. Understanding that TCAS is a widely recognized safety mechanism helps reinforce the significance of effective air traffic management and collision avoidance in maintaining flight safety.
