Traffic Collision Avoidance System (TCAS)

Traffic Collision Avoidance System (TCAS) is an onboard safety system in aircraft that helps prevent collisions with other aircraft. It constantly monitors the airspace around the plane using transponder signals. If another aircraft is detected and gets too close, TCAS issues alerts to the pilot, recommending whether to climb or descend to maintain safe separation. The system provides clear, actionable commands when a potential collision risk exists, helping pilots make timely decisions to ensure safety without relying solely on air traffic control.
