Traffic Alert and Collision Avoidance System (TCAS)
The Traffic Alert and Collision Avoidance System (TCAS) is an aircraft safety feature designed to prevent mid-air collisions. It monitors the airspace around an aircraft using transponder signals from other nearby planes. If it detects a potential threat, TCAS provides alerts to pilots, giving them instructions on how to avoid a collision. It can indicate whether to climb or descend and also displays relevant information about other aircraft's altitude and distance. By enhancing situational awareness, TCAS significantly improves flight safety in busy airspace.
