Airborne Collision Avoidance System (ACAS)

The Airborne Collision Avoidance System (ACAS) is a safety feature used in aircraft to prevent mid-air collisions. It monitors the airspace around the plane and detects other aircraft nearby. When it identifies a potential collision risk, ACAS issues alerts to pilots, advising them to change altitude or trajectory to avoid the threat. This system works automatically, providing crucial information in real-time, helping enhance flight safety by allowing pilots to make informed decisions to maintain safe distances from other airplanes.
