A Standard Terminal Arrival Route (STAR) is a predefined flight path that aircraft follow when approaching an airport. It helps pilots navigate safely and efficiently from the en-route phase of flight to the terminal area. By using STARs, air traffic control can manage air traffic more effectively, reducing congestion and ensuring a smoother landing process. STARs are designed to streamline arrivals by providing specific waypoints and altitudes for pilots to follow. These routes are published in aeronautical charts and are essential for maintaining safe separation between aircraft. They are particularly useful at busy airports, where multiple flights may be arriving simultaneously.
