Standard Terminal Arrival Routes (STARs) are predefined flight paths that guide aircraft from the en-route phase to the approach phase of landing at an airport. These routes help manage air traffic efficiently, ensuring that planes arrive safely and in an organized manner. STARs are designed to streamline the transition from high-altitude flight to lower altitudes, reducing congestion in busy airspace. Pilots receive STAR instructions from air traffic control, which include specific waypoints and altitudes to follow. By using STARs, airlines can optimize fuel consumption and minimize delays, contributing to a smoother travel experience for passengers. This system is crucial for maintaining safety and efficiency in the aviation industry.
