What does STAR stand for in air traffic control?

The acronym STAR stands for Standard Terminal Arrival Route. This term is used in air traffic control to designate a pre-defined route that aircraft follow to transition from the en-route phase of flight to the approach phase, facilitating a safe and efficient arrival into busy airports. STARs are designed to optimize airspace use, reduce pilot workload, and minimize the need for vectors and instructions from air traffic controllers. By employing standardized routes, air traffic controllers can manage traffic flow better and ensure that arriving aircraft have a clear and predictable path to the airport. This system enhances safety and efficiency, particularly in terminal airspace where multiple aircraft are approaching simultaneously. Understanding the definition of STAR is essential for air traffic control operations and effective communication between pilots and controllers.
