What does a STAR chart specifically help with in air traffic control?

A STAR (Standard Terminal Arrival Route) chart specifically helps air traffic control by expediting ATC arrival procedures. It provides a structured and predefined route for aircraft to follow when approaching an airport, which enhances the efficiency of the arrival process. By using STAR charts, controllers can manage the flow of traffic more smoothly, reduce the complexity of arrivals, and minimize conflicts between aircraft. This organized approach also aids in maintaining safety and ensures that aircraft can be sequenced properly for landing, leading to a reduction in workload for both pilots and controllers during busy operational times.

While fuel management, flight altitude adjustments, and safety zone definitions are important considerations in air traffic management, they are not the primary function of a STAR chart, which is focused on facilitating arrivals in an orderly and efficient manner.
