Approach Control is a service provided by air traffic control that manages the arrival of aircraft into an airport. It ensures that planes are safely guided during their descent and approach phases, maintaining safe distances between them. This service is crucial for preventing collisions and managing air traffic efficiently, especially in busy airspace. The primary goal of Approach Control is to provide instructions to pilots regarding altitude, speed, and flight path. By coordinating with Air Traffic Control and using radar technology, approach controllers help ensure that aircraft land safely and on time, contributing to overall flight safety and efficiency.
