What is the primary function of the Airport Traffic Control Tower (ATCT)?

The primary function of the Airport Traffic Control Tower (ATCT) is to provide air traffic control services to aircraft. This critical role involves ensuring that aircraft take off, land, and taxi safely on the airfield. Air traffic controllers coordinate the movement of aircraft in the vicinity of the airport, managing both the arriving and departing flights to prevent collisions and maintain an efficient flow of air traffic. They communicate with pilots, issuing instructions relating to takeoff and landing clearances, as well as providing information about weather conditions and runway usage.

While managing passenger check-in, baggage handling, and airport maintenance are essential operations within an airport, they do not fall under the purview of the ATCT. Instead, these activities are typically handled by ground services and airline staff. The exclusive focus of the ATCT on aircraft operations underscores its vital importance in maintaining safety and efficiency in the aviation environment.
