What is the role of the control tower at an airport?

The control tower plays a critical role in managing air traffic at an airport. Its primary responsibilities include the safe spacing and sequencing of aircraft during takeoff and landing, as well as coordinating the movement of aircraft on the ground, including taxiing. Air traffic controllers in the tower use radar, visual observation, and communication with pilots to maintain a safe and efficient flow of air traffic. This ensures that aircraft can safely enter and exit the airport environment while avoiding potential collisions and minimizing delays.

This function is essential because the airport environment can become complex, especially during peak hours. By overseeing and directing air traffic operations, the control tower organizes the various components of flight operations, thereby allowing for a structured and safe airspace. Other options mention roles that do not fall under the direct responsibilities of a control tower, reinforcing why managing air traffic and ensuring the safe landing and takeoff of aircraft is the sole focus of this integral part of airport operations.
