What is the primary function of a control tower at an airport?

The primary function of a control tower at an airport is to control runway operations. This includes managing the safe and efficient movement of aircraft on the ground and in the airspace around the airport. Control towers are staffed by air traffic controllers who communicate with pilots to provide them with instructions, clearances, and updates regarding weather and traffic conditions.

This role is crucial for ensuring that takeoffs and landings are safely coordinated, preventing accidents and facilitating smooth operations. The control tower’s responsibility encompasses managing aircraft arrivals and departures, sequencing traffic, and ensuring that safety protocols are followed, particularly in busy airport environments.

Other functions listed, such as managing aircraft maintenance, providing passenger services, or offering food and retail services, are handled by different departments within the airport and do not fall under the primary operational focus of a control tower. Thus, the primary duty of controlling runway operations is essential for the overall safety and efficiency of airport operations.
