Which position is primarily focused on the handling of aircraft movements on the runways?

The position primarily focused on the handling of aircraft movements on the runways is Tower Control. This role is crucial for ensuring the safe and efficient operation of aircraft during their takeoffs and landings, as well as while they are on approach to or departing from the runway.

Tower Control personnel are responsible for directing aircraft on the runway, including granting takeoff and landing clearances. They coordinate with other positions to ensure that the flow of traffic remains orderly and safe, managing the interactions between arriving and departing flights. The focus of Tower Control is specifically on the airspace in the immediate vicinity of the airport, making it essential for runway management.

In contrast, Ground Control deals with aircraft movement on the taxiways and in the areas surrounding the runway, while Apron Control is responsible for managing aircraft on the parking areas and gates. Clearance Delivery focuses on preparing aircraft for departure by providing the necessary clearances before they taxi. Each of these roles plays an important part in overall aircraft operations, but Tower Control is directly responsible for the runway management.
