The function of ground control is primarily to manage aircraft on the runway and taxiways. Ground control is responsible for ensuring safe and efficient movement of aircraft on the ground, which includes directing them to and from the runway and taxiways. This encompasses coordinating the movement of aircraft to prevent collisions, managing ground traffic, and facilitating smooth transitions from the ramp (the area where aircraft park) to the runway for takeoff, as well as from the runway to the gate after landing.

The other options refer to responsibilities not associated with ground control. Guiding aircraft during takeoff falls under the purview of tower controllers, who manage aircraft as they start their flight, while handling in-flight communications is the role of air traffic controllers in the en-route environment. Monitoring weather conditions is also not part of ground control's duties; that responsibility typically resides within meteorology or flight operations departments to ensure safe flight conditions.
