What is the primary function of the ground control tower at O'Hare Airport?

The primary function of the ground control tower at O'Hare Airport is to guide taxiing aircraft. This role involves directing aircraft as they move on the ground, ensuring safe and efficient operations while managing the flow of air traffic in and around the airport's taxiways and ramps. Ground controllers coordinate the movement of airplanes from the ramp to the runway for takeoff, as well as from the runway back to the terminal area after landing. This critical responsibility helps maintain a safe environment and prevents accidents or congestion on the ground.

While managing airborne traffic is vital, that task falls under the responsibilities of the tower controllers, who oversee aircraft in the air. Coordinating runway maintenance is an essential airport operation but does not directly pertain to the immediate control of aircraft during taxi. Monitoring weather conditions is crucial for overall airport safety but is typically handled by a dedicated meteorological team rather than the ground control tower specifically.
