What is the main responsibility of ground controllers at an airport?

The main responsibility of ground controllers at an airport is to coordinate ground traffic on taxiways and runways. This role is crucial for ensuring the safety and efficiency of aircraft movements while they are on the ground. Ground controllers direct the movement of aircraft that are taxiing to and from runways, managing not only the order of departures and arrivals but also the interactions between taxiing planes, vehicles, and equipment on the airfield.

This coordination includes providing clearances for aircraft to taxi and ensuring that the movement of all ground vehicles is appropriately managed to avoid any potential collisions. By maintaining an organized flow of traffic, ground controllers help prevent accidents and delays, contributing significantly to overall airport operations.

In contrast, the other responsibilities outlined in the incorrect choices involve tasks that fall outside the primary duties of ground controllers. Monitoring in-flight emergencies pertains to air traffic controllers, while conducting weather assessments is typically the responsibility of meteorological services. Overseeing aircraft service stations pertains to ground handling or ramp agents, who focus on servicing the aircraft rather than managing air traffic on the ground.
