When tasks are split among Aerodrome controllers, what are the two main roles?

When tasks are divided among Aerodrome controllers, the two principal roles recognized in the air traffic management system are 'Air' controllers and 'Ground' controllers. The 'Air' controllers are responsible for the safe and efficient handling of aircraft movement within controlled airspace, typically during takeoff and landing phases, as well as during the flight in the airspace surrounding an airport. These controllers focus on managing the aircraft that are airborne.

On the other hand, 'Ground' controllers handle all activities on the airport's ground, specifically for aircraft movement on taxiways and runways when they are not airborne. They coordinate the movements of aircraft on the ground to ensure safe transitions between the runway and the taxiway, including managing the traffic flow at the airport and ensuring that aircraft can move safely to and from the gates.

This clear division of responsibilities allows for a more organized and efficient operation at airports, ensuring safety and minimizing the risk of errors that could arise from having overlapping roles.
