What is the primary function of Air Traffic Services (ATS) in relation to airfield operations?

The primary function of Air Traffic Services (ATS) in relation to airfield operations is to control airspace necessary to support those operations. ATS plays a crucial role in ensuring the safe and efficient movement of aircraft within designated airspace, which encompasses takeoffs and landings at airfields. This involves providing air traffic control services, including directing aircraft during all phases of flight to prevent collisions, manage traffic flow, and coordinate operations between different aircraft and ground services. The effective management of airspace ensures that aircraft can operate safely, allowing for the coordination of arrivals and departures, as well as handling any potential conflicts.

The other options, while relevant to certain aspects of airport operations, do not align with the primary responsibilities of ATS. Managing in-flight entertainment, providing maintenance for aircraft, and assisting with baggage handling are functions that fall outside the scope of air traffic services. These tasks are typically handled by different departments and personnel focused on customer service and aircraft maintenance rather than airspace management.
