What is the role of air traffic control (ATC) in UAS operations?

The role of air traffic control (ATC) in UAS operations primarily involves the authorization of UAS operations in controlled airspace. When a UAS pilot intends to operate in areas where ATC has jurisdiction, they must communicate with ATC to receive the necessary clearances and instructions to ensure the safe and efficient use of airspace. This is crucial because UAS can operate at various altitudes and can be integrated into air traffic alongside manned aircraft.

ATC monitors the airspace and provides guidance, which helps prevent collisions and maintains safety, especially in busy air traffic zones. The authorization process is directly tied to the responsibilities of ATC to manage and segregate air traffic, ensuring that UAS operations do not interfere with other aircraft or create hazardous situations.

While ATC does provide important safety and operational guidance, their primary function concerning UAS is tied to the authorization process in controlled airspace, making this the most relevant choice among the options provided.
