Which of the following is Not a duty of the Clearance Delivery position?

• A. Ensuring separation of aircraft
• B. Issuing departure clearances
• C. Coordinating with air traffic controllers
• D. Providing initial contact with pilots

Answer: (A)

Clearance Delivery is responsible for preparing and issuing the initial departure clearance and providing the first contact with pilots before takeoff. They convey the flight’s route, altitude, and any special instructions, and they verify the pilot’s readback. They also coordinate with other controllers to ensure the clearance matches the flight plan and to hand off information as the aircraft moves toward the next control position. The responsibility for keeping aircraft safely separated falls to the air traffic control system—tower, approach, and en route controllers—who sequence and separate traffic within their respective airspaces. So, the duty that doesn’t belong to Clearance Delivery is ensuring separation of aircraft.
