Instruct civil aircraft, military transport, and cargo types to contact departure control about ___ mile(s) beyond the runway end.

• A. one-half mile
• B. one mile
• C. two miles
• D. three-quarters mile

Answer: (A)

Switching from the tower to departure control happens at a defined point beyond the runway end to ensure you’re in controlled airspace with a timely handoff. For civil aircraft, military transport, and cargo types, that point is one-half mile beyond the runway end. This distance gives the departure controller reliable radar contact early enough to issue an initial heading and altitude, while you’re still close to the runway environment so you can establish a safe climb. It standardizes the handoff, helping traffic flow stay orderly and reducing the chance of miscommunication or delay. Other distances would place you too close to the runway or too far away for a prompt, coordinated start to your en-route separation.
