Ground Control must obtain approval from ______ before authorizing an aircraft or vehicle to cross or use any portion of an active runway.

• A. Local Control
• B. Flight Control
• C. Ground Operations
• D. The Tower Supervisor

Answer: (A)

Ground Control must obtain approval from Local Control before authorizing an aircraft or vehicle to cross or use any portion of an active runway because Local Control is responsible for managing the active runways and their associated traffic. This includes coordinating takeoffs, landings, and any ground movements that may affect the safety and flow of operations on the runway. The hierarchical structure of air traffic control ensures that Ground Control must communicate with Local Control to ensure safety and prevent potential conflicts between aircraft in the air and those on the ground. By obtaining this approval, Ground Control can confirm that it is safe for other traffic to cross the runway without compromising safety protocols.
