In the CMA escort example, who coordinates crossing Runway 21R?

• A. Ground Control
• B. Nellis Tower
• C. Airfield Operations
• D. Security

Answer: (B)

Crossing an active runway is controlled by the air traffic control facility that has authority over the runway, which at Nellis is Nellis Tower. The tower monitors all traffic on and across Runway 21R and issues the actual crossing clearance when it’s safe, coordinating as needed with ground controllers to ensure the escort moves without conflicting with arriving or departing aircraft. Ground Control handles taxi routes on the surface, but the permission to cross a runway comes from the tower. Airfield Operations and Security support safety and procedures, but they don’t issue the real-time runway crossing clearance.
