With whom must the local controller coordinate before using a runway not previously designated as the active runway?

• A. Ground Control
• B. Tower
• C. Approach Control
• D. Clearance Delivery

Answer: (A)

Coordinating with Ground Control is essential when the active runway changes because Ground Control manages all movement on the airport movement area, including taxiways and runways. Before using a runway that wasn’t previously designated as active, the local controller must alert Ground Control so they can sequence ground traffic, issue or adjust taxi instructions, and ensure the surface is clear of conflicting movements. This prevents runway incursions and keeps both air and ground traffic properly coordinated. Approach Control handles airborne traffic in the terminal area, and Clearance Delivery issues clearances, but neither oversees real-time ground movements on the movement area or the runway status change.
