Local control must coordinate with Ground control before using a runway not previously designated as active.

• A. Taxiway
• B. Runway
• C. Helipad
• D. Ramp

Answer: (B)

Coordination between local control and Ground control happens whenever the runway in use changes. The runway that is active is the one designated for takeoffs and landings, and shifting to a runway that wasn’t previously active requires clear communication so both air and ground traffic are aware and can proceed safely. Local control handles the active runway and the surrounding airspace, while Ground control manages movement on taxiways and ramps. If a new runway is going to become active, Ground must be informed to ensure there are no conflicts with ground vehicles or other movements, and to issue appropriate clearances.

The other areas aren’t about which runway is in use. A taxiway, helipad, or ramp is part of ground movement and routing, but they don’t define the active runway for departures and arrivals, so they aren’t the focus of this coordination.
