Who issues taxi instructions on taxiways at most airports?

• A. Ground controller.
• B. Tower controller.
• C. Approach controller.
• D. Center controller.

Answer: (A)

The main idea here is who coordinates movement on the airport surface. Taxi instructions on taxiways are handled by the Ground Control unit. Ground controllers manage all aircraft and vehicle movements on the airport surface outside of the active runways, routing planes between gates, ramps, and runways, and ensuring safe separation as they taxi. They issue the step-by-step taxi instructions pilots follow, such as which taxiways to use and where to turn, so each aircraft can reach its assigned runway or gate without conflicts. The tower, by contrast, focuses on operations related to the runways themselves and the immediate airspace around the airport—giving takeoff and landing clearances and managing aircraft that are about to enter or leave the runways. Approach and Center control handle arrivals and departures in the terminal area or en route, not the on-ground taxiing patterns. So for typical taxiing on the airport surface, ground control is the best fit.
