In air traffic control, what is indicated by the centerline of a taxiway?

The centerline of a taxiway is primarily designed to provide guidance for aircraft as they taxi to and from runways and other areas of the airport. It helps pilots maintain a proper alignment while navigating the taxiway, ensuring safe movement on the ground. By following the centerline, pilots can manage their position accurately, avoiding potential collisions and ensuring compliance with the established taxi routes.

Understanding the taxiway layout is crucial for pilots since accurate taxiing is essential for maintaining safety during ground operations. The centerline marking aids in visual navigation, especially in low visibility conditions or during complex taxi routes. Therefore, it is clear that the purpose of the centerline is to guide aircraft during taxiing, making choice C the most accurate response.
