What is the primary function of Aircraft Taxi Lines?

The primary function of Aircraft Taxi Lines is to keep the nose wheel centered on the taxiway. These lines are specifically designed to aid pilots and ground vehicle operators in navigating safely and efficiently along taxiways. By following these painted lines, ground operators can maintain proper alignment, ensuring that aircraft do not veer off the designated path. This is crucial for preventing accidents and ensuring safe movement in the congested airside environment of an airport.

While other options suggest various purposes for taxi lines, such as parking guidance, indicating speed limits, or marking fuel service areas, their primary design and function focus on centerline guidance. Thus, taxi lines are fundamentally about supporting the safe and orderly movement of aircraft on the ground, emphasizing the importance of alignment for operational safety.
