What is the white guidance line in the "U" also known as?

The white guidance line in the "U" is known as the Wing Tip Clearance Line because it is specifically designed to help drivers maintain the appropriate distance from obstacles, particularly aircraft wings, during taxi operations. This line serves as a visual reference that indicates the safe clearance distance from adjacent structures or parked airplanes, ensuring that the wing tips do not risk collision with other objects or vehicles. Following this line assists drivers in maneuvering safely within restricted areas and enhances overall ground safety at the airport. By adhering to these established lines, drivers contribute to the efficient and secure movement of aircraft and ground vehicles.
