Which line type helps in avoiding obstacles for aircraft wings?

The Aircraft Taxi Line is specifically designed to assist pilots and ground vehicle operators in navigating safely around the airfield, particularly in areas where aircraft movement occurs. It indicates a clear path that ensures adequate clearance from potential ground hazards, including obstacles that could interfere with aircraft wings. By following the Aircraft Taxi Line, vehicles and aircraft can maintain the proper distance from structures, other aircraft, and equipment, thereby minimizing the risk of collisions or damage.

In contrast, while the Centerline and Taxiway Edge lines are important for guiding aircraft along taxiways and maintaining proper spatial orientation, they do not specifically focus on the clearance necessary for the wings. The Parking Boundary Line serves to define the limits of parking areas but does not aid in guiding movement to avoid obstacles. Therefore, the Aircraft Taxi Line is the most relevant option for preventing wing obstruction during aircraft maneuvering.
