What does the red line painted vertically near the nose of the aircraft indicate?

The red line painted vertically near the nose of the aircraft indicates the maximum turning radius of the nose gear. This marking serves as a critical visual cue for ground crew and pilots, ensuring that during taxiing and maneuvering on the ground, the aircraft does not exceed its operational limits regarding the turning radius. By adhering to this guideline, the crew can prevent potential damage to the aircraft's structure, as well as avoid obstacles in the surrounding areas.

Recognizing this line is essential for safe ground handling and aids in maintaining the proper distance from other aircraft, vehicles, and infrastructures on the airfield. Understanding these operational limits enhances safety and efficiency during ground operations.
