What do wing station numbers measure from?

Wing station numbers are a system used to locate points or features along the length of an aircraft's wing, specifically measured from the centerline of the aircraft. This system aids in the design, maintenance, and structural analysis of wings. By using the centerline as a reference point, engineers can consistently identify and communicate the position of various components or measurements across different aircraft and designs.

This central reference is crucial because it provides a standardized method for identifying locations on the wings, thereby ensuring clarity and precision in discussions about wing structure, performance, and maintenance procedures. Using the centerline allows for uniformity regardless of the specific design or dimensions of an aircraft, which may vary significantly between models.

Understanding this reference point helps in various applications including load calculations, aerodynamic assessments, and repair strategies, maintaining a clear focus on the structural integrity and performance of the wing relative to the entire aircraft body.
