How is the chord of a wing defined?

The chord of a wing is defined as the straight-line distance from the leading edge to the trailing edge of the wing. This measurement represents the wing's width and plays a crucial role in aerodynamic calculations and performance characteristics. The wing's chord is essential for understanding lift generation and airflow over the wing's surface.

Although the option about the width of the wing at its widest point may initially seem relevant, it does not accurately capture the definition of chord, which specifically refers to the measurement from the leading edge to the trailing edge along the span of the wing. Other options, such as the distance from the tip of the wing to the fuselage or the measurement of the wing's camber, describe different aspects of wing structure and geometry, but they do not pertain to the definition of chord itself. Thus, the accurate understanding of this term is vital for anyone involved in assembly and rigging practices related to aviation.
