What is referred to by the term "cordline" in relation to aircraft wings?

The term "cordline" refers specifically to the straight line that connects the leading edge and the trailing edge of an aircraft wing. This line is crucial for understanding the wing's aerodynamic characteristics, as it represents the chord of the wing, providing a reference from which other measurements, such as camber and angle of incidence, can be defined. The concept of cordline is fundamental in aerodynamics, as it helps determine how air flows over the wing, affecting lift and drag performance.

In aviation, understanding the geometry of the wing, including the cordline, is essential for effective aircraft design and analysis. It also plays a role in determining the wing's efficiency and performance during various phases of flight.
