This issue aside, there is another reason why pilots, aircraft engineers, and designers all talk about ‘chord lines’. However, the diverse nature of their shape and behavior makes referring to a given point on ‘wings’ very difficult. There are many styles of the wing, including: – If you have ever seen more than one aircraft type, you will have noticed that their wings are all different. Why can’t we just refer to the wing “as is” without making imaginary lines? It is an imaginary, superimposed straight line that runs through the wing in cross-section, from the trailing edge to the wing’s leading edge. It is used as a reference point for several different aerodynamic and geometric calculations. In general, the chord line is used as an easy-to-understand reference when referring to the properties of a wing or airfoil. Here’s everything that you need to know… What is the Chord Line in Aviation? The chord line is actually really important, especially when discussing aerodynamics. The chord line is formed by drawing an imaginary straight line from the wing’s trailing edge in cross-section through to the center of the leading edge. The chord line is a datum point on an airplane wing, used to accurately denote the angle of attack in relation to the airflow. What is a chord line? Today we will explain where you’ll find the chord line on an airplane wing and why it is so important. Such as? The chord line is a great place to start, as all wings have one. However, all wings have a few common features. You are probably already aware that airplane wings come in various shapes and sizes.
