What part of a wing is referred to as the leading edge?

The leading edge of a wing is defined as the front part of the wing or airfoil. This area is crucial in aerodynamics, as it is the first part of the wing that meets the oncoming airflow. The design and shape of the leading edge significantly affect the overall performance of the wing, including lift generation and airflow separation. It is engineered to manage the airflow smoothly over the surface of the wing, which enhances the aircraft's performance. The leading edge also plays a vital role in stall characteristics, as its shape can influence the angle of attack at which the wing will begin to lose lift. Understanding the function and importance of the leading edge aids in comprehending wing performance, control, and overall aircraft design.
