What does the term 'angle of attack' refer to?

The term 'angle of attack' specifically refers to the angle between the chord line of the wing and the oncoming airflow. This angle is a critical parameter in aerodynamics as it affects the lift generated by the wing. When the angle of attack increases, the amount of lift produced also typically increases, up to a certain point. Beyond this point, if the angle of attack becomes too steep, the wing may stall, resulting in a loss of lift.

Understanding this concept is essential for pilots and engineers, as managing the angle of attack can significantly influence aircraft performance during different phases of flight, such as takeoff, cruising, and landing. The importance of angle of attack is central to achieving safe and efficient flight operations.
