How does the Coefficient of Lift change with an increase in Angle of Attack, up to a certain point?

The Coefficient of Lift increases with an increase in Angle of Attack up to a specific limiting value. As the Angle of Attack (AoA) increases, the airflow over the wing becomes more favorable for generating lift, causing a higher pressure difference between the upper and lower surfaces of the wing. This results in an increase in lift as the angle of attack allows the wing to more effectively deflect airflow downwards, which in turn generates an upward reaction force according to Bernoulli's principle and Newton's third law.

However, it's important to note that this increase in lift will only continue up to a critical angle of attack. Beyond this point, flow separation occurs, leading to a stall, and the Coefficient of Lift will decrease rapidly. Understanding this relationship is crucial for remote pilots, as operating at or near the stall angle can lead to a sudden loss of lift and compromised control of the aircraft. Thus, the correct answer highlights a fundamental concept in aerodynamics that informs safe flying practices.
