The angle of attack at which a wing stalls remains constant regardless of which of the following factors?

The angle of attack at which a wing stalls is primarily determined by the wing's design and the characteristics of airflow over it, and it remains constant regardless of several external factors. Among the options presented, the first choice accurately states that this stalling angle does not change with variations in weight, dynamic pressure, bank angle, or pitch attitude.

Weight affects how much lift is required for level flight and can influence the overall performance of the aircraft, but it does not alter the inherent aerodynamic properties of the wing. Similarly, dynamic pressure (which is a function of air density and velocity) influences the lift and drag forces acting on the wing but does not change the fundamental angle of attack at which the airflow can no longer remain attached to the wing surface, leading to a stall. Furthermore, variations in bank angle and pitch attitude can affect the lift and stall speed, but the angle of attack at which stalling occurs remains constant as it is a characteristic of the airfoil itself.

In essence, while various operational factors can influence flight characteristics, the stall angle is a specific property of the wing that does not vary with these conditions. Therefore, the assertion that the angle of attack at which a wing stalls is consistent regardless of these factors is correct.
