Which is a direct consequence of increasing angle of attack on a typical wing?

• A. Lift increases and stall approaches
• B. Lift decreases
• C. Drag decreases
• D. Airspeed increases

Answer: (A)

As you raise the angle of attack, the wing deflects more air and creates a larger pressure difference between the upper and lower surfaces, so the lift coefficient increases and overall lift rises up to a point. As you continue to increase the angle, the airflow can no longer follow the wing smoothly and starts to separate, leading toward stall. That combination—lift increasing with angle until the critical point, then stall approaching—is the direct consequence of increasing angle of attack on a typical wing.
