Before the critical angle, what usually happens when angle of attack increases?

The wing produces more lift.

  1. Lift becomes zero
  2. Only thrust increases
  3. Lift increases ✔

Why: A larger angle makes the wing turn more airflow downward, increasing lift before the wing reaches its critical angle. Past that limit, airflow can separate and the wing stalls.

Huh, didn't know that: Angle of attack is measured between the wing's chord line and the relative wind.

The dad joke
The wing studied angles because it wanted to rise in geometry.

    Thus, it can be stated that an increase in the angle of attack causes a substantial increase in the amount of lift created.
