Angle of Attack

Lesson 5

While we are at it, another caveat to remember is that different parts of the wing stall at different times. For example, the wing root in a single engine propeller aircraft will have a lower AOA than the wing tips due to the slipstream tube from the propeller wash. All aircraft stall at a specified AOA and not a specific airspeed. Military jets with thin airfoil have a higher AOA (20-21 degrees) while the thicker wings will have the critical AOA at 15-18 degrees.
