Definition#
The critical angle of attack (also called the stalling angle) is the angle of attack at which an airfoil produces its maximum lift coefficient. Beyond this angle, the airflow separates from the upper surface and the wing stalls.
Why It Matters Operationally#
For most airfoils, the critical angle is between 15° and 20°. A stall can occur at any airspeed and any pitch attitude if this angle is exceeded.
