Angle of attack and stalls
- [Instructor] The angle of attack is the acute angle between the relative wind and the chord line of the wing. A stall is an aerodynamic condition in which an aircraft exceeds its given critical angle of attack and is no longer able to produce the required lift for normal flight. In piloting, a stall is only defined as the aerodynamic loss of lift that occurs when the airfoil, which is the wing, exceeds its critical angle of attack. Stalls depend only on the angle of attack, not airspeed. However, the slower an airplane goes, the more angle of attack it needs to produce lift equal to the aircraft's weight. As the speed decreases further, at some point this angle will be equal to the critical angle of attack and the aircraft will stall. An increase in load factor will cause an aircraft to stall at a higher airspeed.
