Aerodynamics associated with stalls in various airplane configurations, including the relationship between angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects.
Bottom line
It is possible to stall the wing at any airspeed, at any flight attitude, and at any power setting. For a given configuration, the airplane always stalls at the same angle of attack, referred to as the critical angle of attack.
Key numbers
| Number | What it means |
|---|---|
| 16°–20° depending on airplane design | Critical AOA |
| 2.0 load factor in a level altitude 60° banked turn | 60° bank load |
| 41% above 1G stall speed in a coordinated, level 60° banked turn at 2G | Stall speed rise |
| 1.41 load factor in a level altitude 45° banked turn | 45° bank load |
