Turbulence. Upward vertical gusts abruptly increase the angle of attack beyond the stalling angle, irrespective of airspeed. Turns. During a turn in level flight, greater lift is required to offset increased load factor; the critical angle of attack is therefore reached at higher airspeeds. Leading-edge slat - Wikipedia Leading–edge slat. Slats are aerodynamic surfaces on the leading edge of the wings of fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a result of angle of attack and speed, so by deploying slats an aircraft can fly at slower speeds,... Energizing Performance: Leading Edge Slots | Boldmethod
And to generate lots of lift at a slow speed, you'll need a high angle of attack. However, most general aviation aircraft stall at an angle of attack around 15 degrees. Slots delay the stall by increasing the stalling angle of attack (called the critical angle of attack), often past 22 degrees. The Method - Moving Energy From The Bottom To The Top
Angle of attack must not be confused with an airplane's attitude in relation to the ... coordinated with power changes, and auxiliary devices such as flaps, slots, slats, ... When the angle of attack increases to approximately 18 to 20 degrees (on ... This is the stalling or critical angle of attack, and is often called the burble point.

Numerical Simulation of Flow Past NACA 0012 Airfoil Using a Co-Flow ... Figure 41: Stall angle analysis when injection slot is at 5% chord length ..... attack, jet momentum coefficient, injection angle and injection slot location ...... thin airfoil and thus the increase in stall angle of tangential CFJ control is not significant. Leading-edge slot - Wikipedia At an angle of attack above about 15° many airfoils enter the stall. Modification of such an airfoil with a fixed leading-edge slot can increase the stalling angle to between 22° and 25°. Slots were first developed by Handley Page in 1919 and the first aircraft to fly
At an angle of attack above about 15° many airfoils enter the stall. Modification of such an airfoil with a fixed leading edge slot can increase the stalling angle to between 22° and 25°.
Flaps increase the drag coefficient of an aircraft due to higher induced drag caused by the distorted spanwise lift distribution on the wing with flaps extended.
Angle of attack must not be confused with an airplane's attitude in relation to the earth's surface, or with angle of incidence (the angle at which the wing is attached relative to the longitudinal axis of the airplane). Angle of attack is most frequently defined as the angle between the chord line of the wing, and the relative wind.
However, up to a point, lift coefficient reaches maximum and drops significantly. The angle of attack in which the lift coefficient reaches maximum is the critical angle (in the graph above, they use the notation stall angle of attack instead, but it means the same thing).
