In generic terms, a stick pusher is known as a stall identification device or stall identification system. [73] A stick shaker is a mechanical device that shakes the pilot's controls to warn of the onset of stall. A stall warning is an electronic or mechanical device that sounds an audible warning as the stall speed is approached. The majority ...
The falling leaf is often used as a training maneuver, teaching the pilot to control the plane during a stall and helping beginners to overcome the fear that happens when a plane stalls unexpectedly. It is generally performed from a low-speed, straight, level stall, to avoid the buffeting, departure from the normal flightpath, and flat spin ...
A stick shaker is a mechanical device designed to rapidly and noisily vibrate the control yoke (the "stick") of an aircraft, warning the flight crew that an imminent aerodynamic stall has been detected. It is typically present on the majority of large civil jet aircraft, as well as most large military planes.
The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed, when contaminated with ice because of the significantly lowered lift coefficient and increased aerodynamic drag. [6] Even small amounts of ice will have an effect, and if the ice is rough, it can be a large effect nonetheless.
The effect of airfoil geometry on dynamic stall is quite intricate. As is shown in the figure, for a cambered airfoil, the lift stall is delayed and the maximum nose-down pitch moment is significantly reduced. On the other hand, the inception of stall is more abrupt for a sharp leading-edge airfoil. [8] More information is available here. [13]

Aerodynamic spin diagram: lift and drag coefficients vs. angle of attack. Many types of airplanes spin only if the pilot simultaneously yaws and stalls the airplane (intentionally or unintentionally). [5] Under these circumstances, one wing stalls, or stalls more deeply than the other.
Just after winning a gold medal in the individual vault final in Paris on Aug. 3, Biles spoke during a press conference about the future of her signature vault. "This is my last, definitely ...
