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 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]
On aircraft with swept wings, wing tip stall also produces an undesirable nose-up pitching moment which hampers recovery from the stall. Washout may be accomplished by other means e.g. modified aerofoil section, vortex generators, leading edge wing fences, notches, or stall strips. This is referred to as aerodynamic washout.
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.
A wider consequence of the incident was a new design requirement related to the pilot's ability to identify and overcome stall conditions; the design of a Transport category aircraft that fails to comply with the specifics of this requirement may be acceptable if the aircraft is equipped with a stick pusher.

The incident was found to have happened after their EV-97 EuroStar light aircraft experienced an aerodynamic stall after descending too steeply.
A spiral dive is not a spin; it starts, not with a stall or from torque, but with a random perturbation, increasing roll and airspeed. Without prompt intervention by the pilot this can lead to structural failure of the airframe, either as a result of excess aerodynamic loading or flight into terrain. The aircraft initially gives little ...
