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.
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 pilot applies full aileron, then rudder in the opposite direction and full down elevator. The plane will "snap" and then the pilot must neutralize aileron (and in some cases apply aileron in the same direction as the rudder) and the plane will be in an inverted flat spin. Pop-Top Same as a blender, but going up. The pilot must have a good ...
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. [1] [2] The term is somewhat loosely applied, and can also refer to other measurements such as maneuverability.
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.
Rotor map of dynamic stall locations for all conditions. Stage 4: full separation of the flow on the upper surface of the airfoil can be observed, accompanied by the peak of nose-down pitch moment. Stage 5: the full flow reattachment is achieved as the AoA gradually decreases until it is fairly smaller than the static stall angle. [10]
High school football enthusiasts who want to place a bet on a big game have no choice but to turn to an offshore site. Accepting a wager on high school sports is outlawed in Nevada and other U.S ...
In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. [3] Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift.
