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 safety requirements applicable to fixed-wing aircraft in the transport category, and also to many military aircraft, are relatively demanding in the area of pre-stall handling qualities and stall recovery. Some of these aircraft are unable to comply with these safety requirements relying solely on the natural aerodynamic qualities of the ...
The BAC-111 cockpit includes a stick shaker/pusher following its 1963 crash. 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.
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]
Anti-stall (aeroplane controls), a flight envelope protection system designed to prevent an aircraft for stalling, for example by pushing the nose down; Anti-stall strakes, leading-edge slots or extensions, and stall strips; in fluid and aerodynamics, extensions that generates a vortex on a wing surface to postpone aerodynamic stall
The incident was found to have happened after their EV-97 EuroStar light aircraft experienced an aerodynamic stall after descending too steeply.
The testing, which was conducted by FAA flight test engineers and flight test pilots, included aerodynamic stall situations and recovery procedures." [21] After a series of delays, the updated MCAS software was released to the FAA in May 2019. [22] [23] On May 16, Boeing announced that the completed software update was awaiting approval from ...
This happens when the wing exceeds its critical angle of attack. Greene realized that the accident could have been avoided if the pilot had been warned of an imminent stall. Aerodynamic stalls caused the majority of aviation deaths at the time. [2] In the mid-1940s, Greene developed the first practical way to warn the pilot of the aerodynamic ...
