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 system is composed of fuselage or wing-mounted angle of attack (AOA) sensors that are connected to an avionics computer, which receives inputs from the AOA sensors along with a variety of other flight systems. When this data indicates an imminent stall condition, the computer actuates both the stick shaker and an auditory alert. [8]
A system for this purpose is known as a stick pusher. 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 ...
WASHINGTON/PARIS (Reuters) - An anti-stall system at the center of a probe into the crash of a Boeing 737 MAX jetliner in Indonesia five months ago was also at play when an identical aircraft ...
SEATTLE/LONDON (Reuters) - A Boeing Co software fix for the grounded 737 MAX will prevent repeated operation of an anti-stall system at the centre of safety concerns and deactivate it altogether ...
In the 1960s, a basic pitch control system known as the stick shaker was installed in the Boeing 707 to avoid stalling. [6] Later, a similar system to avoid stalling, in this case specifically called the Maneuvering Characteristics Augmentation System (MCAS), was implemented on the Boeing KC-46 Pegasus military aerial refueling tanker.

A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight ...
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 ...
