Wing twist is an aerodynamic feature added to aircraft wings to adjust lift distribution along the wing.. Often, the purpose of lift redistribution is to ensure that the wing tip is the last part of the wing surface to stall, for example when executing a roll or steep climb; it involves twisting the wingtip a small amount downwards in relation to the rest of the wing.
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 ...
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. Its purpose is to tailor the spanwise lift distribution or reduce the probability of wing tip stall. Winglets have the opposite effect to washout.
In Canada, spins are a mandatory exercise to get the private and commercial pilot licenses; Canadian recreational pilot permit candidates (1 level below private pilot license) must do a stall and wing drop (the very beginning of the entry to a spin) and must recover from a stall and wing drop as part of training.

divergence where the aerodynamic forces increase the twist of a wing which further increases forces; control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases reverses, the control effectiveness; and; flutter which is uncontained vibration that can lead to the destruction of an aircraft.
If your goal is to improve general muscular fitness, you should aim to perform 1-4 sets of 8-15 repetitions per exercise, he says. You can adjust the ball weight you're using for each exercise, as ...
A gyroscopic exercise tool is a specialized device used in physical therapy to improve wrist strength and promote the development of palm, wrist, forearm, and finger muscles. It can also be used as a unique demonstration of some aspects of rotational dynamics .
A leading-edge slat is an aerodynamic surface running spanwise just ahead of the wing leading edge. It creates a leading edge slot between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high angles of attack. This delays the stall, allowing the aircraft to fly at a higher angle of ...
