Spin — an aggravated stall and autorotation. In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. [1]
Spin — an aggravated stall and autorotation. For fixed-wing aircraft, autorotation is the tendency of an aircraft in or near a stall to roll spontaneously to the right or left, leading to a spin (a state of continuous autorotation). [1] [2]
A spin is more complex, involving intentionally stalling a single wing, causing the plane to descend spiraling around its yaw axis in a corkscrew motion. A hammerhead (also known as a stall turn ) is performed by pulling the aircraft up until it is pointing straight up (much like the beginning of a loop), but the pilot continues to fly straight ...
Having crossed controls, as in any form of uncoordinated flight, is aerodynamically unsound and if not monitored closely by the pilot can result in a stall or a spin. These stalls, cross-controlled stalls, are emphasized in flight instructor training due to their commonality of resulting in loss of control in flight with insufficient altitude ...
The Aresti Catalog is the Fédération Aéronautique Internationale (FAI) standards document enumerating the aerobatic manoeuvers permitted in aerobatic competition.Designed by Spanish aviator Colonel José Luis Aresti Aguirre (1919–2003), each figure in the catalog is represented by lines, arrows, geometric shapes and numbers representing the precise form of a manoeuver to be flown.
NTSP said the pilot, who was fatally injured, failed to maintain speed when dealing with a stall. Aug. 6, 1983 : During an air show, an aircraft hit the ground before recovering from its spin.
When the mean angle of attack of the wings is beyond the stall a spin, which is an autorotation of a stalled wing, may develop. A spin follows departures in roll, yaw and pitch from balanced flight. For example, a roll is naturally damped with an unstalled wing, but with wings stalled the damping moment is replaced with a propelling moment. [9 ...
Flat spin A spin induced with full up elevator, full rudder, and full aileron. Once the spin is initiated you will level the ailerons and increase engine speed a bit to pull the aircraft around. This will in turn flatten the spin. Inverted Flat spin The same as the above but inverted. Inverted flat spins are easier to control, but can be hard ...
