Spin (flight) Guide, Meaning , Facts, Information and Description
In flying, a spin is a special case of stall. In this state, an aircraft is not flying, but falling - the wing is not generating sufficient lift to support the aircraft as with a normal stall; however, in a spin, the aircraft is rotating about its vertical axis.A spin may occur when a stall occurs that affects one wing more than the other. This many happen during an uncoordinated turn or other manoeuver. An aircraft may be deliberately spun for purposes of training, test flying, and aerobatics. A spin is usually entered by flying the aircraft into a stall condition. As the stall point is reached, the rudder is used to yaw the aircraft. The outward wing will keep flying, the inner wing will stall and the aircraft will enter the spin. Some aircraft are naturally stable and the controls will need to be held until the spin is fully developed.
A spin in which the aircraft is still essentially the right way up (though falling in a nose-down attitude) is called a normal or upright spin, one in which it is upside-down is called an inverted spin.
Spinning is often feared by pilots, especially novices, and spin recovery is no longer a compulsory part of the Private Pilot License syllabus. However, it makes good sense for every pilot to know how to get out of a spin should it occur. Practice makes this much easier, because the sensation of spinning is generally unpleasant and disorienting.
A spin is a form of stall, a fact that eluded many pioneer aviators until spin recovery was discovered sometime in the 1910s. The key is to get the wings flying again. However, the spin rotation should first be arrested so that both wings can contribute fully to the recovery. The pilot should detect the spin direction and apply opposite rudder until the rotation stops. At this point the control column should be moved forward to reduce the angle of attack. As the aircraft pitches down, the wing will regain flow and start to generate lift. At this point the aircraft will be in a dive. The pilot must then ease out of the dive taking care not to exceed the g-stress rating of the aircraft. Pulling up too sharply can result in structural damage or another stall. Naturally, spin recovery can require a considerable height.
Note: This is only a general spin recovery technique. Use only the manufacturer's recommended procedures. Spins should not be taken lightly. Statistics show that most accidents involving newly licensed commercial pilots are low altitude stall-spin accidents. This is an Article on Spin (flight).
