Asunto:  Survival Spins

Spinning brings ideas of exhilaration and adventure, but it is different in the case of aircraft because getting a plane into a spin is one of the most dangerous things that a pilot can do while flying.

A spin is a situation in which a plane is found when two conditions are met: first, the wings of the aircraft must stall, and second, they must do so asymmetrically.

Stalling a wing means to put it into a condition in which it produces no more lift, usually due to a lack of enough speed to produce the aerodynamic forces that in turn, induce lift. If you put the nose of an aircraft up enough, it will sooner or later produce a wing stall.

And for a stall to become asymmetric, that means that one wing must fall into such a no-lift condition before the other. This induces a rotation, so added to gravity, this produces a corkscrew fall from the ski.

Recovering an airplane from a spin is theoretically simple, but the risk is that while doing so you will run out of enough height and crash into the ground, and in such case, there is no chance of survival.

This is why many air crashes near airports occur, and why they are almost always fatal, because with the low speeds usually associated with departures and arrivals around airports, just one mistake is enough to send any aircraft into a spin: the pilot need only to fail to coordinate commands; if you just move the ailerons into one direction, and the rudder into the opposite one, your plane will spin and fall.

However, spins were used many times in dogfights, in order to escape pursuing airplanes when there was no other way around. During WWI, many biplanes and their pilots owed their survival to their own lucky spins.
