Tailspin - Phases

Phases

In aircraft that are capable of recovering from a spin, the spin has four phases. For all or some types of spin some airplanes are not recoverable. At low height recovery may also be impossible. In both cases, only the first three phases occur.

  • Entry – The pilot stalls the plane while in uncoordinated flight.
  • Incipient – With one wing more stalled than the other, the rotation starts.
  • Developed – The aircraft's rotation rate, airspeed, and vertical speed are stabilized. At least one wing of the aircraft is stalled.
  • Recovery – After appropriate control inputs, the angle of attack of both wings decreases below the critical angle of attack, rotation slows. The nose attitude of the aircraft steepens, airspeed increases, autorotation stops, the aircraft is no longer stalled. The controls respond conventionally and the airplane can be returned to normal flight.

Famous quotes containing the word phases:

    That man is to be pitied who cannot enjoy social intercourse without eating and drinking. The lowest orders, it is true, cannot imagine a cheerful assembly without the attractions of the table, and this reflection alone should induce all who aim at intellectual culture to endeavor to avoid placing the choicest phases of social life on such a basis.
    Mrs. H. O. Ward (1824–1899)

    This socialism will develop in all its phases until it reaches its own extremes and absurdities. Then once again a cry of denial will break from the titanic chest of the revolutionary minority and again a mortal struggle will begin, in which socialism will play the role of contemporary conservatism and will be overwhelmed in the subsequent revolution, as yet unknown to us.
    Alexander Herzen (1812–1870)

    But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps it’s a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.
    Saf Lerman (20th century)
