inverted spin

inverted spin

A condition in which an aircraft is in a spin but inverted. Relative to the pilot, the motion is compounded in the nose-down sense; a rolling velocity spins in one direction while yawing spins in the opposite. Unlike in a normal spin, the pilot can feel the pressure exerted against the seat belt by negative g. Most aircraft revert to a normal spin from an inverted spin on their own. Recovery action for each aircraft is given in the flight manual of the aircraft.
