- Definição1
- A maneuver in which an airplane descends ina steeply banked, turning flight path. A spiral is sometimes confused with a spin, but the two maneuvers are totally different. In a spin, one wing is stalled and the other is producing lift, while in a spiral, both wing produce lift. The airspeed does not increase as an airplane spins, but in a spiral, the speed can increase to a dangerous level if the spiral is allowed to continue.
