an aerobatic maneuver whereby the airplane is flown vertically down towards the ground, while being made to roll. Easy to get into one but not always so easy to get out of, especially when the airplane-to-ground distance has been badly judged. In this instance, you will need to use the plastic bag.
rapid descent of an aircraft in a steep spiral
an aggravated stall in which one wing is more fully stalled than the other and thus experiences less lift and more drag
an aggravated stall that results in autorotation involving a rapid descent in a corksrew path
an aggravated stall where one wing produces more lift than the other, resulting in autorotation
a stall that has continued, with one wing more stalled than the other
a dangerous situation for an aircraft when, after suffering a stall (loss of lift), one wing creates lift while the other is stalled - this causes the aircraft to rapidly spin and if not corrected results in a crash.
Another aerobatic maneuver in which the aircraft is flown vertically towards the ground while rolled. As with all maneuvers - be extra careful.
A phenomenon which occurs when all lift is lost and the aircraft descends like a falling leaf. Control is normally restored by centering all control surfaces.
In aviation, a spin is an aggravated stall resulting in autorotation wherein the aircraft follows a downward corkscrew path. Spins are characterized by high angle of attack, low airspeed, and high rate of descent. Spins are not spiral dives, which are characterized by low angle of attack and high airspeed, and are not a type of stall.
