		Spoilers are used by gliders in particular to control their rate of descent, and thus achieve a controlled landing at a desired spot.
		Spoilers differ from airbrakes in that the latter are designed to increase drag while making little change to lift, spoilers greatly reduce lift while making little change to drag.
		On landing, the deployment of these spoilers causes a dramatic loss of lift and hence the weight of the aircraft is transferred from the wings to the undercarriage, allowing the wheels to be mechanically braked with much less chance of skidding.

	Aerodynamic engineering - Discussion: Spoilers as Lateral Control
		With spoilers, there is just a reduction of lift on one side, which results in a rolling moment and a net decrease in lift.
		Spoilers are different from ailerons in that ailerons generate roll moment that is pretty linear to their deflection; not so with spoilers.
		Spoilers generate very little roll moment if the deflection is small enough to keep the spoiler inside the boundary layer, but as soon as the deflection is big enough to have the spoiler panel protruding out of the boundary layer, a substantial roll moment appears.

		In this report are presented the results of wind-tunnel tests of retractable spoilers on the upper surface of a Clark Y wing, which have been made as part of an investigation of lateral control devices being conducted by the National Advisory Committee for Aeronautics.
		Spoilers with chords up to 15.0 percent of the wing chord were tested in several locations on a plain rectangular wing and in two locations on the same wing equipped with a 20.0 percent chord split flap down 60 degrees.
		Charts are given for four representative angles of attack from which values of rolling- and yawing-moment coefficients may be obtained for spoilers up to 15.0 percent chord located on the upper surface of a Clark Y wing.

		A tool of aeronautics in which a flight simulator on the ground is used to create an environment where a pilot sees, hears and feels like he or she is in a real aircraft.
		Pilots deploy spoilers when they land so that the airplane is no longer " lifted " into the air.
		A motion of an aircraft is said to have stability, or be stable, if the aircraft will return to that motion after a disturbance, without the pilot having to move the controls.

		Aeronautics is the mathematics and mechanics of flying objects, in particular airplanes.
		In steady, level flight, an aircraft can be considered as being acted on by four forces in equilibrium: lift, weight, thrust, and drag.
		As well as ailerons there are sometimes also spoiler s - small hinged plates on the upper surface of the wing, originally used to produce drag to slow the aircraft down.

		The spoiler comprises an inlet located near the leading edge of a lower surface of the wing and at least one outlet formed on the lower surface or on an upper surface of the wing.

	Flight controls - Enpsychlopedia (Site not responding. Last check: 2007-11-06)
		Spoilers - On very high lift/low drag aircraft like sailplanes, spoilers are used to disrupt airflow over the wing and greatly reduce the amount of lift.
		Air brakes - these are used on high speed aircraft and are intended to increase the drag of an aircraft without altering the amount of lift.
		Airbrakes and spoilers are sometimes the same device - on most airliners for example, the combined spoiler/airbrakes act to simultaneously remove lift and to slow the aircraft's forward motion.

		Air brake (aircraft) — In aeronautics these are a type of flight control system used on aircraft to reduce speed.

		Air brake (rail) — On larger road vehicles and railways this is a type of brake operated by compressed air.
