aircraft ailerons?

Answer 1

Ailerons are the hinged control surfaces located near the wing tips. The ailerons on both wings work together in order to bank the airplane.

When the wheel is turned to the right, the right aileron is deflected upward and the left aileron is deflected downwards. This has the effect of decreasing the amount of lift produced by the right wing and increasing the amount of lift produced by the left wing.

Answer 2

Ailerons are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft. They are used to control the aircraft in roll. The two ailerons are interconnected so that one goes down when the other goes up: the downgoing aileron increases the lift on its wing while the upgoing aileron reduces the lift on the other wing, producing a rolling moment about the aircraft's longitudinal axis. The word aileron is French for "little wing."

An unwanted side-effect of aileron operation is adverse yaw — a yawing moment in the opposite direction to the turn generated by the ailerons. In other words, using the ailerons to roll an aircraft to the right would produce a yawing motion to the left. It is caused by an increase in induced drag due to the greater effective camber of the wing with a downward-deflected aileron, and the opposite effect on the other wing. Modern aileron systems have minimal adverse yaw, such that it is barely noticeable in most turns. This may be accomplished by the use of differential ailerons, which have been rigged such that the downgoing aileron deflects less than the upward-moving one. Frise ailerons achieve the same effect by protruding beneath the wing of an upward deflected aileron, increasing drag on that side. Ailerons may also use a combination of these methods.

Adverse yaw is also caused by the wing on the outside of the turn traveling faster than the inside wing and thus having more lift and drag. Once the desired angle of bank (degree of rotation on the longitudinal axis) is obtained, the pilot uses opposite aileron to prevent the aircraft from continuing to roll due to this increased lift. This minor opposite use of the control must be maintained throughout the turn. The pilot also uses a slight amount of rudder in the same direction as the turn to counteract adverse yaw and to produce a "coordinated" turn where the fuselage is parallel to the flight path. A simple gauge on the instrument panel called the inclinometer, also known as "the ball", indicates when this coordination is achieved.


Ailerons are the trailing-edge control surface nearest the wing tip (although on some airliners they can also be found at the wing root). On this parked Piper Cherokee the aileron has deflected downwards.The device first appeared on a monoplane, built by New Zealand inventor Richard Pearse in 1902, but most researchers believe the aircraft achieved no more than short, poorly controlled flights. The first aircraft accepted to have had a fully controlled flight using an aileron was 14 Bis by Santos Dumont. It was later developed independently by the Aerial Experiment Association, headed by Alexander Graham Bell, and by Robert Esnault-Pelterie, a French aircraft builder. Ailerons superseded the earlier wing warping technique, developed by the Wright Brothers.

A control surface that combines an aileron and flap is called a flaperon. A single surface on each wing serves both purposes: used as an aileron, the flaperons left and right are actuated differentially; when used as a flap, both flaperons are actuated downwards. As an example of an aircraft using flaperons, see this RJ.03 IBIS experimental aircraft. Please note that when a flaperon is actuated downwards (i.e. used as a flap) there is enough freedom of movement left to be able to still use the aileron function.

A further form of roll control, common on modern jet transport aircraft, utilises spoilers in conjunction with ailerons.

Answer 4

Ailerons are control surfaces that change the airflow, and speed, over the main wings. By changing the lift of each wing with these controls, the airframe will roll, or bank.

Answer 5

Roll the fuaslage to the right or left this allows the aircraft to bank into turns.

Answer 6

Located on the trailing edge of the wing near the tips, are control surfaces that when the yoke or wheel, is turned left or right, cause the plane to bank, or roll.

Answer 7

they make the aircraft turn and bank left or right

Answer 8

aile, meaning wing, from Old French
