[[File:Ailerons.jpg|thumb|300px|Ailerons (red) on the wings of a [[Cessna C172]]]]'''Ailerons''' are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft. The ailerons are used to control the aircraft in roll. The two ailerons are typically 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." | [[File:Ailerons.jpg|thumb|300px|Ailerons (red) on the wings of a [[Cessna C172]]]]'''Ailerons''' are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft.

[[File:Wingtip_device.jpg|thumb|300px|A wingtip device (red) on the wing of a [[Boeing 747]]]]'''Wingtip device'''s, sometimes know as winglets, are usually intended to improve the efficiency of fixed-wing [[aircraft]]. There are several types of devices, and though they function in different manners, the intended aerodynamic effect is to modify the aircraft's wake in some beneficial manner. Wingtip devices can also improve aircraft handling characteristics. From a marketing standpoint, they are also valued for their aesthetic appeal, and aircraft have been equipped with them for cosmetic reasons as well. | [[File:Wingtip_device.jpg|thumb|300px|A wingtip device (red) on the wing of a [[Boeing 747]]]]'''Wingtip device'''s, sometimes know as winglets, are usually intended to improve the efficiency of fixed-wing [[aircraft]].
