1909, from French aileron, altered (by influence of aile "wing"), from French aleron "little wing," diminutive of Old French ele "wing" (12c.), from Latin ala "wing& [..]

The movable areas of a wingform that control or affect the roll of an aircraft by working opposite one another—up-aileron on the right wing and down-aileron on the left wing. French: aileron [..]

A control surface located on the trailing edge of each wing tip. Deflection of these surfaces controls the roll or bank angle of the aircraft.

(n) an airfoil that controls lateral motion

Control surfaces on the trailing edge of the wing. Ailerons on each side of the airplane deflect in opposite directions to control the roll, or bank, of the aircraft. Movement of the ailerons is controlled by either the control yoke or side stick. A trim system minimizes the force needed to hold the ailerons in the proper position for various fligh [..]

The movable areas of a wing form that control or affect the roll of an aircraft by working opposite one another -- up-aileron on the right wing and down-aileron on the left wing.

A control surface on fixed-wing aircraft, usually mounted on the aft edge of wings, that controls roll, and is controlled by the wheel; Symbols: delta sub A; Typical Units: rad, deg;

An adjustable ‘control surface’ on the trailing edge a plane wing that can be raised or lowered to cause rolling to the left and right. Raising the aileron on one wing and lowering the one on the othe [..]

An aileron is the winged control surface that causes a plane to roll or strafe to the left and right. Aileron is more commonly referred to as roll in reference to multicopters. It is controlled by the [..]

A control surface located on the trailing edge of each aircraft wing tip. Deflection of these surfaces controls the roll or bank angle of the aircraft.

These ingenious flight control surfaces on the trailing edge of the wing were invented by birds. (Don't write me about pterosaurs being first - they flexed the whole wing to bank, though the prin [..]

Airman’s Information Manual – A primary FAA publication whose purpose is to instruct airmen about operating in the US airspace system.

A hinged control surface on the wing that scares the hell out of airline passengers when it moves.

A trailing-edge wing control surface used to roll aircraft.

A control surface on fixed-wing aircraft, usually mounted on the aft edge of wings, that controls roll, and is controlled by the wheel; Symbols: delta sub A; Typical Units: rad, deg;

Movable surface on the outboard trailing edge of each wing. Operated by rotating the control wheel (or tilting the stick from side to side), the ailerons control roll (animation).

A small hinged portion of an airplane’s wing, used to make an airplane roll, or turn around its long axis.

Control surfaces hinged at the back of the wings which by deflecting up or down help to bank the airplane.

A hinged surface on the wing of an aircraft or spacecraft used to adjust the craft's angle of flight.

The hinged part on the trailing edge of an airplane wing, used to control lateral turns. A half gable, as at the end of a penthouse or of the aisle of a church.
