The earliest form of roll control was produced by warping the whole wing. Raising the trailing edge of the right hand wing and lowering the trailing edge of the left hand wing will result in the aircraft rolling to the right. See also: Ailerons.
A twisting of the tips of an airplane's wings, up on one side and down on the other, used to make an airplane roll.
A method of control in roll that bent ('warped') the trailing edge of the wing, by means of external cables, to alter lift. The effect was the same as an aileron, but meant that the wing could not be built of strong inflexible materials. However, the wing had to be strong enough to be safe and so the range of deflection was always limited. These draw-backs meant that wing warping was gradually replaced by aileron control.
