The name "aileron", from French, meaning "little wing", also refers to the extremities of a bird's wings used to control their flight. [2] [3] It first appeared in print in the 7th edition of Cassell's French-English Dictionary of 1877, with its lead meaning of "small wing". [4] In the context of powered airplanes it appears in print about 1908.
Matthew Piers Watt Boulton (22 September 1820 – 30 June 1894), also published under the pseudonym M. P. W. Bolton, was a British classicist, elected member of the UK's Metaphysical Society, an amateur scientist and an inventor, best known for his invention of the aileron, a primary aeronautical flight control device.

The yaw plane translational equation, as in the pitch plane, equates the centripetal acceleration to the side force. = where (beta) is the sideslip angle, Y the side force and r the yaw rate. The moment equations are a bit trickier.
In applied fields the word "tight" is often used with the same meaning. [2] smooth Smoothness is a concept which mathematics has endowed with many meanings, from simple differentiability to infinite differentiability to analyticity, and still others which are more complicated. Each such usage attempts to invoke the physically intuitive notion ...
The Wrights' pioneering use of "roll control" by twisting the wings to change wingtip angle in relation to the airstream led to the more practical use of ailerons by their imitators, such as Glenn Curtiss and Henri Farman. The Wrights' original concept of simultaneous coordinated roll and yaw control (rear rudder deflection), which they ...
The Federal Aviation Administration said Saturday it will temporarily ground some Boeing 737 Max 9 airplanes used by U.S. airlines after a panel appeared to have detached from an Alaska Airlines ...
In mathematics, a plane is a two-dimensional space or flat surface that extends indefinitely. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. When working exclusively in two-dimensional Euclidean space, the definite article is used, so the Euclidean plane refers to the ...
