The deceleron, or split aileron, was developed in the late 1940s by Northrop, originally for use on the F-89 Scorpion fighter. It is a two-part aileron that can be deflected as a unit to provide roll control, or split open to act as an air brake .
Using ailerons causes adverse yaw, meaning the nose of the aircraft yaws in a direction opposite to the aileron application. When moving the aileron control to bank the wings to the left, adverse yaw moves the nose of the aircraft to the right. Adverse yaw is most pronounced in low-speed aircraft with long wings, such as gliders.
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.
The statement, "As it is the downwards deflection of an aileron that causes aileron drag, a simple way of eliminating adverse yaw would be to rely solely on the upward deflection of the opposite wing to cause the aircraft to roll." doesn't seem to make sense to me.

Control reversal is an adverse effect on the controllability of aircraft.The flight controls reverse themselves in a way that is not intuitive, so pilots may not be aware of the situation; to roll to the left, they have to push the control stick to the right, the opposite of the normal direction.

In some cases words have entered the English language by multiple routes - occasionally ending up with different meanings, spellings, or pronunciations, just as with words with European etymologies. Many entered English during the British Raj in colonial India. These borrowings, dating back to the colonial period, are often labeled as "Anglo ...
