The Flap is a control surface found on some aircraft, usually located on the inboard trailing edge of each wing Flaps may be lowered to increase the lift of the aircraft by simulating an under-camber airfoil
The motion of anything broad and loose, or a stroke or sound made with it; as, the flap of a sail or the flap of a wing
a movable part on the wing surface which, when extended on takeoff or landing, increases lift or drag
(1) in copy preparation, a single piece of copy used more than once, which has changes on a piece of paper or an overlay The copy is then photographed with the flap up for one page and down for another, with the only differences being the contents of the flap (2) The portion of a dust jacket which wraps inside the front and back covers and is made visible by opening the cover (3) A protective covering of tissue over artwork, that is hinged at the top; also called Tissue Overlay to top
Surface mounted on the trailing edge of a wing to increase lift during take-off/landing
a movable airfoil that is part of an aircraft wing; used to increase lift or drag a movable piece of tissue partly connected to the body the motion made by flapping up and down pronounce with a flap, of alveolar sounds move noisily; "flags flapped in the strong wind
