One or more illustrated papers glued at one point. Lifting a flap exposes the illustration directly beneath it. (see Lift-the-flap)
Parts of the wings that can be extended to help slow the plane for landing and increase lift at low speeds. Full flaps are typically used for landing, and partial flaps may also be used for takeoff.
Movable parts of the trailing edge of a wing that are used to increase lift (and drag) at slower air speeds. When a plane lands, the flaps are extended to increase lift and drag, to fly at a slower speed. Flaps increase lift by changing the shape of the airfoil.
The part of the plane that is deployed when landing or taking off. The flaps increase lift and decrease velocity.
moving sections of the trailing edge of the wing, on the inside of the ailerons. Used to create more lift at slower flying speeds, flaps are usually only found on rc airplanes with 5 or more channels.
Moveable parts of the trailing edge of a wing that are used to increase lift at slower air speeds. Flaps increase lift by changing the shape of the airfoil. A pilot will extend the flaps when the airplane is landing. By extending the flaps, the pilot is increasing the camber of the wing, the size of the wing and the wing's angle of attack. All of these actions will cause lift to decrease so the airplane can land more slowly.
Control surfaces on wings which increase lift for a given flight condition allowing a lower airspeed to be flown without stalling.
Control surfaces installed on the trailing edge of a wing and used to increase the amount of lift generated by the wing at slower speeds. Flaps also have the effect of slowing an aircraft during its landing approach.
A moveable part of the wing that is dropped into the airstream to increase lift and/or drag.
a movable airfoil that is part of an aircraft wing; used to increase lift or drag
hinged wing surfaces that are lowered to give more lift at low speeds
Hinged surfaces attached to the trailing edge of a wing, either to increase manoeuvrability (as on a control line aerobatic model) or to increase lift at the expense of drag (as on most full size aircraft and some radio control aeroplanes).
Flaps are movable control surfaces that are present on the trailing edge of the wing. Each together moves downward to give a wing extra lift. Flaps are considered to be flaps if each is separate from the aileron control surface. Flaps are typically placed on the in-board section of the wing's trailing edges (that's the part of the wing closest to the fuselage). When flaps are combined with ailerons, those surfaces are typically called flapperons. For those building kits that have German instructions, the word for flaps is Wolbklappen.
Moving parts at the trailing edge of the wings, on the inside of the ailerons, they are used to create lift at low speeds.
Hinged control surface located at the trailing edge of the wing inboard of the ailerons. The flaps are lowered to produce more aerodynamic lift from the wing, allowing a slower takeoff and landing speed. Flaps are often found on scale models, but usually not on basic trainers.
Pilot-controllable airfoils on the trailing edge of the wings, used to assist the pilot in takeoffs, slowflight, and landings. On takeoff, lowering or extending the flaps by 10 degrees (nominal) provides the highest lift-to-drag ratio and shortens the distance required to get airborne. Lowered flaps assist in slowflight by increasing drag and at the same time reducing the aircraft's stalling speed. On landing approaches, flaps are lowered - frequently all the way - to accommodate a steeper angle of descent, for instance for clearing obstacles or flying tight airport patterns. Flaps also permit touchdown at a lower airspeed, due to a higher coefficient of lift and thus a lower stalling airspeed. After touchdown, the drag of the flaps shortens the landing roll.
Integral areas of the inboard trailing edges of a wing which are extended by preset amounts in order to create more lift at low speed to assist takeoff and landing. Extending flaps by greater increments during the landing phase increases lift, steepens the glide and acts as an airbrake enabling slower approaches. Typical values would be 5º for take-off and 30º to 45º for the landing phase. Flaps are set flush to the wing profile during normal flight.
retractable trailing edges of a wing that move down to increase wing surface and increase lift on take-off. Located closer to the fuselage than the aileron
Hinged or pivoted airfoils forming part of the trailing edge of the wing and used to increase lift at reduced airspeeds. Flight plan: A formal, written plan of flight showing route, time en route, points of departure and destination, and other pertinent information.
