Flaps raise the maximum lift coefficient of the aircraft and therefore reduce its stalling speed. [5] They are used during low speed, high angle of attack flight including take-off and descent for landing. Some aircraft are equipped with "flaperons", which are more commonly called "inboard ailerons" [citation needed]. These devices function ...
Trailing edge flaps extended on the right on a typical airliner (an Airbus A310-300). Leading edge slats are also extended, on the left. A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the ...
An aircraft 'rolling', or 'banking', with its ailerons An aileron and roll trim tab of a light aircraft. An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. [1]
The most common high-lift device is the flap, a movable portion of the wing that can be lowered to produce extra lift. When a flap is lowered this re-shapes the wing section to give it more camber. Flaps are usually located on the trailing edge of a wing, while leading edge flaps are used occasionally. There are many kinds of trailing-edge flap.
High angle of attack protection may be lost and low energy (level flight stall) protection is lost. High speed and high angle of attack protections enter alternate law mode. [8] ALT1 may be entered if there are faults in the horizontal stabilizer, an elevator, yaw-damper actuation, slat or flap sensor, or a single air data reference fault. [7]
A flaperon (a portmanteau of flap and aileron) on an aircraft's wing is a type of control surface that combines the functions of both flaps and ailerons. Some smaller kitplanes have flaperons for reasons of simplicity of manufacture, while some large commercial aircraft such as the Boeing 747 , 767 , 777 , and 787 may have a flaperon between ...
Unusually the Halny was built with only one set of instruments and controls in the rear cockpit, thus the front seat can only be used by passengers. Full span flaps and coupled ailerons are fitted to the trailing edges, with the flaps able to deflect upwards for high speed flight and the ailerons drooping in sympathy with downward flap deflection.
Blown flaps, blown wing or jet flaps are powered aerodynamic high-lift devices used on the wings of certain aircraft to improve their low-speed flight characteristics. They use air blown through nozzles to shape the airflow over the rear edge of the wing, directing the flow downward to increase the lift coefficient .
