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 aileron roll is commonly executed through the application of full aileron in one direction. In some lower powered general aviation and aerobatic training aircraft, prior to applying aileron input, the pilot must begin the maneuver by trading altitude for airspeed (i.e. diving). This helps achieve enough airspeed to complete the roll without ...
Basic aircraft control surfaces and motion. A)aileron B)control stick C)elevator D)rudder. Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft.
Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...
Spoilerons roll an aircraft by reducing the lift of the downward-going wing.Unlike ailerons, spoilers do not increase the lift and drag of the upward-going wing. A raised spoileron increases the drag on the down-going wing where it is deployed, causing the aircraft to yaw in the direction of the turn.
Some aircraft use lift spoilers on landing approach to control descent without changing the aircraft's attitude. One jet airliner not fitted with lift spoilers was the Douglas DC-8 which used reverse thrust in flight on the two inboard engines to control descent speed (however the aircraft was fitted with lift dumpers).
In more modern aircraft, inputs may first be sent to a fly-by-wire system, which then sends a corresponding signal to actuators attached to the aileron booster systems and control surfaces. Yokes may feature a stick shaker , which is designed to help indicate the onset of stall , or even a stick pusher , which physically pushes the yoke to ...
It has been assessed to be considerably valuable for missiles requiring a high level of maneuverability, as used in shorter-range dogfights between fighter aircraft. [1] An early adopter of the rolleron was the AIM-9 Sidewinder, a prominent air-to-air missile. Such devices are present on all four of its rear wings.
