In ultralight aircraft and motorized hang gliders, for example, there is no mechanism at all. In some aircraft, the control surfaces are not manipulated with a linkage. Flight control has long been taught in such fashion for many decades, as popularized in ab initio instructional books such as the 1944 work Stick and Rudder. The basic pattern for modern flight controls was pioneered by French aviation figure Robert Esnault-Pelterie, with fellow French aviator Louis Blériot popularizing Esnault-Pelterie's control format initially on Louis' Blériot VIII monoplane in April 1908, and standardizing the format on the July 1909 Channel-crossing Blériot XI. Some are directly connected to the control surfaces using cables, others (fly-by-wire airplanes) have a computer in between which then controls the electrical actuators.īlériot VIII at Issy-les-Moulineaux, the first flightworthy aircraft design to have the initial form of modern flight controls for the pilotĮven when an aircraft uses variant flight control surfaces such as a V-tail ruddervator, flaperons, or elevons, to avoid pilot confusion the aircraft's flight control system will still be designed so that the stick or yoke controls pitch and roll conventionally, as will the rudder pedals for yaw. Centre sticks also vary between aircraft. There are yokes where roll is controlled by rotating the yoke clockwise/counterclockwise (like steering a car) and pitch is controlled by moving the control column towards or away from the pilot, but in others the pitch is controlled by sliding the yoke into and out of the instrument panel (like most Cessnas, such as the 152 and 172), and in some the roll is controlled by sliding the whole yoke to the left and right (like the Cessna 162). The control yokes also vary greatly amongst aircraft. throttle controls to control engine speed or thrust for powered aircraft.rudder pedals, or the earlier, pre-1919 "rudder bar", to control yaw, which move the rudder left foot forward will move the rudder left for instance.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 aircraft designs) when turned or deflected left and right, and moves the elevators when moved backwards or forwards.Generally, the primary cockpit flight controls are arranged as follows: Cockpit controls and instrument panel of a Cessna 182D Skylane
