Yaw string used in front of the cockpit of an F-14D Tomcat. In flight, pilots are instructed to step on the head of the yaw string; the head is the front of the string, where the string is attached to the aircraft. If the head of the yaw string is to the right of the yaw string tail, then the pilot should apply right rudder pressure.
Spoiler controls can be used for roll control (outboard or mid-span spoilers) or descent control (inboard spoilers). Some aircraft use spoilers in combination with or in lieu of ailerons for roll control, primarily to reduce adverse yaw when rudder input is limited by higher speeds.
Diagram of the Wright brothers' 1899 kite, showing wing bracing and strings attached to hand-held sticks used for warping the wing while in flight. The Wright brothers' first powered aircraft, which utilized warping wings. Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft or kite.
Yaw – in which the nose of the airplane moves left or right. This is typically controlled by the rudder at the rear of the airplane. Roll (bank) – in which one wing of the airplane moves up and the other moves down. This is typically controlled by ailerons on the wings of the airplane.
Another aircraft with full-length double-slotted flaps was the Wren 460. To go with large aileron deflections at low speeds [5] it had a set of five feathering drag plates ahead of each aileron to overcome adverse aileron yaw and decrease lift on the low wing. [6] Boeing's line of jet airliners have flight spoilers which can act as roll ...
Boeing 777 flaperon Flaperons on a Denney Kitfox Model 3, built in 1991 Flaperons (Junkers style) on an ICP Savannah Model S, built in 2010 Work of the flaperon of Boeing 777. 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.
Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface.
A winglet on a KC-135 Stratotanker with attached tufts showing airflow during NASA tests in 1979–80.. In aeronautics, tufts are pieces of yarn or string, typically around 15 cm (6 in) long, attached to an aircraft surface in a grid pattern and imaged during flight.
