⭐ Core Definition: Aircraft flight control system

A conventional fixed-wing aircraft flight control system consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered flight controls as they change speed.

The fundamentals of aircraft controls are explained in flight dynamics. This article centers on the operating mechanisms of the flight controls. The basic system in use on aircraft first appeared in a readily recognizable form as early as April 1908, on Louis Blériot's Blériot VIII pioneer-era monoplane design.

👉 Aircraft flight control system in the context of Wright brothers

The Wright brothers, Orville Wright (August 19, 1871 – January 30, 1948) and Wilbur Wright (April 16, 1867 – May 30, 1912), were American aviation pioneers generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of an engine-powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, four miles (6 km) south of Kitty Hawk, North Carolina, at what is now known as Kill Devil Hills. In 1904 the Wright brothers developed the Wright Flyer II, which made longer-duration flights including the first circle, followed in 1905 by the first truly practical fixed-wing aircraft, the Wright Flyer III.

The brothers' breakthrough invention was their creation of a three-axis control system, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. Their system of aircraft controls made fixed-wing powered flight possible and remains standard on airplanes of all kinds. Their first U.S. patent did not claim invention of a flying machine, but rather a system of aerodynamic control that manipulated a flying machine's surfaces. From the beginning of their aeronautical work, Wilbur and Orville focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines. Using a small home-built wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design more efficient wings and propellers.

Aircraft flight control system in the context of Wingsuiting

Wingsuit flying (or wingsuiting) is the sport of skydiving using a webbing-sleeved jumpsuit called a wingsuit to add webbed area to the diver's body and generate increased lift, which allows extended air time by gliding flight rather than just free falling. The modern wingsuit, first developed in the late 1990s, uses a pair of fabric membranes stretched flat between the arms and flanks/thighs to imitate an airfoil, and often also between the legs to function as a tail and allow some aerial steering.

Like all skydiving disciplines, a wingsuit flight almost always ends by deploying a parachute, and so a wingsuit can be flown from any point that provides sufficient altitude for flight and parachute deployment – a drop aircraft, or BASE-jump exit point such as a tall cliff or mountain top. The wingsuit flier wears parachuting equipment specially designed for skydiving or BASE jumping. While the parachute flight is normal, the canopy pilot must unzip arm wings (after deployment) to be able to reach the steering parachute toggles and control the descent path.

Aircraft flight control system in the context of Thrust vectoring

Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.

In rocketry and ballistic missiles that fly outside the atmosphere, aerodynamic control surfaces are ineffective, so thrust vectoring is the primary means of attitude control. Exhaust vanes and gimbaled engines were used in the 1930s by Robert Goddard.

Aircraft flight control system in the context of Hydraulic fluid

A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery.

Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility.

Aircraft flight control system in the context of Centre stick

A centre stick (spelled center stick in American English), or simply control stick, is an aircraft cockpit arrangement where the control column (or joystick) is located in the center of the cockpit either between the pilot's legs or between the pilots' positions. Since the throttle controls are typically located to the left of the pilot, the right hand is used for the stick, although left-hand or both-hands operation is possible if required.

The centre stick is a part of an aircraft's flight control system and is typically linked to its ailerons and elevators, or alternatively to its elevons, by control rods or control cables on basic aircraft. On heavier, faster, more advanced aircraft the centre stick may also control power-assist modules. Modern aircraft centre sticks are also usually equipped with a number of electrical control switches within easy finger reach, in order to reduce the pilot's workload.

Aircraft flight control system in the context of Navalised aircraft

A navalised aircraft (or navalized aircraft) is an aircraft that is designed for naval usage. A navalised aircraft specifically designed to take off and land from the flight deck of an aircraft carrier is called a carrier-based aircraft.

Navalised aircraft include both fixed-wing (including seaplanes, biplanes, monoplanes and flying wings, both propeller- and jet-propelled) and rotary-wing aircraft (helicopters, tiltrotors and, in some cases, multicopters). In many cases, the aircraft is simply a modified variant of a land-based model. They are different to land-based aircraft in that they are designed to tolerate greater corrosion due to humidity and salt weathering around marine environments, handle increased mechanical stress due to harsher air conditions such as strong sea breezes and extreme weathers, and often need to operate on moving vessels at sea, which typically dictates more complex flight control to deal with unsteady sea state and also the ability to perform vertical/short takeoff and landing as there are very limited runway spaces available (or none at all) on deck.

Aircraft flight control system in the context of Hover (helicopter)

Helicopter flight controls are used to achieve and maintain controlled aerodynamic helicopter flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a desired way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades cyclically during rotation, creating differing amounts of lift at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades collectively by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration.

A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a mixing unit, a mechanical or hydraulic device that combines the inputs from both and then sends along the "mixed" input to the control surfaces to achieve the desired result. The manual throttle may also be considered a flight control because it is needed to maintain rotor speed on smaller helicopters without governors. The governors also help the pilot control the collective pitch on the helicopter's main rotors, to keep a stable, more accurate flight.

Aircraft flight control system in the context of CTOL

A conventional take-off and landing (CTOL), also known as horizontal take-off and landing (HTOL), is the usual process whereby fixed-wing aircraft perform takeoff and landing. As fixed-wing aircraft must have a forward motion to have relative air flow over the airfoils (wings) in order to generate lift, they require a period of ground acceleration before takeoff and conversely also a period of safe, gradual ground deceleration after landing, both translating to the necessity of sufficient distance for linear ground movement, which conventionally involve the use of dedicated runways.

During takeoff, the aircraft will first taxi or be tugged into a launch position at one end of the runway, where a final preflight check known as the run-up is completed. When cleared to proceed, the aircraft engines power up and the aircraft, propelled by the engines' thrust, begins accelerating down the runway in a takeoff roll with its landing gear wheels still contacting the ground. The takeoff roll ends when sufficient speed has been reached for the wings to generate more lift than the combined weight of the aircraft and its payloads, at which point the pilot manipulates the flight controls to pitch up the aircraft and raise the angle of attack of the wings, which further increases their lift coefficient and causes the aircraft to finally break contact with the ground (i.e. the liftoff) and transition into actual flight.
