A centre stick (or center stick in the United States), or simply control stick is an aircraft cockpit arrangement where the control column (or joystick) is located in the center of the cockpit between the pilots or between the pilot's legs. 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. [1]

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.

The centre stick is used in many military fighter jets such as Eurofighter Typhoon and the Mirage III, but also in light aircraft such as Piper Cubs and the Diamond Aircraft line of products such as the DA20, DA40 and DA42.

This arrangement contrasts with the more recently developed "side-stick", which is used in such military fighter jets as the F-16, the F-35 Lightning II and Rafale and also on civil aircraft such as the Airbus A320.

History

The centre stick originated at the turn of the twentieth century. In 1900, Wilhelm Kress of Austria developed a control stick for aircraft, but did not apply for a patent. Instead, a patent was awarded to the French aviator, Robert Esnault-Pelterie who applied for it in 1907. [2]

Fixed-wing aircraft Heavier-than-air aircraft with fixed wings generating aerodynamic lift

A fixed-wing aircraft is a heavier-than-air flying machine, such as an airplane, which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, and ornithopters. The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft.

Aileron Aircraft control surface used to induce roll

An aileron is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll, which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'.

Cockpit Area from which a pilot controls an aircraft or vehicle

A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a pilot controls the aircraft.

Flight control surfaces Surface that allows a pilot to adjust and control an aircrafts flight attitude

Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.

Gloster E.28/39 British jet-engined aircraft, first flown in 1941

The Gloster E.28/39, was the first British jet-engined aircraft and first flew in 1941. It was the fourth jet to fly, after the German Heinkel He 178 (1939), the Italian Caproni Campini N.1 motorjet (1940), and the German Heinkel He 280 (1941).

Ejection seat Emergency aircraft escape system

In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft.

Aircraft flight control system How aircraft are controlled

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 as flight controls as they change speed.

Trainer aircraft Aircraft designed for training of pilots and aircrew

A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft.

Yakovlev Yak-141

The Yakovlev Yak-141, also known as the Yak-41, is a Soviet supersonic vertical takeoff/landing (VTOL) fighter aircraft designed by Yakovlev. It was used for testing.

HOTAS Man-machine interface concept for cockpit design

HOTAS, an acronym of hands on throttle-and-stick, is the concept of placing buttons and switches on the throttle lever and flight control stick in an aircraft's cockpit. By adopting such an arrangement, pilots are capable of performing all vital functions as well as flying the aircraft without having to remove their hands from the controls.

Stabilator

A stabilator, more frequently all-moving tail or all-flying tail, is a fully movable aircraft stabilizer. It serves the usual functions of longitudinal stability, control and stick force requirements otherwise performed by the separate parts of a conventional horizontal stabilizer and elevator. Apart from a higher efficiency at high Mach number, it is a useful device for changing the aircraft balance within wide limits, and for mastering the stick forces.

Chengdu J-10 Chinese multi-role fighter aircraft family

The Chengdu J-10 also known as Vigorous Dragon, is a medium-weight, single-engine, multirole combat aircraft capable of all-weather operations, configured with a delta wing and canard design, with fly-by-wire flight controls, and produced by the Chengdu Aircraft Corporation (CAC) for the People's Liberation Army Air Force (PLAAF), Pakistan Air Force (PAF) and People's Liberation Army Naval Air Force (PLANAF). The J-10 is mainly designed for air-to-air combat, but can also perform strike missions.

Yoke (aeronautics) Aircraft controls

A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft.

Combat flight simulators are vehicle simulation games, amateur flight simulation computer programs used to simulate military aircraft and their operations. These are distinct from dedicated flight simulators used for professional pilot and military flight training which consist of realistic physical recreations of the actual aircraft cockpit, often with a full-motion platform.

Avro Canada VZ-9 Avrocar 1959 experimental VTOL aircraft model

The Avro Canada VZ-9 Avrocar was a VTOL aircraft developed by Avro Canada as part of a secret U.S. military project carried out in the early years of the Cold War. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single "turborotor" blowing exhaust out of the rim of the disk-shaped aircraft. In the air, it would have resembled a flying saucer.

Bubble canopy

A bubble canopy is an aircraft canopy constructed without bracing, for the purpose of providing a wider unobstructed field of view to the pilot, often providing 360° all-round visibility.

Side-stick

A side-stick or sidestick controller is an aircraft control column that is located on the side console of the pilot, usually on the righthand side, or outboard on a two-seat flightdeck. Typically this is found in aircraft that are equipped with fly-by-wire control systems.

IAI Nammer

The IAI Nammer was a fighter aircraft developed in the Israeli aerospace manufacturing Israel Aerospace Industries (IAI) during the late 1980s and early 1990s. The programme was pursued as a private venture and the resultant aircraft was intended for the export market.

A blind flying panel is an instrumentation sub-panel located in the cockpit of an aircraft. Its purpose was to present the necessary information to pilots for flying under instrument flight rules (IFR); it would be used in circumstances where visual flight rules (VFR) would not be desirable or possible, such as during night time or unclear weather conditions. The blind flying panel was prevalently used during the Second World War upon a wide range of aircraft, from fighters such as the Supermarine Spitfire, to bombers and trainers alike. In the postwar era, it decreased in relevance following the increasing prevalence of onboard radar sets and other newer navigational aids.
