Fly-by-wire
Fly-by-wire (FBW) is a system that replaces the conventional aircraft flight control system#Hydro-mechanical, manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals, and flight control computers determine how to move the actuators at each control surface to provide the ordered response. Implementations either use Aircraft flight control system, mechanical flight control backup systems or else are fully electronic.Fly by Wire Flight Control Systems Sutherland Improved fully fly-by-wire systems interpret the pilot's control inputs as a desired outcome and calculate the control surface positions required to achieve that outcome; this results in various combinations of rudder, Elevator (a ...

Aircraft Flight Control System
A conventional Fixed-wing aircraft, fixed-wing aircraft flight control system (AFCS) 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 (fixed-wing aircraft), 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. Cockpit controls Primary controls Generally, the primary cockpit flight controls are arranged as follows:Langewiesche, WolfgangStick and Rudder: An Explanation of the Art of Flying McGraw-Hill Professional, 1990, , . * A Yoke (aircraft), control yoke (also known as a control column), cen ...

Side-stick
A side-stick or sidestick controller is an aircraft control stick 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.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 463. Aviation Supplies & Academics, 1997. The throttle controls are typically located to the left of a single pilot or centrally on a two-seat flightdeck. Only one hand is required to operate them; two handed operation is neither possible nor necessary. Prevalence The side-stick is used in many modern military fighter aircraft, such as the F-16 Fighting Falcon, Mitsubishi F-2, Dassault Rafale, and F-22 Raptor, F-35 Lightning 2, Chengdu J-20, AIDC F-CK 1 Ching-Kuo and also on civil aircraft, such as the Sukhoi Superjet 100, Airbus A320 and all subsequent Airbus aircraft, including the largest passenger jet in service, the Airbus A38 ...

Yoke (aircraft)
A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 563. Aviation Supplies & Academics, 1997. . The pilot uses the yoke to control the attitude of the plane, usually in both pitch and roll. Rotating the control wheel controls the ailerons and the roll axis. Fore and aft movement of the control column controls the elevator and the pitch axis. When the yoke is pulled back, the nose of the aircraft rises. When the yoke is pushed forward, the nose is lowered. When the yoke is turned left, the plane rolls to the left, and when it is turned to the right, the plane rolls to the right. Small to medium-size aircraft, usually limited to propeller-driven, feature a mechanical system whereby the yoke is connected directly to the control surfaces with cables and rods. Human muscle power alone is not enough for larger and more powerful aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A320 Flight Control
The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus. The A320 was launched in March 1984, Maiden flight, first flew on 22 February 1987, and was introduced in April 1988 by Air France. The first member of the family was followed by the stretched Airbus A321, A321 (first delivered in January 1994), the shorter Airbus A319, A319 (April 1996), and the shortest variant, the Airbus A318, A318 (July 2003). Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and Mobile, Alabama, in the United States since April 2016. The twinjet has a six-abreast economy cross-section and came with either CFM International CFM56, CFM56-5A or -5B, or IAE V2500 turbofan engines, except the A318. The A318 has either two CFM56-5B engines or a pair of Pratt & Whitney PW6000, PW6000 engines in place of the IAE V2500. The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners. Varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviator
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. Definition The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female pilot. The term ''aviator'' (''aviateur'' ...

Built-in Test Equipment
Built-in test equipment (BITE) for avionics primarily refers to passive fault management and diagnosis equipment built into airborne systems to support maintenance processes. Built-in test equipment includes multimeter A multimeter (also known as a multi-tester, volt-ohm-milliammeter, volt-ohmmeter or VOM, avometer or ampere-volt-ohmmeter) is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, elec ...s, oscilloscopes, discharge probes, and frequency generators that are provided as part of the system to enable testing and perform diagnostics. The acronym BIT is often used for this same function or, more specifically, in reference to the individual tests. BIT often includes: * The detection of the fault * The accommodation of the fault (how the system actively responds to the fault) * The annunciation or logging of the fault to warn of possible effects and/or aid in troubleshooting the faulty equipment.

Sensor
A sensor is often defined as a device that receives and responds to a signal or stimulus. The stimulus is the quantity, property, or condition that is sensed and converted into electrical signal. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are used in everyday objects such as touch-sensitive elevator buttons ( tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery ...

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining Orientation (geometry), orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, due to the angular momentum#Conservation of angular momentum, conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged Vibrating structure gyroscope#MEMS gyroscopes, MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring laser gyroscope, ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submer ...

Groundcrew
In all forms of aviation, ground crew (also known as ground operations in civilian aviation) are personnel that service aircraft while on the ground, during routine turn-around; as opposed to aircrew, who operate all aspects of an aircraft whilst in flight. The term ground crew is used by both civilian commercial airlines and in military aviation. Aircraft ground crew Dependent on the type of aircraft being operated, airline ground crew members typically include: airframe technicians, engine technicians, avionics technicians. Military aircraft Military aircraft equipped with either weapons and / or an ejector seat will also require a dedicated weapons technician ground crew member. Non-powered flight Ground crew required for non-powered flight, such as gliders will include people who manually handle the glider aircraft from their storage location (such as an aircraft hangar) to their respective launch site, and then to return them at the end of flying.
