Airbus Industrie Flight 129 was a test flight of an Airbus Industrie A330-321 that ended in a crash on 30 June 1994 at Toulouse–Blagnac Airport, killing all seven people aboard. The last test flown was to certify the plane's takeoff capability with a single engine failure. It was the first fatal accident involving an Airbus A330 as well as the first hull loss of the type. Aircraft The aircraft involved in the accident was an Airbus A330-321, registration F-WWKH, c/n 42. Equipped with twin Pratt & Whitney PW4164 powerplants, it first flew on 14 October 1993. The aircraft was days old at the time of the accident. The aircraft belonged to Thai Airways International and was being flight-tested under agreement with the owner. Airbus Industrie already owed Thai Airways compensation for the hull loss of another plane it had damaged during testing in December 1993. Test objectives The objective of the flight was to test the performance of the aircraft in simulated engine fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Error
In aviation, pilot error generally refers to an action or decision made by a Aircraft pilot#Airline, pilot that is a substantial contributing factor leading to an Aviation accidents and incidents, aviation accident. It also includes a pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention on International Civil Aviation, Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of "pilot error" does not include deliberate crashing (and such crashes are not classified as accidents). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs ...

Autopilot
An autopilot is a system used to control the path of a vehicle without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes Colloquialism, colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"; "George is flying the plane now".''). The etymology of the nickname is unclear: some claim it is a reference to American inventor George De Beeson (1897–1965), who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to Ki ...

Attitude Control (fixed-wing Aircraft)
Spacecraft attitude control is the process of controlling the orientation of a spacecraft (vehicle or satellite) with respect to an inertial frame of reference or another entity such as the celestial sphere, certain fields, and nearby objects, etc. Controlling vehicle attitude requires actuators to apply the torques needed to orient the vehicle to a desired attitude, and algorithms to command the actuators based on the current attitude and specification of a desired attitude. Before and during attitude control can be performed, spacecraft attitude determination must be performed, which requires sensors for absolute or relative measurement. The broader integrated field that studies the combination of sensors, actuators and algorithms is called '' guidance, navigation and control'', which also involves non-attitude concepts, such as position determination and navigation. Motivation A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takeoff/go-around Switch
A takeoff/go-around switch (TO/GA or TOGA; ) is a switch on the autothrottle of modern large aircraft, with two modes: takeoff (TO) and go-around (GA). The mode is dependent on the phase of flight; usually, on approach to land, the autopilot will be set to approach mode, therefore if the TO/GA switch is pressed it will activate the go-around mode of the autothrottle (about 90–92% N1, if pressed again, go around thrust will increase to full (100+% N1); conversely, when takeoff is set on the autopilot, the switch activates takeoff mode of the autothrottle. On Boeing aircraft, TO/GA modes are selected by a separate button near the throttle levers; on Airbus aircraft, it is activated by advancing the thrust levers forward to the TO/GA detent. Usage in takeoff Once an aircraft has lined up on the runway, the pilots first increase the engine power to 40–60% N1 (low-pressure compressor RPM) on Boeing aircraft, and 50% N1 on Airbus aircraft. Large jet engines accelerate slowly from i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airspeed
In aviation, airspeed is the speed of an aircraft relative to the air it is flying through (which itself is usually moving relative to the ground due to wind). In contrast, the ground speed is the speed of an aircraft with respect to the surface of the Earth (whether over land or presumed-stationary water). It is difficult to measure the exact airspeed of the aircraft (true airspeed), but other measures of airspeed, such as indicated airspeed and Mach number give useful information about the capabilities and limitations of airplane performance. The common measures of airspeed are: * Indicated airspeed (IAS), what is read on an airspeed gauge connected to a pitot-static system. * Calibrated airspeed (CAS), indicated airspeed adjusted for pitot system position and installation error. * True airspeed (TAS) is the actual speed the airplane is moving through the air. When combined with aircraft direction, wind speed and direction, it can be used to calculate ground speed and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airbus
Airbus SE ( ; ; ; ) is a Pan-European aerospace corporation. The company's primary business is the design and manufacturing of commercial aircraft but it also has separate Airbus Defence and Space, defence and space and Airbus Helicopters, helicopter divisions. Airbus has long been the world's leading helicopter manufacturer and, in 2019, also emerged as the world's biggest manufacturer of airliners. The company was incorporated as the European Aeronautic Defence and Space Company (EADS) in the year 2000 through the merger of the French Aérospatiale-Matra, the German DASA and Spanish EADS CASA, CASA. The new entity subsequently acquired full ownership of its subsidiary, ''Airbus Industrie GIE'', a joint venture of European aerospace companies originally incorporated in 1970 to develop and produce Airbus A300, a wide-body aircraft to compete with American-built airliners. EADS rebranded itself as ''Airbus SE'' in 2015. Reflecting its multinational origin, the company operates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alitalia
Alitalia - Società Aerea Italiana S.p.A., operating as Alitalia (), was an Italian airline which was once the flag carrier and largest airline of Italy. The company had its head office in Fiumicino, in the Metropolitan City of Rome Capital. The airline was owned by the Government of Italy as a Nationalization, nationalized business from its founding in 1946 until it was Privatization, privatized in 2009. However, it struggled with profitability whilst operating as a private company, including failed negotiations to sell to other private parties. The airline entered extraordinary Administration (law), administration in 2017 following many years of financial losses. The Italian government eventually took back ownership of the airline in March 2020.
