TAM Transportes Aéreos Regionais Flight 402
TAM Transportes Aéreos Regionais Flight 402 was a scheduled domestic flight from São Paulo–Congonhas International Airport in São Paulo, Brazil to Recife International Airport in Recife via Santos Dumont Airport in Rio de Janeiro. On 31 October 1996, at 8:27 ( UTC-2), the starboard engine of the Fokker 100 operating the route reversed thrust while the aircraft was climbing away from the runway at Congonhas. The aircraft stalled and rolled beyond control to the right, then struck two buildings and crashed into several houses in a heavily populated area only 25 seconds after takeoff. All 95 people on board were killed, as well as another 4 on the ground. It is the fourth deadliest accident in Brazilian aviation history, the second at the time. It is also the deadliest aviation accident involving a Fokker 100. Aircraft The aircraft involved was a Fokker 100 with the registration PT-MRK. The aircraft made its first flight on 8 February 1993 and was acquired second-hand by TAM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Reverser
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones. Reverse thrust is also available on many propeller-driven aircraft through reversing the controllable-pitch propellers to a negative angle. The equivalent concept for a ship is called astern propulsion. Principle and uses A landing roll consists of touchdown, bringing the aircraft to taxi speed, and eventually to a complete stop. However, most commercial jet engines continue to produce thrust in the forward direction, even when idle, acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lauda Air Flight 004
Lauda Air Flight 004 was a regularly scheduled international passenger flight from Bangkok, Thailand, to Vienna, Austria. On May 26, 1991, the Boeing 767-300ER operating the service crashed, following an uncommanded midair deployment of the thrust reverser on the No.1 engine, causing the aircraft to enter an aerodynamic stall, uncontrolled dive, and break up midair, killing all 213 passengers and ten crew members on board. It is the deadliest aviation incident involving the Boeing 767, the deadliest of its kind, and the deadliest aviation incident in Thailand's history as of 2022. The crash marked the aircraft type's first fatal incident and third hull loss. Formula One world motor racing champion Niki Lauda, who founded and ran Lauda Air, was personally involved in the accident investigation.

Fokker
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autothrottle
An autothrottle (automatic throttle, also known as autothrust, A/T) is a system that allows a pilot to control the power setting of an aircraft's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow. The autothrottle can greatly reduce the pilots' work load and help conserve fuel and extend engine life by metering the precise amount of fuel required to attain a specific target indicated air speed, or the assigned power for different phases of flight. A/T and AFDS (Auto Flight Director Systems) can work together to fulfill the whole flight plan. Working modes There are two parameters that an A/T can maintain, or try to attain: speed and thrust. In speed mode the throttle is positioned to attain a set target speed. This mode controls aircraft speed within safe operating margins. For example, if the pilot selects a target speed which is slower than stall speed, or a speed faster than maximum speed, the autothrottle system will maint ...

Short Circuit
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes. Definition A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. In circuit analysis, a ''short circuit'' is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' ...

Attendance at the exhibition was over half a million, and after it closed, several Dutch commercial interests intended to establish a Dutch airline, which Plesman was nominated to head. In September 1919, Queen Wilhelmina awarded the yet-to-be-founded KLM its "Royal" ("''Koninklijke''") p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Miniature Snap-action Switch
A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism. Switching happens reliably at specific and repeatable positions of the actuator, which is not necessarily true of other mechanisms. They are very common due to their low cost but high durability, greater than 1 million cycles, and up to 10 million cycles for heavy-duty models. This durability is a natural consequence of the design. The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Most successful designs also exhibit hysteresis, meaning that a small reversal of the actuator is insufficient to reverse the contacts; there must be a significant movement in th ...
