Flex Temp
Flex temp is a technique used to produce cost savings through increased engine life and reduced overhaul and fuel costs for airliners by allowing them to takeoff, take-off at less than rated thrust. For Airbus and Fokker aircraft the technique is known as ''flex temp'' or just ''flex''. Other manufacturers use the terms ''Assumed temperature thrust reduction'', ''Reduced take-off thrust'' or ''Factored take-off thrust''. Technique The runway length required for an aircraft to take off depends on a number of things including aircraft weight, flap setting and environmental conditions. The particular take-off distance required may be less than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature. At this temperature the engine is now running at its turbine temperature limit which is displ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takeoff
Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway. For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier and the Bell Boeing V22 Osprey), no runway is needed. Horizontal Power settings For light aircraft, usually full power is used during takeoff. Large transport category (airliner) aircraft may use a reduced power for takeoff, where less than full power is applied in order to prolong engine life, reduce maintenance costs and reduce noise emissions. In some emergency cases, the power used can then be increased to increase the aircraft's performance. Before takeoff, the engines, particularly piston engines, are routinely run up at high power to check for engine-related problems. The airc ...

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] |
Flight Management System
A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. Using various sensors (such as GPS and INS often backed up by radio navigation) to determine the aircraft's position, the FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD). The FMS can be summarised as being a dual system consisting of the Flight Management Computer (FMC), CDU and a cross talk bus. The modern FMS w ...

Takeoff/go-around Switch
A takeoff/go-around switch (TO/GA; ) 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; 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 switch near the throttle levers, but on Airbus aircraft it is activated by pushing the thrust levers fully forward to the TO/GA detent. Takeoff Once an aircraft has lined up, 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 idle to approximately 40%, and stabilising the engines prior to applying full power prevents a large thrust asymme ...

Emirates Flight 407
Emirates Flight 407 was a scheduled international passenger flight operated by Emirates from Auckland to Dubai with a stopover in Melbourne, operated by an Airbus A340-500 aircraft. On 20 March 2009, the flight failed to take off properly at Melbourne Airport, hitting several structures at the end of the runway before climbing and then returning to the airport for a safe landing. Although no fatalities or injuries resulted, damage to the aircraft was severe enough for the event to be classified by Australian Transport Safety Bureau as an "accident". It was subsequently determined that a data-entry error resulted in insufficient engine thrust during take off. It has been described "as close as we have ever come to a major aviation catastrophe in Australia" by aviation officials. Chronology The scheduled flight departed from Melbourne as planned at 22:30 using runway 16, which was long. The captain ordered the first officer to rotate before the end of the runway, travelling at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
