Fokker 100
The Fokker 100 is a regional jet that was produced by Fokker in the Netherlands. The Fokker 100 was based on the Fokker F28 with a fuselage stretched by to seat up to 109 passengers, up from 85. It is powered by two newer Rolls-Royce Tay turbofans, and it has an updated glass cockpit and a wider wing and tail for increased maximum weights. The Fokker 70 is a shortened variant that can hold up to 85 passengers and was developed for shorter routes, which first flew in April of 1993. The program was announced in 1983 and it made its maiden flight on 30 November 1986. The variant was approved on 20 November 1987, and first deliveries to Swissair started in February 1988. American Airlines ordered 75, TAM Transportes Aéreos Regionais asked for 50, and USAir got 40. Fokker had financial troubles and went bankrupt in March 1996, and production ended in 1997 after 283 deliveries. Amsterdam-based Rekkof group wants to restart its production and update it with new engines, but has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease.

Glass Cockpit
A glass cockpit is an aircraft cockpit that features an array of electronic (digital) flight instrument display device, displays, typically large liquid-crystal display, LCD screens, rather than traditional Analog device, analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays and a primary flight display driven by flight management systems, that can be adjusted to show flight information as needed. This simplifies aircraft operation and navigation and allows aviator, pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. In recent years the technology has also become widely available in small aircraft. As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscope, gyroscopic fli ...

Autothrust
An autothrottle (automatic throttle; also known as autothrust, A/T, or A/THR) is a system that allows a aviator, pilot to control the power setting of an aircraft's Aircraft engine, engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow. The autothrottle can greatly reduce the pilots' workload 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: Airspeed, speed and thrust. In speed mode the throttle is positioned to attain a set target speed, subject to safe operating margins. For example, if the pilot selects a target speed which is slower than Stall (flight), stall speed, the autothrottle system maintains a speed ...

Autoland
In aviation, autoland describes a system that fully automates the landing procedure of an aircraft's flight, with the flight crew supervising the process. Such systems enable airliners to land in weather conditions that would otherwise be dangerous or impossible to operate in. A few general aviation aircraft have begun to be fitted with "emergency autoland" systems that can be activated by passengers, or by automated crew monitoring systems. The emergency autoland systems are designed to complete an emergency landing at the nearest suitable airport, without any further human intervention, in the event that the flight crew is incapacitated. Description Autoland systems were designed to make landing possible in visibility too poor to permit any form of visual landing, although they can be used at any level of visibility. They are usually used when visibility is less than 600 meters runway visual range and/or in adverse weather conditions, although limitations do apply for most air ...

Flight Director (aeronautics)
In aviation, a flight director (FD) is a flight instrument that is overlaid on the attitude indicator that shows the aviator, pilot of an aircraft the attitude required to execute the desired flight path. Flight directors are mostly commonly used during final approach, approach and landing. They can be used with or without autopilot systems. Description Flight director (FD) modes integrated with autopilot systems perform calculations for more advanced automation, like "selected course (intercepting), changing altitudes, and tracking navigation sources with cross winds." FD computes and displays the proper pitch and bank angles required for the aircraft to follow a selected flight path. The flight director usually receives input from an Air Data Computer (ADC) and a flight data computer. The ADC supplies altitude, airspeed and temperature data, heading data from magnetic sources such as flux valves, heading selected on the Horizontal Situation Indicator (HSI) (or Primary flight ...

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 F ...

Horizontal Stabilizer
A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail ( empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chord (aeronautics)
In aeronautics, the chord is an imaginary straight line segment joining the leading edge and trailing edge of an aerofoil cross section parallel to the direction of the airflow. The chord length is the distance between the trailing edge and the leading edge. L. J. Clancy (1975), ''Aerodynamics'', Section 5.2, Pitman Publishing Limited, London. The point on the leading edge used to define the main chord may be the surface point of minimum radius. p.18 For a turbine aerofoil, the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up. The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term ''chord'' or ''chord length'' is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direc ...

Re-engine
The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Similar to, but more exacting than, the usual engineering design process, the technique is highly iterative, involving high-level configuration tradeoffs, a mixture of analysis and testing and the detailed examination of the adequacy of every part of the structure. For some types of aircraft, the design process is regulated by civil airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs. Design constraints Purpose The design process starts with the aircraft's intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency whereas fighter jets are designed to perform ...

Rekkof
Fokker Next Gen NV (formerly Rekkof Restart - from ''Fokker'' spelled backwards, Rekkof Aircraft, and Netherlands Aircraft Company) is a Dutch company dedicated to develop and manufacture a hydrogen-powered regional airliner. History Initially known as ''Rekkof Restart'' when the company was established in 1996, the company's intention was to restart the production of upgraded versions of the Fokker 70 and Fokker 100 regional jets as production of those stopped when Fokker was declared bankrupt in 1996. The initial plan was to start building unmodified versions of both the Fokker 70 and the Fokker 100. For this all tooling for these airplanes was bought from Fokker during the bankruptcy period. Later on the decision was made to make several improvements to the airframe. This resulted in the Fokker 120NG which was further stretched to the Fokker 130NG due to altered market demands. The Fokker 130NG would be able to carry 130 to 138 passengers. It would get a new interior, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USAir
US Airways was a major airline in the United States. It was originally founded in Pittsburgh as a mail delivery airline called All American Aviation, which soon became a commercial passenger airline. In 1953, it was renamed Allegheny Airlines and operated under that name for a quarter-century. In October 1979, after the passage of the Airline Deregulation Act, Allegheny Airlines changed its name to USAir. A decade later it had acquired Piedmont Airlines and Pacific Southwest Airlines (PSA), and was one of the U.S.'s seven transcontinental legacy carriers. In 1997, it rebranded as US Airways. The airline had an extensive international and domestic network, with 193 destinations in 24 countries in North America, South America, Europe, and the Middle East. The airline was a member of the Star Alliance, before becoming an affiliate member of Oneworld in March 2014. US Airways had 343 mainline jets, as well as 278 regional jet and turboprops flown by contract and subsidiary airl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
