WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Hawker 4000
The Hawker 4000, originally known as the Hawker Horizon, is a super-midsize business jet developed by Hawker Beechcraft (formerly Raytheon Aircraft Company). Development Raytheon announced a new business jet in November 1996 as a larger aircraft than the existing Hawker 1000 that formed the top of Raytheon's jet range. The design, then known as the Hawker Horizon, was intended to fly in 1999, with certification and initial customer deliveries planned for 2001.Jerram 2004, p. 31. The first prototype made its maiden flight on August 11, 2001,Jerram 2004, p. 33. with the second prototype and third prototypes making their maiden flights on May 10 and July 31, 2002.Jerram 2004, p. 35.

Reduced Vertical Separation Minima
Reduced vertical separation minimum (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft). Expressed in the International System of Units (SI), it is the reduction, from 600 m to 300 m, of required vertical separation of aircraft between altitudes 8,850 and 12,500 m. This reduction in vertical separation minimum therefore increases the number of aircraft that can fly in a particular volume of controlled airspace. Historical background In 1958 the standard vertical separation of aircraft in controlled airspace was set at 1,000 feet from ground level or sea level to flight level 290, and at 2,000 feet above flight level 290. The larger minimum separations at higher altitudes was necessary because the accuracy of altimeters, used to determine altitude by measuring air pressure, decreases with height. Efforts to ...

Citation Hemisphere
The Cessna Citation Hemisphere was a business jet project by Cessna. Announced in November 2015, it was then expected to fly in 2019 but its development was suspended in April 2018 due to a delay in the development of its Safran Silvercrest engines. It was designed for Mach 0.9 and would have a range. Development Announced at the 2015 National Business Aviation Association (NBAA) conference with the widest cabin in its class, it was expected to fly in 2019. Although the Snecma Silvercrest was originally selected, the process was re-opened to the Pratt & Whitney Canada PW800. The Silvercrest with over of thrust was confirmed for the 2016 NBAA Convention, along the selection of Honeywell Primus Epic cockpit and Thales Group fly-by-wire flight control system. The Silvercrest axial-centrifugal high-pressure compressor architecture is common below but rare in its range, and the pressure losses complexity at the final centrifugal stage made it slow to respond to commands in hi ...

Documentation
Documentation is any communicable material that is used to describe, explain or instruct regarding some attributes of an object, system or procedure, such as its parts, assembly, installation, maintenance and use. As a form of knowledge management and knowledge organization, documentation can be provided on paper, online, or on digital or analog media, such as audio tape or CDs. Examples are user guides, white papers, online help, and quick-reference guides. Paper or hard-copy documentation has become less common. Documentation is often distributed via websites, software products, and other online applications. Documentation as a set of instructional materials shouldn't be confused with documentation science, the study of the recording and retrieval of information. Principles for producing documentation While associated ISO standards are not easily available publicly, a guide from other sources for this topic may serve the purpose.,, Documentation development may involve d ...

Flight Simulator
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities. The term "flight simulator" may carry slightly different meaning in general language and technical documents. In past regulations it referred specifically to devices which can closely mimic the behavior of aircraft throughout various procedures and flight conditions. In more recent definitions, this has been named "full flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avionics
Avionics (a blend word, blend of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case ...

Flight-test
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or atmospheric testing of launch vehicles and reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any design problems and then 2) verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a new aircraft, launch vehicle, or reusable spacecraft. Therefore, the duration of a particular flight test program c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
