Citation I
The Cessna 500 Citation I is a small business jet produced by Cessna, the basis of the Citation family. The Fanjet 500 prototype was announced in October 1968, first flew on September 15, 1969, and was certified as the 500 Citation on September 9, 1971. It was upgraded in 1976 as the ''Citation I'', and the 501 Citation I/SP single-pilot variant was introduced in 1977. Production ended in 1985 with 689 of all variants produced. The straight wing jet is powered by JT15D turbofans. The aircraft was developed into the Citation II. Development In the early 1960s, the three major American general aviation aircraft manufacturers—Beechcraft, Cessna and Piper–faced a competitive challenge in the form of two newly-developed light business jets, the Learjet 23 and the Aero Commander 1121 Jet Commander, which were much less expensive to buy and operate than previous business jets such as the North American Sabreliner and Hawker Siddeley HS.125. Previous efforts by Beechcraft and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Wikimedia project, 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 Magazine, 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 organization ...

North American Sabreliner
The North American Sabreliner, later sold as the Rockwell Sabreliner, is an American mid-sized business jet developed by North American Aviation. It was offered to the United States Air Force (USAF) in response to its Utility Trainer Experimental (UTX) program. It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter. Military variants, designated T-39 Sabreliner, were used by the USAF, United States Navy (USN), and United States Marine Corps (USMC) after the USAF placed an initial order in 1959.North American T-39A Sabreliner ". |
Citation V
The Cessna Citation V is a business jet built by Cessna. A stretched version of the Citation S/II, a Model 560 prototype flew in August 1987, it was certified on December 9, 1988, and delivered from April 1989; were delivered until 2011. The upgraded Citation Ultra was announced in September 1993, the Citation Encore upgraded with PW535 turbofans was announced in 1998, before the improved Encore+. Its US military designation is UC-35 as an executive transport and OT-47B as a drug interdiction reconnaissance aircraft. Design and development The Citation V (Model 560) is a development of the Citation S/II, retaining the supercritical airfoil and swept wing roots of that aircraft, but with a fuselage stretch and recontoured interior for increased passenger space. The passenger cabin is long, wide and high with a dropped aisle, has seven windows on each side and accommodates a four-seat club plus three chairs and a closed, belted lavatory. Maximum seating capacity is eleven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Pilot
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. History The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female aviator. These terms were used more in the ...

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, acting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
