Saab 2000
The Saab 2000 is a twin-engined high-speed turboprop airliner built by Swedish aircraft manufacturer Saab. It is designed to carry 50–58 passengers and able to cruise at a maximum speed of . Production took place in Linköping, Sweden. It first flew in March 1992 and was certified in 1994. The last aircraft was delivered in April 1999, a total of 63 aircraft were built. As of October 2024, a total of 31 Saab 2000s are either in airline or military service. Development and design In the 1980s, Saab decided to build a fuselage-stretched derivative of its successful Saab 340 twin-turboprop regional airliner. The new aircraft was planned to meet a perceived demand for a high-speed 50-seat turboprop with good climb performance which could operate over short- and medium-range routes with similar block times to jet aircraft while retaining the efficiency provided by turboprop engines. The new airliner, named the Saab 2000, was formally launched in May 1989, with Saab already hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regional Airliner
A regional airliner, commuter airliner or feeder liner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feeder liner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines. Examples included the De Havilland Dragon Rapide biplane and the Douglas DC-3s, in large surplus after the war, which the a ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine. The aircraft never flew, but a patent was filed for routing exhaust gases into the duct to augment thrust. * 1914: Auguste Rateau suggests using exhaust-powered compressor – a turbocharger – to improve high-altitude performance; not accepted after the ...

Allison GMA 2100
The Rolls-Royce AE 2100 is a turboprop developed by Allison Engine Company, now part of Rolls-Royce North America. The engine was originally known as the GMA 2100, when Allison was a division of former corporate parent General Motors. Development On July 11, 1989, Saab-Scania A.B. selected the GMA 2100 to power its new Saab 2000, a 50-seat stretch of the Saab 340 turboprop, in a US$500 million deal. In July 1990, Industri Pesawat Terbang Nusantara (IPTN) of Indonesia picked the GMA 2100 as the engine for the twin-engine N-250 regional airliner. Flight testing with a Dowty R373 propeller on a Lockheed P-3 Orion testbed aircraft began on August 23, 1990, and finished after over 50 hours of flight and ground testing. The GMA 2100D3 became the powerplant for the Lockheed Martin C-130J Super Hercules.

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Aviation Authorities
The Joint Aviation Authorities (JAA) was an associated body of the European Civil Aviation Conference representing the civil aviation regulatory authorities of a number of European States who had agreed to co-operate in developing and implementing common safety regulatory standards and procedures. It was not a regulatory body, regulation being achieved through the member authorities. It was in existence from 1970 until disbanded in 2009. Its headquarters were located in Hoofddorp near Schiphol airport in Netherlands. JAA issued the Joint Aviation Requirements (JAR), intended to establish minimum requirements for air safety. In implementing the so-called FUJA Report, JAA entered into a new phase as of 1 January 2007. In this new phase the former "JAA" became "JAA T" (Transition). JAA T consisted of a Liaison Office (JAA LO) and a Training Office (JAA TO). The offices of JAA LO were located in the premises of the European Union Aviation Safety Agency (EA ...
