Airstairs
An airstair is a set of steps built into an aircraft so that passengers may board and alight the aircraft. The stairs are often built into a clamshell-style door on the aircraft. Airstairs eliminate the need for passengers to use a mobile stairway or jetway to board or exit the aircraft, providing more independence from ground services. Some of the earliest aircraft to feature airstairs were the Martin 2-0-2 and Martin 4-0-4. Some models of the Douglas DC-3 were also retrofitted with airstairs. As airport infrastructure has developed, the need for airstairs has decreased, as jetways or mobile stairways are often available. Wide-body aircraft rarely employ airstairs, as the doors are significantly higher above the ground than narrow-body aircraft. One notable exception is the Lockheed L-1011, the only wide-body aircraft to feature full-height airstairs. The only other wide-bodies with airstairs, the VC-25 and the Ilyushin Il-86, have airstairs contained in the cargo hold, wi ...

Boeing 727
The Boeing 727 is an American narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavy 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. The only trijet aircraft to be produced by Boeing, the 727 is powered by Pratt & Whitney JT8D low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct. It shares its six-abreast upper fuselage cross-section and cockpit with the 707. The long 727-100 typically carries 106 passengers in two classes over , or 129 in a single class. Launched in 1965, the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that Decem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilyushin Il-86
The Ilyushin Il-86 (russian: Илью́шин Ил-86; NATO reporting name: Camber) is a short- to medium-range wide-body jet airliner that served as the USSR's first wide-bodied aircraft. Designed and tested by the Ilyushin design bureau in the 1970s, it was certified by the Soviet aircraft industry, manufactured and marketed by the USSR. Developed during the rule of Leonid Brezhnev, the Il-86 was marked by the economic and technological stagnation of the era: it used engines more typical of the late 1960s, spent a decade in development, and failed to enter service in time for the Moscow Olympics, as was originally intended. The type was used by Aeroflot and successor post-Soviet airlines and only three of the total 106 constructed were exported. At the beginning of 2012, only four Il-86s remained in service, all with the Russian Air Force. By the end of 2020 the number in active service was reduced to three.

Aircraft Ground Handling
In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually) parked at a Gate (airport), terminal gate of an airport. Overview Many airlines subcontract ground handling to airports, handling agents or even to another airline. According to the International Air Transport Association (IATA), conservative estimates indicate airlines outsource more than 50 per cent of the ground handling that takes place at the world's airports. Ground handling addresses the many service requirements of an airliner between the time it arrives at a terminal gate and the time it departs on its next flight. Speed, efficiency, and accuracy are important in ground handling services in order to minimize the turnaround time (the time during which the aircraft must remain parked at the gate). Faster turnarounds for lower ground times are correlated to better profits. Airlines with less-frequent service or fewer resources at a particular l ...

McDonnell Douglas DC-9
The McDonnell Douglas DC-9 is an American five-abreast single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced by the developer company as the Douglas DC-9 until August 1967 and then by McDonnell Douglas. After introducing its heavy DC-8 in 1959, Douglas approved the smaller, all-new DC-9 for shorter flights on April 8, 1963. The DC-9-10 first flew on February 25, 1965, and gained its type certificate on November 23, to enter service with Delta Air Lines on December 8. The aircraft has two rear-mounted Pratt & Whitney JT8D low-bypass turbofans under a T-tail for a cleaner wing aerodynamic, a two-person flight deck and built-in airstairs. The Series 10 are 104 ft (32 m) long for typically 90 coach seats. The Series 30, stretched by 15 ft (4.5 m) to seat 115 in economy, has a larger wing and more powerful engines for a higher maximum takeoff weight (MTOW); it first flew in August 1966 and entered service in February 1967.

Yakovlev Yak-42
The Yakovlev Yak-42 (russian: Яковлев Як-42; NATO reporting name: "Clobber") is a 100/120-seat three-engined mid-range passenger jet developed in the mid 1970s to replace the technically obsolete Tupolev Tu-134. It was the first airliner produced in the Soviet Union to be powered by modern high-bypass turbofan engines.Gunston, 1997 Development In 1972, the Yakovlev design bureau started work on a short- to medium-range airliner capable of carrying 100–120 passengers. It was intended to be a replacement for the Tupolev Tu-134 jet as well as the Ilyushin Il-18, Antonov An-24 and An-26 turboprop airliners. While the new airliner was required to operate out of relatively small airfields while maintaining good economy, as many Soviet airports had been upgraded to accommodate more advanced aircraft, it did not have to have the same ability to operate from grass strips as Yakovlev's smaller Yak-40. The requirement resulted in the largest, heaviest and most powerful airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas MD-80
The McDonnell Douglas MD-80 is a series of five-abreast single-aisle airliners developed by McDonnell Douglas. It was produced by the developer company until August 1997 and then by Boeing Commercial Airplanes. The MD-80 was the second generation of the DC-9 family, originally designated as the DC-9-80 (DC-9 Series 80) and later stylized as the DC-9 Super 80 (short ''Super 80''). Stretched, enlarged wing and powered by higher bypass Pratt & Whitney JT8D-200 engines, the aircraft program was launched in October 1977. The MD-80 made its first flight on October 18, 1979 as the Super 80 and was certified on August 25, 1980. The first airliner was delivered to launch customer Swissair on September 13, 1980, which introduced it into commercial service on October 10, 1980. Keeping the fuselage cross-section, longer variants are stretched by 14 ft (4.3 m) from the DC-9-50 and have a 28% larger wing. The larger variants (MD-81/82/83/88) are 148 ft (45.1 m) long to seat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas MD-90
The McDonnell Douglas (later Boeing) MD-90 is an American five-abreast single-aisle airliner developed by McDonnell Douglas from its successful model MD-80. The airliner was produced by the developer company until 1997 and then by Boeing Commercial Airplanes. It was a stretched derivative of the MD-80 and thus the third generation of the DC-9 family. After the more fuel-efficient IAE V2500 high-bypass turbofan was selected, Delta Air Lines became the launch customer on November 14, 1989. The MD-90 first flew on February 22, 1993, and the first delivery was in February 1995 to Delta. The MD-90 competed with the Airbus A320ceo family and the Boeing 737 Next Generation. Its 5 ft (1.4 m) longer fuselage seats 153 passengers in a mixed configuration over up to 2,455 nmi (4,547 km), making it the largest member of the DC-9 family. It kept the MD-88's electronic flight instrument system (EFIS). The shrunken derivative of MD-80 or shorter variant of MD-90, originally m ...

BAC 1-11
The BAC One-Eleven (or BAC-111/BAC 1-11) was an early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to its launch customer on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom and between 1982 and 1989 in Romania where nine Rombac One-Eleven were licence-built by Romaero. The short haul, narrowbody aircraft was powered by aft-mounted Rolls-Royce Spey low-bypass turbofans, a configuration similar to the earlier Sud Aviation Caravelle and later Douglas DC-9. It also competed with early Boeing 737 variants and was used by several US carriers, as well as multiple British, overseas and European airli ...

Yakovlev Yak-40
The Yakovlev Yak-40 (russian: Яковлев Як-40; NATO reporting name: Codling) is a regional jet designed by Yakovlev. The trijet's maiden flight was in 1966, and it was in production from 1967 to 1981. Introduced in September 1968, the Yak-40 has been exported since 1970. Development By the early 1960s, Soviet international and internal trunk routes were served by Aeroflot, the state airline, using jet or turboprop powered airliners, but their local services, many of which operated from grass airfields, were served by obsolete piston-engine aircraft such as the Ilyushin Il-12, Il-14 and Lisunov Li-2.Stroud 1968, p. 269–270. Aeroflot wanted to replace these elderly airliners with a turbine-powered aircraft, with the Yakovlev design bureau being assigned to design it. High speed was not required, but it would have to be able to operate safely and reliably out of poorly equipped airports with short (less than 700 m or 2,300 ft) unpaved runways in poor weather.Gunsto ...

VFW-Fokker 614
The VFW-Fokker 614 (also VFW 614) was a twin-engined jetliner designed and constructed by West German aviation company VFW-Fokker. It is the first jet-powered passenger liner to be developed and produced in West Germany (the East German Baade 152 being the first German jet airliner), as well as the first German-built civil aircraft to have been manufactured for a decade.Mendenhall 2005, p. 326. The VFW 614 was originally proposed during the early 1960s as the E.614, which was a concept for a 36–40 seat aircraft by a consortium of West German aircraft companies, who were soon re-organised into Vereinigte Flugtechnische Werke (VFW). Originally intended as a Douglas DC-3 replacement, its most distinctive feature was that its engines were mounted in pods on pylons above the wing. The VFW 614 was produced in small numbers during the early- to mid-1970s by VFW-Fokker, a company resulting from a merger between VFW and the Dutch aircraft company Fokker. The program was cancelled in 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker F-28
The Fokker F28 Fellowship is a twin-engined, short-range jet airliner designed and built by Dutch aircraft manufacturer Fokker. Following the Fokker F27 Friendship, an early and commercially successful turboprop-powered regional airliner, Fokker decided to embark on developing a new turbojet-powered commuter aircraft that would build upon its experiences with the F27. During the design phase, a high level of attention was paid to market research and operator concerns; amongst other changes made, the prospective jetliner was increased in size, changing its maximum seating capacity from 50 to 65 passengers. During April 1962, Fokker announced the formal launch of the F28 Fellowship. On 9 May 1967, the prototype F28-1000 conducted its maiden flight. Type certification was achieved on 24 February 1969, and the first revenue-earning flight by Braathens was performed on 28 March 1969. Following its entry to service, Fokker developed multiple variants of the F28; one model, the F28-2000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing VC-25
The Boeing VC-25 is a military version of the Boeing 747 airliner, modified for presidential transport and commonly operated by the United States Air Force (USAF) as ''Air Force One'', the call sign of any U.S. Air Force aircraft carrying the president of the United States. Only two examples of this aircraft type are in service; they are highly modified Boeing 747-200Bs, designated VC-25A and having tail numbers 28000 and 29000. Although technically the ''Air Force One'' designation applies to the aircraft only while the president is on board, the term is commonly used to refer to the VC-25 in general. The two aircraft often operate in conjunction with ''Marine One'' helicopters, which ferry the president to airports whenever a vehicle motorcade would be inappropriate. Two new aircraft, designated VC-25B and based on the Boeing 747-8, have been ordered by the USAF to replace the aging VC-25As. Development By 1985, the pair of Boeing 707-based VC-137s used as the presidential ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
