The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the A300, its first airliner, and developed the A340 quadjet in parallel with the A330 twinjet. In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France. The larger A340-500/600 were launched on 8 December 1997; the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002.
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express parcel deliveries, and some are used by public bodies, government officials, VIPs, or even the armed forces.
A regional airliner or a 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.
The Ilyushin Il-96 is a Russian four-engined jet long-haul wide-body airliner designed by Ilyushin in the former Soviet Union and manufactured by the Voronezh Aircraft Production Association in Russia. It is powered by four high-bypass Aviadvigatel PS-90 two-shaft turbofan engines.
The Sukhoi Superjet 100 or SSJ100 is a regional jet designed by Russian aircraft company Sukhoi Civil Aircraft, a division of the United Aircraft Corporation. With development starting in 2000, it made its maiden flight on 19 May 2008 and its first commercial flight on 21 April 2011 with Armavia.
The Pilatus PC-12 is a pressurized, single-engined, turboprop aircraft manufactured by Pilatus Aircraft of Stans, Switzerland since 1991. It was designed as a high-performance utility aircraft that incorporates a large aft cargo door in addition to the main passenger door. Due to its efficient, high-utility design, the PC-12 is used by a large variety of operators. The main use for the aircraft is corporate transportation, but it is also used by fractional and small regional airlines, air-ambulance operators, and many government agencies, such as police departments and armed forces. The PC-12 is successful with 2,000 deliveries made as of May 2023.

The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines and the social and cultural changes fostered by commercial jet travel.
The McDonnell Douglas DC-9 is an American five-abreast, single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced as the Douglas DC-9 prior to August 1967, after which point the company had merged with McDonnell Aircraft to become McDonnell Douglas. Following the introduction of its first jetliner, the high-capacity DC-8, in 1959, Douglas was interested in producing an aircraft suited to smaller routes. As early as 1958, design studies were conducted; approval for the DC-9, a smaller all-new jetliner, came 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 Dornier 328 is a turboprop-powered commuter airliner. Initially produced by Dornier Luftfahrt GmbH, the firm was acquired in 1996 by Fairchild Aircraft. The resulting firm, named Fairchild-Dornier, manufactured the 328 family in Oberpfaffenhofen, Germany, conducted sales from San Antonio, Texas, United States, and supported the product line from both locations. A jet-powered version of the aircraft, the Fairchild Dornier 328JET, was also produced.
The Pakistan Aeronautical Complex (PAC) is a major defense contractor and an aerospace manufacturer that is headquartered in Kamra, Punjab, Pakistan.
A regional jet (RJ) is a jet-powered regional airliner with fewer than 100 seats. The first one was the Sud-Aviation Caravelle in 1959, followed by the widespread Yakovlev Yak-40, Fokker F-28, and BAe 146. The 1990s saw the emergence of the most widespread Canadair Regional Jet and its Embraer Regional Jet counterpart, then the larger Embraer E-Jet and multiple competing projects. In the US, they are limited in size by scope clauses.

Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.
The Cessna CitationJet/CJ/M2 are a series of light business jets built by Cessna, and are part of the Citation family. Launched in October 1989, the first flight of the Model 525 was on April 29, 1991. Federal Aviation Administration (FAA) certification was awarded on October 16, 1992, and the first aircraft was delivered on March 30, 1993. The CJ series are powered by two Williams FJ44 engines; the design uses the Citation II's forward fuselage with a new carry-through section wing and a T-tail. The original CitationJet model has been updated into the CJ1/CJ1+/M2 variants; additionally, the CJ1 was stretched into the CJ2/CJ2+ which was built between 2000 and 2016. The design was then further developed into the CJ3/CJ3+, built from December 2004 to present, and finally into the CJ4 which has been built since 2010. By June 2017, 2,000 of all variants had been delivered.
The Hawker Siddeley HS-121 Trident is a British airliner produced by Hawker Siddeley. In 1957, de Havilland proposed its DH.121 trijet design to a British European Airways (BEA) request. By 1960, de Havilland had been acquired by Hawker Siddeley. The Trident's maiden flight happened on 9 January 1962, and it was introduced on 1 April 1964, two months after its main competitor, the Boeing 727. By the end of the programme in 1978, 117 Tridents had been produced. The Trident was withdrawn from service in 1995.
The Bombardier CRJ100 and CRJ200 is a regional jet designed and manufactured by Bombardier Aerospace between 1991 and 2006, the first of the Bombardier CRJ family.
The Bombardier CRJ550, CRJ700, CRJ705, CRJ900, and CRJ1000 are a family of regional jet airliners that were designed and manufactured by Canadian transportation conglomerate Bombardier between 1999 and 2020. Their design was derived from the smaller CRJ100 and 200 airliners, the other members of the Bombardier CRJ aircraft family. The CRJ program was acquired by the Japanese corporation Mitsubishi Heavy Industries in 2020, which ended production of the aircraft.
The Embraer E-Jet E2 family are medium-range twinjet airliners designed and produced by the Brazilian aircraft manufacturer Embraer. It was developed as a successor to the original E-Jet family.
A four-engined jet, sometimes called a quadjet, is a jet aircraft powered by four engines. The presence of four engines offers increased power, allowing such aircraft to be used as airliners, freighters, and military aircraft. Many of the first purpose-built jet airliners had four engines, among which stands the De Havilland Comet, the world's first commercial jetliner. In the decades following their introduction, their use has gradually declined due to a variety of factors, including the approval of twin-engine jets to fly farther from diversion airports as reliability increased, and an increased emphasis on fuel efficiency.
