Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major c ...

Beechcraft 1900
The Beechcraft 1900 is a 19-passenger, pressurized twin-engine turboprop regional airliner manufactured by Beechcraft. It is also used as a freight aircraft and corporate transport, and by several governmental and military organizations. With customers favoring larger regional jets, Raytheon ended production in October 2002. Developed from the Beechcraft Super King Air, the aircraft was designed to carry passengers in all weather conditions from airports with relatively short runways. It is capable of flying in excess of , although few operators use its full-fuel range. In terms of the number of aircraft built and its continued use by many passenger airlines and other users, it is one of the most popular 19-passenger airliners in history. Development The 1900 is Beechcraft's third regional airliner after the Beechcraft Model 18 and Beechcraft Model 99 Airliner. The Beechcraft 1900's design lineage began in 1949 with the Beechcraft Model 50 Twin Bonanza, a 5-passenger, re ...

Regional Airliner
A regional airliner or a feederliner 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. Feederliner, 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: even the De Havilland Dragon Rapide biplane, or the Douglas DC-3s, in large surplus after the war, which the Aircraft manufacturers wante ...

Sikorsky Russky Vityaz
The Sikorsky Russky Vityaz (russian: link=no, Русский витязь), or Russian Knight (S-21), previously known as the Bolshoi Baltisky (russian: link=no, Большой Балтийский) ''(The Great Baltic)'' in its first four-engined version, was the first four-engine aircraft in the world, designed by Igor Sikorsky and built at the Russian Baltic Railroad Car Works (''Russo-Baltiiskyi Vagonnyi Zavod'' or ''R-BVZ'') in Saint Petersburg in early 1913. Development Sikorsky conceived the S-21 design in 1911, when no known aircraft could lift more than . The carrying capacity record belonged to the French pilot Ducis, who had flown with a load of . On hearing about the construction of the ''Russky Vityaz'' in early 1913, the experts and the media around the world were predicting a complete failure. The first aerial test of the ''Russky Vityaz'' on 10 May 1913 was successful. At the time, many people in other parts of the world considered it to be a newspaper hoax, ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger h ...

Narrow-body Aircraft
A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than , allowing at least seven-abreast seating and often more travel classes. Market Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic, McDonnell-Douglas MD-80 and Airbus A320 were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's wide-body aircraft. The re-engined B737 MAX and A320neo jets offer 500 miles more range, allowing them to operate the 3,000 miles transatlantic flights between the eastern U.S. and Western Europe, previously dominated by wide-body aircraft. Norwegian Air Shuttle, JetBlue Airways and TAP Po ...

Sikorsky Ilya Muromets
The Sikorsky ''Ilya Muromets'' (russian: Сикорский Илья Муромец) (Sikorsky S-22, S-23, S-24, S-25, S-26 and S-27) were a class of Russian pre-World War I large four-engine commercial airliners and military heavy bombers used during World War I by the Russian Empire. The aircraft series was named after Ilya Muromets, a hero from Slavic mythology.Lake 2002, p. 31. The series was based on the Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky. The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board. The Ilya Muromets was the world's first multi-engine aircraft in production and at least sixty were built.Sikorsky 1938, p. 96. During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit.Massenkov et al. 1994, p. 23. This heavy bomber was un ...

Airline
An airline is a company that provides air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Czech Republic's Czech Airlines (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has a ...

Airplane
An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, Propeller (aircraft), propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, air transportation, transportation of goods and people, military aviation, military, and Experimental aircraft, research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometersMeasured in RTKs—an RTK is one tonne of revenue freight carried one kilometer. of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be unmanned aerial vehicle, remotely or computer-controlled such as drones. The Wright brothers invented and flew the Wright Flyer, first airplane in 1903, recognized as " ...

Wide-body Aircraft
A wide-body aircraft, also known as a twin-aisle aircraft, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is . In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers. The largest wide-body aircraft are over wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body airliner has a diameter of , with a single aisle, and seats between two and six people abreast. Wide-body aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passenger space in order to insert more seats and increase revenue and profits. Wide-body aircraft are also used for the transport of commercial freight and cargo ...

Flight Length
In aviation, the flight length refers to the distance of a flight. Commercial flights are often categorized into long-, medium- or short-haul by commercial airlines based on flight length, although there is no international standard definition and many airlines use air time or geographic boundaries instead. Route category lengths tend to define short-haul routes as being shorter than , long-haul as being longer than , and medium-haul as being in-between. The related term flight duration is defined as to the amount of time a single flight (segment) is scheduled to take from pushing back at the departure gate to arriving at its destination gate. It is formally defined by ICAO (International Civil Aviation Organization) as "The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight" also referred to colloquially as "chocks to chocks" time. Flight duration is formally measured in hours & min ...
