58-571: The AIS Group also includes AIS Technics which provides technical support and the AIS Flight Academy. The AIS Flight Academy is a flight school located at Lelystad Airport and is engaged in the integrated training of commercial pilots (ATPL(A)). In addition, to the flight school, AIS has a so-called 'type training' for the Jetstream 31 /32. AIS's Jetstream full flight simulator is the only approved simulator for this aircraft type in

116-438: A Light Aircraft Pilot Licence (LAPL), but this cannot be used internationally. Separate licences are required for different aircraft categories , for example helicopters and aeroplanes . A type rating , also known as an endorsement, is the process undertaken by a pilot to update their license to allow them to fly a different type of aircraft . A class rating covers multiple aircraft. An instrument rating allows

174-399: A basic plane and must then be completed by the builder. Few companies produce planes on a large scale. However, the production of a plane for one company is a process that actually involves dozens, or even hundreds, of other companies and plants, that produce the parts that go into the plane. For example, one company can be responsible for the production of the landing gear, while another one

232-578: A combustion chamber or a solid fuel with oxidizer may burn in the fuel chamber. Whether liquid or solid-fueled, the hot gas is accelerated through a nozzle. In World War II , the Germans deployed the Me 163 Komet rocket-powered aircraft . The first plane to break the sound barrier in level flight was a rocket plane – the Bell X-1 in 1948. The North American X-15 broke many speed and altitude records in

290-435: A craft that weighed 3.5 tons, with a 110-foot (34 m) wingspan that was powered by two 360-horsepower (270 kW) steam engines driving two propellers. In 1894, his machine was tested with overhead rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable and it is presumed that Maxim realized this because he subsequently abandoned work on it. Between 1867 and 1896,

348-781: A first flight. The flight tests continue until the aircraft has fulfilled all the requirements. Then, the governing public agency of aviation of the country authorizes the company to begin production. In the United States, this agency is the Federal Aviation Administration (FAA). In the European Union, European Aviation Safety Agency (EASA); in the United Kingdom it is the Civil Aviation Authority (CAA). In Canada,

406-468: A form of roll control supplied either by wing warping or by ailerons and controlled by its pilot with a joystick and rudder bar. It was an important predecessor of his later Blériot XI Channel -crossing aircraft of the summer of 1909. World War I served as a testbed for the use of the airplane as a weapon. Airplanes demonstrated their potential as mobile observation platforms, then proved themselves to be machines of war capable of causing casualties to

464-412: A frame and made rigid by the lift forces exerted by the airflow over them. Larger aircraft have rigid wing surfaces which provide additional strength. Whether flexible or rigid, most wings have a strong frame to give them their shape and to transfer lift from the wing surface to the rest of the aircraft. The main structural elements are one or more spars running from root to tip, and many ribs running from

522-414: A jet-powered aircraft with a speed of Mach 9.7, nearly 12,100 kilometers per hour (7,500 mph). Whereas jet aircraft use the atmosphere both as a source of oxidant and of mass to accelerate reactively behind the aircraft, rocket aircraft carry the oxidizer on board and accelerate the burned fuel and oxidizer backwards as the sole source of mass for reaction. Liquid fuel and oxidizer may be pumped into

580-462: A pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones. The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight". They built on the works of George Cayley dating from 1799, when he set forth the concept of the modern airplane (and later built and flew models and successful passenger-carrying gliders ) and

638-401: A pilot to fly under instrument flight rules (IFR). A night rating allows a pilot to fly at night (that is, outside of Civil twilight ). Aeroplanes An airplane ( North American English ) or aeroplane ( British English ), informally plane , is a fixed-wing aircraft that is propelled forward by thrust from a jet engine , propeller , or rocket engine . Airplanes come in

696-416: A propeller creates is determined, in part, by its disk area—the area through which the blades rotate. The limitation on blade speed is the speed of sound ; as when the blade tip exceeds the speed of sound, shock waves decrease propeller efficiency. The rpm required to generate a given tip speed is inversely proportional to the diameter of the propeller. The upper design speed limit for propeller-driven aircraft

754-477: A shaft through a reduction gearing to the propeller. The propelling nozzle provides a relatively small proportion of the thrust generated by a turboprop. An electric aircraft runs on electric motors with electricity coming from fuel cells , solar cells , ultracapacitors , power beaming , or batteries . Currently, flying electric aircraft are mostly experimental prototypes, including manned and unmanned aerial vehicles , but there are some production models on

812-426: A single wing plane, a biplane has two stacked one above the other, a tandem wing has two placed one behind the other. When the available engine power increased during the 1920s and 30s and bracing was no longer needed, the unbraced or cantilever monoplane became the most common form of powered type. The wing planform is the shape when seen from above. To be aerodynamically efficient, a wing should be straight with

870-435: A small and simple engine for high-speed use, such as with missiles. Ramjets require forward motion before they can generate thrust and so are often used in conjunction with other forms of propulsion, or with an external means of achieving sufficient speed. The Lockheed D-21 was a Mach 3+ ramjet-powered reconnaissance drone that was launched from a parent aircraft . A ramjet uses the vehicle's forward motion to force air through

928-447: A variety of sizes, shapes, and wing configurations . The broad spectrum of uses for airplanes includes recreation , transportation of goods and people, military , and research . Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne - kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by

986-486: Is Mach 0.6. Aircraft designed to go faster than that employ jet engines. Reciprocating engines in aircraft have three main variants, radial , in-line and flat or horizontally opposed engine . The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel and was commonly used for aircraft engines before gas turbine engines became predominant. An inline engine

1044-421: Is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, but rarely more than six, and may be water-cooled. A flat engine is an internal combustion engine with horizontally-opposed cylinders. A turboprop gas turbine engine consists of an intake, compressor, combustor, turbine, and a propelling nozzle, which provide power from

1102-420: Is responsible for the radar. The production of such parts is not limited to the same city or country; in the case of large plane manufacturing companies, such parts can come from all over the world. The parts are sent to the main plant of the plane company, where the production line is located. In the case of large planes, production lines dedicated to the assembly of certain parts of the plane can exist, especially

1160-736: Is the Royal Air Force 's (RAF's) Central Flying School formed in May 1912 at Upavon , United Kingdom . The oldest civil flight school still active in the world is based in Germany at the Wasserkuppe . It was founded as "Mertens Fliegerschule", and is currently named "Fliegerschule Wasserkuppe". Pilots must first gain their Private Pilot Licence (PPL). They can then progress to a Commercial Pilot Licence (CPL), and finally an Airline Transport Pilot Licence (ATPL). Some countries have

1218-461: Is the acquisition and honing of basic airmanship skills. Flight training can be conducted under a structured accredited syllabus with a flight instructor at a flight school or as private lessons with no syllabus with a flight instructor as long as all experience requirements for the desired pilot certificate/license are met. Typically flight training consists of a combination of two parts: Although there are various types of aircraft, many of

1276-404: The Éole . It was a bat-like design run by a lightweight steam engine of his own invention, with four cylinders developing 20 horsepower (15  kW ), driving a four-blade propeller . The engine weighed no more than 4 kilograms per kilowatt (6.6 lb/hp). The wings had a span of 14 m (46 ft). All-up weight was 300 kilograms (660 lb). On 9 October 1890, Ader attempted to fly

1334-559: The Greek legend of Icarus and Daedalus , and the Vimana in ancient Indian epics . Around 400 BC in Greece , Archytas was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have flown some 200 m (660 ft). This machine may have been suspended for its flight. Some of

1392-593: The Münster-Osnabrück route to Copenhagen (via Groningen ). As of October 2021, AIS Airlines only operated the Torsby route to Stockholm Arlanda via Hagfors on behalf of Amapola Flyg. In 2023 Amapola Flyg lost these route contracts. Instead AIS Airlines won contracts on Denmark routes in 2023. AIS Airlines serves the following scheduled routes: As of January 2024, the AIS Airlines fleet consists of

1450-416: The center of mass and the center of pressure of flying birds. In 1799, George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris made

1508-638: The de Havilland Comet , was introduced in 1952. The Boeing 707 , the first widely successful commercial jet, was in commercial service for more than 60 years, from 1958 to 2019. First attested in English in the late 19th century (prior to the first sustained powered flight), the word airplane , like aeroplane , derives from the French aéroplane , which comes from the Greek ἀήρ ( aēr ), "air" and either Latin planus , "level", or Greek πλάνος ( planos ), "wandering". " Aéroplane " originally referred just to

1566-494: The Éole . Aviation historians give credit to this effort as a powered take-off and uncontrolled hop of approximately 50 m (160 ft) at a height of approximately 200 mm (7.9 in). Ader's two subsequent machines were not documented to have achieved flight. The American Wright brothers 's flights in 1903 are recognized by the Fédération Aéronautique Internationale (FAI),

1624-605: The 1920s and 30s, wings could be made heavy and strong enough that bracing was not needed any more. This type of unbraced wing is called a cantilever wing. The number and shape of the wings varies widely on different types. A given wing plane may be full-span or divided by a central fuselage into port (left) and starboard (right) wings. Occasionally, even more wings have been used, with the three-winged triplane achieving some fame in WWI. The four-winged quadruplane and other multiplane designs have had little success. A monoplane has

1682-462: The 1960s and pioneered engineering concepts for later aircraft and spacecraft. Military transport aircraft may employ rocket-assisted take offs for short-field situations. Otherwise, rocket aircraft include spaceplanes , like SpaceShipTwo , for travel beyond the Earth's atmosphere and sport aircraft developed for the short-lived Rocket Racing League . Most airplanes are constructed by companies with

1740-622: The Concorde to remove it from service. An aircraft propeller , or airscrew , converts rotary motion from an engine or other power source, into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached two or more radial airfoil -section blades such that the whole assembly rotates about a longitudinal axis. Three types of aviation engines used to power propellers include reciprocating engines (or piston engines), gas turbines , and electric motors . The amount of thrust

1798-501: The German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights. Lilienthal's work led to him developing the concept of the modern wing, his flight attempts in 1891 are seen as the beginning of human flight, the " Lilienthal Normalsegelapparat " is considered to be the first airplane in series production and his work heavily inspired

1856-456: The Wright brothers. In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted. Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft. The Frenchman Clement Ader constructed his first of three flying machines in 1886,

1914-485: The air entering the engine must be decelerated to a subsonic speed and then re-accelerated back to supersonic speeds after combustion. An afterburner may be used on combat aircraft to increase power for short periods of time by injecting fuel directly into the hot exhaust gases. Many jet aircraft also use thrust reversers to slow down after landing. A ramjet is a form of jet engine that contains no major moving parts and can be particularly useful in applications requiring

1972-437: The behavior of the aircraft. Computers are used by companies to draw, plan and do initial simulations of the aircraft. Small models and mockups of all or certain parts of the plane are then tested in wind tunnels to verify its aerodynamics. When the design has passed through these processes, the company constructs a limited number of prototypes for testing on the ground. Representatives from an aviation governing agency often make

2030-906: The case of international sales, a license from the public agency of aviation or transport of the country where the aircraft is to be used is also necessary. For example, airplanes made by the European company, Airbus , need to be certified by the FAA to be flown in the United States, and airplanes made by U.S.-based Boeing need to be approved by the EASA to be flown in the European Union. Regulations have resulted in reduced noise from aircraft engines in response to increased noise pollution from growth in air traffic over urban areas near airports. Small planes can be designed and constructed by amateurs as homebuilts. Other homebuilt aircraft can be assembled using pre-manufactured kits of parts that can be assembled into

2088-426: The combustion air, prior to the introduction and ignition of fuel. Rocket motors provide thrust by burning a fuel with an oxidizer and expelling gas through a nozzle. Most jet aircraft use turbofan jet engines, which employ a gas turbine to drive a ducted fan, which accelerates air around the turbine to provide thrust in addition to that which is accelerated through the turbine. The ratio of air passing around

2146-471: The earliest recorded attempts with gliders were those by the 9th-century Andalusian and Arabic-language poet Abbas ibn Firnas and the 11th-century English monk Eilmer of Malmesbury ; both experiments injured their pilots. Leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds (1502), noting for the first time the distinction between

2204-479: The end of WWII all-metal aircraft were common. In modern times, increasing use of composite materials has been made. Typical structural parts include: The wings of a fixed-wing aircraft are static planes extending either side of the aircraft. When the aircraft travels forwards, air flows over the wings, which are shaped to create lift. This shape is called an airfoil and is shaped like a bird's wing. Airplanes have flexible wing surfaces which are stretched across

2262-537: The enemy. The earliest known aerial victory with a synchronized machine gun-armed fighter aircraft occurred in 1915, by German Luftstreitkräfte Leutnant Kurt Wintgens . Fighter aces appeared; the greatest (by number of Aerial Combat victories) was Manfred von Richthofen , also known as the Red Baron. Following WWI, aircraft technology continued to develop. Alcock and Brown crossed the Atlantic non-stop for

2320-426: The engine without resorting to turbines or vanes. Fuel is added and ignited, which heats and expands the air to provide thrust. A scramjet is a specialized ramjet that uses internal supersonic airflow to compress, combine with fuel, combust and accelerate the exhaust to provide thrust. The engine operates at supersonic speeds only. The NASA X-43 , an experimental unmanned scramjet, set a world speed record in 2004 for

2378-535: The first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. Then the Russian Alexander F. Mozhaisky also made some innovative designs. In 1883, the American John J. Montgomery made a controlled flight in a glider. Other aviators who made similar flights at that time were Otto Lilienthal , Percy Pilcher , and Octave Chanute . Sir Hiram Maxim built

2436-628: The first time in 1919. The first international commercial flights took place between the United States and Canada in 1919. Airplanes had a presence in all the major battles of World War II . They were an essential component of the military strategies of the period, such as the German Blitzkrieg , The Battle of Britain , and the American and Japanese aircraft carrier campaigns of the Pacific War . The first practical jet aircraft

2494-428: The following aircraft: AIS Development is concentrating on new developments in electric flying. AIS is in the process of developing an electric type of Jetstream. The Jetstream is one of the first to be developed in terms of size and possibilities. Flight school Flight training is a course of study used when learning to pilot an aircraft . The overall purpose of primary and intermediate flight training

2552-399: The leading (front) to the trailing (rear) edge. Early airplane engines had little power, and lightness was very important. Also, early airfoil sections were very thin, and could not have a strong frame installed within. So, until the 1930s, most wings were too lightweight to have enough strength, and external bracing struts and wires were added. When the available engine power increased during

2610-422: The manufacturer or the customer. The structural parts of a fixed-wing aircraft are called the airframe. The parts present can vary according to the aircraft's type and purpose. Early types were usually made of wood with fabric wing surfaces, When engines became available for powered flight around a hundred years ago, their mounts were made of metal. Then as speeds increased more and more parts became metal until by

2668-440: The market. Jet aircraft are propelled by jet engines , which are used because the aerodynamic limitations of propellers do not apply to jet propulsion. These engines are much more powerful than a reciprocating engine for a given size or weight and are comparatively quiet and work well at higher altitude. Variants of the jet engine include the ramjet and the scramjet , which rely on high airspeed and intake geometry to compress

2726-405: The objective of producing them in quantity for customers. The design and planning process, including safety tests, can last up to four years for small turboprops or longer for larger planes. During this process, the objectives and design specifications of the aircraft are established. First the construction company uses drawings and equations, simulations, wind tunnel tests and experience to predict

2784-544: The principles of piloting them have common techniques, especially those aircraft which are heavier-than-air types. Flight schools commonly rent aircraft to students and licensed pilots at an hourly rate. Typically, the hourly rate is determined by the aircraft's Hobbs meter or Tach timer , therefore the student is only charged while the aircraft engine is running. Flight instructors can also be scheduled with or without an aircraft for pilot proficiency and recurring training. The oldest flight training school still in existence

2842-586: The public agency in charge and authorizing the mass production of aircraft is Transport Canada's Civil Aviation Authority. When a part or component needs to be joined together by welding for virtually any aerospace or defense application, it must meet the most stringent and specific safety regulations and standards. Nadcap , or the National Aerospace and Defense Contractors Accreditation Program sets global requirements for quality, quality management and quality assurance for aerospace engineering. In

2900-567: The standard-setting and record-keeping body for aeronautics , as "the first sustained and controlled heavier-than-air powered flight". By 1905, the Wright Flyer III was capable of fully controllable, stable flight for substantial periods. The Wright brothers credited Otto Lilienthal as a major inspiration for their decision to pursue manned flight. In 1906, the Brazilian Alberto Santos-Dumont made what

2958-408: The turbine to that passing through is called the by-pass ratio . They represent a compromise between turbojet (with no bypass) and turboprop forms of aircraft propulsion (primarily powered with bypass air). Subsonic aircraft, such as airliners, employ high by-pass jet engines for fuel efficiency. Supersonic aircraft , such as jet fighters, use low-bypass turbofans. However at supersonic speeds,

3016-515: The wing, as it is a plane moving through the air. In an example of synecdoche , the word for the wing came to refer to the entire aircraft. In the United States and Canada, the term "airplane" is used for powered fixed-wing aircraft. In the United Kingdom and Ireland and most of the Commonwealth , the term "aeroplane" ( / ˈ ɛər ə p l eɪ n / ) is usually applied to these aircraft. Many stories from antiquity involve flight, such as

3074-408: The wings and the fuselage. When complete, a plane is rigorously inspected to search for imperfections and defects. After approval by inspectors, the plane is put through a series of flight tests to assure that all systems are working correctly and that the plane handles properly. To meet a particular customer need, the airplane may be customised using components or packages of components provided by

3132-581: The work of German pioneer of human aviation Otto Lilienthal , who, between 1867 and 1896, also studied heavier-than-air flight. Lilienthal's flight attempts in 1891 are seen as the beginning of human flight. Following its limited use in World War I , aircraft technology continued to develop. Airplanes had a presence in all the major battles of World War II . The first jet aircraft was the German Heinkel He 178 in 1939. The first jet airliner ,

3190-751: The world. The Group consist of: AIS Airlines, AIS Flight Academy, AIS CAMO, AIS SIM Department and AIS Development. The company started as a flight school and then expanded into the airline business. The airline started an expansion of scheduled routes, mainly within Germany, in 2014, including some formerly served by the now-defunct OLT Express Germany . Flights from Bremen to Luxembourg, Malmö and Nuremberg were announced for autumn 2014, but these plans were later cancelled. By January 2015, AIS Airlines additionally took over some Swedish domestic routes under its own brand, that it formerly operated on behalf of Direktflyg . On February 27, 2020, AIS Airlines discontinued

3248-607: Was claimed to be the first airplane flight unassisted by catapult and set the first world record recognized by the Aéro-Club de France by flying 220 meters (720 ft) in less than 22 seconds. This flight was also certified by the FAI. An early aircraft design that brought together the modern monoplane tractor configuration was the Blériot VIII design of 1908. It had movable tail surfaces controlling both yaw and pitch,

3306-542: Was the German Heinkel He 178 , which was tested in 1939. In 1943, the Messerschmitt Me 262 , the first operational jet fighter aircraft, went into service in the German Luftwaffe . The first jet airliner , the de Havilland Comet , was introduced in 1952. The Boeing 707 , the first widely successful commercial jet, was in commercial service for more than 50 years, from 1958 to 2010. The Boeing 747

3364-529: Was the world's biggest passenger aircraft from 1970 until it was surpassed by the Airbus A380 in 2005. Supersonic airliner flights , including those of the Concorde , have been limited to over-water flight at supersonic speed because of their sonic boom , which is prohibited over most populated land areas. The high cost of operation per passenger-mile and a deadly crash in 2000 induced the operators of
