Subsonic ( or low-speed ) aerodynamics is the study of fluid motion which is everywhere much slower than the speed of sound through the fluid or gas.

The aircraft involved, a Boeing 757-223, was flying American Airlines ' daily scheduled morning transcontinental service from Washington Dulles International Airport, in Dulles, Virginia to Los Angeles International Airport in Los Angeles, California.

Weather systems such as weather radar ( typically Arinc 708 on commercial aircraft ) and lightning detectors are important for aircraft flying at night or in instrument meteorological conditions, where it is not possible for pilots to see the weather ahead.

Meanwhile, flying prototypes of aircraft powered by alternative fuels, such as ethanol, electricity, and even solar energy, are becoming more common and may soon enter the mainstream, at least for light aircraft.

An air show, also " airshow ", Air Fair, or Air Tatoo is an event at which aviators display their flying skills and the capabilities of their aircraft to spectators in aerobatics.

When surface to air missiles became capable of hitting high flying aircraft bombers, bombers used flight at low altitude to evade radar detection.

As of late 2002, the Navy had reportedly become responsible for flying all aircraft with the rivalry having subsided between the two branches of the armed forces.

Other manufacturers and the aviation press widely ridiculed and spoofed many of these marketing terms but between Cessna ’ s designers producing a product the flying public wanted and the work of the marketing department, Cessna built and sold more aircraft than any other manufacturer during the boom years of the 1960s and 1970s.

They even went as far as to say pilots could do “ drive-up take-offs and drive-in landings ”, implying that flying these aircraft was as easy as driving a car.

At that moment the aircraft was flying through a heavy rainstorm over the Lewis River in southwestern Washington.

A flying car or roadable aircraft is an aircraft that can also travel along roads.

A slightly different concept that is sometimes referred to as a " flying car ", particularly in science fiction, is that of an aircraft that would be practical enough for every-day travel, but would not necessarily be drivable on the roads.

* The Moller Skycar M400 is a prototype personal VTOL ( vertical take-off and landing ) aircraft that some refer to as a flying car, although it cannot be driven as an automobile.

* The Milner AirCar is an advanced composite four-door, four-passenger roadable aircraft ( flying car ) with foldable main wing at the rear and foldable canard in the front.

In April 1917, during a brief period of German aerial supremacy, a grandstanding Member of Parliament ( upset at the lack of orders for his own aircraft manufacturing firm ) claimed that, on the Western Front, a British pilot's average life expectancy was 93 flying hours, or about three weeks of active service.

Kites were the precursors to the traditional aircraft, and were instrumental in the development of early flying craft.

In Canada, recreational flying accounted for 0. 7 fatal accidents for every 1000 aircraft, while air taxi accounted for 1. 1 fatal accidents for every 100, 000 hours.

When flying on an aircraft, a man decides to always bring a bomb with him.

While Howland Island was colonized in 1935 as a future aviation facility and is known in popular culture mostly because of its association with the last flight of Earhart and Noonan, no aircraft is known to have ever landed there, although anchorages nearby could be used by floatplanes and flying boats during World War II.

It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan.

However, any aircraft operating under VFR must have the required equipment on board, as described in FAR Part 91. 205 ( which includes instruments necessary for IFR flight ); but the view outside of the aircraft is the primary source for keeping the aircraft straight and level ( orientation ), flying where you intended to fly ( navigation ), and for not hitting anything ( separation ).

The turrets carried four. 50 inch ( 12. 7 mm ) machine guns, which were designed to be adjusted to converge at the single point where enemy aircraft were expected to appear at low altitude in conduction of strafing runs directed at large infantry and field artillery units.

Cannon have been used extensively in fighter aircraft since World War II, and in place of machine guns on land vehicles.

As a counterbalance to deficiencies in manpower and morale, the British had a considerable advantage in terms of equipment, possessing machine guns, armoured cars, motor transport, wireless communications and aircraft and it was the latter that would prove decisive.

The word " fighter " was first used to describe a two-seater aircraft with sufficient lift to carry a machine gun and its operator as well as the pilot.

French aircraft designer Raymond Saulnier patented a practical device in April 1914, but trials were unsuccessful because of the propensity of the machine gun employed to hang fire due to unreliable ammunition.

Wintgens ' aircraft, one of the five Fokker M. 5K / MG production prototype examples of the Eindecker, was armed with a synchronized, air-cooled aviation version of the Parabellum MG14 machine gun.

Because he was prohibited by contract from racing for four years, the Scuderia briefly became Auto Avio Costruzioni Ferrari, which ostensibly produced machine tools and aircraft accessories.

A machine gun is a fully automatic emplaceable weapon, most often separated from other classes of automatic weapon by the use of belt-fed ammunition ( though some designs employ drum, pan or hopper magazines ), generally in a rifle-inspired caliber ranging between 5. 56 × 45mm NATO (. 223 Remington ) for a light machine gun to as large as. 50 BMG or even more larger for crewed or aircraft weapons.

* American M1919 Browning machine gun: originally chambered for. 30-06 Springfield but has since been converted to a variety of calibers ; it was used as an infantry weapon ( light and support roles ) and also mounted on a variety of vehicles, aircraft and naval platforms.

The machine had insufficient range ( 1440 km ) to operate over Britain, but had machine guns for use against aircraft and experimental 80 kg bombs.

Many aircraft were equipped with machine cannon, and similar cannon ( nicknamed " Pom-pom guns ") were used as antiaircraft weapons.

Closeup of M2 – This machine gun is part of a complex armament subsystem ; it is aimed and fired from the aircraft rather than directly

On ships and aircraft machine guns are usually mounted on a pintle mount – basically a steel post that is connected to the frame.

Originally developed as an aircraft weapon, it also saw some use by infantry as a light machine gun.

: machine building ( aircraft, trucks, and automobiles ; tanks and weapons ; electrical equipment ; agricultural machinery ); metallurgy ( steel, aluminum, copper, lead, zinc, chromium, antimony, bismuth, cadmium ); mining ( coal, bauxite, nonferrous ore, iron ore, limestone ); consumer goods ( textiles, footwear, foodstuffs, appliances ); electronics, petroleum products, chemicals, and pharmaceuticals

Technological advancements changed the way war was fought, as new inventions such as machine guns, tanks, chemical weapons, grenades, and military aircraft modified tactics and strategy.

In the early stages of the air war in World War I the problem of mounting a forward-firing machine gun on combat aircraft was considered by a number of individuals.

However, the air cycle machine is very common on gas turbine-powered jet aircraft as cooling and ventilation units, because compressed air is readily available from the engines ' compressor sections.

Other methods of refrigeration include the air cycle machine used in aircraft ; the vortex tube used for spot cooling, when compressed air is available ; and thermoacoustic refrigeration using sound waves in a pressurized gas to drive heat transfer and heat exchange ; steam jet cooling popular in the early 1930s for air conditioning large buildings ; thermoelastic cooling using a smart metal alloy stretching and relaxing.

The earliest known aerial victory with a synchronised machine gun-armed fighter aircraft occurred in 1915, by German Luftstreitkräfte Leutnant Kurt Wintgens.

It was to be the last Parnall machine to fly, after which Parnall turned his attention to producing aircraft gun turrets to Archie Frazer Nash's design in the Yate factory until the war ended.

It is mainly oriented towards transportation, i. e., the auto industry, shipbuilding, diesel engines, aircraft manufacture, and machine tools, with the auto industry being the leading sector ( 50 %).

The machine construction industry consists primarily of a highly developed military-industrial complex of large scale aircraft and ship building enterprises.
