An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, in which a person is fatally or seriously ...
While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects related to aircraft. [1] The term " aviation " is sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships , and includes ballistic ...
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, the air entering the engine must be decelerated to a subsonic speed and then re-accelerated back to supersonic speeds after combustion.
Air travel is a form of travel in vehicles such as airplanes, jet aircraft, helicopters, hot air balloons, blimps, gliders, hang gliders, parachutes, or anything else that can sustain flight. [1] Use of air travel began vastly increasing in the 1930s: the number of Americans flying went from about 6,000 in 1930 to 450,000 by 1934 and to 1.2 ...
Although the language proficiency of aviation professionals who are native speakers of English may typically be considered to be equivalent to Expert Level 6 on the ICAO Scale, they may also be sub-standard communicators in Aviation English, specifically by being prone to the use of non-standard terms, demonstrating impatience with non-native ...
Civil aviation is one of two major categories of flying, representing all non-military and non-state aviation, which can be both private and commercial. Most countries in the world are members of the International Civil Aviation Organization and work together to establish common Standards and Recommended Practices for civil aviation through ...
Naval aviation / Aeronaval is the application of military air power by navies, whether from warships that embark aircraft, or land bases. It often involves navalised aircraft, specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval ...
The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft. Flange – Flap – is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight.
