- Definition vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet, countering 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, but which does not rely on reactions of the air against the earth's surface (i.e. as a hovercraft does) to obtain lift Reference COM-EN, based on:1) Wikipedia > aircraft. http://en.wikipedia.org/wiki/Aircraft [15.1.2019]2) Eurocontrol ATM Lexicon > Aircraft, quoting ICAO (1990), 'Annex 2 to the Convention on International Civil Aviation: Rules of the Air', July 1990. https://ext.eurocontrol.int/lexicon/index.php/Aircraft [15.1.2019]
- Comment There are two types of aircraft: lighter than air [ IATE:754450 ], encompassing airships and balloons; and heavier than air [ IATE:1492023 ], encompassing ornithopters, machines that use flapping wings for lift and propulsion, and airplanes. In addition to airplanes with fixed lifting surfaces, the term encompasses autogiros and helicopters, which derive lift, and, in the case of helicopters, power, from rotating wings.Note ref.: John Guilmartin 'aircraft' The Oxford Companion to the History of Modern Science.
