An aerodrome or airdrome is a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither. Aerodromes include small general aviation airfields, large commercial airports, and military airbases. The term ''airport'' may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that an aerodrome may not have achieved. That is to say, all airports are aerodromes, but not all aerodromes are airports. Usage of the term 'aerodrome' remains more common in the UK and Commonwealth nations, and is conversely almost unknown in American English. A water aerodrome is an area of open water used regularly by seaplanes or amphibious aircraft for landing and taking off. According to the International Civil Aviation Organization (ICAO) an aerodrome is "A defined area on land or water (including any buildings, installations, and equipment) intended to be used either wholly or in part for the arrival, departure, and surface movement of aircraft."〔International Civil Aviation Organization (ICAO) Documents, Annex 14 to The Convention on International Civil Aviation (Chicago Convention), Volume I- Aerodrome Design and Operations under Definitions〕 == Etymology == The word ''aerodrome'' is derived from the Greek words ''aeras'' (αέρας), "air" and ''dromos'' (δρόμος), "road" or "course", literally meaning "air course". An ancient example was the term Hippodrome (stadium for horse racing and chariot racing, derived from ''hippos'' (ἵππος; "horse") and ''dromos'' (δρόμος; "course"). In the UK, the term was used by the Royal Flying Corps in the First World War and the Royal Air Force in the First and Second World War as it had the advantage that their French allies, on whose soil they were based and with whom they co-operated, used the cognate term ''aérodrome''. In Canada〔(Transport Canada AIM - AGA 2.0 Aerodromes and Airports )〕 and Australia,〔(Commonwealth Consolidated Acts )〕 ''aerodrome'' is a legal term of art for any area of land or water used for aircraft operation, regardless of facilities. The term ''aerodrome'' is used in International Civil Aviation Organization (ICAO) documents, for example, in the Annex to the ICAO Convention about aerodromes, their physical characteristics, and their operation. However, the term ''airfield'' or ''airport'' has mostly superseded use of ''aerodrome'' after World War II. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「aerodrome」の詳細全文を読む スポンサード リンク
