A flight information service (FIS) is a form of air traffic service which is available to any aircraft within a flight information region (FIR), as agreed internationally by ICAO. It is defined as information pertinent to the safe and efficient conduct of flight, and includes information on other potentially conflicting traffic, possibly derived from radar, but stopping short of providing positive separation from that traffic. Flight Information also includes: *Meteorological information *Information on aerodromes *Information on possible hazards to flight FIS shall be provided to all aircraft which are provided with any air traffic controller (ATC) service or are otherwise known to air traffic service units. All air traffic service units will provide an FIS to any aircraft, in addition to their other tasks. ==Aerodrome Flight Information Service== In most countries, an Aerodrome Flight Information Service (AFIS)〔In the United States, the acronym AFIS is usually understood to stand for "Automatic Flight Information Service".〕 is provided at airfields where, despite not being busy enough for full air traffic control, the traffic is such that some form of service is necessary. It can be seen as a half-way house between an uncontrolled and controlled airfield: As a part of the FIS, the AFIS provides pilots of aircraft with details of other known traffic taking off, landing and flying in the vicinity of the airfield. 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「flight information service」の詳細全文を読む スポンサード リンク
