One of the least known and most vital roles in support of international civil aviation is filled by the Aeronautical Information Service (AIS). The objective of the Aeronautical Information Service is to ensure the flow of information necessary for the safety, regularity and efficiency of international air navigation. The manner in which aeronautical information is gathered and managed is governed by Annex 15 to the Convention on International Civil Aviation (ICAO Annex 15), which defines how an aeronautical information service shall receive and/or originate, collate or assemble, edit, format, publish/store and distribute specified aeronautical information/data. The goal is to satisfy the need for uniformity and consistency in the provision of aeronautical information/data that is required for operational use by international civil aviation. ICAO Annex 15 specifies that aeronautical information should be published as an integrated aeronautical information package (IAIP), composed of the following elements: * The Aeronautical Information Publication (AIP), including amendment services * * AIP supplements * Aeronautical Information Circulars (AIC) * NOTAM (Notice to Airmen)—alerts aircraft pilots of any hazards en route or at a specific location * * Checklists and lists of valid NOTAM * Pre-flight Information Bulletins (PIB) Each element is used to distribute specific types of aeronautical information. ==ICAO Annex 15== The ICAO Council first adopted the original Standards and Recommended Practices in 1953. Annex 15 has its origins in Article 37 of the Chicago Convention. A total of 35 amendments updated Annex 15 over the years to meet the rapid changes brought about by air travel and associated information technology. In recent years, Annex 15 amendments have reflected the increased need for the timely provision of quality aeronautical information/data and terrain data as they have become critical components of data-dependant on-board navigation systems. The Annex now contains many provisions aimed at preventing corrupt or erroneous aeronautical information/data which can potentially affect the safety of air navigation. The philosophy underlying Annex 15, which stems from Article 28 of the Convention on International Civil Aviation, is that each State is responsible for making available to civil aviation interests any and all information which is pertinent to and required for the operation of aircraft engaged in international civil aviation within its territory, as well as in areas outside its territory in which the State has air traffic control or other responsibilities. 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「aeronautical information service」の詳細全文を読む スポンサード リンク
