NATS Holdings (formerly National Air Traffic Services) and commonly referred to as NATS is the main air navigation service provider in the United Kingdom. It inherited the traditions of UK air traffic control, which (founded over Croydon Airport) was the world's first air traffic control regime. It provides en-route air traffic control services to flights within the UK Flight Information Regions and the Shanwick Oceanic Control Area,〔(【引用サイトリンク】title=IVAO Gander / Shanwick Oceanic )〕 and provides air traffic control services to fourteen UK airports. The workforce of NATS is mainly made up of Air Traffic Controllers (ATCOs), Air Traffic Control Engineers (ATCEs), Air Traffic Services Assistants (ATSAs) and Science Technical Analytical and Research Staff (STARs). Administrative and Support staff make up the remainder of the 4,500 or so staff employed by NATS. NATS is split into two main service provision companies: ''NATS En-Route PLC'' (NERL) and ''NATS Services Ltd'' (NSL). * NERL is the sole provider of civilian en-route air traffic control over the UK and is regulated by the CAA who, for example, determine the charges NERL can make. NERL is funded by charging airlines for the provision of air traffic services. * NSL competes for contracts in the free market to provide air traffic control at airports in the UK and overseas, as well as providing related services including engineering, consultancy, information services and training. NATS' en-route business is regulated and operated under licence from the Civil Aviation Authority (CAA). The terms of the licence require NATS to be capable of meeting on a continuous basis any reasonable level of overall demand. They are charged with permitting access to airspace on the part of all users, whilst making the most efficient overall use of airspace. ==History== 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「NATS Holdings」の詳細全文を読む スポンサード リンク
