The CAA oversees the Certification, Designation, and approval of civil ATS in the UK, including equipment and safety procedures involved in the provision of an ATS. The CAA also oversees the training and licensing of personnel involved in the provision of an ATS (primarily Air Traffic Controllers (ATCOs) and Flight Information Service Officers (FISOs)). Military services are regulated by the military authorities.
Aerodrome ATS are provided by the aerodrome operating authority or contracted Certificated and Designated ANSP.
En-Route ATS are provided by NATS under a licence issued by the Minister of State for Transport.
