What is the difference between NATS and the CAA?
NATS is the UK’s provider of en-route and other air navigation services, whilst the Civil Aviation Authority is the UK’s independent specialist aviation regulator with responsibilities for airspace policy, safety regulation, economic regulation and consumer protection.
Under the Transport Act 2000 the Government issued a licence to NATS to provide en route air traffic services in the UK. The Act gives the CAA the role of economic regulator of NATS. It exercises this role mainly through monitoring and enforcing the conditions in the licence and through modifications to the licence.
