UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

The detailed policy requirements and design criteria are set out in CAP 777 - ATC Surveillance Minimum Altitude Charts in UK Airspace. The Air Navigation Service Provider (ANSP) is responsible for the design, accuracy and currency of the ATSMAC and for ensuring that minimum periodic reviews are undertaken.

Sponsors wishing to introduce a new or amend an existing ATCSMAC should notify the CAA using the form available in CAP 777, an example of which is contained in the CAP.
