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.

Annex IV ‘Part-ATS’ to Regulation (EU) 2017/373 as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018, includes a requirement for air traffic control service providers to develop, implement and monitor a rostering system in order to manage the risks of occupational fatigue of air traffic controllers.
The CAA has established additional, detailed acceptable means of compliance (AMC) and guidance material (GM) relating to this requirement, to support industry in their implementation of this requirement. These AMC and GM, complemented by a policy document that explains the CAA’s processes for oversight of such a rostering system, replace those previously adopted through ORS9 CAA Decision No 1 dated 22 December 2020.
