When operating in the UK, ensure you are following the UK domestic versions of the regulations (Assimilated EU law), as they are no longer identical to the regulations active in the EU.

CAP 722 states that the relevant EU regulations were transferred into UK domestic law as UK regulations, that these regulations are referred to as 'Assimilated EU law' and will be amended as necessary, and that it should be noted that they no longer mirror the equivalent EU versions.

Figure 1- Regulatory framework The relevant EU regulations were transferred across into UK domestic law, as UK regulations. These regulations are referred to as ‘Assimilated EU law’, and will be amended as necessary. It should be noted that these no longer mirror the equivalent EU versions of the regulation. It should be noted that the names of the ‘Assimilated’ regulations (E.g., COMMISSION IMPLEMENTING REGULATION [EU] 2019/947) have not been substantially changed. However, there are differences, and extreme care must be taken when any reference is made to a regulation to ensure that the regulation made in UK domestic law is being referenced. The revised naming convention that is used is as follows: • Full name of the regulation: “Assimilated Regulation (EU) year/### ” • After first use within a document, the shortened version is used: CAP 722 Series AMC/GM UK Secondary Legislation UK Primary Legislation ICAO Standards & Recomended Practices Chicago Convention 1944 Civil Aviation Act 2012 Air Navigation Order 2016 and subsequennt amendments n/a CAP 722 Basic Regulation 2018/1139 UK Regulation (EU) 2019/947 AMC/GM CAP 722 UK Regulation (EU) 2019/945 AMC/GM CAP 722
