Primary sources

Every regulation, AMC/GM document and legislation.gov.uk page this site cites, listed once with the revision checked and the guides and clause pages that cite it.

"Checked" means a named page or document was opened and read directly on the date shown, against the revision shown. Where EASA and eur-lex.europa.eu documents are open access, this site quotes them on clause pages; legislation.gov.uk pages are open access too and are read and verified the same way, but are not quoted on clause pages. The UK CAA's own AMC and GM text lives in a regulatory library that requires a CAA account, so it is not quoted anywhere on this site; UK guidance built on it is described in our own words instead, and the CAA web pages listed below were read without needing that login.
