The European Aviation Safety Agency (EASA) published a consolidated version of Regulation (EU) No 1178/2011, the Aircrew Regulation, and a quick reference guide for flight crew licences and ratings. The rules consolidation includes the initial issue of and all subsequent amendments to the Aircrew Regulation, irrespective of their applicability date.
At the same time EASA prepared a quick reference guide for licences and ratings to support stakeholders and experts working in aviation. This guide is intended to assist licensing officers working for competent authorities and experts working in approved training organisations as instructors or examiners when providing information to stakeholders or other experts.
