The A2 CofC (Certificate of Competency) is a remote pilot competency certificate primarily intended to assure safe operations of drones close to uninvolved persons. The A2 CofC allows pilots to fly small drones up to 2kg "close to people" - maintaining a 50m horizontal separation distance from uninvolved people. It was introduced as part of the new drone regulations, which started in the UK and throughout Europe in December 2020. The A2 CofC is specifically for the Open Category.
