An Air Operator's Certificate (AOC) in the
UK or an Air Carrier Certificate in the
US is an official document issued to an airline by its national safety regulator. It attests to the airline's competence regarding its ability to conduct a safe operation and clearly defines who is in charge of its safety oversight (the
CAA's Safety Regulation Group near
London Gatwick Airport in the UK). It therefore constitutes the key link to safety oversight.
