Air Operator Certificate (AOC)
The European equivalent of a US Part 135 certificate, issued by EASA member-state authorities to companies authorised to conduct commercial air transport.
IN PRACTICE
An AOC is the document that legally enables a company to fly passengers or cargo for hire. The certificate names the company, the aircraft types operated and the approved areas of operation.
Why air operator certificate exists. Air operator certificate is part of the regulatory framework that distinguishes commercial air transport from private flying. The rules protect passengers by setting standards for crew training, maintenance, dispatch and insurance, and they protect the industry by giving every operator the same baseline to compete against.
Air operator certificate under FAA rules. In the United States, air operator certificate is enforced under Title 14 of the Code of Federal Regulations. Operators are audited periodically and must self-report deviations. As a broker we only quote operators whose air operator certificate compliance is current and verifiable.
Air operator certificate under EASA and UK CAA rules. In Europe, the EASA framework implements the same principles through national civil aviation authorities. Operators flying internationally must satisfy the rules of every state they operate to, which is one reason cross-border charter is more complex than a domestic trip.
How air operator certificate shows up on your quote. You won't usually see air operator certificate as a line item, but it shapes which operators can quote your trip, which aircraft they can offer, how many crew are required and what insurance limits apply. Quietly, air operator certificate is one of the main reasons two superficially similar quotes can differ by thousands of dollars.
