Definition
A certificate issued by the FAA under 14 CFR Part 139 that authorizes an airport to serve scheduled and unscheduled air carrier operations using aircraft with more than nine passenger seats. The certificate is granted only after the airport demonstrates compliance with safety, operational, and emergency-response standards covering areas such as runway condition, firefighting and rescue services, fueling, signage, marking, lighting, and wildlife hazard management.
Plain English
An official FAA approval that says an airport meets the safety standards required to handle airline flights. Without this certificate, airlines aren't allowed to operate scheduled passenger service from that airport.
Context Anchor
Seen in airport certification, airport management, airline service, and Part 139 airport safety discussions.
Derivation
Certificate comes from Latin roots meaning “to make certain.” That fits this term because the certificate is the FAA’s written confirmation that an airport has met required standards for the kind of airline service it provides.
Why Pilots Care
Air carrier operations are only authorized at airports that hold this certificate, confirming the runway, rescue services, and procedures meet federal safety minimums.
Intuition Check
Do not read this as a pilot certificate or an airline certificate. It belongs to the airport, and it shows the airport is approved for certain passenger airline operations.
Example Sentence 1
The regional airport applied for an Airport Operating Certificate after a commuter airline announced plans to begin scheduled service there.
Example Sentence 2
After the runway extension, the airport applied for an updated Airport Operating Certificate to continue serving air carriers.
