Definition
In FAA airman certification, a certificate is the primary credential authorizing a person to act as a pilot at a defined level (such as Student, Sport, Recreational, Private, Commercial, or Airline Transport Pilot). A rating is an authorization placed on that certificate that specifies what the holder may fly or under what conditions, including aircraft category, class, and type ratings, as well as operational ratings such as the instrument rating.
Plain English
A certificate is the main pilot license itself. A rating is an add-on to that license that says what kind of aircraft you can fly or what kind of flying you can do.
Context Anchor
Seen in practical test recommendations, where an instructor confirms that an applicant is prepared to test for a specific FAA approval.
Derivation
Certificate comes from the Latin certus, meaning 'sure' or 'settled' — a document that settles the question of whether someone is qualified. Rating comes from the older sense of assigning a level or class — like rating something on a scale. Together, the certificate establishes the qualification and the rating specifies its scope.
Why Pilots Care
It defines the exact legal limits of what operations a pilot may conduct without violating regulations.
Intuition Check
Do not read “certificate” as just a paper document, and do not read “rating” as a score or review. Here, both refer to official FAA authority to exercise specific aviation privileges.
Example Sentence 1
After passing her checkride, she held a Private Pilot certificate with an airplane single-engine land rating.
Example Sentence 2
Adding a multi-engine rating to his certificate let him fly twin-engine airplanes.
