Definition
The Civil Aeronautics Authority was a U.S. federal agency created by the Civil Aeronautics Act of 1938 to regulate civil aviation, including airline economics, airworthiness standards, pilot certification, and air traffic rules. It replaced the aviation oversight role previously held by the Bureau of Air Commerce within the Department of Commerce, and it later evolved into the Civil Aeronautics Board (CAB) and the Federal Aviation Agency, which became today's Federal Aviation Administration (FAA).
Plain English
The CAA was the U.S. government body, set up in 1938, that was in charge of running and policing civil flying. It made the rules for airlines, aircraft, and pilots until its duties were eventually split up and passed on to what is now the FAA.
Context Anchor
Seen in aviation history material, especially when studying how U.S. federal aviation regulation developed before the FAA existed.
Derivation
Civil means non-military. Aeronautics comes from the Greek 'aēr' (air) and 'nautikē' (relating to sailing or navigation), so it literally means 'navigating through the air.' Authority signals that this body had the legal power to make and enforce the rules. Together: the government body with legal power over non-military flying.
Why Pilots Care
The CAA is the direct ancestor of the FAA. Knowing this helps pilots understand why older regulations, accident reports, and historical references mention the CAA rather than the FAA, and how today's regulatory framework was built.
Intuition Check
CAA does not mean a pilot has authority or permission to fly. In this context, it is the name of a former U.S. government aviation agency.
Example Sentence 1

Example Sentence 2
