Definition
A former United States federal agency, created by the Civil Aeronautics Act of 1938, responsible for the day-to-day administration of civil aviation, including pilot certification, airway operation, air traffic control, and enforcement of safety regulations. The CAA existed from 1938 until 1958, when its functions were absorbed into the newly created Federal Aviation Agency (later the Federal Aviation Administration, FAA).
Plain English
The CAA was the U.S. government office that ran the practical side of civil aviation from 1938 to 1958 — licensing pilots, running air traffic control, and enforcing safety rules. It was eventually replaced by the FAA.
Context Anchor
Seen in aviation history discussions about how U.S. aviation regulation developed before the modern FAA.
Derivation
Civil refers to non-military aviation. Aeronautics comes from the Greek 'aer' (air) and 'nautikos' (relating to sailing or navigation) — literally 'navigating the air.' Administration means the body that carries out the rules. Together: the office that runs non-military air navigation.
Why Pilots Care
Understanding the CAA’s role shows how early safety standards evolved into the FAA rules pilots follow today.
Intuition Check
Civil does not mean polite here; it means non-military aviation. Administration does not mean office paperwork only; here it refers to a federal agency with real aviation authority.
Example Sentence 1
Before the FAA was established in 1958, pilot certificates were issued by the Civil Aeronautics Administration.
Example Sentence 2
Pilots trained under CAA rules received certificates that later transferred to the new FAA system.
