Controlled vs Uncontrolled Airspace is defined by which entities?

• A. NASA/NOAA
• B. DoD
• C. DOT/FAA/ATO/ATS
• D. EPA

Answer: (C)

Defining where controlled versus uncontrolled airspace exists is a function of the civil aviation authority responsible for airspace structure and air traffic services. In the United States, that role is filled by the Department of Transportation through the Federal Aviation Administration, specifically the Air Traffic Organization and its Air Traffic Services. They establish the classifications, procedures, and charting that determine where air traffic control provides separation and control, and where pilots operate without ATC separation. Other agencies listed—NASA/NOAA, DoD, and EPA—do not define airspace classifications; NASA/NOAA are science and weather organizations, DoD is military operations, and EPA handles environmental regulation.
