Which class of airspace is categorized as uncontrolled?

• A. Class F
• B. Class C
• C. Class G
• D. Class D

Answer: (C)

Class G airspace is considered uncontrolled airspace because it is not actively managed by air traffic control (ATC). Unlike controlled airspace, which includes Classes B, C, and D, where ATC provides separation and advice to aircraft, Class G allows pilots to operate without these services unless they choose to communicate with ATC. This environment is designed to accommodate general aviation and enables pilots to fly more freely, although they are still responsible for their own navigation and separation from other aircraft. Therefore, Class G is the correct answer when identifying uncontrolled airspace.
