Which airspace is considered uncontrolled?

• A. Uncontrolled airspace is Class G
• B. Class E is uncontrolled
• C. Class B is uncontrolled
• D. Class C is uncontrolled

Answer: (A)

Uncontrolled airspace means ATC does not provide separation services, and pilots aren’t required to obtain an ATC clearance for VFR operations. The only airspace in the United States that fits this description is Class G. It extends from the surface up to the base of the overlying controlled airspace (Class E), with the base typically at 700 or 1,200 feet AGL depending on the area. All other airspace (A, B, C, D, and E) is controlled, with ATC services and specific procedures and weather minimums. So the airspace that’s considered uncontrolled is Class G.
