Which airspace is uncontrolled airspace, typically below 700 feet AGL or 1,200 feet AGL?

Which airspace is uncontrolled airspace, typically below 700 feet AGL or 1,200 feet AGL?

• A. Prohibited airspace
• B. Restricted airspace
• C. Uncontrolled airspace, below 700'AGL or 1200'AGL
• D. Class A airspace

Answer: (C)

Uncontrolled airspace is the airspace where ATC does not provide separation services. In the U.S., this is typically Class G, which extends from the surface up to the base of the overlying controlled airspace (Class E). That base is not fixed; in many areas it begins at 700 feet AGL, or at 1,200 feet AGL in others. So the airspace below those bases is uncontrolled. Prohibited and restricted areas are special-use airspace with access restrictions, and Class A is the high-altitude controlled airspace starting at 18,000 feet. The description that matches “uncontrolled airspace below 700' AGL or 1,200' AGL” is the correct one.
