Which airspace is uncontrolled by Air Traffic Control?

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

Answer: (A)

Uncontrolled airspace means ATC does not provide traffic separation or require two-way radio communication. In the U.S., that space is Class G. It begins at the surface and goes up to the base of the controlled airspace above it (near airports the base is typically 700 or 1200 feet AGL; in remote areas, Class G can extend up to 14,500 feet MSL). Because ATC doesn’t provide services there, you fly without ATC clearance and must manage your own separation under visual flight rules, while still obeying other applicable rules for your operation. If you need to fly in controlled airspace, you’d need proper authorization (for example, LAANC) before operating there.
