Which airspace is the only airspace described as uncontrolled?

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

Answer: (B)

Uncontrolled airspace means ATC does not provide separation services or clearances. In the United States, that designation is Class G. All other airspace types—Class A, B, C, D, and E—are controlled and involve some level of ATC coordination or clearance to enter. For drone operations, Class G allows you to fly without ATC authorization, as long as you follow Part 107 rules and stay within the applicable altitude and weather limits and clear of controlled airspace boundaries. When you are in or near controlled airspace, you must obtain the proper authorization before flying.
