Under Part 107, which airspace requires ATC authorization to enter?

Under Part 107, which airspace requires ATC authorization to enter?

• A. Only classes B C D and E
• B. All airspace
• C. Class G
• D. Class A

Answer: (A)

Part 107 requires ATC authorization to operate whenever you’re in controlled airspace. The controlled airspaces are classes B, C, D, and E, so entering those areas needs approval from ATC (often obtained in real time through LAANC or via a COA). Class G is uncontrolled, so no ATC clearance is needed there. Class A sits above 18,000 feet and isn’t available for small UAS operations under Part 107, so it isn’t part of the typical authorization scenario.
