Which Part governs unmanned aircraft systems (UAS) operations?

• A. Part 77
• B. Part 107
• C. Part 150
• D. Part 36

Answer: (B)

Understanding what rules apply to flying drones hinges on recognizing the regulation that specifically covers unmanned aircraft systems operations in the national airspace. This Part sets the requirements for small UAS flights, including who can operate (remote pilot certificate), how high you may fly (typically up to 400 feet AGL), and basic rules like keeping the aircraft in visual line of sight and obtaining waivers for certain operations. It is the framework most drone pilots follow for commercial and other non-recreational flights, as it directly governs how UAS are operated. The other Parts address different topics: one deals with airspace around airports and clearance requirements, another with airport noise planning, and another with airworthiness standards for traditional manned aircraft. So the regulation that directly governs UAS operations is the Part focused on small UAS operations in the national airspace.
