Unless operating within 400 feet of a structure, what is the maximum altitude at which a small unmanned aircraft may be operated under Part 107?

• A.400 feet AGL
• B.500 feet AGL
• C.400 feet MSL

Why

Section 107.51(b) caps the altitude of the small unmanned aircraft at 400 feet above ground level. The limit is measured in AGL, not MSL, and 500 feet is the minimum distance you must stay below clouds, not an operating altitude.
