Question 19
Domain 2: FAA Part 107 WeatherHow close can a small unmanned aircraft operate to a cloud under Part 107?
Correct answer: C
Explanation
Part 107 requires a small unmanned aircraft to remain at least 500 feet below a cloud and 2,000 feet horizontally from a cloud. These cloud-clearance limits are part of the visual line of sight operating rules and are stated as "500 feet below" and "2,000 feet horizontally."
Why each option is right or wrong
A. 500 feet below, 1,000 feet horizontally
B. 400 feet below, 2,000 feet horizontally
C. 500 feet below, 2,000 feet horizontally
14 C.F.R. § 107.51(d) sets the cloud-clearance minimums for small unmanned aircraft: the aircraft must remain at least 500 feet below a cloud and at least 2,000 feet horizontally from a cloud. The question asks for the closest lawful operation under Part 107, so the correct limits are those exact distances, not a lesser separation.
D. No cloud clearance requirements for UAS
