WeatherQuestion 67 of 100
You are flying at 300 ft AGL with 4 SM flight visibility, and a cloud bank sits about 1,200 ft horizontally from your aircraft. Is this operation legal?
a.Yes, because 4 SM already exceeds the 3 SM visibility minimum
b.Yes, because 300 ft AGL keeps the aircraft below the 400 ft limit
c.No, because flight visibility must be at least 5 SM when near clouds
d.No, because you must remain at least 2,000 ft horizontally from clouds
Explanation
Part 107 requires the small UAS to stay at least 500 ft below and 2,000 ft horizontally away from clouds, so a cloud only 1,200 ft laterally makes the flight illegal even though visibility and altitude are fine. Meeting one requirement does not excuse violating another, so the two "yes" answers fail. The visibility minimum is 3 SM, not 5 SM, so the 4 SM reported here is legal and is not the reason the operation must stop.
