To conduct flight, a visibility of how many statute miles is required?

• A. 2 statute miles
• B. 3 statute miles
• C. 5 statute miles
• D. 10 statute miles

Answer: (B)

Minimum visibility for operating a small UAS under Part 107 is 3 statute miles. This standard exists so you can keep the aircraft in visual line of sight and reliably see and avoid hazards, other aircraft, and obstacles as you fly. If visibility were only, say, 2 miles, you wouldn’t have the same margin to identify potential conflicts or react in time. The options of 5 or 10 miles aren’t the required minimum under the rule, though higher visibility is fine if available. In some airspace or weather scenarios you may have additional restrictions or waivers, but the baseline minimum is 3 statute miles.
