Which minimums are typically associated with sUAS operations under VFR conditions in terms of altitude, visibility, and cloud clearance?

• A. Altitude 100' AGL; 1 SM visibility; No cloud rules
• B. Altitude 400' AGL; 3 SM visibility; Cloud clearance 500' below and 2000' horizontal
• C. Altitude 1000' AGL; 5 SM visibility; Clear of clouds
• D. Altitude 200' AGL; 2 SM visibility; Cloud clearance 1000' above

Answer: (B)

When operating a small UAS under visual flight rules, you must stay in weather that allows you to see and avoid other aircraft and to avoid flying into clouds. The typical minimums used in sUAS practice reflect a safe, conservative baseline: altitude limit of 400 feet above the ground, visibility of at least 3 statute miles, and cloud clearance of 500 feet below the cloud and 2,000 feet horizontally from the cloud (you still stay clear of clouds). This combination is the best fit because it ensures you’re high enough above ground clutter and obstacles, have enough visibility to spot other air traffic, and maintain a safe buffer from any cloud layer. The numbers align with standard VFR weather minimums in many airspaces, adapted to the drone operation context. The other options either propose an altitude well outside the typical 400-foot limit, or omit the cloud-clearance requirements, or reduce visibility below what is generally required for safe VFR operation, which makes them unsuitable for standard sUAS VFR practice.
