WeatherQuestion 65 of 100
The airport nearest your job site reports OVC012. What is the highest altitude you may operate your small UAS under Part 107?
a.700 ft AGL, since staying 500 ft below the 1,200 ft ceiling is the only limit
b.1,200 ft AGL, since you may operate right up to the reported cloud base
c.400 ft AGL, since 500 ft below the clouds allows 700 ft but 400 ft still applies
d.200 ft AGL, since you must remain 1,000 ft below any overcast layer
Explanation
OVC012 is an overcast base at 1,200 ft AGL, and the required 500 ft of clearance below clouds would permit 700 ft AGL, but Part 107 separately caps routine operations at 400 ft AGL, so 400 ft is the controlling limit. When two rules apply, the more restrictive one governs. Flying at 700 ft would bust the altitude limit, flying at the cloud base violates cloud clearance, and there is no 1,000 ft below-cloud requirement for Part 107.
