The minimum flight visibility required for VFR flights above 10,000 feet MSL and more than 1,200 feet AGL in controlled airspace is

• A. 3 miles
• B. 5 miles
• C. 1 mile
• D. 2 miles

Answer: (B)

When flying VFR in controlled airspace at high altitude, the visibility requirement increases to five miles. This, combined with the cloud clearance of 1,000 feet above, 1,000 feet below, and 1 mile horizontally, provides enough margin for safe separation in conditions typical of upper airspace. The condition of being above 1,200 feet AGL places you in that high-altitude, controlled-airspace scenario where five miles is required. The other options do not meet this minimum for high-altitude, controlled-airspace operations—three miles is the lower minimum used at lower altitudes, and one or two miles are not sufficient here. Therefore, five miles is the correct minimum.
