Outside controlled airspace, between 1,200 feet AGL and 10,000 feet MSL, the minimum distance below clouds for night VFR is?

Outside controlled airspace, between 1,200 feet AGL and 10,000 feet MSL, the minimum distance below clouds for night VFR is?

• A. 1000 ft
• B. 500 ft
• C. 2000 ft
• D. 0 ft

Answer: (B)

When flying VFR at night outside controlled airspace in the 1,200 AGL to 10,000 MSL band, the weather minimums require you to stay clear of clouds with specific distances: 3 miles of visibility and a cloud clearance of 500 feet below, 1,000 feet above, and 2,000 feet horizontally. The minimum distance below the clouds is 500 feet because you must maintain a buffer beneath any cloud layer to keep visual reference to the ground and allow time to see and avoid other aircraft or terrain as you maneuver. 0 feet below would put you inside the cloud; 1,000 feet below or 2,000 feet horizontal miss the focus of this vertical clearance requirement, which is specifically the 500-foot buffer below cloud bases in this regime.
