For uncontrolled below 1,000 feet AGL, what is the minimum flight visibility at night?

• A. Not less than 1 mile at night
• B. Not less than 2 miles at night
• C. Not less than 4 miles at night
• D. Not less than 3 miles at night

Answer: (D)

At night in uncontrolled airspace below 1,000 feet AGL, the minimum flight visibility is 3 statute miles. This higher visibility helps you reliably see terrain, obstacles, and other aircraft in low-altitude, night conditions where there’s no air traffic control to assist with separation. The other options fall short of the required minimum for this scenario, while 4 miles is more than the minimum but not necessary. Remember, you must also meet the corresponding cloud-clearance requirements for that airspace, in addition to the visibility minimum.
