Which statement about the minimum ground visibility for basic VFR within Class D airspace is true?

• A. 2 miles
• B. 3 miles
• C. 4 miles
• D. 5 miles

Answer: (B)

In Class D airspace, basic VFR requires enough visibility to safely see and avoid other aircraft and obstacles. The minimum is 3 statute miles of ground (flight) visibility, plus the standard cloud clearance: stay 500 feet below, 1000 feet above, and 2000 feet horizontally from clouds. This combination helps ensure you can detect other traffic and maintain safe separation while operating in controlled airspace. If visibility falls below 3 miles, you’re no longer operating under basic VFR in that Class D area and would need to pursue other options such as operating under a different weather basis or, if applicable, a Special VFR clearance.
