No person may take off or land under basic VFR at an airport that lies within Class D airspace unless the ground visibility at that airport is at least?

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

Answer: (A)

Basic VFR operations in Class D require at least 3 miles of ground visibility. This minimum helps ensure you can see and avoid other traffic and obstacles in the airport environment during takeoff and landing. Ground visibility is the visibility measured at the surface at the airport. If visibility is lower than 3 miles, you can’t operate under basic VFR there; you’d need an instrument approach or a special VFR clearance if applicable. Among the choices, 3 miles is the required minimum; 5 miles would also meet the requirement but isn’t the minimum value, while 1 and 2 miles do not meet the minimum.
