What is the minimum visibility requirement for VFR flight in Class D airspace?

For VFR (Visual Flight Rules) flight in Class D airspace, the minimum visibility requirement is 3 statute miles. This requirement is established to ensure that pilots can see and avoid other aircraft and obstacles while flying under visual flight rules. Class D airspace is typically found around airports that have an operational control tower, and maintaining this level of visibility allows for the safe conduct of both VFR and IFR (Instrument Flight Rules) operations.

In addition to visibility, VFR pilots must also adhere to specific cloud clearance requirements dictated by FAA regulations to maintain safe separation from clouds and other aircraft. With 3 statute miles of visibility, pilots have sufficient distance to visually locate, identify, and navigate around obstacles and to ensure they are aware of other air traffic in the vicinity.

The other options present differing visibility requirements that exceed or do not meet the minimum standard for Class D airspace. For instance, 1 statute mile would not provide adequate visibility for safe flight operations, while 5 and 10 statute miles represent more stringent standards suitable for other airspace classifications or conditions. Thus, the correct answer aligns directly with the FAA's regulations for VFR operations specifically in Class D airspace.
