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

In Class D airspace, the minimum visibility requirement for Visual Flight Rules (VFR) flight is 3 statute miles. This visibility standard is in place to ensure that pilots have adequate visual reference to navigate and avoid obstacles or other aircraft. Class D airspace typically surrounds airports and is designed to accommodate both visual and instrument flight rules.

Having 3 statute miles of visibility helps ensure that pilots can safely see and avoid other traffic as well as maintain awareness of their environment. This requirement also aligns with the general responsibility of pilots to avoid hazards and operate within visual reference. Thus, meeting this visibility standard is vital for safe flight operations within such airspace.
