What is the minimum visibility requirement for visual flight rules (VFR)?

The minimum visibility requirement for visual flight rules (VFR) is established to ensure that pilots can safely navigate and operate the aircraft while maintaining visual contact with the ground and other aircraft. According to regulations, the minimum visibility for VFR operations in controlled airspace is typically 3 statute miles during the day. This visibility requirement allows pilots to adequately see and avoid obstacles, other aircraft, and the terrain around them, which is crucial for safe flying in visual conditions.

In addition to visibility, VFR requirements also include minimum cloud clearance, which together ensure that pilots can maintain control of the aircraft based on visual references. While there may be varying visibility requirements in specific airspace categories or under different conditions, the baseline for VFR operations typically starts at 3 statute miles under normal circumstances.
