What are the minimum visibility requirements for VFR flight?

The minimum visibility requirements for VFR (Visual Flight Rules) flight are designed to ensure that pilots can see and avoid other aircraft, maintain visual reference to the ground or surface, and navigate safely. In Class G airspace, which is uncontrolled airspace, the requirements are stipulated based on the level of illumination and the time of day.

For VFR flight in Class G airspace, the correct visibility requirements include at least three statute miles during the day. This requirement allows pilots sufficient visual range to operate safely while maintaining situational awareness and the ability to visually separate from other air traffic. At night, the visibility requirement increases to five statute miles, as the lack of natural light at night necessitates greater distance for the pilot to identify and avoid other traffic, ground obstacles, and maintain orientation.

Therefore, the answer that states at least three statute miles during the day and five statute miles at night aligns with these safety guidelines, which are grounded in the need for adequate visibility under varying lighting conditions. Recognizing these requirements is critical for ensuring safe flight operations in uncontrolled airspace.
