What is the minimum visibility requirement for VFR flight?

The minimum visibility requirement for Visual Flight Rules (VFR) flight is generally established at 3 statute miles. This standard reflects the need for pilots to maintain sufficient visual reference to the ground and navigate effectively while avoiding obstacles and other aircraft.

In controlled airspace and for various aircraft categories, these visibility requirements ensure safe operation. If visibility is less than 3 miles, pilots may face challenges in visual navigation, which is critical for VFR flight. Furthermore, the 3-mile visibility helps in maintaining adequate spacing between aircraft and allows pilots to make timely decisions to avoid hazardous conditions.

It's important to note that specific visibility requirements can change based on airspace classification or local regulations, but the 3-mile standard is a widely recognized benchmark in most situations concerning VFR flight.
