What is the minimum visibility requirement for VFR flight?

The minimum visibility requirement for Visual Flight Rules (VFR) flight is indeed 3 statute miles. This standard ensures that pilots have sufficient visual reference with the ground and other aircraft, allowing for safe navigation and avoidance of obstacles. Under VFR, pilots are expected to maintain visual separation from clouds and other aircraft, which requires a clear line of sight. The 3 statute miles requirement reflects an accepted level of visibility that supports safe flight operations in visual conditions.

In different airspace classifications, such as Class G airspace, visibility requirements may vary slightly, but the general rule for VFR operations across much of the United States aligns with this distance. This rule aids in maintaining safety and situational awareness, ensuring pilots can see and assess their surroundings during flight.
