What is the minimum visibility requirement for VFR flight?

The minimum visibility requirement for VFR (Visual Flight Rules) flight is indeed 3 statute miles. This standard is established to ensure that pilots can maintain sufficient visual reference to the surface while navigating and controlling the aircraft. It is crucial for pilots to be able to see and avoid obstacles, other aircraft, and adverse weather conditions.

This 3 statute miles requirement applies to operations in Class E airspace below 10,000 feet MSL (Mean Sea Level) and is designed to enhance safety by providing pilots with adequate visibility to maintain situational awareness. Additionally, under this visibility condition, pilots are expected to fly with clear reference to the ground and other visual cues.

For lower visibility requirements seen in other options, such as 1 or 2 statute miles, these may apply in certain specific conditions or controlled environments, but they do not meet the standard set for general VFR flight, where maintaining a longer range of visibility is crucial for safety in navigating and operating within the airspace.
