What is the minimum visibility requirement for VFR (Visual Flight Rules) flight?

The minimum visibility requirement for VFR (Visual Flight Rules) flight is established to ensure that pilots can operate their aircraft safely in visual conditions. Under VFR, pilots are required to have a minimum visibility of 3 statute miles during the day. This requirement helps to ensure that pilots can see and avoid obstacles, other aircraft, and terrain while flying.

The 3-mile visibility requirement allows for safe navigation and situational awareness, which are critical for pilot decision-making and avoiding collisions. This standard is widely accepted and enforced by aviation authorities to maintain safety in the airspace system.

In comparison, other visibility requirements either do not meet the safety standards set for VFR operations or refer to different types of flight operations. For example, lower visibility figures like 1 mile are typically associated with special VFR conditions, which are more restrictive and not suitable for general VFR operations. Higher visibility requirements, such as 5 or 7 miles, apply in certain controlled airspace or under specific flight conditions, but are not the standard minimum for general VFR use.
