At what altitude does the minimum flight visibility for VFR flight increase to 5 statute miles?

The minimum flight visibility for VFR (Visual Flight Rules) flight does indeed increase to 5 statute miles at certain altitudes, specifically referencing the regulations established by the FAA. The correct context states that at altitudes above 10,000 feet Mean Sea Level (MSL) and if the aircraft is above 1,200 feet Above Ground Level (AGL), the requirement for minimum visibility shifts to 5 statute miles. This regulation is designed to enhance safety and ensure that pilots have adequate visibility to navigate and avoid obstacles, especially at higher altitudes where terrain and weather factors can change significantly.

In contrast, at lower altitudes, the visibility requirements are often different to accommodate for various operational needs and environmental factors. For instance, below these specified altitudes, visibility requirements may allow for lower visibility measures, reflecting the realities of navigating in different airspaces. This adjustment helps manage risk in flight operations, ensuring pilots can maintain visual separation and situational awareness as they operate under VFR.
