Final answer:
When flying in Class E Airspace, the minimum visibility for flight under VFR increases from 3 statute miles to 5 statute miles when at or above 10,000 feet.
Step-by-step explanation:
When flying in Class E Airspace, the minimum visibility for flight under VFR (Visual Flight Rules) increases from 3 statute miles to 5 statute miles when at or above 10,000 feet. Class E Airspace refers to controlled airspace that extends from 1,200 feet AGL (above ground level) up to but not including 18,000 feet MSL (mean sea level). The increase in visibility requirements at or above 10,000 feet ensures safer separation between aircraft and allows pilots to see other planes clearly for better navigation and collision avoidance.
