What is the minimum flight visibility required for VFR flight operations on an airway below 10,000 feet MSL?

1. 1 mile

2. 2 miles

3. 3 miles

4. 4 miles

The correct answer is: 3 miles

For VFR (Visual Flight Rules) flight operations on an airway below 10,000 feet MSL (Mean Sea Level), the minimum flight visibility required is 3 miles. This regulation is designed to ensure that pilots have adequate visibility to navigate visually and maintain separation from other aircraft. The requirement of 3 miles allows pilots to see and avoid obstacles, terrain, and other air traffic while flying in the vicinity of controlled airspace or along airways. In practical terms, this visibility rule helps maintain safety in the airspace, as it enhances a pilot's ability to make timely decisions while flying. For example, at night or in marginal weather conditions, having a minimum of 3 miles visibility contributes to a greater safety margin compared to lower visibility requirements. Understanding these regulations is fundamental for pilots when planning their flights and ensuring compliance with aviation safety standards.
