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

• A. 1 mile
• B. 3 miles
• C. 5 miles
• D. 10 miles

Answer: (B)

VFR flight on a federal airway occurs in Class E airspace, and below 10,000 feet MSL the standard VFR minimums require at least three statute miles of visibility. In addition, you must stay clear of clouds with a separation of 500 feet below, 1000 feet above, and 2000 feet horizontally, but the key point for this question is the visibility requirement. One mile would only apply under Special VFR near an airport, not on an airway. Five miles is the minimum used above 10,000 feet MSL, and ten miles is not a typical VFR minimum for these airspace conditions. So three miles is the correct minimum.
