Under § 107.51, what is the minimum flight visibility required, as observed from the control station, for small UA operations?

Why: 14 CFR 107.51(c): "The minimum flight visibility, as observed from the location of the control station must be no less than 3 statute miles."

• Understates the regulatory minimum; § 107.51(c) requires at least 3 statute miles, not 1.
• Overstates the regulatory minimum; § 107.51(c) sets the floor at 3 statute miles — a higher personal minimum is allowed but not required by regulation.
