Outside a runway use program, use the runway most nearly aligned with the wind when the wind is ______ KT or more.

• A. 7
• B. 3
• C. 5
• D. 9

Answer: (C)

The idea is to minimize crosswind by using the runway that is most closely aligned with the wind. When winds reach a noticeable level, aligning the runway with the wind helps keep the aircraft tracking straight during takeoff and landing, making control easier. Outside a runway use program, you apply this alignment rule when the wind is five knots or more; below that, the benefit is small and other factors (traffic, availability) become more important. So the minimum wind at which you should start selecting the runway most nearly aligned with the wind is five knots, which is why five is the correct fill. Winds higher than that (like seven or nine knots) would also warrant using the best-aligned runway, but the question focuses on the threshold.
