Outside a runway use program, wind-based runway selection uses wind speed threshold of 5 knots or more. True or False?

• A. False
• B. True
• C. Not specified
• D. Always

Answer: (B)

Wind guides runway choice by favoring the runway that best aligns with the wind to maximize headwind and minimize crosswind. When the wind is at least 5 knots, that effect is significant enough to influence which runway you select. If the wind is below 5 knots, its influence is minor and other factors—like traffic, performance, and length—become more important. So outside a runway use program, using a threshold of 5 knots or more to base wind-driven runway selection is the standard approach.
