Under the Runway Use Program, what crosswind component is allowed for runways not clear and not dry?

• A. Must not exceed 20 KT
• B. Must not exceed 15 KT
• C. Must not exceed 25 KT
• D. Must not exceed 10 KT

Answer: (B)

Crosswind limits tighten when the runway isn’t clear and not dry because a contaminated surface makes it harder to maintain directional control during takeoff and landing. The Runway Use Program sets a limit of 15 knots for the crosswind component in these conditions. This helps reduce the risk of loss of control or a runway excursion when braking action and tire grip are diminished by moisture or contamination. A higher limit would increase risk, while a much lower one would unnecessarily limit operations on marginally contaminated surfaces. Therefore, 15 knots is the appropriate and safe allowance.
