What is the maximum X-Wind for a wet runway?

• A. 31 knots
• B. 38 knots
• C. 20 knots
• D. 18 knots

Answer: (A)

Crosswind control during takeoff and landing is limited by how well the airplane can maintain directional control on the surface. When the runway is wet, friction is reduced and braking effectiveness diminishes, so there’s less margin to compensate for a sideways wind component. Because of that, the ERJ 175 is limited to a lower X-wind on a wet surface to help ensure you can touch down and roll out safely. The published figure for a wet runway is 31 knots, making it the maximum crosswind component you should plan to use in that condition. Dry runways allow a higher limit (around 38 knots), while more adverse surface conditions would push the limit down further.
