What is the maximum X-Wind for standing water, slush, wet snow, or dry snow?

• A. 18 knots
• B. 12 knots
• C. 31 knots
• D. 38 knots

Answer: (A)

Crosswind limits vary with runway surface condition because contamination like standing water, slush, or snow reduces braking effectiveness and directional control. On ERJ 175, when the runway is contaminated in the described ways, the aircraft’s margin to maintain runway alignment during approach and rollout is decreased, so the allowable crosswind is lowered to keep control within safe limits. For standing water, slush, wet snow, or dry snow, the maximum X-wind is 18 knots. This value reflects the reduced rudder authority and tire traction under those conditions, ensuring safe handling during landing. The higher numbers correspond to dry pavement scenarios or less restrictive conditions and aren’t applicable when the runway is contaminated.
