What is the maximum X-Wind for compact snow?

• A. 20 knots
• B. 18 knots
• C. 12 knots
• D. 31 knots

Answer: (A)

Crosswind limits depend on runway surface condition because friction and handling change with the surface. On compacted snow, the surface offers less grip, so the airplane’s ability to maintain runway alignment and achieve effective braking is reduced. For the ERJ 175 in this context, the published maximum crosswind component for takeoff or landing on a compacted-snow runway is 20 knots. This value represents the highest crosswind that can be safely managed given the airplane’s braking and directional control capabilities on that surface; exceeding it would require considering alternate runways, surface improvements, or stricter operational precautions, especially with gusts that can further reduce controllability. The other options are not the published maximum for compacted snow, and thus are not the safe limit in this scenario.
