Which maximum X-Wind value is 12 knots?

Which maximum X-Wind value is 12 knots?

• A. 12 knots
• B. 38 knots
• C. 31 knots
• D. 20 knots

Answer: (A)

X-wind is the crosswind component along the runway centerline, the wind portion that directly affects directional control during takeoff and landing. The maximum X-wind value is the published ceiling for safe operations; if the crosswind exceeds this limit, operations aren’t authorized because control authority and margins can be compromised. In this item, the only value that matches the published limit of 12 knots is 12 knots, so that choice is the correct one. The other numbers (38, 31, 20) are higher crosswind figures and do not represent the specified 12-knot cap for this scenario.
