What is the maximum crosswind on dry or wet runway?

• A. 25 kts
• B. 20 kts
• C. 30 kts
• D. 35 kts

Answer: (C)

The key idea is the aircraft’s maximum demonstrated crosswind component for takeoff and landing. This is a certification-based limit that defines how much wind blowing across the runway the airplane is approved to handle while controllability is maintained. For this item, the published limit is 30 knots for crosswind on both dry and wet runways. That means, regardless of surface condition, you should not attempt takeoff or landing if the crosswind component exceeds 30 knots. It’s tied to the aircraft’s certification data and pilot procedures, reflecting the level of directional control you can reliably expect within those conditions. Crosswind component is the part of the wind that pushes across the runway, determined from wind speed and direction relative to the runway heading. If the wind is exactly across the runway, the crosswind equals the wind speed. If the wind isn’t directly perpendicular, the crosswind is less than the wind speed, calculated from the angle between wind direction and runway. In gusty conditions, the gust value can temporarily raise the crosswind, so pilots consider gust factors within the published limit. The 30-knot figure here specifically represents the sustained (or the certified) crosswind limit; momentary gusts must still stay within safe operating practices. The other options don’t fit because they imply a lower or higher limit than the certified value: 30 knots reflects the actual maximum, while 20 or 25 would unnecessarily restrict operations, and 35 would exceed what the airplane is certified to handle.
