Takeoff crosswind on a dry runway with flaps greater than 5?

• A. 40 knots
• B. 25 knots
• C. 30 knots
• D. 35 knots

Answer: (C)

Crosswind takeoff limits are set for specific conditions because the ability to hold centerline and rotate safely depends on flap setting and runway surface. When you have flaps extended beyond five degrees, you gain more lift at lower speeds, but you also increase the airplane’s side area and drag and reduce rudder effectiveness. That makes controlling the aircraft in a crosswind more challenging during the takeoff roll and the initial climb.

On a dry runway, the friction helps you stay on centerline, but the combination of extended flaps and crosswind still tightens the margin for safe control. The published limit for this exact setup balances having enough control authority to maintain runway alignment and a stable liftoff with the demonstrated performance data. Limits that are higher would exceed tested and certified capability for this condition, while limits tied to other conditions (different flap settings or surface conditions) aren’t applicable here.

So, the value that corresponds to a moderate crosswind capability for a dry runway with flaps greater than five is the correct choice, reflecting the tested and safe margin for that scenario.
