What is the purpose of crosswind correction factors in landing distance estimates?

• A. Crosswind corrections apply only to climb performance.
• B. Crosswind correction factors are applied to takeoff distance estimates.
• C. Crosswind has no effect on landing distance.
• D. Apply crosswind correction factors to landing distance estimates.

Answer: (D)

Crosswind adds a sideways component to the landing, which changes how the aircraft sits on the runway and how you manage control during the flare and touchdown. To stay aligned with the runway and maintain control, pilots use approaches like a crab or a wing-low sideslip, both of which can reduce braking effectiveness and increase the distance needed to decelerate and settle onto the runway. Because of this additional runway requirement under crosswind conditions, performance data include crosswind correction factors to adjust landing distance estimates so they remain conservative and safe. This reflects how crosswind affects the actual distance required to land, not just climbs or takeoff, and not as if there were no effect.
