How much must the required landing distance on a dry runway be increased when conditions indicate the runway may be wet?

• A. 20%
• B. 18%
• C. 15%
• D. 17.6%

Answer: (C)

When transitioning from a dry runway to a wet runway, it is essential to consider the changes in required landing distance due to reduced friction and increased stopping distance on a wet surface. The increase in landing distance is typically standardized to ensure safety during operations. The recommended increase in the required landing distance on a wet runway is commonly accepted to be around 15%. This percentage reflects the decrease in braking efficiency and the increased distance needed for safe stopping under wet conditions. The increase accounts for factors like hydroplaning and the lower coefficient of friction inherent to wet surfaces. Understanding this adjustment is crucial for pilots to ensure they are prepared for varying runway conditions and can make appropriate calculations for safe landings. Using the correct increase in landing distance helps prevent incidents related to insufficient stopping distance in adverse weather conditions.
