What is the recommended minimum safety margin for landing on a contaminated runway?

• A. 10%
• B. 15%
• C. 20%
• D. 25%

Answer: (B)

The recommended minimum safety margin for landing on a contaminated runway is 15%. This margin is critical because contaminated runways—those covered with snow, ice, or other materials—can significantly reduce friction and increase the stopping distance required for an aircraft. By adhering to the 15% safety margin, pilots ensure that they have adequate stopping power to safely come to a halt, considering the unpredictable factors that may affect runway conditions. Such measures are part of standard operating procedures aimed at enhancing safety during landings, particularly in winter or adverse weather conditions. The other options suggest lower or higher margins that might not provide the same level of safety or are considered excessive, which could lead to operational inefficiencies. Ensuring a safety margin of 15% strikes a balance between protocol and practical execution in adverse conditions.
