What is the landing ground roll under conditions where the temperature is 50 °F, pressure altitude 2,000 feet, weight 3,200 lb, and wind is calm?

• A. 1,500 feet
• B. 800 feet
• C. 600 feet
• D. 700 feet

Answer: (B)

To determine the landing ground roll, several factors such as temperature, pressure altitude, aircraft weight, and wind conditions are taken into account. In this scenario, the given conditions are a temperature of 50 °F, a pressure altitude of 2,000 feet, an aircraft weight of 3,200 pounds, and calm wind conditions. When calculating landing performance, the temperature and pressure altitude are crucial as they influence air density, which affects lift and drag. At a pressure altitude of 2,000 feet, the density of air is lower than at sea level, resulting in a longer landing roll compared to standard conditions. However, at a temperature of 50 °F, which is close to standard temperature for that altitude, the effects are somewhat mitigated. The weight of the aircraft also plays a significant role, with heavier weights requiring longer landing distances due to the increased momentum that must be dissipated during the landing phase. The calculation would involve using a specific aircraft performance chart or formula that accounts for these variables. Given these conditions, the most accurate estimate for the landing ground roll would be 800 feet. This value reflects the combined effects of weight, altitude, and temperature on landing performance, considering all necessary adjustments for the specific operational conditions
