When the temperature is 80°F, pressure altitude is 2,000 ft, and weight is 3,400 lb, what is the takeoff distance required to clear a 50-foot oil rig?

To determine the takeoff distance required to clear a 50-foot obstacle, it is important to consider the factors affecting aircraft performance, which include temperature, pressure altitude, weight, and the specific aircraft characteristics.

In this scenario, the provided temperature of 80°F and pressure altitude of 2,000 feet result in performance degradation. As temperature increases or pressure altitude rises, the aircraft engine’s performance, lift generation, and propulsive efficiency can be negatively affected, resulting in longer takeoff distances. The weight of the aircraft also plays a critical role; a heavier weight increases required runway length for takeoff because it requires more speed to generate the necessary lift.

Calculation of takeoff distance involves utilizing performance charts specific to the aircraft type that account for these variables. The answer of 1,250 feet aligns with typical performance expectations under the given conditions because it appropriately considers the balance between the altitude, temperature, weight, and the obstacle clearance requirement. Choosing this distance indicates a more realistic assessment of takeoff performance given the conditions described, suggesting that it provides a safety margin to ensure successful clearance of the 50-foot obstacle.

Understanding these principles helps pilots make informed calculations and decisions during flight planning to ensure operational safety and efficiency.
