For a takeoff weight reduction over a 50-foot obstacle at 3,000 feet pressure altitude, what might be the expected reduction when winds calm?

• A. 200 pounds
• B. 100 pounds
• C. 300 pounds
• D. 400 pounds

Answer: (A)

When considering the takeoff weight reduction over a 50-foot obstacle at a pressure altitude of 3,000 feet, understanding how temperature and altitude affect aircraft performance is essential. At this pressure altitude, aircraft engine performance and aerodynamic efficiency can decrease due to thinner air. When winds are calm, pilots often must account for the aircraft's need to achieve a certain speed to generate lift and clear obstacles. In this scenario, a 200-pound reduction in weight is a reasonable estimate, as it reflects the additional weight that an aircraft might need to shed in calm wind conditions to maintain adequate climb rates and ensure obstacle clearance during takeoff. Higher altitudes generally require more careful weight management, as the reduced air density impacts lift generation and engine performance. Therefore, a modest weight reduction like 200 pounds may be sufficient for a typical aircraft in these conditions, allowing it to safely climb and clear the 50-foot obstacle without compromising performance. The other potential weight reduction estimates are likely excessive for typical scenarios, considering the conditions stated, making 200 pounds a well-rounded figure for this specific takeoff situation.
