For an aircraft weighing 3,500 lb, how much fuel is consumed climbing to 10,000 feet pressure altitude?

To determine fuel consumption during a climb to 10,000 feet pressure altitude for an aircraft weighing 3,500 lb, we typically consider the climb performance data, which provides a rough estimate based on the aircraft's weight and the specific fuel consumption characteristics of the engines involved.

The fuel consumption during climbs tends to follow a trend based on the engine's efficiency and the rate of climb along with altitude change. For many light aircraft, it is rough practice to estimate that the fuel used in climbing to 10,000 feet is about 1-2 pounds of fuel per 1,000 feet of altitude gained for aircraft around this weight range.

Therefore, when you calculate the fuel consumption based on this estimation approach, consuming approximately 35 pounds of fuel while climbing to 10,000 feet is a realistic figure. This reflects the necessary thrust required to overcome drag and maintain climb rate at a given weight, supporting the idea that the estimate for fuel consumption aligns with general data for fuel burn during climbs.

Thus, based on common fuel burn metrics for climbs and the aircraft's weight, the figure of 35 pounds aligns well with standard expectations for fuel consumption in such profiles, making it the correct answer.
