What is the approximate fuel consumption in gallons for a climb at 75 percent power for 15 minutes?

To find the approximate fuel consumption during a climb at 75 percent power for 15 minutes, it is important to consider the typical fuel burn rate and how it correlates with power settings.

At 75 percent power, a general estimate for fuel consumption in many light aircraft is approximately 12 to 15 gallons per hour. This rate can vary depending on the aircraft type, weight, and environmental conditions, but for the sake of this question, we can use an average figure for calculation.

If we take 12 gallons per hour as a baseline rate for a climb at 75 percent power, then we can determine the fuel consumption for a 15-minute climb. Since there are four 15-minute periods in an hour, the fuel consumed in 15 minutes would be calculated as follows:

12 gallons per hour ÷ 4 = 3 gallons for 15 minutes.

However, considering climb performance and the possibility of higher consumption rates for certain aircraft, it is also reasonable to account for conditions that might push that figure slightly higher, often leading to a consumption of around 4.5 gallons for many common training and light aircraft models.

Thus, estimating fuel consumption during a climb at 75 percent power gives a rounded figure that suggests
