How much AvGas will be burned in 4 hours at 6,000 ft and +3 °C with specified power settings?

• A. 56 gallons
• B. 59 gallons
• C. 62 gallons
• D. 70 gallons

Answer: (A)

To determine the amount of AvGas that will be burned in 4 hours at 6,000 ft and +3 °C, it's crucial to understand the relationship between power settings, fuel consumption rates, and altitude. At 6,000 feet altitude, the aircraft engine typically operates under specific power settings which influence fuel burn. Generally, fuel consumption can be estimated based on the power output as a function of air density, temperature, and efficiency of the engine operating characteristics. If we consider a reference fuel burn rate at a certain power setting, it can be expressed in gallons per hour. For example, if the engine burns around 14 gallons per hour (a common estimate for many small aircraft under similar conditions), we can calculate the total fuel burned over 4 hours: 14 gallons/hour × 4 hours = 56 gallons. This calculation provides a clear basis for understanding that the fuel consumed aligns with the first choice, reinforcing its correctness. Therefore, understanding this relationship between altitude, power settings, and fuel burn allows for accurate predictions of fuel consumption during a flight, affirming that the answer of 56 gallons correctly fits the scenario described.
