What fuel flow should a pilot expect at 11,000 feet on a standard day with 65 percent maximum continuous power?

At 11,000 feet on a standard day, operating at 65 percent maximum continuous power, the fuel flow generally falls within a specific range that is representative of efficient cruising conditions for most general aviation aircraft.

When an aircraft is operated at 65 percent power, pilots can expect the fuel flow to decrease compared to lower power settings, as the aircraft becomes more efficient at maintaining altitude and speed due to reduced drag and optimal engine performance characteristics at cruising levels.

For many common general aviation aircraft, particularly those equipped with engines standardized for such operational points, a fuel flow of around 11.2 gallons per hour accurately reflects typical performance metrics for that power setting at a moderate altitude such as 11,000 feet. It aligns with the expectations of fuel consumption rates published in aircraft performance charts or from manufacturer specifications.

Using this understanding of aircraft performance allows pilots to better manage fuel reserves and plan for sufficient operational endurance during flights. Additionally, recognizing expected fuel flow rates aids in flight planning and optimizing the economic performance of the aircraft.
