If the cruise altitude is 7,500 feet and using 64 percent power, what is the maximum distance that can be traveled?

To determine the maximum distance that can be traveled at 7,500 feet while using 64 percent power, one must consider the aircraft's specific performance metrics at this altitude and power setting. In general, cruise performance is influenced by the power available from the engine, the airplane's aerodynamic efficiency, and the overall weight of the aircraft.

At 64 percent power, the aircraft can achieve a specific range because it is utilizing a portion of the available power while maintaining an optimal level of performance. At this altitude, aircraft tend to have a favorable lift-to-drag ratio, allowing for more efficient flight over longer distances compared to either lower or higher altitudes, where performance may not be as optimized.

The calculation typically involves assessing the altitude and power setting against specific fuel consumption and range performance charts for the specific aircraft type, which are based on empirical flight testing data. For many general aviation aircraft, cruising at an altitude of 7,500 feet often aligns with favorable performance characteristics that might indicate a maximum distance capability of around 810 miles when flying at 64 percent power.

Thus, the distance of 810 miles represents the maximum range possible under these circumstances, making it the correct answer. Understanding how these factors interplay helps pilots optimize their flights for efficiency and
