What does the Specific Ground Range measure?

• A. Distance per unit of fuel consumed
• B. Distance flown divided by time
• C. Ground Speed divided by fuel flow
• D. Duration of flight divided by distance

Answer: (C)

The Specific Ground Range is a measure that indicates the efficiency of an aircraft in terms of distance traveled over the ground per unit of fuel consumed. This is calculated by taking the ground speed of the aircraft and dividing it by the fuel flow rate (the amount of fuel consumed per hour). The result gives pilots insight into how effectively they are utilizing fuel during flight, making it a crucial parameter for flight planning and fuel management. Higher specific ground range values signify that the aircraft can cover more distance with less fuel, which is essential for optimizing flight paths and reducing operational costs. This metric is particularly beneficial during long flights where fuel efficiency can significantly impact overall performance and safety. In contrast, the other options pertain to different aspects of flight measurements, such as overall distance and time or fuel consumption without focusing specifically on ground range efficiency. These do not accurately capture the essence of what Specific Ground Range represents.
