What does the Specific Ground Range measure?

The Specific Ground Range measures the efficiency of fuel usage relative to the distance covered on the ground. It is expressed as the distance flown divided by the fuel flow, which provides a direct indication of how far an aircraft can travel per unit of fuel consumed. This metric is essential for flight planning and operational efficiency, allowing pilots and airlines to assess fuel needs and optimize routes based on fuel efficiency.

By calculating Ground Speed and relating it to fuel flow, pilots can make informed decisions regarding fuel management during a flight, aiming for a balance between speed and fuel economy. This understanding is critical in ensuring that aircraft operate within their optimal performance parameters, especially on longer flights where fuel conservation becomes increasingly important.
