In flight mechanics, the range of an aircraft refers to the distance it can travel in a straight line from its starting point (typically the point of takeoff) to its final destination before exhausting its fuel and landing. It is a crucial performance parameter for an aircraft and is often a key consideration in flight planning and mission execution.
R = Range of the aircraft (in kilometers) Wf = Amount of fuel consumed by the aircraft (in Newtons of fuel) (km / N of fuel)average = The specific fuel consumption or fuel consumption rate (in kilometers per Newton of fuel, averaged over the entire flight)
