What method is used to find the fuel burn rate given fuel consumption and time?

To determine the fuel burn rate effectively, the method that involves placing the fuel consumption on the inner scale above the time is correct. This approach utilizes a linear relationship between the two variables—fuel consumption and time—allowing for a straightforward calculation of the rate at which fuel is burned over a given period.

By positioning the fuel consumption value on the inner scale and aligning it with the corresponding time on the outer scale, you can directly read off the burn rate in a clear and efficient manner. This method is particularly useful for quick calculations during flight, ensuring accurate fuel management.

Other methods, while relevant in different contexts, do not provide as direct a means to ascertain fuel burn rate. For example, aligning fuel consumption with the outer scale, dividing total distance by fuel burnt, or adjusting figures based on altitude may serve other purposes, but they do not achieve the same straightforward result for calculating the burn rate in this scenario. Therefore, placing the consumption on the inner scale above the time effectively streamlines the process and delivers accurate results for fuel management in flight operations.
