An Aircraft has gross weight of 10000lb. At the end of the mission segment it has weight fraction as 0.985. Determine fuel consumed for this mission. Correct Answer 150lb

Given, Aircraft gross weight W0 = 10000lb Fuel weight fraction at the end of mission = Wx/W0 = 0.985 Here, there is no provision of reserved fuel is mentioned. So, we are neglecting reserve fuel fraction. Now, from fuel fraction method, Used fuel weight fraction is Wf / W0 = 1 – (Wx / W0) = 1 – 0.985 = 0.015 Hence, fuel consumed during this mission = Wf = W0 * 0.015 = 10000 * 0.015 = 150lb.
