An A/C is flying with thrust loading at take-off is 0.9. If thrust at take-off and cruse is equal then, determine the thrust loading during cruise.

An A/C is flying with thrust loading at take-off is 0.9. If thrust at take-off and cruse is equal then, determine the thrust loading during cruise. Correct Answer 0.941

Given thrust at take-off = thrust at cruise = T Cruise thrust loading is given by, (T/W)cruise = (T/W)take-off * (Wtake-off / Wcruise). For cruise Wcruise = 0.956 * Wtake-off Hence, (T/W)cruise = (T/W)take-off * (Wtake-off / 0.956*Wtake-off) = 0.9/0.956 = 0.941.
