1.	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.(a) 0.941(b) 0.951(c) 0.961(d) 0.98I had been asked this question in homework.My doubt is from Thrust Weight Ratio-2 in division Thrust-Weight Ratio and Wing Loading of Aircraft Design
Answer» The correct OPTION is (a) 0.941 Easy explanation: 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.
