5.39 Consider the following jet aircraft that has a fuel capacity of 10,000 kg and specific fuel consumption of 0.7 lb/h/lb. S=217 m, mro = 63,000 kg, K=0.043, CD = 0.021, CL = 1.7 a. What would be the range (in km) if it flies with a constant speed of 160 m/s and constant angle of attack, assuming that the aircraft begins its flight at 18,000 ft altitude. b. What is the new altitude at the end of this flight?
