An aircraft weighing 65.2 kN when empty has a wing plan form area A of 62.3 m^2 . It cruises at a velocity of 900 km/h and a 4.0 degree angle of attack and altitude of 8500m. Also, the wing characteristics of the airfoil are shown. (a) Determine the allowable weigh of the cargo (b) and if the wingspan s is 20m determine the induce drag coefficient C_Di.
