An airplane weighs 180 kN and has a wing area of 160 m2 and a mean chord of 4 m. The airfoil properties are given by Fig. 7.25. If the plane is designed to land at Vo = 1.2Vstall, using a split flap set at 60°,
(a) What is the proper landing speed in mi/h?
(b) What power is required for takeoff at the same speed?
