A propeller-powered aircraft of mass m = 2000 kg is flying in straight and level flight at an altitude h=2500 m. At some point, the airplane loses its only engine and the pilot engages in a quick calculation to estimate the maximum horizontal distance he can cover, assuming no wind throughout the glide. The airplane lift curve is CL = 0.15 + 0.22α (α in degrees), the stall angle of attack is αS = 11o and its drag polar is CD = 0.03 + 0.08 CL2. What is this maximum distance he could fly with an optimal glide?
