A turbojet airplane of mass m = 4000 kg has a drag curve D = 0.75 v2 + 0.04 W2/v2 at sea level (ρ = 1.225 kgm−3) and the engine is producing a thrust T = 20000 N,. What is the descent angle if the airplane is flying at a speed v = 100 ms−1?

An airplane powered by a single turbojet engine loses its only engine at an altitude h = 2000 m above sea level, and the pilot decides to glide the maximum possible horizontal distance. How far will it glide if the mass is m = 4000 kg, the parasitic drag coefficient is CD0 = 0.065, the Oswald factor is e = 0.90 and the wing aspect ratio is AR=20?

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?
