(a) Show that for unpowered flight (for which the lift, drag, and weight forces are in equilibrium) the glide slope angle, θ, is given by tan . (b) If the lift coefficient for a Boeing 757 aircraft is 16 times greater than its drag coefficient, can it glide from an altitude of 30,000 ft to an airport 60 mi away if it loses power from its engines? Explain.
