7.38 The pilot of a hang glider with a total mass of 110 kg and wing area of 14 m is going to glide from a height of 300 m to sea level. The aircraft has CD. = 0.019 and K = 0.07, CL max = 1.2. a. What is the maximum flight time that the hang glider can be airborne? b. The goal is to be airborne as long as possible; what must be the glide angle? C. How far (horizontal distance) the aircraft will glide from this point before touching the ground for this glide program? Assume that the air density is constant throughout the flight at 1.225 kg/m. 7.38 The pilot of a hang glider with a total mass of 110 kg and wing area of 14 m is going to glide from a height of 300 m to sea level.
