A high-altitude, propeller-powered aircraft has been designed to loiter at an altitude of 30,119 feet. Calculate the aircraft's Mach number at the cruising altitude if it is being flown in conditions to maximise its endurance. Pertinent specification: Aircraft weight: 1,141 kN Wing planform area: S- 317 m2 Wingspan: b = 74 m Wing efficiency factor: e 0.61 Parasitic drag coefficient: Cp - 0.039
