An aircraft is flying straight and level at an altimeter reading of 10,500 ft (with the altimeter set to a reference of 29.92"Hg) and an outside air temperature of 32F. If the pitot-static system on the aircraft measures a dynamic pressure of 12.6 lb/ft 2 , what is the indicated airspeed? What is the true airspeed? What is the Mach number of the aircraft?
