Mach number to IAS..HELP
An aeroplane cruising at FL 350 in ISA conditions commences its descent and holds Mach 0.76 to an altitude where its speed is 300KIAS at which point the pilot selects airspeed hold for the remainder of the descent. Using a plot of True Airspeed at altitudes between top of descent and 20,000 ft determine the altitude where Mach Number and Indicated Airspeed correspond.
