I can not understand those complicated formulas cause my mind has room enough only for a couple of “precision approach to girls” procedures. Using simple words:
Mach number is a function of true airspeed and air temperature whereas IAS is largely a function of true airspeed and air density. Consequently, when an aircraft descends at a constant IAS, the Mach number reduces but when an aircraft descends at a constant Mach number, the IAS increases…
