Rivet Gun, guess I am the only one then that thinks you are correct. Seems the responses have all avoided your original question though. For the others who replied, here’s Rivet Gun’supposition from his original post,
“Now I thought that at a constant flight level, the relationship between IAS and Mach number is independant of temperature. So if you maintain a constant flight level and constant IAS, you also fly a constant Mach number even if the air temperature changes.”
The thread then departed to address other aspects, such as mach vs tas, EAS, compressibility, formulas…..
If Rivet is incorrect, then, will anyone go out on a limb and say what direction will the IAS (assuming no error correction/position error) or CAS will take if you fly at a constant mach and flight level and the air temperature gets colder?
