Hi rudderrudderrat,
Thanks a lot for your explanation. Short but i have to say precise and clear! There's no better way to do it!
I just have one more doubt in my mind. I understand that a variation in Temperature will affect both TAS and LSS so, at the end, the result MACH will not vary because both factors vary at the same time of the same (i hope i don't say something wrong now..) amount and they cancel themselves out by their own. So temperature is not a factor. This i got..
Now. Taking back for a moment the temperature of a given air mass a change of this, as you said as well, will affect density altitude.
But now my head crashes again. A change in temperature which is followed by a change in density does not change as well the pressure of the air?
So here now i come back to my problems. How can it be possible that we ALWAYS find the SAME pressure at the SAME FL which allows us to make the crossover from CAS to MACH if temperature's changes affect as well pressure?
Thank you again guys. I'm sorry if maybe i ask something that should be obvious.
Regards to all of you,
