+mach trimmer
I understand that aircraft have an overspeed warning or clacker. But correct me if I'm wrong...you could still have a high speed BUFFET without it going off.
Since the air is accelerated over the wing further with increased angle of attack...you could have a mach buffet well below your max mach. In other words, the overspeed sensor does not know your angle of attack, only your mach #.
High speed buffet occurs as the shockwave moves rearward when the air becomes turbulent and separtes as airflow goes from transonic to subsonic flow. (Bernoulli)
So my next question along similar lines is. Which boeing aircraft today have a mach trimmer? I believe the 747 and 727 do not.
What about Airbus?
Thanks again
