Never heard MACH pronounced Mack always heard Mock. Must be a British thing. Good explanation.... USAF veteran.

Sorry to disagree, but anyone can get me wrong.
Mcrit is the airplane MACH number at which the 1st dot of a sonic flow appears on the upper wing surface. At this MACH number, there is not any shock wave yet on this portion of the wing.
The onset of the 1st shock wave occurs at a MACH number called Mlim or the limit MACH number.

Hi there, what is critical mach number useful for, under which circumstance do we need it for?

[jcc]

Does the airflow reach the speed of sound because the air particles are attached to the wing?

[ErimTuna]

Two methods to increase the critical Mach number are: thin aerofoils and sweepback of the wing.
