Which outcome occurs when an aircraft's airspeed approaches critical Mach, violating compressibility corrections within the Euler equations?

💡 Explanation

Shock induced airflow separation results because exceeding critical Mach causes the pressure gradient to amplify via the Prandtl-Glauert singularity, triggering boundary layer turbulence. Therefore, separation appears rather than increased control authority, because turbulence modifies lift.
