Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

That’s the speed your airspeed indicator shows based on ram air pressure in the pitot tube. The tailplane (horizontal stabilizer) at high Mach can also develop shocks or experience disturbed airflow from the wings. Ailerons can suffer from a phenomenon called “aileron buzz” or control reversal at high Mach.

It can also disrupt sensors needed for flight safety, like the pitot tubes. If ice blocks a pitot tube, your aircraft’s instruments will provide inaccurate airspeed readings. Most aircraft are equipped with a pitot heater to prevent icing in the pitot tube.
