Average Mach Number Calculator

The average Mach number in flight mechanics represents the ratio of an aircraft’s average true airspeed to the speed of sound in the surrounding air. It is a dimensionless parameter crucial for characterizing an aircraft’s speed, particularly in high-speed and supersonic flight regimes. The formula to calculate average Mach Number as follows:

Where:

  • Vavg is the average velocity in m/s
  • aSL is the sound of speed at sea level in m/s.
  • Mavg  is the Average Mach number.
