Calculate Mach number from airspeed and altitude, or calculate the airspeed for a given Mach number at a specific altitude.
Mach compares aircraft speed with the local speed of sound. Below Mach 1, pressure waves can move ahead; above Mach 1, they collapse into a trailing cone.
Aircraft speed
V = 600.0 m/s
Local sound speed
a = 299.5 m/s
Trailing Mach cone
Disturbances stay behind the aircraft.
Mach angle
μ = 29.9°
