While there is a universal understanding that aircraft move at incredible speeds, surpassing an aircraft's imposed speed recommendations can produce hazardous consequences. To provide pilots with visual awareness of current airspeeds being traveled at, devices like airspeed indicators (ASI) are typically used. Depending on aircraft model, various measurement conventions can be used to calculate airspeed and range from indicated airspeed (IAS), calibrated airspeed (CAS), equivalent airspeed (EAS), and true airspeed (TAS). However, to distinguish airspeed on high-speed aircraft such as jets and airliners, a machmeter must be employed. Indicating airspeed as a Mach number (M), machmeter instruments project the ratio between an aircraft’s true airspeed (TAS) and the speed of sound (LSS) when measured by a pitot-static system.
