A Simplified Chart for Determining Mach Number and True Airspeed from Airspeed-Indicator Readings

reportActive / Technical Report | Accession Number: ADA801325 | Open PDF

Abstract:

The determination of flight Mach number from measurements of indicated airspeed and pressure altitude is shown to be relatively simple and leads to direct and accurate computation of true airspeed. A simplified chart is presented for determining flight Mach number and true airspeed for a range of values of indicated airspeed, pressure altitude, and air temperature. A table of standard atmospheric values is included.
