ESDU 78017 gives graphs showing the variation of true airspeed in m/s with equivalent airspeed in m/s@ pressure altitudes in m and Mach number@ and the variation of true airspeed in knots with equivalent airspeed in knots@ pressure altitudes in feet and Mach number@ both in an International Standard Atmosphere. The graphs complement those in ESDU 69026 which includes data on the variation of calibrated airspeed.
