This item computes trueairspeed (TAS) and density altitude, based upon the factors above. Also,this feature determines winds aloft — the wind direction and speed — anda head wind/tail wind component, based on true airspeed, aircraft heading(HDG) and ground speed.Touch To SelectGround SpeedTouch To SelectIndicated AltitudeDALT, TAS, andWinds StatisticsTouch To SelectBaro PressureTouch To SelectCalibrated AirSpeedTouch To SelectTotal Air TempTouch To SelectTrack ValueTouch To SelectHeading ValueFigure 15-33 Utility DALT/TAS/Winds Page
