[br]Hallo,

I have done forther investigation on that and I find if static pressure is multiplied by 100.( may be it is used in Pa) the TAS values are as expected. So the code in devXCVario.cpp should be:

[quote]
double dyn_press, static_press;
  if (ReadChecked(params[8], static_press)
      && ReadChecked(params[9], dyn_press)) 
  {
    // Static && Dynamic pressure in hPa
    pGPS->AirspeedAvailable = true;
    pGPS->IndicatedAirspeed = sqrt(163.2653061 * dyn_press / 100.);
    double qne_alt = StaticPressureToQNEAltitude(static_press*100.);
    pGPS->TrueAirspeed = TrueAirSpeed(pGPS->IndicatedAirspeed, qne_alt);
  }

[br]Hallo,

try to use XCVario driver on my Kobo LK8000 7.4.15. 
TAS airspeed indication (km/h) is wrong, IAS airspeed indication is correct. 
I logged some records XCVario sends:

Best Regards.
