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.

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 , 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); }
