Hi, you are right, it is a float, but it wont work even if i set a float value. I set three cloud values first. is that why no turbulence is showing? I guess if the turbulence is set i will see the values in the weather window as i do when i set my cloud? This is what i have, cloud works but nothing else. //Set weather XPLMSetDatai(XPLMFindDataRef("sim/weather/cloud_type[0]"),cloud0); XPLMSetDatai(XPLMFindDataRef("sim/weather/cloud_type[1]"),cloud1); XPLMSetDatai(XPLMFindDataRef("sim/weather/cloud_type[2]"),cloud2); //0-1 XPLMSetDatai(XPLMFindDataRef("sim/weather/thunderstorm_percent"),0.7); XPLMSetDatai(XPLMFindDataRef("sim/weather/wind_turbulence_percent"),0.8); XPLMSetDatai(XPLMFindDataRef("sim/weather/rain_percent"),0.6); XPLMSetDatai(XPLMFindDataRef("sim/weather/wind_speed_kt[0]"),0.5); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/wind_speed_kt[1]"),0.5); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/wind_speed_kt[2]"),0.5); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/turbulence[0]"),5.0); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/turbulence[1]"),5.0); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/turbulence[2]"),5.0); //int kts XPLMSetDatai(XPLMFindDataRef("sim/weather/rate_change_percent"),1.0);
