                Hello,

I wanted to used the wind calculation and wind direction on the HUD.
So after the fly i take the tlog recorded and try to extract the wind parameters.
But cleary it is not the same so i suppose that the data store are
some raw data and there is some calculation to show real wind value to
the HUD.
Where i can find this calcul ?

Thanks for you help

do you use an airspeed sensor?

then the airspeed and direction is derived from the airspeed sensor. and will just be a field in the tlog.
