Interesting, where is the windvector inverted? On the S100 compared to LK8000?
None of the V7 drivers take Windinformation from the LXNav devices. The only driver taking wind deliverd by $LXWP0 sentences is the LX dirver.
As far as I remember, the LX devices show the angle relative to the glider heading where the wind is comming from. But the manual is quite unclear about the wind direction http://www.lx-avionik.de/wp/download/manuals/LXS8xS10xManualEnglishVer0626.pdf Also the LXNav dataport spec. does not specify the wind vector reference delivered by the $LXWP0 sentences (relativ to heading, blowing from, going to).
LK8000 calculates the wind direction where the wind is "blowing from" referenced to geographic north (e.g. 225° = wind comming from SW). And thats what I would expect to be deliverd by the instrument as well, since it is used most commonly this way.
We don't have a LXNav device So I need an NMEA log of flights with significant wind to verify/implement this.
