WINPILOT + ILEC SN-10 + VOLKSLOGGER

Having good heading info only when flying wings level is not that big a
problem, since the present SN10 algorithm works fairly well when one is
turning. One could just switch back to the present algorithm for turning
flight. Maybe that's what the Zander does (a previous poster said he didn't
understand how the Zander, which uses a heading sensor, can calculate wind
when the sailplane is banked).

If an accurate aircraft heading sensor were added to the SN10, thus
completely defining two of the vectors in the "wind triangle", this would
not be necessary. One lives in hope...





For $300 you can add a fluxgate compass that will communicate via NMEA...
Fixing the software to use it would be up to you.

Of course, the heading information will only be good when you are flying
straight and level...
