Hi All I have experienced XCSoar report grossly inaccurate wind values. Wind speeds of > 100km/h, coming from the completely the wrong direction. This happens with wind settings on "auto, both". I have seen it quite often, but not on every flight. If I play with settings during flight, I can sometimes fix the issue. Setting wind to "auto, circling" for a while seems to help. If I can "tame" this issue, the wind calcs are fast and accurate for the rest of the flight.
This is a photo of a NMEA log file replay on my Dell Streak which shows the problem: http://users.zsd.co.za/~ian2/xcsoar-bug/2014-11-20%2009.24.36.jpg The wind speed is indicated > 100 km/h, it should read about 25km/h. This is an hour and a half into the replay. I also setup info boxes to show true airspeed and ground speed. I searched the bug lists and I found this ticket which appears to describe my problem: http://bugs.xcsoar.org/ticket/3062 I have added comments to that ticket with a link to a NMEA log file and that photo. Unfortunately nobody has claimed ownership of this bug and there have been no updates for over a year. So I posted this here least somebody sees this and is inspired to provide man hours to fix the problem. I do a lot of ridge and wave flying where circling wind calcs do not work and I loath playing with PDA settings in flight. (Definitely not a good idea when ridge soaring!). So I am keen to help get this bug fixed. Thanks in anticipation!
