Default 302 wind calculation

Hi Evan,

Your feedback is so different from all other Cambridge 302 user feedback
I've received that it makes me wonder whether your 302 is out of calibration
in some way. *Does it show accurate airspeed while in flight?


Yes, IAS right on the money. OAT is correct and the TAS output to the
PDA is good. XCSoar was doing very well calculating wind in "zigzag
only" mode using 302 output.

It's got current firmware, it's been back to the factory for barograph
cal and updates in the last year, I am assured it works as designed...
even after I explained to Dave Ellis about the 65 mile ridge run with
relative wind indicator 180 out of whack (flew to end of ridge, did a
wing over, got back on the ridge the other way without a wind
update). When I called CAI/R-Track about these specific issues, all I
got for a response was "... why don't you call Richard @ Craggy
Aero." Which I did. I sent flight logs with annotations. Nothing
came of this.

If anyone would like to send me a 302 to swap out and test, I'd be
happy to do so. I'd spend money to fix this if in fact someone could
determine what needs fixing.
