Wind speed and direction

Hi pilots,

I know this subject has been discussed in the past but I am not sure
if this particular issue has come up. I run a CAI 302 which drives
both Winpilot Pro and a 303 head. The wind speed and directions are
often differing by large margins on these two displays even though
they must be looking at similar information. This is true even after
turning such that both displays should be completely "updated".

What are your thoughts on this subject or can you direct me to the
archives where this question may have been already answered?

Also on the subject of Winpilot, myself and others have pushed on
Jerry to provide a navbox with speed-to-fly data. He is apparently
unwilling to do this even though the program must be calculating it.
I understand the reasoning behind not chasing the instantaneous STF
number but I often wish I knew exactly what that number was. Other
programs such as GN II do provide this number. If other WP users push
on Jerry as well maybe he will put this navbox in. Thoughts?

Thanks and fly safely,

Bob Caldwell
