Why *would you want a PDA when you have an SN10?

What customers have told us is:
- I want a moving map ALWAYS displayed for alternates and airspace
- I want to see alternates without page-fiddling
- I want to use the SN10 for everything EXCEPT the map

This is how we arrived at the current NMEA outputs;
to support the common customer requests.

This moving map business is over rated and puts your eyes inside
the cockpit.

For those that want to see this info all the time, its
less time heads-down with the PDA map display

You done good on the SN10 wind program, Dave.

Thanks !

PS: See JJ, some of these guys are a whole lot more nervous
than you ex-fighter-jocks, so they need to have this info
always available rather than just checking when appropriate ;-)

Dave, I still don't get why you don't provide the TAS data on NEMA.
You seem to say that pilots, or the PDA software, can compare the
calculated wind from the differnet devices but you are tying the hands
of the PDA software a bit and either it has to do non-TAS enganced
wind calculations or it has to take the SN-10 calcualted wind data.
Why not let the PDA software see the same TAS data you are using? That
does nothing to take away from the good wind calculations the SN10 is
doing internally. Again I can see why Naviter would prefer to do their
own raw wind calculations - and as a user I'd prefer the PDA software
be using the same basic algorithms regardless of the source I'm
conected to.

To Andy's point I do like to compare different wind calculations. But
in my case I am checking what my Cambridge 303 is showing vs. what
SeeYou is showing (enhanced from the C302). Here there is a common
point of failure in the TAS data (unlike Andy's setup). I suspect many
pilots are competently unaware of what is actually going on between
their GPS/flight computer and PDA software for wind calculations. What
would be useful is if Naviter (and other?) software vendors would
explain more clearly the sources/behavior of wind calculations, Mc
settings, ballast settings, etc. depending on what device they are
connected to. Andrej, if that documentation exists shoot me down
now...
