The real trick there is finding the GPS-NAV. I couldn't find one and
ended up with a Colibri I got from Paul. It seems it will work quite
well with my S-NAV, at least on my desk. I have yet to fly with all
this. If I run across a GPS-NAV for a good price I might pick it up
but without the GPS-NAV all that seems to be missing is the goal
altitude and you also don't have the final glide around a turnpoint.

How often is the goal altitude really needed? Here, unless you're on
your way to the last turnpoint or home you want to stay in the best
lift which is usually above a certain altitude. It often has little to
do with the ground elevation of the goal and more to do with the
airmass. So you'd have to manually enter your "floor" altitude anyway.
If you have something like GNII on a PDA you have the final glide
around a turnpoint based on the GPS data and air and GPS speed-to-fly
info on the S-NAV.

The bottom line is all this stuff can only tell you what's been going
on behind you and not what's going on with the airmass ahead. It still
comes down to the pilot.

I seem to have gotten off track but I didn't see anything in the S-NAV
or manual about a waypoint database. Mine is the current version 7.9.
Maybe that was dropped from earlier versions since it is available in
the GPS-NAV.

Hi,

The L-NAV does everything an S-NAV does, except that the S-NAV has a
waypoint database and you can create tasks. There may be a few other
features, but that was the main thing. When the GPS-NAV is connected to
either of them, you use the waypoints and tasks in the GPS-NAV, so there is
no need for them in the S-NAV. So at the end of the production they didn't
sell many S-NAVs - only L-NAVs. But there is nothing wrong with using an
S-NAV with a GPS-NAV.
