Years ago I learned that, for a 40ish to 1 ship, you could hold out two
fingers at arm's length such that the top of the fingers rests on the under
side of the horizon. Anything visible below the second finger is reachable
at your present altitude. Give it a try! I suppose 3 fingers would work
just fine for a 1-26.

About a month ago while flying a borrowed glider, my Streak batteries died
and I had no GPS to tell me if I could glide back to the home base. I was
mortified. Contemplated pulling the dive brakes and landing at the airport
I was over, because 30+ miles with no glide computer and a 3k AGL day must
be impossible. I am kidding. The reality is that when I have lost GPS,
like this flight, I just fly a bit more conservatively because long
distances are hard to judge, so I use closer points that are maybe 10-15:1
away to gauge progress.

As you have already discovered, you don't need a GPS or a Chart or a
wiz-wheel. You need a sensible head and to pay attention to your
surroundings and what the landmarks are doing as you fly towards them.

I can't eyeball a 40:1 glide and know I'm going to make it to that obscured
place on the horizon, but I can sure tell that the field 10:1 away is
sliding under the nose. I came sailplanes from hang gliders, where you
rarely even consider using a chart or relying on a glide computer for glide
calculation so concern with the glide computer started out very low for me.
I actually fly with two in my glider. An L-Nav and a Dell Streak. They are
set up differently and rarely agree perfectly on glide. That's useful since
the Streak is my pessimist and the L-Nav is my optimist

Definitely get yourself a GPS. If nothing else, being able to review your
logs in See You is an amazing tool for learning from your own decisions.
You'll also gain an appreciation for the performance or lack thereof of your
glider as you can see in real-time how you are doing towards a fixed point.

I do find that the GPS enables me to think farther ahead. If I'm 2000 above
a conservative glide to an airport, I'm not spending as much time looking at
closer alternatives. This is probably more of a high-performance glider
issue than a 1-26 issue, but freeing processor cycles for more important
activities is a good thing. If you think you can reach Airport X, and you
have 5 landable fields in between you and Airport X, you'll be more
comfortably focusing on the clouds or looking for birds or other indicators
of lift. You get to focus on the soaring more as you've got an easily
monitored data point to gauge your progress.

Sounds like you are doing it right though. Head out of the cockpit, field
to field. Fun stuff. Don't be afraid to augment that judgement with tools
that we have available.

I am fairly green had my PGL for about 3 years now.



Been venturing into cross country, have done my first flight out to
another airport, and last weekend, an out to that airport and return,
about 30 miles round trip (in a 1-26, no ridges, it's all flat Florida).
No it's not very far, but at least I am not just circling the airport for
hours, and my enjoyment of soaring has been taken to a new level.



However, I was told recently by an older experienced pilot that using a
GPS is "not the correct way to do it". Instead I should be thinking "can
I get there... now can I get there... can I get there...". I understand
this ideology, but I am pretty sure nearly everyone is using GPS these
days.



So, does this mean I should not use modern navigation technology? I know
how to plot a cross country flight on paper of course, and required
altitudes to the next safe landing area.



Does this mean I should I actually be drawing circles on charts, carrying
a slide ruler to calculate arrival height at various distances, and
mechanically doing everything my GPS is doing for me? This means I am not
looking for traffic, or thermalling but instead flipping through charts
and playing with a slide ruler or E6B, and my eyes are not outside the
canopy.



Anyway, please enlighten a new pilot, I am listening intently. if I
should not be using a GPS at this point I'll go without.



Thanks
