JSW Calculators

[Jules]

Hi,
Newbie pilot in the UK and I want to start (to learn and master!) soaring
and maybe in a couple of years XC.
I think a JSW for my K8b will be useful ? ? comments invited.
But where can I get one from . . .
TIA
Julian

If your destinations is out of site under your nose you can reach it, if you
can see it you cant!

Get a copy of Helmet Reichmann's Cross-Country Soaring. It has a good section
on how to make one your self. Reichmann's books are great additions for any
beginning x-cross pilot's library.

Hate to show my ignorance but what is a JSW calculator?

I got it a few years ago, but forget from where. I just now posted it for you
on my site at www:mymedtrans.com/personal.htm

Its always a good idea to do a google search of the newsgroup before
you ask a basic question like this. If you had done this you would
have found that just 2 months ago the same question was asked with a
number of good answers provided. One of the replies was mine,

Depending on how adventurous (and mathematically included) you are,
you might consider generating your own circular calculator. (Stocker
glide computer). Reichmann has a fair description in his classic
Cross-Country Soaring. I presented a paper at the 1991 OSTIV that went
into some more detail on the construction and added an HP Basic
program to generate the overlays for a given glide polar.

While the HP Basic is long out of date, the principles remain the
same.

You can find the paper and program info on Guenther Eichhorn's Soaring
Server,

unde the title Ostiv91.zip, down near the bottom of the page.

Hi Jules,

I have a JSW here from my Ka8 days.... Will sell for $10 plus shipping
if you're interested.

a circular, pre-silicon, slide rule glide calculator aka a
prayer wheel.

With respect Bob, you did not answer the question I asked.

Your answer and *most* of the others in that thread are about making your
own. If I wanted to do that I would have asked that question.

The other URLs and sources quoted in that and other threads I have found
were not appropriate to my needs hence I asked the question - where can I
get one from?

My problem appears solved however since Kevin has offered me one which I am
contacting him about.

Regards
Julian.

RD Aviation in the UK has some JSW Calculators. Pete Purdie has
probably the only commercially available stock left. I found him him
to be very helpful. He can be reached at:
Hope this helps. Gene

A circular slide rule developed (invented?) by John S Williams (rather like
the MacCready Ring being invented by Dr Paul McCready). Probably best
considered as an early form of glide computer.
