Is anyone still interested in CuSoft "Polar Explorer" program for PC?

Branko,
Do you know if it will run correctly under the "DOS Window"
of various flavours of Windows, or does it need a pure DOS
environment ?

| Hello,
|
| Sme 10 years ago I wrote a program for DOS named "Polar
Explorer" - designed
| for analyzing both theoretical and practical aspects of
glider performance
| in any conditions. The program was advertised in the
Soaring magazine for a
| couple of years by CuSoft Research Inc., and some 30 odd
copies sold for USD
| 99 each.
|
| If anyone is interested in this program (see the short
description below), I
| will consider posting it on my current company's website:
www.trimill.com
|
| Sincerely,

| SHORT DESCRIPTION
| ===================
| Polar Explorer is designed to answer many `specific`
questions about glider
| performance. As a result, you can use it for many
different purposes. The
| following are a few examples of what you can do:
|
| Complement the books and articles on glider performance
and soaring tactics
| by working out practical examples.
|
| Find out the `optimum circling technique` for any glider
at any altitude and
| wing loading.
|
| Plan and analyze cross-country flights and final glides.
|
| Optimize configuration and wing loading in any weather
conditions.
|
| Apply `generalized speed-to-fly theory` to maximize
cross-country
| performance when using ridge lift or waves.
|
| Compare circling and cross-country performances in
addition to comparing
| polars.
|
| Design and test speed rings and final glide computers, for
any altitude and
| wing loading.
|
| Enter and analyze any glider polar that you come across.
The glider polar
| library that comes with the program already contains 150
polars (see below).
|
| If you are contemplating any modifications to your
sailplane (e.g. adding
| winglets), you can use Polar Explorer's advanced features
to estimate the
| performance gains.
