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.
