Dancing With The Wind

Dancing With The Wind

General Description

The first book dedicated exclusively and exhaustively to slope and wave flying, with the very first aviation details of Hydraulic Jumps, how to identify and use them. New information on the intelligent use of Oxygen.

Published both in English and French, this is the first Manual of Sailplane Slope and Wave soaring techniques. Everything you need to know to fly using the wind, happily and safely.

All about the wind, why, where and how, local breezes, convergences etc.

Explaining tricks and tips of slope soaring and real dangers, from the first slope flying records by Karl Striedieck in the USA until today.

All about the theories of the formation of waves, from Queney to Scorer and Wurtele, including atypical waves and Hydraulic Jumps (Bidone's jump). Specific techniques to use lee waves, especially non conventional ones, including wake waves. Narratives from pilots having survived a potentially fatal accident.

Theory and application of the “Speed–To–Fly” concept in strong winds. Review of structural limitations and narratives of pilots having exceeded these limitations (after having bailed out).

Review of all health issues linked to mountain and high altitude flying.

Intelligent use of Oxygen: new regulations and reality: The rules of in–flight experiments on Electronic Delivery Systems for oxygen (EDS®), all the secrets revealed, then recommendations.

How to maintain “zero tolerance of hypoxia”. Altitude of the Pilot in Command: “Good Airmanship”.

Author: Jean–Marie Clément, together with Dr. Heini Schaffner for oxygen medicine and Dr. Gilbers Bouteiller for general medicine.
Pages: 304 pages, full color, 211 high definition photos and color drawings. Copyright 2015.
Dimensions: 8.5 x 11.0 x 0.91 inches (216 x 280 x 23 mm)

“Imagine that you are walking through a large, dark and well known room – and that you do so with ease because you are familiar with its invisible contents.

Or that you are flying through the atmosphere, whose transparent air hides its invisible movements – again doing so with ease in normal, familiar conditions.

But now imagine yourself running through a dark room full of energetic, moving equipment, looking for treasures to catch on the run: after a few steps, hopefully before you hurt yourself, you realize you need a map and a lamp, to avoid the dangers and navigate towards the treasures.

This book reveals to you the invisible treasures of the atmosphere, explains its promises and its dangers and teaches you how to enjoy them.

Even if you never left your armchair, you will wonder at the hidden beauties and incredible energies of our sky and you will learn how to read its state and ride its magic carpets.

But, as the author tirelessly warns you at every new chapter of this marvelous book, do not enter this environment without thoroughly understanding it, or you may be severely punished –flying thousand miles without an engine, at Everest’s altitudes over unlandable deserts, is now possible but cannot be improvised – you need to fully comprehend the aerial phenomena, the flying equipment and, above all, yourself, your physiology and your psychology.

My personal flying experience barely allows me to fully appreciate how deeply, how passionately the author is sharing his wide, hard earned knowledge about flying gliders in extreme environments: Jean–Marie provides us with a “beautiful map and a strong lamp” to safely explore one of the last hidden jewels of our fantastic planet – for this gift not only the gliding community but every curious, nature loving person will be forever indebted to him.” – Alvaro de Orleans-Borbón

Review

“Opening this book is like discovering a buried hoard of precious jewels. it is printed in full color and Jean–Marie Clément has made good use of this to illustrate the text with beautiful photos and clear diagrams on almost every one of its 300 pages; but the real value is in the wisdom and experience that it contains.

Although Jean–Marie has been soaring at top level for 50 years, few UK pilots are familiar with him, because his soaring experience has been mainly in France and Italy and latterly in Argentina as well. Holding 27 French records and six World records allows him to write with great authority.

As befits an author whose playground has been in the hilly and mountainous parts of the world, this book covers almost every type of soaring, except for the classic flatland thermal soaring that we typically enjoy in southern England. There are chapters on slope soaring, mountain thermals, various types of wave lift, and wave flying techniques. Further chapters tackle aspects of long distance flying at high altitude, including human factors and using electronic oxygen breathing systems.

This is a book for experienced pilots who are ready to stretch themselves by flying for longer and going further and faster using some of the most exciting and challenging soaring opportunities on the globe. Jean–Marie is careful to stress what you must do to mitigate the inevitable risks of flying close to the hills and mountains and over such inhospitable terrain. He emphasizes this with details of accidents where even skilled and experienced pilots have broken their gliders, or worse.

For me this is a “must-have” book; however, for some reason I didn’t find it an easy read. Occasionally the content is very technical. in some places the translation from French makes the meaning difficult to discern. Balanced against any shortcomings is the wealth of knowledge and experience, not only from the author, but also from other world class pilots, including our own John Williams, all assembled into a single volume. How did we manage without it?” – Phil King, Herefordshire GC
