Radio Navigation and IFR. The Basics - Volume 1

This book is part of a 3-volume collection devoted to radionavigation. It is aimed at those wishing to improve their knowledge of radionavigation. It can also be used as a reference by instructors to illustrate their courses. With the exception of most of chapter 1, which is devoted to mental arithmetic, this book will be very useful to any private pilot.
In this volume, we will study:
- mental arithmetic;
- the materialization of position in space;
- the different methods of changing axis;
- and the classic means of radionavigation (VOR, HSI, DME, ILS, ADF, RMI...).

This knowledge will enable us to study IFR trajectories and GPS in the next volume. Even though GPS is becoming increasingly important, as evidenced by the growing number of RNAV procedures, it remains essential to know how to use these classic radio navigation methods. Not only are they still widely used today and, indeed, still part of a private pilot's training program, but their study through CDI, HSI and RMI is useful, as these indicators are also used by GPS. It is also with the help of these same indicators that we can adhere to the prescribed trajectories, the scrolling map displayed on a screen being present only to provide additional information.
The use of these classic radionavigation tools is explained, with emphasis on their materialization and on a few simple basic principles which, once acquired, will make it easy to solve any problem.
Perfect mastery of radionavigation, and the materialization of the aircraft's position in space, require serious training, first in the simulator, then in flight - training which is consequently costly. This book will help you acquire the basic knowledge you need, so that you'll be more available, especially on your first flights.
The presentation, illustrated by numerous diagrams, is designed to be as simple as possible, sometimes using analogies. In addition, numerous corrected exercises will enable the reader to check his knowledge and make the course his own by developing his own experience.
The other volumes are dedicated to:
- for Volume II: IFR and satellite navigation;
- for Volume III: flight director, autopilot, EFIS, onboard weather radar, stormscope, augmented vision equipment and HUD (Head-up Display).
