Description
This book has been written for practical navigators. Its purpose is to provide a complete course in Astronavigation, with only essential references to the mathematical and theoretical aspect. I feel sure that few air navigators will have time to study the less practical methods by which the technique may be applied, some of which involve plane or spherical trigonometry, and are of interest only to a few specialists.
A certain knowledge of basic principles is, of course, necessary as a foundation, if the practical work is to be fully understood. Such principles have, therefore, been included, together with a certain amount of elementary astronomy which will help the navigator to appreciate the nature of the heavenly bodies and their movements.
