New Volumes FOR THE SHELVES
THIS 234-page book with 50 illustrations covers in a logical way the subject of Aerial Navigation, or, as the author terms it, “Avigation.” Well arranged as to subject matter, and amply indexed, it meets a timely need. The aim of the book is to draw a proper balance between the three major branches of air navigation, Piloting, Dead Reckoning, and Celestial Navigation, and this aim is clearly stated in the Introductory chapters.
