1st ed., 1942. 112 pp., numerous diagrams. D.j., 22 x 15cm. Small repair to rear of d.j., o/w V.G.+. Air Navigation is the art of conducting a plane through the air from one place to another regardless of whether the ground beneath is visible or recognisable. Published during the Second World War in 1942, this book was written specially for air-crew cadets of the Air Training Corps and the many deferred-servicemen who were requiring a knowledge of the principles of air navigation. The work was designed to cover the A.T.C. navigation syllabus in one volume but at times it goes beyond the requirements of the syllabus. With diagrams and exercises. Scarce in dust-jacket.
