Manual for pilots and aircraftsmen based on the curricula of the Army Air Corps and the Naval Air Service. Intended for student fliers, for anyone actively or theoretically interested in the basic principles of aviation. Should serve as an introduction to serious study, plus a tip off to aspirants as to the necessary qualifications. Not for boys, as the author assumes a certain degree of familiarity with technical processes and vocabulary. From a careful study of the principles of aeronautics to an analysis of plane structure, he goes on to instruction in meteorology, in traffic control, etc., etc. Sound. Authentic.
