摘要:The introduction states that this book is written for the group of young people from which the future flyers must come, for the mothers and fathers of flyers and for the reading public. It provides a brief explanation of the physiological basis for many of the stresses to which the pilot is subjected during flight and discusses the rationale of tests performed to determine the pilot's fitness to withstand these stresses. Within its pages it includes chapters on physical requirements and body reserves, the central nervous system, the eye, the ear, equilibrium, "the neuro-physical composition," and the respiratory, circulatory and digestive systems.
