Abstract : The various mechanisms by which loss of consciousness can be brought about are discussed both from the pathologic and physiologic viewpoints. The incidence of syncope among aircrew as revealed by various studies is presented. An analysis was made of 88 cases of syncope among aircrew who were evaluated at the USAF School of Aerospace Medicine during the years 1966 and 1967. Out of these cases seven had occurred during flight but in none was syncope attributed to any factor in the flying environment. The study reveals that most of the cases (65) occurred in persons below 40 years. There seems to be no correlation between the experience (number of hours flown) and the incidence of syncope. It was noted that in over 60% of the cases, there was no history of earlier episodes of unconsciousness. The percentage of cases recommended for flying did not differ much between those who had no previous episodes and those who had one or two episodes.
