[The assessment of a state of tension in a pilot by bloodless biochemical and immunological study methods].

Immunological and biochemical study of salivary liquid was carried out in order to estimate the tensity state of a pilot in operating conditions. These studies were conducted in the period of flight-development tests during man-compartible estimation of the cockpit of a light aircraft. The existence of natrium and secretory "A"-immunoglobulin in saliva in combination with psychophysiological parameters of tensity made it possible to reveal different levels of tensity proliferation (slight, moderate, strong and very strong). In the process of flight tests a correlative dependency was found between biochemical/immunological indices of salivary liquid, results of psychological testing, and informational/navigative loads of a pilot. This dependency was used during laboratory testings which were included in the complex of researches on man-compartible characteristics in the system "pilot-cockpit-aircraft".
