RESUMO
A set of the objective quantitative parameters characterizing a pilot health status in a generalized form is required to manage the medical examination system. The medical and statistical data are proposed to be used. The major indices of health status of a group of pilots (public health) are: 1. Probability estimation of threat to space mission safety due to a sudden incapacitation of a pilot; 2. Evaluation of medical disqualification rate per mile of pilots tested; 3. Flying longevity of the pilots evaluated as an average duration of forthcoming flying activity; 4. Prevalence of diseases and factors of their risk determined from the standardized criteria. The methods of obtaining the mentioned and some other quantitative data on pilot personnel of the former Soviet Civil Aviation are discussed. It is indicated that at present the level of health threat to flight safety conforms to the general safety standards.
