Over the past decade, the international civil aviation organization (ICAO) has been actively engaged in the development and subsequent implementation of new highly efficient methods for solving the problems of ensuring aircraft operations safety. One of the leading activities of the organization was the work on monitoring the functional state of a pilot in flight mode, as the weakest link in the ergatic biotechnological system “pilot-aircraft-environment”. Aviation medicine is a branch of medicine that studies the influence of environmental conditions and factors of professional activity on the health and performance of pilots in order to increase their efficiency, reduce morbidity, ensure flight safety and prolong flight longevity.

Development of means to control the physiological parameters of a pilot during a flight with the help of which the physiological characteristics of a pilot are recorded, and then their a posteriori processing to determine the impact of flight loads and airplane mechanisms on a pilot's body is a very urgent task within the framework of the ICAO concept.

A modern flight safety management system (SMS) should include technical and informational tools that make possible to control and predict the hazardous conditions of the above-mentioned system. That is why, a very important component of an SMS is to provide it with technologies for monitoring the physiological state of an aircraft pilot. An SMS should include complexes focused on significantly reducing the influence of the human factor in aviation accidents by at least 80% over the next 5 to 6 years. The concept of organizing the monitoring of the physiological state of a pilot based on spectrophotometry methods has a minimum number of correlators, high information content and the ability to quickly process the results obtained in real time on board. The main idea of developing a digital biometric complex for assessing the functional state of a pilot, in addition to timely notification of the deteriorating pilot`s health, is to maintain a personal flight history accumulated for each pilot of an aircraft throughout their professional careers. It is planned that the decision to admit the pilot to the flight will depend on the results of the analysis of his personal profile.

The article describes the effect on the state of the pilot's body overloads and workload on the aircraft management. The purpose of the article is to develop a structural-functional model of a digital biometric complex for assessing the functional status of an aircraft pilot, a feature of which is the synchronization of captured physiological parameters with pressure and acceleration values (overloads) acting on the pilot during a flight. Structural and functional diagrams are given and the principles of operation of the pulsoximetric module, which removes the primary physiological information, the processing unit for the physiological parameters of a pilot and the data acquisition unit, are described.
