Research of interaction of flight safety management system with aircraft on-board equipment

The paper presents statistical data on aviation accidents, according to which, 87% accidents are influenced by the human factor. Improving the flight safety of the aircraft should be based primarily on the introduction of decision support systems that can simulate the development of a dangerous situation. The advantages and disadvantages of intelligent decision support systems created in Russia and abroad are considered. Among the serious disadvantages there is a lack of forecasting changes in the values of variables that affect flight safety (psychophysical state of the crew, flight conditions in the aggregate of external and internal changes). A flight safety management system with a two-level approach to recognizing changes in aircraft operating conditions is proposed. The input data of the system is information on the status of the crew, a control object and flight conditions. The composition and description of the on-board equipment of the aircraft interacting with the safety management system of the flight has been given. The availability of information from this equipment allows you to identify and lift the threat of an accident. There have been considered the main types of failures of airborne equipment and of the aircraft flight safety management system. The analysis of the throughput capacity of the system communication line with the complex of on-board equipment has been performed, which allows to determine loading of digital communication lines on board the aircraft. Functioning the aircraft safety system under failures of interacting equipment has been studied. Particular attention is paid to determining the probability of failure of the functions of the aircraft flight safety management system under the influence of its internal and external failures.
