Еnsuring the safety of passengers during the depressurization of the aircraft cabin in high-altitude flights

The work includes an improved complex of technical means of collective informing about the values of the maximum reserve time of consciousness preservation in emergency situations (ES) of high-altitude flights. Statistical data on the occurrence of emergency situations (ES) on passenger aircraft were studied, which indicate the need to develop means of ensuring the safety of passengers of civil aviation aircraft in the event of emergency situations.One such complex is a complex of technical means of collectively informing passengers about the values of the maximum reserve time of maintaining consciousness in emergency situations in high-altitude flights. The object of the study is the organization of the safety of aircraft passengers in the event of an emergency.The article addressed the problem of ensuring the safety of aircraft passengers by identifying and eliminating some discrepancies between the possibilities of informing passengers and the lack of a set of technical means that allow such information to be implemented.To eliminate such discrepancies, a mathematical approach to the synthesis of integral indicators of the danger of high-altitude flight emergencies was considered, which made it possible to substantiate the need for the development of technologies for monitoring the situation in the aircraft cabin for the timely recognition of potentially dangerous situations caused by a decrease in barometric pressure. The work solves the scientific task of the research, which includes the development of a set of scientifically based technical solutions for informing aircraft passengers in the event of a high-altitude flight emergency.The peculiarities and distinguishing features of the obtained results, thanks to which they allowed to solve the researched problem, was the development of the algorithm of riskometry of the safety of high-altitude flights based on the human factor, with the subsequent implementation in the complex of technical means of ensuring safety. In order to build a complex of technical means of notifying passengers in the emergency of high-altitude flights, passenger safety assessments are given, calculated in real time on the basis of primary indicators available for registration during the entire flight (including in the event of an emergency). The practical application of the obtained results can be used in the aviation field in the event of an emergency.
