Technology of Informing Passengers of Civil Aviation in an Emergency of High-Altitude Flight

Abstract

An innovative technology of informing passengers of civil aviation aircraft about the potential danger of an emergency in high-altitude flight is presented, based on the calculation in real time of estimates of the reserve time of preservation of consciousness by a person when the aircraft cabin is depressurized. The methodology for calculating the assessment of the reserve time for maintaining consciousness in an emergency of high-altitude flight provides for the calculation of adequate estimates of the reserve time for any values of speeds and profiles of changes in barometric pressure in the aircraft cabin and the time of exposure to a hypoxic environment. The implementation of personalized information about the danger of an emergency in high-altitude flight is made in two versions: a system with the integration of an aviation oxygen mask and a system with the integration of an aviation passenger seat. For the first time, the results of the study make it possible to implement an innovative personified approach to personified risk metrics and personified information about the potential danger of an emergency in high-altitude flight in real time. The developed approach and the systems implementing it will find application on aircraft, during the operation of which there is a risk of depressurization of the cabin and / or cabin; when conducting tests in pressure chambers with the participation of volunteers, when staying in high altitude conditions and when solving other practical problems related to ensuring the safety of human activity in conditions associated with exposure to hypoxia. The stated information-technological concept of integrating the computing resources of an aircraft into the physical processes of personalized information about the potential hazard of an emergency in high-altitude flight has wide practical applications in the field of ensuring the safe operation of complex systems in extreme conditions.
