Abstract: To ensure the reliable functioning of the indicators of the reserve time of consciousness preservation by a person in
conditions of hypoxia, a special device for their verification and calibration has been developed. The device includes a pressure
regulator, a tableau for indicating the reference pressure, a tableau for indicating the standby time of consciousness, a hose with a
connector for connecting to the barometric pressure sensor, a compressor, a pressure regulator and a microprocessor. The developed
device provides the ability to monitor the performance of the means of collective and individual informing the crew of aircraft
passengers about the value of the maximum reserve time for maintaining consciousness in emergency situations of high-altitude
flights.
Index terms: indicator of the reserve time of consciousness preservation, verification of the indicator of the reserve time of consciousness preservation, calibration of the indicator of the reserve time of consciousness preservation, safety of high-altitude flights, oxygen equipment.
