31、ure to which the body is exposed minus 6.27 kPa 47 mmHg; this is the tracheal pressuredisplaced by water vapor pressure when the breathed air becomes saturated with water vapor at 37C.3.2.3 catastrophic failure condition, na catastrophic failure condition is one that would result in multiple fatalit
32、ies of theoccupants, or incapacitation or fatal injury to a flight crew member, normally with the loss of the aircraft.3.2.4 chemical oxygen generator, na chemical oxygen generator is defined as a device which produces oxygen by chemicalreaction; for more detailed information, refer to SAE AIR 825/4
33、.3.2.5 complex system, nA complex system is a system whose operation, failure modes, or failure effects are difficult tocomprehend without the aid of analytical methods or structured assessment methods, such as Failure Modes and Effects Analysis(FMEA) or Fault Tree Analysis (FTA). Increased system c
