Key Takeaways:

  • Aircraft oxygen systems, both portable and built-in, are often severely neglected despite their critical role in ensuring pilot and passenger safety at altitude.
  • Pilots must adhere to FAA regulations regarding oxygen use based on altitude and should utilize pulse oximeters to accurately monitor blood oxygen levels for optimal safety.
  • All components of an oxygen system, from bottles and regulators to tubing and masks, require diligent and periodic maintenance, including hydrostatic testing and regular overhauls or replacements.
  • Extreme caution is vital when handling oxygen systems to prevent the explosive hazard that arises from mixing oxygen with oil or grease.
