Key Takeaways:

Supplemental oxygen is critical for flight safety at higher altitudes, with comprehensive FAA regulations (14 CFR Parts 91, 135, 121) dictating mandatory usage for flight crews and passengers based on altitude, flight duration, and aircraft pressurization status.
Oxygen systems are designed for different primary purposes depending on the aircraft type—emergency use for pressurized cabins and supplemental oxygen for unpressurized aircraft—and comprise various storage methods, delivery systems (continuous flow, diluter demand, pressure demand), and masks/cannulas.
Ensuring the safe and effective operation of oxygen equipment requires selecting products from trusted manufacturers, adhering to certification standards, and performing diligent pre-flight checks (like the "PRICE" method) and regular maintenance.

To conduct flights at higher altitudes, an aircraft must either have a pressurized cabin to replicate the pressure at a lower altitude, or its occupants must be given supplemental oxygen. Regardless of the system, basic knowledge of oxygen equipment can be critical whether you are flying a pressurized commercial jet or an unpressurized general aviation aircraft.

In unpressurized aircraft, the oxygen system is primarily intended to provide supplemental oxygen when required by altitude and time of exposure. It can also be used, when required, for protection in the event of smoke, fire, and/or fumes.
