Key Takeaways:

Supplemental oxygen is critical for safe high-altitude flight and emergency situations (like depressurization or smoke), with FAA regulations (Parts 91, 135, 121) defining specific usage requirements for crew and passengers based on altitude, flight duration, and aircraft type.
Aircraft oxygen systems include various storage methods, three main delivery types (continuous flow, diluter demand, pressure demand for increasing altitudes), and compatible masks or cannulas, which must be selected according to operational needs.
Pilots are responsible for understanding their oxygen equipment's limitations, performing pre-flight "PRICE" checks (Pressure, Regulate, Indicator, Connections, Emergency readiness), and ensuring regular maintenance to guarantee system reliability and flight safety.

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.
