Key Takeaways:

Aircraft require oxygen systems for high-altitude flights, either via pressurized cabins or supplemental oxygen, serving both routine needs and emergencies like pressurization loss or smoke.
FAA regulations (14 CFR Parts 91, 135, and 121) establish specific mandates for supplemental oxygen use by flight crews and passengers, with requirements varying based on altitude, flight duration, and aircraft type/operation.
Oxygen systems consist of storage, delivery mechanisms (continuous flow, diluter demand, pressure demand), and appropriate masks or cannulas, each designed for specific altitude ranges.
Ensuring the safety and reliability of oxygen equipment is paramount, requiring careful selection, adherence to certification processes, and diligent pre-flight "PRICE" checks (Pressure, Regulate, Indicator, Connections, Emergency) 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.
