What type of oxygen system is equipped on the Pilatus PC-12 NG?

The Pilatus PC-12 NG is equipped with a built-in oxygen system, which is specifically designed to provide supplemental oxygen to the crew and passengers at altitude. This system typically includes an onboard oxygen tank, oxygen masks, and necessary regulators, allowing for easy access and use during flight.

A portable oxygen system, while useful in other contexts, is not fitted on the PC-12 NG as the built-in system meets the operational requirements efficiently and ensures safety without the need for separate, removable equipment. Other options, such as a centrifugal or emergency oxygen system, do not accurately describe the configuration of the PC-12 NG's oxygen provision, as they cater to different aviation needs and standards that the aircraft does not employ.

Understanding this built-in system is crucial for ensuring that safety regulations are met during flight operations, especially when flying at higher altitudes where the need for supplemental oxygen arises.
