Approved Personal Oxygen Concentrators (POCs) may be used during which phases of flight?

Approved Personal Oxygen Concentrators (POCs) are designed to provide supplementary oxygen to individuals who need it while traveling on commercial flights. The critical factor in their use is that they must be operational and effective during all phases of flight—boarding, taxi, takeoff, cruising altitude, descent, and landing. This comprehensive approval ensures passengers utilizing POCs have access to the necessary oxygen supply at all times, especially when cabin pressures might not provide sufficient oxygen levels for individuals with respiratory issues.

Permitting their use during every phase of flight emphasizes safety and comfort, as well as adherence to medical requirements. It recognizes that oxygen levels can vary significantly, especially during changes in altitude and pressure, making it essential for those needing extra oxygen to have uninterrupted access throughout the journey.
