How many minutes do the oxygen generators provide oxygen?

Explanation:
When you deploy an oxygen system, the supply is designed to last for a fixed amount of time, enough for the crew to manage the descent to a safe cabin altitude while keeping everyone on oxygen. On the CRJ-550, the oxygen generators feed the masks for thirteen minutes. That duration is chosen because it covers the typical descent time from cruise altitude to a breathable cabin level, allowing procedures to be completed and oxygen to remain available throughout the emergency. Shorter durations wouldn’t reliably carry you through the descent, while a longer duration isn’t needed given the aircraft’s descent profile and system design.
