The bottle containing oxygen under pressure used in emergency situations is called what?

Explanation:
Oxygen under pressure used in emergencies on an aircraft is called a Portable Oxygen Bottle. This is a compact, high‑pressure cylinder that delivers supplemental oxygen when the main cabin oxygen source isn’t available or during medical or other emergency situations. It’s designed to be carried and used by crew or, in some cases, by passengers. The other terms don’t fit because they refer to something unrelated: a safety investigation agency (NTSB), a storage location for baggage (overhead bin), or a term with no connection to oxygen equipment (pairing).
