cabin pressure
Cockpit gauge reading
Cabin pressure is the air pressure maintained inside an aircraft or spacecraft during flight.
At high altitudes, outside air is too thin to breathe, so pressurized cabins simulate conditions closer to sea level.
The flight attendant explained what to do if cabin pressure drops.
Loss of cabin pressure triggers oxygen masks and requires rapid descent.
