Irrelevant. The cabin pressure is controlled independently of the Earth's environmental altitude pressure.
> Probably the lower oxygen content.
That's literally exactly the same thing as the thing that I said.
- inferiorhuman 4y agoThe cabin won't be noticeably pressurized at 2,200 ft. While a 777 will pressurize the cabin slightly before takeoff the max cabin altitude is 8,000 ft. So, yes, there is a bigger change in pressure during an approach (from 8,000 ft cabin altitude to roughly the altitude of the field) than there is going into a steep dive from 2,200 ft.
