Why does cabin pressure change during a flight, and not stay the same?
To keep the air inside the cabin at sea level pressure would require planes to be much stronger (and heavier). Letting some of the air out reduces the strength needed to prevent leaks, and it's still enough air to keep the people alive inside.
The Short Answer
To keep the air inside the cabin at sea level pressure would require planes to be much stronger (and heavier). Letting some of the air out reduces the strength needed to prevent leaks, and it's still enough air to keep the people alive inside.
