Flying steadily at 37,000 ft, what can we say about the oxygen level in the cabin?
Understand the Problem
The question is asking about the relationship between the altitude of 37,000 feet and the oxygen levels inside an aircraft cabin. It is exploring what changes, if any, occur to the oxygen levels at that altitude compared to ground level.
Answer
It is lower than on the ground.
The cabin oxygen level is lower than on the ground.
Answer for screen readers
The cabin oxygen level is lower than on the ground.
More Information
In aircraft, the cabin air is pressurized to simulate an altitude of about 6,000 to 8,000 feet, which results in lower oxygen levels than at sea level.
Tips
Mistakenly assuming cabin oxygen levels are higher due to pressurization. Cabin pressure doesn't equate to sea level pressure.
