What Is Cabin Altitude?
The effective altitude inside a pressurised aircraft cabin, which is lower than the actual flight altitude but still above sea level.
A jet cruising at 41,000 ft typically maintains a cabin altitude of 6,000–8,000 ft. That difference matters clinically: reduced partial pressure of oxygen, expansion of trapped gas, and lower humidity.
For some patients — recent thoracic surgery, severe hypoxia, brain injury — sea-level cabin operation is required. This is achievable in some jets at the cost of range and altitude.
