Aircraft cabin pressure is commonly pressurized to a cabin altitude of 8000 feet or less. That means that the pressure is , which is the ambient pressure at . Note that a lower cabin altitude is a higher pressure. The cabin pressure is controlled by a cabin pressure schedule, which associates each aircraft altitude with a cabin altitude. The new airliners such as the Airbus A350 and Boeing 787 will have lower maximum cabin altitudes which help in passenger fatigue reduction during flights.
