The pressure inside the cabin is technically referred to as the equivalent effective cabin altitude or more commonly as the cabin altitude. This is defined as the equivalent altitude above mean sea level having the same atmospheric pressure according to a standard atmospheric model such as the International Standard Atmosphere. Thus a cabin ...
That means that the pressure is 10.9 pounds per square inch (75 kPa), which is the ambient pressure at 8,000 feet (2,400 m). 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 pressure maintained within the cabin is referred to as the equivalent effective cabin altitude or more normally, the ‘cabin altitude’. Cabin altitude is not normally maintained at average mean sea level (MSL) pressure (1013.25 mbar, or 29.921 inches of mercury) throughout the flight, because doing so would cause the designed ...

As the air pressure outside becomes increasingly lower than that inside the cabin, the pressure difference causes the door to seal itself closed and prevent leakage. The region of the fuselage around the opening for the door must be reinforced and this adds weight, so for large doors an alternative to the plug design is commonly used.
It works by measuring pressures or pressure differences and using these values to assess the speed and altitude. [1] These pressures can be measured either from the static port (static pressure) or the pitot tube (pitot pressure). The static pressure is used in all measurements, while the pitot pressure is used only to determine airspeed.
Mean airway pressure typically refers to the mean pressure applied during positive-pressure mechanical ventilation. Mean airway pressure correlates with alveolar ventilation, arterial oxygenation, [1] hemodynamic performance, and barotrauma. [2] It can also match the alveolar pressure if there is no difference between inspiratory and expiratory ...
