Any failure of cabin pressurization above 10,000 ft (3,048 m) requires an emergency descent to 8,000 ft (2,438 m) or the closest to that while maintaining the minimum sector altitude (MSA), and the deployment of an oxygen mask for each seat. The oxygen systems have sufficient oxygen for all on board and give the pilots adequate time to descend ...
The oxygen, cabin pressurization, landing gear control, aircraft health and trend monitoring systems are adapted from the G650. [43] The auxiliary power unit is a Honeywell HTG400G. [41] The cabin pressurization reaches 10.69 psi (0.737 bar). [44]
It was the second American aircraft to feature cabin pressurization. [1] It was initially described as a "supercharged cabins" by the Army. The XC-35 was a development of the Lockheed Model 10 Electra that was designed to meet a 1935 request by the United States Army Air Corps for an aircraft with a pressurized cabin. [2]
In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics , smoke detection , and fire suppression .
The 10.3-psi cabin pressurization maintains a 4,500-ft. cabin altitude up to FL 450 and 5,680 ft. at the FL 510 ceiling. [36] The cabin has an unobstructed length of 14.6 m (48 ft) while the floor is dropped by 51 mm (2.0 in) from the Challenger to increase width at shoulder level, while the windows have been repositioned and enlarged by 25%.

Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...
Cabin doors are designed to make it nearly impossible to lose pressurization through opening a cabin door in flight, either accidentally or intentionally. The plug door design ensures that when the pressure inside the cabin exceeds the pressure outside, the doors are forced shut and will not open until the pressure is equalized. Cabin doors ...
Cabin pressurization is the active pumping of compressed air into the cabin of an aircraft in order to ensure the safety and comfort of the occupants. It becomes necessary whenever the aircraft reaches a certain altitude, since the natural atmospheric pressure would be too low to supply sufficient oxygen to the passengers.
