The cabin pressurization was provided by bleeding air from the engines' turbo supercharger, the compressor outlet fed into the cabin and was controlled by the flight engineer. [4] This system was able to maintain a cabin altitude of 12,000 ft (3,658 m) while flying at 30,000 ft (9,144 m). [ 5 ]
A cabin humidity control system may be added to the ECS of some aircraft to keep relative humidity from extremely low levels, consistent with the need to prevent condensation. [8] Furthermore, the Boeing 787 and Airbus A350, by using more corrosion-resistant composites in their construction, can operate with a cabin relative humidity of 16% on ...
SyberJet SJ30 (2005) First civilian business jet to certify 12.0 psi pressurization system allowing for a sea level cabin at 41,000 ft (12,497 m). [ 44 ] The first airliner to enter commercial service with a pressurized cabin was the Boeing 307 Stratoliner , built in 1938, prior to World War II , though only ten were produced before the war ...
The decision by Alaska Airlines to stop flying one of its planes over the Pacific Ocean to Hawaii due to warnings from a cabin-pressurization system — yet keep flying it over land — is raising ...

An example of this is the 2005 Helios Airways Flight 522 crash, in which the maintenance service left the pressurization system in manual mode and the pilots did not check the pressurization system. As a result, they suffered a loss of consciousness (as well as most of the passengers and crew) due to hypoxia (lack of oxygen).
Initial design of the DFS 228 was undertaken before the outbreak of war as a research aircraft, the DFS 54, aimed at developing a high-altitude escape system for sailplanes. The project was suspended by the commencement of hostilities , but was revived in 1940 when the Reichsluftfahrtministerium (RLM - "Reich Aviation Ministry") delivered the ...
A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. [1] Other instruments that might be connected are air data computers, flight data recorders, altitude encoders, cabin pressurization controllers, and various airspeed switches. Errors in pitot–static system readings can be extremely ...
