3 unusual facts about cabin pressurization


Cabin pressurization

The control system for this was designed by Garrett AiResearch Manufacturing Company, drawing in part on licensing of patents held by Boeing for the Stratoliner.

Joseph Mangan

Joseph Mangan is an American aerospace engineer who, in 2004, told European aviation authorities of his belief that the microprocessors controlling cabin pressurization valves in the new Airbus A380 might allow a sudden depressurization of the passenger cabin in flight—which, at normal cruising altitudes, could endanger the lives of people aboard the aircraft.

The review process, incorporating the participation of Joseph Mangan, successfully finished in late 2006 when the Airbus A380 including the internal communication system and the microprocessors of the cabin pressure control system was certified by EASA and FAA.
