At the altitude level of airplanes, the ambient temperature reaches below -45oC, and the outsideSince the drop in ambient pressure below approximately 5 psi [1] is below the levels that a human can withstand, the aircraft cabin is pressurized and air-conditioned by the system. During pressurization and air conditioning, arrangements are made within the limits that will ensure the suitability of human life. In these arrangements, a pressure difference within the limits that the cabin structure can withstand is taken into consideration when pressurizing. Because the pressure inside the cabin at high altitudes will be higher than the ambient pressure outside, a pressure force will occur, and the resistance of the aircraft structures to external pressure is less than the resistance to internal pressure. Other considerations are generally temperature, pressure, CO2, O3, humidity, and respirable volatile particles. In the system cycle applied by considering these criteria, it is aimed at ensuring a healthy and trouble-free flight by providing a suitable environment for passengers and flight crew.eninfo:eu-repo/semantics/closedAccess[Keywords Not Available]Book Chapter571588
