The atmospheric pressure decreases as the altitude rises. That is why the pressure level and change rate in the cabin need to be controlled in order to provide satisfactory pressure values for comfort and safety of passengers and crew. During all flight phases this is done fully automatically by the pressurization control system.
The complete cabin pressure control system provided by Liebherr includes outflow and safety valves, control panel, controller and software.
Liebherr supplies all kind of aircraft that need such function, like commercial airplanes, regional aircraft, military transport aircraft, business jets and fighters.
