Abstract
A method for emergency ventilation of an aircraft cabin is provided. The method includes controlling a first valve to supply air from the aircraft environment into a first aircraft fuselage area through the opened first valve and into the aircraft cabin. The method further includes controlling a second valve to conduct air from the aircraft cabin into a second aircraft fuselage area and out to the aircraft environment through the opened second valve. In their normal operation, the first and second valves serve as air outlet valves of an aircraft cabin pressure control system. The method further includes controlling a recirculation fan of an air-conditioning system to draw air supplied through the first valve into a mixing chamber of the air-conditioning system and to direct air from the mixing chamber into the aircraft cabin.
