In a method for emergency ventilation of an aircraft cabin (12) a leak is detected in the area of an air mixer (24) of an aircraft air conditioning system (16). An emergency air flap (38), which in a closed position prevents an air exchange between an aircraft area (40) adjacent to the air mixer (24) and the aircraft cabin (12), is controlled into an open position. Finally, air from the aircraft area (40) adjacent to the air mixer (24) is conveyed through the open emergency air flap (38) into the aircraft cabin (12).

L'invention concerne un procédé de ventilation d'urgence d'une cabine d'avion (12) selon lequel une fuite est détectée dans la région d'un mélangeur d'air (24) d'un système de conditionnement d'air (16) d'avion. Un clapet de ventilation d'urgence (38) qui empêche, dans une position fermée, un échange d'air entre une zone d'avion (40) voisine du mélangeur d'air (24) et la cabine d'avion (12) est manuvré dans une position ouverte. Enfin, l'air provenant de la zone d'avion (40) voisine du mélangeur d'air (24) est transporté via le clapet de ventilation d'urgence (38) ouvert dans la cabine d'avion (12).
