Abstract

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