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.

1. A method for emergency ventilation of an aircraft cabin in an aircraft, comprising: detecting a leak in the area of an air mixer of an aircraft air conditioning system, through which air escapes from the air mixer into an aircraft area, the aircraft area being adjacent to the air mixer and within the aircraft,electronically controlling an emergency air flap, which in a closed position prevents an air exchange between the aircraft area adjacent the air mixer and the aircraft cabin, into an open position, which allows air escaping from the air mixer to flow out of the aircraft area adjacent the air mixer into the aircraft cabin, andconveying air from the aircraft area adjacent the air mixer through the open emergency air flap into the aircraft cabin. 2. The method according to claim 1, further comprising: controlling an air outlet valve of an aircraft cabin pressure control system into an open position in such a way as to generate in another area of the aircraft that is adjacent to the air outlet valve a pressure that is lower than the pressure in the aircraft area. 3. The method according to claim 1, further comprising: controlling an air conditioning unit of the aircraft air conditioning system in such a way that a maximum air-mass flow is generated by the air conditioning unit and supplied to the air mixer. 4. The method according to claim 1, further comprising: controlling an emergency ram-air inlet flap into an open position so that aircraft ambient air is supplyable through an emergency ram-air inlet to the air mixer. 5. The method according to claim 1, further comprising: controlling recirculation fans of the aircraft air conditioning system in such a way that their operation is interrupted. 6. The method according to claim 1, wherein the emergency air flap is disposed in a cabin trim panel or formed by a cabin trim panel. 7. A system for emergency ventilation of an aircraft cabin in an aircraft, comprising: an electronic control unit, which detects a leak in the area of an air mixer of an aircraft air conditioning system, through which air escapes from the air mixer into an aircraft area, the aircraft area being adjacent to the air mixer and within the aircraft, and which electronically controls an emergency air flap, which in a closed position prevents an air exchange between the aircraft area adjacent the air mixer and the aircraft cabin, into an open position, which allows air escaping from the air mixer to flow out of the aircraft area adjacent the air mixer into the aircraft cabin, anda device that causes air to be conveyed from the aircraft area adjacent the air mixer through the open emergency air flap into the aircraft cabin. 8. The system according to claim 7, wherein the device that causes air to be conveyed from the aircraft area into the aircraft cabin comprises an air outlet valve of an aircraft cabin pressure control system that is adapted to be controlled into an open position in such a way as to generate in another area of the aircraft adjacent to the air outlet valve a pressure that is lower than the pressure in the aircraft area. 9. The system according to claim 7, wherein the electronic control unit is further adapted to control an air conditioning unit of the aircraft air conditioning system in such a way that a maximum air-mass flow is generated by the air conditioning unit and supplied to the air mixer. 10. The system according to claim 7, wherein the electronic control unit is further adapted to control an emergency ram-air inlet flap into an open position so that aircraft ambient air is supplyable through an emergency ram-air inlet to the air mixer. 11. The system according to claim 7, wherein the electronic control unit is further adapted to control recirculation fans of the aircraft air conditioning system in such a way that their operation is interrupted. 12. The system according to claim 7, wherein the emergency air flap is disposed in a cabin trim panel or formed by a cabin trim panel.
