Abstract:
1. A system for emergency ventilation of an aircraft cabin, comprising an air outlet valve for use in an aircraft which is adapted during normal operation of the aircraft as a component of a cabin pressure control system for adjusting a desired pressure level in the aircraft cabin to remove air from an interior of the aircraft into an environment around the aircraft, and which is further adapted during emergency ventilation operation of the aircraft as a component of a system for emergency ventilation of the aircraft cabin to introduce air from the environment around the aircraft into the interior of the aircraft, comprising: a control unit, which during emergency ventilation operation is adapted to receive signals indicating a defect in an aircraft air-conditioning system that impairs proper ventilation of the aircraft cabin, and which is adapted to control at least one valve flap of the air outlet valve during emergency ventilation operation of the aircraft into its open state so that air from the environment around the aircraft is directed into the interior of the aircraft through the open valve flap.
