An alternate ventilation system for an aircraft having a body structure and a plurality of electronic devices is provided. The ventilation system includes a ventilation conduit, an inboard supply valve, a first outflow valve and a second outflow valve. The ventilation conduit is adapted to be coupled to the body structure for directing a ventilation flow of air along a predetermined flow path. The inboard supply valve is coupled to the ventilation conduit and adapted for drawing air from the cabin into the ventilation conduit when positioned in the open condition. The first outflow valve is coupled to the ventilation conduit and adapted for discharging at least a portion of the ventilation flow from the ventilation conduit to a point outside the body structure when positioned in the open condition. The second outflow valve is coupled to the body structure and operable in a first mode and a second mode. The first mode is adapted to selectively enable a discharge airflow from the cabin and the second mode is adapted to selectively enable an input airflow into the cabin. A method for ventilating an aircraft is also provided herein.
