Abstract
The present invention provides a cabin pressure control system that comprises a first outflow valve having a first motor controlled by a first outflow valve controller, the first outflow valve having a first backup motor controlled by a first backup controller. A second outflow valve has a second motor controlled by a second outflow valve controller, the second outflow valve also having a second backup motor controlled by a second backup controller. Upon failure of the first outflow valve controller, the second outflow valve controller controls the first outflow valve via the first backup controller and the first backup motor; and upon failure of the second outflow valve controller, the first outflow valve controller controls the second outflow valve via the second backup controller and the second backup motor.
