Abstract
In some examples, a cabin pressure control and monitoring system includes an outflow valve, a first motor configured to operate the outflow valve to release fluid from a cabin, and a second motor configured to operate the outflow valve to release fluid from the cabin. The cabin pressure control and monitoring system also includes a first microcontroller configured to automatically control the first motor based on a pressure of the fluid in the cabin. The cabin pressure control and monitoring system further includes a second microcontroller configured to control the second motor based on user input and monitor the pressure of the fluid in the cabin. In some examples, a type of the first microcontroller is different than a type of the second microcontroller.
