ABSTRACT:
One embodiment relates to a modular cabin pressure regulator that can receive its destination parameter and control settings from an avionics system or a manual selector and display. The modular pressure regulator includes a removable selector, a controller, and a monitoring unit to control an electro-mechanical actuator driven valve. Such modular design allows a single unit to be used for the cabin pressure selector and display, controller, and monitoring functions. In one embodiment, the selector module can be bypassed or removed and the same pressure regulator design can provide the controller and monitoring functions to send and receive inputs from an avionics system. This embodiment can be mounted directly on the electro-mechanical actuator driven valve or elsewhere on the aircraft.
