Abstract
An aircraft cabin pressure control system tester includes a first tester component having a vacuum pressure-sensing gage which indicates the static atmosphere in inches of Hg and a second tester component having a differential pressure-sensing gage which indicates the pressure/vacuum in inches of H.sub.2 O. When the components of the tester are connected respectively in communication with lines connecting the controller of the system to static atmosphere ports and a pressure regulator valve, the tester can be used to determine which one, if any, of the pressure controller, air compressor and regulator valve of the pressure control system is faulty.
