Abstract
A cabin pressure control system for an aircraft in which the controller provides control signals to an outflow valve by way of a pneumatic amplifier relay means, has the memory or rate chamber of the controller providing the pneumatic signal to the relay instead of the usual case where the signal comes from the reference pressure chamber. Any one of several forms of relays may be used in this novel system. One form of relay includes a feedback signal from the outflow valve.
