ABSTRACT:
A cabin pressure control system for aircraft includes a controller for receiving and comparing set point and actual values for an aircraft cabin pressure. A speed-controlled drive for an air outlet valve is connected to the controller for triggering the valve as a function of the comparison. A remote indication is issued to the controller solely regarding a newly established actual cabin pressure, without a remote position indication from the valve.
