ABSTRACT:
An aircraft cabin pressure control system implements control logic that significantly reduces potentially uncomfortable pressure bumps that can occur during aircraft take-off rotation both with and without cabin pressuring fluid flowing into the aircraft cabin. The control logic implemented by the cabin pressure control system, among other things, determines whether the cabin pressurizing fluid is flowing into the aircraft cabin. If the cabin pressurizing fluid is flowing into the aircraft cabin, aircraft cabin altitude is controlled to at least a first predetermined minimum altitude value below the take-off altitude. If the cabin pressurizing fluid is not flowing into the aircraft cabin, aircraft cabin altitude is controlled to at least a second predetermined minimum altitude value above the take-off altitude.
