Abstract
An aircraft cabin pressure control system that controls cabin altitude during aircraft ascent to a cruise altitude, such that, under most operational circumstances, the cabin altitude rate of change during the ascent is set to fixed value. The system uses a signal representative of the aircraft's expected cruise altitude. If, however, this signal is not available, the cabin pressure control system controls cabin altitude according to a schedule, and the cabin altitude rate of change may not be fixed during the aircraft's ascent.
