Abstract
Methods and apparatus are provided controlling aircraft cabin pressure, and more specifically engine bleed air manifold pressure, during aircraft descent. An aircraft engine bleed air manifold control pressure setpoint is to either a descent pressure setpoint or a cruise pressure setpoint by determining a rotational speed of an aircraft engine component, determining a component speed setpoint value, and determining aircraft vertical speed. The engine bleed air manifold control pressure setpoint is set to the descent pressure setpoint if either the determined rotational speed of the aircraft engine component is below the component speed setpoint value or the aircraft vertical speed is less than a predetermined vertical speed value.
