Abstract
Disclosed herein is a hybrid mechanical/reactive pressure prevention system that includes a passive pressure control device operably coupled to a door that allows air within a pressurized vehicle to flow out of the pressurized vehicle. An event module detects a door event in the pressurized vehicle. The door event indicates that a door is not secure and air within the pressurized vehicle is being released through the passive pressure control device. An altitude module determines an altitude of the pressurized vehicle in response to detecting the door event. An electronic pressure control device one or more of reduces air inflow into the pressurized vehicle and increases air outflow out of an active pressure control device of the pressurized vehicle in response to the altitude of the pressurized vehicle being below a cutoff altitude.
