How is cabin pressurization controlled in the ERJ series?

Cabin pressurization in the Embraer Regional Jet (ERJ) series is effectively controlled by the cabin pressure control system and outflow valves. This system regulates the cabin pressure by modulating the outflow of air from the cabin, ensuring it remains at a comfortable level for passengers and crew during various phases of flight.

The cabin pressure control system automatically adjusts to changes in altitude and can regulate the pressure to maintain safety standards. Outflow valves, which are integral to this system, allow excess cabin air to escape, thus helping to maintain a safe and comfortable pressure differential between the inside of the cabin and the outside atmosphere as the aircraft climbs or descends.

This method of control ensures that the aircraft complies with regulatory requirements and provides a safe environment, without requiring constant manual input from the pilots. Therefore, using an automated system that responds to flight conditions enhances operational safety and reduces the workload on the flight crew.
