When the flight plan indicates a landing airport above 8,000 ft, what adjustment does the pressurization system make?

The pressurization system in an aircraft like the Dassault Falcon 7X is designed to adjust cabin pressure according to the altitude of the landing airport. When the flight plan indicates a landing airport above 8,000 feet, the system will switch to high altitude mode. This mode ensures that the cabin is pressurized appropriately to avoid discomfort for the passengers and crew, as well as to maintain safety standards during descent and landing phases.

In high altitude mode, the system will actively manage the cabin altitude to ensure that it stays within the limits of human tolerance, reducing the risk of hypoxia or other altitude-related issues. This adjustment is crucial as it prepares the aircraft for landing at higher elevations, where atmospheric pressure is significantly lower than at sea level.

Adjusting to high altitude mode effectively allows the pressurization system to provide a stable environment for occupants from the approach through to landing, considering the higher altitude of the destination airport.
