At what altitude is the cabin altitude warning system activated?

The cabin altitude warning system in the King Air 350 is designed to alert the crew when the cabin pressure altitude reaches 10,000 feet. This is crucial for maintaining passenger comfort and safety, as at this altitude, supplemental oxygen may be required for prolonged exposure. The system automatically activates an alert to ensure that the crew is aware of the cabin altitude and can take necessary actions if needed.

This warning plays an essential role in the operational safety of the aircraft, providing an early indication that the cabin pressure may not be maintained, which could lead to hypoxia or other altitude-related issues for passengers and crew. Understanding this limitation is critical for pilots and crew members, as it guides them in making informed decisions regarding altitude management during flight operations.
