At what altitude must the baggage door be closed and latched?

The proper altitude for closing and latching the baggage door on the Dassault Falcon 7X is indeed 40,000 feet. This requirement is crucial for maintaining cabin pressure integrity and ensuring safety during flight. At the operational altitude of 40,000 feet, the aircraft's pressurization system must function correctly to prevent any risk posed by an improperly sealed baggage compartment.

Maintaining the baggage door in a closed and latched position at high altitudes is essential because the pressure differential between the inside of the aircraft and the external environment can cause stress on the door, potentially leading to failures if not secured.

While other altitudes may be listed, they do not align with the specific operational guidelines necessary to ensure the structural integrity of the aircraft during cruise. Following the correct altitude for closing and latching the baggage door ensures compliance with aviation safety regulations and the aircraft manufacturer's recommendations.
