Since the third scenario deals with a B777, please use this type as an example. I would appreciate if your answers included these 3 scenarios. Assuming the latter, is there any way the perpetrator in the cockpit could prevent the cockpit depressurization ? One working hypothesis in the MH370 mystery is accidental or deliberate cabin depressurization. If there is smoke in the cabin, the pilot would need to prevent the smoke from entering the cockpit.ĭoes cabin depressurization (due to a hull breach for example) directly lead to cockpit depressurization? Or can the pilot prevent this by stopping the air outflow from the cockpit to the cabin?
hermetically sealing off the cockpit from the cabin ?ģ scenarios for which this question is interesting: Question: Can the pilot completely stop the airflow between cockpit and cabin, i.e. The airflow equalizes the atmospheric pressure in the cockpit and cabin. If my understanding of physics is correct, this means that there must be airflow between the cockpit and the cabin (otherwise a pressure difference would occur). This normally includes the cabin, cockpit, and lower-deck cargo holds. The entire vessel is pressurized equally from the forward pressure bulkhead to the aft pressure bulkhead. During normal operation the entire fuselage is pressurized equally:Īn aircraft fuselage does not contain separate compartments with different pressure values in each.
