The ditch switch

When an A320 wants to take a bath in a river, you have to prepare the plane for it, as there are many inlets for air. An article in a forum describes the procedure: There is really a “Ditching” switch you can use to close all inlets below flotation line at once. A source near to Airbus told me a few minutes ago, that all newer planes have such a switch. I´m still searching on my A380 cockpit poster … ;) PS: When you look at this photo of the overhead panel … the switch is in the third row from below the third one from the right side
