I want to ask if an overwing exit slide in an Airbus A320 can be opened at all when landing or ditching. Is the exit still usable? Or it is blocked and we have to move the passenger to another one?
And in ditching is the water level one of the reasons why it will not be opened and the reason the exit is blocked? If it was the case, why to consider the primary exit in ditching is the over wing exit? If it is deployed we will not use it in ditching.
