Dysag;
Probably not relevant to AF447, but the normal cockpit crew rest offering on the A340-500/600 is in the bulk hold. I believe there are several in service with it.
Thanks; that coincides with the arrangement we saw when asked to examine alternatives for the -500. Perhaps this is the normal offering from Airbus, from which changes may be made. We thought that for cockpit crew, being at the tail of the aircraft wasn't the best idea. That said, the other option behind the cockpit is prone to noise from the galley. I think the 777 has the best arrangement I've seen. The worst was the A330 which was in the J-cabin with a velcroed tent.
