I must say that some of us engineers really should stop knocking the drivers. Has anybody ever driven a car for 12 hours or so & not felt knackered, no I thought not. At Virgin all the 747 400's have 2 crew rests, 1 at the rear of the a/c above the cabin/toilets & 1 at the pointy end next to the flight deck which is essentially just 2 bunks. The one at the rear has a pretty low ceiling & is also bunks only but I've kipped in there with no worries. The A340's also have 2 crew rests with a similar 2 bunk setup at the pointy end & a lower deck crew rest in the rear freight hold with access via a stairway from the cabin. The LDCR however is VERY cramped as there are 7 bunks slotted in there!! If you want some info on crew rests I suggest you contact C.F.Taylor's as they made the airbus crewrests. I hope I've been of some help to you & remember guys if it were'nt for the pilots flying & breaking the kites from time to time we'd be out of a job!!
