No placard in my company's B777 rest facilities saying which direction one must lie down, or where the O2 mask is. Wonder if that's specific to my airline. Will have to try the head toward the nose position ; wonder if it makes a difference in the quality of rest.
Are all B777 flight crew rest compartments the same, or are there different configurations ?
Well, at least I am lying down in a longitudinal direction. When we had A340s, the crew bunk was transversely situated. I personally found it more difficult to stay asleep in turbulence in that configuration.
