From what I understand the real reason this or equivalent layouts haven't happened is emergency exit times. I think the current requirement is that everybody can at least theoretically get off the plane in 90 seconds, and tightly-packed bunks inflate that time compared to seats.
- ufmace 6y agoI have to figure that those times are pretty contrived. Maybe you can evacuate in 90 seconds, if all of the "passengers" are skinny and athletic, and know what's going to happen, and don't have any extra stuff to try and grab, and there's no fire or smoke, etc. All that makes it a little hard to say what the real effect is. It would probably be a bit slower, but I bet with all of the optimizations for their 90 second test evacuations, the all-bed-plane could still evacuate faster than a plane-full of real passengers. I guess there's just nobody ambitions enough around to try something really new.
- throwaheyy 6y agoI have the same impression from videos like [1] but I suppose that is all that is needed to certify the aircraft. It may not happen in the "real world", you never know how everyone in a plane of hundreds passengers will react, but the design of the plane has to allow it to be "possible".
