Upper Deck Galley Elevator On 747-8

Where is the galley elevator/cart lift located on the 747-8s ? I would imagine since the -8 has a longer upper deck, the elevator had to be relocated in order for it to match up with one of the main deck galleys. Since the -8s upper deck carries more pax, did Boeing enlarge the cart lift?

I always thought the lift was located on the back wall of the upper-deck galley, but I seem to be wrong.

Thanks!

The entire fuselage plug was extended, so in theory the upper and lower deck galley should still be in the same place relative to each other. But I still don't see an elevator there..?

If it is the same as the -400, the lift should be directly to the left of the photographer.

It is the same size. The galley is a bit larger and the closet that was behind the staircase is now gone.
If you have never designed an airplane part before, let the real designers do the work!

What they said. On the 400, the lift is about four feet to the left of the staircase (looking aft, #2 side), and in line with the top step horizontally. From what I've seen, on the 8i, the entire CISD station is more or less the same, of course with some updates, just further aft. Looking at that photo, it should be well within reach of the photographer's left hand.

On the following video of the 747-8I upper deck galley, the cart lift is visible at elapsed time 0,13 minutes (with the crew-bag in front) :

For better understanding here is the cabin lay out of the Lufthansa 747-830. The cart lift is located just aft of the aft upper deck toilet.

The location of the lift is exactly the same as on the 747-400 series, because the fuselage of the 747-8I has been extended (by a fuselage plug) just aft of the upper deck escape doors.

I expect it's still an option. LH appears to be going for a premium-heavy config at the moment, so they don't seem to be worried about floor-space and the crown galley must add weight.

A carrier with a heavier bias towards Economy seating might want to kick the Economy galleys up into the crown.

I'd actually see more reason to do it with the premium heavy configuration since business class requires so many more carts than economy does. The 748 business class galley is huge and larger than the economy galley. Floor space is always important regardless of premium heavy or economy heavy configuration.

I believe the upper deck galley has 15 full and 2 half carts for only 32 seats!

True, but usually premium cabin service is done by trays from the galley as opposed to directly off carts at the seat like in Economy.

So for premium cabin, I expect it's much easier to do it on the main deck where with Economy, you can do all the prep in the crown galley, load the distribution carts and then take them down to the main deck.


For those aircraft that had hold galleys, were these used for both premium and Economy cabins? And if used for premium, was service from the cart or did they prep it downstairs, bring it up to tray and then serve?

It must be possible to install a crown galley in the place reserved for the skyloft installation in the 747-8I/BBJ aircraft.

However AFAIK the 747-8I/BBJ aircraft are built according a different standard design then the airline 747-8I aircraft.

The 747-8I Airline configuration is built according Basic number block R8001 and further.
The 747-8I BBJ configuration is built according Basic number block R8401 and further.

Examples :
L/N 1434 - 747-8JK - R8401 - RC001 is the first built BBJ aircraft
L/N 1435 - 747-830 - R8001 - RC021 is the first built airline (DLH) 747-8I

IMO modification afterwards to allow for crown galley installation will be very expensive, The crown galley possibility must be factory installed (re-routed steering cables, air conditioning ducts, wire bundles and attachment points for a galley floor.) to allow for an economic crown galley installation.

I would expect there is little to any difference in the crown area between the VIP and passenger versions, otherwise that just needlessly drives up cost and complexity.

The OSU's are installed aftermarket for the VIP birds, but that may just be due to the genera outfitting being done post-delivery.

I would expect the galleys to be installed on the line for a passenger plane due to simplicity, but I would expect they could be added afterwards (perhaps with an STC?).

The KLM 744 door 3 overhead crew rest were installed retrofit and certified via STC.

Not really detailed, but this should at least give you an idea of the general positioning.

I'd thought that a bigger issue is that the "skyloft" area removes the center bin space where it would be most needed (right?)-- above the economy seating. If, because business class is lower density, you could forgo that bin space, you might be able to add the galley above it, but then biz class could not be under the extended upper deck-- it would need to be farther back.

I'm assuming that the crew rests fitted above economy are much shorter in height than the "skyloft" and don't sacrifice bin space. I could also see some creative cart storage up there that doesn't sacrifice center bins w/o an actual habitable galley, but a true skyloft galley needs to be aft of the overwing door, and it would remove bins.

I believe this is only the case with the OSUs fitted to 747-8 VIP frames as they have no need for luggage bins. Closeout fairings are instead fitted in the location the bins would normally be.
