Boeing Considers Options For 747-8

Boeing has confirmed the exterior lines for its new 747-8 aircraft but is still weighing alternatives on a handful of more specific issues before the final configuration of the aircraft is decided in the third quarter, program head Jeff Peace said yesterday.

Boeing is now at the stage where it is "making tradeoffs at [the] detailed level," said Peace. These issues include cabin architecture and whether advanced alloys should be used on some individual components. Engineers have still not decided whether it is worth extending fly-by-wire technology to the outboard ailerons.

Regarding the aircraft interior, questions such as which side the stairs should be on and the location of galleys are still under discussion. Boeing is proposing taking the galleys from the Door Four area and moving them upstairs, which would create space for 12 more seats on the main deck. The airframer also is still undecided on whether to include the self-dimming windows that are being developed for the 787...

...The airframer believes it won't have to conduct static test to failure on the wing. Because fundamental structural locations are unchanged from the -400, the structural analysis from the -400 will still be valid, Peace said. Boeing is still deciding whether it will modify existing wing production tools or build new ones...

Good article about the status of 748 design, interesting that Boeing may not have to "break" a wing.

There must be, no way to fit 450 seats in the 3-class configuartion on the main deck.

My guess is he's considering moving the "door four galley area" to the "loft" area of the fuselage behind the "hump" to accommodate the extra seats on the main deck.

Page 8.

Also a video of use of "unused crown space" which points out galley storage as well. I doubt you'll see any of the other ideas used.

What an absolutely awesome video! Thanks very much for sharing that one!

How much space is actually up there? Could they have a galley in one location, and also have suites?

Surprisingly enough, I imagine there would be a lot of takers for Economy Suites, especially on 14 hour sectors and things like that.

I thought the idea of the exercise bikes was novel! The whole concept is just screaming to be utilised. It doesn't appear to be over the top or silly (barring that water feature in the entry, can't see that happening unless it's very light) and could actually have applications in the real world. Nice work!

Little market for suites on 747-8

...so far, airlines are showing little interest in such things as 747-8 sky suites...

It appears unlikely, given the reaction from the recent visit to the mock-up by those airline interior specialists, that these sky suites and other amenities will show up on many, if any 747-8 passenger planes.

But the visitors did like one feature that seems certain to be on the 747-8. The added room above the main cabin allows for a galley, which will free up seats in the main cabin for more paying passengers.

The sky suites add weight and shorten the range.

Sure, but it can't be a hell of a lot of weight really, can it?

Are there figures for that somewhere?

i doubt any of the sky loft ideas in the video will ever be used. but if they are, would a passenger also have to buy a seat in the cabin for T/O and landing? i wouldnt think you would be able to stay in the sky loft for T/O and Landing...too bad there arent any windows up there

I'd be very surprised if the galley option was not used. But anything that has to do with passenger usage, I agree, I don't give it much of a chance at all either.

But all these things add weight to the plane, which cuts into performance.

Even a little extra weight is significant which is why some arilines even eliminate the outside paint job from some cargo airliners.

Quoting HighFlyer9790 (Reply 12):

Yes, because there are no exits on the upper level, it likely would be an economy seat to use for takeoff and landing.

I would imagine they will decide on this as the only use beyond crew rest for the loft.

Similar to the below deck galleys on many planes, the above deck galley would be used for food prep and heating, as well as cart storage, allowing for much smaller main deck galleys for Y and J cabins, basically like a "butler's pantry" for those who know what that is.

I would imagine the F galleys would remain fully functional, and due to logistics, the "upstairs" galley for the upper deck seating would also remain fully functional.

But even by doing this, you'd get a lot more seats into the 748 vs. the 744, considering the large galleys that some airlines have to have for their long-range flights (like QF, for example). With the extended range and extra seating, the 748 becomes a VERY strong candidate for QF, UA, BA, NZ, VS, SQ, etc. for their longest range 747 routes especially. Not that they'd all buy them, but I'd expect at least two of those carriers to buy the 748.

Nice all those features! But, simple thoughts pop-up.

If all these suites are indeed installed, what will that do for the turn-around time> Cleaning will take forever, making up beds etc.

Next, how to keep the atmosphere crips in those suites?

If just galley and crew rest upstairs, the stairway is "employee only". If also bunks, the stair for general pax would need to be larger and also "inviting". I would think that this attic galley could also allow the First galley be a bit smaller as about half the carts coould go upstairs, except the carts would need to be rolled thru cattle class.

However, the First attendands could roll the cart back on their way to their rest stage.

There is a huge amount of food and drinks needed for 450 people over 16 hours. That is like 1,700 meals and snacks and like 2,100 beverages.

I have made this point before, yes you add weight in the attic with the suites, but you remove weight by not needing high end FC seats on the main deck, all they need average seats in combo with the suites. It is a trade off, not simply the addition of more weight. High end seats are very very heavy.

A 747 is not a 737 with a 20 minute turn around time. Take QF at LAX and LHR, the aircraft arrive in the morning and mostly don't depart until the evening.

Imho, the galley option will happen, the rest will depend on what happens with the first A380 configs for SQ, QF and EK. If they end up with an entirely new passenger experience internationally for the premium pax, you will see these options used on the 748. If it is similar to now, you may not. It's all wait and see.

You stake out a position contrary to the article and I have to prove it for you? I don't have to provide you figures. Look them up yourself.

I just quoted from the article, which I trust over your uninformed musings.

Touché!

"But all these things add weight to the plane, which cuts into performance. And airlines would have to charge passengers a premium to use such amenities."

The article is inferring that making passengers pay a premium for these amenities is a big no no and shouldn't be done. Airlines like BA, SQ, QF and the like extort money at present from the premium classes for their bed products. I am certain they could do the same with these new concepts.

However, as I am prone to "uninformed musings", perhaps I should refrain from comment altogether  Wink

There are two issues here, the performance and the premium. I agree with you about the premium, but the added weight reducing range could be a real deal killer. What good is it to buy a bed if you are going to be awaken for a tech stop?

It is less certain if airlines will ever order a 747-8 with the Sky Suites. The added weight would cut into the plane's performance, although airlines could charge first- or business-class passengers more to use them.

I was replying to Keesje, not you. He sort of suggested that Boeing could have moved all seats out of the upper deck which my point was .. physical impossibility in terms of accomodating 450 pax. Not to mention of other aspects of sheer idiocy of such a configuration.

25 ClassicLover : Oh, I agree with you on that (even if I personally wouldn't care). However, I think this poster has a point - You could have standard normal J class
26 BoomBoom : I agree he has a point. There will be some offset of the added weight in the attic from not needing high end FC seats on the main deck. I doubt if it
