Why No Sky Interior On LH 747-8i?

Sat May 05, 2012 5:07 am

I'm just wondering why LH didn't take this option. Is it due to cost? Does anyone know how much extra the LED lighting costs? IMO it makes the cabin look much nicer and seems to be beneficial in terms of adjusting to new time zones on long-haul flights, which these a/c will be used on.

Did Boeing even develop the Sky Imterior for the 748i?? This looks pretty much identical to the interior of the 747ER, so maybe it was costs at Boeing's end?

AFAIK, they do have LED lighting.



The F-class section.

Just because it happens to be putting out a comfortable soft white glow doesn't mean it's not LED. Of all the different sorts of lights I own, LED's give the best, warmest, homiest white.

Yes. The overhead and sidewalls are 787 style. Sadly, the windows are not.

Yes, its very similar to the one in the 787, except for the windows (has conventinal shades). See http://www.airlinetrends.com/2011/02...oeing-dreamliner-interior-737-747/ for some pics

Did you see the pics in the link in the original post? Unless they had the LED's set on yellow, they look suspiciously like fluro tubes.

Can anyone shed any light on this? No pun intended.

Development of the 747-8 Interior design.

Initial (2005) design changes to the interior (from the 744) centered around the door 2 entryway, the lighting and the windows.

- The door 2 entry was re-architected with a new staircase and surround structure. The motive behind this change was a desire to communicate to the passenger as soon as they board the airplane that it is a new 747 and not a 744.

- The windows were changed to the 777 elliptical type . These windows give the cabin a more open feel, costs less to produce and weigh less. 787 windows were considered, but with an aluminium fuselage their size imposed too much of a weight penalty.

- The cabin lighting system was revised to be an LED hybrid (part LED, part florescent), taking some of the 787 system advantages, without revising all the interior lighting.

All these above mentioned decisions were made by mid 2005.

During this time, the 787 was continuing its rapid growth in popularity amongst the airlines and the flying public. It became obvious that the 747-8 interior needed to be more in line with the latest interior from Boeing.

Consequently, the decision was made in the following years to go with a new, more 787 like , sky-interior. This included going to new stowage bins, ceilings and a full LED lighting system. All changes were in line with the 787 interior, the only difference are the retained 747 style sidewalls (because of the installed "old" style windows.)

The 744ER's interior is 777 style. The 748's is clearly different, just look at the handles to the overhead bins.

To answer the OP's question, the 748 DOES have the sky interior. There just aren't pics of mood lighting (which I don't know if LH ordered) and the sidewalls are the same as the 777 (cause they put in 777 windows) so it looks like the old 777 Signature interior, which the Sky interior itself isn't that different from.

Thanks. I suppose the 748i doesn't really have the Sky Interior in the way the 737 and 787 do, rather a hybrid between the Signature and Sky Interiors...

Quoting PanAm788 (Reply 7):

I realise that the handles a different... The shape of the bins is virtually identical though, as are the sidewalls and the overhead panels. The only changes, aside from the handles, are in the entry areas/stairs and perhaps the galleys (no idea, haven't seen any pictures...) I think it's reasonable to say it's 'pretty much identical' when the only updates are the handles and some behind-the-scenes lighting changes. Even then though, QF already has LED mood lighting in the ER (in F/J anyway...)

Thanks for clarifying that. I always associated the Sky Interior just with the mood lighting (I guess as the colours draw your attention) so didn't realise it covered sidewalls, bins, 777-style windows etc.

Looks like LH didn't order mood lighting, perhaps to keep in line with the A380 product which also doesn't have it and to save costs?

While the sidewalls are indeed unchanged, the shape of the bins of the 747-8 is only as identical to the 744ER as the 787's bins are identical to the 777. In short, the similarity is that they're both fold-up style bins. Look closely:

In comparison, the 747-400ER's bins are significantly different. Look at the curvature of the centre bin lids, and where the bins meets the ceiling:

Sorry, I don't agree that they're "virtually identical" at all.

You can't not order it, it's characteristic of the LED lighting controls. All you can do is choose not to use it.

The Sky Interior is a 737-specific product, as on option on 737NGs and standard on the 737 MAX. It is not available on any other Boeing model. The 747-8I cabin has many of the same features, most of which were inspired by the 787, but it is not called the Sky Interior.

Now, I'm not a techincal person by nature*, but from what I know LED lighting is more energy efficient, lighter, less prone to burn out and ultimately cooler than other forms of ighting when in operation.

Seems like the logical choice for the inside of an aircraft, frankly.

(*techincal persons out there, please correct if I am wrong....)

Actually, I think Boeing has retroactively applied the Sky Interior name to the 787 and 747-8i. Expect the 777-8X/9X to have it too.

Since the Sky interior is really just a slight derivative of the Signature Interior that's been flying around in 777's for years, I would say that is false.

I took a look at the pictures from that link. For whatever reason they create a dingy look for the cabin. I did notice the windows had the elliptical Boeing 777 look. Regarding the shades even the 737-800 that we are getting WN/FL have traditional shades however the "window reveal" is ovoid shaped. The outer window frame on the 737-800 is still the traditional squarish version that Boeing used up through the 767.

They are set on yellow. LED's make a very homey yellowish glow.

CXB77L shows the LED's in a much higher color temperature setting in his cabin pics.

The LED's themselves are tiny (a couple of mm across) and lined up one next to the other RGBRGBRGBRGBRGB all the way down the strip. All you have to do is vary the RGB intensities and you can get any color you want.

Another way to tell if the cabin is Sky Interior is to look at the "gaspers" (overhead personal air vents). The new Sky Interior vents look like a flower pedal as opposed to the conventional design.

I know LED lighting is more energy efficient,

A few years back, I was looking into LED efficiency compared to Florescent tubes and the tube was still more efficient in terms of light output per energy used. Things would have changed by then.

LED were always lighter than the tubes, and has high reliability, so they are natural for aircraft use (and now in cars, and refrigerators)

The problem with LED is as you you push up the wattage, they start to put our a lot more heat which needs to be dissipated or else the life of the diode will decrease.

(You will notice the heat sinks on the LED bulbs that you can buy at the hardware store. )
