747-8i Door Windows Unchanged From Original?

Mon Mar 21, 2011 7:05 pm

The main deck windows are bigger/more rounded as expected, was curious are the door windows unchanged from the original? From my photos they appear to be but wasn't sure. I assume the doors were pretty much left unchanged from the -400.

I have not heard of a new style of Exit Door being used with the 747-8.

Seeing as how doors are very expensive to design and build I would expect that they would have left them unchanged unless there was a compelling reason to do something different, and I do not know of any.

Even the last 747-400 built in 2009, a 747-400ERF freighter (photo below), still had a main-deck cargo door with plugged passenger windows that dated from the first 747-200 combi built more than 35 years earlier.

No 747s had actually needed the windows for the last decade of 747-400 production (the last -400 combi was built in 1999) but it was presumably cheaper to continue using the door with plugged windows than to redesign it without the window cutouts. I'm not sure whether the cargo door on the 747-8F still has the windows.

Well, in all reality, I believe unlike say the 777 or 767 or even the 787, the 747-1,2,3,4,8i's 5 doors on each side are all very different from each other. In fact, I've heard stories that the over wing exits have a hard time opening when the aircraft is completely full of fuel. (If someone can elaborate, please do). Anyway, I think the 748i's doors are still positioned in parts of the body that allow them to use the same doors that were on the original 747 40 years ago. Now, I wouldn't think it would cost that much to change the window to the 777 style, because I think that's what the new 748 windows are, but when you have to produce 10 doors that are all completely different, I guess it doesn't make much sense. And who really cares anyway? These are rarely used except perhaps 1L/R 2L/R for jet bridges and catering purposes. And then, a window is a just a thing to see through, not something that needs to be more aesthetically pleasing.

On the photo below the difference between the old style door window and the new (more oval) fuselage windows is clearly visible.

The problem is not the opening of the over-wing doors 3L and 3R with wing tanks full. (otherwise the aircraft would never have been certified).
The problem arises when the wing tanks are full with an over-wing door not closed. Due (a small) deformation of the fuselage and the door-frame, you are unable to close the over-wing door. The aircraft wing tanks have to be (partly) defueled to close the door again.

Here is a comparison of he cabin windows of all 747 series up to and included the dash 400 and the new elliptical windows of the 747-8 series.
As shown in reply 5, the main deck door windows are NOT changed and are still of the square type.

Remark : the upper deck windows on the 747-8F are also of the "old" square type (crew rest only !).
