I was wondering why there is a curve upwards of the rear windows on Airbus widebodies. At first I thought it was the pictures I was looking at until I saw one myself. If anyone can explain my curiosity would be gratefully sated.

Being from Boeing, I am happy to say that this is due to an Airbus SNAFU (you can also see this on the IL-86). Airbus located the floor too low, so that near the rear of the plane, the underfloor cargo space did not provide enough room for the LD3 cargo containers. Instead of raising the entire floor structure and further reducing the passenger cabin volume, it was decided to simply raise the floor at the rear of the aircraft to allow enough room for the 64-inch tall cargo containers.


If it was said by us, then it must be true.

To add a little more to Liedetectors' answer: Airbus decided to upsweep the rear fuselage, instead of using a conical close out, like on the 757 and 767. This led to the problem that Liedetectors relates. This upwards bend in the floor makes loading main deck cargo on freighters difficult - the rear pallets have to be pushed up the incline.

How steep is the Taper & what would be the Height difference.

This Taper makes the Windows look weird.Is it on all Airbus Widebodies.
Was there an Attempt to raise the floor height later on.

An incidental benefit of this is that the deck is nearly level in flight, back at the aft end of the cabin. Flight attendants start out of there with the cart and soon find themselves pushing it up hill.


Happiness is not seeing another trite Ste. Maarten photo all week long.

At normal pitch up during level flight I thought all F/A's had to push the cart "uphill"...whatever a/c they were flying in.

The Airbus taper maybe only makes it look worse...or is it really steeper ? One for the Airbus jockeys to answer methinks  Silly

Sooo... you are saying that Boeing unnecessarily reduced the passenger cabin volume in the entire cabin, just to be able to fit ULDs in the tail and have a level floor? Smart move! Yeah, they DO seem cramped...  Wink

Tongue-in-cheek, aircraft design is all compromises all the way - and there's rarely a 'right' answer to any given choice.

I thought I was doing good trying to avoid those airport hotels... and look at me now.

I first saw this on an A300, to be honest as a passenger you don't notice it when onboard.


After Monday and Tuesday even the calendar says WTF...

Actually, you kind of do. I sat in the last row of a AA A300 one time and i definetly noticed the floor ramping up at the back. Good thing it didnt cut into the head room tho.

I too have noticed it, but on an EI A330-300. Though, I thought that I would have noticed it more looking at the outside because it looks more of a rise than it really is onboard...  Smile

I noticed it when I sat in the last seat of AR's 342, IIRC it was 42 F.
It is like in a movie theater, sorta.

The ramped section often comes across fairly obviously in cabin shots taken from the rear of the aircraft, although not always:

I believe the deck angle is only something like 2-3° - less than it usually appears from the outside. Over in the KLM A330 thread in CivAv, I wondered why airlines don't tend to match their cheatlines to the windowline to disguise the rise a little.

Just another couple of photos to illustrate how a sloping rear floor sometimes is, and sometimes isn't, obvious:
