I am sure this question has been asked many times on the forum but I just dont know what keywords to type in to find something like this. So I will ask myself. Why does the rear section of larger Airbus aircraft slope up? It is most obvious by looking at the passenger windows. My only thoughts are to give a little more tail clearance for say maybe tailstrikes. I dunno, someone fill me in here.
Thanks a lot

This has been discussed, but I wouldn't know what to type in either.
The answer is that the tails of airbus' aren't actually sloped up; it's an illusion. It is due to the shape of the aircraft's tail view from above that actually causes this illusion. Airbus jets are wide from front to as far back as possible. This is to allow as much space inside as possible for cargo, seats, etc. When seen diagonally from the front, it looks like the windows in the last few rows to slope up.

That's it: to accommodate standard LD3 cargo containers in the cargo holds till all the way at the back. Flight attendants having to push trolleys from mid galley to rear galley can tell you that it is NOT just an optical illusion, although it is most obvious when seen from outside at an angle of about 45 degrees (dunno why...)
I can't say this is my favourite airline, but this photo best proves the point above, so...
On the ground the floor is flat (level) but in flight when you go from the back to the front you would be going up-hill. This is the case in (amongst others) Boeing, Lockheed or McDonnell Douglas aircraft... The Airbus widebody aircraft floors however level off in flight and sort of form a "dish" shape and reduce the angle. This is easier indeed for example to walk OR to push trolleys around.

I think it's just an optical illusion.
Draw small circles on a piece of paper in a perfectly straight line. Then bend the paper (in the way the rear end of an airplane bends) and try looking at it from different angles. You will notice that the bent part looks as if it is slightly higher.
Maybe it's just me. Try and let us know what you saw.

I remember when Lufthansa first took delivery of their A340s.
The front landing gear leg compressed to a greater degree than anticipated, which, coupled with the slope of the airframe, meant that Door 4 was too high above the tarmac to be reached by Lufthansa's catering trucks.

A lot of interesting yes's and no's but still no answer as to why?
Okay firstly yes it does slope upwards on all A300, A310, A330 and A340 aircraft. No it's not a design fault and not specifically to house LD3's or to get the FA's to push trolley's up hill.
It's a simple matter of space utilization. Sloping the floor upwards slightly utilizes the maximum available cabin width in that part of the aircraft.

I thought it was for the placement of the rear galley (sits basically inside the tail cone). If they didn't ramp the main-deck floor then they would require a step up into the galley. I think the FA's would prefer a ramp to a step.
As for the windows - I think they keep them level with the floor for esthetic reasons only. If you have ever sat on a CRJ-200 you will know how uncomfortable it is to look out of windows that are down near your seat belt.

I do fly on the A330-200 2 or 3 times a month and I can say that there is no step to get to the rear galley, no problem to push a trolley from there to the cabin. Great plane to work on depend on the accommodation made by the airlines. Corsair 355 pax, AF 211 pax, Star 365.
