Airbus A380 Upper Deck Safety Question

I was looking at a picture of the A380 yesterday and noticed that the upper deck windows look smaller than those on the lower deck. After searching through Airlners.net for comments on this, I found out that the windows look smaller because they are slanted by the curvature of the fuselage (optical illusion) giving the passengers an upward view. I also read that this slant prevents upper deck passengers from seeing the ground area around aircraft. If this is true, couldn't that pose a risk to upperdeck passengers in an emergency where they have to judge the safety of an exit route by looking out of the windows? I don't think that there is a similar issue with the upper deck on the 747 as the walls are more vertical than on the A380.

Will we be able to choose our seating at check in (within our class of service of course)?
Whether we want to be on upper or lower deck?  Confused



There was a better way to fly it was called Concorde

Well, probably not, as the plane has been granted it's certification, so the authorities like the FAA and EASA don't share your concern.

Cheers!  wave

You can see the ground from the upper deck windows.

Also, the aircraft is certified by EASA and the FAA and the aircraft has undergone a full evacuation test with EASA and FAA officials present.

If you get the chance to choose the safest exit that is. I think in most cases you will be glad just to reach the closest one.


have a good day, Stefan van Hierden

Probably not since you don't get to make that choice. The flight attendants are the people responsible for deciding exit routes during an emergency.

The cabin crew judge whether to open an exit or not and monitor it during an evacuation.

The pax do not make a decision based on their view from the window. The airbus door has a downward looking porthole so the crew member can see the area below the door to judge the safety of that area before deploying the slide.

Kind of like what I wrote.  eyebrow

Boeing 777's and 747-400's have these as well. They are weird to look through because you look in them and expect to see directly in front of you, but something in the glass changes your point of view. Noticed this on numerous 777 and 747-400 flights. Not sure about the rest of the Boeing or Airbus fleet.

I've never been on the A380, but believe me, the 747 UD windows have a terrible slant to them.....

depends alot on how stupid you are. One of the last people out of the upper deck nearly managed to make the trip a very painful one as they jumped out from the door, landed part way down and the slide acted like a trampoline and just came short of launching him onto the hanger floor. Managed to land in the last couple of feet. So if you are very agressive in jumping OUT from the upper deck, you just might have a short flight with a hard stop at the end.

Use them right and it seems that its just fine.

The evacuation slide on the upper deck of the A380 is designed to minimize the pax ability to "look down" and hesitate at the exit. This was an important design consideration that Goodrich had to implement. If the design still allows for pax hesitation, the flight attendant will push you out.  Wink


Release your seat-belts and get out! Leave everything!

I've flown on the upper deck of 747-100/200/300/400 aircraft and I've never noticed any inward slant of the windows. I love taking photographs from the inside looking out and I've had just as good a view on upper decks as I've had on lower decks. I get the impression that will not be true on the A380.

Airfoilsguy is correct. I don't know about the A380 but other planes I have worked on have a prism type window in the door so the view is a close to the fuselage as possible, allowing the FA to determine if it is safe to open the door.

Exactly, there is a video about the evacuation on youtube: http://www.youtube.com/watch?v=weOcrP7u7Y8
