A-380 Overwing Exit Question

Thu Nov 01, 2012 4:02 pm

One of the things that intrigues me so much about the A-380 is the unique wing shape, especially how it appears from the back. For some reason, to me at least, it's very eye catching. However, I noticed something in this photo that I hadn't really ever noticed before:

There seems to be a distance of 6-7 feet from the sill of the overwing door to the upper wing surface.There does seem to be somewhat of an outward slope below the door, but from the image I cannot make out to what degree. How exactly is the evacuation handled through this door, i.e. are there ropes etc. to assist someone out this door? With that kind of a drop on to a sharply sloped surface, I can see there being some injuries caused by an unassisted exit. Perhaps I am missing something about this particular exit.

The slide pop's out over the wing and guides people to the rear over the trailing edge of the wing. It is just visible in the photo on the lower half of this page.

This.

It's probably a similar design to what the 747 & 773/W family utilize for their overwing Class-A's. I would hazard to guess that the area behind the slide panel is a little larger than your standard Door Bustles on the other M doors, to accommodate the somewhat kinked slide. We get a few daily 380's at work; I'll have a closer look tonight for you there...

When fully inflated, those slide are more than capable of supporting the weight of several humans over the distance.

Interesting, I knew that they stored it in the fuselage (as opposed to the door), but it makes sense! I see that the A320 used the same method as well - does anyone know if the slide extends when the doors open, or is there another control inside?

Ok, that look awesome! Interesting evolution of the slides!

Its fully a slide from the door. It is however the only door onboard that isn't a slideraft so it can't be used in a ditching.

Its automatic if the door is armed however this is also a manual inflation button.

I doubt who will be willing to use the overwing exit of DC10???
The slide is directly over the wing and the engine!!!

Many incidents are related to the engine (etc. engine on fire)
The exit wil

I think it will depend on the pilots' judgement call. They should know if there's an engine fire or even a engine malfunction.

That way or another, the pilots will need to know the location of a problem (e.g. the right MLG is on fire, leading to an exit on the lefthand side).

Repacking (and deployment) of a BA 747-400 shown in this BBC Documentary.

Clip starts at the part showing the slide deployment, but the whole documentary is available in the link. Well worth watching if you have a spare hour.
