747 A380 Slide Of Death Photo

Sat Oct 07, 2006 3:30 am

The below photo of the emergency slide on the 747 looks kind of scary. Can a passenger go down that and not break bones? Will the A380s be of the same design? I am sure if it was between death by fire, and taking the slide, I would take the slide, but there has to be a better design.

The point isn't to have a fun ride down a slide. It's to get to the ground as fast as possible, while limiting injuries. I may sprain my ankle, but it is far better than burning alive trying to get out through the bottom level.

IIRC, when the Gimli Glider (Air Canada flight 143) ran out of fuel, glided to an abandoned airstrip, and screeched to a stop with a collapsed nose gear, the only injuries occured on the evacuation slides.

I suspect this was a result of the nose gear being collapsed. The rearward section of the airplane was higher than normal, so the slides hung at an angle that was steeper than normal.

I've stood at an open door on a 747 upper deck, and I can tell you...the main exit would have to be blocked by a wall of flames for me to jump.

I wonder how many of the 34 injuries that occured during the max-pax evac test on the A388 came from the upper deck slides versus lower. I don't think I've ever seen it spelled out...perhaps intentionally?

Good question. I'd love to see the data.

Slightly off-topic...does anyone know whether the A380's upper deck slides will the have covered 90-degree corners at the top? There was talk of including them to prevent evacuees from seeing the view down until they've already jumped onto the slide.

Question...(relating, to the photo). In a freighter, who arms the evac slides? I realize that in a 747, the upper doors are *always* armed, but in every other airliner model, this has to be an issue...

I would think a better design would be some kind of tube with an huge inflated pillow at the bottom. Like the kind you see kids bouncing on at carnivals

The slide shown above is almost at a 90 degree angle to the ground with a very little lip or landing zone at the bottom. I don't see how anyone can go down that with out injury.

People are supposed to go down the A380 slides two abreast. Imagine pairs of people running out the door and jumping side-by-side.

I really doubt it's close to 90 degrees. It's probably steep, but not that bad.

Correct for the Gimli Glider.


It is an accepted "fact" not widely advertized by the airlines that an evacuation will probably involve a couple of sprains and maybe a broken bone or two. These are seen as preferable to the alternatives. You know, the charred flesh and stuff...

You are being tricked by the optics of the camera.

When using a telephoto lens, the objects depicted appear compressed along the direction in which the photo is taken, i e flatter than they actually are. This makes the angle of the slide appear a lot steeper than it actually is.

That, however, does not change the fact that a few injuries are expected during any emergency evac. That's why they are a bit reluctant to blow the horn at times. They know that there'll be a broken bone or two, a few broken wrists, hips, sprained ankles etc.

I would imagine elderly people would have abit of a problem even thinking about going down that slide. I can picture an elderly granny standing at the top, repeating over and over that she can't go down. She would end up holding people back up behind her and the flight attendant can not really just push her down.

Which makes me wonder, is there any rules about flying on the upper deck of a 747?

In case there is an emergency, all people on the top deck should be able to, if required, go down the steep emergency slide without much thought.

Yup, there have to be standards for that stuff when evaluating the evacuation methods for the planes, etc...I am pretty sure the acceptable maximum in a drill is 5%. That means the 34 injured pax on the A380 are well below the threshold for how many were in the plane (almost 900?)...a pretty impressive showing considering you had hundreds of people falling from many feet up in the air from that second deck. Good job on Airbus.

So true. And it is also understood that any evacuation is a suboptimal outcome, with no way to plan for every eventuality. For example if the captain parks her next to a tree.


As I understand it, the slide isn't exactly slippery as an oilslick either. I'm pretty sure it has some friction so as to limit terminal velocity. I think that's one of the reasons you should hold your hands on your chest. It lessens the risk of friction burns.

Come to think of it, that was the other main cause of injuries on the Gimli Glider evac. Apparently, there's enough friction to cause very severe burns that essentially tear off exposed flesh.

I shudder whenever I see people flying with flip-flops, high-heels, skirts, etc. Imagine having to A) Evacuate, and B) trudge through and wait in ice, slush, and snow after the evacuation while wearing such things.

Quoting Airfoilsguy (Thread starter):
The below photo of the emergency slide on the 747 looks kind of scary. Can a passenger go down that and not break bones? Will the A380s be of the same design?

The slides are of different design. In fact, the A380 upper deck door is LESS high than the B-747 upper deck door. I remember reading one accident report where a B-747 PIC or First Officer broke his collarbone because at the end of the UD slide he fell off the slide.

The A-380 UD deck doors are designed so that passengers do not hesitate before they start the descent...the slide is designed so pax cannot look directly down to judge the height and thus are sliding by the time they realize how high they are.

An interesting feature of the new A-380 slide is that they can deploy several more feet of slide in case the door detects an unusual aircraft attitude when it is open (i.e. the UD doors in the front of the plane during a nose up landing will deploy several more feet of slide to ensure the slide touches the ground.)

I've been down a B744 UD Slide Before, its fast, but not dangerous... Not in the slightest... If you keep your whits about you and put your feet down infront of you and continue running as you hit the ground, you'll be FINE!

If you like my friend on the other hand, DONT stick your feet out ready to be walking on when you hit the bottom, you'll end up on your back and that IS painful because the 2 or so ft from the floor to the slide surface is a fair drop even when you're NOT doing speed!

Anybody know the inertia reels attached to the cockpit emergency hatch of the 747 (UPS used them also for their 757s)?
You were supposed to don a harness looking like a diaper, hook that inertia reel to the harness using a snap hook and then jump out of the emergency hatch. As one F/E on a safety briefing before a jump seat flight told me once "you go down like a barrel of bricks"!  Wow!
On the Channel Express A300B4s they didn't even had the harness, you were supposed to grab a reel by the handle and make sure you went out of the cockpit window feet first.

The 747 also had only a hand reel, no diaper/harness. You grab on and slide down the side of the fuselage. I think they are all the same. Its still better than the rope you slide down on most airplanes. The inertia reel at least wont give you a rope burn.
