A380...How Big Is Too Big?

Mon Mar 01, 2004 1:21 am

I initially started to respond to the post regarding emergency evacuations on the A380, but felt my response might be inappropriate for that thread. And this topic MAY have been discussed before. If so, I apologize and please bear with me. This is NOT intended to become another Boeing vs Airbus debate. From a SAFETY perspective (emergency evacuations, in flight emergencies, etc) how safe would you feel flying on an aircraft that holds 500+ passengers on a flight of 10-13 hours? I have always been somewhat leery of the A380, as I always felt it was entirely too large. But the post about an emergency evacuation really disturbed me. Am I the only person that thinks the A380 is a disaster of catastrophic proportions waiting to happen after it enters service?

If the plane crashes into the ground at 500 kts, that's that. No change if it's a Piper Cub or an A380, apart from bodycount. But if you are a passenger, you do not much care if you die alone or not.

However, from the viewpoint of survivable emergencies, the 747 was considered safer that the contemporary competition since it incorporated many extra safety features (for example the third wing spar). Larger may well mean safer since there are (normally) more safety features in the form of more redundancy.

All accidents are different and it is hard to really come up with a correlation between size and safety. For sure, if an A380 came apart in flight, the body count would be higher than if an EMB-135 did, but it would be misusing statistics to conclude that the A380 is thus, by it's very size, less safe. This is why for example http://www.airsafe.com calculates statistics based on the proportion of passengers who died, not based on the absolute number. If 30 passengers die in an EMB-135 accident and 70 in an A380 accident (assuming that the accidents are comparable, and that's a big assumption), it can be argued that the A380 is safer because a larger proportion survived. So size does not matter in this case.

Certification requirements are the same for all planes carrying 35 (I think it's 35) or more passengers. So they should all be considered as safe imo.

If nothing else, would you rather go through severe turbulence in an A380 or an EMB-135? Think about which one has more inertia. Thought so.

If an A380 and an EMB-135 landed in very severe crosswind, which would be more stable? Thought so.

If an A380 and an EMB-135 experienced severe wake turbulence, which would be more likely to flip over? Thought so.

NOTE: I am not bashing the EMB-135. It's simply conveniently small for my comparison.


EDIT: Economic reasons limiting size will always be more important. These can mainly be divided into two categories:
1. Limiting size of airport facilities in the form of runways/taxiways/gates and so on.
2. Limited market as size increases, while production costs keep going up.

Just like a big bird in the past may look smaller now, a big bird in the near future may look smaller in a further future.

As the world population is increasing through the eras, so do the dimensions of the planes. Nothing to worry if in the future we will have to be suspended in the air together with more people.

Also consider two things:

1) Mass media loves death and destruction on large scales.

2) When a big airplane (A340, 777, 747, etc) does crash, lots of people usually die.

Based on this, and the fact that the fact that the airlines are a very safe way to fly and do not have many mishaps, when one does happen, it will be beat to death. The US Airways Express Beech 1900 last year is a prime example. While it was relatively small on a destruction or death toll when it would be compared to a larger aircraft, it still was the headline for about two weeks. Even today, you still hear references to it in stories that have developed in the aftermath.

Still, the average passenger could probably not differentiate between the plane that crashed and another one  Big grin

The A380 is going to be more stable than an ERJ-135 because of its weight. Also in case of an emergency the same rules apply to the ERJ-135 or A380 so they are all safe, I would say the A380 will be even safer because of the new technology

Yes.

As other have stated the A380 will be as safe (maybe safer if that's possible) as all current commercial aircraft flying.

Well the engine for the A380 has just left my local Rolls Royce factory here in Hucknall, Nottingham - the picture in the local newspaper shows the engine and it looks massive. It's been here for the last 6 weeks - being tested and we're about 1 mile from the factory - it was really loud! It has been shipped to France to be put on the A340 for a new phase of tests.

I personally would feel safer flying in an A380 than small planes because of its extra safety features and weight. I would hate to wait much longer to board or get off the plane though.

Pffff, after reading this thread, I thaught we would see another A380 bashing session, thanks for clearing things up fellow members  Wink/being sarcastic

All aircraft are safe, else they wouldn't be allowed to fly. Is that so hard to understand? If an aircraft crashes, okay, that's always bad, but in the '70's when the 747 came out, there would have been the same "problem" at that time and it didn't so why would the A380 be such a "different" case. Compared to the 747-400, the A380 isn't that much of a leap forward in terms of passengers carried....

Look at the size of the people inside the fuselage!

Its not that big. Those people are standing behind the railing you see in the background. People should not be that far below the windows. And if they were that small than those doors are absolutely massive. I feel sorry for the 120 lb F/A closing them.

Akumas--I believe that the picture has a trick of perspective in it. The people are actually standing on the platform well behind the fuselage so they look really tiny. If you notice that the people are also just a little bit larger than the windows, so that would lead me to believe that they are far away from the plane or that the windows are really big!

Anyways...I think that in the future the 380 will end up being regarded like the 747 is today...A big plane but not unsafe.

Yes those people are behind the fuselage, it looks like they're standing on scaffolding.

You can see those people standing underneath in orange clothing.... that can give you a more accurate idea..

Akumas you are, of course, correct.
If those people were inside the fueselage, it would mean that the windows in the A380 are higher than a person's height!

Very good post, Starlionblue. Well said.

No, even the people in the orange aren't to scale with the fuselage section. The best way to get an idea of the size is to look at the exit door on the side of the fuselage.

If Boeing ever decides to build the BWB, that will be really big, and it will be very different in the eyes of others than A.net members too. I imagine the authorities would have trouble with that one since they might have to rewrite the rules.

As A388 (nice nick!) says, the A388 not really such a huge leap compared to 707->747. And it's still a tube with wings, conceptually the same as a DC-3 in many ways.
