Hi, I'm new here and haven't really read all the postings about A380, and so please forgive me if I ask a question that had been discussed
previously. I have a few questions about A380 that seems to not be covered in news articles.
Hi!!
1) Given the size and weight of A380, if it makes an emergency landing at some high-and-hot airports (e.g., Denver), can it take off again?
In most cases, yes. Basically the A380 is an upgraded A340 ER series (well, its a lot more than that, but the A340 ER is a flying testbed for the
A380 and the A380 wont be that much heavier in most configurations).
Take off speeds are generally less than landing speeds, and the A380 has a huge wing area to generate needed lift.
Bear in mind this question also stands for the 747, which can land at most strips but not take off again.
2) Has Airbus discussed any special plans to group luggages? I already have a hard time finding my luggage from a B-747 flight, imagine a flight with
200 more people.
Yes, as we speak the 'hub' airports (Heathrow etc) are being updated to accomodate the massive amounts of baggage. Generally the idea is that the
plane is operated as two seperate flights to the same destination. The upper deck is booked in under one flight number and the lower deck under
another, with the baggage for both in different holds (front and rear).
This allows the upper and lower decks to be serviced at seperate luggage carousels at arrivals. And I see no reason why it shouldnt work
3) While A380 can carry more people and thus reduce the number of flights needed to carry the same number of people from one hub to another, its large
size would spell problem for some taxiway operations. So will non-A380 airlines be negatively impacted at airports without reconfigured runways?
The A380 is generally only going to be flown to hub airports, and thus there are few that arent currently preparing for the A380. Also there should
be no further needed space than the A340, which currently operates to these airports, the main consideration is the load bearing weight of the
taxiways.
In general, if it can take a 747, it should take a A380 is the rule.
4) If I were a terrorist, A380 would be my weapon of choice. It has a lot more fuel capacity than 767 or 757 used on 9/11. Are there any special
mechanisms to prevent someone unauthorized to take control of aircraft?
600 passengers?
The main reason 9/11 worked was because it was pretty much unprecedented. Up until then the standard response taught to passengers was "sit tight,
the hijackers will land the plane and demand stuff. Negotiations will happen, and you are better on the ground than in the air in any case."
The flights involved in 9/11 were also not full, with most having less than 70 passengers on board which were more manageable.
It would be pretty much impossible to fight off the 600 passengers who all now have visions of you flying them into a building. 9/11 changed the
world, the passengers will fight back now.
5) I doubt any airline would put in restaurants or other stores in A380. All they want is more seats so more people can be flown for $. Has any
airline actually stated those retail plans?
As someone else said, no they havent. But the same has happened to all planes released pretty much

The 747 was supposed to have bowling alleys,
cinemas, saunas etc in and few of those ideas happened!
6) Can A380 fly on just two engines? How about two engines on the same side of the aircraft?
Yes it can, and it can even fly on a single one for a short period of time. Having both engines on the same side of the aircraft is slightly less
efficient than one on each, but it can still fly. This is a UK Civil Aviation Authority requirement for the A380 to operate out of Heathrow, the
plane has to be able to loose 3 engines on takeoff and be able to come round to land safely.
7) How in the world does Airbus expect people to use the emergency doors from the second deck? I heard they requested computer simulation because
they don't want to test using real people.
They are using special slides using a different high pressure gas than the lower deck ones, to maintain rigidity for the full 4 minutes required.
(although both the CAA and the FAA require you to empty the plane in 90 seconds).
As far as I know, the rating needs to be done with real volunteers, as theres no way to really simulate 'panic' or confusion except with real
people.
Interesting tidbit: the Boeing 777 is rated to carry one less passenger than it can seat. When they were doing the evacuation drills, one passenger
refused to go down the slide, thus the FAA would only rate the aircraft for the number of passengers that got out. Boeing didnt rerate the plane
because of cost reasons.
Anyway, I would apprecate some candid answers to these questions.
