Airbus Window Line

Fri Jul 16, 1999 11:33 am

Why, on some Airbus aircraft such as the A330, does the window line slightly go up towards the end of the fuselage? The window line is completely level and then noticibly goes up at the end. Why is this??

This is to maximize the cargo bay volume. Because the belly of the plane rises up to meet the top, the cargo bay will get smaller and smaller. So Airbus decided to angle the latter part of the cabin floor (together with the window line) upwards to still get some extra volume then normal.

You always hear people saying how much cargo volume the Airbus family have. But remember that if Airbus has a bigger gargo bay, who's going to have a larger cabin.....
I always found this to be a kind of lousy idea, because if you buy an airplane, it is to fit the forecast amount of people on that route precisely in that plane.
For example my airline calculated that I would need an airplane with 300 seats to fly this route. So I buy a plane with 300 seats. If you fill that plane even near the 300 seats, you would have already run out of payload to fit extra cargo in that belly, so of what use would it be.
The only thing you'll notice are passengers complaining about the cramped cabin, because you buyed a plane with a slightly larger than normal cargo hold that you can't use anyways.

That's what I think anyway. I bet there's someone out there who disagrees......

Intersting about those rear cabins. Wouldn't that make it difficult to make the plane into a freighter. I guess you could put the extra cargo into the lower hold instead of the main cabin, but I think that would make more of a hassle to load and unload the plane. You would either need more time to load/unload the plane or need two ground crews. Maybe they were trying to solve that problem of people taking too much luggage. The only problem would be that you could get all the luggage aboard but some passengers would have to get off.

Just my two cents...

I don't know if the weight of the passengers would be enough to invalidate the cargo capacity, also depends on the stage length, outside temp, elevation of the runway etc. Having a large cargo bay definitely makes Airbus a better bet than the 767 - incredible arrogance of Boeing to build a widebody trunk liner which can't take LD3s. And the rear cabin isn't cramped, in fact cos it's slightly rising at the back you can see a long way forward, slightly over the top of the rows in front, making it feel less claustrophobic. And when an airliner is in the cruise, there is a slight nose-up deck angle which means that the rear cabin is actually parallel to the ground (as opposed to slightly 'uphill').

All this is very nice, but remember one thing. Airlines won't sacrifice that extra bit of cargo space for a smaller cabin. Remember that not only is the latter part of the cabin floor pushed up, but the whole cabin floor is pushed way up in comparison with the 767-300 for example.
If an airline wanted so desparately to add extra volume they would either get a dedicated freighter or a combi.
I will bet you that no airline ever decided to go with the A330-300 because of the larger cargo volume. They did so because they either got a much better deal or they found the A330-300 to just be a better performer than the B767-300 or a combination thereof.
