I myself think that both A 340-600 and B 777-300LR look great. However, does anyone know which one is bigger? Also which one has a longer range?

I think the B 777-300LR is bigger. Right? Slightly bigger I mean. Can anyone confirm this?

Figures available at www.boeing.com and www.airbus.com. This <> doesn't work for some reason.

The A346 is about 1 meter longer than the B773.

Rangewise, the B772LR beats the A345 by some hundred nM (right?)

777-300LR

Span - 64.8m
Length - 73.9m
Height - 18.6m
Range - 13,330km
Speed - Mach 0.84 (Cruise)
MTOW - 341,105kg

A340-600

Span - 63.45m
Length - 75.3m
Height - 17.3m
Range - 13,900
Speed - Mach 0.86 (Max)
MTOW - 365,000kg

As you can see, the A340-600 is longer, with a higher Max Take-Off Weight, slightly longer range, simmilar speed, and slightly smaller span and height. (Sources - Airbus & Boeing websites)

The 777-300ER is about 1.5 meters shorter, but is 0.5 meters wider. The Airbus carries about 20 more people, but expect the seats to be a bit narrower.

The range of the 777-300ER is given by Boeing to be 13,330 km, or 8,200 miles - I assume that's with a full load, as Boeing does not give any distinction. The A340-600 gives a range of about 6,500 miles with a full load, 8,600 miles with a full passenger load but no cargo, and 10,100 miles with no payload.

The A340-600 is the longer than any Boeing aircraft as well as the Airbus range.

Why would the seats in A340 be narrower? i thought although B777 is wider, it has more seats in a row 3-3-3/2-5-2 vs 2-4-2.

It seems that they are about the same in terms of size. How about the B 777-200LR? I suppose it has the longest range of all right?

sia772er,

If the the A340 is only a meter or so longer, but narrower, and carries 20 or so more passengers, something has to give. Either the airbus must have narrower seats for a 9-across config, or they did their estimates spacing their rows closer together - i.e. less leg room.

Cfalk: Exactly. Airbus certainly can't squeeze 20 or so more passengers into 1 metre, I think AI most likely has to compromise seat width.

The Airbus is longer I know that much.

a) Remember the 773´s theoretical max number of pax is 550 - as much as a 742´s. Unfortunately, I´ve never heard this number for the 346, but it will be certainly LESS, due to the narrower hull (3-3-3 as opposed to 3-4-3 [or 2-4-2 vs. 2-5-2/3-3-3 in a more humane environment]).

b) There are two armrests between seats E and F
(IAICI IDIEIIFIGI IHIKI) so, unlike today, every pax has one armrest completely to himself.

The pax number in B777 may be less because of the seating arrangement.
B777:
three class config.:
first class: 30 passengers, 60-inch pitch
business class: 84 passengers, 38-inch pitch
economy class, 254 passengers, 32-inch pitch
Two class: 479

A340: (2-4-2 in economy)
Three class:
12F at 62in +54B at 40in + 314Y at 32in pitch
Two class:
419

I guess B777 is still bigger then...

As far as speed goes...the one from Airbus says M.86 max, while Boeing just says M.84 Cruise. So what is the cruise of the A346 and the Max of the 777? I seem to recall that the cruise of the A346 was a significantly slower than the 777. Does anyone know if this is true?

According to Boeing's web site, they claim the following:

One 777 advantage that pleases passengers and airline accountants alike is its speed. Traveling at a cruise speed of 0.84 Mach, like the current 777s, the longer-range derivatives will cut approximately 30 minutes off the flying time on 16- to 18-hour flights as compared to the A340, which travels at a speed of about 0.82 Mach.

In addition to cutting flying time, the increased speed of the 777 often gives it preference in obtaining earlier approval for climb to higher altitudes, resulting in a noticeable economic advantage for airlines.

Going head-to-head with the Airbus A340-500/-600s, the Boeing 777 longer-range derivatives demonstrate seat-mile costs that are 14 to 18 percent better. Fuel burn is considerably lower for the twin-engine 777-200 and -300 longer-range derivatives, 21 to 22 percent lower than the A340-500/-600s.


Of course Airbus will advertise their Max speed rather than cruise speed. I don't know what a 777 has been clocked at, but 747s have been known to cruise well above 0.90 Mach, although they usually dial it back to 0.84 or so for fuel economy and airway spacing reasons.

Don't belive what is written on a Boeing homepage. Do you think thay are going to confest that Airbuse's product is better. LOL As much as I know, A346 also travels at M0.84.

Yeah, I think so too. After so much about the A340's low speed has been critisized, Airbus must have done something. By the look of the A346's photos, its engines look pretty huge, so I highly doubt they're underpowered.
Boeing really has to do something about it...and FAST!!!
