B767-400 Vica Versa B777

Tue Feb 03, 2004 11:05 pm

Hi everyone,


I was just wondering and asking myself where is the real difference between the B764 and the B777 ?

I am not talking about the look, inside cabin etc...

What I mean is the technical differences so as technologies, engines, features, etc...
Except the numbers of the model (B767/B777) where are the changes?

Any answers or ideas ?

Major differences. While the 767-400 has a number of engineering upgrades to reduce costs over previous versions, the 777 is an entirely different generation of technology. The basic 767 wing was designed in the mid to late 1970s. The 777's was designed in the late 1980's, early 1990s, and is significantly more efficient. The 777 was completely CAD (computer) designed.

The 777 is Fly-by-wire the 764 is not. One obvious technological difference.

OK thanks, now I already know some differences.
Any others?

Im sure this is like comparing the A300 to the A330, anyway the engines.

B764:

P&W PW4062 63,300lbs
GE CF6-80C2B8F 63,500lbs

B777:

P&W 4098 97,900lbs
RR Trent 892 90,000lbs
GE 90-94B 93,700lbs

All new engines

The 772LR's, soon to be world's longest ranged commercial aircraft, range will actually be 9280nm (which outperforms the A345 by 610mi  Big thumbs up); and its MTOW will be FARRRR above 545k lbs my friend....

...or heck, above any twinjet ever made, should a customer demand it  Smile

I wonder what happens if those (only) two huge 777 engines fail while flying over the pacific. Then you get the worlds biggest glider

Im all for Airbus, but an A330-200 did that over the atlantic not so far back  Sad

Adria,

World's biggest glider was a 747 with quad engine failure...

...perhaps it should be added because the aircraft ran out of fuel due to ineptitude on behalf of its pilot, and especially, its maintenance crew-- something that would have rendered even an 8-engined B52 into a glider  Insane

It ran out of fuel because it had a fuel leak and the pilots tried to pump fuel from the left tanks into the right. The fuel never made it and went overboard instead, i already know.
If they hadn't have done that wouldn't they still have had one engine?

Regardless it was still a big glider which granted could happen to any aircraft.

...ever stopped to think *why*? Might have something to do with the maintenance crew placing an L1011 fuel cap/gauge on the A330  Laugh out loud

"...ineptitude on behalf of its pilot...."

I would call Captian Pichet (spelling?) a hero. It wasnt his fault that there was a maintenance screw up. He saved hundreds of lives, there is no ineptitude in that. (Mind you, he technically may have made a mistake by transfering fuel into the leaking wing, but he didnt KNOW there was a leak. It was standard procedure to do what he did. AND, even if he hadnt, its likely that they still would have ran out of fuel anyways.) He is certainly a hero in my book, and everyone who was on that flight will agree with me. That I know.

"I wonder what happens if those (only) two huge 777 engines fail while flying over the pacific. Then you get the worlds biggest glider" <====what is the likelihood that this would happen? Chances are slim to none. What happens to an A300, A310, A330, 757, 767 if their engines fail in the middle of the Atlantic?  Smile  Big grin

The Boeing 777 has a much wider cabin, much more powerful and bigger engines, much longer range if an -ER model, is about 9 feet longer, has six-wheel main landing gear trucks. Also, the 777 has a much more 747-like size to it than the 764ER. Also, the 777 has a perfectly circular cross section, whereas the 764ER retains the traditional Boeing "double-bubble" shaped fuselage. In conclusion, while the same aircraft, and while the 777's design was based off the 767, they are two completely different aircraft. Need I say more? The looks, plans, technical specs clearly show a different fairy tale of two different aircraft, brothers borne at the same time by their mother, Boeing Big grin
