It doesn't look so bigger,
how much are 80 inch and 60 inch in meters ?

OK, i found this "Lenght Converter"
http://online.unitconverterpro.com/comm ... ength.html

so 60 inch is 1,524 meters
and 80 is 2.032 meters

wich means that the 747adv will be 3,6 meters longer

This increase in length is sufficient to increase the 747 capacity to a close "sub A380" level. The biggest improvement they can add to this list is the composite hull of the 7e7 but with 747 dimensions -> that would guarantee a renewed interest by many airlines. The current mods just look like a refurbished 744, and not a new aircraft based on an award winning design/concept.

I'm sceptical,

Hello All of you!

so... nothing new....... I Just don't really believe that this 747-adv project is serious, it's like talking about the 747-600X, the Boeing 17 (civile version of the c-17), or the Antonov an-426.... hehehe, but i really want them to build it

With the interest currently at a high level in this Aircraft, and the demand for this type at a peak, one can almost bet the farm this Aircraft is going to fly.

The argument being bandied about that this plane is old, and is past its prime don't hold water. The design was far advanced for its time when it rolled out the door at Everett, and with the improved engines, composite additions, and other improvments it can hold its own against anything in the air.

Freighters love this plane to death, and they are the determining force in reviving this Aircraft, JAL, Cargolux,Korean Air, are all operators and are in line for more.

The economics are simple! this plane has next to zero development costs, they are dirt cheap to buy, operating costs will be cheap as well, no new training required, ground handling equipment will be unchanged, and the Aircraft will operate at any Airport it currently uses.

Nippon Cargo is another one.
Fedex?

I really think the B747-Adv will be FBW finally. As I said earlier, I started a 3-views draw of it but failled to achieved it! i hope I'll work on it again to be on time for the official lauch...

Regards

Seb.

soory to ask but what does FBW means? You did a sdrawing of the plane ? Show us !!!! please!

Knight255 · Post by **Knight255** » 08 Sep 2005, 01:44

FBW=Fly By Wire, meaning that the control inputs made by the pilot go to a computer and the computer sends a signal to hydraulic actuators to do what the pilot says it should do (that is on Boeing planes). This contrasts with normal hydraulic systems where the pilot puts in a control movement which moves actuators directly with the hydraulic system. Most fighters these days are FBW because they are so unstable they need the computer to assist the pilot. I hope this helps.

Thank You!!! in a way i prefer non FBW, because, what happens if there is a bug with FBW ? or a CPU shut down ? It's very scary!

Knight255 · Post by **Knight255** » 08 Sep 2005, 03:15

No need to worry, there are many backups!!

Think of it this way, what if there were a hydraulic leak in non FBW planes??

Hello there,

I've got a bad and a good new for you, folk:

The bad one is it will take me too much time for to achieve my 3v 747-Adv draw.

The (very) good one is you don't need to wait anymore for it since I just found better.

Enjoy!

Seb.

WOW, Thank you very much!!
They did it in July 2003 already ? So why are they taking so long to announce its consruction. I can also sea in this drawings, that the cargo version will be very different than the passenger version...

I think most of the actuators are controlled by cables which are strung between the servos & the actuators

Even on a Fly By Wire aircraft , you can still have hydraulic leaks because all flight controls are still actuated by hydraulic actuators, like on the A380 the pressure is 5000 psi instead of 3000 psi on most commercial airliners ,so a small leak can create a hazard situation, only a few small aircraft have electric actuated flightcontrols , like ATR 42.
Conventional aircrafts are also fly by wire , but its thick steel wire

I was trying to put things into perspective, but thank you for pointing out what I missed.

THere is an small article on this month's "Airliner World"

about the B747Adv: Here is the title:
Cargolux Emerges as Possible B747Adv Launch Costumer

and the list sentence of this article is:
Boeing Sources have told "Airliner World" that the project could be launched as soon as this september.

Here's a link to the picture of the world's first B747-400SF

It looks like the 747Adv will indeed be approved...

I dont' know but some airlines, notably Singapore Airlines, has clearly said that their A380s will not carry a lot more passengers, but to offer passengers a much nicer travel.. while some other airlines are of course taking all 800+ seats..
I don't know but this is beginning like battles between car makers... Like when Mercedes introduced its Mclass, BMW followed with a X5; when BMW re-introudced the 6series, Mercedes followed with a CLS... That is probably OK because there are just basically infinite car buyers out there compared with how many airliners there is out there...

For Cathay, I have no idea why they are not replacing some of their 744s with A380s... their long haul routes like HK->LA should be replaced with A380s and also use the A380 as an ultra high volume to fly some routes from Hong Kong to Japan, China, Taiwan instead of sending like 5 A333s per day to each destination...

As for Qantas, they have lots to reason to buy 747Adv as well as the A380. They will probably replace some 744 flights with their new A380s, but don't forget they still have lots of 743s which are pretty darn old that flies between NZ and Australia and other close destinations... don't know, but A380s for its expensive purchase price, seems like it will be served on very profitable routes only in the next few years...
