I have noticed that the cargo version of the 744 doesn't have the elongated upper deck characteristic of the 747-300/400's. Is the 400F basically a cargo -400 with the upper deck of the -100/200 models? It looks like a -100/200 with winglets.

I think they do that to save weight, I also heard the longer bubble increases drag.

I read an article that stated the longer deck of the 747-300F actually helps efficiency. Does anyone else have an answer?

the longer upper deck of the 747-400 does help efficiency, the reason for the sorter upper deck is the floor structure of the upper deck reduces the hight of the cabin meaning larger containers cannot be carried in the foward end of the fuselage, hence the smaller the upper deck the more freight can be carried.

How do you want to load the upper deck??????
No highloader, forklift or beltloader can reach that height.
There is no other use for it than a crew rest area, but just for a few people onboard, the "normal" upperdeck is large enough.

No, i think he means the main cabins height would be reduced if it were to have the Extended upper deck.

Dahawaiian,

Not forgetting of course that despite "looking" like a "747 classic" with winglets....the -400F carries the latest in "glass cockpit" avionics technology.


Visit: Aerowinx.com to see this amazing piece of computer based training software for the 747-400 in action.

I use this stuff, its EXCELLENT.
