1) The A320 does not have a circular cross-section, although many people mistakenly think it is ;) The A320 cross section is slightly taller than wide. cudos to you. but not enough to really matter. The A300/A330/A340 is probably the optimal circular cross section if you want to use LD3s (side by s...Jump to post
How much of that extra volume in the circular version is useful though, versus just being wasted dead volume? if you look at the A320 X-section there isn't much wasted volume. If any. A flat oval may place pax more efficiently ( though I doubt that) but you loose any sane storage for bags. It would...Jump to post
HAM has a suburban train (S-Bahn) link. Every 10 minutes, takes 20-25 minutes to the city center and central station.

Yes, but we are talking about an MOM where the whole aircraft is optimised for a particular route mission in comparison to an A322 where the design of a new wing has to be compromised so that it can fit an aircraft originally designed to fly 2000nm.

I think airlines think of cheap as cheap in 20 years of operating cost and rest value too. Most certainly. And if an airliner is made of material with a fatigue "floor," then the reseale value definitely becomes an issue because the airframe itself is "immortal." Pretty neat, hu...Jump to post

Is it possible to accommodate a maximum of 1,000 passengers, on a reconfigured A380 Plus. You'd have to put the last ~150 pax in a trailer ( A380-800 evac limit is 873, pax, FAs and pilots). Hmm.

No, and that's not what's proposed. Exchanging the center wingbox and wing and everything in/on, is a different approach. The A300, A310, A330, A343, A346 demonstrated there's a lot you can do with length, wings and engines. Same for the 737, DC9/MD80 e.g. this may be a misunderstanding on my side....Jump to post
I don't know the "per meter length weight"; what I mean is the 787 is so much heavier than the 767/A321LR that you cannot just scale down the 787 and morphs it into a MOM aircraft. Well, we do have OEW for A300B123, A310, A300-600 and we have OEW for the A330 types. If we assume the longs...Jump to post
why would you not optimize the fuselage for the lower MTOW? Fuselage weight is determined by structure requirements for the payload. fuel for range and structure to carry both then dertermines MTOW.

Did Boeing ever spent a dime on this? Why should they? Boeing does not want the plane to be found. Current information points to rogue pilot, so new information can only harm them.

Actually, every rudder induces torque to airframe part it sits. You cannot turn airplane with rudder without torque exerted from the rudder. My guess is that the OP was thinking about introducing some roll torque (longitudinal axis) into the plane while the primary purpose is torque around the vert...Jump to post
But the 787 had the requirement of LD3 containers. The787 is as narrow as it can be to achieve that. In reality it's maybe 4-5" too narrow for the now favored 9Y. going down to 222 inches still fits LD3 ( see A300.) obviously Boeing wouldn't copy that X-section. Making the 227"/237" ...Jump to post
I don't think that is supported by history. The early Boeing jets like the 707 and 727 were both fast Mach 0.85 cruisers. The later generation of 757 and 767 jets slowed down to Mach 0.80. Boeing crept back up to Mach 0.84 with the 777 and now is returned to 0.85 with the 787. The conclusion I woul...Jump to post

Somebody told me the fuselage is a limitted part of total aircraft MTOW.. say 15%. So saving 20% there is valuable, but not very valuable.

Personally, I'd add a Z axis showing number of airframes ordered. It would address the problem that this chart (which really came from AvWeek, using Boeing's data) has, showing the 767-400 and 757-300 with a same sized dot/square as other products that sold many times their number.
