The range of Boeing 707-320C is quoted as 5000 nm with 151,5 t MTOW and payload of 141 passengers and baggage (18J+123Y) DC-8-62 range is quoted as 5200 nm with 158,8 t MTOW and 189 passengers. So how does A321XLR compare to 707 and DC-8-62 in more details? Which transpacific lines got served by 707...Jump to post
With the nominal range of 4700 nm, what would be the practical range upwind? YVR-NRT is 4061 nm, YVR-CTS 3726 nm. Is it feasible westbound? The A321XLR should easily be able to fly 4000nm into the strongest headwinds. It should be able to do most routes up to 4300nm From Hawaii the XLR could fly to...Jump to post
Indeed it seems this aircraft's range unlocks those routes, but this is actually not true. This range would be in still air, but the air isn't still. Far from it. In the north Pacific you'd be flying against some of the strongest winds on the planet, which would greatly reduce the aircraft range. I...Jump to post
It should be noted that the A220-100 gets a 450nm increase in range I wonder what maximum range Airbus could squeeze out of a 19-pax, VIP configured A221 at this increased MTOW...taking into account the usual reserves for holding and alternates? :scratchchin: Increased to what?

Although the Spruce Goose is higher and has a bigger wingspan than the An-225, the latter is over 17 meters longer. So, which is bigger?
Nice !! And not very relevant but yet interesting, from now on the world’s largest aircraft has a US flag instead the russian one.

KC-135 does NOT actually have 707 fuselage. Convair XC-99 had a different fuselage from B-36, too.
What should a B-52 based liner fuselage have been like? And how should it have compared against 707?
On arrival, or on attempt to depart?Jump to post

The nacelle is really the biggest challenge. Variable inlets are a must (it can be as simple as Douglas's boundry layer control).

There were built quite a lot of subsonic jets with zero bypass. Yes, inefficient and loud. JT8D has bypass ratio of 0,96. And it is installed on 727, 737 and DC-9 all the way to MD-80 (only MD-90 has higher bypass). Kuznetsov NK-321 has bypass ratio of 1,4, and it is on Tu-160 and Tu-144, both of wh...Jump to post

No harping on fuel use. If I can afford an island in this fantasy, I can surely afford the fuel.
Like you own the turboprop/regional jet and you solo fly it purely for recreational purposes. Is that legal even for recreational purposes? It is a transport category plane.

Well, the Falcon are the only tri-motors in production and have been unique for 20 years now. Do you think Airbus/Boeing/Embraer/Lockheed Engineering is blind to the tri-motor design advantages?

Concorde as is is problematic. Short range and requires a smooth (and long!) runway. Oh, and it is smaller than Constellation.
So basically a widebody.
Two engines are common. So are four engines (A340, Il-96).
The only widebodies to catch eye, besides the already mentioned A380, would be trijets.
It was allegedly a notable design constraint on A380.Jump to post

Belly tanks for the CS100 and its maximum takeoff weight increased to the same as the CS300. This creates the CS100LR. What could the range be? It depends on the payload and flight direction.
