Re: United A321

Until the day the folks at United and Airbus issue a press release, all these talks, models, and posters mean NOTHING.. I know some people on this site have this fantasy of a UA A321NEO, but it wont be happening anytime in the future.. You better inform United about that.. http://www.airliners.net/...

Re: Which Frame Will Be More Efficient....The A35J or the 779?

Why obviously? What facts do you have to back that up? I didn’t realize that a fuselage design was the driving factor in airplane efficiency. I’m guessing you know little to nothing about the 777X design. How do you know that Boeing tried to distance the 777X from the A350? Do you work in Boeing Ma...

Re: Which Frame Will Be More Efficient....The A35J or the 779?

The A350 obviously. It's an all new design, incorporating decades of design advances. The 777X, even with a new wing, will still be a compromise with a 25 year old fuselage design. That is also why Boeing tried to distance themselves from the A350, among others by trying to stretch the -9 a step ab...

And we have reports from our respected member Lightsaber that the GE9x engine is already better than spec after the first engine tests. So we'll have wait and see how the airlines will act. I heard the initial tests resulted in an engine failure, a significant redesign, and a high probability of no...

Re: Reuters: Airbus is studying A321XLR with extended range over LR

If we assume that, with reasonable limits, a meter of A320 fuselage adds about .5-.7t per meter, 2 meters combined with the 97t MTOW, such a minor stretch could help solve the fuel space / luggage capacity problem a bit. It could create the badly needed additional luggage / ACT cargo hold space. Th...

Southwest is organized very much around the 737, but they will not fly it for ever. The 737-7 is e.g. about 6t heavier than the A220-300. How much fuel is that per year, for say 300 aircraft?
