There are simply not many routes in the world where you can fill 800+ seats consistently. actual sitting from ~450 to 600 with flatbeds, bar and more and more. we all talking about the same thing, i just ask not to use completely wrong arguments can planet live without a380 now? yes but she have a ...Jump to post
Ok, let's use 436 vs 845. Even with twice airport/navi charges, A333/787 will be more profitable. . yes. if you transport sardines only. and even here for 333 better comparing with 8-abreast actualy. a380 have much more room for unique leisure options comparing with any current plane. so its more c...Jump to post
compare apples to apples please.
with 436 actual sardines in 333 will be about 845 in 388, still having more room for each.

also, Volaris grounded 4 of 11 A319, and Aeromexico Connect - all 19 E135/145 it all about market demand. about grounded ssj: XA-JLG - substantially damaged barrel XA-PBA - nose damage, grounded since 2015 the rest is XA-BVM XA-JLV and i think can be used when they will be needed also about "In...Jump to post

We're talking probably 30-40 % higher OEW here. Two: Once you have the structure, you'll land probably 60-70% more passenger. Assuming standard 300 widebody, you raise it with 200 persons.

F1 teams try to get leaner overall burn out of their engines by having a locally rich small pre-ignition chamber which shoots out flames to ignite the main (lean) ignition chamber. Modern turbofans have rather similar combustion chamber AFRs to high performance piston engines so this tech could wor...Jump to post

what about higher temperature?
is it better for hydrocarbon only or for metane and hydrogen too?

Weren't they 4 wheel bogies with a double tire on each?
Think they were designed like that to be thin enough to retract edge on into the nacelles.
Is each tire an independent unit with individual rim and bearing or is it a "unit piece made out of rim and spacer segments fitted with two tires each. to check: can you independently rotate the tires on one axle stub? I would think that they rotate independently. It would affect the aircraft'...Jump to post
not sure i'm in right topic... what airbus need to do is admit they are now wrong in choosing fuselage size for widebodies. A350 is a perfect big wing with 787 fuselage 330NEO is a 787 size plane (for now, not about 1990) with less capacity. what they have to do is a change a cross-section. Can they...Jump to post

The IAE SuperFan would have been less powerful than the CFM56-5C series. IAE projected that the SuperFan would have delivered between 28000 lbf and 32000 lbf, compared to the 31200 lbf to 34000 lbf for the CFM. The biggest hit was fuel efficiency, not power. SuperFanned A340 must be an A330 class M...Jump to post

Any idea why the MS21-300 uses the PW1400G engine instead of the PD-14? PD-14 will be ready to fly in late summer. Why do not use already flying engine for test craft?

less engine hours (in trade for more start cycles for aux), light and simple aux engine with less fuel efficiency, but less dead weight, and may be beter fuel efficiency (1 *100%trust on cruise versus 2*(50-60)%)Jump to post
future aircraft will be with 1 cruise engine (unducted contra-prop may be), + 1 take-off engine (common turbofan), powering on take-off, landing and etops option only.Jump to post
I hope this is not "too old" topic.
