I don't think that makes sense. If you have extra thrust for the emergency, then your take-off and go-around calculations would allow for a shorter runway and better climb-out. There are flights where this would allow extra payload/range. Another consideration: If the 777X, for example, wanted its ...Jump to post

So only 22 or 23 quarters to go! Rate 14 started this quarter (2Q), so we should see ~14% earning acceleration from that alone. And the mix will continue to improve as 78X deliveries increase and as the few -8 deliveries incorporate the last round of commonality with -9's. If BA sees, say, $35mn/de...Jump to post
I'm gonna say it: best-looking airliner of all time. That's sarcasm, right? No!!!!

Thanks for that work @ Momo1435 . I've seen some of the operating numbers for the 787-10 versus its competition and it's a really astounding aircraft performing in line with the best of hype.

The link is dead. I've read analyst figures of $1.04bn in total deferred reduction (production and tooling), implying $30.7mn per frame. It's basically arbitrary whether Boeing apportions production profit to deferred production or tooling, so it's important to look at the total deferred delta inste...Jump to post
BA's calculation shows once again that the A380's lack of meaningful efficiency edge prevented it from selling better. For a 12 year lease, a $30-50mn Capex delta works out to annual payments equivalent to 4-8% of A380's annual fuel burn depending on fuel price and utilization. So a slightly better ...Jump to post
With a camera mounted outside the cockpit the pilots would be reality TV stars no more than the passengers and cargo - i.e. not at all.
Is there another hazard/catastrophe around the corner? If the MCAS patch corrects a tendency to pitch up towards stall in high-speed flight then don't we have an unstable aircraft? Is there a danger that, absent 2.5 degree stab authority, the MAX will go into high-speed stall while a cruise captain ...Jump to post
Maybe - hopefully IMO - this is a sign to Boeing to slow down and wait for Ultrafan or not do NMA at all.
"The last direct-drive turbofan ever launched" is a dubious project for 2025 EIS.
That, excuse my French, has bugger all to do with my point on the a380-800 wing being a lot lighter than the a380-900 wing would have been. And the wing-weight delta between -900 and -800 has bugger all to do with the point that the wing is too BIG - not that it's too HEAVY. That's why I said your ...Jump to post
The next VLA will most likely be a BWB. You need a step change in efficiency to make really large airframes attractive to airlines. The crucial question is whether there is a step-change in efficiency due to scale for BWB or any other form. What about the BWB form makes a VLA-BWB better than a 300-...Jump to post

Just because a fuselage stretch can be taken doesn't mean that the wing is overweight and overbuilt. The A389 wing would have needed strengthening to increase the MTOW towards 600 tons, this is common knowledge. Indeed - I have had to counter this idea that the A380-800 is flying on a much heavier ...Jump to post
The A380 uses 116inch diameter trents engines with around 80,000lb of thrust. An optimised A380-800 could have used the 112inch diameter trent engines that power the 787. The A380 could have then piggy backed on any PIPs that the 787 engines received. You're right about the cross section etc. - sou...Jump to post
We need to ship that professor one of the medals for predicting A380 failure from the start.

787MAX takes over the heart of the market in the A359 segment (787-10MAX). That IMHO would be a revamp comparable to the 777X. New legs, new Wing, new Engines ( do we really like the way the fuselage is done? ) That assumes a larger fan. With geared fans could you not get away with a smaller core a...Jump to post
The best of all, EK passengers will not have to contend with 9-abreast 787s that is even tighter than the 77W I’m pretty sure that is not true. Everything I see has EK 777’s at 17”. Most 787’s are slightly bigger than that. 777 cabin is 231in wide; 787 is 216in wide. That's 15in difference. Arithme...Jump to post
Do you think it's impractical to use an Ultrafan-like engine on the 777X, beyond the issue you raised above that you wouldn't expect such a beast to be competitive with the A350? Probably not impossible but might require higher landing gear. And as you say, a metal 777X can't compete against a plas...Jump to post
Is any current aircraft built to accommodate such large bypass ratios and fans though? If you're talking about Ultrafan BPR, I addressed that above: new "slim-line" nacelles mean that the on-wing engine shouldn't should be much larger, if any, than current engines. TXWB's nacelle diameter...Jump to post
The other option Boeing have is to cut the asking price for the 77X so much that they sell it for a substantial loss or at best break even on a recuring cash flow basis. But that is no viable option either. "Market intelligence", IIRC, says Boeing can build the 77W for less than $100mil r...Jump to post
I think we are making a ton of assumptions. The first is that the ultra fan will be ready by 2025, the second being that it will be significantly better than the engines on the 777X after a PIP or two. I'm not assuming 2025 but even a slight slippage means the 777X has only 6-7 years at the top. Re...Jump to post

Now, with the possibility of the A350Neo getting quite a bit better engines than the B777X from maybe as early as 2025 I cant see any new airline placing an order for the B777X with delivery after the time when an A350Neo would be available.

I think people in Seattle and Cincinnati may see this threat coming.

A350-2000 with Ultrafan engines will absolutely destroy the 777-9 and give Airbus the monopoly on the VLA market (insofar as such market makes any conceptual sense - it doesn't). Except this time the Airbus monopoly will be profitable, unlike with A380.Jump to post
A clean-sheet, double-decker VLA might be the best and last hope for the return of quad engine airliners. At some point, ETOPs and one-engine out/takeoff requirements may become so onerous for something with 450++t MTOW that it might be more cost-effective to go with something like 4 * 50k engines ...Jump to post

Ah, but Boeing can also stretch the 779 to a 777-10Max and the game continues. Only if Boeing wants to play the same game that Airbus played with the A380.
