i don't see the obsession with range. The plane will beat anything out there up to 5500, 6000nm, probably to the edge of its range envelope on fuel burn. This is the majority of routes in this class. The 330 was in this niche and sold exceptionally despite more "capable" 777s available at the same time.

There's more demand for what it can do than what it cannot. It's a 789 that swapped fuel for pax. Should inherit all of the other positive characteristics of the 789 in terms of operating efficiency. If it were bigger it would just be "on par" with the 359's economics. As things stand, it's nearly 10% better on burn. This is a differentiation that creates a product selling point.

What it does do is not go head-to-head with the 359, it brackets it. It's cost-wise dominant over the 359 through its operating range. If those are the routes you wanna do 330 pax with, it's the cheapest jet to do it with. If you want to fly further, you can choose the 789 out to about 7100nm with roughly 300pax or you could choose the 359 probably to 7500nm with the same load.

Look at it this way- NZ has the 789 and they're looking at ways to shed weight to get to JFK, not acquire a much bigger jet. The 787 series is in a position where the operating economics are compelling to airlines and all this talk of extra cargo over these long ranges...that's just not really where most of the market is. These are passenger airlines, not cargo carriers; cargo is a side business, gravy. If you're the sole operator on AKL-JFK, you can let DL carry the freight in its 77Ls lol as you command a nonstop premium on that route. To offset the .4t/hr burn differential, that's 800kg of fuel per hour over a ULH mission, you have to have consistent cargo demand and the shore-side capability to handle it (personnel, equipment, etc.).

I look at Boeing's WB strategy and I think they've got the right idea. Instead of wasting money going head to head, they're taking smaller risks to shrink the competitive monopoly the opposition's plane has in terms of payload and range, squeezing it into a niche. The 78J makes the 359 flatly noncompetitive economically on most routes airlines fly. For those the 78J cannot do, Boeing is offering the 777x and we will have to wait to see how it performs (the airlines appear to be doing the same if we look at recent orders).

Very clearly, Boeing made the 787 to carry passengers to distance as a primary focus. The 777x is the heavy hauler if you need it


A 10 % fuel burn advantage against a A350 is dreaming. Can you somewhere get a confirmation of those numbers?

The 787-10 has slightly more space than the A350-900, has perhaps a 5 to 10 t difference in OEW (4 to 7%) and there is no way, that there is a 10 % fuel burn advantage at a similar load. At 254 t MTOW for the 787-10 and 264 MTOW for the A350-900 (equal to 10 t difference in OEW) the weight difference between both frames would be about 4 %.
At 254 t MTOW for the 787 and an OEW difference of 5 t, the weight difference would be inside of 2 % for the same load.

The A350-900 has a bigger wingspan and slightly newer engines. It would be interesting how somebody gets the crazy idea about a 10% fuel burn delta.

I Would be factoring in the 787-10 having more seats. KLM will have 344 seats on the 787-10 with more premium seats than Air France in the A359 who has 324 seats. That is a 6% capacity difference. If OEW is 4-7% lower and capacity is 5-7% higher with the 787-10, I could see a 10% fuel burn per passenger being true.

x% lower OEW does not mean x% lower fuel burn! Any way OEW diffrence will be much narrower. diffrence between 787-9 and A350-900 is from 7-12 tons diffrence with 787-10 would be from 0 to 5 tons especialy with more seats and more premium seats the diffrence will be narrower. Of course more pax on same weight with less engine thrust will be more ecconomical but antil 787-10 run out of MTOW the A350-900 can add fuel or cargo. It always depends what is requirments.

At which point the A350 will probably also get new / updated engines.

The 787-10 and A350-900 have very similar numbers regarding seats. Two class 330 (32 J and 298 Y) for the 787 and 325 (48 J and 267 Y) for the A350-900, in this example you would I assume see a higher RASM for the A350-900. The 787 is 2 m longer, the A350-900 is wider. It would depend on the seat plan, what frame comes out above in seat numbers. Both frames have a 440 seat max pax.

You can not compare two set ups from different airlines most likely for different use. You will use a different seat plan for medium to long haul, compared to long haul to ultra long haul. French Bee does two class 411 on the A350-900 (35 W + 376 Y).

10 % full burn advantage brings you to a fantasy world of imagination, nothing else. Singapore is now taking its first A350-900 regional, clearly for a similar use as A787-10 would be used.

10% difference is in the same territory as the A346/77W disparity. It seems too large to me, we don't have exact numbers but I'm sure I've seen one of the CEOs of a big lessor say that the difference was not that much, which I take to mean 5% or less.

If they do increase the MTO of the 7810 they should make it optional, or make it the 787-11. The 7810 is the best choice for medium routes, which are the vast majority. An MTO increase will almost certainly entail an empty weight increase as well, and hence a reduction of efficiency for the shorter range version. Since all other widebodies seem to be seeking 8,000nm range when most routes do not need it it is good to have a choice that doesn’t.

It is more than the A340-600/777-300ER disparity, that was 8 %.

Wow, would Airbus prefer the 78X get a MTOW increase or not. It seems Boeing was quite happy doing the true stretch for the -10, optimizing at the exact MTOW of the -9. Yes it is range limited, but its range is still better than like 80% of all routes, many airlines do not have city pairs requiring more range than the -10. Yes, it lost a ton of range for lots more payload. It has differentiated itself from the pack, but half of the airlines it is not the best choice, the other half it is a real profit maker. If just 5% savings that is an extra $50 per ticket on a flight, either of which is enough to squeeze its competitors or add to the bottom line.

Same with the 797, it will need to have a range maybe 1,000 miles further than current NB's for it to have the economics that will make it sell. In other words, it needs to "Go Green" by saving lots of energy.

10 % full burn advantage brings you to a fantasy world of imagination, nothing else. Singapore is now taking its first A350-900 regional, clearly for a similar use as A787-10 would be used.


Minor point of correction. 48 + 267 = 315.

And we do have an airline with both and they are not similar in terms of seats. The 787-10 has 34 more seats for both with medium haul configs @ SQ.

A359: 40J + 263Y = 303 seats
78J: 36J + 301Y = 337 seats.

I do agree that there is no way in hell the 787-10 burns 10% less fuel than the 359.

However I do think the poster may have been referring to a per seat basis and this is easy to see, 34 is an 11% increase in seats.

i don't see the obsession with range. The plane will beat anything out there up to 5500, 6000nm, probably to the edge of its range envelope on fuel burn. This is the majority of routes in this class. The 330 was in this niche and sold exceptionally despite more "capable" 777s available at the same time.

There's more demand for what it can do than what it cannot. It's a 789 that swapped fuel for pax. Should inherit all of the other positive characteristics of the 789 in terms of operating efficiency. If it were bigger it would just be "on par" with the 359's economics. As things stand, it's nearly 10% better on burn. This is a differentiation that creates a product selling point.

What it does do is not go head-to-head with the 359, it brackets it. It's cost-wise dominant over the 359 through its operating range. If those are the routes you wanna do 330 pax with, it's the cheapest jet to do it with. If you want to fly further, you can choose the 789 out to about 7100nm with roughly 300pax or you could choose the 359 probably to 7500nm with the same load.

Look at it this way- NZ has the 789 and they're looking at ways to shed weight to get to JFK, not acquire a much bigger jet. The 787 series is in a position where the operating economics are compelling to airlines and all this talk of extra cargo over these long ranges...that's just not really where most of the market is. These are passenger airlines, not cargo carriers; cargo is a side business, gravy. If you're the sole operator on AKL-JFK, you can let DL carry the freight in its 77Ls lol as you command a nonstop premium on that route. To offset the .4t/hr burn differential, that's 800kg of fuel per hour over a ULH mission, you have to have consistent cargo demand and the shore-side capability to handle it (personnel, equipment, etc.).

I look at Boeing's WB strategy and I think they've got the right idea. Instead of wasting money going head to head, they're taking smaller risks to shrink the competitive monopoly the opposition's plane has in terms of payload and range, squeezing it into a niche. The 78J makes the 359 flatly noncompetitive economically on most routes airlines fly. For those the 78J cannot do, Boeing is offering the 777x and we will have to wait to see how it performs (the airlines appear to be doing the same if we look at recent orders).

Very clearly, Boeing made the 787 to carry passengers to distance as a primary focus. The 777x is the heavy hauler if you need it


A 10 % fuel burn advantage against a A350 is dreaming. Can you somewhere get a confirmation of those numbers?

The 787-10 has slightly more space than the A350-900, has perhaps a 5 to 10 t difference in OEW (4 to 7%) and there is no way, that there is a 10 % fuel burn advantage at a similar load. At 254 t MTOW for the 787-10 and 264 MTOW for the A350-900 (equal to 10 t difference in OEW) the weight difference between both frames would be about 4 %.
At 254 t MTOW for the 787 and an OEW difference of 5 t, the weight difference would be inside of 2 % for the same load.

The A350-900 has a bigger wingspan and slightly newer engines. It would be interesting how somebody gets the crazy idea about a 10% fuel burn delta.


Boeing said around 8% on seat mile, 4% lower trip fuel. Other analysis is around 7%/4.5%. Udvar-Hazy concurs. 10% is slightly too high, sorry. Boeing had originally claimed that number, against what configuration of each jet I'm not sure.

you could really just search up 787-10 vs 359 and like let the search engines do the work

Seeking Alpha estimates per seat mile $0.042 in fuel for the A359 and $0.039

https://seekingalpha.com/article/276908 ... 0minus-900

Basically, within 4,000nm (still air), the 787-10 is far more economical. From 4,000nm to 5,000 nm, cargo will determine the choice. (More cargo=A359 for revenue, less cargo=787-10 to reduce costs). For long range missions, the A359 will dominate. It was 2.6 tons more engine to help lift the extra fuel. Until you get past 4,500nm, the extra engine weight is a cost. Afterwards, an efficiency advantage. Same with the wing unless the better shortfield of the A359 is required (ET). I see many mixed fleets.

The 787-10 needs weight loss (more fuel) and CMC turbine components (hand me down from GE9x).

The SA article shows the 78J with a 8%-7% seatmile fuel burn advantage across its entire range envelope, from 2000nm (8) to 6000nm (7).
The advantage to the 78J won't decrease with cargo- weight is weight and the competing jet will be carrying the same additional load. the 78J won't be able to fly the fuel load necessary to reach those ranges when swapped for cargo (the 78J is already effectively a 789 that swapped fuel for pax). But for a payload-on-payload comparison, it has a significant advantage across the entire mission profile.

For long range missions, between these two, the 359 is the only one of them that can actually perform them. But at the same time, the 789 can be configured to carry nearly the same pax as the 359 at substantially better economics almost as far as the longest-range 359 variant can fly. At 250 for 789 and 315ish for 359, i expect almost equivalent range as the brochure ranges for 350 are overstated still. After that 7600nm cliff, it's either you lighten your config as QF did and NZ appears to be intending to do or else you procure the 778. SQ is flying 70pax light of brochure on LAX-SIN in their 359. that's basically the same as UA carries on their same city pair but UA has a nearly 8% fuel burn advantage...pax-on-pax this is the difference between the two families. I know you're not doing it at all but some would be better to just accept these facts.

As for more range, the 78J needs better engines and to get lighter for that but I don't think BA's strategy is to try to go head-to-head with the 359, involving the serious redesigns necessary. There's no competitive advantage in doing so. Let the 359 have its little, shrinking niche. If the sales since deliveries began of the 359 are any measure of success, they're on the right track with their strategy.

I cannot emphasize this enough- since the 359 *actually* got delivered to commercial service, it has 82 net orders. In five years. This is incredibly troubling for that manufacturer. Their brandest newest effectively flagship jet (the 380 is dead) has been outsold handily by their own warmed over stopgap 330NEO. I know people here are massive fans of this plane but the market hasn't been since it went into service.

So why would Boeing copy something they're beating 4.5:1 over the past half-decade? The question here should be the converse, the A350 needs to change to compete with the 787 not the other way around.

That's a pretty meaningless stat.

There's a backlog of 659 A350's and 781 787's. At the current rate of production, Airbus has about a 6-7 year backlog and Boeing has a 5-6 year backlog.

Neither one is in any immediate danger.

yeah you're right, 5 years' worth of sales data since the 359 started deliveries is "meaningless"

I wonder what would be considered meaningful...seeing as the backlog is totally irrelevant to forward sales.

It is not when Airbus discussed going to rate 13 on the A350 and as far as can be determined that isn’t going to happen. Presumably builders know more than the current backlog numbers when they make these decisions. If everything is good why not go to rate 13 as they stated from the beginning?

How much better on fuel will the engines be when the CMC components are fully implemented and when do you expect this?

It's not irrelevant at all. Slot availability is one. If you can't receive orders for 3-5 years anyways, airlines might be holding off, especially with the potential of a large economy downturn in the next few years.

There's also the concept of a total market, and with over 2200 planes ordered (between the A350 and 787), we might be reaching the point where there aren't many orders left to sell, until some of the newer fleets need replacement. Some of it could be cost and size too. Looks like there were around 30 orders for the 788 last year, something Airbus can't compete with.

The 78J has the same advantage over the A359 as the A359 has over the 77E - smaller engines. That is why the A359 with engines about 7% SFC better than say, RR Trent 892s, has more than 15% less fuel burn.
The Trent 1000 - TEN is newer than the Trent XWB as the 1000 - TEN is a direct shrink of the XWB. The only difference between the two is the XWB gains 2% from a larger fan, and loses about 13% due to the 10000 lb thrust difference.

Some of it could be cost and size too. Looks like there were around 30 orders for the 788 last year, something Airbus can't compete with.

Near term slots are required to sell a block. That is why Boeing increased 787 production. The #1 problem with the A350 is the first available slot is years out. In a way, if EY cancels their A350 order, it would allow more additional sales.

Now, why hasn't Airbus announced a production surge? It is past due to help sales. The lack of near term production slots hurt the 787 in early production (benefit A330CEO). The same is happening to the A350 now.

Boeing is taking a risk on white tails. Just as Airbus did on the A300. In the past, both have taken the risk, but didn't realize any downside as customers paid premiums for extra near term deliveries. e.g. A330CEO and 77W until it was obvious to take no more risk.

Roles could change overtime with improvements. Take A333 as an example: it was never thought to be an 777 competitor, but with multiple MTOW increases, it basically kills 77E.

Airbus have acknowledged the difference was around 12%. *shrug*

As for 787 / A350 fuel burn, chaostheory has posted that on a 3000nm stage length, the difference between a 787-9 and A350-900 is about 5% (around 300kg an hour) with the 787-10 being effectively the same. And the A350 has been PiP'd since then, so that difference will be even less now.

So a 10% reduction is, as some have noted, ridiculous.

10% isn't the answer. Please see my attached resume post and link. There is a 7% to 8% difference unless you compare only at the extreamely range if the 787-10.

The difference is based on mission length. No difference is just not plausible either. You would have zero 787-10 sales if that was true. If the 789 only saved 5% in fuel burn, in no way would Boeing be increasing production.

To 5000nm, a big advantage to the 787-10. But soon thereafter, the advantage goes to the A359.

So LH to Asia or US West coast should be A359.
But BA TATL or to India should be 787-10.

Orders so far have been rational. Both should keep selling.

It amazes me how people here do not do mission analysis. I've participated in sales campains where every line planned to be opperated was modeled, over seasons, and weighted. Two airlines could be given the same sales offer and one would chose A to save money and the other B due to different mission profiles.

As for 787 / A350 fuel burn, chaostheory has posted that on a 3000nm stage length, the difference between a 787-9 and A350-900 is about 5% (around 300kg an hour) with the 787-10 being effectively the same. And the A350 has been PiP'd since then, so that difference will be even less now.

So a 10% reduction is, as some have noted, ridiculous.


Trav corrected himself and said it's probably more like a 4% reduction in fuel burn and 8% reduction in seat-mile fuel burn. The 78X is slightly longer so it should carry more when both are in 9-abreast. And Boeing has capped the top end with the 778 and 779, squeezing A359 in the middle. If Boeing can render every Airbus widebody other than the A359 irrelevant, it's already a victory. Airbus could do the same on the narrowbody front by rendering every Boeing other than the 738 irrelevant.

The 787-10 has slightly more space than the A350-900, has perhaps a 5 to 10 t difference in OEW (4 to 7%) and there is no way, that there is a 10 % fuel burn advantage at a similar load. At 254 t MTOW for the 787-10 and 264 MTOW for the A350-900 (equal to 10 t difference in OEW) the weight difference between both frames would be about 4 %.
At 254 t MTOW for the 787 and an OEW difference of 5 t, the weight difference would be inside of 2 % for the same load.

The A350-900 has a bigger wingspan and slightly newer engines. It would be interesting how somebody gets the crazy idea about a 10% fuel burn delta.


I Would be factoring in the 787-10 having more seats. KLM will have 344 seats on the 787-10 with more premium seats than Air France in the A359 who has 324 seats. That is a 6% capacity difference. If OEW is 4-7% lower and capacity is 5-7% higher with the 787-10, I could see a 10% fuel burn per passenger being true.


The 787-10 and A350-900 have very similar numbers regarding seats. Two class 330 (32 J and 298 Y) for the 787 and 325 (48 J and 267 Y) for the A350-900, in this example you would I assume see a higher RASM for the A350-900. The 787 is 2 m longer, the A350-900 is wider. It would depend on the seat plan, what frame comes out above in seat numbers. Both frames have a 440 seat max pax.

You can not compare two set ups from different airlines most likely for different use. You will use a different seat plan for medium to long haul, compared to long haul to ultra long haul. French Bee does two class 411 on the A350-900 (35 W + 376 Y).

10 % full burn advantage brings you to a fantasy world of imagination, nothing else. Singapore is now taking its first A350-900 regional, clearly for a similar use as A787-10 would be used.


No the 787-10 and A350-900 do not have very similar seatcounts. Airbus uses old fashion recliner seats with 60 inch pitch in their marketing seatcount. Boeing updated seat maps and now use lie flat seats for business class. If you want to be accurate, you can’t compare Airbus and Boeing seatcount marketing numbers like you did. I used Air France and KLM for comparison since they have similar seats. Another user compared Singapore. In the real world the 787-10 has more seats than an A350 which is how we get different fuel burn per seat figures. I don’t know if it is 6, 8, 10 or 12% different per seat, but seat counts vary so you can’t assume the two planes have the same number of seats.

Why would anyone buy the A359 if the difference was that much? When the difference is that much one product is effectively driven out of the market, but this isn't the case at all with the A359, and 78X orders haven't really taken off yet, at the moment I would say it was 'respectable' but not much more.

There is increased network flexibility for medium, long and ultra long haul route operations with the 359 thanks to better payload/range figures than the 78X. Whilst the 78X is largely limited to perhaps 10 hour routes with cargo realistically and excels at that, the trip cost difference should be marginal at similar pax/cargo LF.

The 359 will definitely suit a wide range of airline's networks better than a 78X/789 combo would when you look @ the leg lengths, average pax carried per leg, direct/indirect operating costs etc.... and vice versa, the decision is going to be very airline specific.

The A346 was a very large aircraft and as such if you didn't fill it with passengers there was a multiplier effect on the 10% fuel efficiency deficit.

Not only is the A350 a smaller aircraft, it is a couple of generations younger. As such in monetary terms a 10% fuel efficiency deficit would not equate to the cost disadvantage of the A346 over the 77W.

For argument sake if a 787-10 operator wanted to fly the aircraft on routes longer than its marketed maximum range with a full payload they would have to reduce the amount of payload. If we consider a paying passenger is weighted at 110kgs and the 787-10 burns ~8000kgs of fuel per hour to fly 1000 klm's, a 787-10 flying a A350 mission profile could have 20% higher CASM costs.

On the flip side if reduced OEW weight and upgrades to engines extends the operating range by 500-750 klm's, the window / crossover where the A350 is the more efficient aircraft also reduces.

If we consider SQ use their 787-10's and A350's on similar stage lengths, but in different markets we can partly come to an understanding that these aircraft have strengths and weaknesses that go beyond base operating economics.

IMO the reason we have not yet seen an ER 787-10 is because Boeing currently does not have to.
They are producing as many 787 at a new higher rate as they can. Ifsales and sales prospects indicate a substantial rate reduction you may see it.
Any tech advancement will almost certainly be available to both 350 and 787, so the answer lies in the conceptual basis of both aircraft, and here the 787 wins, coming from below, whilst the 350 misses out because it cannot realistically go to 10 abreast for the major market, the XWB makes it heavier than it needs to be, and powerful engines are required to achieve payload range,

An ER version would come with extra structures which would need to be balanced against the opportunity that such an aircraft would bring.

For instance an 787-10ER may have an additional 8 tonne of structures. If this is the case the application of new engine technology would have to be significant enough that it could carry the additional mass whilst at the same time reducing operating costs by a margin that is economically viable. I can't see this happening anytime in the near future.

In comparison a lighter 787-10 with more efficient engines would not only have more revenue opportunity (higher payload) it would also cover a higher percentage of the the overall market (i.e. routes up to 5500nm instead of 5000nm).

If I remember correctly Boeing originally proposed the 787-9 and 10 to have a larger wing. I am not too sure if that wing would still be feasible and how much of a gain the 787-10 from using it.

I suppose time will ultimately tell. At my age I am willing to wait!

you could really just search up 787-10 vs 359 and like let the search engines do the work

Seeking Alpha estimates per seat mile $0.042 in fuel for the A359 and $0.039

https://seekingalpha.com/article/276908 ... 0minus-900

Basically, within 4,000nm (still air), the 787-10 is far more economical. From 4,000nm to 5,000 nm, cargo will determine the choice. (More cargo=A359 for revenue, less cargo=787-10 to reduce costs). For long range missions, the A359 will dominate. It was 2.6 tons more engine to help lift the extra fuel. Until you get past 4,500nm, the extra engine weight is a cost. Afterwards, an efficiency advantage. Same with the wing unless the better shortfield of the A359 is required (ET). I see many mixed fleets.

The 787-10 needs weight loss (more fuel) and CMC turbine components (hand me down from GE9x).

Lightsaber


The SA article shows the 78J with a 8%-7% seatmile fuel burn advantage across its entire range envelope, from 2000nm (8) to 6000nm (7).
The advantage to the 78J won't decrease with cargo- weight is weight and the competing jet will be carrying the same additional load. the 78J won't be able to fly the fuel load necessary to reach those ranges when swapped for cargo (the 78J is already effectively a 789 that swapped fuel for pax). But for a payload-on-payload comparison, it has a significant advantage across the entire mission profile.

For long range missions, between these two, the 359 is the only one of them that can actually perform them. But at the same time, the 789 can be configured to carry nearly the same pax as the 359 at substantially better economics almost as far as the longest-range 359 variant can fly. At 250 for 789 and 315ish for 359, i expect almost equivalent range as the brochure ranges for 350 are overstated still. After that 7600nm cliff, it's either you lighten your config as QF did and NZ appears to be intending to do or else you procure the 778. SQ is flying 70pax light of brochure on LAX-SIN in their 359. that's basically the same as UA carries on their same city pair but UA has a nearly 8% fuel burn advantage...pax-on-pax this is the difference between the two families. I know you're not doing it at all but some would be better to just accept these facts.

As for more range, the 78J needs better engines and to get lighter for that but I don't think BA's strategy is to try to go head-to-head with the 359, involving the serious redesigns necessary. There's no competitive advantage in doing so. Let the 359 have its little, shrinking niche. If the sales since deliveries began of the 359 are any measure of success, they're on the right track with their strategy.

I cannot emphasize this enough- since the 359 *actually* got delivered to commercial service, it has 82 net orders. In five years. This is incredibly troubling for that manufacturer. Their brandest newest effectively flagship jet (the 380 is dead) has been outsold handily by their own warmed over stopgap 330NEO. I know people here are massive fans of this plane but the market hasn't been since it went into service.

So why would Boeing copy something they're beating 4.5:1 over the past half-decade? The question here should be the converse, the A350 needs to change to compete with the 787 not the other way around.




169 787-10 sold compare to 724 A350-900. outstanding:-)


787-10 cannot fly 6000nm with reasonable payload! At MZFW (192776kgs) can fly according to ACAP to approx 4200nm compare to A350-900 basic vw00 model(268t MTOW) MZFW (192000kgs) 5700nm. For 6000nm is max MZFW for 78-10 172000kgs and A350-900 at MZFW 190000kgs. Of course that are theoretical numbers but I have no better sources. In real world the range will be reduced for sure for both models.


I don not thing A350 range is oversatated but you have to campare same config densit on same route at same enviroment. 787-9 can do lot of ULH routes as A350-900/1000 but is the payload comparable?

I think there is an opportunity for Boeing, in between the 787-9 and 777-8.

300-350 seats up to 8000NM. The middle of the long haul market, Asia. The former (sales) 777-200ER/-300ER territory; huge.

The 787-9, 787-10 and 777-8 in there, are what they are. Smallish the -9, restrained the 10, heavy the 777-8.

Boeing will deny until they have a solution, probably some form of 787-10ERX. I expect them testing the water this year. It needs bigger engines too.

The hard thing to know is what is the limiting factor on taking it above 254T. I remember someone mentioning that the wing is good for 280T but the limiting factor was the gear.

Airbus seems to be able to magically increase MTOW all the time without significantly changing structures. How much is left in the Base 787-10 without major changes?

If (and that's a big if) it's just he gear - is there any extra room in the gear bays for a bigger gear?

Alternatively - are there aero cleanups to be done still? Different Wingtips? Different Body fairings? Lighter interior?

Would they be better off to focus on lowering weight and cleaning up Aero and adopting CMC's in the engines ( basically PIP's) to get more out of it?

3D printing could take a lot out of the interior. Didn't they go away from some lighter titanium structures that were already in use for cost reasons?

So adding it up - Maybe 2-3% from Aero (Assuming new wingtips) - 2-3% from the Engines (CMC's) and do what they can to take weight out of it (3-5,000lb?) - does that get them where the plane is more attractive for a lot more people without resorting to MTOW Increases and get's them close to 5,000NM at MZFW?

What was said was the bigger wing did not earn its keep. The extra lift was negated by the extra weight and the extra manufacturing complexity. One thing helping the 787 family is lower weights. Since they and their competitor are using the same generation engines (in particular T1000-TEN and TXWB are the same tech) the lower weight is significant.

Maybe things have changed in the decade since the decision was made, but maybe not enough to matter. Significantly, Boeing has used the 787 wing tech to create the new 777x wing and presumably will be doing another iteration with 797/NMA so by the time those projects are done they may go back and address the 787 family. A complicating factor may be that the 787 wings are manufactured largely by the Japanese heavies who may or may not want to invest more in the product.

The 787-10 is exactly how it was designed. A simple stretch of the 787-9, exchanging fuel for passenger.

The A350-900 was designed to be what it is. A similar sized frame like the 787-10, but with similar capabilities as the 787-9.

That means that the A350-900 comes out slightly heavier. Bigger wings to carry more weight, a bigger MLG to carry more weight, slightly more structure to carry more weight and so on. If the 7878-10 would have been designed for the same capabilities as the A350-900, it would be a frame of similar OEW.

If Airbus would like to make a frame with capabilities similar to the 787-10, but bigger in capacity, they could stretch the A350-900 without increasing MTOW.

In the moment the A350-900 wins the race regarding sales.

That's were Boeing is probably going to end up. A wing to boost payload range into what most legacy's want; fly a full load from Asia into Europe / US. Looking at your time table, that might be end next decade, which seems far out. Maybe Japan remains a good option.

Cargo is weight that brings revenue, and this revenue exceeded the fuel penalty you have to pay in order to carry it.

You are really making the wrong cause-effect relationship here, as we as making a few unfair comparisons:

- SQ configuring its A359 with 253 seats does not mean that the plane cannot carry more on the routes it intends to fly. We have seen how its 276t MTOW variant on SIN-SFO was still 8t below MTOW while being full (we don't even know the weight of cargo). In terms of aircraft capabilities, the plane could've carried 80 more passengers in that variant only. However, their decision to configure the aircraft premium heavy simply didn't allow that. They ran out of space to add more seats.

- assuming that UA's 789 is simply more profitable than SQ's A359 based on the seating density in two random airlines is simply an unfair comparison. you know that that if SQ configured its imaginary 789 in the same seating density, it wouldn't seat more than 225-230 pax, and even with that it wouldn't carry as much cargo as A359 could. 789 might burn 5-8% less fuel per hour than the earlier versions of A359 (depending on payload), but A359 has an area that's 10% larger while carrying more payload/cargo. CASM is lower with A359, and hence it should be more profitable if both planes took off at MTOW.

- PR flies its A359 on MNL-JFK (which is longer than SIN-SFO) with a 295 seating configuration, so? I thought the 253 seat count at SQ was the threshold of A359's capabilities. That's why it's better to discuss in terms of payload.

- We saw in the technical forum how DL flew its PEK-DTW while carrying 238 pax with a TOW of 238. you might argue that a 789 would've done better. But the other 25 tons of cargo it carried on board is just too much for 789 to even take off with. To put things in perspective, that cargo weight is close to the difference in weight between 77E and 77W. This cargo brought DL more revenue than a 789 would have done on the same flight.

If the sales since deliveries began of the 359 are any measure of success, they're on the right track with their strategy.

I cannot emphasize this enough- since the 359 *actually* got delivered to commercial service, it has 82 net orders. In five years. This is incredibly troubling for that manufacturer. Their brandest newest effectively flagship jet (the 380 is dead) has been outsold handily by their own warmed over stopgap 330NEO. I know people here are massive fans of this plane but the market hasn't been since it went into service.



I see that you are cherry picking the order count here. 787 got -62 (that's negative) order in the 4 years after its first flight. Was that troubling for Boeing? Orders come in cycles. As others have said, Airbus would be crazy to feel anxious about orders of a plane that has exactly 6 years of backlog.

So why would Boeing copy something they're beating 4.5:1 over the past half-decade?


And in the half-decade after 787's first flight, A350 outsold 787 by a ratio of 3.5:1.

See, those figures are just meaningless.

If I remember correctly Boeing originally proposed the 787-9 and 10 to have a larger wing. I am not too sure if that wing would still be feasible and how much of a gain the 787-10 from using it.

What was said was the bigger wing did not earn its keep. The extra lift was negated by the extra weight and the extra manufacturing complexity. One thing helping the 787 family is lower weights. Since they and their competitor are using the same generation engines (in particular T1000-TEN and TXWB are the same tech) the lower weight is significant.

Maybe things have changed in the decade since the decision was made, but maybe not enough to matter. Significantly, Boeing has used the 787 wing tech to create the new 777x wing and presumably will be doing another iteration with 797/NMA so by the time those projects are done they may go back and address the 787 family. A complicating factor may be that the 787 wings are manufactured largely by the Japanese heavies who may or may not want to invest more in the product.


That's were Boeing is probably going to end up. A wing to boost payload range into what most legacy's want; fly a full load from Asia into Europe / US. Looking at your time table, that might be end next decade, which seems far out. Maybe Japan remains a good option.

What legacies exactly are asking for a longer range 78X? This is Anet fantasy. Airlines are spoilt for choice on aircraft capable of those distances from the 788 all the way up to the 388.

I really do not understand the logic in thinking the 78X needs longer legs. The 789 and 359 do exactly those missions very efficiently.

The legacy's didn't ask for a bigger longer range 78X. Now they are replacing their 777s with A350 now. BA, AF, JAL, United, Cathay, Delta, Qatar, Singapore, must I go on? LH once called a spade a spade:

"The carrier decided not to order the 787 for a variety of reasons. “The 787-9 is too small for our requirements and the 787-10 does not have the necessary range for around 40% of the destinations,” says Carsten Spohr, CEO of the passenger airline division."

A 787 MTOW bump of 20-30t would do the job, but probably require significant modifications and use a newer engine.

You've still not answered my question though? Which airlines have asked for a longer legged 78X?

For LH, let's not rewrite history shall we? There were looking for A343 replacements, the 78X is a medium haul AC not designed for that market and the 789 was too small as I imagine they needed growth as the AC will be there for a few years.

However they ordered the 359 which as I mentioned does the job as well as the 789 and airlines will order the AC which is most suitable to their network needs. For LH this was the A359. When they need A330 replacements, they will again review and choose what works best for them.

One aircraft cannot be everything. There is a large market for medium haul widebodies and the 78X is best placed to capture that market from a unit cost efficiency POV.

PS I don't remember BA or AF quite replacing 777's yet, nor DL or QR for that matter.

LH needs to upgauge and carry more cargo to Asia. They have need. TPAC will too.

Not every aircraft can be everything. The engines alone on the A350 weigh 2.6 tons more. Their added efficiency pays off after 5,000nm.

Out to 5,000 nm (10 hours or so), the 787-10 is incredibly evonomical. Above that, not so much. The A350 is incredibly efficient on 12+ hour missions. They each have their niche.

The 787 needs a weight loss PIP and an engine PIP for some added range.

The A359 also has superior hot/high (ET).
We'll see on the orders. Some will come down to manufacturing cost which Boeing finally has under good control. 3D printed parts are expected to reduce costs about $3 million usd per 787 and the ramp up in production should cut costs another $2 million per airframe. This should allow impressive margins as well as some discounting.

We'll debate this for a decade+. Both will sell well.

It wouldn’t just need a new engine, it would need a new engine with a higher thrust as well.

Airbus should be cheering that Boeing won't change the 78X, as it is totally a deficient airplane. Look at all the A359 orders that Airbus will get because of this.

Boeing with the 789 took out all of the excess margin the initial design of the 788 had. The detailed design and test data allowed this. The original 789 specs was to keep the same MTOW as the 788, but there was a huge amount of cleanup to do of the design. The result is the 789 has little left over reserve. Doing the -10 as a true stretch did not push this, but it made a very efficient plane up until the range payload curve drops. It is not for all routes, but it is excellent for its select routes.

The 78X is the type of plane many airlines want to see the actual in service results. planes seem to have a +-3% variance between predicted results and actual. Those that perform better than predicted - the A321 currently, the A330 back at its inception, the 789 and the 77W all perform better than predicted. As is common the A332 & 328, the 77L & 778 that have nearly all the successful siblings attributes except being a shrink have not done well in comparison. The 77L has like 10% of the deliveries of the 77W.

The home team is Boeing, but as assets are apportioned among the various 797s(?), 787s, 777Xs is it wise to spend billions to duplicate the 350 nine? From my reading here on line the best strategy seems to be to reduce the large niche in which it is superior. Neither Boeing nor Airbus can afford to build the best plane in every particular niche. The 321 is awesome, but Boeing is not going to work at duplicating it. Again they are going to work at reducing the size of the niche in which it excels. The bitter, and pointless, discussion over Airbus's current strategy in improving manufacturing costs and efficiencies was pointless, because of course Airbus needs to do it, and in fact will do it very well (it just takes more time and money that manufacturers like). Airbus is going to improve the competitive landscape for everyone of its planes. Sales which lack now will appear.

They AREN'T MEANINGLESS at all!

The reason for this sales advantage during that time period is obvious- the 787 had SERIOUS problems with exploding batteries and other production issues! So manufacturers RATIONALLY saw a problem or potential one with a particular jet and they cancelled the heck out of orders in response! they didn't want to rush into a jet that ended up repeatedly grounded so frequently it was being called the NightmareLiner.

Nobody here, regardless of whether they're smeared as a "boeing fan boy," would seriously contest this. Once the 787 worked out its operational issues, the plane has been a resounding sales success.

The A350 hasn't. Sure, all the fans of this manufacturer that we find in abundance here are "certain" that the plane will be a huge success and sell a bazillion copies...but I don't believe that will be the case. As the bigger jets roll off service, the replacements aren't going to be bigger or even same-sized ones.

It's hilarious how the same people who say the 779 and 778 are too big and have no future think that the 787 is too small. When making one comparison, payload and range matter...oh wait, the 778 hauls more further? Well then it's trip fuel burn that matters. The 779 only sold to a couple airlines? EK? Well that's awful, what a joke! The 388 sold only to the same airlines? This is just a jet that's "before its time."

Please, stick to the facts and the market data. In this situation, the 787 does not need to change; it is the unquestioned market leader in widebodies right now and its manufacturer's strategic decisions (but not execution) has been spectacular. Airbus has ONE model only that they can sell to anyone, the 359 and its sales have lately (5 years) been anemic. It's been outsold by its older, smaller brother the 330Neo. Maybe the lack of bribes going forward has something to do with it or maybe the airlines actually aren't that enamored of the thing compared to what they could have gotten from the other mfr.

Most of them are also replacing 777s with 787s, as well. Heck, some of them even have the temerity to plan to replace 777s with 777Xs! :wideeyed:

Lies, damned lies and statistics. You can prove anything you want by using statistics if you use the parameters that suit your argument. It may just be that the A350 is mediocre and will not have many more sales. The line should then be expected to close in 2025-27 when the current backlog is reached and very few sales are recorded from here on in. I think that is the argument being made right now.

The sales success of the 787-9 is pretty much the biggest reason why the 787-10 hasn't been the sales success like some people predicted. The available production slots were simply sold to airlines buying the 787-9. This wouldn't have changed too much if Boeing had turned the 787-10 into a 787-10ER straight away. The current version is the budget version, designed to be very similar to the 787-9 in order to keep the development and production costs low after Boeing burned a lot of money on the 787 program.

Placing the 787-10 in a segment which is more similar to the A333 then the 77E cannot be considered as a bad move. It will be a larger replacement market when the bulk of A333s, which has been a very successful plane for Airbus, will start to be retired then the replacement market of all the 777-200 versions.

Boeing might have expected that the A350-1000 would have been popular, which would have resulted in less delivery slots for the A350 in the A359/787-10 segment. But as the 787-9 keeps on selling it's not a problem. The time of the 787-10 will come together with the time of the A3510. It will be interesting to see if Airbus is going to raise the production rate as this progresses. For now we will see more 787 orders then A350 orders simply because Boeing will start to produce 4 more 787's per month then Airbus produces A350s.

When it's time to put new engines underneath the 787 wings it will be time for Boeing to decide if they are also going to something more with the 787-10 then just the new engines. The market will ultimately decide what Boeing will do.

We better warn BA, JAL, Virgin, AF and SAS ASAP then, they´re getting their first A350 this year :wideeyed:
