I think the A350-1000 has also the reason why it's selling less than the -900, poor timing to replace the 777-300ER, which is obviously not that old. It only replaced the similar-sized Quad-Engined A340-600, which has a reputation for being SUCH a GAS GUZZLER for having 4 engines, and only a HANDFUL of airlines operated the -600, and replaced it with the -1000. And some airlines that also had the aging Non-ER 777-300s also replaced them with the -1000.
I wouldn't agree about the non-ER for now. CX still holds on their -300s, Thai didn't get -1000s, neither did SQ, Korean, ANA. JAL ordered A35Ks to replace 300ER's. Correct me if I'm wrong
Small correction at 5:59 , low humidity is actually a desirable factor to generate thrust. Also these carriers are all based at sea level which helps a lot with performance (the air is a lot denser). But overall you’re right, hot summer take offs in the UAE at MTOW can be close to the limits
Yes, and no. Humidity can both be beneficial and detrimental. As water is not compressable, ingested into the main air stream, it can produce more thrust because of how much water expands when it turns into steam. Higher pressure in the turbine section creates more thrust. Before high bypass engines were a thing, some airplanes literally had water tanks on board, that would inject water into the engine to produce more thrust during take off. B707 was one. A modern engine produces more thrust on a rainy day than on a sunny day. It's not a massive amount, but measurable and noticable.
Even so, longer runways help a bit. The problem is not a given type of plane being unable to take off. Rather, than in so doing the engines have to be used at full throttle, and that means more rpms and at higher engine heat, which increases maintenance costs and decreases engine life. Actually Emirates chose (before changing their mind) 787-10s, which have substantially poorer field performance.
It worth noting that a lot of these middle eastern aircraft will also be aiming to link their hubs with smaller European airports. High performance will allow for more routes to be created.
@@CerberusTenshi Humidity represents water as a vapour. ie. a gas. Consisting of 2 hydrogen molecules (top left corner of periodic table) plus 1 molecule oxygen, it’s lighter and less dense than the largely nitrogen/ oxygen air. Less density equals less performance. We operated the B747SP with water meth injection. This was injected as a liquid, which is different to humidity. This lowered the EGT (exhaust gas temperatures), thus allowing for more fuel to be added till EGT limits were reached once again, delivering more thrust. Water meth was not as useful at sea level, where engines were torque (design) limited. At high elevation airfields, EGT limits your performance.

Recap by Tammy AI
In 2019 I flew one of Delta’s 777s ATL-CDG and back. It was fine and when I heard that Delta was retiring their 777s I was puzzled as the one I’d been on had a renovated look.
i find a 777 seats so narrow, unless its only Air France who use the narrow seats, Swiss air i find better with an A340, seats are wider and have more legroom,
My dad ran an aluminum recycling plant back in the early 50’s. They had an aluminum lithium alloy back then. He found that when they had a high lithium content the furnaces would shed all the dross that was stuck to the inside of the reverb furnaces. They didn’t check for lithium so he only found out after talking with others in the industry. The elevated lithium content didn’t seem to affect the properties of the alloys made with it.
@@TheUmbrex I believe the OP meant the Li did not affect the RECYCLED products that were made. If the recycled alloy was going to be made into kid toys and army canteens, the exact Li content was probably irrelevant.
@@drt1605There is enough lithium. CATL is about 50 percent capacity and waiting for EV manufacturers to order. New Li is being found routinely. It also recycles.
I think it has potential as more and more people travel to hot and high destinations like Mexico City. An over engined and over winged plane could be just what the doctor ordered to prevent heat delays from inadequate takeoff performance.
It makes sense that airlines weren't retiring their 777-300s early because they couldn't be converted to freighter, but now that IAI and Mammoth are working on 777 conversion programs, airlines might be more willing to get rid of their older 777s and replace them with the -8 once it comes out.

It's not happening. I don't understand why anyone would think so. -8 is smaller than -300ER. and got too much range for most operations. They either upgrade to -9 or downgrade to B787-10 HGW.
@@nntflow7058 Yeah the upgrade path for the 777-300 (ER) is the 777-9 and it's a plane that WILL sell great once Boeing is rolling them out because there are certain routes around the world where the 777-300ER dominates. This delay is screwing up Boeing's business. And NO, the 777-8 doesn't have TOO MUCH RANGE. That's laughable. You have to understand the routes that the 777-300ER flies to understand WHY those planes need a lot of range. The 777-9 for instance only adds about 250nm over the 777-300ER. Some of these routes are 7,500 - 8,000 miles so that doesn't leave a big buffer if it tries to land but then has to divert. So, if an airline can get by with a smaller plane the 777-8 would be fine. Otherwise they'll use the 777-9. And these planes are often flying into SE Asia from the US and weather can get bad VERY quickly in their summer time. ALL of these airlines that fly these VERY long flights from the US to Asia or Australia would not mind the extra range. I mean that's part of the reason why they bought the 777-300ER, NOT the 777-300. They seat about the same number of people.
yes this would be a really cool series to do, since the reasons why certain models don't sell is really insightful into how the aviation sector works as a whole, and can teach a lot of business lessons in general. If you'd be willing to go vintage, I'd like to learn more on why the L-1011 was a flop despite its major advancements
The DC-10 beat it to the market due to development delays. The L-1011 was also really expensive because of said advancements, airlines could have a similar size DC-10 for less and a larger 747 for just slightly more.
@@Vistamister that had nothing to do with. It that crash was a cfit control flight into terrain. The pilots were busy with a landing gear light bulb. And forgot to fly the airplane. The slow down was rolls Royce went bankrupt and delayed getting the engines
@@ljthirtyfiver bs there was one pilot error crash. The airplane was delayed when rolls Royce went bankrupt. L1011 was one of the safest planes built. It was away ahead of it’s time technology wise
True, BUT. Many airlines who hold large amount of slots in LAX or LHR (like BA or AA, United and Delta) actually operated small B767 and A330-200 or B787-8 between those routes. (JFK to LHR). So for them, they would just upgrade those smaller widebodies to B787-9/-10, A350-900/-1000, or A330-300 instead of using B777X or A350-1000.
Heard similar arguments/myths repeatedly upto about 10yrs ago re how 380 sales would improve/ "become popular again" "as space becomes more scare at major hubs like LAX or LHR...."etc. etc.... The inconvenient truth: The hot selling 321XLR narrowbody(I.e. the exact opposite of "bigger capacities planes") busted the myth once again that most long haul travel growth will occur only between major hubs/longhaul gateways.
@@felixli5279 You could say the A321XLR is the bigger capacity version of the A320 family ;) The next area to watch is whether we'll have enough pilots & other aircraft staff
I recently experienced the A350-9 and it’s an amazing aircraft, so futuristic. However I’m a huge fan of the 777s they the best commercial aircrafts ever built in my opinion. I love the size and sheer power of the engines. I hope Boeing doesn’t scrap the 8’s, having a 777 with that range would be a game changer. And of course a 777-10 would be a beast of an aircraft I would like to see.
I agree. The A350 is an amazing aircraft in many ways. However, for long haul international, I think the B777 in general is a better aircraft. The cabin just feels larger, and more solid lol
Jesus Christ is coming back! He wants to save you ❤ God is calling the lost to come to Him. Why? So He can give them everlasting life! We must repent before it’s too late. Accept and confess that Jesus Christ is your Lord and Saviour today! Now is the time, He’s the only way to heaven. God bless you.
I machined the front hub for the the GE90-155B & the GE 90-X engines which were smaller but produced more thrust than the GE 155B engines on the Boeing 787 aircraft. My my brother in law was a load master in Illinois who loaded the Boeing 727, ,747 B,-200 .747-400 , & 787, & Airbus cargo aircraft for UPS.
If there were a limited market for that length of fuselage then the best move would be to cut their losses. So long as the freight version is selling it is not a failure. Shame they didn't take the initiative to go for the new alloy but that's how calculated risk works.
When you buy a car, travel by train or commercial airline, cross a bridge, or ride an elevator - you are depending on the correct design, testing, manufacture/build, maintenance and operation of those items. As an end-user you have little or no insight into the first 4 stages - design, testing, manufacture/build, and maintenance. For that reason, manufacturers and operators need to be routinely checked for maintaining required standards, and held strictly to account for malpractice. Following the 737 MAX, its difficult for me to understand how anybody can assume that any Boeing will do 'what's written on the box'. The drivers of malpractice rarely get jailed, so it continues unabated.
The -8 is a freighter. :) As for the lighter aluminum, Boeing could just build a few for research out of that material and sell them discounted "for research" If the airlines like and show profit and fuel use improvements in their usage of those 777s that are made that way, go ahead and switch the material on the line. I also think a 777-11 could be made for ultra-long routes. (Capacity of -10 with more fuel tanks for long routes, or increased capacity) :)
Would a 777 built from AL-LI have to be re-certified? I think after the 737-MAX business Boeing cannot rely on a compliant US Certification regime to look the other way.
Id make a small correction, the 787 suffered from the Boeing Partner for Success Program. Had they kept it internally, probably wouldnt even have half as many issues
It would make an excellent airforce refueller with all that fuel and range. it would have an amazing loiter endurance for AWACS type ops. It’s takeoff performance would be a huge advantage for these type of operations as well. AND because it is designed with traditional materials, heavy modification would be a completely predictable process.
I believe the AWACS successor was annouced last year, the E-7 Wedgetail? There was a major need for speed of development as the E3s are getting very expensive to maintain. I think there was also a desire to get something on market, widely available across nato as the wole nato fleet is in a similar situation. Feels a bit rushed to me.
@jackpowell9276 you are correct and for the future E-7s this will be the E-7B which itself is a Max 7 that has the E-7 B737-700 equipment when will you can tell it apart from a Southwest Airlines Max 7 it's the radar on the back. Turn the B777-X into AEW RAF term for Awacs you would need to put the radar on the middle part which would make it like the E-3 Sentry or the A-50 used by the Russian and Indian militaries.
The 777er is a lovely aircraft and will be around a long time. When heavy it is limited to lower cruise altitudes. Airport operations limit the wing span of the 777 so the wing is not a perfect match for the heavier models. I am thinking the new wing span of the x will be an overall benefit and allow higher cruise altitudes.
Qantas selected the A350-1000 for its "Project Sunrise" - non stop Sydney and Melbourne to London and New York. The other contender was the 777-8. Even the "ludicrous range" did not clinch the deal. Would be good to include a comparison of the range of the A350-1000 and B777-8, as well as payloads, in the video.
778 was not available and would not have been. They were asking Qantas to wait for it till "whenever." the 778 was the superior plane for the route and I expect that Qantas will buy them if/when they see its performance numbers in operation. 35K will operate that route with 230pax or so, down considerably from its brochure capacity. 778 would have carried about 300 on the same mission. 789s are doing 7800nm segments with 235pax and a half ton of cargo on the reg now. ANZ is going to be pushing them to JKF, ORD, etc., from AKL. BA should have offered a 254t 788 - it would have done that route with about as many pax as the 35K.
@@bobjones-bt9bh if you track of the contest even 778 cannot do that with 300 pax! Qantas step down the requirments to 250. So 238 pax for 20h flight is not bad and it left 789 to carry it self to that distance!
my question is why didn't boeing just use the same composite fuselage as the 787 if they ironed out the problems already. its much lighter and efficient and would make the plane more tempting over an A350. oh yea the A350 ULR can fly 9700 nm which is almost 1000 more nm than the 777x. Crazy how good the A350-900 ULR is
Even if Boeing never sell a single dash-8, I can see psychological benefit for them for just offering it. Car companies do it all the time, offering a low sticker price on a model that almost nobody will actually buy. Of course, airlines won't be buying a dash-9 because of alloy wheels or a slightly nicer infotainment package for the pilot, but the reassurance of paying a little more to gain a few extra seats just in case, or avoiding seeing to be the ones to buy the 'budget' option should not be underestimated.
@@mmm0404 not with same pax count. 778 flies further by an hour or so. to put it in numbers, on the Sunrise route, the 778 would be able to take 300ish pax. Before sunrise was even firmed, I did estimates based on publicly available burn numbers on ULH 35K routes and I projected 230-240pax for Sunrise in A35K. Nailed it. 778 could take 300 over the same mission
@@bobjones-bt9bhYour calculations are way out. You fail to factor fuel burn and that the A350-1000 is 26 TONNES lighter than the 777-8 design. The Project Sunrise version will have 321T MTOW.
Given the similarities between the -8 and -9 and thus shared component, assembly line, etc. , Boeing can afford to wait an see a market develops for the -8 since there is little cost to do so. The MD-11 may be old but I find it a very good looking airplane. Driving into work you could tell that an MD-11 would soon be coming of the line since the vertical stabilizer would appear on the apron a day or so before the airplane.
Yup. Boeing don’t even have to wait and see how the market looks. They’re the exact same plane rolling off the exact same assembly lines, except one is 19ft longer. Am sure Boeing don’t really care which variant sells (they would if the -8 had smaller wings as is suggested here).
Despite intense lobbying from boeing to sell them its 777x, Philippine Airlines decided to replace its aging intercontinental workhorse fleet of 777-300 ERs with 9 A-350-1000s, the first of which will be delivered in the fourth quarter of 2025. it's a much better fit than the 777x. Philippine Airline's longest route (one of the 10 longest in the world) Manila-New York is being flown by an A-350-9. It will be replaced by the A-350-1000.
Was also thinking about the same thing throughout the video. Explains why PAL decided not to go with the 777x. Although,,, they ~could've considered the 779 instead. PAL used to be able to fill entire 747-400s before their 77Ws arrived. I don't think it's a stretch for PAL to be able to properly utilize the -9 even with its extra size compared to the 77W. ((Then again, the 35K really does seem to be the perfect 77W replacement anyway. I think PAL made the right call))
Philippine airlines only has 1 A350 900 as Marcos has taken control of the second one for his world wide party time. Hard to operate any airline with 1 of a type. Philippine airlines is so poorly run to begin with.
@@stevesmoneypit6137 diktajunior really is a huge pain in the ass for Filipino taxpayers. Him comandeering the A350 anytime he likes actually caused a friend of mine to have their premium economy seat (only available on the A350) downgraded to just regular economy when their aircraft got replaced by the 77W for their MNL-JFK flight. PAL even tried to hide it by writing the change in small font in their email to my friend. My friend ultimately got a free business class upgrade but had they not read the fine print, they would've gotten a crappy regular economy seat at a premium economy price.
@@stevesmoneypit6137 Choosing to take up one of the more plentiful older 77W’s would’ve been one small way to help claw back from his family’s horrific reputation. As a signal that the govt is trying at least to not put a bigger dent into the flag carrier’s already super tight operating margins. But of course, true to form …
on that, PAL originally had the 359 at 275t. They had to upgrade to 278 to do JFK-MNL reliably full. That gives some idea of real world ranges of 359s. That's a 7400nm mission.
40 units really isn’t that much, but it all depends on what the breakeven point for the -8 program is. If it only takes the sale of 20 planes to make up for the cost of research/development/labor/manufacturing expenses - then it makes sense to not cancel the program if you have 40 orders.
Yup, and on the flip side, Boeing just was not in a place to take a large risk after their MAX incident. This also seems like a relatively cheap upgrade compared to what it could have been.
I absolutely adore the 747-400, I wish they would reengineer it so the engines where larger and seriously fuel efficient…and perhaps reduce weight through composites..the upper deck is spacious, and the design of this plane is iconic and timeless. It will be missed by many.
It will be out of passenger service completely probably in the next five years. 10 at the most. But there will be 747 freighters flying for another three decades.
The 747 while being legendary did have some space limitations due to its shape. The cargo capacity is low on the 747-400 and the A340-600 and 777-300ER beats it by a healthy margin. The 777-300ER also has its advantage of having a fully circular fuselage, which allowed Boeing to reduce the amount of structure needed for the airframe.
Quantas just announced that they will use the A350-1000 for their project Sunrise flights. 777-8 is even not considered for the super long distance routes, which was the only remaining advantage of that flawed aircraft.
Low humidity does not equate to less dense air, the converse is true. Two variables affect aircraft performance, pressure altitude and density altitude, which is ambient air temperature and elevation of the runway.
777-10 is a good idea. But also not easy to take-off/land because of its long and low "tail". Pilots will have to wait two seconds longer after take-off to ascend steeper.
A couple of corrections. 777X does not have the most powerful engines. Actually some 300ERs have a higher power rating. Which is good news: with better aerodynamics it has to overcome less drag. Secondly, 777-8's range is not in a class of its own. Just about the same as A350-1000s. Which does not count for much. Commercially viable ultra long haul routes are few and far between. They positively require 2 major rich cities that will generate enough traffic volume that also has the purchasing power to pay high ticket prices. SIA's SIN-EWR route with A350-900ULR just carries 170 pax, rather than 310. Besides, such missions require 2 (two) full crews, and carries loads of extra fuel to be burned for the sole purpose of burning more fuel along the way. Hence such routes are necessarily very few. 777-8 is very similar to A330-800 and A319. All are shrunk versions with much bigger wings and engines than needed. This gives all 3 super field performance and very long range. But it does so at a heavy cost. Such designs are only competitive at their upper range limits. In the case of 777-8 at 7,500-8,000NM in still air. But as we saw such routes are tricky, they may or may not work, and a big rise in fuel prices will kill them for sure. Therefore when Qantas evaluated this plane vs A350-1000 it opted for Airbus with closed eyes, in the understanding that it can also be used for other trunk routes to Asia. Consequently having failed at 777-8's dream route, it will be difficult to find other viable options. The only ones would be LAX, SFO and maybe SEA and YVR from the ME3 bases in the Middle East. The freighter version will do fine, just the same as A350F that will sell well. 777-9 just as A350-1000 will sell only moderately. The double wheel and spoke like we had with JFK and LHR is gone for good, never to return. The market tendency today is towards somewhat smaller planes like A350-900 and 787-9&10, that can also cover good distances at competitive prices, and are easier to fill. During high seasons all planes fill up. The problem is during the low demand months.
The GE9x has a lower rated thrust of 105k, yes, but can actually push much higher in terms of max thrust (they set the record for most powerful jet engine a few years back). Another reason why making a -10 will be easy
The 777-200 was never a shrink of the 300. , the 300 is a stretch from the 200. The 332 is a true shrink, the 777-200 was the base model The 777-8 is a stretch from the 200LR. The 777-8 is just a Boeing version of the a350-1000 , and most airlines who have selected the 35K were more interested in its capacity rather than range. According to Boeing the 777-8 should have a 4% lower seat cost that the 35K, the main reason it's not selling is because Boeing has put it in the backburner
Point No.2 reminds me of the issues with the A380, where the Arabian Gulf state airlines also had a major influence, the Vickers VC-10, which was tailored to the needs of the then BOAC and made it uneconomical for other airlines, and Southwest Airlines influence on the B737 Max
Boeing’s decision to MAX the 737 was influenced by 2 airlines: Southwest and AA. Had Boeing gone clean sheet, it would’ve been interesting to see the reactions of other 737 users at that time like Alaska, Continental, Delta, KLM, Aeromexico, and Westjet.
@@Blank00 I*ll bet Boeing are kicking themselves for closing the 757 production line. This aircraft would have been a lot more suitable for modernisation and re-engining with more modern engines.
Nice video, but a couple of points... the idea that the 777-8F will take priority over the passenger variant isn't really new. It's not official, but it's been more or less a given since at least a year ago, when the release of the 777-9 was pushed to 2025. Secondly, the 737 MAX didn't make its 14% per-passenger gains SOLELY thanks to the new LEAP-1Bs. The new winglets are worth around 1.5%, and more impressively, the new tailcone and the APU door a whopping 3% (thanks, in part, to the omission of the VGs between the vertical and horizontal stabilizers). So all-in, the engines are 9-10%. Actual % of improvement depends on utilization factors like average range, load etc.
I don't know if the range argument is valid. Qantas is finalising plans to fly the longest nonstop routes on the planet in SYD-LHR and SYD-JFK and they are doing it in A350's.
Boeing should have built a 777-8 as a re-engined 777-200/ER/LR and the 777-9 as a re-engined 777-300/ER. Rather than stretching the length of the fuselage and having bigger wings. The 787-10 replacing the the 772s are just dumb due to the 781’s trash range and un-optimized airframe; and perhaps also that the 779’s 747-size is too big for the demand. The 777X should’ve been more simple.
CF saves tons of weight in the wings and allows superior wings. Sorry, you are just wrong. The only thing B did wrong is not use Al-Li for its fuselage. Which probably would only save weight on the rear portion of the fuselage where the rigidity is more problematic.
I am exactly the opposite of an expert on this subject, but I seem to recall - at least 20+ years ago that flying on the 767 was not a nice experience, whereas flying on a 777 was always a memorable experience.
Next video should be about the A319NEO, why its' selling so slow compared to it's predecessor (only 70 orders). The main reason is the A220-300, just being too similar & cheaper, but the backlog for the -300 variant is starting to pile-up, meaning extended delivery times.
You also see a similar trend with the 737s. Each generation the most popular variant of the previous generation becomes much less popular. The 200 was by far the biggest seller of the original series, yet the classic equivalent, the 500, sold poorly, with the larger 300 being the main seller. Then with the NGs, the 300 became the 700 and although it did outsell it's previous version, the longer 800 was by far the most successful. The trend for narrowbodies does seem to be to get bigger at each generation. The regional jets getting bigger and better ranges probably plays a role too.
The 787-8 is designed as an ultra-long range aircraft, to exceed the range of even the 77-200LR. That market is fickle and small. The main potential customer was QANTAS, with its desire to fly London-Sydney nonstop, and Emirates and Singapore both of which fly some very long-range routes. In many cases, making an ultra-long range airplane is done by applying the wing, engines, and gross weight of a larger model to a shorter fuselage. This was done with the 747SP, the L-1011-500, the A240-500, and the 777-200LR. This time, Airbus has taken a different approach. Instead of taking the A350-1000 and shrinking it, they increased the fuel capacity of the A350-900, and realizing these ultra-long range premium routes do not carry cargo (which can be more affordably carried by ordinary range aircraft with multiple intermediate stops), they deactivated the forward cargo hold. This produced the A350ULR. However, Airbus has made performance improvements to the A350 (New Production Standard, or NPS) that means new A350-900s have similar performance to the A350-900ULR. The NPS also improves the range performance of the A350-1000. The A350-900ULR and A350-900 NPS, and also the A350-1000 NPS, have been purchased for these markets. QANTAS recently selected the A350-1000 for its Project Sunrise. These will have additional 20,000 liters of fuel capacity and perhaps an increase in maximum takeoff weight. The 777-8 freighter has a slightly longer fuselage, which will be used on the passenger version as well. This should allow for one more row of seats, depending on the configuration. The 777-8 will probably mostly be produced as a freighter, the same way as the 777-200LR, which is the basis for the 777F.
It's easy for a company's image to take a hit, especially when the disaster surrounding the 737 Max was only four years ago. We all heard back then the stories about that concerns were ignored. Has the company addressed these accusations and recovered and improved safety in that short time?
Pilots have been dealing with that for a long time on the 737-800 and 900 which is incredibly easy to tailstrike. When I transitioned from the 737 to the 777 I felt a huge weight off my shoulders. How much longer would a -10 have to be to even come close to the small tail clearance of the -900 taking off at F1?
The other way of doing things is to go back to the old ways, have a special version for the mid east airlines and another for others. different engines and wings. Boeing used to do that with the 707, a tanker version for the military(narrow fuselage) then the 707, and the 707 came with various range capabilities and also Rolls Royce engines (for the British) or Pratt and Whitney. It is not the cheapest to engineer, but is better than no sales.
Explain what? The production of the 777-9 has been plagued with delays, including Covid which shut down factories for a time period, the FAA deciding it wanted to investigate how the FAA ITSELF was dealing with certifying planes, the production process itself had some issues, the engine they're using was delayed because of problems, etc.................. And the whole issue with the FFA stems from the 737 MAX having problems but was certified anyway but the plane has systems in it that should have required a different certification program vs. other 737s but it wasn't. There are NO delivered 777-8s or 777-9s. So, why are orders down? The large delays and airlines need planes NOW. The 777X has been a series of unfortunate events, part of which isn't the problem of the plane itself but instead the FAA causing a lot of delays and the issue with the engine. WHEN it gets certified AND Boeing ramps up production it will sell FINE because that plane is IDEAL for different routes. But once again airlines need planes NOW, so some have canceled orders to buy planes that can actually be manufactured NOW, minus of course the backup because of orders outpace production, and there is no other Boeing plane that can come close to what the 777 does so that means buying from Airbus. And this isn't because airlines feel the Airbus model they're buying is a better solution because most of the time it's not, but it's an acceptable solution giving the situation right now with the delays for the 777X. If an airliner for instance has mostly 777s already it would have been best to replace it with the 777X. The 777-300ER was a VERY successful plane and should have been mostly replaced with the 777-9 but they aren't delivering yet. And for people who fail to understand why an airline will often want to stick with a certain type, it's because of pilot training. It's easier for an airline to have the pilots it needs if you have minimal aircraft types, because a pilot has to train on whatever type they fly and an airline would rather not bounce a pilot between flying different types, so once a pilot is certified on a type they tend to fly that type for a long time. Also, these are LONG RANGE aircraft. They are used for LONG flights. You can THINK that an airline can get many years out of these but that's rarely the case. You get to the point of needing a major overhaul at some point and most airlines would rather buy a new plane rather than spend the money for that overhaul. It's expensive.
I would argue that the -8 is a nice, larger replacement for the -200LR. I could carry as many passengers (or more) than the A350-1000, much more cargo and have far less weight restrictions. I agree the future of this variant hangs on the success of ultra-longhauls.
The reason Boeing are not building the -8 is quite simple. The A350-1000 does its exact job and comes in some 26 TONNES lighter. That means it is technically obsolete as a design.
@@nathd1748how is it obsolete if the - 8 carries more payload and passengers than the 1000 with a comparable range and fuel burn AND better thrust to weight ratio lol? Weight isn't everything in a plane
@valet2972 It does not have comparable fuel burn. It requires 2x 110k output engines to do the job that the A350-1000 does with 2x 97k output engines. It is carrying about 26 TONNES of extra weight to do an almost on par job as the Airbus. You reckon lugging 26 extra tonnes is cost effective???
@@nathd1748 it does have a comparable fuel burn lol. Also it doesn’t need more powerful engines to do the job of the -1000, it has them to give it a higher thrust to weight ratio and carry more payload lol.
@valet2972 you can 'lol' all you like. The 777-8F has a 113T revenue payload. The A350-1000 had a MTOW bump in October 2023 to 322T giving the A350F a revenue payload of....113T!!!! The GE9X is currently not giving the fuel burn that they offered customers. Currently it is 1% over the XWB97 at a similar thrust output. So if the A350F is carrying 113T revenue payload but burning 6.2T average per hour over a given distance while the GE9x has to lug an extra 26T of body structure and burn 7.2T per hour to lug that same payload, then the 777-8F is going to be burning a TONNE of fuel per HOUR to shift the same load. If you cannot work out that the 777-8F is obsolete off those simple maths, then you are a FOOL.
There seems to also be the factor of if you’re going to buy a 777X, then why wouldn’t you just go with the -9, why constrain yourself with the smaller -8 that doesn’t really offer much advantage over the -9.
My last 777 flight was American Airlines Rio de Janeiro to New York. The plane felt so futuristic that it reminded me of the movie 2001. I really loved the experience.
@@vincevanderperre8660 I have flown the 380 from New York to Singapore. Excellent experience though I found issue with the engineering. I think on Airbus smaller aircraft the fly by wire system can feel jerky.
By far the most expensive part of an aircraft family is the manufacturing infrastructure and logistics networks. Since Boeing already has it, they would be foolish to abandon all the tooling and supply networks they set up. The air freight industry has been booming at a ridiculous rate and they can just focus on 777 freighters.
I think that the 777-8 will sell if Boeing start to use the AlLi alloy, this will lower the overall weight of the airframe, allowing the plane to fly at higher altitudes and reduce fuel burn. I would also say that the 777-8 could be a good replacement for the -200ER because of crew familiarization and the wider cabin giving airlines more space to be more innovative with their onboard products.
I beg differ, a little. If they switch to AlLi alloy for any version of 777-8, I think they should do the same for later 777-9 productions. I think Boeing 777-9 has a fine balance of capacity and range, but underpowered at the same time. I expect Boeing will do the 777-9ER anytime soon.
@@talesfromunderthemoon The only issue with changing the 777-9 to al-li right now is that the 777-9 is already 5 years delayed and airlines like Emirates and Lufthansa will have a cow if it were to be delayed any further. The 777X would likely have to restart the certification process which would push back deliveries by years not months.
@@cobyexplanes Airbus launched a modernized NPS version of the A350 last year so I see no reason why Boeing can't do the same. It will be expensive in the short term but the potential fuel savings may make the 777X more efficient than the A350 and net them more sales in the long term.
The larger span of the 777X and the much more efficient GE9X engines are the dominant parameters here. The troubled surface roughness of the AB 350 fuselage is detrimental to the efficiency.
The GE9X will be rated at 110k lb. On ground testing it maxed out at 134.3 k lb. The GE90 now in service is rated at 115k lb. So in standard service the GE9X won’t be the most powerful engine flying. The B777-8 will enter service after the B777-8F. This was discussed in the press over a year ago.
Al-Li alloys became famous in the 'sixties when it was used to save weight on fighters, mainly in undercarriage components. Thing were fine until it rained, and the undercarriage collapsed.
AL-Li is a bad idea. I remember years ago working for a company that was thinking about switching their skins to it. It turns out, it is much more brittle and the damage tolerance tradeoff isn't worth it. It is a nice science project, but it doesn't seem like it is truly a viable alternative.
It's the same issue they had with the 777-200LR. They are doing the same thing here and turning it to the F version which in the has sold sold well so far in a short amount time. They have already said some months ago the F is first and the passenger is on hold. Boeing is not committed to building the 8 passenger version and said as much a couple of years go. Where you right it's simply too heavy. That's nothing unusual in the industry. We've seen it from both Airbus and Boeing in the 350-800, 330-8 NEO and earlier with Boeing with the 767-200 etc etc. We've also seen it with the 380 with too much built in wait to support a larger version there was no market for. This isn't anything new.
IIRC, Aluminum-Lithium alloys have a non-orthogonal fracture mode. Installing bolts into interference fit holes exposed this issue on the first prototypes. Fortunately, long before the first flight. And all parts using Aluminum-Lithium alloys, including secondary non-structural parts were redesigned to use conventional aluminum alloys.
I think they will be happy with the program overall if the sales of the -8F and the -9P are strong enough. It doesn't cost THAT much more to validate the design of the -8 in the grand scheme of the overall program. If they make a -10 and it is successful as well, even better. I'm sure Boeing is more concerned with the overall 777X program. They need to get the delays under control and get the program in the air making money for airlines. If they can make it work, the -8P poor sales won't really matter.
They are going to be what... 5 years late? That has cost them billions and makes them look amateur next to the time it took Airbus to get the A350 approved. Just one of the delay charges was $6.3 billion, and there was at least one more of $1.2 billion in that year. I believe their original development budget was $5 billion. So once again they've blown their development costs by more than 100%. I haven't see a complete accounting for Boeing's charges for amateur engineering mistakes recently. The MAX debacle cost them way over $10B and the 787 program was $24 billion over the $10 billion budget by the time it was approved.
for me the 777-8 is at the same situation with 777-200LR and A330-800. have less seats but very long range flights so it's not suitable with most airliners, some use a smaller aircraft like 787-10 or A330-900, may have less seats but more efficient than 777-8, maybe will have a future orders most likely will BBJ, some privet airlines need long range aircraft but not oversized like 777-9, or if have very bad luck end up like what happened with 767-400ER
Exactly. They are behind with all their latest designs. Didn’t use new techniques or materials… Boeing is a mess. The only thing they can focus on, is on a completely new designed aircraft that flies ways faster, while not using more fuel (efficiency). Like a big Concorde that isn’t drinking fuel like a thirsty lion. This way they will be on top again It’s time for actual new generation aircraft. All current next gen planes are basically the same thing… with more efficient engines and lighter materials.
I couldn't agree more. The 777-200LR had much more range potential than the 777-300ER. Apparently the airlines decided that more seats trumped longer range. I expect that the final best seller of the 777X series is a -9 with longer range. Why would anyone chose the 777X over the A350? With the 777 you get GE engines.
It has one this going for it that has traditionally been an Airbus selling point: commonality. Operators of other 777 variants will save on operating and training costs by choosing it over the A350-1000 even if the latter is abetter optimised aircraft for its payload in absolute terms. Non-ideal variants of other aircraft have sold in certain quantities for the same reason; operators of A320-family aircraft have bought A318s instead of the biggest CRJs in the around 100 seat market because of the streamlined operations that allows, even though the A318 is ludicrously over-winged and over-engined. Some A320 operators are however now coming round to the A220 now because of that (AF is replacing A318s with A220s)...
The original A330-300 didn’t sell shit either, then Airbus released the shortened -200 which was doing pretty well and then the market changed and everybody and it’s grandma all of a sudden wanted a -300. Don’t write off the -8 just yet.
They have built a modern day VC10, a plane that had considerable better hot and high performance over the 707/DC8 but at the expense of a higher operating cost.
I would like to see if FedEx eventualy orders the -8F, which may be helped with the announcement of the MD-11 retirements. I would like to make this a series.
Without question the A350 is the most advanced airliner in the world. Everything from its maintenance on board computers, reliable components and sheer range and efficiency thanks to Rolls Royce pulling that out of the hat, clearly has Boeing trailing in its wake.
Does the 777-8 have the potential to replace the 757? One application would be to replace the 757s that are used for the U.S. President and Vice President to fly into smaller airports with shorter runways. If it can replace the 757 (with comparable engine thrust and lift), despite it being a wide-body, couldn't that open up a possible market? I feel as though I am unintentionally missing a big piece of my overall thoughts here.
I'd think the 737 Max 10 would be a better replacement for the Boeing C-32 (USAF POTUS transport based on the 757) It's almost as big and has the same range with the same passenger capacity. The other way to go would be a 787-8, even though the 787 is twice the weight of the 757 and has MUCH longer range).
Why ? Because one of these costs over $500m+ a piece. That’s before you even put an interior or livery on the outside, Not many airlines can afford let alone justify the stupendous price for a 777-8. For an airline to make back that cost it would have to sell out all tickets with average picket price of $2500. Over 14months before ebitda.
Small correction to make - while the GE9X engine on the new 777s is larger, it is actually slightly less powerful than the GE90 engines used on current 777s.
The GE9X bested the maximum thrust record of the GE90-115b. The nominal rating is lower (105k vs 115k) because the aerodynamics of the new 777X doesn't require that much thrust.
@@trackrat62 The stress test is irrelevant to the rated limits of each engine. The GE90 is rated higher like you said. The GE9X is not rated lower because of the aerodynamics, that's a silly reason. The GE9X is rated lower because it's more fuel efficient to make tradeoffs of power it doesn't need with regards to compression and fuel ratios and blade design. Regardless, it is a less powerful design than the GE90 like I said.
A-380 had the same type of problem. It was the baseline model, with bigger engines & wing than what was needed for that fuselage. There was supposed to be a new, bigger model to expand into the wing & engines but the twin jets killed it.
Ddi't the A380 suffer from the same problem? The wingbox and wing were designed for a longer fuselage, but only the shortest version was ever ordered and built, so it got stuck looking like a chubby boi.
Boeing built the C-17 which has a lithium aluminum body with a composite tail, it was a cost/time saving to keep the777 body close to the original 777.
I imagine it would be a significant engineering cost to re-develop the fuselage of the 777-8, but wouldn’t a narrower yet longer fuselage accommodate a similar, or slightly lower, passenger count while measurably improving the plane’s aerodynamics and flight efficiency?
This would lterally mean a new model. If they were trying to do that, a much easier way would be to try to stretch the barrower fuselage that Boeing already has AND is much more modern to create 787-11.
Air new zealand coukd use the 777-8. Their akl-jfk flight is really stretching the linit of the 787-9 - several trips have had to be diverted because of headwinds. Also they plan to replace their 777-300 with 787-10 which have smaller capacity and way shorter range.
I think the A350-1000 has also the reason why it's selling less than the -900, poor timing to replace the 777-300ER, which is obviously not that old. It only replaced the similar-sized Quad-Engined A340-600, which has a reputation for being SUCH a GAS GUZZLER for having 4 engines, and only a HANDFUL of airlines operated the -600, and replaced it with the -1000. And some airlines that also had the aging Non-ER 777-300s also replaced them with the -1000.
I agree, however the -900 had more orders over its lifetime
777-300s perfect for intra Asian high density routes. CX best example. EK only had 4 or so.
I wouldn't agree about the non-ER for now. CX still holds on their -300s, Thai didn't get -1000s, neither did SQ, Korean, ANA. JAL ordered A35Ks to replace 300ER's. Correct me if I'm wrong

Small correction at 5:59 , low humidity is actually a desirable factor to generate thrust. Also these carriers are all based at sea level which helps a lot with performance (the air is a lot denser). But overall you’re right, hot summer take offs in the UAE at MTOW can be close to the limits
Yes, and no. Humidity can both be beneficial and detrimental.
As water is not compressable, ingested into the main air stream, it can produce more thrust because of how much water expands when it turns into steam. Higher pressure in the turbine section creates more thrust.
Before high bypass engines were a thing, some airplanes literally had water tanks on board, that would inject water into the engine to produce more thrust during take off. B707 was one.
A modern engine produces more thrust on a rainy day than on a sunny day. It's not a massive amount, but measurable and noticable.
he must've meant high humidity. Anyone who has been to the Gulf knows its incredibly humid
Even so, longer runways help a bit. The problem is not a given type of plane being unable to take off. Rather, than in so doing the engines have to be used at full throttle, and that means more rpms and at higher engine heat, which increases maintenance costs and decreases engine life. Actually Emirates chose (before changing their mind) 787-10s, which have substantially poorer field performance.
It worth noting that a lot of these middle eastern aircraft will also be aiming to link their hubs with smaller European airports. High performance will allow for more routes to be created.
@@CerberusTenshi Humidity represents water as a vapour. ie. a gas. Consisting of 2 hydrogen molecules (top left corner of periodic table) plus 1 molecule oxygen, it’s lighter and less dense than the largely nitrogen/ oxygen air. Less density equals less performance.
We operated the B747SP with water meth injection. This was injected as a liquid, which is different to humidity. This lowered the EGT (exhaust gas temperatures), thus allowing for more fuel to be added till EGT limits were reached once again, delivering more thrust.
Water meth was not as useful at sea level, where engines were torque (design) limited. At high elevation airfields, EGT limits your performance.
I also want to point out that summers here in the Gulf are hot and VERY humid, rather than lacking humidity.
Yeah, I worked in Salalah, Oman. During the Monsoon it usually had 100% humidity

Recap by Tammy AI
i got lost
In 2019 I flew one of Delta’s 777s ATL-CDG and back. It was fine and when I heard that Delta was retiring their 777s I was puzzled as the one I’d been on had a renovated look.
Delta should have continued flying them, and they should have also ordered a fleet of Boeing 777-300ER jetliners.
i find a 777 seats so narrow, unless its only Air France who use the narrow seats, Swiss air i find better with an A340, seats are wider and have more legroom,
My dad ran an aluminum recycling plant back in the early 50’s. They had an aluminum lithium alloy back then. He found that when they had a high lithium content the furnaces would shed all the dross that was stuck to the inside of the reverb furnaces. They didn’t check for lithium so he only found out after talking with others in the industry. The elevated lithium content didn’t seem to affect the properties of the alloys made with it.
Adding lithium to aluminum reduces density (wt.) and increases stiffness, but makes it very expensive and limits it use.
it´s like u didn't watch the video
@@TheUmbrex I believe the OP meant the Li did not affect the RECYCLED products that were made. If the recycled alloy was going to be made into kid toys and army canteens, the exact Li content was probably irrelevant.
@@drt1605There is enough lithium. CATL is about 50 percent capacity and waiting for EV manufacturers to order. New Li is being found routinely. It also recycles.
I think it has potential as more and more people travel to hot and high destinations like Mexico City. An over engined and over winged plane could be just what the doctor ordered to prevent heat delays from inadequate takeoff performance.
It makes sense that airlines weren't retiring their 777-300s early because they couldn't be converted to freighter, but now that IAI and Mammoth are working on 777 conversion programs, airlines might be more willing to get rid of their older 777s and replace them with the -8 once it comes out.

It's not happening. I don't understand why anyone would think so. -8 is smaller than -300ER. and got too much range for most operations.
They either upgrade to -9 or downgrade to B787-10 HGW.
@@nntflow7058 Yeah the upgrade path for the 777-300 (ER) is the 777-9 and it's a plane that WILL sell great once Boeing is rolling them out because there are certain routes around the world where the 777-300ER dominates.
This delay is screwing up Boeing's business.
And NO, the 777-8 doesn't have TOO MUCH RANGE. That's laughable. You have to understand the routes that the 777-300ER flies to understand WHY those planes need a lot of range. The 777-9 for instance only adds about 250nm over the 777-300ER. Some of these routes are 7,500 - 8,000 miles so that doesn't leave a big buffer if it tries to land but then has to divert. So, if an airline can get by with a smaller plane the 777-8 would be fine. Otherwise they'll use the 777-9.
And these planes are often flying into SE Asia from the US and weather can get bad VERY quickly in their summer time.
ALL of these airlines that fly these VERY long flights from the US to Asia or Australia would not mind the extra range. I mean that's part of the reason why they bought the 777-300ER, NOT the 777-300. They seat about the same number of people.

I feel like as space becomes more scarce at major hubs like LAX or LHR, these bigger capacity planes may become popular again for hub to hub routes.
True, BUT. Many airlines who hold large amount of slots in LAX or LHR (like BA or AA, United and Delta) actually operated small B767 and A330-200 or B787-8 between those routes. (JFK to LHR).
So for them, they would just upgrade those smaller widebodies to B787-9/-10, A350-900/-1000, or A330-300 instead of using B777X or A350-1000.

When you buy a car, travel by train or commercial airline, cross a bridge, or ride an elevator - you are depending on the correct design, testing, manufacture/build, maintenance and operation of those items. As an end-user you have little or no insight into the first 4 stages - design, testing, manufacture/build, and maintenance. For that reason, manufacturers and operators need to be routinely checked for maintaining required standards, and held strictly to account for malpractice. Following the 737 MAX, its difficult for me to understand how anybody can assume that any Boeing will do 'what's written on the box'. The drivers of malpractice rarely get jailed, so it continues unabated.

I recently flew on an Airbus and I remembered how much I enjoy flying in an Airbus. Not sure if it’s the seating but I find them better than Boeing.
They need to bring back the 757 ER. Best overall platform and very flexible in terms of range and comfort.
The -8 is a freighter. :) As for the lighter aluminum, Boeing could just build a few for research out of that material and sell them discounted "for research" If the airlines like and show profit and fuel use improvements in their usage of those 777s that are made that way, go ahead and switch the material on the line. I also think a 777-11 could be made for ultra-long routes. (Capacity of -10 with more fuel tanks for long routes, or increased capacity) :)
Would a 777 built from AL-LI have to be re-certified? I think after the 737-MAX business Boeing cannot rely on a compliant US Certification regime to look the other way.
by all logic, a hypothetical 777-10 with more tanks is going to be a 777-10ER. Also, more tanks is literally what specifically ruined the B77L.
@@oldcynic6964 that would literally be an all-new airliner. You cannot call that a 777 anymore
Id make a small correction, the 787 suffered from the Boeing Partner for Success Program. Had they kept it internally, probably wouldnt even have half as many issues
Outsourcing is usually a bad idea.
It would make an excellent airforce refueller with all that fuel and range. it would have an amazing loiter endurance for AWACS type ops. It’s takeoff performance would be a huge advantage for these type of operations as well. AND because it is designed with traditional materials, heavy modification would be a completely predictable process.
I believe the AWACS successor was annouced last year, the E-7 Wedgetail? There was a major need for speed of development as the E3s are getting very expensive to maintain. I think there was also a desire to get something on market, widely available across nato as the wole nato fleet is in a similar situation. Feels a bit rushed to me.
@jackpowell9276 you are correct and for the future E-7s this will be the E-7B which itself is a Max 7 that has the E-7 B737-700 equipment when will you can tell it apart from a Southwest Airlines Max 7 it's the radar on the back. Turn the B777-X into AEW RAF term for Awacs you would need to put the radar on the middle part which would make it like the E-3 Sentry or the A-50 used by the Russian and Indian militaries.
The 777er is a lovely aircraft and will be around a long time.
When heavy it is limited to lower cruise altitudes. Airport operations limit the wing span of the 777 so the wing is not a perfect match for the heavier models.
I am thinking the new wing span of the x will be an overall benefit and allow higher cruise altitudes.
Probably takeoff weight is a more important factor.
Qantas selected the A350-1000 for its "Project Sunrise" - non stop Sydney and Melbourne to London and New York. The other contender was the 777-8. Even the "ludicrous range" did not clinch the deal. Would be good to include a comparison of the range of the A350-1000 and B777-8, as well as payloads, in the video.
778 was not available and would not have been. They were asking Qantas to wait for it till "whenever." the 778 was the superior plane for the route and I expect that Qantas will buy them if/when they see its performance numbers in operation. 35K will operate that route with 230pax or so, down considerably from its brochure capacity. 778 would have carried about 300 on the same mission. 789s are doing 7800nm segments with 235pax and a half ton of cargo on the reg now. ANZ is going to be pushing them to JKF, ORD, etc., from AKL.
BA should have offered a 254t 788 - it would have done that route with about as many pax as the 35K.
You get that information on Wikipedia, dipossum, in great detail .
@@bobjones-bt9bh if you track of the contest even 778 cannot do that with 300 pax! Qantas step down the requirments to 250. So 238 pax for 20h flight is not bad and it left 789 to carry it self to that distance!
Imagine the takeoff performance tho if you’re on a -8 on an unpopular, shorter-route flight out of a cool climate airport :-D
ZOOOOOM!!
my question is why didn't boeing just use the same composite fuselage as the 787 if they ironed out the problems already. its much lighter and efficient and would make the plane more tempting over an A350. oh yea the A350 ULR can fly 9700 nm which is almost 1000 more nm than the 777x. Crazy how good the A350-900 ULR is
It is evident that you did an amazing amount of research and made an amazing effort in producing this video.
Even if Boeing never sell a single dash-8, I can see psychological benefit for them for just offering it.
Car companies do it all the time, offering a low sticker price on a model that almost nobody will actually buy. Of course, airlines won't be buying a dash-9 because of alloy wheels or a slightly nicer infotainment package for the pilot, but the reassurance of paying a little more to gain a few extra seats just in case, or avoiding seeing to be the ones to buy the 'budget' option should not be underestimated.
Longer wings = Higher aspect ratio, gives you a small + in efficiency (similar to the E2s)
I teach Chinese language in a creative and funny way. Interest is the best teacher.
When you have the 787-10... the 777-8 kind of fits in there
eh, not really. the 777-8 is still quite a bit larger in every dimension (including seat count), and can fly *much* further
It is actually a good point, there are very few airlines needing the range and the 777-8 need to exist before it can fly further than the 787-10.
The 777-8 and a350-1000 have a similar range thou ,
@@mmm0404 not with same pax count. 778 flies further by an hour or so. to put it in numbers, on the Sunrise route, the 778 would be able to take 300ish pax. Before sunrise was even firmed, I did estimates based on publicly available burn numbers on ULH 35K routes and I projected 230-240pax for Sunrise in A35K. Nailed it. 778 could take 300 over the same mission
@@bobjones-bt9bhYour calculations are way out. You fail to factor fuel burn and that the A350-1000 is 26 TONNES lighter than the 777-8 design. The Project Sunrise version will have 321T MTOW.
Low humidity is favorable to generation of lift. Dry air is denser than humid air.
The heat is a problem, though.
Given the similarities between the -8 and -9 and thus shared component, assembly line, etc. , Boeing can afford to wait an see a market develops for the -8 since there is little cost to do so. The MD-11 may be old but I find it a very good looking airplane. Driving into work you could tell that an MD-11 would soon be coming of the line since the vertical stabilizer would appear on the apron a day or so before the airplane.
Yup. Boeing don’t even have to wait and see how the market looks. They’re the exact same plane rolling off the exact same assembly lines, except one is 19ft longer. Am sure Boeing don’t really care which variant sells (they would if the -8 had smaller wings as is suggested here).
Despite intense lobbying from boeing to sell them its 777x, Philippine Airlines decided to replace its aging intercontinental workhorse fleet of 777-300 ERs with 9 A-350-1000s, the first of which will be delivered in the fourth quarter of 2025. it's a much better fit than the 777x. Philippine Airline's longest route (one of the 10 longest in the world) Manila-New York is being flown by an A-350-9. It will be replaced by the A-350-1000.
Was also thinking about the same thing throughout the video. Explains why PAL decided not to go with the 777x.
Although,,, they ~could've considered the 779 instead. PAL used to be able to fill entire 747-400s before their 77Ws arrived. I don't think it's a stretch for PAL to be able to properly utilize the -9 even with its extra size compared to the 77W.
((Then again, the 35K really does seem to be the perfect 77W replacement anyway. I think PAL made the right call))
Philippine airlines only has 1 A350 900 as Marcos has taken control of the second one for his world wide party time. Hard to operate any airline with 1 of a type. Philippine airlines is so poorly run to begin with.
@@stevesmoneypit6137 diktajunior really is a huge pain in the ass for Filipino taxpayers.
Him comandeering the A350 anytime he likes actually caused a friend of mine to have their premium economy seat (only available on the A350) downgraded to just regular economy when their aircraft got replaced by the 77W for their MNL-JFK flight. PAL even tried to hide it by writing the change in small font in their email to my friend. My friend ultimately got a free business class upgrade but had they not read the fine print, they would've gotten a crappy regular economy seat at a premium economy price.
@@stevesmoneypit6137
Choosing to take up one of the more plentiful older 77W’s would’ve been one small way to help claw back from his family’s horrific reputation. As a signal that the govt is trying at least to not put a bigger dent into the flag carrier’s already super tight operating margins.
But of course, true to form …
on that, PAL originally had the 359 at 275t. They had to upgrade to 278 to do JFK-MNL reliably full. That gives some idea of real world ranges of 359s. That's a 7400nm mission.
I’ve seen them in person. They’re beautiful.
40 units really isn’t that much, but it all depends on what the breakeven point for the -8 program is. If it only takes the sale of 20 planes to make up for the cost of research/development/labor/manufacturing expenses - then it makes sense to not cancel the program if you have 40 orders.
Yup, and on the flip side, Boeing just was not in a place to take a large risk after their MAX incident. This also seems like a relatively cheap upgrade compared to what it could have been.
I absolutely adore the 747-400, I wish they would reengineer it so the engines where larger and seriously fuel efficient…and perhaps reduce weight through composites..the upper deck is spacious, and the design of this plane is iconic and timeless.
It will be missed by many.
It will be out of passenger service completely probably in the next five years. 10 at the most. But there will be 747 freighters flying for another three decades.
The 747 while being legendary did have some space limitations due to its shape. The cargo capacity is low on the 747-400 and the A340-600 and 777-300ER beats it by a healthy margin.
The 777-300ER also has its advantage of having a fully circular fuselage, which allowed Boeing to reduce the amount of structure needed for the airframe.
@@worldlinerai I get it…however flying on the upper deck in business class to Singapore from the US was a dream…
Quantas just announced that they will use the A350-1000 for their project Sunrise flights. 777-8 is even not considered for the super long distance routes, which was the only remaining advantage of that flawed aircraft.
Flawed aircraft? 😂
Low humidity does not equate to less dense air, the converse is true. Two variables affect aircraft performance, pressure altitude and density altitude, which is ambient air temperature and elevation of the runway.
777-10 is a good idea. But also not easy to take-off/land because of its long and low "tail". Pilots will have to wait two seconds longer after take-off to ascend steeper.
The 777-10 will have to have a "curb feeler", tail strike skid to protect the fuselage against over-rotation during takeoff and high alpha landing. 🤠
I thought about this too, aside the Ge9x the wings are massive
A couple of corrections. 777X does not have the most powerful engines. Actually some 300ERs have a higher power rating. Which is good news: with better aerodynamics it has to overcome less drag. Secondly, 777-8's range is not in a class of its own. Just about the same as A350-1000s. Which does not count for much. Commercially viable ultra long haul routes are few and far between. They positively require 2 major rich cities that will generate enough traffic volume that also has the purchasing power to pay high ticket prices. SIA's SIN-EWR route with A350-900ULR just carries 170 pax, rather than 310. Besides, such missions require 2 (two) full crews, and carries loads of extra fuel to be burned for the sole purpose of burning more fuel along the way. Hence such routes are necessarily very few. 777-8 is very similar to A330-800 and A319. All are shrunk versions with much bigger wings and engines than needed. This gives all 3 super field performance and very long range. But it does so at a heavy cost. Such designs are only competitive at their upper range limits. In the case of 777-8 at 7,500-8,000NM in still air. But as we saw such routes are tricky, they may or may not work, and a big rise in fuel prices will kill them for sure. Therefore when Qantas evaluated this plane vs A350-1000 it opted for Airbus with closed eyes, in the understanding that it can also be used for other trunk routes to Asia. Consequently having failed at 777-8's dream route, it will be difficult to find other viable options. The only ones would be LAX, SFO and maybe SEA and YVR from the ME3 bases in the Middle East. The freighter version will do fine, just the same as A350F that will sell well. 777-9 just as A350-1000 will sell only moderately. The double wheel and spoke like we had with JFK and LHR is gone for good, never to return. The market tendency today is towards somewhat smaller planes like A350-900 and 787-9&10, that can also cover good distances at competitive prices, and are easier to fill. During high seasons all planes fill up. The problem is during the low demand months.
The GE9x has a lower rated thrust of 105k, yes, but can actually push much higher in terms of max thrust (they set the record for most powerful jet engine a few years back). Another reason why making a -10 will be easy
The 777-200 was never a shrink of the 300. , the 300 is a stretch from the 200.
The 332 is a true shrink, the 777-200 was the base model
The 777-8 is a stretch from the 200LR.
The 777-8 is just a Boeing version of the a350-1000 , and most airlines who have selected the 35K were more interested in its capacity rather than range.
According to Boeing the 777-8 should have a 4% lower seat cost that the 35K, the main reason it's not selling is because Boeing has put it in the backburner
Is it higher than the 134k lbs of thrust the 9X was recorded to have?
@@mmm0404 I'm pretty sure that even though the 777-300 might be a stretch from the 777-200ER, the 777-8 is actually a shrink of the 777-9.
Point No.2 reminds me of the issues with the A380, where the Arabian Gulf state airlines also had a major influence, the Vickers VC-10, which was tailored to the needs of the then BOAC and made it uneconomical for other airlines, and Southwest Airlines influence on the B737 Max
Boeing’s decision to MAX the 737 was influenced by 2 airlines: Southwest and AA. Had Boeing gone clean sheet, it would’ve been interesting to see the reactions of other 737 users at that time like Alaska, Continental, Delta, KLM, Aeromexico, and Westjet.
@@Blank00 I*ll bet Boeing are kicking themselves for closing the 757 production line. This aircraft would have been a lot more suitable for modernisation and re-engining with more modern engines.
Nice video, but a couple of points... the idea that the 777-8F will take priority over the passenger variant isn't really new. It's not official, but it's been more or less a given since at least a year ago, when the release of the 777-9 was pushed to 2025. Secondly, the 737 MAX didn't make its 14% per-passenger gains SOLELY thanks to the new LEAP-1Bs. The new winglets are worth around 1.5%, and more impressively, the new tailcone and the APU door a whopping 3% (thanks, in part, to the omission of the VGs between the vertical and horizontal stabilizers). So all-in, the engines are 9-10%. Actual % of improvement depends on utilization factors like average range, load etc.
They need to cancel the -8, -9, -10, and the “Max” program.
I don't know if the range argument is valid. Qantas is finalising plans to fly the longest nonstop routes on the planet in SYD-LHR and SYD-JFK and they are doing it in A350's.
Boeing should have built a 777-8 as a re-engined 777-200/ER/LR and the 777-9 as a re-engined 777-300/ER. Rather than stretching the length of the fuselage and having bigger wings. The 787-10 replacing the the 772s are just dumb due to the 781’s trash range and un-optimized airframe; and perhaps also that the 779’s 747-size is too big for the demand. The 777X should’ve been more simple.
CF saves tons of weight in the wings and allows superior wings. Sorry, you are just wrong. The only thing B did wrong is not use Al-Li for its fuselage. Which probably would only save weight on the rear portion of the fuselage where the rigidity is more problematic.
I am exactly the opposite of an expert on this subject, but I seem to recall - at least 20+ years ago that flying on the 767 was not a nice experience, whereas flying on a 777 was always a memorable experience.
why?
@@Kelvin-ed6ce go figure
Next video should be about the A319NEO, why its' selling so slow compared to it's predecessor (only 70 orders). The main reason is the A220-300, just being too similar & cheaper, but the backlog for the -300 variant is starting to pile-up, meaning extended delivery times.
You also see a similar trend with the 737s. Each generation the most popular variant of the previous generation becomes much less popular. The 200 was by far the biggest seller of the original series, yet the classic equivalent, the 500, sold poorly, with the larger 300 being the main seller. Then with the NGs, the 300 became the 700 and although it did outsell it's previous version, the longer 800 was by far the most successful. The trend for narrowbodies does seem to be to get bigger at each generation. The regional jets getting bigger and better ranges probably plays a role too.
The 787-8 is designed as an ultra-long range aircraft, to exceed the range of even the 77-200LR. That market is fickle and small. The main potential customer was QANTAS, with its desire to fly London-Sydney nonstop, and Emirates and Singapore both of which fly some very long-range routes. In many cases, making an ultra-long range airplane is done by applying the wing, engines, and gross weight of a larger model to a shorter fuselage. This was done with the 747SP, the L-1011-500, the A240-500, and the 777-200LR.
This time, Airbus has taken a different approach. Instead of taking the A350-1000 and shrinking it, they increased the fuel capacity of the A350-900, and realizing these ultra-long range premium routes do not carry cargo (which can be more affordably carried by ordinary range aircraft with multiple intermediate stops), they deactivated the forward cargo hold. This produced the A350ULR. However, Airbus has made performance improvements to the A350 (New Production Standard, or NPS) that means new A350-900s have similar performance to the A350-900ULR. The NPS also improves the range performance of the A350-1000. The A350-900ULR and A350-900 NPS, and also the A350-1000 NPS, have been purchased for these markets. QANTAS recently selected the A350-1000 for its Project Sunrise. These will have additional 20,000 liters of fuel capacity and perhaps an increase in maximum takeoff weight.
The 777-8 freighter has a slightly longer fuselage, which will be used on the passenger version as well. This should allow for one more row of seats, depending on the configuration.
The 777-8 will probably mostly be produced as a freighter, the same way as the 777-200LR, which is the basis for the 777F.
I flew on an Air Canada 777 once and I have never been in such a huge aircraft that felt so small.
what a 777 is massive it’s engines are bigger than a human
It's easy for a company's image to take a hit, especially when the disaster surrounding the 737 Max was only four years ago. We all heard back then the stories about that concerns were ignored. Has the company addressed these accusations and recovered and improved safety in that short time?
Present day they are screwed again with a door plug issue and within days of that a engine fire and a lost wheel- seems a yugo is more reliable
I can imagine tail strikes on rotation on a 777x dash 10 being something to keep in mind.
I'm sure Boeing wil have a software fix for that........
That’s why the 777-300-er have a tail skid. It absorbs the hit from a tail strike the -200 did not have one. From a retired 777 mechanic
Pilots have been dealing with that for a long time on the 737-800 and 900 which is incredibly easy to tailstrike. When I transitioned from the 737 to the 777 I felt a huge weight off my shoulders. How much longer would a -10 have to be to even come close to the small tail clearance of the -900 taking off at F1?
7:37 "In a vacuum the jet may be worth buying..."
except in a vacuum there would be no airflow over the wings to give it lift... ^_^
I think the 787-10 would be a good selection for another video like this.
The other way of doing things is to go back to the old ways, have a special version for the mid east airlines and another for others. different engines and wings. Boeing used to do that with the 707, a tanker version for the military(narrow fuselage) then the 707, and the 707 came with various range capabilities and also Rolls Royce engines (for the British) or Pratt and Whitney. It is not the cheapest to engineer, but is better than no sales.
How about an option for fuselage material,
while you're at it :)
Making a -10 would be the best idea ever, hopefully they do it
I've got a hunch they will (if only for emirates)
@@cobyexplanes yh it would be a very smart idea, are they making a freighter?
Explain what?
The production of the 777-9 has been plagued with delays, including Covid which shut down factories for a time period, the FAA deciding it wanted to investigate how the FAA ITSELF was dealing with certifying planes, the production process itself had some issues, the engine they're using was delayed because of problems, etc.................. And the whole issue with the FFA stems from the 737 MAX having problems but was certified anyway but the plane has systems in it that should have required a different certification program vs. other 737s but it wasn't.
There are NO delivered 777-8s or 777-9s.
So, why are orders down? The large delays and airlines need planes NOW.
The 777X has been a series of unfortunate events, part of which isn't the problem of the plane itself but instead the FAA causing a lot of delays and the issue with the engine.
WHEN it gets certified AND Boeing ramps up production it will sell FINE because that plane is IDEAL for different routes. But once again airlines need planes NOW, so some have canceled orders to buy planes that can actually be manufactured NOW, minus of course the backup because of orders outpace production, and there is no other Boeing plane that can come close to what the 777 does so that means buying from Airbus. And this isn't because airlines feel the Airbus model they're buying is a better solution because most of the time it's not, but it's an acceptable solution giving the situation right now with the delays for the 777X. If an airliner for instance has mostly 777s already it would have been best to replace it with the 777X. The 777-300ER was a VERY successful plane and should have been mostly replaced with the 777-9 but they aren't delivering yet.
And for people who fail to understand why an airline will often want to stick with a certain type, it's because of pilot training. It's easier for an airline to have the pilots it needs if you have minimal aircraft types, because a pilot has to train on whatever type they fly and an airline would rather not bounce a pilot between flying different types, so once a pilot is certified on a type they tend to fly that type for a long time.
Also, these are LONG RANGE aircraft. They are used for LONG flights. You can THINK that an airline can get many years out of these but that's rarely the case. You get to the point of needing a major overhaul at some point and most airlines would rather buy a new plane rather than spend the money for that overhaul. It's expensive.
I would argue that the -8 is a nice, larger replacement for the -200LR. I could carry as many passengers (or more) than the A350-1000, much more cargo and have far less weight restrictions. I agree the future of this variant hangs on the success of ultra-longhauls.
The reason Boeing are not building the -8 is quite simple. The A350-1000 does its exact job and comes in some 26 TONNES lighter. That means it is technically obsolete as a design.
@@nathd1748how is it obsolete if the - 8 carries more payload and passengers than the 1000 with a comparable range and fuel burn AND better thrust to weight ratio lol? Weight isn't everything in a plane
@valet2972 It does not have comparable fuel burn. It requires 2x 110k output engines to do the job that the A350-1000 does with 2x 97k output engines. It is carrying about 26 TONNES of extra weight to do an almost on par job as the Airbus. You reckon lugging 26 extra tonnes is cost effective???
@@nathd1748 it does have a comparable fuel burn lol. Also it doesn’t need more powerful engines to do the job of the -1000, it has them to give it a higher thrust to weight ratio and carry more payload lol.
@valet2972 you can 'lol' all you like. The 777-8F has a 113T revenue payload. The A350-1000 had a MTOW bump in October 2023 to 322T giving the A350F a revenue payload of....113T!!!! The GE9X is currently not giving the fuel burn that they offered customers. Currently it is 1% over the XWB97 at a similar thrust output. So if the A350F is carrying 113T revenue payload but burning 6.2T average per hour over a given distance while the GE9x has to lug an extra 26T of body structure and burn 7.2T per hour to lug that same payload, then the 777-8F is going to be burning a TONNE of fuel per HOUR to shift the same load. If you cannot work out that the 777-8F is obsolete off those simple maths, then you are a FOOL.
In terms of range It was already beaten by A350-1000 on Qantas SYD-LHR contest which would be longest comercial flight.
boeing decided to not use al-li for the SLS main tanks, even though they were used on the space shuttle external tank which the SLS core is based on.
There seems to also be the factor of if you’re going to buy a 777X, then why wouldn’t you just go with the -9, why constrain yourself with the smaller -8 that doesn’t really offer much advantage over the -9.
My last 777 flight was American Airlines Rio de Janeiro to New York. The plane felt so futuristic that it reminded me of the movie 2001. I really loved the experience.
lol, try flying an airbus. your mind will be blown
@@vincevanderperre8660 I have flown the 380 from New York to Singapore. Excellent experience though I found issue with the engineering. I think on Airbus smaller aircraft the fly by wire system can feel jerky.
By far the most expensive part of an aircraft family is the manufacturing infrastructure and logistics networks. Since Boeing already has it, they would be foolish to abandon all the tooling and supply networks they set up. The air freight industry has been booming at a ridiculous rate and they can just focus on 777 freighters.
I think that the 777-8 will sell if Boeing start to use the AlLi alloy, this will lower the overall weight of the airframe, allowing the plane to fly at higher altitudes and reduce fuel burn. I would also say that the 777-8 could be a good replacement for the -200ER because of crew familiarization and the wider cabin giving airlines more space to be more innovative with their onboard products.
I beg differ, a little. If they switch to AlLi alloy for any version of 777-8, I think they should do the same for later 777-9 productions.
I think Boeing 777-9 has a fine balance of capacity and range, but underpowered at the same time. I expect Boeing will do the 777-9ER anytime soon.
@@talesfromunderthemoon The only issue with changing the 777-9 to al-li right now is that the 777-9 is already 5 years delayed and airlines like Emirates and Lufthansa will have a cow if it were to be delayed any further. The 777X would likely have to restart the certification process which would push back deliveries by years not months.
At this point it's probably too late to switch to AlLi
@@cobyexplanes Airbus launched a modernized NPS version of the A350 last year so I see no reason why Boeing can't do the same. It will be expensive in the short term but the potential fuel savings may make the 777X more efficient than the A350 and net them more sales in the long term.
The larger span of the 777X and the much more efficient GE9X engines are the dominant parameters here.
The troubled surface roughness of the AB 350 fuselage is detrimental to the efficiency.
As they say: If Boeing would be run by engineers, competition would be a long way behind.....
The GE9X will be rated at 110k lb. On ground testing it maxed out at 134.3 k lb. The GE90 now in service is rated at 115k lb. So in standard service the GE9X won’t be the most powerful engine flying.
The B777-8 will enter service after the B777-8F. This was discussed in the press over a year ago.
Always a good day when Coby posts a new video!
Thanks ◡̈
Nope he hates Boeing that’s why he is not uploading bad aircrafts from airbus he’s just an idiot
Al-Li alloys became famous in the 'sixties when it was used to save weight on fighters, mainly in undercarriage components. Thing were fine until it rained, and the undercarriage collapsed.
AL-Li is a bad idea. I remember years ago working for a company that was thinking about switching their skins to it. It turns out, it is much more brittle and the damage tolerance tradeoff isn't worth it. It is a nice science project, but it doesn't seem like it is truly a viable alternative.
I think one problem is that 787-9 and 787-10, not to mention 350-900, are quite adequate replacements for the 777-200ER.
Probably true
Biggest problem with the 777-8 is they're not certified and ready for delivery. 😶 I can't/don't even want to mention other production issues.
Present day you are right on the money my friend
It's the same issue they had with the 777-200LR. They are doing the same thing here and turning it to the F version which in the has sold sold well so far in a short amount time. They have already said some months ago the F is first and the passenger is on hold. Boeing is not committed to building the 8 passenger version and said as much a couple of years go. Where you right it's simply too heavy. That's nothing unusual in the industry. We've seen it from both Airbus and Boeing in the 350-800, 330-8 NEO and earlier with Boeing with the 767-200 etc etc. We've also seen it with the 380 with too much built in wait to support a larger version there was no market for. This isn't anything new.
Also do note that the 777-9 can also replace the -300er
IIRC, Aluminum-Lithium alloys have a non-orthogonal fracture mode. Installing bolts into interference fit holes exposed this issue on the first prototypes. Fortunately, long before the first flight. And all parts using Aluminum-Lithium alloys, including secondary non-structural parts were redesigned to use conventional aluminum alloys.
I think they will be happy with the program overall if the sales of the -8F and the -9P are strong enough. It doesn't cost THAT much more to validate the design of the -8 in the grand scheme of the overall program. If they make a -10 and it is successful as well, even better.
I'm sure Boeing is more concerned with the overall 777X program. They need to get the delays under control and get the program in the air making money for airlines. If they can make it work, the -8P poor sales won't really matter.
They are going to be what... 5 years late? That has cost them billions and makes them look amateur next to the time it took Airbus to get the A350 approved. Just one of the delay charges was $6.3 billion, and there was at least one more of $1.2 billion in that year. I believe their original development budget was $5 billion. So once again they've blown their development costs by more than 100%. I haven't see a complete accounting for Boeing's charges for amateur engineering mistakes recently. The MAX debacle cost them way over $10B and the 787 program was $24 billion over the $10 billion budget by the time it was approved.
@@cageordie I can't tell if/ how you are rebutting any points I made.
for me the 777-8 is at the same situation with 777-200LR and A330-800. have less seats but very long range flights so it's not suitable with most airliners, some use a smaller aircraft like 787-10 or A330-900, may have less seats but more efficient than 777-8, maybe will have a future orders most likely will BBJ, some privet airlines need long range aircraft but not oversized like 777-9, or if have very bad luck end up like what happened with 767-400ER
Exactly. They are behind with all their latest designs. Didn’t use new techniques or materials… Boeing is a mess.
The only thing they can focus on, is on a completely new designed aircraft that flies ways faster, while not using more fuel (efficiency).
Like a big Concorde that isn’t drinking fuel like a thirsty lion.
This way they will be on top again
It’s time for actual new generation aircraft. All current next gen planes are basically the same thing… with more efficient engines and lighter materials.
I couldn't agree more. The 777-200LR had much more range potential than the 777-300ER. Apparently the airlines decided that more seats trumped longer range. I expect that the final best seller of the 777X series is a -9 with longer range. Why would anyone chose the 777X over the A350? With the 777 you get GE engines.
High temperatures make it harder to generate lift, but low humidity makes it easier.
It has one this going for it that has traditionally been an Airbus selling point: commonality. Operators of other 777 variants will save on operating and training costs by choosing it over the A350-1000 even if the latter is abetter optimised aircraft for its payload in absolute terms. Non-ideal variants of other aircraft have sold in certain quantities for the same reason; operators of A320-family aircraft have bought A318s instead of the biggest CRJs in the around 100 seat market because of the streamlined operations that allows, even though the A318 is ludicrously over-winged and over-engined. Some A320 operators are however now coming round to the A220 now because of that (AF is replacing A318s with A220s)...
With that range and lift it could stand to be a good contender for military applications.
The a380 plus was crazy and no one really went in depth with that so it’d be pretty interesting to hear about
The whole aviation model changed it is more point to point rather than connecting to huge hubs between which the a380 makes sense ...
Better aircraft are available from Airbus. Choose which variant of the A.350 Best suits your routes.
More reliable yes
The original A330-300 didn’t sell shit either, then Airbus released the shortened -200 which was doing pretty well and then the market changed and everybody and it’s grandma all of a sudden wanted a -300.
Don’t write off the -8 just yet.
They have built a modern day VC10, a plane that had considerable better hot and high performance over the 707/DC8 but at the expense of a higher operating cost.
I would like to see if FedEx eventualy orders the -8F, which may be helped with the announcement of the MD-11 retirements. I would like to make this a series.
Without question the A350 is the most advanced airliner in the world. Everything from its maintenance on board computers, reliable components and sheer range and efficiency thanks to Rolls Royce pulling that out of the hat, clearly has Boeing trailing in its wake.
Does the 777-8 have the potential to replace the 757? One application would be to replace the 757s that are used for the U.S. President and Vice President to fly into smaller airports with shorter runways. If it can replace the 757 (with comparable engine thrust and lift), despite it being a wide-body, couldn't that open up a possible market? I feel as though I am unintentionally missing a big piece of my overall thoughts here.
I'd think the 737 Max 10 would be a better replacement for the Boeing C-32 (USAF POTUS transport based on the 757) It's almost as big and has the same range with the same passenger capacity. The other way to go would be a 787-8, even though the 787 is twice the weight of the 757 and has MUCH longer range).
Why ?
Because one of these costs over $500m+ a piece.
That’s before you even put an interior or livery on the outside, Not many airlines can afford let alone justify the stupendous price for a 777-8.
For an airline to make back that cost it would have to sell out all tickets with average picket price of $2500. Over 14months before ebitda.
It's about time World looked for another supplier simply because Boing crash history is gutting worst.
Small correction to make - while the GE9X engine on the new 777s is larger, it is actually slightly less powerful than the GE90 engines used on current 777s.
The GE9X bested the maximum thrust record of the GE90-115b. The nominal rating is lower (105k vs 115k) because the aerodynamics of the new 777X doesn't require that much thrust.
@@trackrat62 The stress test is irrelevant to the rated limits of each engine. The GE90 is rated higher like you said. The GE9X is not rated lower because of the aerodynamics, that's a silly reason. The GE9X is rated lower because it's more fuel efficient to make tradeoffs of power it doesn't need with regards to compression and fuel ratios and blade design. Regardless, it is a less powerful design than the GE90 like I said.
You should cover engines. What is going on with all the PW geared fan failures?
A-380 had the same type of problem. It was the baseline model, with bigger engines & wing than what was needed for that fuselage. There was supposed to be a new, bigger model to expand into the wing & engines but the twin jets killed it.
Ddi't the A380 suffer from the same problem? The wingbox and wing were designed for a longer fuselage, but only the shortest version was ever ordered and built, so it got stuck looking like a chubby boi.
Boeing built the C-17 which has a lithium aluminum body with a composite tail, it was a cost/time saving to keep the777 body close to the original 777.
I imagine it would be a significant engineering cost to re-develop the fuselage of the 777-8, but wouldn’t a narrower yet longer fuselage accommodate a similar, or slightly lower, passenger count while measurably improving the plane’s aerodynamics and flight efficiency?
This would lterally mean a new model. If they were trying to do that, a much easier way would be to try to stretch the barrower fuselage that Boeing already has AND is much more modern to create 787-11.
Air new zealand coukd use the 777-8. Their akl-jfk flight is really stretching the linit of the 787-9 - several trips have had to be diverted because of headwinds. Also they plan to replace their 777-300 with 787-10 which have smaller capacity and way shorter range.
Great video as always Coby!
