The Boeing 777-8 is a bit of an enigma. When it takes to the skies later this year, it’ll become Boeing’s newest commercial offering. Naturally, it's chalk full of cutting edge innovations, and occupies a market segment that’s been red hot in recent years. But despite these favorable conditions, the plane can’t find any takers. It’s been a decade since the last passenger -8 was sold. And now, analysts are pondering whether Boeing might cancel the jet. So, what’s going on here? Why won’t anyone buy the 777-8? Let me explain…

[@dennisthebrony2022]

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.

[@Floor773]

I agree, however the -900 had more orders over its lifetime

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

I also want to point out that summers here in the Gulf are hot and VERY humid, rather than lacking humidity.

[@terrytt5067]

Yeah, I worked in Salalah, Oman. During the Monsoon it usually had 100% humidity

[@pilotluca_]

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

[@CerberusTenshi]

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.

[@alfredosauce1]

he must've meant high humidity. Anyone who has been to the Gulf knows its incredibly humid

[@luisdestefano6056]

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.

[@gtsguy4138]

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.

[@South34degrees]

@@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.

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.

[@foxlake6750]

Adding lithium to aluminum reduces density (wt.) and increases stiffness, but makes it very expensive and limits it use.

[@YHDiamond]

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.

[@nntflow7058]

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.

[@johndoh5182]

@@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.

[@oldchinahand1305]

In regard to poor selling aircraft: Could I trouble you to look outside the more recent Boeing/Airbus to historical aircraft such as the VC-10, Lockheed Tri-Star and other pre-90s aircraft? Airbus was formed out of a large number of smaller European manufacturers whom had several models with potential but each offers interesting lessons in terms as to why they needed to amalgamate to compete with the American giants.

[@geoff1201]

My understanding is that the VC10's problem was similar to the 777-8. It was specified to get between the UK and hot, high altitude, Commonwealth countries, which it did very well. The problem was that no-one else had the same requirements and so it didn't sell.

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.

[@larrydugan1441]

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.

[@jason12680]

Probably takeoff weight is a more important factor.

[@biopsiesbeanieboos55]

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.

[@jackpowell9276]

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.

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) :)

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.

[@ChrisCooper312]

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.

[@jankrusat2150]

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

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.

[@ohheyitskevinc]

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).

[@terryross1754]

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.

[@clarenceghammjr1326]

[@davidellis4031]

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.

[@spyrosg3172]

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.

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.

[@ARCHAEVS]

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.

[@w8stral]

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.

Thanks bro for the update. I wanted to shop for one but I won't. 😪

[@luisdestefano6056]

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.

[@cobyexplanes]

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

[@mmm0404]

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

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?

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.

[@markharrison5321]

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.

[@csk4j]

This is another great show! Can you discuss more in the future? The A350X versus the triple 7-9x? I still don't understand how the 777-9x can really compete with the A 350X. I understand that some airlines will get big discounts, and some airlines are concerned with fleet optimization. However, I don't understand relying on those elements to sell. What seems to be an inferior product. The 777x does have a slightly bigger cargo capacity but it also has a bigger price tag.

[@cobyexplanes]

Well, the 777-9 is bigger than both A350 variants, so it's kindof in a class of its own. At this point it probably doesn't make sense for Airbus to further stretch the A350 to compete w the -9 since there isn't a massive market

CF has a problem with rigidity as it is MUCH worse than aluminum. 787 fuselage CF... was just as heavy as if they had made it from aluminum and MORE expensive. My guess is 777X now also has 2G wind up turn load alleviation and why the fuselage is much lighter and allowed to be lengthened, interior wider and MORE than likely just about as light as CF... which brings up Al-Li.... should have been used and is probabally lighter than CF at this point until someone can figure out how to make Boron fibers cheaply.

Present day you are right on the money my friend

[@dylanstark2583]

@CobyExplanes could you make a video about why the 737 classic series had the shortest production run compared to the other three generations of the 737 family? The classic series just like the 777x family had significant performance improvements compared to the 737-100/200 but yet had short production runs.

At 2:45, you you have used the term 'gate'. What you should have said was 'stand'. A 'gate' is where people embark or disembark the aircraft to/from the terminal. A 'stand' is where an aircraft physically parks on the apron.

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?

[@clarenceghammjr1326]

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 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.

[@nathd1748]

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.

[@valet2972]

​​@@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

[@nathd1748]

@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???

[@valet2972]

@@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.

[@nathd1748]

@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.
