Flew on the ULR in business in January from Newark to Singapore then returned Singapore to JFK a month later. We had good tail winds so each flight only took 17 hours. I travel internationally a lot and this was by far my favorite plane and airline! It’s 3/4 business and 1/4 premium economy so only seats around 160 people.
Only is such a strange word there, even if we all understand... I was close to cabin fever with 15 hours (Doha to DFW, plus weather, plus diversion) in a Q-Suite, yet the Singapore Airlines to EWR is still a major bucket list item...
The reasoning of major achievements on the ULR version isn't technical major achievements, but rather how to keep passengers happy and not totally screwed up due to 15+ hours of flying. Airbus really doesn't recommend the ULR if the flight times are going to be less than 15 hours, and in those 15 -20 hours, you will literally be at the opposite side of the world, having gone through countless timezones. Unconfirmed - but a possibility, that due to very low number of take-offs and landings, versus a single aisle workhorses like the 737/320/321, there are plans to lower the cabin altitude - at the very least for the ULR version, which on average is expected to do anywhere between 1.1-1.4 takeoffs/landings per a 24 hour cycle between major maintenance programs at a MRO facility. The cabin altitude maybe around 4000ft, while A350's have a 6000ft cabin altitude.
I have flown this route to Singapore about 6 times now and will do so again in November. San Fransisco, Newark, and JFK have been the airports I have flow this plane. Honestly it is one of my favorite flights and the length is not an issue.
The extensive range of the a350 ulr has allowed Singapore Airlines to deploy this aircraft on ostensibly infeasible route between its hub and New York.
Very interesting, never knew about some of these changes. I thought it was just optimisation of the centre fuel tank area to make it bigger for the same space and this, hold more fuel. I never knew about the front cargo hold not being legally unuseable or smaller water tanks.
It’s an interesting video. I knew that some of the range enhancement was due to fewer passengers and extra fuel, but I didn’t appreciate how extensive these reductions were. We’re at the point where grams matter! I wonder what Boeing has cooking with its B789? United will take delivery of 4 to 6 aircraft later this year. Rumor has it that they will have extended range. We’ll will have to see the compromises with passengers and cargo that Boeing will have to make to achieve that goal. The aircraft has a very impressive range already. United Airlines was able to push the 787-9 beyond its limit of 8710 miles, when it flew from Los Angeles to Singapore. That flight was 8770 miles. United also sent an email to frequent flyers a few months ago asking them about changes to the front cabin, Polaris. Without saying so explicitly, it sounded as if United Airlines is planning something akin to a first class cabin on the new Boeing 789; when I say new, I mean a Boeing 789 with extended range. Certainly having more people in business and premium economy, so fewer in regular coach, reduces mass. Of course, it’s important not to forget cargo. I think cargo is going to be critical on these ultra long haul roots. Compromises can’t be made there. So, let’s wait for a few months, for the delivery of these enhanced Boeing 789s, to see if the company finally has some good luck.
Doesn't really change the big picture. A 789 HGW capable of SIN-LAX merely means it matches early 275t MTOW 359s, which SIA is deploying daily on the same route. Newer 359s have improved winglet and aerodynamics (which first featureed on 359ULR), MTOW up to 283t, plus 1t lower OEW since NPS. Which is hardly suprising if the rumored MTOW raised of 789 to 260t from 254t is true, but not really an issue either. 787's strong hold is being a reasonable all-rounded aircraft. A350's has unprecedented payload-range capability, but that comes with the cost of heavier aircraft and higher cost.
Would be interested in a follow up video on the route bejng flown by the a340-500, and a question as to when SN never operated the route with a 777-200LR
For anyone who is curious as to how the a350 ulr variant works, here is an explanation from my perspective: The main thing you need to know is planes have a weight limit, i.e. MTOW (Max TakeOff Weight) which they never should exceed in normal operations. Which means the total weight of Fuel + Passengers + Cargo must Never exceed the maximum operational weight of the aircraft, in this case 283,000 kgs (235,000kgs on the initial variants). However in standard flight configuration and routes flown, the a350 never had the need to fill their tanks to their full capacity, as they can save on fuel by decreasing weight, and either carry more passengers or more cargo, which means the full capacity of the fuel tanks is never used, only upto 3/4th of the fuel tanks capacity is used, and the rest is used to carry passengers and max cargo in the standard configuration, with routes mostly flown in the range of 3-15 hours, which is very well within the capabilities of the a350 standard variant. Why did they design the fuel tank to have more capacity than it should? Because it is the part of the structure known as the wingbox, which is the part that connects the wings and fuselage of the aircraft and helps share the loads of lift experienced by the wings onto the fuselage without the wings ripping off the fuselage. This wingbox has empty space inside of it, and that space is what is used as fuel tanks for the aircraft, with all relevant piping and pumps fitted onto it. That is why the a350 fuel tank is designed the way it is with excess capacity. Now how do we utilise the unfilled volume of the fuel tank? You can do that by increasing the max takeoff weight of the aircraft. Sadly that is difficult, as increasing mtow will necessitate reinforced landing leg designs, which can also increase the weight of the landing gear, and except a few niche ULR routes, the excess range on the a350 is generally not required. Also these changes might need an heavy overhaul of the structure of the aircraft to withstand such heavy loads, which is expensive. Hence increasing mtow to allow max fuel capacity does not make financial sense for Airbus or for any other airlines which might not need that range and excess reinforcement. The next best thing would be to slightly increase the mtow (from 235 tons to 283 tons), like airbus did with its ulr variant, but limit passenger seating, as passengers are also weights aircraft need to carry if you take the average weight of a person to be 70kg, and disable the front cargo hold to limit the max cargo capacity of the plane to keep it within operational limits for aircraft certification, and add few more pumps for the additional fuel that will be carried now on the same tanks, and you get the ulr variant of the aircraft without significant design changes. In fact the only difference between the standard and ulr variant of a350 is the ulr trades passenger, cargo and water capacity for additional fuel (the 283 mtow is now standard across both variants of the a350), and paperwork for the certification of the variant to be operational within the regulations, which is why the a350 can be converted from the standard to the ulr variant and vice versa with just minimal changes to its operation, and some additional paperwork. Also since it is an ultra long haul niche route that passengers pay a premium for the non stop convenience, you can just add premium class seats and elevate their experience and charge more money, while still making the route profitable! I hope this helps you understand the way the ulr variant operates! Thanks for reading this long comment!
@@MC-wd4oi Thank you! I too had problems understanding the concept of carrying more fuel using existing tanks, until I started playing flight sim games, and realized how fuel, passenger capacity and cargo hold affect the operational requirements of aircraft!
You made a fantastic job, but forgot to highlight one crucial thing. A350-900ULR is burning the way more fuel than usual A350-900. Because it carries more fuel than usual A350, it weights much heavier. This is an axiom, the more fuel you carry the more fuel your engines are burning. This has been proven by B777-200LR which is also could fly up to 17000 km, but burned unlimited amount of fuel. That is why A350-900ULR and B777-200LR are so unpopular throughout airlines all over the World. While A350-1000 and B777-9 are gaining and gaining popularity, each of them has collected almost 500 orders.
In the video, there's a mention that 'the ULR version is not that impressive.' However, after reading this comment, I believe it's actually a very impressive and clever design. You have the flexibility to convert the plane between different variants without being locked into a single model. Aircraft certification is extremely costly, and I'm all for anything that leads to cheaper tickets.
@@rufatdursunov8862 Yes more fuel but less passengers, cargo and water; is not the weight about the same? And it gets lighter and lighter along the way.
I expect that has a lot to do with scheduling and irregularities in maintenance where one of the A350s and pilots rated for it happened to be more practically available due to specific circumstances at the time. Must feel special to catch a flight that is out of the ordinary like that.
The A350-900ULR becomes much less impressive, when you consider that the Boeing 777 200LR has been in operation for eons and is a much older design (aerodynamics, non carbon composite fuselage etc. ), without all of the compromises mentioned in this video, and can still come close to the range of the ULR!
the A350-900 ULR wide body jets in service with Singapore Airlines, could do with a more relaxed cabin seating configuration . . . considering the well being of paxs in a 18 hour long flight time, regardless of cabin class . . . 128 - 143 seats in a typical 2-class layout is more of a sound configuration on such excessively long haul flights (routes) . . . the A380-800 could fly such xtra long haul routes as well . . . featuring a cabin configuration of 283 - 368 seats in a typical 3-class layout . . . first business & premium economy . . .
6:12 But one point is that you had to switch the plane as customer unless you have the UL-version, and with other factors like transit und boarding the turn-around-time does not matter in this case. One plane, non-stop. No lost connection, no lost luggage and god knows for the passengers, and also one planes for airlines. One could argue: no turn-around at all (for the second plane because there in none needed)
I thought the A350-900 ULR came with some solid modifications, but... to be fair though, it's just a 900 with some slight tweaks to make the range work well. Not a huge surprise but, really not bad modifications.
Why would the A350 even need an XLR version? It's max. range already exceeds that of a 777 ER and is more than sufficient for pretty much every route there is.
the A350-900ULR had an increased fuel capacity in the Center Fuel Tank which meant the max take -off weight had to increase. Typical Airbus then puts this learning into future aircraft as Airbus always do. The Max Take-off weight is what dictates what Airbus and SIA can do. THIS IS A NORMAL AIRBUS AIRCRAFT DESIGN PHILOSIPHY AND COPIES A330.
I flew on one of these from SIN-SFO back when they used to fly them there a couple of years ago. It was a complete premium cabin and the flight was great. I wish these beauties still flew to sfo on the 2nd daily flight🥲.
As a retiree with plenty of time on my hands, long haul no longer has any interest for me. I like to get out at the stopovers & spend at least a day looking around. Paying you own airfare also means "Economy class" so a good night sleep in an airport hotel is a lot cheaper than a business class ticket .

@@user-yt198 "This was achieved by integrating a modified fuel system, which increases the aircraft’s fuel carrying capacity by 24,000 litres without the need for additional fuel tanks." - www.airbus.com/en/newsroom/news/2018-09-ultra-long-range-a350-xwb-goes-the-distance
@@devanarayananj1291only the a321xlr has the auxillary fuel tanks, and additional reinforcements to aircraft underbelly structure to prevent fires in case of a belly landing. The a350 ulr just uses the remaining unused volume in its fuel tanks.
The single biggest factor in fuel burn is MAX ZERO FUEL WEIGHT. BY eliminating the fowzrd cargo hold that cost is shifted elsewhere, but it places airframe in a tail attitude that limits the need for trim giving the distence it needs. This is just a prestigious marker for Singapore, the flight is heavily subsidized
The 777-300 ER has far better economic performance passenger and freight services. The 777x with larger fuel tank would match or better the 350ulr range, freight and economics per seat Anyone not planning to purchase that will no longer be competitive
Just a thought for any nervous travelers who may watch your excellent videos - given certain recent events, calling the video "DEEP DIVE" may not be entirely appropriate 😂🤣
It is interesting though that Qantas chose the stretched A350-1000 rather than the 900ULR for its forthcoming Sydney-London flights (slightly longer than Singapore-New York). With a reduced passenger count the -1000 can make the distance while still carrying more people than the -900ULR. It suggests the ULR variant was not needed and so an expensive mistake.
The short Answer = carry less passenger and add more fuel tank...... DUH... any airplane can do that if they wanted to.. a Cessena 172 can fly from Ca to Hi over 20+ hours so WHOOPY DO...
Exactly I respect Airbus, I love working on their aircraft everyday but let’s be real, they are basically turning their aircraft into a flying gas tank, especially the 321XLR
The commonality with normal 359 is a good news for SW in case they need to reconfigure the airplane back to normal or recertify as XLR. Where else can SQ take advantage of this aircraft range to? If SQ have big business in Brazil, SIN to GRU is within the massive range too!

What is ULR? What are the differences between it and the -1000 or XWB?
ULR means Ultra Long Range and it is a modiefied -900. XWB is just a marketing name. Everey A350 is a XWB, just like every 787 is a Dreamliner

I assume you're on the older side? If so, I'm not sure whether I'd look at is as having plenty of time on your hands. Make the most of it.
@@somealias-zs1bw Good one, made me laugh. One day at a stopover isn't going to make much difference
I still don't get how it carries more fuel with the same tanks.
Actually they do have auxiliary tanks inside the cargo compartment
The same applies to 320 xlr
-Video is completely wrong. Cargo volume capacity is reduced for a reason. Extra fuel tanks. How is it possible to store extra 20 tons of fuel?-
This too has always confused me, until I started to play flight sim games.
The main thing you need to know is planes have a weight limit, i.e. MTOW (Max TakeOff Weight) which they never should exceed in normal operations. Which means the total weight of Fuel + Passengers + Cargo must Never exceed the maximum operational weight of the aircraft, in this case 283,000 kgs (235,000kgs on the initial variants). However in standard flight configuration and routes flown, the a350 never had the need to fill their tanks to their full capacity, as they can save on fuel by decreasing weight, and either carry more passengers or more cargo, which means the full capacity of the fuel tanks is never used, only upto 3/4th of the fuel tanks capacity is used, and the rest is used to carry passengers and maximum cargo in the standard configuration, with routes mostly flown in the range of 3-15 hours, which is very well within the capabilities of the a350 standard variant.
Why did they design the fuel tank to have more capacity than it should? Because it is the part of the structure known as the wingbox, which is the part that connects the wings and fuselage of the aircraft and helps share the loads of lift experienced by the wings onto the fuselage without the wings ripping off the fuselage. This wingbox has empty space inside of it, and that space is what is used as fuel tanks for the aircraft, with all relevant piping and pumps fitted onto it. That is why the a350 fuel tank is designed the way it is with excess capacity.
Now how do we utilise the unfilled volume of the fuel tank? You can do that by increasing the max takeoff weight of the aircraft. Sadly that is difficult, as increasing mtow will necessitate reinforced landing leg designs, which can also increase the weight of the landing gear, and except a few niche ULR routes, the excess range on the a350 is generally not required. Also these changes might need an heavy overhaul of the structure of the aircraft to withstand such heavy loads, which is expensive. Hence increasing mtow to allow max fuel capacity does not make financial sense for Airbus or for any other airlines which might not need that range and excess reinforcement.
The next best thing would be to slightly increase the mtow (from 235 tons to 283 tons), like airbus did with its ulr variant, but limit passenger seating, as passengers are also weights aircraft need to carry if you take the average weight of a person to be 70kg, and disable the front cargo hold to limit the max cargo capacity of the plane to keep it within operational limits for aircraft certification, and add few more pumps for the additional fuel that will be carried now on the same tanks, and you get the ulr variant of the aircraft without significant design changes.
In fact the only difference between the standard and ulr variant of a350 is the ulr trades passenger, cargo and water capacity for additional fuel (the 283 mtow is now standard across both variants of the a350), and paperwork for the certification of the variant to be operational within the regulations, which is why the a350 can be converted from the standard to the ulr variant and vice versa with just minimal changes to its operation, and some additional paperwork. Also since it is an ultra long haul niche route that passengers pay a premium for the non stop convenience, you can just add premium class seats and elevate their experience and charge more money, while still making the route profitable!
I hope this helps you understand the way the ulr variant operates! Thanks for reading this long comment!

@@devanarayananj1291only the a321xlr has the auxillary fuel tanks, and additional reinforcements to aircraft underbelly structure to prevent fires in case of a belly landing. The a350 ulr just uses the remaining unused volume in its fuel tanks.
the range is impressive but a trade off- 160 passengers, no cargo , lower water et al. How does this compare with 777-8 From Boeing if it comes...
I thought it had the A350-1000s fuel delivery system? correct me if im wrong
More precise to say the -1000 has the ULR's fuel system. The -1000 arrived after the ULR.
@@kenoliver8913 Ahhh ic. thx for the insight it never crossed my mind that it was the other way around XD
one beautiful aircraft
The single biggest factor in fuel burn is MAX ZERO FUEL WEIGHT. BY eliminating the fowzrd cargo hold that cost is shifted elsewhere, but it places airframe in a tail attitude that limits the need for trim giving the distence it needs. This is just a prestigious marker for Singapore, the flight is heavily subsidized
The a350ulr also does not have brakes coolers on their wheels unlike the regular a350's
The regular a350s don’t have brake fans.
Fascinating🤓
Cool stuff ig
The 777-300 ER has far better economic performance passenger and freight services.
The 777x with larger fuel tank would match or better the 350ulr range, freight and economics per seat
Anyone not planning to purchase that will no longer be competitive
Just a thought for any nervous travelers who may watch your excellent videos - given certain recent events, calling the video "DEEP DIVE" may not be entirely appropriate 😂🤣
It is interesting though that Qantas chose the stretched A350-1000 rather than the 900ULR for its forthcoming Sydney-London flights (slightly longer than Singapore-New York). With a reduced passenger count the -1000 can make the distance while still carrying more people than the -900ULR. It suggests the ULR variant was not needed and so an expensive mistake.
I wonder what the profitability is like given the loss of so much freight capacity.
@@grahambaker6664 the aircraft is actually profitable because of the premium layout
It only has premium economy and business class seats.
It's a case of balancing priorities and the different sources of income on your particular route network.
A bit pointless bringing this video out days AFTER the much more impressive XLR was certified.
Why didn't qantas order this variant?
The short Answer = carry less passenger and add more fuel tank...... DUH... any airplane can do that if they wanted to.. a Cessena 172 can fly from Ca to Hi over 20+ hours so WHOOPY DO...
Exactly
I respect Airbus, I love working on their aircraft everyday but let’s be real, they are basically turning their aircraft into a flying gas tank, especially the 321XLR
a350-1000ulr when?
So how often are passengers running out of water?
Do they start rationing water very tightly when its levels get low?
They can recycle it and give passengers the ISS experience 😂
It has less passengers so no need for that much water
@tuuchen2990 But it should be about passengerHours not passengers.
@@suserman7775 maybe everyone is asleep for half the flight
They don’t have economy rather 80+ premium economy seats in 2-4-2.
Shows how versatile the A350 is. (satire)
same aircraft for project sunrise?
Kinda, they’re going for the -1000
The commonality with normal 359 is a good news for SW in case they need to reconfigure the airplane back to normal or recertify as XLR.
Where else can SQ take advantage of this aircraft range to? If SQ have big business in Brazil, SIN to GRU is within the massive range too!
can I get one of these in a goodie bag?
Less passengers means higher ticket prices... How much so?
There are no “regular” Economy seats. The lowest fare category is Premium Economy seats, so passengers are paying more per seat.
Whatever you say or imply the A350 ULR is better than the Boring aircrafts in the same category.
What's the name of the BGM playing the first half of the video?
What a ruse ! Just reduce the cargo and you will get the extended range. LOL
Just stop the lame US gallons and stuff.... Nobody cares about that US stuff.
Potable is pronounced in pot-able.

Nope, at least in British English it is pote-able.
