Piccolo estratto dell'analisi di Flightglobal sull'uso che stanno facendo le compagnie aeree dei loro Dreamliner.

Henk Ombelet from Flightglobal's consultancy service Ascend tracks how airlines are deploying the Boeing 787 aircraft, four and a half years into its operating life.


Since its entry into service with All Nippon Airways in late 2011, airlines have clocked more than 100,000 revenue flights with Boeing 787 aircraft.


Data from Flightglobal's schedules specialist Innovata shows that now 35 scheduled carriers are operating a combined totaled of 375 Dreamliners. These are deployed across some 368 intercontinental routes.


A quarter of these are new routes - or least new to the airline which has taken the 787. The majority of these routes are operated by Norwegian, which used the type to begin long-haul services - albeit it started some routes using leased older models because of the delays in 787 deliveries.


Another fast-expanding carrier, Qatar Airways, is among three other airlines to use their 787s to launch five or more new routes. The other two are Air India and United Airlines.


By contrast 15 Dreamliner operators are still to deploy the type on any new routes - instead using their 787s either to replace or augment other widebodies on existing routes.


While these 15 airlines account for almost half the number of 787 operators, they operate only 73 aircraft between them - less than a fifth of the in-service fleet. These airlines have largely only taken delivery of the aircraft in the last couple of years, and suggests 787 customers' priority is to enhance service or efficiencies on existing flights before looking to break new ground with their 787s.


None has waited longer than Ethiopian Airways - nearly four years before opening it first new route with the type. By contrast 13 operators used 787s to open new routes almost immediately.


Efficencies was one of the key selling points of the 787s, albeit in what was initially a much harsher high oil-price environment. Dreamliner operator have been quick to use the type to enhance existing routes. Airlines have use the aircraft to replace existing aircraft on 140 of the 368 routes the aircraft is deployed on. Most of these were operated by 777, 767 and A330


It has also allowed airlines like Virgin Atlantic and Etihad to reduce their A340 fleet, while Hainan Airlines, LAN Airlines and Royal Jordanian have got rid of them altogether. The 787 is more economical (in terms of direct operating costs) to operate than the A340, even in the current fuel price environment.


On the remaining 130 routes the 787 is used alongside other aircraft types.
 
Analisi interessante. Forse la selling proposition del 787 si sta dimostrando reale.
 
When US manufacturer Boeing first introduced the Boeing 787 Dreamliner it was marketed as a hub-buster, an aircraft that would enable airlines to fly non-stop point-to-point services between non-hub airports. Now after almost five years of airline service, data does not seem to necessary back up the initial views with only one in four current Dreamliner routes classified as a new air service.

When US manufacturer Boeing first introduced the Boeing 787 Dreamliner it was marketed as a hub-buster, an aircraft that would enable airlines to fly non-stop point-to-point services between non-hub airports. This was partly a counter argument to its rival Airbus that was putting its efforts into promoting the A380 SuperJumbo, an aircraft perfect for flying high density routes, quite often to, from or even between major hubs.
Now after almost five years of airline service, data does not seem to necessary back up the initial views with only one in four current Dreamliner routes classified as a new air service. In a fascinating presentation during the Routes Europe Strategy Summit in Kraków, Poland, Henk Ombelet, a senior analyst at the Ascend Flightglobal Consultancy said: “There are arguments for and against whether you can genuinely call the 787 a hub buster.”
“It will allow some more hub to smaller point flying than perhaps was possible before, or perhaps earlier than before because the market size required to make a route profitable has reduced. But my view is that while undoubtedly a capable aircraft, on its own it is not going to change the long-haul business model of the airline industry. It is a step change, with lower costs and potentially more comfort for the passenger depending on how the airline kits it out, but it is not a revolution.”
What is sure, although not necessarily a hub-buster, the Dreamliner has helped airlines enhance their passenger offer with improved economics and efficiencies also helping their bottom line. The type has also allowed many older less efficient aircraft to be retired from commercial service.
Less than five years since Japanese carrier All Nippon Airways (ANA) inaugurated the 787 into passenger service the development of the route network served by the 787 has been quite staggering, as you can see from the following slide from the presentation.

“There are now 37 airlines with the aircraft, operating over 600 routes across all the world using the aircraft. The current backlog is around 750 aircraft, and there are another 300 options to be firmed in the future,” said Ombelet.
By the end of this year that operator count will surpass the 40 airline milestone which will collectively offer around 300,000 flights a year with the aircraft. “Schedule data shows that the growth in the number of routes is stalling a little, but as the aircraft is put to more use, operating on longer sectors than before and with most airlines no longer needing to operate short-haul sectors to familiarise themselves with the aircraft, the ASK growth is accelerating and is growing faster than the number of flights,” explained Ombelet.

The analyst revealed that schedule data for 2016 shows that out of more than 600 routes, there are 368 long-haul routes that are operated on the 787 in 2016 of which 90 can be classified as new routes (not served by the airline for previous five years), including ten that are scheduled to start later this year.
Around a third of these new routes are operated by low-cost, long-haul airline Norwegian, a growth that certainly would not have occurred in its current timescale without the arrival of the Dreamliner. Interestingly though around half of the 35 airlines using the aircraft on intercontinental routes, only 19 have actually started new routes with the type, albeit many of the others are relatively new operators of the type.
One example is Ethiopian Airlines, says Ombelet, which despite operating the 787 for four years will only inaugurate a new route with the type this year when it inaugurates flights between Addis Ababa and Newark.
“On average so far it takes around 16 months between first delivery and new route,” the analyst explained, but this average is coming down as airlines, airports and maintenance providers are more familiar with the aircraft, posing fewer problems in opening new routes.
upload-18204-standard-940x626.jpg

The 787 was designed especially for long thin routes and the data presented by Ascend shows that the new long-haul routes that the aircraft is deployed upon do tend to be a bit longer than existing routes and also tend to be lower frequency. However, rather than a hub-buster, almost all of the routes it serves currently are operating from at least one hub airport.
“Only four so called spoke-to-spoke services were identified based on current schedules,” explained Ombelet. These were identified as Hainan Airlines’ flights on Shanghai – Boston and Changsha – Los Angeles and Jetstar Airways flights on Brisbane – Denpasar and Gold Coast – Wuhan.
“Norwegian is in a class of its own, and is really a point-to-point operator, so in a way its 33 routes can also be classified as spoke services despite many serving hub airports,” added Ombelet. However, he noted that the low-cost carrier is developing into a hub-and spoke operator by offering through ticketing options via its short-haul network into the four airports it currently serves long-haul from Europe.
In some respects it is no real surprise that the 787 is still serving hub airports, after all that’s almost inevitable for regulatory as well as economic and operational reasons. Ombelet also identified that there are examples of the aircraft flying hub-to-hub and gaining feed at each end of the route: Japan Airlines uses the aircraft to fly from Tokyo to Helsinki, the latter a hub of its alliance partner Finnair.
upload-18205-standard-940x626.jpg

But it actually appears that the majority of 787 flights are actually currently hub-to-spoke services. “The new flights from British Airways and All Nippon Airways to San Jose, California are good examples of this,” explained Ombelet. “These clearly bypass other US hubs both these airlines currently serve. It gives passengers the option of a more convenient direct service into the San Jose area, which has a substantial catchment area of its own”.
While not a hub-buster, the 787 has certainly enabled airlines to launch flights into markets that have matured enough to support a direct service and at least bypass the hub on one end of the route, while still retaining some feed at the other, further reducing the risk on the route. It has even helped grow markets that have subsequently been expanded with larger aircraft, namely British Airways on London – Austin and Qatar Airways on Doha – Amsterdam, where 777s have now replaced 787s.
Ombelet believes that the 787 has not lived up to its initial marketing messages as most long-haul markets are still too small and fragmented to warrant direct services, while flying widebody equipment, however efficient, still generates significant costs to an airline.
“The long-haul airline business model isn’t going to change because of the 787, or indeed the A350, anytime soon,” observed the analyst. However, he noted that on medium-haul routes such as shorter Transatlantic markets still served by 757 equipment there is the potential that new short-haul offers such as the A321neo and potential Boeing Middle of the Market Aircraft (MOMA) could extend the low-cost carrier point-to-point model to a longer, intercontinental range. But, that is another story!
 
La metto qui per non aprire un altro thread e non riesco a trovare il precedente thread in cui se ne parlava. Parrebbe che i problemi del Trent 1000, con numerosi aerei - vedi Virgin, o il povero G-ZBJE, senza motori ormai da mesi - a terra, peggioreranno. Le revisioni dovranno continuare, pare anche per i motori già revisionati, e ci sono voci su una riduzione dell'ETOPS.

Rolls-Royce and airlines grapple with further Dreamliner engine issues

LONDON (Reuters) - Rolls-Royce (RR.L) requires more money and more inspections to fix problems with Trent 1000 engines on Boeing (BA.N) 787 Dreamliner planes, leading to further disruption for airlines and testing relations between Rolls and its customers.

Problems with engine turbine blades wearing out sooner than expected have hampered a restructuring program prompted by the engineering company’s declining older engine program and plunging demand for oil equipment.

It said on Friday that more regular inspections are required and would lead “to higher than previously guided cash costs being incurred during 2018”.

“We sincerely regret the disruption this will cause to our customers,” CEO Warren East said in a statement.

Airlines have already been forced to alter schedules or lease other aircraft, but the latest issues could be more far-reaching.

The U.S. Federal Aviation Administration (FAA) plans to reduce the amount of time the affected planes can fly on a single engine after a failure of the other. The time limit would drop as low as 140 minutes, compared with the current window of 330 minutes, a source familiar with the plans said.

This effectively curtails operations across oceans or remote areas.

The European Aviation Safety Agency (EASA) will also order increased inspections of affected engines in line with actions outlined by Rolls-Royce. Currently inspections must be carried out after every 200 flight cycles.


The two advisories are due to be issued on Friday, the source said.

Rolls said it would reprioritize spending to mitigate the costs and kept its 2018 free cash flow guidance unchanged at about 450 million pounds ($643 million), give or take 100 million pounds.

Shares in Rolls, one of the biggest names in British manufacturing, were down 1.3 percent by 1251 GMT.

It announced the need for stepped up inspections after liaising with authorities over a separate issue with the compressor on Trent 1000 Package C series engines. Rolls said there were 380 such engines in service.

Boeing said that about 25 percent of the Dreamliners flying were powered by the engine and it was deploying support teams to help to manage service disruptions.

Mi chiedo se questo comporti problemi con le vendite ad Airbus che mi pare offra solo RR su 330neo e A350.

Credo si tratti del Trent 1000. Il 350 è motorizzato Trent XWB ed il 330 neo col Trent 7000.
I problemi del Trent 1000 sono superati con la versione 1000 TEN.
I grounding sono dovuti all'indisponibilità di motori sul mercato ed alla revisioni di quelli in servizio che prende tempo.

Naturalmente i motori sono diversi, ma la reputazione di RR sta un po' soffrendo e questo potrebbe complicare leggermente le cose per Airbus che a RR ha legato il futuro prossimo dei propri WB.

Boeing to implement structural design change in 787-8 for production commonality


Boeing will implement a manufacturing shift later this year designed to bring the 787-8 into more conformity with the production of its larger siblings, the 787-9 and 787-10.

The move, involving the aft fuselage production, will reduce costs and increase commonality between the first family member and the two larger models.

[...]

The 787-8 lacks commonality with the 787-9 and 787-10. The latter are 95% common, making production easy and cost effective. The 787-8 is only roughly 30% common with the 787-9, Darrell Larson, director of aft-body operations at Boeing’s Charleston plant, acknowledged during a press briefing in advance of delivery of the first 787-10.
The lack of commonality complicates production and boosts costs on the 787-8 as it can’t benefit from learning on the 787-9 and -10 on the part that differs.

[..]

Breathing new life into the 787-8?
Does the investment mean Boeing is breathing new life into the 787-8, supporting sales of this model that had all but been abandoned?
It would seem so.
Given the aggressive war Boeing has engaged with Airbus to kill the A330-800, Boeing’s renewed interest in the 787-8 is apparent.
But the renewed interest may conflict with the potential New Midrange Aircraft, or NMA (aka 797). This two-member family concept is 220-270 passengers, a similar size to the 787-8/9, but with ranges of 5,000nm and 4,500nm respectively. The ranges for the 787-8 and -9 are more than 7,000nm and 8,000mm respectively.

Boeing publicly insists the NMA won’t cannibalize the 787-8, but it’s known to be a topic of debate internally at Boeing’s Longacres sales headquarters.
Furthermore, only 30% of the 787’s missions are more than 5,000nm, according to an LNC analysis. The mission and product overlap is obvious.

Da ignorante in materia chiedo lumi: com’è possibile che tra due versioni di una stessa macchina balli il 65% di commonality?
 
Era prevedibile. Il 788 aggiornato allo standard dei fratelli maggiori a livello di commonality, è un'ottima carta da giocare nei confronti del 330neo. Soprattutto presso le compagnie che hanno già in flotta i 789/781.
Da ignorante in materia chiedo lumi: com’è possibile che tra due versioni di una stessa macchina balli il 65% di commonality?
Probabilmente man mano che il progetto 788 avanzava, hanno scoperto tante possibili micro-ottimizzazioni, che però per essere implementate avrebbero richiesto tempo. E il 788 era già in ritardo di 2 anni.
Il 789 viceversa ha potuto giovarsi da subito delle esperienze maturate con il fratello minore, ma al prezzo di una ridotta commonality.
Da un certo punto di vista potremmo dire che il 788 è la versione Beta del 787, mentre 789 e 781 sono quelle definitive.

Il 788 è già uguale, per piloti ed equipaggi, al 9/10. La differenza sta negli standard produttivi e nella manutenzione, diciamo che è quello che ha subito di più la genesi travagliatissima del Dreamliner...
 
La botta dell'ETOPS si fa sentire. Il nuovo volo BA61/62 LHR-SEZ, dopo aver perso l'ETOPS a 180, ora ha un tempo di volo piu' lungo di 90 minuti in media, con un ritardo medio per la partenza del volo di ritorno di un'ora.
 
Metto qui. Da newsletter aziendale

The total bill for hundreds of malfunctioning Boeing 787 Dreamliner engines will top £1 billion for Rolls-Royce as it promised to accelerate its testing regime to get the afflicted planes back in the air, writes The Times. The article highlights that faults in the Trent 1000 engine, which was specially designed and built by Rolls for the Dreamliner, have grounded aircraft operated by British Airways, Virgin Atlantic and Norwegian, among others. It adds that the 'rising costs of the crisis' have led to a 'clampdown' on executive expenses, with a group with a ban on all non-essential travel, the shelving of some IT projects and a delay in other unspecified capital expenditure.

Qatar Airways looks at loaning wide-body jets to British Airways



  • Move would aid U.K. carrier as its 787s get emergency overhaul
  • Mideast group has surplus capacity following Saudi blockade

Qatar Airways is considering loaning planes including wide-body models to British Airways in a move that would soak up excess capacity at the Gulf carrier while easing fleet pressures at the U.K. operator as some of its own Boeing Co. 787 jets get emergency overhauls.

Qatar Air is evaluating the situation and could trim frequencies on some routes to free up aircraft for BA, whose parent IAG SA is 20 percent owned by the Mideast group, Chief Executive Officer Akbar Al Baker said in an interview.

While Qatar Air previously loaned Airbus SE A320 jets to British Airways after a Saudi-led blockade forced it to close some Gulf routes, the transfer currently under scrutiny would be the first involving long-haul planes. Al Baker has said his company suffered a significant loss in the year through March, partly as a result of westbound flights being diverted to avoid closed airspace.

“If we have to help them due to their current predicament we will do our best, even if it means reducing some frequencies from our current network,” Al Baker said in Cardiff Wednesday after Qatar Airways began flights to the Welsh city. The company doesn’t have spare aircraft as such but there are destinations where the timetable may be “excessive,” he added.

777X Delay

British Airways has taken delivery of 26 787s out of an order for 42, all powered by Rolls-Royce engines stricken by design flaws that are causing parts to deteriorate quicker than planned. Regulators have ordered extra shop visits for the model and put limits on its operating envelope.

Al Baker said Boeing’s new 777X aircraft, of which Qatar will be one of the first recipients, is currently running about two months behind schedule, while suggesting the model should still meet targets for its first flight and delivery.

“There’s a small slippage but I’m sure that it’s so small that they will catch up,” he said, adding that General Electric Co. has provided assurances that development of the plane’s engines is proceeding as planned.
Qatar Airways will back IAG if chief Willie Walsh decides to go ahead with a bid for Norwegian Air Shuttle ASA, Al Baker said, adding that he’s confident that will happen only after the London-based group has conducted very extensive due diligence. Qatar has no seat on IAG’s board and “doesn’t interfere” in its affairs, the CEO said. His airline won’t itself be investing in Norwegian, he said.
