https://www.conklindd.com/CDALibrary/ACCostSummary.aspxScusate il semi-Ot: dove trovo i dati di costo orario per altri modelli? Grazie
Tieni presente che sono gratis solo i costi variabili, per avere anche quelli fissi bisogna pagare.
Bisogna capire a quando sono aggiornati questi dati, se sono calcolati con il prezzo del petrolio di un anno fa o attuale
Con il petrolio al 50% dai massimi i 18k USD potrebbero essere diventati 13 o 14k. In più il 77L dovrebbe essere più efficiente del 745 (magari portando il costo orario a 12k). E' possibile?
A quel punto spalmati sui 100 posti in configurazione all business fanno "solo" 3.700 USD per posto. Già più ragionevole.
A quanto pare SQ ed Airbus starebbero valutando una versione del 359 con MTOW maggiorato a 280t. Soluzione che sembra fattibile con poca spesa e che imho avrebbe anche il non trascurabile vantaggio di poter usare le macchine altrove con una redditività molto simile a quella del 359 standard, qualora le rotte USA non si dovessero rivelare proficue.
Airbus in talks with Singapore for ultra-long range airplane; “A350-900LR” likely
July 14, 2015 © Leeham Co. Singapore Airlines is in talks with Airbus and Boeing about an Ultra-Long Haul airplane that can fly from Singapore to the US non-stop.
The talks were first reported by Bloomberg News June 17, during the Paris Air Show.
Singapore discontinued the flights to Los Angeles and Newark when rising fuel prices made operation of the Airbus A340-500 used on the trips uneconomic.
Boeing currently has one airplane capable of service to Los Angeles, the current generation 777-200LR, which has a standard range of 8,665nm but not to Newark which is 9,020nm great-circle without the unpopular Additional Cargo-bay Tanks (ACT). Los Angeles is 7,560nm from Singapore and when flying west the extra range in the standard 777-200LR would be needed to combat the prevailing westerly winds on the mission.
The Airbus A350-900 has a range of 7,900nm when transporting the same 301 passengers as 777-200LR. Boeing’s forthcoming 777-8X has a planned range of 9,300nm but it’s entry-into-service isn’t planned until around 2022.
Singapore is a 777 Classic operator. It has 70 A350s on order. The 777LR, a generation behind the A350, is a much heavier and thirstier airplane. With the 777-8X at least seven years into the future, and with a large, existing order for the A350-900, Singapore’s only modern choice for an Ultra-Long Haul airplane would be an improved version of the A350-900.
Airbus could achieve the performance of a 777-200LR by increasing the Max Take-Off Weight of the A350-900 from 268t to 280t. This would allow an additional 12 tonnes of fuel to be tanked and according to our model this would extend the range with the passenger load of the 777-200LR to 8,600nm thereby equaling the payload-range performance of Boeing’s long ranger. It would consume 22% less fuel however, 100 tonnes instead of 130.
The increase of Max Take-Off Weight of A350-900 is possible as the extra weight is fuel and this goes into the wings, where it sits close to the lift, thereby causing a minimal increase of loads into the wing and fuselage of the A350. Airbus has seen that there are structural margins in the A350 design, so likely improvements would be constrained to local beefing up of things like brakes to achieve what we like to call an “A350-900LR.”
One other area Airbus would also be looking to change would be the tank size of A350-900. With its standard 138,000 liters it would be on the limit for a 8,600nm mission and with any cabin with less seats or lower load-factor than 100% the aircraft would be fuel limited. We would therefore assume Airbus would include the larger wing tank area from A350-1000 in a “A350-900LR” design. With its 156,000 liters it would give plenty of room for the necessary fuel for Singapore Airlines long range US missions.
Given the launch this year of the A321LR, we think it likely Airbus is preparing to launch an “A350-900LR” version of A350-900. Leeham News and Comment broke the story of the A321LR last October. The program was officially launched the following January.

Singapore Air and Airbus Want to Bring Back the World's Longest Nonstop Flight
Andrea Rothman Julie Johnsson
August 17, 2015 — 1:33 PM CESTUpdated on August 17, 2015 — 6:33 PM CEST
Airbus Group SE’s airliner unit is working on a new variant of its A350-900 wide-body that would allow Singapore Airlines Ltd. to restore nonstop U.S. flights and regain the record for the world’s longest airline sector.
Airbus, which began deliveries of the twin-engine model last year, is working on changes to the cabin layout that would reduce the aircraft’s weight and let Singapore Airlines reach New York economically by 2018, said Kiran Rao, the planemaker’s executive vice president for strategy and marketing.
“I can’t go into details on the type of layouts they’re looking at but it would be a premium service”Singapore Air halted near 19-hour direct flights from its home hub to New York in 2013, adding about five hours to the journey with stopovers. Chief Executive Officer Goh Choon Phong said in June there was no commercially viable jet available and that he was pushing both Airbus and Boeing Co. for proposals.
Rao said the A350 should be able to make the trip with 25 percent less fuel burn than older models, at the expense of a less dense layout than the usual 325-seat, three-class -900, which could be available “an awful lot quicker than Boeing.”
The U.S. manufacturer could offer a development of its 787-9 Dreamliner for extended operations if it wants to compete in that area, according to Richard Aboulafia, an analyst at Teal Group in Fairfax, Virginia. “Its market potential is pretty small, but it’s prestigious,” he said.
Business-Only
Several other airlines have expressed an interest in such a variant, Rao said, while declining to identify them.
“I can’t go into details on the type of layouts they’re looking at but it would be a premium service,” he said. When Singapore Air last flew to the New York area directly it did so with just 100 business-only seats on a four-engine Airbus A340-500, an arrangement that ultimately proved non-viable.
The route, to Newark in New Jersey, was the longest non-stop commercial air service ever offered at 15,344 kilometers (9,536 miles).
Boeing’s older 777-200LR -- the longest-range jetliner available today -- could make the distance, according to the U.S. company, and will be used by Emirates to fly the 13,821 km between Dubai and Panama from February. That flight will become the longest single sector currently flown, beating Qantas Airways Ltd.’s Sydney-Dallas Fort Worth route by about 20 km.
The 777-200LR entered service in 2006 and the last delivery to an airline was more than a year ago in April 2014.

Qualcuno esperto di FTL ha idea di quanto sia il minimum rest dell'equipaggio che si spara l'SQ 22/21?
