A new era of ‘ultra-long-haul’ aviation

A new era of ‘ultra-long-haul’ aviation, If the anticipation of getting cooped up on a long-haul even adventure fills you with dread, additional a anticipation for cartage appointed on to Emirates flight EK251. On February 1, the new circadian account will leave Dubai at 8.05am. Its 266 cartage will again accept time to watch eight movies aback to aback and adore abundant in-flight commons afore the ceaseless account arrives in Panama City, 17 hours 35 account afterwards demography off.

The Emirates flight, accoutrement 8,587 miles, will yield the appellation of longest appointed commuter service, trumping Qantas’s absolute Dallas-to-Sydney flight (about 17 hours) — but it isn’t an aberration, nor a publicity stunt, from the aggressive Gulf carrier.

In actuality Emirates is absurd to authority on to the appellation for long, acknowledgment to a renaissance in alleged “ultra-long-haul” flying. A new bearing of aircraft is allowance to accomplish best flights added efficient, and both Boeing and Airbus are alive on extended-range models — the Airbus A350-900ULR and Boeing 777-8 — that will access account in the next 5 years. The closing appearance added continued wings to advance achievement which accept to be bankrupt up on landing so the even will fit airport taxiways.

“The technology is now there to do these ultra-long-haul flights added efficiently, so airlines are searching at area it makes faculty to accomplish them,” says John Strickland, an aerodynamics analyst and architect of UK-based JLS Consulting.

Last ages Qantas appear it was because ablution ceaseless flights amid Australia and Europe by 2017, including a Perth-to-London route, application the eight new Boeing 787-9 aircraft it has ordered to alter its 747s. At the aforementioned time, Singapore Airlines appear affairs to fly absolute from Singapore to New York, starting in 2018. The flight would yield about 19 hours, awning 9,522 afar — and snatch the almanac for the longest ceaseless flight.

In fact, such super-long ceaseless flights are not new. A decade ago, these routes seemed to be arising as a key trend — Thai Airways launched absolute flights from Bangkok to Los Angeles in 2005, the aforementioned year that American Airlines began aerial ceaseless from Chicago to Delhi. The antecedent year Singapore Airlines had launched flights from Singapore to New York and Los Angeles.

But the aerial amount of ammunition in 2009 and 2010, accompanying with the bread-and-butter crisis, which bargain the amount of barter accommodating to pay a exceptional for such flights, fabricated them uneconomic, and by backward 2013 every one of those routes had been cancelled. Part of the botheration was that abounding of the routes acclimated gas-guzzling four-engined A340-500 aircraft — dubbed “flying ammunition tankers” by industry commentators. “On an ultra-long-haul flight, a even takes off with ammunition that artlessly carries the burden of ammunition that will be acclimated hours later,” says Will Horton, analyst at the Sydney-based Centre for Aviation. “On these flights, if the oil amount was high, ammunition took up the all-inclusive majority of the amount of the flight — aloft 70 per cent.”

When Singapore Airlines aboriginal placed orders for the A340-500, ammunition was 42 cents a gallon. At access into service, this had risen to 93 cents, and it was $2.83 if the flights concluded in 2013. “While the flights may accept been accepted to be bordering or a bit lossmaking, they concluded up getting abundant drainers,” says Horton.

Two years on, Singapore Airlines is planning to accost its distance-flying almanac in a added fuel-efficient manner. If it restarts absolute flights to New York in 2018, it will be as the barrage chump for the new Airbus A350-900ULR. Its abundantly blended anatomy has helped Airbus abate the aircraft’s weight, acid ammunition burn: the architect claims it will absorb 25 per cent beneath ammunition than the similar-sized Boeing 777-200LR. The new Airbus will aswell accept continued ammunition tanks compared with added variants of the A350 family. With a best accommodation of 165,000 litres, it will accept a ambit of at atomic 10,357 afar — added than any added airliner.

“Most of our barter say ceaseless was the alone way to biking from the US to Southeast Asia,” says Subhas Menon, Singapore Airlines’ bounded vice-president for Europe. “When you accept average stops, the timing of the flights and all these things arrest your rest.”

With one or two layovers, the adventure from Singapore to New York can yield amid 24 and 30 hours. Paul Wait, arch controlling of GTMC, which represents business biking companies in the UK, argues that a absolute air avenue will consistently be preferable, decidedly for able travellers. “Ultra-long-haul is perceived by the business biking association as a abundant befalling for advantageous alive hours, which are generally aswell billable,” he says.

The plane-makers aswell affirmation that new technology will accomplish the acquaintance of continued flights added bearable for passengers. For example, application carbon-fibre-reinforced composites — such as in the Boeing 787 and the accessible Airbus A350-900ULR — permits a college berth humidity. “Humidity is one of the factors that makes the commuter acquaintance better,” says Blake Emery, administrator of adverse action at Boeing. “If you cascade baptize over artificial it is no big deal. But if you cascade it over metal aggregate will corrode.”

Composite fuselages that are not affected to bane aswell admittance a college centralized berth pressure, something that Emery says is apparently the a lot of important agency in commuter comfort. Getting it amiss can aftereffect in abhorrent symptoms, abnormally on actual continued flights: “Some humans accept headaches and beef aches,” he says. Conventional earlier aircraft usually accept a berth burden agnate to that at 8,000ft aloft sea level, but on the blended 787 it is the agnate of 6,000ft (a akin Boeing absitively was optimal afterwards administering all-encompassing tests that complex paying acceptance at the University of Oklahoma to absorb 18 hours central a apish aircraft set to altered pressures).

Nevertheless, for some, getting ashore on an aeroplane for added than 18 hours is too abundant to bear. “You would alone wish to do it on a avenue if you fly premium[class] because the abstraction of getting in abridgement for that continued is appealing grim,” says Strickland. “No amount how avant-garde the aircraft is, if you anticipate about all the practicalities like deep-vein occlusion and so on, you absolutely would adopt to be in the exceptional seats.”

To advice awning an airline’s college ammunition and agents costs, ultra-long-haul casework await on alluring a cogent amount of business travellers who are able to pay a exceptional for a ceaseless flight. Singapore Airlines inaugurated its longest avenue in 2004 with both business and abridgement seats; four years later, it had adapted the aircraft to alone business-class. Long-haul airliners aswell accept to agency in in-flight blow accessories for aggregation and pilots — and even a abode to accumulate the bodies of any cartage who appear to die during the flight. In its agile of A340-500 aircraft, Singapore Airlines alien a appropriate buffet to abundance any abrupt corpse.

The bloom risks of aerial such continued distances aswell affect the pilots. Those alive on long-haul routes accept the arresting hazard of timezone-related circadian accent (body clock) disruption. Best times spent on flights can aswell beggarly greater acknowledgment to radiation.

“There are rules apropos hours of plan and blow and the amount of pilots acclimated on long-haul flights,” says Rob Hunter, arch of flight assurance at the British Airline Pilots’ Association, “but added airlines are getting accustomed to access exceptions to these rules if they can authenticate that these exceptions are safe.”

Hunter says he is anxious that bartering pressures on airlines may accommodation their decision-making. “Part of the ecology and ascendancy of the hazard of fatigue in pilots are pilots’ [own] letters of their tiredness. It is not aberrant for such letters to be managed by the airline with a antidotal tone. For abounding pilots it is beneath backbreaking to put up with fatigue than to address it,” he says.

The barrage of added ultra-long-haul flights in the advancing years is acceptable as technology improves. Emirates says it will be able to fly even best ranges if it takes supply of the Boeing 777-8 in 2020. This could acquiesce the airline to extend ceaseless flights to destinations such as Peru, Mexico City and Santiago in Chile, says Anand Lakshminarayanan, chief vice-president of acquirement optimisation at Emirates.

“The primary agency is demand, really,” he says. “From what we’ve apparent there is a alertness from cartage to pay hardly added for an ultra-long-haul flight after an agent stop.”

Nevertheless, abounding aural the industry accept these flights will consistently abide a niche. According to Strickland, just because ultra-long-haul flights are technically achievable does not beggarly that they will consistently accomplish bread-and-butter sense. Meanwhile, Will Horton credibility out that abounding cartage in fact adore a adopted stopover, while some artlessly will not wish to be on an aircraft for so long.

“The engine technology is there,” says Alan Epstein, Pratt & Whitney’s vice-president for technology and a above aerospace assistant at the Massachusetts Institute of Technology. “We can now fly just about any abode on this apple nonstop. The absolute is no best the ability of the engines. It is the ability of passengers.”
