Boeing 777 famille

Boeing is considering a near-term performance improvement package for the 777-300ER that could result in a 4% decrease in fuel burn.

VP-Marketing Randy Tinseth told ATWOnline that the 4% gain would come from a range of aerodynamic improvements related to the fuselage and wing.

He added that the manufacturer will consider more significant changes before the A350-1000's EIS in 2016. "This may be a new wing and engine combination and possibly a slight stretch," he said.

Boeing last month created a 777 Advanced Product Development team to study the future options for the aircraft. Lars Anderson, former head of the 777 program, came out of retirement to join the team.

Singapore Airlines (SIA) has decided to retrofit 11 of its [Vous devez être inscrit et connecté pour voir ce lien]-200s that mostly operate on routes to China and India.
The Star Alliance carrier says the 11 777-200s will be refitted with a new interior that draws on elements from SIA's [Vous devez être inscrit et connecté pour voir ce lien] A330s, Airbus A380s and [Vous devez être inscrit et connecté pour voir ce lien] 777-300ERs.
It says the first retrofitted 777 will appears on the Singapore-Shanghai route on 23 February and the other 777s will be progressively introduced between April and August.
The other routes that will use these 777s are from Singapore to: Beijing, Mumbai, Delhi, Bangalore, Hong Kong and Chennai.

FAA calls for fix to Boeing 777

Airlines must install new software on Boeing 777s to keep the jets from potentially going off the end of runways.
The Federal Aviation Administration directive, which the agency has not yet posted to its Web site, comes after incidents involving the jet's autopilot.
"Boeing had received operator reports of flight crews inadvertently engaging the autopilot while on the ground," Boeing spokeswoman Sandy Angers explained Tuesday. "When the flight crew inadvertently engages the autopilot during the lower-speed phase of takeoff, the control column forces will be higher than normal when the pilot attempts to initiate takeoff rotation. This can result in a high-speed rejected takeoff, and increases the possibility of a runway overrun."
Angers noted that the 777 fleet has notched more than 4.8 million flights over its 15-year history, with just nine reported instances of a rejected takeoff because of inadvertent engagement of the autopilot and no runway overruns or injuries associated with the events.
Boeing supports the FAA's rule, which "essentially mandates the service bulletin Boeing issued to operators on Jan. 22, 2010," Angers said. The service bulletin advised airlines to install new software that prevents flight crews from inadvertently engaging the autopilot before takeoff.
The fix ultimately could affect more than 800 777s worldwide, The Wall Street Journal [Vous devez être inscrit et connecté pour voir ce lien] Tuesday.

US aviation watchdog, the Federal Aviation Administration, on Tuesday ordered Boeing to fix a software problem in hundreds of 777 aircraft that could cause them to overrun the runway.

ATLANTA -- The Federal Aviation Administration wants new software installed on Boeing 777s to prevent crews from inadvertently engaging the autopilot before takeoff.

The problem can result in a high-speed rejected, or aborted, takeoff and increase the chance of a runway overrun.
Boeing says the problem is rare -- just nine reported instances of a rejected takeoff because of inadvertent engagement of the autopilot during the 777's 15-year service history.

Two incidents occurred in January. There have been no runway overruns or injuries associated with the issue.
The airworthiness directive is to be published in the Federal Register on Wednesday.
The rule, which applies to certain model 777-200, 777-200LR, 777- 300, 777-300ER and 777F series airplanes, takes effect 15 days later.

Boeing said it supports the FAA's directive.
The company said the directive essentially mandates the service bulletin it issued to 777 operators on Jan. 22.
Boeing shares fell 68 cents, or 1 percent, to close at $68.72 in Tuesday trading.

Virgin Blue Group canceled two 777-300ERs on firm order for its V Australia subsidiary scheduled for delivery next year, converting the order to two options for 2012 delivery.

The company said the move is designed to allow new CEO John Borghetti an opportunity to review fleet strategy. One option under consideration is to take a few "early 787s that have become available," sources tell ATWOnline. Last month, Virgin Blue ordered up to 100 737s for its domestic, New Zealand and regional international flights.

Angolan flag-carrier TAAG has announced an order two [Vous devez être inscrit et connecté pour voir ce lien]-300ERs in a deal that includes purchase rights for two additional 777-300ERs.
The two aircraft are valued at about $544 million at list prices, says [Vous devez être inscrit et connecté pour voir ce lien], which did not say when the aircraft will be delivered.
TAAG's order was originally posted as unidentified on the airframer's orders and deliveries website in 2009.
The airline will operate the aircraft on new routes to additional European destinations, says Boeing. "TAAG currently flies Boeing 777-200ERs 10 times weekly from Luanda, Angola, to Lisbon, twice weekly to Beijing via Dubai and four times weekly to Rio de Janeiro," it adds.
TAAG is allowed to use only 777 and 737-700 aircraft in Europe due to safety regulations set down in the European Union's airline blacklist.
"The efficiency, reliability and popularity of the 777 family will contribute to TAAG re-establishing itself as one of Africa's premier airlines," says Marlin Dailey, VP of sales, Boeing Commercial Airplanes.

Singapore Airlines (SIA) has finalised a deal with Russian carrier Transaero for the sale of four [Vous devez être inscrit et connecté pour voir ce lien]-200ERs and other carriers such as [Vous devez être inscrit et connecté pour voir ce lien] Airlines and Portugal's [Vous devez être inscrit et connecté pour voir ce lien] are also speaking to SIA about acquiring 777s.
"We have now finalised an agreement with Transaero covering the sale of four 777-200s, manufacturing serial numbers 28998, 28999, 28514 and 28523," says a SIA spokesman.
Flightglobal's ACAS database says these are all -200ERs and three were built in 1998 while 28523 was built in 1999.
These aircraft are all in a two-class configuration, the spokesman adds.
Transaero announced late last month it would be getting 14 ex-SIA 777s but the SIA spokesman says "at that point [last month] it was a letter-of-intent" only whereas now the deal has been finalised.

SIA's spokesman declines to comment on whether Royal Brunei and EuroAtlantic Airways will be getting ex-SIA 777s as well.

But a Royal Brunei spokeswoman says the carrier does plan to add 777s in June and is working to finalise a deal in the coming days.
"It is no secret that the party we are speaking to is SIA," says the spokeswoman. Royal Brunei's CEO, Robert Yang, is SIA's former VP for eastern USA and South America.

Royal Brunei's online booking engine shows that it plans to replace its [Vous devez être inscrit et connecté pour voir ce lien] 767s on the Bandar Seri Begawan-London Heathrow route starting 24 June but the service will continue to have a stop-over in Dubai.
Its non-stop Bandar Seri Begawan-Brisbane service will switch from 767s to 777s effective 25 June, it says.
National carrier [Vous devez être inscrit et connecté pour voir ce lien], meanwhile, has added an ex-SIA [Vous devez être inscrit et connecté pour voir ce lien] and this aircraft is leased from Portugal's EuroAtlantic Airways.

"We have one [ex-SIA 777-200ER] in the fleet with another 777-200ER in the process," says the spokesman, adding that the second aircraft will also be an ex-SIA aircraft on lease from EuroAtlantic.
He says the carrier is also talking to EuroAtlantic about adding a third and fourth 777-200ER.

Boeing Engineer Patents Design for Small, Double-Aisle Plane
Source: St. Louis Post-Dispatch. Publication date: 2005-01-21

Jan. 21--Days before [Vous devez être inscrit et connecté pour voir ce lien]'s recent announcement that it was ending production of its smallest commercial jet -- the unpopular, single-aisle 717 -- a top engineer at the company secured a U.S. patent for the design of a small, double-aisle plane that promises efficiency and comfort.

Voilà un fait historique (histoire récente).

In many cases, passenger comfort has been a casualty of the airline industry's move to buy smaller, fuel-efficient planes to ferry travellers on short-haul routes. The culprit has been the cramped, single-aisle configuration embraced by regional and low-cost carriers.

Boeing engineer Mithra Sankrithi's patent, No. 6,834,833, contemplates a small, double-aisle plane with more space and the fuel efficiency coveted by airlines. Received Dec. 28, it could have multiple configurations, but it generally would seat fewer than 200 passengers.

Voila pour le nombre de passagers, ... envisagé initialement à l'époque.

Mais, depuis l'époque de cet article, les personnes que cela intéressaient, et qui savent de quoi elles parlent, ont évoqué une évolution dans les réflexions (qui n'a rien d'officiel, et qui ne sera jamais 'reconnue'). Les réflexions portaient, paraït-il, sur la possibilité ce faire une famille de deux avions de ce type : un de 190 à 200 places, et un "stretch" capable de transporter 225 à 240 paasagers, ce chiffre de 240 constituant le plafond (en term du nombre de passagers à transporter).

His patent also envisions a design that reaches out to multiple classes of planes.

Ceci n'est absolument pas une garantie de développement & de production, ... ensuite !

Richard Aboulafia, an aerospace analyst at Teal Group Inc., said 200-seat planes have been the fault line between narrow and wide-body jets. "It's been hard for airplane makers to decide if these planes should be one or the other."

The market, however, has dictated that anything less than 200 seats should be a narrow body, Aboulafia said.

"You have to do something aerodynamically new to have the twin aisle make sense," he said. "Width is the enemy of economy."

Il est vrai que ceci réfléchit la façon de penser de l'époque, ..... et bien avant, aussi.
.................

One embodiment of Sankrithi's patented design calls for two aisles, each at least 17 inches wide and 75 inches high from floor to ceiling.
There would be several rows of at least seven seats, with each seat bottom measuring 17 inches across. In contrast, a larger Boeing 777 has seat bottom widths of 18.5 inches and aisle widths of 19 inches. Boeing was not available for comment. It also isn't clear if Sankrithi's vision ever will go beyond the drawing board. He is manager of Boeing's commercial airplanes product development, configuration and engineering analysis group.

Voir notre remarque ci-dessus.

Tom Leritz, an aerospace analyst at Clayton-based Argent Capital Management, said airlines want planes that match the supply and demand of their routes. Network carriers, such as American Airlines, fly fewer bigger planes and increasingly have leaned on regional carriers to operate the smaller jets. Airlines also are trying to cut expenses by standardizing their fleets.

J'espère que ceci est une entrée en matière raisonnable. Je reviendrai plus tard sur l'aspect "rayon d'action" .
