The technology insertion is really more around recovering your time-on-wing back to the same sort of levels as the 84,000lb engine, by giving you a greater turbine gas temperature margin," says Young. "It's a maintenance cost resetting via use of technology."

The engine core improvements developed for the 2015 entry-into-service of the A350-1000 could eventually be incorporated into earlier versions of the Trent XWB that will by then be in service on the -800/900 models.

"The intent is that the new core [for the -1000] would have the capability of being read across to all of the previous [-800/900] engines" says Young, who adds that decisions to upgrade engines already in service will be looked at on a case-by-case basis.

Air France-KLM Group issued a request for proposals for 787s and A350s last year, "but this tender is 'asleep' because both Boeing and Airbus are not able to provide clarity on delivery dates," KLM President and CEO Peter Hartman told Luchtvaartnieuws.nl.

L'idéal aurait été un A 350 à moteurs GE, soit le GenX.

Il était "urgent d'attendre" ( vision & cash...)

Airbus announced A350 supplier contracts with Panasonic Avionics Corp. on OnAir, its joint venture with SITA. Panasonic will provide on-demand audio and video, eXPhone inflight mobile phone service, eXConnect broadband Internet and its Panasonic Airborne Television Network. OnAir's connectivity technology will be linefit offerable on the A350, the company said, adding that more than 40% of A350 customers have ordered the product.

Pour améliorer la maintenance et la logistique du futur avion A350 XWB mais aussi pour éviter les contrefaçons, Airbus a décidé de faire appel à la [Vous devez être inscrit et connecté pour voir ce lien] afin de marquer plus de 1.500 composants et systèmes, en zone pressurisée et non pressurisée, de chaque avion. L'A350 XWB sera le premier appareil d'Airbus à utiliser cette technologie d’identification qui sera mis en œuvre avec la participation des équipementiers d'Airbus. Une première mondiale pour la sécurité aérienne.
Ce programme prévoit de déployer des étiquettes RFID durcies à large mémoire qui contiendront les dates et informations de conception ainsi que l’historique complet de l'entretien des pièces de l’avion, ce qui permettra l’optimisation des opérations de maintenance, réparation et révision (MRO : Maintenance, Repair & Overhaul).
Airbus avait lancé un appel d’offres auquel avait notamment répondu de grandes entreprises asiatiques comme Fujitsu. Finalement il a retenu la solution développée et produite conjointement par MAINtag SAS, jeune entreprise française, leader du marché des systèmes RFID et Tego, Inc, fournisseur de puces RFID large mémoire.
Chef de file et principal fournisseur du contrat signé sur plusieurs années avec Airbus, MAINtag qui a relocalisé sa production en France, livrera la solution FLYtag conformes aux spécifications aéronautiques mondiales. Il s’agit d’un tag RFID UHF Gen2 (850 – 960 MHz) destiné à l'identification et la maintenance pour le monde aéronautique. Construit pour des conditions extrêmes d’utilisation (températures comprises entre -25°C et +85°C, accélérations comprises entre -0,5 g et +4g…), il est adhésif et de faible encombrement. La gamme FLYtag qui se décline en 2 modèles, intègre la puce passive RFID à large mémoire TegoChip de Tego qui supporte jusqu'à 32 kbytes de données et est actuellement disponible avec la gamme FLYtag compatible métal, dans une configuration 4 kbytes puis 8 kbytes dès la fin de cette année. Avec 32.000 bytes de capacité mémoire, la puce TegoChip dépasse de loin les 512 bits couramment disponibles aujourd’hui sur le marché.
" La combinaison de l'expertise de MAINtag et de Tego apporte la technologie RFID la plus avancée sur le marché pour les applications qui nécessitent une grande capacité de mémoire dans des environnements hostiles ", conclut Bruno Lo-Ré, président de MAINtag.

Honeywell has completed ground testing of the HGT1700 auxiliary power unit (APU) designed for the Airbus A350 XWB.
The company says the APU passed the first engine to test (FETT) phase in October of 2009.
Honeywell explains that unlike its predecessor APUs, the HGT1700 features variable speed during ground operation to cut fuel burn by up to 10%, a new hydraulic bleed valve to improve reliability, an improved combustor to reduce clogging and improved durability.

Airbus in September of 2007 awarded Honeywell a $16.5 billion contract covering the A350 XWB's APU and air management system.
Honeywell won a follow-on $1.5 billion contract in March 2008 to supply the aircraft's flight management and environmental surveillance systems.

Airbus posied to reveal details of A350 XWB catalogue

[Vous devez être inscrit et connecté pour voir ce lien] intends to reveal more detailed information about its [Vous devez être inscrit et connecté pour voir ce lien] XWB catalogue following an airline customer event next month, the airframer tells ATI.
"The development of the A350 XWB customer catalogue is at a mature stage but of course under constant review with customers and the extended enterprise partners. It is designed to also incorporate future innovations," says an Airbus spokesman.
"After our next A350 XWB customer event mid of April we will provide more detailed information on the catalogue and its content."
Airbus has already begun announcing partnerships with various in-flight entertainment and connectivity (IFEC) and interiors suppliers to the A350.
The airframer's joint venture with SITA, the in-flight connectivity service provider known as OnAir, was recently selected to be linefit offerable on the aircraft.
Airbus also intends to make Panasonic Avionics' IFEC solutions - including its Ku-band satellite-based eXConnect system - line-fit offerable on the A350, once Panasonic shows it meets the airframer's architectural requirements for the widebody twinjet.
In the interiors space, Airbus has signed a contract with Recaro with the intention of offering the aircraft seat manufacturer's lightweight Comfort Line CL3620 economy class seats on the A350. A version of the seat is already installed on Qantas' Airbus A380s.
Once the A350 catalogue is defined, airline customers will be required to select economy class seating from the catalogue.
"The economy seating is following the catalogue offer. First class and business class configurations can be outside of the catalogue offer, but have to come from Airbus contracted suppliers," says the Airbus spokesman

BERLIN, 21 mars 2010 (AFP)

Le gouvernement allemand est prêt à accorder un prêt de 1,1 milliard d'euros à l'avionneur européen Airbus pour le développement de son futur long-courrier A350, affirme le secrétaire d'Etat parlementaire au ministère de l'Economie, le député Peter Hintze.

2010 AFP

In remarks made during their full year earnings, EADS had noted how it had used up “some of the previous buffers” for the A350XWB’s development. Concerns seem to be growing that there could be slippages in the program although Airbus continues to assert that entry into service for the baseline A350-900 model will still occur in 2013.

As one of the biggest customers for the A350XWB family, Emirates has made known its concerns about delays in the program with a stinging rebuke about execution and program margins.

Emirates President Tim Clark was cited by Aviation Week as saying “we have clearly told Airbus that we will not accept again what they did to us with the A380.“

Clark goes on:

“We have told Airbus numerous times that in our view they should build in more margin in terms of time and performance parameters, but they wanted to have it their way. Now they are already eating into margins.“

“All I have to do is pick up the phone and order more Boeing 777s,” he said.

Emirates has stated recently that it may be poised to order more 777’s, and in comments made to the JP Morgan conference last week, Boeing Commercial Airplanes’ CEO Jim Albaugh said that he “[Vous devez être inscrit et connecté pour voir ce lien]“

While it remains to be seen if Emirates’ concerns extrapolate into serious program delays, Teal Group’s Richard Aboulafia has already surmised that the A350XWB could be up to two years late.

It was these same sorts of musings that led to the crippling delays on Boeing’s flagship 787 program but [Vous devez être inscrit et connecté pour voir ce lien] Founder & Chief Consultant Doug McVitie noted that Airbus is deliberately “delaying the inevitable.”
“They know the airplane is going to be late, they just don’t want to admit it,” he said.

Airbus has tentatively marked the first quarter of 2012 for the A350-900’s first flight with service entry around the middle of 2013.

Didier Evrard, head of the A350XWB program says that Airbus is “developing this aircraft faster and putting in place a lot of new enablers in developing a new industrial vision, a new way of doing business with our suppliers and of doing customisation with our customers.”

Emirates is concerned that this rapid-paced approach is ultimately going to “undo” further program buffers and that the customisation which has debilitated the A380 production will rear its head again on the A350XWB. Radio silence from launch customer Qatar Airways adds to the uncertainty, particularly given its deep criticism over the lack of engineering information when the A350XWB was launched.

While delays on new programs seems to have become an accepted norm within the last half decade, the bigger problem is the waiting game for airlines - will there, or won’t there be delays on the A350XWB?

Right now it’s pretty hard to bet against the views of Aboulafia and McVitie when Emirates has been so vivid in its comments to Airbus.
