Australia reaffirms confidence in current search zone for missing MH370 flight

Australian authorities have expressed renewed confidence that they will find the missing Malaysia Airlines flight MH370 within the current search zone.

Australian Deputy Prime Minister Warren Truss held a press conference on Thursday to announce that more than three-quarters of a "hot spot" area within the current search zone had been scoured for the plane that disappeared on March 8 last year.

Truss said the search teams remained hopeful that the missing airliner will be located in the final portion of the search zone.

"There's around 44,000 square kilometers yet to be searched in this new priority area, and we're optimistic and hopeful that the search will result in us locating the aircraft," Truss said.

The Australian Transport Safety Bureau (ATSB) said earlier on Thursday new analysis had reaffirmed "the highest probability" that the aircraft was located in the search zone.

Martin Dolan, chief commissioner of the Australian Transport Safety Bureau, revealed to reporters that teams, armed with new analysis from Australia's Defence Science and Technology Group, were also rechecking priority areas.

Investigators had turned to 18th-century statistician Thomas Bayes to help map out the probable fate of the aircraft, Dolan said.

"I am very confident in the Bayesian analysis," Dolan said.

There is precedence as the English theologian's pioneering work on probability helped locate Air France Flight 447 almost two years after it plunged into the Atlantic Ocean in 2009.

At the heart of Bayesian analysis is the quantification of a set of uncertainties. These calculations are continually updated as new information comes in. So in a hunt for a missing person, plane or ship, for example, even unsuccessful patrols can be helpful. The US Coast Guard's search and rescue teams rely on similar methodology.

The search for the Malaysia Airlines plane has been focusing on a 120,000 square kilometer 'arc' of the southern Indian Ocean off Western Australia.

A flaperon from the Boeing 777-200ER was washed up in July on Reunion Island-- a French overseas department off the east coast of Madagascar, but no other trace of the plane has been found.

Australia's retired Air Chief Marshall Sir Angus Houston is leading the search for the wreckage.

MH370 disappeared after it departed Kuala Lumpur en route to Beijing with 239 people on board.

  1. MH370 search: Australia 'likely looking in right place'...

    Australian officials say they believe they are searching in the right area for Malaysia Airlines flight MH370.

    A new analysis of data carried out by a defence department shows the plane is probably in the southern end of the Indian Ocean search zone, where the operation will now be focused.

    MH370 was en route from Kuala Lumpur to Beijing when it disappeared in March 2014 with 239 people on board.

    Deputy PM Warren Truss said officials were "optimistic" it would be found.

    But he said the search operation was likely to end by June 2016......BBC

  2. MH370: les recherches se font au bon endroit, annonce l'Australie...

    L'Australie a annoncé jeudi que de nouvelles données sur la disparition du vol MH370 confirmaient que les recherches qu'elle dirige se déroulent au bon endroit, laissant espérer qu'un jour l'épave sera retrouvée.

    L'Australie a pris la tête des recherches pour tenter de retrouver le Boeing 777 de Malaysia Airlines. Celui-ci s'est volatilisé le 8 mars 2014 peu après son décollage de Kuala Lumpur pour Pékin, avec 239 personnes à bord, et se serait abîmé dans l'océan Indien.

    Sur la base de relevés satellitaires sur la possible trajectoire de l'avion, qui avait dévié de son plan de vol, des bateaux explorent les fonds sous-marins au large de la côte ouest de l'Australie. Ils ont parcouru jusqu'ici 75.000 kilomètres carrés, sur une zone de recherches estimée à 120.000 km2, sans résultat.

    Le vice-Premier ministre australien Warren Truss a expliqué que le Groupe des sciences et de la technologie de l'armée australienne avait été chargé de croiser à nouveau toutes les données disponibles, afin d'être sûr que rien n'avait été mal interprété.

    Ses conclusions, fondées sur des modèles de données Inmarsat de communications par satellite, de dynamique aéronautique et d'informations météorologiques, ont été rendues publiques jeudi.

    "Les principaux résultats de ce travail supplémentaire valident ce qui a été jusqu'alors entrepris. Ils confirment que l'avion se trouve probablement quelque part dans ces 120.000 kilomètres carrés", a-t-il déclaré.

    "Cela nous encourage et atteste que tous les efforts sont faits pour que les recherches soient bien orientées et, comme nous l'espérons, porteront un jour leurs fruits", a ajouté Warren Truss......AFP......http://www.france24.com/fr/20151203-mh370-recherches-font-bon-endroit-annonce-laustralie
