Malaysia Airlines volo MH370 disperso - PUBBLICATO IL REPORT FINALE


Re: Malaysia Airlines loses contact with MH370

Con questa scarsezza di informazioni mi sento di dire solo una cosa: un 777, che sia esploso in volo o sia ammarato non può essere scomparso nel nulla.
Mi viene quindi da pensare che non si stia semplicemente cercando dove si deve cercare. E la reticenza delle autorità malesi di certo non aiuta.

Il fatto che non si trovi nulla in una delle aree più affollate del pianeta e con copertura radar mi lascia veramente basito. Manco fossimo nel mezzo del Pacifico meridionale.

Aggiornamento da avherald:

On Mar 12th 2014 Vietnam's Search and Rescue Control Center reported that analysis of satellite images of Vietnams coastal regions, capable of showing objects sized 2.5 meters by 2.5 meters, did not detect any signs of the aircraft. Around noon the Control Center reported, that the search operation continues in full like the days before based on official information from Malaysia that the aircraft has not been tracked in the Strait of Malacca. 9 Vietnamese aircraft and 9 Vietname ships plus 14 foreign aircraft and 22 foreign ships are searching Vietnamese waters.

On Mar 12th 2014 officials of Malaysia's Civil Aviation Authority talking to families of occupants of MH-370 in Beijing reported that the aircraft was just in the process of being handed off to Vietnam, the last radio transmission heard from the aircraft was "Okay, good night". The crew did not report on Vietnam's frequency anymore. About three minutes later Vietnam's control center noticed that the aircraft had disappeared from radar and had not reported on his frequency. There had been no emergency or distress calls on any means of communication, although radio coverage of the area is generally good. Malaysia's CAA officials stressed, that they do not have any indication that the aircraft may have turned back or deviated from the planned route. The aircraft "suddenly disappeared". So far the aircraft has not been found although a total of 1788 ships are participating in the search for the aircraft.

Editorial note on Mar 12th 2014: On Mar 10th Malaysia expanded the search area into the Strait of Malacca assigning substantial forces to that large search area (much larger than the search area in the Gulf of Thailand with a radius of 100nm around the last known secondary radar position east of Malaysia). It remains unclear why this has been done given the Mar 12th denials of reports of Mar 11th that the aircraft may have been tracked by primary radar into the Strait of Malacca explaining that widened search. It also remains unclear why on Mar 12th the search is now moving northwest into the Andaman Sea west of Malaysia, especially when there are/were no indications of the aircraft turning back as Malaysia officials told families in Beijing on Mar 12th.

Secondo me questo è un punto molto importante: perchè i malesi stanno cercando un aereo in una zona lontanissima dal percorso originario e nel contempo non vogliono ammettere che hanno una traccia radar che ha "visto" l'aereo nello stretto di Malacca?
È come se in Italia sparisse un aereo nell'alto Adriatico diretto in Germania e lo si cercasse di fronte a Capri, negando allo stesso tempo di avere tracce radar nel Tirreno. Che senso avrebbe?
Se i malesi non cominciano a dare spiegazioni logiche dei loro atti, inizierà ad affiorare il sospetto che abbiano qualcosa da nascondere. E con più di 200 morti a chiedere giustizia, non mi sembra il caso.

MH370 probe attempts to identify Malacca radar target

By: MAVIS TOHSINGAPORE Source: 2 hours ago

Malaysia's air force has yet to identify the source of a contact picked up by radar over the Straits of Malacca, about 45min after the disappearance of the Malaysia Airlines Boeing 777-200.
Speaking at a press conference today, Royal Malaysian Air Force chief Rodzali Bin Daud said military radar detected an "unidentified plot" at 02:15 on the morning of 8 March. The source of the contact was some 200nm (370km) northwest of Penang, at an altitude of 29,500ft.
But the air force, which has already had to clarify confusion over evidence that flight MH370 might have attempted to turn back to Kuala Lumpur, is stressing that the significance of the radar plots has yet to be determined by investigators.
“I’m not saying this is MH370. We’re still working with the experts on this. It is an unidentified plot,” he says, adding that data from the radars have also been shared with officials from the US Federal Aviation Administration and the National Transport Safety Board.
While secondary radar interrogates the aircraft's transponder, providing key flight data, the primary military radar does not, explains Azharuddin Abdul Rahman, director general of Malaysia's Department of Civil Aviation.
He adds that MH370 was identified on secondary civil radar at about 01:21 before it “disappeared altogether” nine minutes later at 01:30. Primary radar was unable to pick up the aircraft's trace at this time, says Azharuddin.
Rodzali says the unidentified Malacca plot was detected after a review of military data on 8 March. He has not indicated the location of the radar which provided the data. The plot at 02:15 was the last of several "intermittent" contacts, he says.
Although the investigation is considering the possibility that MH370 tried to turn back to Kuala Lumpur, and has extended its search to the Straits of Malacca, defence minister Hishammuddin Hussein says: "If we were sure it was in the [Straits] we'd have moved all our [search] assets there."
The two search zones comprise a 12,425nm2 area over the Straits and a 14,440nm2 over the South China Sea.
Twelve countries, 39 aircraft and 42 vessels are involved in the search.
MH370, which was on the Kuala Lumpur-Beijing route, lost contact with air traffic control on 8 March. Its last known location was approximately midway between the Malaysian town of Kota Bahru and the southernmost tip of Vietnam.

Malaysia Airlines MH370: Last communication revealed

The last communication received from a Malaysia Airlines plane suggests everything was normal on board minutes before it went missing over the South China Sea, Malaysian authorities say.

Flight MH370 replied "All right, roger that" to a radio message from Malaysian air control, authorities said.
The search has been widened to waters off both sides of the peninsula.
Malaysia's air force chief has denied reports the plane was tracked to the Malacca Strait in the west.
The China-bound plane went missing on Saturday with 239 people on board.
It vanished about an hour after it took off from Kuala Lumpur International Airport, as it flew over the South China Sea, south of Vietnam's Ca Mau peninsula. No distress signal or message was sent.
'Confusing' information'
Malaysian authorities revealed the plane's last communication at a news conference held in Beijing for relatives of the 154 Chinese who are among the missing passengers.
As the plane reached the boundary between Malaysian and Vietnamese airspace, the Malaysian air control announced it was handing over to Ho Chi Minh City Control.
Minutes later, all contact with Flight MH370 was lost.
China's foreign ministry said there was "too much confusion" regarding the information released about the plane's flight path.
"It is very hard for us to decide whether a given piece of information is accurate," spokesman Qin Gang told reporters in Beijing.

Re: Malaysia Airlines loses contact with MH370

In the evening of Mar 12th 2014 the commander of Malaysia's Air Force confirmed in a televised news conference, that an unidentified radar target was picked up at FL295 about 200nm northwest of Penang (Malaysia) (editorial note: this translates to just off the coast of Phuket (Thailand) in the Andaman Sea). As the primary radar does not identify which aircraft produced the return (other than secondary radar identifying the aircraft via the aircraft's transponder), it is not clear whether that unidentified target was MH-370. This radar observation however prompted Malaysia's Authorities to expand the search into the Strait of Malacca and Andaman Sea.

Domanda: se un primary radar rileva una traccia e il secondary radar rileva l'aircraft transponder, significa che a) non c'era dunque un secondary radar attivo sulla zona, b) o che non e' attivo il transponder stesso? Tutti i velivoli hanno un transponder, militari inclusi?
 
Re: Malaysia Airlines loses contact with MH370

domanda che potrà sembrare banale, ma tenete conto che sono un profano ella materia...
non ci dovrebbe essere una copertura al 100% da parte del radar del territorio malese, intendo di qualche postazione radar dell'aviazione malese?
se la risposta fosse si, com'è possibile che, nel caso in cui abbia davvero invertito la rotta, non si possa rilevare con certezza un aereo così grande?
e nel caso fosse stato rilevato da qualche radar, è possibile mettere a tacere tutto? mi sembra veramente molto difficile
ultima (banale) considerazione, se l'aereo fosse esploso in aria, visto che tutta l'area è sicuramente sotto copertura satellitare cinese e/o americana, mi sembra assurdo che nessuno abbia visto nulla..
sinceramente non ci sto capendo nulla...

Benvenuto sul forum. :)
Le tue domande sono le stesse che ci stiamo ponendo tutti. E il comportamento reticente dei malesi non aiuta nelle risposte.
 
Re: Malaysia Airlines loses contact with MH370

Premetto che non sono un esperto di avionica ma mi sembrava di avere capito che sugli aerei più recenti ( 777 ovviamente incluso ) proprio per situazioni di questo caso , vi siano 2 "rilevatori"( scusate il termine) di perdita di gravità che in caso di forte discesa all'impatto con il suolo ( e pensavo con l'acqua) emettono un segnale radar che consente di rintracciare il luogo di caduta. Non so se qualcuno ne sappia di più.
