Malaysian Prime Minister Najib.evening of 24 held a news conference to announce a temporary, "according to the latest data, MH370 flight in the southern Indian Ocean, the end." Marfan what made this "conclusion"? The analysis using what means? "Fly" it? People there are many questions. asked why an agency assist in the investigation? Q: why British agencies involved in the investigation? A: According to Najib introduced to the British air accident investigation at the Malaysian side informed that the agency and the International Maritime Satellite Organization analysis, MH370 flight fell into the southern Indian Ocean. British air accident investigation office was established in 1915, currently belonging to the British Department of Transport. International Maritime Satellite Organization, headquartered in London, was founded in 1979 as a non-profit international organization nature, has become a provider of global mobile satellite communications services. Why these two institutions in the survey lost to the flight? British Transport Ministry official on the 24th of Xinhua News Agency, told reporters that the reason for the crash investigation department involved in the investigation of aviation incidents outside the UK, because as long as there is any part of the British-made aircraft, the Department will assist in the investigation, "it is standard procedure, "there is nothing special. asked 2 "Doppler effect" analysis of the signal fly?
Q: Why is never used analysis tools? A: Najib on the 24th, said the two organizations had never been applied by means of an analytical tool in such investigations, concluded that, MH370 flight flying along the Southern Corridor, the last position in the central Indian Ocean .
Najib did not elaborate on what means. Vice President of the International Maritime Satellite Organization McLean in an interview with British media explained that although MH370 flight shut down communication systems, but satellite Inmarsat can still receive from electronic signals sent by the aircraft. It is through the organization earlier this signal may be given to the aircraft lost contact with two north-south corridor.
The organization of scientists and subsequently use the Doppler effect theory a lot of data analysis, based on satellite transmission signal with respect to changes in the frequency, inferred aircraft is flying towards and away from the satellite, combined with other reference factor, and with once in North-South Corridor flying aircraft historical data comparison, given MH370 ultimately to conclusions. McLoughlin said signal their analysis is a simple acoustic pulses, excluding the GPS data, time, location and other information. This signal is relatively weak, issued only once per hour, can only be a satellite to capture and contain minimal amount of information, can not be analyzed by conventional techniques based on multiple satellites, etc., can only be used in the past have not tried the new means.
questioning three partial results by "guess"?
Q: Some rely on "guess" the results are credible?
A: McLoughlin acknowledged that process electronic signals emitted from their last Where in the analysis MH370, partly by "guessing." In an interview with British Sky News interview, said: "We do not know whether the aircraft flying at a constant speed, do not know if it subsequently changed direction."
He said: "Ma flight machine has not been mandated to issue a position signal, so we are" guess
"out of its location which is've never done before.."
The company's experts previously thought, Malaysia Airlines MH370 flight along the north-south corridor in an at least two flight of five hours. Accordingly rescue work shift in the Indian Ocean region.
McLoughlin said, because the screening to determine the signal, so it took 2 weeks to finally come to the conclusion aircraft flying to the southern corridor.
Inmarsat communications department head Jonathan? said they collected some of the other Boeing 777 aircraft data on this same route of flight, and with the assumed route to do comparison, an exact match. These findings before publication is passed another test of a satellite company.
evening of 23 Inmarsat will deliver their conclusions with the British air accident investigation office.
"Before 23, 2009, the British air accident investigation office not sure Malaysia Airlines MH370 flight along the southern corridor." McLoughlin said.
Inmarsat said it belongs satellite companies can pay close attention to the relatively low prices for flights and ground and air exchange to provide data to help better plan flight routes, flight times and fuel savings. This widely used for ship transport system has observation and communications technology that allows air traffic control personnel aware of the location where the aircraft.
McLoughlin stressed that the analysis results through the peer review. Nevertheless, the authorities still wary of their conclusions. White House officials and the State Department spokesman, respectively, lost contact for Malaysia Airlines flights to whether "the end" in the southern Indian Ocean, as well as the fate of missing persons in the United airliner, the United States currently can not be independently confirmed.
It was also noted that the new analytical tools Inmarsat is the first time, the lack of precedent, remains to be validated objects found after plane lost contact. In addition, Malaysia is still not announced to support its conclusion all the relevant information and evidence, which also increases people's concerns. Some netizens said in a message on the 25th British "Economist" magazine website, before the object is found, there is no conclusive evidence on hurriedly announced are "imprudent."
battery runs out of power 30 days time too urgent search black box
find the black box flight MH370 become unlock the mystery of the missing key to work. Black box can usually transmit signals 30 days, from the 8th has been 18 days since lost contact, leaving not much time to search for people.
black box is usually two, one is the flight data recorder, flight data recording all kinds, such as flight time, speed, altitude, etc.; another language recorder to record cockpit and cockpit pilots, pilots of between the cockpit and the passenger's speech voice.
based upon the plane crash, black box signals the battery must be guaranteed for at least 30 days. But some experts say that after 30 days, the black box can be noisy 15 days or longer, depending on the black box of the battery power.
Some experts say that the case did not get the black box, investigators almost impossible to determine the exact cause of aircraft accidents.
by the experts say, in the ocean searching black box, the general need to find the wreckage, then falling designated area, and then find the black box. If you are unsure whether crash [/b]or falling position, look for the black box may be in vain.
Chinese military aircraft on the 24th and were suspected of wreckage floating objects in the search operation, if confirmed belong MH370, will help find the black box.

, weather estimate the actual aircraft crashed position to searchers looking for the black box.
former member of the U.S. National Transportation Safety Board Gaulias said: "This is a race, the black box to receive the signal in time when the black box is still working."
the 24th U.S. Department of Defense confirmed that U.S. military personnel have departed the Australian transport towed sonar can be used to detect the black box and the "，pink drinking straws
;tuna" underwater automatic aircraft. Towed sonar towed slowly by a merchant ship, which is highly sensitive hearing can hear the sound of about 20,000 feet pulse signal (6100 m) deep emitted by the black box.
black box before the battery runs out, if there is no strong signal lock, searchers will have to use side-scan sonar emitted by a device to detect submarine, analysis echoes draw undersea graphics.
through these graphics, experts often do not need to find any abnormal shape or appearance of the seabed in this area.
sonar detection devices can be dragged from one vessel or miniature unmanned submarine, scanning the search area, mapping the seabed graphics, search the wreckage.

Eventually, the sonar to detect evidence of possible wreckage. Another equipped with a high resolution camera underwater vehicle was sent into the sea, so that scientists can detect the area visually.

Australia ready to meet the families of the passengers
Australian Prime Minister Tony? Abbott on the 25th, said he and Malaysian Prime Minister Najib day, Australia will continue to provide support for the MH370 flight search work by telephone.
MH370 flight search in waters about 2,500 kilometers from the Australian city of Perth in southwest southwestern unfold. At this stage, the search and rescue coordinated by Australia in the waters.
Abbott told reporters in Canberra, if the passengers and crew of flight MH370 families choose this "difficult time" came to Australia, the Australian side will be very welcome.
