How did MH370 fly to the Indian Ocean

Because after losing contact, it flew to the Indian Ocean.

MH370 flight is a Malaysia Airlines flight flying from Kuala Lumpur International Airport (KLIA) to Beijing Capital International Airport.

Flight MH370 carried 227 passengers (including 153 from Chinese mainland and 1 from Taiwan) and 12 crew members. 328 days after MH370 went missing, the Malaysian side confirmed that it was wrecked, and all the people on board were killed.

On January 29, the 328th day since the disappearance of Malaysia Airlines MH370, the Director General of the Civil Aviation Authority of Malaysia Azharuddin officially announced the crash of MH370 and presumed that all 239 passengers and crew members on board the passenger plane had been killed. The Malaysian side also published the full text of the statement on the MH370 official website, which contains 31 points related to the investigation of the accident, search efforts, and compensation for families.

Not found in the Indian Ocean.

On July 29, 2015, a piece of wreckage about 2 meters long was found off the coast of Reunion Island, France, in the Indian Ocean, with the number BB670 on it, which was suspected to belong to the wing fragment of flight MH370. Later, experts identified the wreckage as belonging to a Boeing 777, which is the same type as Malaysia Airlines flight MH370.

On the afternoon of Wednesday, the 5th local time, experts from France and Malaysia arrived at an experimental center in southern France to begin the identification of the flaperon wreckage suspected to belong to the MH370 passenger aircraft. Hours, Malaysian Prime Minister Najib Razak announced that the wreckage of the plane found off the coast of French Reunion Island was indeed part of the missing Malaysian flight MH370.

On March 8, 2014, Malaysia Airlines Flight 370 (** sharing China Southern Airlines Flight Z748), a total of 239 people left Kuala Lumpur International Airport Terminal M at 0:43 a.m., originally scheduled to arrive at Beijing Capital International Airport at 6:30, but disappeared from the radar two hours later, and lost contact with the Malaysian Kuala Lumpur (Subang) Air Traffic Control Center, the last location of the plane before disappearance was at the junction of Malaysia and Vietnam, latitude and longitude was 06°55 north latitude 15 103°34 43 E, but no wreckage was found at this location.

The flight is operated by a Boeing 777-200ER (registration number: 9M-MRO).

On April 21, 2014, Malaysia Airlines flight MH192 made a safe forced landing at Kuala Lumpur International Airport. The flight was forced to turn back due to a landing gear failure.

On July 17, 2014, it was reported that another Malaysia Airlines passenger plane, MH17, was in distress. Malaysia Airlines MH17 was shot down by a Russian-made BUK missile on the territory of Ukraine, killing 298 people.

Malaysia Airlines MH370 to date (not found.

1.The first time the aircraft deviated from its course, it was operated by a human being, not by an autopilot system. The last two turns in the south of Penang and the north of Mekar are uncertain whether they were manually operated or autonomous.

2.The radio and call messages from the pilot and co-pilot showed no signs of anxiety or stress, and records from aircraft maintenance personnel showed that the aircraft was in good condition and that there were no records of any malfunctions or defects that led to the disappearance of the aircraft.

3.It is not possible to determine whether the aircraft was flown by anyone other than the pilot, and the possibility of illegal interference by third parties cannot be ruled out. But according to military records, there is no evidence that the rapid changes in flight altitude and speed were caused by the MH370 deliberately evading radar.

4.Pilot Zaharia had no conflicts with family or friends, showed no symptoms of social isolation, self-contempt, no alcohol or drug abuse, no changes in habits or interests, no signs of anxiety or stress detected from the recordings, and no significant behavioral abnormalities were detected in the surveillance footage. "He is a very competent pilot with an almost flawless flight record and is able to handle the stress of the job very well.

Kok so Chon said.

5.The co-pilot also had no clear motive for changing the course of the aircraft.

6.There is no evidence that the aircraft was remotely controlled or taken over, and the technology has not yet been implemented on commercial aircraft.

7.A mechanical fault cannot be ruled out, but it is more likely that the aircraft's communications, tracking, and emergency SOS systems were deliberately disabled.

8.Of the 27 wreckage collected so far, only three have been identified as coming from MH370s, and the rest are only "highly likely from Boeing 777 aircraft." The wreckage showed that the aircraft was in normal flight condition at the time of the overboard.

The Malaysia Airlines MH370 crash killed 239 people, with 227 passengers and 12 crew members, 154 of whom were Chinese, found only trivial fragments on a small island in the Indian Ocean in August 2015.

March 8 Malaysia flight disappearance incident At 2:40 a.m. on March 8, 2014, Malaysia Airlines said it had lost contact with a Boeing 777-200 aircraft with 239 people on board, flight number MH370, which was scheduled to fly from Kuala Lumpur to Beijing. The aircraft was due to arrive in Beijing at 6:30 a.m. Beijing time on March 8, 2014, and lost contact with the control center at 2:40 a.m. local time in Malaysia on March 8, 2014.

Malaysia Airlines has activated a rescue and liaison mechanism to locate the aircraft.

At 10 p.m. on March 24, 2014, Malaysian Prime Minister Najib Razak announced in Kuala Lumpur that Malaysia Airlines flight MH370 had crashed in the southern Indian Ocean, and no one on board survived. On June 8, the families of some of the missing passengers of Malaysia Airlines MH370 were prepared to spend a lot of money to encourage "informants" to come forward and provide effective clues in order to solve the mystery of the plane's disappearance.

On 29 January 2015, the Malaysian Civil Aviation Authority announced that Malaysia Airlines Flight 370 had crashed, presumed that all 239 passengers and crew on board had been killed.

On 30 January 2015, Malaysia's Transport Minister Liew Chung Lai said that Malaysia would supervise and ensure that Malaysia Airlines would pay compensation to the families of the passengers and crew of the MH370 passenger aircraft.

On the evening of February 4, 2015, the China Insurance Regulatory Commission issued a notice to all insurance regulatory bureaus, the Insurance Association of China and insurance companies, requiring them to do a good job in the insurance claims service for passengers on flight MH370.

On February 24, 2015, Malaysian Transport Minister Liew Chung Lai said that Malaysia Airlines will hold a memorial service for the passengers and crew on board on March 8, the first anniversary of the MH370 crash.

On 8 March 2015, Malaysia Airlines released its 584-page interim report.

The wreckage of the plane found on July 29, 2015 on the French island of Reunion in the Indian Ocean belonged to the Malaysia Airlines MH370 passenger plane that went missing from Kuala Lumpur to Beijing on March 8 last year (2014), and the wreckage of MH370 flight was found for the first time after being missing for more than 500 days and nights.

11 degrees 53'34''N 103 degrees 51'39''e, the coordinates I found on Google Maps, is a wrecked plane covered in greenery, I don't know if it's Malaysia Airlines MH370. I have measured the size, the wing is 61 meters, the fuselage is 95 meters broken into 2 sections, and the original aircraft is 63 meters.

Not yet, but the floating debris on the surface of the sea is most likely debris from Malaysia Airlines.

According to the information from a press conference held in Malaysia on March 15 regarding the disappearance of the MH370 passenger plane, when the passenger plane made contact with the last signal of the satellite, it may be in two red arcs in the picture. The first is in the direction of Kazakhstan to Turkmenistan and extends south to Thailand; The other is from Indonesia, which extends south to the Indian Ocean. So how should this judgment be understood?

There is a satellite above sea level at an altitude of 35,800 km above sea level over the Indian Ocean, which is judged to be a geostationary geostationary satellite according to its altitude, which means that it is always hovering here relative to the terrestrial reference frame.

The first constraint:

According to reports, at 8:11 on March 8, the satellite made a signal contact with MH370, so theoretically, the distance between the satellite and the aircraft can be calculated according to the reentry time of the signal between the satellite and the aircraft multiplied by the speed of signal propagation (the speed of light) and divided by 2, and then a cone with the satellite as the apex is drawn at this distance, and the intersection of the cone and the earth's surface is a circle, and the passenger plane is confined to this circle at 8:11 (compared to the height of the synchronous satellite, The height of the airliner is negligible).

Second constraint:

On the other hand, the last radar contact with MH370 is also marked in the map at 2:40. Based on the amount of fuel and the speed of the aircraft, it is possible to roughly determine the maximum distance it can fly, so that the left part of the circle drawn by the satellite can be erased, and only the right part remains.

The third constraint:

The middle part of the arc on the right is located from Indonesia to Myanmar, and this part of the area is in the radar coverage area, which also basically excludes the possibility that it was in this arc at that time and can be erased from the arc.

Therefore, combining the above three constraints, only the two red arc areas in the figure remain. The meaning of the diagram is only: at 8:11 on March 8, the passenger plane was at a certain point in the two arcs, as for the specific point, according to the available data, it is impossible to judge, and the subsequent destination is unknown.

That's what this diagram can tell us.

The suspected wreckage found in Australia is at the southern end of this arc, so it is judged that Malaysia Airlines MH370 may have flown here.

The cause is still under investigation, and the research process is as follows:

Malaysian officials have announced the basic research and judgment process from relevant British agencies to determine that MH370 fell into the southern Indian Ocean. Experts from the British Aviation Accident Investigation Agency (AAIB) and the International Maritime Satellite Organisation (Inmarsat) and the Malaysian side will explain the relevant content to the families in detail.

Authorities determined that the plane was heading for the southern Indian Ocean by detecting pulse frequency shifts in the "hand shake" signal between the aircraft and the satellite, and between the satellite and the ground receiving station. This new method uses the "Doppler contribution", a theory derived from the Austrian physicist Doppler. In a nutshell, the phenomenon of a change in frequency is felt by the observer due to the relative motion between the source of the wave emitting the sound or electronic signal and the observer (receiver).

This change is called an "offset" and can also be measured in the unit of "Hz" by the instrument.

In the MH370 case, the relative position between the communication satellite and the earth is fixed, and the relative position of the MH370 aircraft will change relative to the satellite when it moves north or south over the Strait of Malacca. When the aircraft transmits the "handshake signal" at different positions, and when it is transmitted to the ground receiving station by satellite, a small difference between the signal pulse intensity and the preset strength will occur, and the speed and course of the aircraft can be judged by comparing the simulated scenes.

Inmarsat has announced that after MH370 turned off the Aviation Response System (ACARS) and the turnaround, they received at least six times that the aircraft had "shaken hands" with the satellite via the satellite data link, basically at one-hour intervals. A vice president of the agency said that this was because the airlines did not purchase information services that continuously track the trajectory of aircraft. According to Malaysia, the agency and the AAIB also conducted simulation scenario experiments based on data from six Boeing 777 aircraft, and finally determined that the burst frequency offset received by the satellite receiving station was different when the MH370 flew in different directions.

Relevant materials show that it is through the satellite signal ground receiving station in Australia that the heading and speed of the aircraft are offset by pulse frequency. The graphs released by the Malaysian side show that the curves derived from this analysis show that the data on the frequency shift of the signal pulse is highly consistent with the data on the flight to the southern Indian Ocean in the simulated scenario. If the plane is flying to the northern route, the offset calculated at the last signal "handshake" is about 50 Hz lower.

Malaysian officials believe that the last time the plane tried to "shake hands" with the satellite was at 0:11 UTC (8:11 Beijing time), and no relevant signals were received after 0:15. With no land to land, the Malaysian side believes that the plane has crashed into the southern Indian Ocean.
