Why did the plane crash in the southern Indian Ocean

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.

Agencies do this by discovering the "handshake signal" between aircraft and satellites, and between satellites and ground receiving stations

shake) determined that the aircraft was heading in the direction of the southern Indian Ocean. This new method uses the "Doppler effect" (Doppler

contribution), which is 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. Malaysia said that the agency and AAIB also conducted simulation scenario experiments with data from six Boeing 777 aircraft, and finally determined that when MH370 flew in different directions, the pulse frequency shift received by the satellite receiving station (burst).

frequency offset) is different.

The material shows that the heading and speed of the aircraft were compared with a pulse frequency offset by a satellite signal ground receiving station in Australia (see Figure 2). The graphs released by the Malaysian side show that the curves derived from this analysis (see Figure 1) show that the data on the frequency shift of the signal pulse is in good agreement 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.

Why Malaysia Airlines MH370 headed south to the southern Indian Ocean, investigators may never be able to find out the truth.

The current assumption is that the flight will fly south and further to the end of the Southern Air Corridor. The source said. The air corridor refers to the search area from the western side of Indonesia to the waters of the Indian Ocean west of Australia.

The current assumption is that the aircraft flew south and to the southern end of the Southern Corridor. The source, who spoke on condition of anonymity, said.

This view is based on the fact that the countries along the Northern Corridor did not detect the flight entering its airspace and that no wreckage was found in the northern part of the Southern Corridor.

Last week, an American evaluator concluded that the plane most likely ran out of fuel and crashed into the southern Indian Ocean — the wildest and deepest body of water on the planet. If that is the case, then there is a good chance that we will never find the plane, and investigators will never find out what happened on the plane.

The reason why Malaysia Airlines MH370 flies south to the southern Indian Ocean may be to avoid the highly militarized zone.

According to the U.S. **March 18**, the current military ** and former military ** said that if the missing Malaysia Airlines flight lost contact with ground controllers on the 8th and flew north over the Asian continent, it would be difficult for it to avoid the surveillance of Chinese, Indian or American radars.

Experts familiar with the radar systems used in the region say a Boeing 777 is unlikely to go unnoticed by Chinese and Indian air defenses and U.S. forces in Afghanistan.

China was the original destination of the missing flight. China is protected by military radars deployed at high altitudes on the border and even inland.

The border between India and Pakistan is a highly militarized area. Radar experts and the Indian military ** believe that it is impossible for a passenger plane to pass through the area without being noticed.

Further to the northwest, the US Air Force deployed radars in Afghanistan to protect its air bases.

Why did Malaysia Airlines MH370 fly south to the southern Indian Ocean, experts say that the plane's trajectory before its disappearance has traces of careful planning.

From the series of actions of the captain that were reported, it can be seen that the captain may have been involved. It is an obvious move why flights turned around immediately when the air traffic control of the two countries first took over. In addition, the plane also took the action of evading the radar, and third, exceeding the altitude of normal flight, it would cause the passengers to lack oxygen, be slow to react, and turn off the transponder of the foreign communication station.

Why can't the satellites of so many countries find the plane, because if the body sinks to the bottom of the sea relatively intact, there will be no debris on the surface of the sea in the short term, and of course the satellites will not be able to find it. However, more than 10 days have passed, and the ocean is several thousand meters deep and the pressure is very high, which will crush the relatively fragile parts such as the joints of the fuselage, and some wreckage may surface. But whether this is the case depends on satellite data.

It is normal for military aircraft to crash, and the air forces of various countries crash planes every year, but the Indian Air Force has the highest accident rate among the air forces of various countries. Mainly for technical reasons.

The Indian Air Force has had a cumulative 20 crashes of military aircraft in the last three financial years. Of these, six crashed in FY 2012-13 (April 1, 2012 to March 31, 2013), six in FY 2013-14, eight in FY 2014-15, and no crashes occurred in FY 2015-16 as of April 23. These crashes have cumulatively caused losses of Rs billion.

Each accident and accident was thoroughly investigated by a specialized investigation team, the cause was identified and the recommendations of the investigation team were implemented by the Indian Air Force. The results of the investigation revealed that the main factors leading to these accidents were human error and technical deficiencies.

India's air force is known as "made in all countries," and there are many and miscellaneous types of fighters, many of which are imported from Russia, Europe, and other countries. Many of these aircraft are older. However, India's aviation technology is not good, its logistical support capability is limited, and the flight losses of aircraft in ordinary times are relatively large, and the slightest negligence on the part of technical personnel can cause a serious disaster.

This is the main reason for the high accident rate of the Indian Air Force.

From a corner of the country, the crash of India's military plane is actually a fragile manifestation of India's entire military strength.

1. The reliability of Indian fighters is low: India's military strength depends on buying, from 2007 to 2013, India is the world's largest importer, accounting for nearly 10% of the total imports at the same stage. It wasn't until last year (2014) that Saudi Arabia came out on top.

To make a horizontal comparison, India's 14-year** imports are more than three times that of China and Pakistan. In the early stage, India mainly purchased Soviet and Russian fighters, which were not as reliable as American aircraft, and the main military aircraft in service were relatively old, which increased the crash rate.

2. The ergonomics and environmental adaptation of Soviet Russian fighters are designed with reference to the Caucasian race, and they are quite unaccustomed to the water and soil of India, which is located in South Asia.

3. Backwardness of the military industry: India's air support and aircraft support capabilities are quite low, and there are huge defects in the use, maintenance, and maintenance of imported military aircraft, and there is no core technology.

4. India's very corrupt social environment: Corruption in India is very serious and has penetrated into all walks of life. Many pilots' licenses can be obtained through bribery, and although military pilots are much stricter, this kind of general climate and atmosphere will inevitably lead to uneven quality of pilots and insufficient hard work.

Have you ever seen a huge investment in nuclear submarines without nuclear power, and have you ever seen an 85% project rebate, all of which are Ah San's patents.

5. The quality of military personnel is low.

But India is not bad, military aircraft crashes in various countries are common, and India is only slightly more probable.

Most of India's military aircraft are aging, aircraft maintenance technology is inefficient, and some Indian aircraft operators may be operating improperly, resulting in the crash of Indian military aircraft.

Quite simply, because their flight training intensity is dozens of times that of our China!!

Because they buy obsolete products from the former Soviet Union, the quality is not up to par, and they are not well maintained, the life span is limited, there are many failures, and there are many accidents, hehe.

Because many Indian fighters are imported from Russia and the United States, domestic fighters have been under development. So there are more accidents.

The number of flights is too high, coupled with the weakness of the defense industry and the dependence on imports, which makes it difficult for logistics to keep up. There will always be planes that break down.

Since 1966, a total of 872 MiG-21, MiG-23, MiG-27 and MiG-29 MiG-29 fighters have been in service with the Indian Air Force, and as of April 19, 2012, 482 MiGs have crashed, killing 171 pilots, 39 civilians, 8 ground staff and 1 crew member. India's MiG-21 also got its name "Widowmaker".

From 2008 to February 2013, in just five years, the Indian army crashed 55 fighters of various types, including 4 Russian-made Su-30 fighters, 2 French-made Mirage-2000 fighters and other advanced fighters, killing a total of 21 pilots. At its peak, in 2003, the Indian Air Force crashed 52 planes in just one year, an average of every week, and it firmly held the top spot in the crash rate of air force fighters in the world.

In 2011-2012, 13 aircraft were lost.

2012-2013 6 crashes.

In 2013-2014 6 aircraft were lost.

In 2014-2015, 5 aircraft crashed.

In addition to these crashes, 2 MiG-17*** aircraft of the Indian Air Force were destroyed.

The trade-off between politics and humanity will one day come to light.

There's a lot of talk upstairs, but I personally feel like there's a conspiracy in it. Now just the truth!
