This depends on the technical data analysis of the two black boxes, so further scientific investigation is needed to find out the cause of the accident.
-
It should only be a few days, and now the data of the black box has begun to be analyzed, and if the black box is not broken, it may be possible to understand the truth of some things in a few days.
-
It is not far from finding out the cause of the accident, and now a professional organization in Beijing is deciphering the data in the two black boxes, combined with the wreckage of the plane, I believe that the truth will soon be known.

The crash of the China Eastern Airlines passenger plane happened very suddenly, and the search and rescue personnel also started the search and rescue work after arriving at the scene, and found two black boxes on the plane at the scene, which was very close to finding out the cause of the accident. The two black boxes were safely delivered to Beijing, where they will be analyzed by a professional organization. The information in the black box is very important, and only when the black box is found can the specific cause of the accident be understood.
However, because the plane accident was very serious, the black box was also damaged, and the black box needed to be repaired while deciphering the information in the black box. If you want to find out the specific cause of the accident, it may take a little longer, about a month to two months, because it is also very difficult to repair the data loss in the black box. <>
The black box records the conversations of the flight personnel, as well as the communication between the ground air traffic control and the pilot, and all the sounds in the cabin are recorded. Based on these sounds, it is possible to know whether there was some abnormal situation in the pilot during the flight at that time. Only by integrating the data from the two black boxes can we understand the situation of the pilot at that time, which is also to restore the real situation of the accident.
The state of the second black box and the first black box is very close, and the data storage is relatively intact, but because the appearance has been seriously impacted, the bottom plate battery box has also fallen off. During the search, the orange fragments in the soil were also the remains of the black box, and the data in the black box could only be read after repair. If the chip of the black box is also damaged, the repair time will be longer.
Moreover, the division of labor between the two black boxes will also be different, so the data in the black box plays a very important role in the investigation of this accident. Because the data in the black box is very important, if the damage is made more serious during the repair process, some important information in the black box may be lost.

Black box. It is mainly divided into flight data recorder and cockpit voice recorder, the former mainly records 60 important data such as speed, attitude, and wind force before the accident. Or the equivalent of a voice recorder, which records all conversations and other sounds in the cabin, usually only the first 30 minutes of recording.
Professionals regularly collect this data to find out if the aircraft is faulty, and if the aircraft has an accident, the retained data can be used to simulate the plane crash scenario.
How were the two black boxes found?
After the accident, investigators drew a key search area at the scene according to the impact situation, and the first black box searched relatively smoothly, and it was found after searching for about two days in the core area. It is relatively difficult to find the second black box, which is logically installed at the tail end, and the distance between the two will not be too far after landing, but the firefighters have been looking for a long time in the vicinity but have not found it. Later, the experts went to analyze the posture of the plane when it landed, and judged that the second black box should be on the left hillside, and sure enough, they dug rice into the ground in the area and found the second black box.
How are the two black boxes damaged?
The two black boxes found were seriously damaged, and under the violent impact, only one cylinder was left in the black box, and the base was gone, and now it has been sent to a professional laboratory in Beijing to prepare for decoding. The black box is inspected in detail before decoding, which can take several days or a month, depending on the damage.
What remains to be done after the black box is found?
In order to accurately analyze the cause of the accident, the staff must collect the wreckage of the aircraft that can be collected, as well as collect the description of the plane crash seen by witnesses, and then compare it with the plane crash scene taken by the surveillance. Not a single detail can be missed, and it has now been confirmed that there are no survivors of the plane, but the search is still ongoing at the scene, just for fear of missing something.

The black box of the aircraft data recorder is specially designed to record various data in the flight, such as the flight time, speed, altitude, skewness of the aircraft rudder surface, engine speed, temperature, etc., and the black box of the pilot's language recorder, which records the speech between the pilot and the pilot and the passengers and flight attendants in the cockpit.
-
Conversations and other sounds in the cabin are stored, data on the flight of the aircraft, flight status of the aircraft, scenes of accidents on the plane, and conversations with the crew in the cabin are all stored in the black box.
-
The messages inside the plane before the crash and the conversations of the plane are stored. The data in the plane, the flight record in the plane, and some exchanges and recordings in the plane.
-
There are recordings of the cockpit, flight data records, various mechanical instrument data of the aircraft, and some ** in the cabin, which can be used to understand more about the condition of the aircraft, which is very important.
-
The second black box of the crashed China Eastern Airlines plane was found at around 9:20 a.m. on March 27This black box records flight data for a period of time before the plane crash
The flight data includes a lot of referencesThe number of aircraft will be recorded firstFlight speedThere are two kinds of atmosphere for the flight data of the aircraft: one is the relative air velocity; One is ground speed, which is the speed of the aircraft relative to the ground as recorded by GPS. These two speeds can calculate the wind speed and direction when flying.
The plane's will also be recordedFlight angle, including heading angle, pitch angle. The heading angle is recorded by the heading gyroscope, when the aircraft turns or tilts at a certain angle, the gyro rotor will stabilize in one direction, and the heading scale on the instrument will indicate the angle at which the aircraft turns. The pitch angle refers to the direction in which the nose of the aircraft is facing up or down during flight.
It will also be recordedThe position of the aircraft elevatorset,The position of the ruddersWait a minute. In addition, various operating instructions given to the aircraft by the operator in the cockpit are also recorded.
Therefore, in the absence of more information after a plane crash, the black box is a very important data recording memory, and it is also one of the most important tasks at the search site in addition to searching for and rescuing survivors. As a very important memory for recording data, the black box is generally placed on the tail of the aircraft, and in case of an accident on the aircraft, the black box will be less impacted. And in order to make it easier to find the black box after an accident, the black box is generally painted in a more eye-catching color, usually orange-red.
The reason why the black box is called "black box" is that after an accident, many recorders were burned black by the fire at the accident site, so they are called "black" boxes, but they are actually orange-red.
The two black boxes in this accident were hit by the downward impact force of the plane to a relatively distant place, although a mountain fire was caused in the core area of the crash, but the black boxes did not burn, and they were still orange when they were found. However, the appearance is seriously damaged, and it is hoped that the data storage inside is not damaged, which can provide effective information for the identification of the cause of the accident.
-
It records various data of the aircraft during the flight, including flight altitude, flight speed, aircraft time, etc., which can help the staff better analyze the operation status of the aircraft and better restore the truth.
-
Important parameters such as the flight data of the aircraft, the duration of the flight, the vertical speed, the operation of the crew, the number of steering wheel rods, etc., were recorded, and these parameters were important to investigate the cause of the plane crash.

<> the first black box of the China Eastern Airlines crash has been found, how long do we have to wait for the investigation report? At present, it is very difficult to find and rescue MU5735, and at the same time, the plane hit the ground unusually violently, and it is very difficult to find another black box. Of course, the analysis of the cause of the accident does not rely entirely on the black box, there are also the regulatory data of the air traffic control agency, the status of the aircraft landing, the analysis of the current situation of the plane hitting the ground, etc., in short, there are a variety of references to the analysis of the cause of the accident, as long as these references are consistent, the cause of the plane crash can be basically clarified.
If the black box is found and the data is complete, an accident investigation report can be issued within a month, and the public will be aware and concerned.
There are two black boxes on the plane, one to record the cockpit voice and the other to record flight data, and if one of them is damaged, it will make it difficult to determine the cause of the accident, and the time will be extended by one to two months. If all of them are damaged, they will be judged entirely by external data, and the cause of the accident should be disputed, and it may take two months to six months to report it, or even longer. At present, only a black box has been found, and it is a voice recorder to see the news, and the storage unit is relatively intact, but there is a certain amount of damage, and I don't know if there will be difficulties in data extraction.
Another black box flight data recorder has not yet been found, and it can only provide more detailed data if it is found. As for the time when the official investigation report will come out, you can refer to the time required for the investigation report of the most recent Yichun air crash.
The Yichun air crash occurred at 21:00 on August 24, 2010, and the official issuance of the investigation report was on June 29, 2012, with an interval of 22 months, nearly two years. The full text of the official investigation report can be seen on the official website of **, and the specific content will not be repeated here. At present, it is still hoped to find a second black box as soon as possible and do a good job of data extraction and analysis for detailed investigation and analysis.
The investigation report will involve the basic situation of the flight, the course of the incident, the cause and characterization of the incident, the handling of responsibilities and follow-up rectification suggestions, and it will take a long time to investigate and demonstrate. Wait patiently, believe **, believe that the investigation team will give a complete investigation report and a detailed cause of the accident.
-
We need to wait for half a month to a month for the investigation report, because extracting the content is a very complex process, and there are many problems that need to be solved when extracting the content, and the chip of the black box also needs to be tested.
-
The investigation report needs to wait for about 3 to 5 days, and it is necessary to repair the data of the black box and understand the damage of the black box, which generally takes about a week.
-
We have to wait days or even months for the investigation report to see the severity of the plane crash.

The second black box of the China Eastern Airlines flight accident passenger plane has been found, and finding the black box does not mean that the truth of the crash will be found. The reason for this is because the two black boxes on the crashed plane of China Eastern Airlines have been damaged to varying degrees, and it is not known whether they can be repaired, and whether they can be completely deciphered and exported data is unknown! If the black box of the China Eastern Airlines passenger plane is only damaged in appearance, but the built-in chip is not damaged, and the technical engineers can crack it smoothly, then, with the support of key data, the truth of the crash should be found out as soon as possible!
Generally speaking, if the built-in chip in the black box is not destroyed, it will take ten to fifteen days to decipher and export the data! If the data of the black box is successfully deciphered, it is customary for the preliminary report of the plane crash to be submitted within 30 working days! In other words, the cause of the China Eastern Airlines passenger plane crash can be concluded within 30 working days!
Now the relevant departments are going all out to find the truth, the black box data is very important, the daily maintenance records of the aircraft and the wreckage of the aircraft found after the crash are also very important. Combining all the data, I believe that the truth of the crash of the China Eastern Airlines passenger plane will be restored.
Confidence. When the first black box was found, it strengthened everyone's confidence that they could learn the truth about the crash of the China Eastern Airlines passenger plane! When the second black box was found, the public felt that it was only a matter of time before the truth about the crash of the China Eastern Airlines passenger plane was ascertained!
Indeed, a cabin sound recorder, a recorder that records the data of various key components in the flight process of the aircraft, as long as it can be deciphered, I believe it can point to the truth!
Wish. The crash of the China Eastern Airlines passenger plane has touched everyone's hearts, and the first seven memorials for the victims have passed, and the search and rescue personnel are still working hard to search for the wreckage of the wrecked plane, in order to find out the truth when there is more data support! Now the wreckage has been transported to a fixed location, and the relevant personnel are fighting the "wrecked plane" in order to restore the truth to the greatest extent!
The second black box of the China Eastern Airlines flight accident passenger plane has been found, and I hope that the two black boxes are not damaged, and I hope that the results of the investigation can be released as soon as possible!
Personally, I feel that as a family member, while grieving, we should also wait for the relevant departments to give me a reasonable explanation. >>>More
China Eastern Airlines responded that a bird flew out of the cabin during the flight of the passenger plane, and the bird should have entered the cabin when the plane was waiting to fly on the ground! The senior captain said that it was impossible for the bird to enter the cabin while the plane was flying! Because the whole plane is completely closed when the plane is flying, the cabin pressure must be adjusted! >>>More
The black box of the wrecked airliner in India has been found, has the cause of the crash been found? Not yet. According to India's New Delhi TV report, the "black box" of the passenger plane that crashed at Kozhikode International Airport in Kerala, southern India, on the 7th has been found. >>>More
I am from the special brigade of the Airborne Forces, the reason is very simple, passenger planes and transport planes transport paratroopers are different, paratroopers pay attention to rapid landing, focusing on actual combat, the slower you want to descend, the more paratroopers will be killed by the enemy on the ground, and you will know after watching the Normandy landing! In order to fly long distances and not be disturbed by the weather and air currents in one direction, it is generally necessary to pull up the altitude after take-off, once the height of the crash from the ground is too high, if the door is opened to parachute, then the strong air pressure and air flow will tear the parachute, which endangers the safety of passengers, and passengers generally will not be like paratroopers have parachute training, and there will definitely be an accident if you jump rashly, after all, parachuting is not bungee jumping! I remember the Sichuan earthquake relief, our special brigade (the only special brigade of the Air Force) in Wenchuan had 15 members of the parachute jump, in fact, they all wrote suicide notes, because there is no country in the world paratroopers jumped so high, they jumped, just a small area without clouds, the rest of us because of the cloud received orders did not continue to jump, at the end of last year I was discharged, take off this military uniform, we are still special combat members, one day to fight Taiwan we have nothing else, Let the blood of the Airborne Forces be scattered all over Taiwan!! >>>More
I think it was an operational problem, because the data showed that the plane was landing at a high speed, and various factors confirmed that there was no quality problem with the aircraft.
