Since the 20xx. 03.21 China Eastern Airlines plane crash, the question that everyone has been concerned about whether the black box has been found has been answered today. With the continuous efforts of search and rescue personnel, the black box was found. Next, let's find out what is the connection between the two black boxes.
At about 9:20 a.m. on the 27th, the fire rescuers searched deeply in the key area designated by the technical team, and manually excavated an orange cylindrical object, which was immediately taken out by the civil aviation accident investigators who investigated the site and confirmed as the storage unit of the flight data recorder. It was found to be located on the slope about 40 meters east of the main impact point and about 1.5 meters below the surface. After inspection, other parts of the recorder were seriously damaged, and the appearance of the data storage unit was relatively intact. The flight data recorder found on the morning of 27th has been sent back to Beijing by 13:00 flight. At present, the
black box has been sent to a professional laboratory for decoding.
There are two black boxes in the crashed passenger plane, one of which, the cockpit voice recorder, was found on the 23rd.
What is the connection between the two black boxes? How does it affect the investigation?
Now that both black boxes have been found, what is the connection between the recorded data? What impact does this have on the comprehensive investigation of the cause of the accident? The division of labor between the two black boxes is different: cabin voice + flight data
Although both black boxes look orange working devices, their shapes are very similar. However, the division of labor is different. The first black box usually records the voice in the cabin, and records all the sounds in the cabin, including the dialogue between pilots, the communication between pilots and ground air traffic control, and all the background sounds in the cabin. For example, the alarm sound of instruments and the abnormal sound of other equipment. The second flight recorder usually records flight data, and it will collect all data parameters of all key systems and key equipment
during flight. For example, the working condition of the engine, the main control surfaces of the aircraft (such as the position of the throttle and the action of the joystick), the speed and heading of the aircraft, Height, addition and subtraction The rate of change of speed.
The combination of two black box data is more conducive to restoring the accident state and finding the cause These data are particularly important for future investigations. First of all, the sound data collection can restore the feedback of the pilot's flight state at that time and the communication of some control intentions in time. Secondly, the second black box can reproduce the technical state and flight state of the aircraft at that time from the perspective of data. Therefore, the two black boxes can be combined to infer whether the pilot's flight evaluation at that time is in line with the facts, whether their intention for flight operation has been realized, and whether this executed intention has received flight attitude feedback. Once the two data are combined, they can restore the scene of the accident and provide the most powerful evidence.
I hope this black box can restore the situation as soon as
possible.。
