The electronic flight recorder, also known as the black box, is divided into two parts: FDR and CVR.
FDR, flight data recorder, records all the electronic data of the aircraft during flight.
CVR, the cockpit voice recorder, records any sound that occurs on the flight.
After listening to the last 30-second cockpit audio of JAL JL917, Zhuo Huan immediately turned his focus back to FDR. He wanted to check the flight data before the crash.
Su Fei retrieved the flight data.
Zhuo Huan: "Look at the last 30 seconds first."
Su Fei: "Okay, come on."
The moment the Enter key was pressed, dense data curves immediately filled the entire computer screen. In the eyes of laymen, this graph is intricate, with all kinds of data crowded together, making it difficult to understand.
Zhuo Huan saw it very quickly.
He could almost see ten lines at a glance, and kept pulling down the progress bar. From the countdown of thirty seconds, he saw the countdown of sixteen seconds in the blink of an eye.
When he saw the sixteen seconds before the crash, his eyes stopped.
Zhuo Huan: "Enlarge this section, project it on the screen, and only capture these two seconds."
Su Fei got the order and projected the 16 to 14 second data map on the screen in a few clicks.
Zhuo Huan: "The audio of the same time period is also put on it to intercept the conversation in the cockpit."
"Okay!"
One speaks quickly, one does quickly.
The staff of other investigation agencies present were still at a loss, but Su Fei had followed Zhuo Huan's instructions and projected all the required data and audio onto the big screen.
Only then did they discover what kind of monster this strange boy in UAAG, who seemed to be underage, was.
He wore skull stud earrings, and the tips of his hair still had a touch of green that hadn't quite faded.
Has a bizarre aesthetic and a punk look.
But on top of that - he's a genius.
Zhuo Huan asked Su Fei to overlay the flight data and audio, and he pressed the play button.
"Getting ready to deploy the landing gear... wait, I suddenly lost thrust. 』
The penultimate 16th second before the crash, to the penultimate 14th second.
The co-pilot Maeda Shosuke let out an exclamation of astonishment. He was surprised to find that he had lost the thrust of the engine.
His reaction was extremely fast, and the flight data showed that 16 seconds before the crash, all four engines suddenly shut down at the same time. And just two seconds later, he discovered the anomaly.
Zhuo Huan: "Play it again."
Su Fei obeyed.
Zhuo Huan: "Play it again."
Su Fei pressed the play button again.
"Play it again."
After repeating it seven times in a row, the man closed his eyes and listened carefully to every sound coming from the stereo.
His behavior made everyone in the audience incomprehensible, but they all followed this man and listened over and over again.
After the seventh round, he suddenly opened his eyes: "Play the last thirty seconds of audio from beginning to end again."
Su Fei: "...OK."
"Make sure the throttle is tightened. 』
『It is confirmed that the throttle is tightened. 』
"Flaps open 30 degrees. 』
…
"Ah, get up, pull up! 』
"GLIDE SLOPE! GLIDE SLOPE! GLIDE SLOPE! 』
"Ah, it's about to hit! 』
"boom-"
After the harsh and ear-piercing impact, there was the sound of zizzing electricity. Soon, the black box stopped working, and it finished recording the mission it needed to undertake.
Zhuohuan: "Listen again."
Su Fei: "OK!"
Listening to it over and over again, at the same time, Su Fei continued to process the relevant data of the black box.
Now what they hear and see is only the last 30 seconds. This black box has completely recorded all the data of the 30 minutes before the crash.
Zhuo Huan: "Has the data of the last ten minutes been processed?"
Su Fei: "Eh? Not yet, it took only five minutes to deal with it."
"Listen for five minutes first."
Su Fei: "..."
This horse riding is definitely exploiting child labor, absolutely!
He scolded the big devil 10,000 times in his heart, the punk boy pursed his mouth, and projected the five-minute data he had just processed on the big screen for everyone to observe and analyze.
Aircraft accident investigations are bound to be boring, and it is impossible to get results quickly.
Investigators from other agencies were busy with their own affairs, and only the people from UAAG were still here, accompanying Zhuohuan to listen to the voice in the black box over and over again.
"It's not right."
Fu Cheng suddenly raised his head and looked at Zhuo Huan.
Lifting his right hand to cover his lips, Zhuo Huan lowered his head and looked at the ground, his long and narrow eyebrows were tightly knit into a ball.
Old Joseph: "Reid, what's wrong. Judging from the flight data curve, there is nothing wrong with it, except that four engines suddenly shut down at 16 seconds from the countdown. Before that, the aircraft data was normal."
Zhuo Huan didn't answer. He closed his eyes, and at this time the audio started a new round of playback. He listened carefully, and suddenly opened his eyes.
"The sound is too muffled."
"Ah?" Everyone looked at each other, and they all saw the confusion in each other's eyes.
Fucheng was also at a loss.
Too boring
What sound is too muffled
A conversation between three pilots in the cockpit
Zhuo Huan raised his head slowly, and old Joseph was sitting in front of him, so he met old Joseph's eyes at first sight. But after pausing for a moment, he turned his gaze to the black-haired young man standing beside him.
After the two looked at each other, Zhuo Huan said, "You used to be a carrier-based aircraft pilot."
Fu Cheng shrank his eyes, and after a long time, he nodded: "Yes."
As soon as these words fell to the ground, there was an uproar in the audience, and Old Joseph whistled.
Su Fei jumped up from the chair directly: "Fuck, brother, aircraft carrier pilot? Are you so awesome?! Fuck the aircraft carrier!"
Fu Cheng glanced at him.
It is to fly the aircraft on the aircraft carrier, not the aircraft carrier.
But too lazy to correct him.
Zhuo Huan sat on the swivel chair, tapping lightly on the armrest of the chair with his right hand.
"Civilian airliners and military aircraft have different engine performances, and the engine vibrations caused by fuel are also different. But this difference is difficult for the human ear to distinguish. But carrier-based aircraft are different." Zhuohuan said, Looking at Fucheng with sharp eyes, "It is extremely difficult for the carrier-based aircraft to land, so the difference in engine noise and vibration can be directly observed by human ears at this time."
Fucheng looked calm: "Yes, the sound of the engine when the carrier-based aircraft lands is very different from other aircraft."
Zhuo Huan: "The engine noise of JL917 is different from the normal McFly F435."
A flash of inspiration flashed in Old Joseph's mind, and he said to Su Fei: "Quick, find a normal F435 engine sound track and listen to it."
Su Fei: "..."
All of you trampled on me as a child laborer!
Complaining in his heart, Su Fei still quickly found a normal engine sound track of F435 from the data network, and released it.
However, after listening.
Old Joseph: "... Is there a difference?"
Fu Cheng smiled and said, "I don't think so."
Su Fei raised his hand: "I don't think so either!"
After hearing what they said, Zhuo Huan let out a laugh from his nose, and he took a sip of coffee.
"Can't hear it, stack the tracks together, can't you tell it?"
Su Fei then overlaid the engine sound track of the normal F435 aircraft with the sound track of the Japan Airlines F435.
The moment the two audio tracks overlapped, Fu Cheng's lips moved, unable to hide his astonishment.
After a long silence.
Su Fei: "... You can hear this even when you are riding a horse, is it still a human being?"
The punk boy didn't deliberately lower his voice, and these words passed steadily into Zhuo Huan's ears.
It was rare for him not to pretend, but to tell the truth and explain: "Because this is Mai Fei's plane."
Old Joseph: "I know you used to be the chief designer of McFly, but you haven't participated in the design and improvement of F435."
Zhuo Huan's eyebrows moved: "Lina told you?"
Old Joseph: "Yes, did you participate in the design of F435?"
"No."
As soon as everyone breathed a sigh of relief, the Great Demon King said in a nonchalant tone, "But I have dismantled an F435."
"..."

Finland, Helsinki, Aviation Safety Agency.
Early in the morning, media reporters blocked the entrance of the Aviation Security Bureau.
The Finnish Ministry of Information and Information has prepared a conference room. At 9:50 am, media reporters entered the conference room, waiting for the press conference to start.
At ten o'clock sharp, the door of the conference room opened. A slender blonde woman in a red dress walked into the conference room. Her slender high heels made her legs straight and slender. She showed a generous and beautiful smile, stood in front of the rostrum, and spoke softly.
"Hi everyone, I'm Stephanie Comte, I belong to UAAG, a multinational aircraft accident investigation organization. Today I will be responsible for reporting to the public, UAAG's investigation progress on JAL JL917 air crash..."
After the half-hour task report, it was the media reporter's questioning session.
These seemingly dignified reporters in suits turned into sharp warriors holding sharp knives at this moment, attacking the French girl on the rostrum. It's a pity that everything was defeated by her elegant and perfect smile. Lina answered every question of the reporters with ease until the end of the press conference.
At noon, officials from the Finnish Aviation Safety Agency personally sent her away.
"Say hello to Mr. Comte for me."
Lina smiled and said, "I will definitely convey it to my father."
When getting on the bus, the blonde girl saw a decadent Asian man sitting on the stone at the entrance of the Aviation Security Bureau. He looked at the ground in despair, the suit on his body hadn't been changed for many days, it was wrinkled and dirty.
Lina watched for a long time, and the Finnish official followed her gaze.
"Oh, that's a survivor of an air crash. He came to us every day for the past few months and asked us to punish the co-pilot severely, saying that the co-pilot kidnapped the plane and caused the crash. But the co-pilot is dead, and we also If you don’t understand his needs, you can’t drive him away. Now that the truth is out, he should feel better, it’s not a human factor.” The official turned to look at Lina and said with a smile, “I hope Mr. Patrick can find out the truth sooner. .”
Lina: "I'll pass it on to Reid."
Find out the truth
Easier said than done.
They have just given up on a wrong path and seem to have found a new direction.
However, looking up from a distance, the road ahead is full of thorns, covered by black fog and thick clouds, with no end in sight.
It probably takes a miracle to find out the truth quickly.
But isn't Reid itself synonymous with miracles
The French girl smiled slightly, got in the car and left.
***
Investigate headquarters.
After the new direction of investigation came out, everyone fell into a new problem.
Old Joseph: "The engine rattling is indeed different, but from the flight data, this abnormality did not affect the normal operation of the engine. It can be speculated that the rattling is related to the cause of the accident, but what is the specific reason and where should we start? "
"Could it be related to the low-pressure turbine module?"
Old Joseph: "Low-pressure turbines of all four engines go wrong together?"
"Perhaps a fan module?"
Old Joseph shook his head: "I guess, maybe when the gas flows out of the tail nozzle, there is an abnormal noise... Eh, by the way, where are the Reid people?"
Going down the stairs to the first floor, Fucheng searched for a long time among the messy pile of machine parts, and finally saw the man.
Sitting at the top of the engineering ladder, he held a wrench and gently removed a cylindrical metal part from the engine. There were inevitably some stains on the white T-shirt, and even on the thin arms, there were also stains.
After removing the things, Zhuo Huan lowered his head and saw Fu Cheng.
Frowning, Zhuo Huan: "How long have you been watching?"
Fucheng: "Old Joseph and the others are discussing above, Mr. Zhuo, why don't you go."
"you?"
Fucheng: "..."
Fucheng: "Why don't you go?"
Zhuo Huan laughed.
With a leap, he jumped off the ladder.
Zhuo Huan: "I listened to them for half an hour."
Fu Cheng: "Huh?"
Zhuo Huan: "I still gained something, got some inspiration."
Fu Cheng: "For example?"
Zhuo Huan looked at him: "A thing that disappeared quietly after the crash has the power to damage four engines at the same time. This is what they concluded."
Fucheng: "..."
In particular, he wanted to say that Old Joseph and the others did not summarize these well-known things, and they also proposed many directions for investigation. Such as low-pressure turbine, fan module, tail nozzle...
Zhuo Huan: "A genius is always lonely."
Fu Cheng raised his head and looked at him.
Zhuo Huan asked him back: "Aren't you lonely?"
For a moment, Fu Cheng didn't know whether he should answer or not.
Zhuo Huan didn't say anything more, he took his things back to the second floor, everyone immediately stopped discussing and looked at him.
Old Joseph: "Reid?"
Zhuo Huan: "The accident of British Airways Flight 38 in 2008 was due to improper design of the fuel pipeline of the engine, and the ice slag blocked the fuel pipeline, causing the engine to stall. Unfortunately, this must not have been the cause of our accident. I disassembled a Boeing 777 five years ago, so I can assure you with absolute certainty... that the fuel lines of Rolls Royce engines will never be the same again The problem."
Everyone: "..."
For a while, I didn't know whether to feel sorry first, or to applaud you, a local tyrant who dismantled planes first.
Zhuo Huan: "It took me a month to disassemble all the Rolls-Royce engines, and I discovered a problem. Things that disappear after a crash can be water, but it can also be an obvious thing. Something that we have been ignoring.”
Fu Cheng: "What?"
Zhuohuan: "Electricity."
Old Joseph was surprised: "The telex system? Reid, this is the direction you gave up from the beginning."
"Did I mention it was a telex system?"
"what is that?"
"it."
Zhuo Huan put the things he just unloaded from the engine on the table.
Old Joseph stared at it for a while, then said in astonishment, "MCD Magnetic Chip Detector?!"
The author has something to say:
Joseph Sr.: This Boeing 767 is not bad.
RIP: I did.
Joseph Sr.: This Airbus A320 is not bad.
RIP: I did.
Joseph Sr.: This Embraer EJ190 is not bad.
RIP: I did.
Old Joseph: ...! ! ! Enough, you go! ! !
***
Fucheng: This aircraft carrier-based aircraft is good, I like driving it ^_^
RIP: I tear down…
RIP: I haven't dismantled =A=

Is there any jargon in this chapter
It seems that there is no ~
Just the last magnetic chip detector? Oh, no need to know, literally, a magnetic chip detector [?]
right! And an engine rattle! I edited OVO~
Ah yes, let me explain again, the fly-by-wire system is a computer-controlled aircraft. It’s hard to explain, you just think like this, your WINDOWS system is wrong, you can just understand it~ It’s really not good, understand it as an AI, just like a science fiction movie, it helps you drive the spaceship, and then it has a BUG.
