The electronic flight recorder, 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 during the flight.

After listening to the last 30 seconds of the cockpit audio of the JAL JL917, Zhuo Huan immediately returned his focus to the FDR. He wanted to check the flight data before the crash.

Su Fei adjusted the flight data.

Zhuo Huan: "Look at the last 30 seconds first."

Su Fei: "Okay, come on."

The moment the Enter key was pressed, the dense data curve immediately covered the entire computer screen. In the eyes of laymen, this graph is intricate and complicated, with all kinds of data squeezed together, making it impossible to start.

Zhuo Huan looked extremely fast.

He almost glanced at ten lines, kept pulling down the progress bar, from the countdown of thirty seconds to the countdown of sixteen seconds in the blink of an eye.

When he saw sixteen seconds before the crash, his eyes stopped.

Zhuo Huan: "Enlarge this section and project it on the screen, and only capture these two seconds."

Su Fei ordered to project 16 to 14 seconds of data on the screen in a few clicks.

Zhuo Huan: "The audio of the same time period is also put up to intercept the cockpit conversation."

"Okay!"

One person speaks quickly, and one person does it quickly.

The staff of other investigative agencies present were still at a loss. Su Fei had already followed Zhuo Huan's instructions to project 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 was wearing skull earrings, and the ends of his hair were still dyed a little green that didn't fade away completely.

Has a strange aesthetic and punk appearance.

But above these-he is a genius.

Zhuo Huan asked Su Fei to overlap the flight data and audio, and he pressed the play button.

"Preparing to put down the landing gear... Wait, I suddenly lost thrust. 』

From the 16th second to the last 14 seconds before the crash.

The deputy captain Maeda Shosuke exclaimed in surprise. He was surprised to find that he had lost the thrust of the engine.

His reaction was extremely fast. Flight data showed that in the 16th second before the crash, the four engines suddenly turned off 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 speaker.

His behavior made everyone in the audience incomprehensible, but they all followed this man and listened over and over again.

At the end of the seventh time, he suddenly opened his eyes: "Play the last thirty seconds of audio again from beginning to end."

Su Fei: "...OK."

"Confirm that the throttle is tightened. 』

"It has been confirmed that the throttle is tightened. 』

"The flaps are opened 30 degrees. 』

...

"Ah, get up, pull up! 』

"GLIDE SLOPE! GLIDE SLOPE! GLIDE SLOPE! 』

"Ahhhhhh, I'm going to hit it! 』

"boom"

After the terrible and harsh impact, there was the sound of zila zila electric current. Soon, the black box stopped working, and it recorded the mission it needed to undertake.

Zhuo Huan: "Listen again."

Su Fei: "Okay!"

Listening over and over again, at the same time, Su Fei continued to process the relevant data of the black box.

Now what they heard and saw was only the last 30 seconds. This black box completely recorded all the data of the 30 minutes before the crash.

Zhuo Huan: "Have you processed the last ten minutes of data?"

Su Fei: "Huh? Not yet, it has only been processed for five minutes."

"Listen for five minutes first."

Su Fei: "..."

This horse riding is definitely a squeeze of child labor, absolutely!

He scolded the devil 10,000 times in his heart, and the punk boy slumped his mouth, and projected the five-minute data he had just processed on the big screen for everyone to observe and analyze.

Aircraft accident investigation is destined to be boring, and it is impossible to get results quickly.

Investigators from other agencies went to work on their own affairs. Only the UAAG people were still here, listening to the voice in the black box with Zhuo Huan over and over again.

"It's not right."

Fucheng raised his head quickly and looked at Zhuo Huan.

Lifting his right hand to cover his lips, Zhuo Huan looked down at the ground, his long and narrow eyebrows locked tightly.

Old Joseph: "Reid, what's wrong. Judging from the flight data curve, there is nothing wrong, except that the four engines suddenly turned off when the countdown was 16 seconds. Before that, the aircraft data was all normal."

Zhuo Huan did not answer. He closed his eyes, and then the audio started a new round of replay. He listened carefully, and suddenly opened his eyes.

"The sound is too muffled."

"Huh?" Everyone looked at each other, they all saw the confusion in each other's eyes.

Fucheng is also at a loss.

Too boring?

What sound is too muffled?

A conversation between the three pilots in the cockpit?

Zhuo Huan slowly raised his head. Old Joseph was sitting in front of him, so he looked at him at the first glance. But after a moment, he turned his gaze away and looked at the dark-haired young man standing beside him.

After the two looked at each other, Zhuo Huan said, "You used to be a carrier-based pilot."

Fucheng narrowed his eyes, and for a long time, he nodded: "Yes."

As soon as the words fell, there was an uproar in the audience, and Old Joseph blew a whistle.

Su Fei jumped up directly from the chair: "Fuck, brother, the carrier pilot? Are you so awesome?! Fuck the carrier!"

Fucheng glanced at him.

It is to fly the aircraft on the aircraft carrier, not the aircraft carrier.

But didn't bother to correct him.

Zhuo Huan sat on the swivel chair, tapping gently on the arm of the chair with his right hand.

"Civil passenger aircraft and military aircraft, because of the difference in engine performance, cause different engine vibrations when fueled. But this difference is difficult for human ears to distinguish. But carrier-based aircraft are different." Zhuo Huan said. Looking at Fucheng with a sharp gaze, "The carrier-based aircraft is extremely difficult to land, so the difference in engine noise at this time can be intuitively observed by human ears."

Fucheng's expression was calm: "Yes, the engine sound of a carrier-based aircraft when it is landing is very different from other aircraft."

Zhuo Huan: "JL917's engine rang, which is different from the normal McFly F435."

Old Joseph flashed in his mind and said to Su Fei: "Quickly, find a normal F435 engine soundtrack and listen to it."

Su Fei: "..."

You all squeezed me as a child laborer!

Su Fei quickly found a section of F435's normal engine soundtrack from the data network and released it.

But after listening.

Old Joseph: "...is it different?"

Fucheng smiled and said, "I don't think so."

Su Fei raised his hand: "I don't think so!"

After listening to them, Zhuo Huan let out a chuckle 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 overlapped the engine soundtrack of the normal F435 aircraft with the soundtrack of the JAL F435.

At the moment when the two audio tracks overlap, Fucheng's lips moved, and it was hard to conceal his surprise.

After a long silence.

Su Fei: "...You can hear this when you step on a horse, but it's not a human being."

The punk boy did not deliberately lower his voice, and these words also steadily passed into Zhuo Huan's ears.

He rarely pretended to be forced, but told the truth and explained: "Because this is a Mai Fei plane."

Old Joseph: "I know that you used to be the chief designer of McFly Corp., but haven't you not participated in the design and improvement of F435."

Zhuo Huan's eyebrows moved: "Lina told you?"

Old Joseph: "Yes, have you participated in the design of F435?"

"No."

As soon as everyone breathed a sigh of relief, the Great Demon King said lightly in a plain tone: "But I dismantled an F435."

"..."

Finland, Helsinki, Aviation Safety Agency.

Early in the morning, media reporters blocked the door of the Aviation Safety Bureau.

The Ministry of Information and Foreign Affairs of Finland prepared the conference room. At 9:50 in the morning, media reporters entered the conference room and waited for the press conference to begin.

At ten o'clock, the door of the meeting room opened. A slim and slim blonde girl in a red dress walked into the conference room. Her slender high heels made her legs straight and slender. With a generous and beautiful smile, she stood in front of the rostrum and said gently.

"Hello everyone, I am Stephanie·Comte, affiliated to the multinational aircraft accident investigation organization UAAG. Today, I am responsible for reporting to the public that UAAG's investigation progress on JAL JL917 crash..."

After half an hour's mission report, the media reporters asked questions.

These seemingly dignified reporters in suits turned into sharp-edged, sharp warriors at this moment, attacking the French girls on the podium. It's a pity that everything was defeated by her elegant and perfect smile, and Lina was able to answer every question from the reporters 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 tell my father."

When getting in the car, the blonde saw a decadent Asian man sitting on the stone at the door of the Aviation Safety Bureau. He looked at the ground in despair, his suit was wrinkled and dirty, not knowing how many days he had not been changed.

Lina watched for a while, and the Finnish officials followed her gaze.

"Oh, that's an air crash survivor. He came to us every day in the past few months and asked us to severely punish the deputy captain, saying that the deputy captain kidnapped the plane and caused the crash. But the deputy captain is dead, and we too If you don’t understand his needs, you can’t drive him away. Now that the truth is clear, he should feel better, it’s not a human factor.” The official turned his head to look at Lina and said with a smile, “I hope Mr. Patrick can find out the truth sooner. ."

Lina: "I will tell Reid."

Find out the truth?

It's easier said than done.

They just gave up a wrong path and seemed to have found a new direction.

However, looking up from a distance, the road ahead is covered by thorns, dark fog and thick clouds, and there is no end in sight.

To find out the truth quickly, this probably requires a miracle.

But isn't Reid itself synonymous with miracles?

The French girl smiled slightly and got in the car and left.

Investigation headquarters.

After the new investigation direction came out, everyone fell into a new problem.

Old Joseph: "The engine quake is indeed different, but from the flight data, this anomaly has not affected the normal operation of the engine. It can be speculated that the quake is related to the cause of the accident, but what is the specific cause and where should we start? "

"Will it be related to the low-pressure turbine module?"

Old Joseph: "The low-pressure turbines of the four engines went wrong together?"

"Maybe it's a fan module?"

Old Joseph shook his head: "I guess, maybe when the gas flows out of the tail nozzle, there is an abnormal sound... Hey, right, what about the Reid people?"

Going down the stairs to the first floor, Fucheng searched for a long time among the messy 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 was a little stain on the white T-shirt, and even on the thin arms.

After removing the things, Zhuo Huan lowered his head and saw Fucheng.

Raised his brows, Zhuo Huan: "How long have you been watching?"

Fucheng: "Old Joseph and the others are discussing it, Teacher Zhuo, why don't you go."

"you?"

Fucheng: "..."

Fucheng: "Why don't you go?"

Zhuo Huan smiled.

He jumped and jumped off the ladder.

Zhuo Huan: "I listened to them for half an hour."

Fucheng: "Huh?"

Zhuo Huan: "I have gained something and got some inspiration."

Fucheng: "For example?"

Zhuo Huan looked at him: "A thing that quietly disappeared after the crash has the power to damage four engines at the same time. This is what they concluded."

Fucheng: "..."

He especially wanted to say that Joseph Sr. did not summarize these well-known things, and they also put forward many directions for investigation. Such as low-pressure turbines, fan modules, tail nozzles...

Zhuo Huan: "Geniuses are always lonely."

Fucheng raised his head and looked at him.

Zhuo Huan asked him back: "Aren't you alone?"

Fucheng didn't know for a while whether he should answer or not.

Zhuo Huan didn't say any more, he took the things back to the second floor, everyone immediately stopped discussing and looked at him.

Old Joseph: "Reid?"

Zhuo Huan: "In 2008, the British Airways Flight 38 accident was caused by improper design of the engine's oil pipeline. Ice slag blocked the oil pipeline and caused the engine to stall. This is very similar to our accident. As we all know, they carried out the oil pipeline 10 years ago. Improved. Unfortunately, this must not be the cause of our accident. Five years ago, I dismantled a Boeing 777, so I can assure you with certainty...The oil pipeline of Rolls-Royce engines will never appear again. Similar problems."

Everyone: "..."

For a while, don't know whether to regret first, or to applaud you, the local tyrant who dismantled the plane.

Zhuo Huan: "It took a month to tear down all the Rolls-Royce engines and I found a problem. The thing that disappears after the crash can be water, but it can also be an obvious thing. Things have been ignored by us."

Fucheng: "What?"

Zhuo Huan: "Electricity."

Old Joseph was surprised: "Telex system? Reid, this is the direction you gave up from the beginning."

"Did I say 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 fixedly looked at it for a while, and said in astonishment: "MCD magnetic chip detector?!"

The author has something to say:

Old Joseph: This Boeing 767 is good.

RIP: I did.

Old Joseph: This Airbus A320 is good.

RIP: I did.

Old Joseph: This Embraer EJ190 is good.

RIP: I did.

Old Joseph:...! ! ! Enough, you go! ! !

Fucheng: This carrier-based aircraft is not bad. I drove it and I liked it^_^

RIP: I will open...

RIP: I haven't demolished =A=

Are there any technical terms in this chapter?

It seems that there is no~

Just the last magnetic chip detector? Oh, there is no need to know, it is literally, the detector of magnetic debris [? 】

right! There is also an engine noise! OVO I made up~

Ah yes, let me explain again, the telex system is a computer controlled aircraft.It's not easy to explain, you just think so, your WINDOWS system is wrong, almost understand it~ It really can't, understand it as an AI, just like a science fiction movie, it helps you drive the spaceship, and then it has a bug.
