Rogge 318 Interim Investigation Headquarters, Seattle.

In the empty and spacious factory, a silver-white Maifei F485 is parked in the center of the factory. Dozens of researchers wearing laboratory suits kept walking up and down to debug the basic data of the aircraft. After all the variable elements were ready, Lovins, who was standing in the second floor laboratory, made an OK gesture to the people below through the floor-to-ceiling windows.

The old Joseph standing on the first floor also gave him a gesture, and then his voice was flat: "Start the experiment."

With a buzzing sound, the plane started, and the first experiment of the McFei F485 automatic cruise system officially began.

In the first three days of the actual machine experiment, the survey headquarters did not actually conduct a flight experiment, but conducted a "semi-" actual machine experiment. They simulated the relevant data on the day of the crash of the Rogge 318 on the data to observe the response countermeasures of the aircraft's autopilot system.

At the weekly meeting, Lovins published the results of this "semi-" real machine experiment: "According to the specific meteorological data given by the Russian Meteorological Administration, we conducted a total of 21 experiments in the laboratory. Aircraft experiment. The results of the experiment showed that the autopilot system of McFei F485 reacted to small ocean front waves 30 nautical miles away on 19 occasions. On 17 occasions, the aircraft chose to yaw for a certain distance when the route allowed. ."

Old Joseph continued his words and said: "This is an extremely intelligent aircraft. We all know that it will even automatically contact the tower and send a yaw permission code."

Deputy Director Andrew looked at an NTSB investigator beside him. The latter nodded and said to him: "This kind of yaw code is because the yaw distance is too short. According to the latest FAA air traffic control agreement, there is no need to obtain manual permission from the air traffic control. The computer directly approves the yaw permission. "

Lowens concluded: "So, based on the pure experimental results, the Roger 318 had an active right yaw operation due to the distant frontal wave. So far, everything is a reasonable operation of the computer."

Zhuo Huan pondered for a moment: "When will the real machine experiment be carried out?"

Old Joseph: "Four days later. According to the United States Ocean and Meteorological Administration, a frontal wave occurred in the northeastern Pacific Basin at 2 o'clock in the afternoon in the northeast Pacific Basin. Approaching. At that time, we will drive the McFly F485 for a fully simulated flight test experiment."

Four days later, San Francisco International Airport.

A brand-new Maifei F485 steadily stopped at the start of the runway, and the sun shone on it like a sharp sword. The warm daylight in the winter afternoon shines into the cockpit through the dark windshield.

Fucheng sat in the driver's seat, beside him, in the co-pilot seat, for the first time there was a person.

It was an American pilot with brown hair.

This flight test is too important to allow a slight mistake, because the ocean climate is unpredictable. No one can guarantee that a similar frontal wave will appear again. When the US Meteorological Administration detected this frontal wave, which was extremely similar to the Roger 318, everyone felt that this might be destiny, and it was destined to heaven.

A similar location, near the North Pacific Ocean.

Similar climate, small ocean front waves formed by the collision of two air masses.

But when Van Rogge found a month late in 318, they couldn't find such a perfect opportunity.

Perhaps in the midst of it, the 298 souls who had been silent on the bottom of the sea for five years also shouted.

All over the world, countless people, working together, they are walking towards that truth.

So there is no room for error.

Fucheng: "Prepare for inspection before taking off."

The deputy captain nodded and opened the aircraft safety manual: "Start the pre-takeoff inspection. The navigation lights have been turned on, confirm that the inertial navigation is turned on..."

After five minutes of dull and repeated safety inspections, the voices of Fucheng and the deputy captain rang in the quiet cockpit.

The deputy captain's name is Cade Voss. He is a very good U.S. Air Force pilot and an experienced test pilot.

Fucheng and CapitaLand have already had an extremely deep understanding of the Maifei F485, but they have not slackened. They carefully check every step, even if these steps are like an adult playing with a child's toy to them, they do not despise it.

After the examination, the two looked at each other.

Fucheng Town spoke in an orderly manner: "Confirm to take off."

The plane began to accelerate on the runway.

Its speed is getting faster and faster, and finally with a buzzing sound, it leaves the ground smoothly and heads for the sky. After making a 180° turn in the air, it turned to the west and headed toward the Pacific Ocean Basin.

At the same time, hundreds of investigators and experimenters did not waste their time in the airport laboratory.

Lowens: "Monitor all flight data in real time."

Old Joseph: "Focus on the relevant data of the aircraft's automatic cruise system."

Zhuo Huan stood in front of the command platform. He looked up at the small green dot on the radar map. Five minutes later, he calmly pressed the communication button.

In the cockpit, the man's cold and steady voice sounded.

"Cruising altitude."

Fucheng squeezed the rudder in his hand, and he glanced at the dashboard: "29,000 feet."

Zhuo Huan: "Turn on the automatic cruise system completely."

Fucheng: "The automatic cruise system has been turned on."

Zhuo Huan: "You are already close to that frontal wave."

Fucheng: "Yes."

Zhuo Huan: "There are still 35 nautical miles."

The voice fell, it was a long silence.

In the cockpit of the McFly F485, both pilots held their breaths. They looked at the weather map detected on the aircraft's weather dashboard. It's getting closer, getting closer.

There are 34 nautical miles.

33 nautical miles.

32 nautical miles...

It should be 30 nautical miles, but did not wait for 30 nautical miles. When the plane was 31 nautical miles away from the frontal wave, Fushiki's eyes dazzled and quickly turned on the communicator: "The aircraft's autopilot system has begun to turn automatically."

The next moment, Zhuo Huan calmly said: "Wait for three minutes."

Fucheng and Cade: "Yes."

Three minutes was the time when the two deputy captains on the Roger 318 ignored the aircraft and turned to the right automatically. Because of the abdominal pain, the deputy captain David couldn't even bother to look at the dashboard; because of the sudden abdominal pain of his companion, the other deputy captain William failed to notice that the plane was turning right away. It took 2 minutes and 57 seconds since they finally discovered that the plane was turning and decided to make a maneuver.

Time passed, and when the plane had quietly turned to the right by a big 35° turn, Cade turned his head and looked at Fucheng: "Found steering."

Fucheng immediately stretched out his hand: "Turn off the aircraft's automatic cruise system."

"Pattern—"

With a crisp sound, both Fucheng and Cade stared at the aircraft dashboard.

This second became extremely long in their eyes.

Fucheng seemed to hear his heart thumping in his chest, beating slowly. He didn't know what he wanted to see, so he turned off the automatic cruise system easily? Then this experiment is over, he and Cade are in no danger, and they can easily take over the plane.

However, the automatic cruise system cannot be turned off. This is the situation that Qi Zhifeng, David and William actually encountered on the Roger 318.

They should choose to turn off the automatic cruise system at the first time.

This is common sense, a common sense that is basic to the extreme. Any pilot, even if he has not graduated from a flight academy, should know the most basic common sense.

Can the automatic cruise system be simply turned off? Or is there something really wrong with it?

One second later, Zhuo Huan watched the data transmitted by the plane, and at the same time, Fucheng's calm voice came from the communication audio: "Confirm to turn off the automatic cruise system and start manual driving."

After closing his eyes, Zhuo Huan sighed softly.

On March 16, 2022, the flight test experiment ended.

Zhuo Huan scanned hundreds of investigators in the conference room and said: "Experiments have proved that on the day of the crash, it was confirmed that the Rogge 318 had encountered ocean frontal waves and the aircraft's autopilot system directly chose to yaw to the right."

Deputy Director Andrew nodded slightly and said: "This should be the direct cause of the crash."

Lowens: "During the test flight, the pilot easily turned off the automatic cruise system, so we ruled out the design of the aircraft. Then there are only two possibilities. The first is the pilot's control error. They have a chance to save the aircraft. Before the aircraft completely loses control, they have about 30 seconds to save it, and it only takes 1 second to turn off the autopilot system. The second possibility is that the aircraft parts are malfunctioning."

Zhuo Huan looked at Lawrence: "Have you found the other two black boxes?"

Lawrence: "A black box has been picked up, and now it is sent to McFly's headquarters in Los Angeles to analyze the data."

Zhuo Huan: "When can I get the plane up?"

Lawrence's face changed slightly, he was silent, and said helplessly: "Give me another month and a half."

Zhuo Huan looked at him steadily.

Lawrence pursed his lips and sighed: "Reid, this is not working overtime and staying up late. It is not something that can be solved by spending money. I have arranged for someone to order a giant water tank that can hold an airplane. If you want a broken airplane , I can catch it in seven days. But if you want a complete Roger 318... give me a month and a half."

Zhuo Huan glanced at him deeply and nodded.

Lawrence breathed a sigh of relief.

Zhuo Huan looked at Old Joseph: "Where is Su Fei?"

Old Joseph smiled: "Of course he followed to Los Angeles. By the way, let me tell you something before Fly leaves."

"Um?"

"Reid, for seven days, he will definitely bring back the black box and the data in it intact for you."

Los Angeles International Airport.

NTSB investigators carried a heavy box and walked in front. The punk boy followed them and went to the underground parking lot together.

The staff of McFly Labs has been waiting there for a long time.

Su Fei, the person who came to pick them up, actually knew him. He raised his eyebrows when he saw Johnny Berkeley, the director of the public relations department of Mai Fei.

When Johnny saw them, he immediately came over with a smile on his face: "Please come with me, the Mai Fei laboratory is ready, just waiting for you to go." Then, he looked down at Su Fei and said with a smile: " Long time no see, Mr. Su."

"It didn't take long, more than half a year?" Su Fei thought for a while: "Last time we came, it seemed that you were not the one who came to pick you up."

Johnny smiled slightly: "Last time I was on a business trip in Europe, this time I was in Los Angeles, so I came here."

Su Fei thought for a moment, but also felt that there was no problem. He looked at the box held by the NTSB investigator, thought of the black box inside, and thought of the test flight experiment that Fucheng went to San Francisco two days ago.

The punk boy muttered, "Do you really want to find out the truth?"

It's like destiny.

The time and place are favorable, and the flight test experiment was carried out successfully, and very satisfactory results were also obtained.

It's like destiny again.

Lawrence's salvage company found one of the two remaining black boxes in the deep-sea silt 15 nautical miles from the wreckage of the plane.And the integrity of this black box was actually better than the first black box found.When Su Fei saw it, he knew that at most seven days, he would be able to parse out the data in this black box, even in less than seven days.

Moreover, this is installed in the rear of the aircraft, the main black box that records almost all the control data of the aircraft.
