Return to 2000: Captain of the Great Powers

"Is there really someone in this world who can record 250 correspondences by memory? No, not to mention that there is no data to support it now. It's like the engine speed change can only be judged by sound. In the difference between the angle of the opposite stick Without any auxiliary support, is this really possible?" In the cockpit of Southwest Flight 3102, the captain was still expressing great doubts about Xu Cang's proposal.

Leaving aside the issue of the throttle, let’s just take the operation of the sidestick on the pitch as an example.

The actual pitch of the aircraft can be obtained from the backup attitude indicator, but the amount of sidestick operation is difficult to quantify.

The so-called scale itself does not exist, just like the throttle has a total of [-] scales except reverse push, but there is no scale similar to a scale on the throttle console itself, and there is no one degree, two degrees, or ten degrees. The term "throttle" is just to simplify and define the corresponding relationship between the position of the throttle stick and the thrust value, but how to divide the position of the throttle stick depends entirely on the pilot's self-perception.

That's right, if it can be successful according to Xu Cang's statement, then the pilot must first use his own perception to divide the position of the throttle lever.

The same thing happens with the delineation of the sidestick positions.

There is also no such thing as how many degrees the sidestick is pushed forward and how many degrees it is brought back. Everything is divided based on the pilot's own feeling.

In fact, in the opinion of the captain, this method has completely exceeded the physiological limit of the human body.

Not only must the memory be extremely amazing, but also the physical perception ability is extremely delicate. At the same time, the ability to allocate attention must also be excellent, otherwise it will not be able to be used flexibly in flight. Finally, certain flight knowledge and skills are also required.

These requirements are indispensable.

If there is anyone in this world who can do it, then it can only be Xu Cang, but Xu Cang is already in trouble, and whether he can survive until Japan lands is another matter.

In other words, Xu Cang wants to complete this impossible task with his current body that is almost reaching the critical point?

Richard Bayer didn't quite believe it either. He persuaded Xu Cang softly: "I also think it's...difficult. If you are healthy, I may have no objection, but now you...Xu Cang, what do you say?" The method...no one can do it, maybe, we should think about other methods."

Xu Cang shook his head: "There is no other way, at least I can't think of it, and this method is not impossible. Richard, you should give up your seat first, someone wants to take your seat."

"Someone wants to take a seat, who?" Richard Bayer was taken aback: "The person you are talking about? But..."

Xu Cang didn't answer Richard Baier's words, but raised his volume slightly: "Shuyue, come in!"

About ten seconds later, Xia Shuyue came to the cockpit nervously, looked at Xu Cang first, saw Xu Cang's lips slightly purple, and said eagerly: "Xu Cang, you..."

Xu Cang waved his hand: "Shuyue, I can hold on for a while, don't worry. Now we are returning to Japan, and you may need to complete the landing."

"I?"

"she!"

These two exclamations were almost made together, from Xia Shuyue and the captain respectively.

After the initial shock, Xia Shuyue didn't express any more. Instead, the captain chattered and expressed his objection: "She is flying, is the model 320? What level, which company, CAAC? Does CAAC have females?" Pilots, I don’t remember, even our FAA has only a very small number of female pilots.”

The captain's series of questions were like a series of cannonballs. After all, it was related to his own life, so he couldn't be careless.

Xia Shuyue was a little embarrassed, each of the three people in the cockpit was much smarter than her.Therefore, facing the captain's questioning, she didn't have too much of a violent reaction, but was slightly puzzled why Xu Cang asked herself to complete the landing.

Xu Cang was exhausted physically and mentally at this time, so he didn't waste any effort to persuade the captain, he just waved his hand: "You go out first, Richard, you sit in the observer's seat, Shuyue, you come to the left seat."

The captain was so anxious that he was about to sweat. Could it be that Xu Cang lost too much blood and lost his mind?Looking at Xia Shuyue's expression, she was obviously stunned and panicked, which in itself already explained many things.

Not to mention the captain, Xia Shuyue herself was not confident: "Xu Cang, I have never driven a 320 before."

Hearing this, Richard Baier and the captain froze on the spot as if time had frozen, and then even Richard Baier spoke: "Xu Cang, this matter..."

"Richard, I don't have the strength to argue with you, trust me."

Richard Bayer was silent for a full ten seconds, and finally untied his seat belt without saying a word, and opened the seat to make room for Xia Shuyue.

Seeing this, the captain lost his mind and exited the cockpit cursing, while Richard Bayer was sitting in the observer's seat. He wanted to see what Xu Cang was doing.

Although Xia Shuyue didn't have much confidence, she still sat on the left seat according to Xu Cang's suggestion.

As soon as he sat down, Xu Cang apologized softly: "I'm afraid you won't be able to use the parachute."

Before, Xu Cang had thought that if there was nothing he could do, he would let Xia Shuyue parachute to survive.At that time, he did not think of the impact of the solar storm on the electronic controller of the automatic parachute opening.

Skydiving is an extremely professional activity. If ordinary people do not have the aid of equipment, it is basically the same as sending to death.

Xia Shuyue was not disappointed at all. To be honest, letting her leave Xu Cang to escape alone was an extremely unacceptable thing. Now that this possibility has eliminated this possibility, it is a good thing.

This sentence alone contains a lot of information.Richard Bayer's eyelids twitched a few times. It seemed that Xu Cang had other arrangements for Xia Shuyue, and this arrangement was based on his extreme pessimism about the landing of the plane.

Xia Shuyue fastened her seat belt, this one does not need Xu Cang's help: "What do you want me to do?"

"Shuyue, I took you to Yanshan Aviation School to experience flying before, do you remember?"

Xia Shuyue nodded: "Well, I remember."

"At that time, you copied a complete takeoff and landing by memorizing my thrust settings and attitude values ​​in all stages." Xu Cang said softly: "What you have to do this time is essentially similar to that time, but the difficulty is higher. Much, much taller."

While speaking, Xu Cang organized his language a little bit, and explained to Xia Shuyue carefully the plane's failure, the current situation and his disposal plan, especially when it came to what Xia Shuyue needed to do. When doing things, he spoke very carefully.

Anyway, Xia Shuyue is still a novice in flying, she must know exactly what she is going to do.

"You have to rely on your own feeling to divide the interval scale of the throttle stick and the side stick, at least 250 scales. In addition, you have to find and memorize the attitude and thrust value corresponding to each scale." Xu Cang said quietly: "I still have some energy. Later, I will take you to experience the correspondence of all positions of the throttle stick and side stick many times. You must complete the tasks I entrusted to you during this period. This is the only thing I can do now. Do it, I can’t last too long, the approach and landing can only be done by you, I will remind the required thrust value and attitude value from the side, you just need to set it according to my requirements.”

In short, Xu Cang wanted Xia Shuyue to memorize the corresponding relationship between all postures and thrusts, and then complete the landing with his own hands instead of his own under his guidance.

It doesn't matter how perfect the landing is, as long as it can fall.

All the difficulty in this matter lies in finding and memorizing the corresponding relationship of the data, which is actually less difficult in practice.

Xu Cang waited for a while, and when Xia Shuyue seemed to have digested everything, he asked in a low voice, "Understood?"

Xia Shuyue's bright eyes flickered with soft light: "Understood."

"Can it be done?"

Xia Shuyue lowered her head and pondered for a while: "I will try my best."

"Okay, this is enough." Xu Cang pointed to the oxygen mask that Xia Shuyue had put away: "Put on the oxygen mask."

Since the beginning of the large-scale power outage, the aircraft has been in the state of slow decompression, but before the problem, the aircraft was basically in the state of climbing altitude, and most of the outflow valves were closed. It is better to ensure the sealing of the engine room, and the rate of slow pressure release is not fast.

Previously, the altitude of the cockpit of the aircraft was rising at a very slow speed, which gave the people in the cabin time to adapt to the body, so the physical sensation was not strong.

The oxygen system in the cockpit lasts much longer than the oxygen generator in the passenger cabin, but it is limited after all, and once Xu Cang puts on the oxygen mask, he will not take it off. He will use [-]% pure oxygen to keep himself in shape as much as possible.

Therefore, Xu Cang never used the oxygen mask.

However, it is different now.For some time to come, Xu Cang must cheer up, not only Xia Shuyue, Xu Cang will also face a huge workload.

In order for Xia Shuyue to experience the attitude and thrust changes of the complete journey, the aircraft will continue to experience unpredictable state changes in the following time.

Although the current altitude is sufficient and there is a lot of room for recovery, it also requires Xu Cang to devote a lot of energy all the time, using the only remaining, fairly normal rudder to prevent the aircraft from entering some complicated states that cannot be recovered.

The static stability of a large airliner can automatically correct most of the deviation states when the altitude is sufficient, but some cannot be corrected, such as the Dutch roll.Therefore, Xu Cang still has to raise his spirits.

In addition, according to the display of the cockpit altimeter, the altitude of the aircraft cockpit has also approached [-] feet, which is high enough, and it is time to put on an oxygen mask.

Xu Cang could still move his right hand, so he showed Xia Shuyue how to wear an oxygen mask. It was not difficult, and Xia Shuyue quickly learned it.

Just as Xu Cang put on the oxygen mask, he felt a gust of cool air rushing into his nose and mouth, which was refreshing.

Xu Cang did not choose the emergency position with the highest flow rate, but a slightly lower level of [-]% pure oxygen, which is enough for Xu Cang.

Airbus's oxygen mask is not a face covering, it just covers the mouth and nose.However, this is also good, that kind of full-face mask is easy to feel depressed and uncomfortable after wearing it for a long time.

Perhaps because of the effect of breathing pure oxygen, Xu Cang's spirit improved slightly. He glanced at Xia Shuyue and confirmed that Xia Shuyue had put on the oxygen mask correctly. If you can’t move, you can move the throttle lever.”

Airbus's aircraft is later than Boeing's and has a much higher degree of automation. After putting on an oxygen mask, it may automatically switch to the microphone on the mask.

After being amplified by the microphone of the oxygen mask, Xu Cang's voice seemed muffled.

Xia Shuyue put her right hand on the accelerator: "What should I do?"

"If you need to rely on the sound to judge the magnitude of the thrust value, you need to determine the idle and maximum thrust values ​​first, and then you can have an idea of ​​the relative magnitude of the engine sound." Xu Cang said: "One at a time, directly add Go to the front, then slowly recover, until it reaches the idle position, and the other throttle stick does not move."

If you want to distinguish the size of the engine, you need to have a concept of comparison, then you should determine a maximum and minimum value.Because I don't know where these two values ​​are now, I have to let the throttle stick go a full distance, so that Xia Shuyue has a relative concept.

In fact, there is another value that Xu Cang did not mention, and that is the median value.

For cruising descents, the thrust of the middle value is actually relatively appropriate.Determine the beginning and end, and then set the middle value, the thrust of this middle value will be used in the descent in the future.

Richard Bayer was stunned for a while when he heard it behind him. He probably understood what Xu Cang meant, but he didn't expect that there were so many specific details in it, including determining the maximum and minimum values.

"If I move, the attitude of the plane will deviate, right?" Xia Shuyue worried.

Xu Cang slightly moved the rudder pedal: "It's okay, you will only move one throttle lever, and in the end it will only cause a drift with inconsistent thrust. I can use the rudder to correct it."

"However, the thrust value changes non-linearly, and the resulting yaw deviation of the nose will be unpredictable, and it may be extremely violent. If the correction does not keep up." Richard Beyer is not without worry. .

"With me here, nothing will happen." Xu Cang confirmed, then looked at Xia Shuyue: "Let's get started."

Over Canada, the cabin of ANA flight NH106 was filled with an atmosphere of extreme anxiety. According to the time, the plane should have landed at Los Angeles International Airport by this time, but they have been circling after entering Canadian airspace, not even approaching the US border.

After a long time, anyone who pays a little attention can feel that there is something wrong with the plane.

That's right, this ANA flight 106 was trapped because there was no airport for landing. At this time, the remaining fuel of the plane was already lower than the emergency fuel level, and just 10 minutes ago, the crew had announced MAYDAY. But neither Vancouver Airport nor Halifax Airport can make room for landing.

At this time, the crew members in the cockpit were already discussing the feasibility of a possible forced landing.

Perhaps it was the dignified atmosphere in the cockpit that spread out, making all the young and beautiful flight attendants frown.

In the first-class cabin of that 747, there were only a few people, and a young man in his early 20s was lying on the single sofa in the front row, with an open magazine spread out on his body, breathing evenly, looking Is asleep.

After appeasing the passengers in the economy class, the purser returned to the work room in the front cabin. When passing by the front row, his wrist was suddenly grabbed.

In astonishment, he lowered his head and saw that it was the young man resting with his eyes closed.

The purser was about to say, "Sir."

"How much oil is left?" The young man slowly opened his eyes, only to see his sword eyebrows and starry eyes, like an unsheathed sword, full of indomitable sharpness.

The purser was taken aback: "Sir, what did you say?"

The young man let go of the chief purser's wrist: "This flight is estimated to last eleven hours. Usually, this kind of route can only carry fourteen hours of fuel at most. Now, it is exactly fourteen hours. It stands to reason that the current fuel It’s almost bottoming out.”

The young man frowned, and his eyes were very different: "But we are still circling now, approaching from a certain height, and we need to consider the possible go-around fuel. At least four or ten minutes should be left, but I don't think you have any left." Four 10 minutes of oil."

"So, what the hell are you doing?" The young man's voice became colder: "The plane has entered emergency fuel?"

The purser's eyelids twitched, he didn't expect the young man to be so good at flying, but he still wanted to prevaricate: "Sir, our plane is normal."

"Everything is normal?" The young man smiled softly: "If everything is normal, then why did I just see that No. [-] in the front cabin workshop was trying to broadcast a short video about the anti-shock posture?"

"What?" The flight attendant turned pale with shock, and when he looked back, he noticed that the curtain of the front cabin work room had not been drawn. From the young man's seat, he could directly see most of the front cabin work room.

In fact, it's not to blame for No. [-]'s carelessness. She just tried to run the short video clip of the anti-shock posture on the multimedia operation interface of the front cabin workshop.This interface is not big, and she chose to mute the sound, there will be no external sound, even if it is seen by the passengers, the passengers will not know what it is, so she did not pull the curtain.

However, I didn't expect that the young man not only noticed, but even understood the content.

However, at this time, the chief purser still wanted to cover up again: "Sir, our crew has undergone strict training and will definitely ensure the safety of passengers. Please don't have any extra fantasies, just follow our instructions." .”

"Guarantee my safety?" The young man put the magazines on his body aside: "Anti-shock posture, are you going to make an emergency landing? If the dispatcher wants to plan an alternate landing on the route from Tokyo Haneda to Los Angeles, then choose There is not much range. This is a 747. In the whole of Canada, there are only Vancouver, Halifax and Gander airports available for landing. According to the usual route, Gander Airport is the farthest away. Based on what I told you Estimated remaining fuel, Gander Airport is also unable to go, so Halifax and Vancouver are left. Although both are possible, Halifax is more inclined to come from Europe as an alternate landing site Most of the alternate landing sites for Asian routes are Vancouver, so now the plane is directly below Vancouver?"

Hearing that, the purser was terrified, and asked tremblingly, "Who are you?"

The young man stood up slowly: "I will not entrust my safety to the crew who can fly enough fuel to make an emergency landing. If I were the president of ANA, I would permanently ground the pilots in the cockpit. Those few people, this kind of decision-making is simply a disaster."

"Sir, what are you doing?" The purser's heart tightened.

The young man tightened the knitted sweater on his body and smiled: "Of course my life is in my own hands. Tell the cockpit to let me complete the forced landing."

The purser was stunned on the spot: "Sir, we won't allow it."

"If the cockpit doesn't allow it, then tell them that the Great Plains don't exist around the Vancouver Airport. If they expect to make a forced landing on the Great Plains, it can only be a dead end, and there are no stretches of water around. Forced landing is also impossible." The young man said calmly, "But, I know where to make a forced landing!"

"Where?" the purser asked almost reflexively.

The young man pointed to the cockpit door: "Let me in first, is that okay? Or, you can relay my words to the cockpit, and they will let me in."

"Ah? Oh oh!" The purser smelled a trace of extraordinaryness in the young man. If it was just a message, it would not be an excessive request. Anyway, the final decision is made by the cockpit: "Sir, why don't you wait a moment?" wait!"

The purser collected his mood and walked forward.However, before he took two steps, he suddenly thought of something and looked back at the young man: "Sir, what is your name?"

"Me?" The young man showed a sunny smile: "I, my name is Xu Zhao!"
