In the cockpit of Shanhang Flight 9451, after the plane took off and entered a steady climb, the surrounding area was still pitch black. The departure time of this flight was too early and there was still some time before the sunrise.

It’s not that Shanhang has no other flights to Hanjing at relatively normal times, but the next flight will have to wait until after 3 pm before taking off. When it arrives at Hanjing Airport, it will be close to 6 pm. For these people who are anxious to go to the General Administration to file a lawsuit, things cannot be delayed at all, so they insisted on choosing such a flight that is actually anti-human at the time of departure.

About ten minutes after takeoff, the plane climbed to 7,200 meters. If it is in the western region, this altitude is far less than the cruise altitude, but in the eastern coastal areas, due to the extremely busy airspace, the plane will generally not be allowed to reach too high altitude.

After the leveling of 7,200 meters, the originally set cruise altitude is 9,200 meters. If Shi Qi was on a Boeing plane, Wu Taiming would adjust the cruise altitude to 7,200 meters. If he went up to the higher altitude in the future, he would not be able to trigger the unplanned down fault light after the predetermined cruise altitude was not reached, which involved the working logic of the supercharge system.

However, unplanned decline cannot be considered a failure, it is just a state that deviates from preset conditions. In the handling procedure, only the cruise altitude can be set to a relatively low altitude.

Unlike Boeing's boost logic, the Airbus flight crew monitoring system works without human control. The system will change the air pressure in the cockpit according to the external plan based on the signals received by the flight management and guidance system according to the external plan under the action of two cockpit pressure controllers, one residual pressure control unit, three motor-driven outflow valves, one control panel and two safety valves.

Due to Airbus' extremely high degree of automation, if FMGS data cannot be used for automatic boosting, the flight crew can complete artificial boosting control by adjusting the elevation of the landing airport. After that, the boosting system will use the manually adjusted landing airport elevation to adjust its own boosting plan.

In a sense, this has something in common with Boeing, that is, when the aircraft does not supercharge according to the normal supercharge plan before reaching the predetermined cruise altitude, the aircraft instead readjusts its supercharge logic according to the altitude of the departure airport (this is actually a relatively big hidden danger).

Although there are certain differences in the role of supercharge logic and crew, the supercharge profile is similar, namely the ground, takeoff, climb, cruise, descent and interrupt methods.

The logic of the definition of the ground method is that before takeoff and five seconds after landing, the outflow valve remains completely rested to ensure that there is no residual pressure in the cockpit. After grounding, if there is still residual pressure in the cockpit, it is released at a vertical rate of about 500 feet per minute.

Generally speaking, there should be no cockpit boost after landing, or at least there should be no overly obvious boost. Because once the pressure in the cockpit is not released, it may lead to a relatively embarrassing situation, that is, the cabin door cannot be opened.

In the takeoff method, before the aircraft is about to take off, the pressure of the aircraft head is steep, and the supercharge system will change to the cockpit for pre-pressurization, that is, the starting cockpit height of the aircraft is not the altitude of the airport, but the difference between the two is 0.1 PSI, and the starting cockpit height of the aircraft will be slightly lower...

After that, the aircraft supercharged according to the expected arrangement rules when taking into account the actual climb rate, and finally completed the cruise with a cockpit height of no more than 8,000 feet. However, unlike the climb method, when the supercharged system switched to the descent method, it actually released the cockpit pressure before landing to a pressure height of 0.1 PSI higher than the landing airport with a relatively gentle cockpit drop rate.

Generally speaking, the cabin height drop rate will not exceed 750 feet per minute, taking into account passenger comfort. Once landed, the aircraft will fully open the shutter under certain conditions to ensure complete pressure relief and reciprocating cycles.

Of course, from the perspective of the pilot, Airbus' supercharge system is obviously highly automated, which is safer and more comfortable. However, it is not that Airbus overwhelms Boeing in supercharge, but Boeing's supercharge logic, especially in classic models, actually has loopholes. In some cases, the pilot actually makes only a relatively small mistake and will lead to very serious consequences. If placed on an Airbus aircraft, this kind of infinite expansion of this error will not occur. (I don't know if there are any flying friends who fly to Boeing, at least the supercharge logic of the 737 is really not good.)

Turning the cockpit light from off to dark, Shi Qi pulled the seat back and took the pillow that the flight attendant placed on the observer's seat sideways.

For pilots, some small objects are necessary. For example, newspapers are used for sunshade. If there is no newspaper to shade the sun, the solar energy will make the unit vaguely at high altitudes during the day. However, later crews have eliminated newspapers and switched to some customized sunshades. Some aircraft models behind them even have such a system.

In addition to sunshade, there is another pillow. You don’t need to bring this thing yourself, because it is available on the plane, and the flight attendant with a little work experience will know that he will send a sufficient amount of pillows into the cockpit before taking off.

Of course, the pilot does not sleep in the cockpit, but is used as a waist. Although the surface of the cockpit seat is designed to be soft, it cannot be held for several hours. If there is no pillow to support it, most pilots will lose their waists when they are thirty-five years old.

After stuffing the pillow behind his waist, Shi Qi winked at Wu Taiming. Wu Taiming was very clever and immediately said, "I've taken over the control."

Now Wu Taiming is responsible for the communication, so Shi Qi relaxed a little. He took off his headphones and hung them on the side window handle. Shi Qi asked, "Are you from the National University of China? Why don't I know you very much?"

"Teacher, I'm from Shanhang."

"Shanhang, does there be a pair of Airbus on the side of Shanhang?" This made Shi Qi stunned for a moment. How could he remember that Shanhang is now changing the second pair and students in large quantities, but he has never heard of a pair of modified aircraft.

There is no way, it costs a lot to modify the aircraft in the middle, and it doesn’t mean that it’s not the same as if it’s not the technical level of Boeing, and most of the new levels that are positioned are lower than one or two numbers, which makes people feel quite uncomfortable...

"Yes!" When talking about this, Wu Taiming was really disappointed: "It was quite early that the fleet started to change a small number of Airbus. Of course, everyone was unwilling to go there, and then they drew lots. The co-pilot who was nearly 100 draws five, but I drew them!"

A few days ago, Wu Taiming and Lu Xiaoxiao and other friends were caught by Deng Wenjia when they were drinking in Hanjing. The time was when Wu Taiming went to the National University Air Simulator Center in Hanjing for inspection.

He won the prize with an almost 20th chance. Wu Taiming met a few friends and was forced to complain, and then he accidentally drank too much. Then he became even more lucky and was caught by Deng Wenjia.

Because there were only a very small number of modified aircraft models before, Shanhang did not deliberately book simulators in large quantities, so it simply took advantage of the simulators of National University of China. Even the training instructors and accommodation were solved by simulators of National University of China.

National University of China Airlines forced a bunch of planes to optimize its fleet structure. He took the poison himself, but of course he knew that Shan Airlines was at a disadvantage, so he was still a little embarrassed, so he took on all the tasks of training the simulators of Wu Taiming and five other pairs.

Although in theory, CNA Airlines sent some Airbus instructors, captains and a co-sellers to help Shanhang solve the problem of insufficient staff in the early stage, it would take some time to wait for the second and students who had transferred to Airbus to grow into the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the ones who were the one

As for the captain and the technical level upwards, it is easy to solve. When the Airbus fleet is completely stable, you can directly draw the captain from the Boeing fleet to the Airbus side.

It is different from the urgent desire of the co-pilot to turn the captain. When it comes to the captain, the subsequent desire for rotation is slightly lower. After all, even if you become a teacher, the hourly fee will not be much higher, and you still need to bear the additional risk of taking flight. Therefore, there are even some lazy captains who never turn the promotion. Even if the time comes, they are still at the level of a single pilot, and they would rather die than turn the instructor.

Compared to the situation where the number position of the co-pilot's translation is lowered, it is much easier to transfer between the captains, especially Boeing to Airbus, and the losses are very small.

Therefore, many pilots who want to switch models will not choose to change models in the co-pilot stage, which is causing trouble for themselves. Generally, they have to wait until they hire a captain, so they can compare the pressure-free transfer models.

Given that the captain's redirection model did not suffer much, the management of Shanhang felt that there would still be some captains who hoped to redirect the model in the future, and it would be enough to receive these captains.

After all, not everyone has seen it almost like Xu Cang, and has seen it all over all kinds of aircraft. After flying for a long time, Boeing will be the itch of seven years of marriage. There will always be times when they are tired of each other. It is normal for people to change the taste of the aircraft.

In addition, appropriate subsidies can be given to the captains of the early transfer models, which can greatly increase the desire for the captain and the captain's position. Therefore, Shanhang is not very worried about the personnel issues of the captain and the captain's position.

Shi Qi was amused and crying: "Your luck is a little better. But how do I remember this group was originally from that boy Hu Jing?"...

"Brother Hu said there was something happening temporarily, and then the dispatcher caught me flying." Wu Taiming scratched his head: "The company said that we were at a disadvantage when we arranged for our transfer model. We will try our best to arrange flights for us to fly as much as possible, so that we can earn more money, which is also a compensation. It is said that the average number of hours of the Boeing unit in the company is more than 60. According to the company's intention, the average number of hours of the five of us transferred to Airbus can reach 80 hours."

Shi Qi nodded: "Then your company is quite conscientious."

Not to mention anything else, Shanhang is quite generous in treating its employees. It is precisely because of this that most of Shanhang employees are willing to "dedicate" to the company with all their heart.

"I used to think our company is good, but this time it won't work." Wu Taiming deliberately lowered his voice and said to the back cabin: "I heard about Xu Cang. Our company really never protected Xu Cang in a word. Teacher, are you not good about this?"

Shi Qi raised his eyebrows: "Have you spread the news about Xu Cang in your co-pilot circle?"

"It's not much, mainly because Xu Cang is a meritorious pilot, no matter from any angle, it sounds outrageous. Therefore, many people, even if they hear about Xu Cang, mostly just listen to it as a fun thing, and don't think it's the real thing." In the end, Wu Taiming approached Shi Qi and looked at Shi Qi with an extremely curious look: "Teacher, let me know a letter. Is it true that Xu Cang is a meritorious pilot?"

Shi Qi smiled and did not answer immediately. Instead, he raised his hand to turn the passenger seat belt signal light into the automatic position, and then smiled and said, "When you were on the apron just now, those more than 20 old men looked scary. Do you know who they are and what they are going to Hanjing to do?"

Shi Qi knew what those more than 20 people were, but he had no sense of respect. He directly treated the old man with a similar sarcasm.

"I don't know much about this. I just feel that those people are fierce and evil, I'm afraid they are not good people." Wu Taiming pretended to be innocent and "childish words" and actually began to arrange the more than 20 meritorious pilots. In fact, this is not a big deal. It can only be said that Shi Qi made a bad head. Shi Qi was really inconsiderable to the titles of more than 20 people, so Wu Taiming could not associate the three words "old man" with meritorious pilots in any case.

Shi Qi smiled very cheerfully: "Those twenty are meritorious pilots from eight airlines. As for what they are going to Hanjing, they have to go to sue Xu Cang for complaints!"

"Good" Wu Taiming just raised the mineral water and wanted to drink it, but halfway through, he heard Shi Qi talking about the identities of those people, and almost sprayed a sip of water.

But if the water is sprayed out and the electronic system is short-circuited, the problem will be great. So Wu Taiming pressed the water to be sprayed back.

However, most of this hard pressing was sprayed out from Wu Taiming's nostrils, and the scene was very explosive. That was a meritorious pilot. None of the pilots in the entire Shanhang service had the title of meritorious pilot.

No! It seems that Xu Cang is!…

When Wu Taiming thought of describing the group of meritorious pilots as vicious and not good people, he felt that his future was dark.

He pointed to the top board: "Teacher, the cabin sound should only be recorded in the last thirty minutes, right?"

Shi Qi smiled and said, "I don't know this anymore. I heard that some airlines have begun to modify the cabin sound system so that the cabin sound recording can be lengthened. I don't know what state your Shanhang is in?"

"Ah?" Wu Taiming's mind was gone, his fingers hung on the cabin sound cancellation button for a while, but he didn't dare to press it. Finally, he fell into the seat and was already out of mood.

Shi Qi felt happy when he saw Wu Taiming like this. Recently, he was upset and it was still interesting to meet Wu Taiming, a co-pilot.

So, thinking that it was almost done, he was about to explain it to Wu Taiming, but just as he was about to speak, his nose twitched a few times, the smile on his face gradually faded away, and he patted Wu Taiming: "Boy, do you smell anything?"

In the cabin, Xu Cang sat in the middle of the economy class with ordinary passengers, while the more than 20 meritorious pilots who complained were all arranged in the first class and business class in the front.

From the appearance of Shi Lingling to the insistence on going to the Arbitration Court of the General Administration to make a major resolution, Xu Cang has been unable to calm down in the past two days. The feeling of powerlessness in the face of the tide of the times made him feel very uncomfortable.

However, from the initial helplessness and irritability, Xu Cang finally found himself, especially the night before departure that he had counted the stars in the night sky with Qin Xin for a long time. The last wave in his heart had been relieved.

At this moment, Xu Cang didn't care so much about the arbitration decision soon. As long as he strengthened his beliefs, he would overcome difficulties, and he would break through obstacles. What is it like to be lingering in the corner to complain?

At this time, the plane had not yet entered its full cruise time, and the lights in the cabin were still in a dim state. Xu Cang was sitting against the porthole, and there was a middle-aged man sitting next to him. He fell asleep since he sat down. He still had no movement at all. I don’t know if he was asleep.

The departure time is still too early, but this anti-human takeoff moment is to seek benefits for some passengers who don’t care about getting up early, that is, the air ticket prices are generally lower.

The Qizhou Flying Hanjing is not a tourist route and is not suitable for the documents issued by the Bureau not long ago on the release of air ticket price control for some routes. However, the Bureau does not allow airlines to adjust prices at will, which does not mean that the price can only be completely determined. If it floats within a small range, the Bureau will not interfere.

After all, the flight that takes off at around 5 a.m. is the same price as the flight that takes off at 10 a.m. It seems a bit stupid.

That's right, even though the departure time is not good, the attendance rate of this flight is still quite good. When I first got on board, Xu Cang glanced casually, and it was probably more than 70%.

This is definitely a good occupancy rate for the era when aircraft were still high-end representatives in 2000.

At this moment, the sun was still obscuring itself, but the moon was also shy and left, not knowing where, so Xu Cang could only tell the movement of the clouds among the tiny stars to judge the plane was moving forward...

Such a suitable time and environment for sleeping makes the cabin quiet, and you can even hear a few slight snoring nearby. It can only be said that the quality of this group of passengers is still very high, and even their behavior after falling asleep is so implicit.

There was still some time before landing in Hanjing. Xu Cang was clearly the kind of person who liked to sleep in. Getting up early was extremely fatal to him. He thought that he had to sleep all the way to land when he got on the plane, but in fact, Xu Cang was in good spirits and was not sleepy.

However, in the dim cabin, Xu Cang was not good at reading magazines, which was not good for his eyes. So, after hesitation, Xu Cang wrapped the blanket sent by the flight attendant when he was on the ground, intending to close his eyes and cultivate his sleepiness.

However, Xu Canggang adjusted his sitting position. As soon as he closed his eyes, he heard a sound coming from his ears like a drowning person suffocating. Xu Cang's hair suddenly rose and his eyes suddenly opened. He immediately found that the middle-aged man in the seat next to him was pinching his neck, like the little chicken being held, and there were waves of heart-puffing sounds in his throat.

Because the light was too dark, Xu Cang subconsciously thought that this person had gone to sleep. Although it was rare, there were indeed some dreams that someone was pinching his neck and unable to breathe when he was sleeping, but in fact he was pinching himself.

"Sir, sir, let go first!" Xu Cang immediately wanted to pull away the man's hands so that he could breathe.

However, Xu Cang couldn't move at all, his hands were so strong that he could not move at all.

Because the movement of this person was really louder, many passengers who were not asleep or were lightly asleep began to notice this. Not long after, with a burst of rapid footsteps, the flight attendant in the front cabin came to hear the news.

According to regulations, the flight attendant should not leave her seat at this time, but the cabin was so loud that the man's suffocation even came to the workroom in the front cabin, and she couldn't ignore it.

The flight attendant followed the light of the cabin and noticed Xu Cang first. She remembered that Xu Cang was a member of our crew and asked first: "Brother, what's wrong with him?"

"I don't know!" Xu Cang was patting the man at this time while trying to spread the man's hands: "He was like this suddenly! He probably didn't eat anything, and he didn't know if he was sleeping and nightmares."

If this person was eating just now, you could also consider whether he was irritated by eating, but Xu Cang was sure that this person had not been moving and could only be sleeping in a nightmare.

"Come here and pat him, I'll pry his hands open." Xu Cang signaled the flight attendant to help, so that he could free up one hand and spread the man's hands with all his strength.

"Okay!" The flight attendant didn't ask much. However, she did not immediately do what Xu Cang said, but instinctively turned on the reading light on the seat first so that she could see more clearly.

However, as soon as the flight attendant turned on the light, Xu Cang suddenly saw that the middle-aged man was not sleeping at all. He was staring at Xu Cang with his blood-covered eyes, his lips stammering, as if he was about to say something.

The light suddenly appeared, and the scene suddenly appeared. Xu Cang did not expect it. He immediately retreated back and was really shocked, his heart was beating.

But after the initial fright, Xu Cang immediately thought about how it would have become like this if it weren't for the nightmare?...

Almost in the midst of lightning, Xu Cang's mind was filled with inspiration and murmured: "Asthma, he has an asthma attack!"

Perhaps he had an asthma attack without warning in his sleep just now. In panic, he instinctively covered his throat. Moreover, under excessive fear, he could not react. Xu Cang wanted to spread his hand, but he didn't know how to let go of his hand as Xu Cang's strength.
To be continued...
