If the pressure relief was just caused by the unit's control error or the aging of some parts, Yu Fengtian would not be so nervous. Pressure relief incidents occur every year in domestic civil aviation, and they can usually be handled in a low-key manner without causing any major social consequences.

public opinion.

Even if the authority wants to impose penalties, as long as the human factors are not too outrageous, most of them will not be too harsh. Under normal circumstances, if the aircraft depressurizes, the control authorities will usually notify the relevant companies and will not ask company representatives to go to the tower.

Help. Because depressurizing an aircraft usually does not cause control problems.

When the plane descended to 10,000 feet, I felt a little uncomfortable breathing, but the rest was basically the same as a normal flight.

What Yu Fengtian was worried about was another thing. Ever since his secretary informed 4724 that something had happened and the tower asked them to help, his mind could not help but recall the reason why Xu Cang confronted him yesterday. S2 switch!

"Is there really something wrong with that thing?" Every time Yu Fengtian thought about this possibility, he felt so shaken that he couldn't calm down at all.

As long as it is really caused by the S2 switch, then his position as Vice President of Maintenance will basically be lost!

Luo Yong was about to speak, but his cell phone rang. He saw that the number belonged to his secretary. He thought there was some latest news, so he answered it immediately: "What do you mean, is there something going on?"

"We just received a call from the Qianzhou District Adjustment Office, confirming that 9811 will arrive and return via the direction of Xishan. At the same time, according to the crew, it is strongly suspected that the front cargo door of the aircraft opened abnormally, causing the aircraft to depressurize. It is currently unknown whether there is any collateral damage.

.”

After the secretary said this, Luo Yong looked at Yu Fengtian beside him in disbelief, his lips trembling: "The cargo compartment door is open!"

"What!" Yu Fengtian almost jumped up and his eyes almost popped out: "How did you open it? How did you open the cargo door?"

However, the secretary did not finish what he said. He continued: "Luo Yong, and Qianzhou Control received news from the crew that the captain and co-pilot on duty are already in a coma and incapacitated state. The crew is currently controlling the plane. I checked.

Wait, there are only two people in the crew of flight 9811, one is the flight attendant and the other is Xu Cang! I think the one who is controlling the plane is..."

Luo Yong didn't even listen to the secretary's words. He just turned his head and looked at Yu Fengtian who was bewildered, and let out a burst of sarcastic laughter. This laughter was for Yu Fengtian as well as for himself.

"Yu Fengtian, I feel like you are going to die!" Luo Yong said suddenly.

"The crew is incapacitated. The captain and co-pilot are both unconscious. Now Xu Cang is controlling the plane back." Luo Yong's chest rose and fell sharply: "You'd better write your resignation later. It'll be more dignified."

Regardless of whether Flight 9811 can return safely, as long as it is proven that the abnormal opening of the cargo door was caused by the S2 switch, it will be impossible for Yu Fengtian to sit down as the vice president of maintenance again.

Of course, the reason for the abnormal opening of the hatch is not limited to the S2 switch. There may be other factors. However, Xu Cang impressed Luo Yong so deeply that Xu Cang even explained the principle of the abnormal opening of the hatch.

There is no reason not to lean on the S2 switch.

"Impossible!" Yu Fengtian shouted flatly: "How can he fly a 747? It's all nonsense!"

"Why can't he fly a 747? You don't really think he is an ordinary pilot, do you?" Luo Yong was also anxious at this time. Xu Cang was indeed a little ignorant before, and his behavior was not in line with his past habits. But

, Yu Fengtian definitely has an unshirkable responsibility for the current situation where Xu Cang and Blue Sky Airlines are at odds with each other.

In Yu Fengtian's eyes, Xu Cang is just a pilot. There are just a lot of pilots in the aviation school and the company. He can be accommodated if necessary. As a result, he handles Xu Cang's affairs with disgusting arrogance.

Angry people will become dissatisfied.

Luo Yong gritted his teeth and said: "Some time ago, my master asked me to transfer Xu Cang from the Boeing fleet to the Airbus fleet. Do you know why?"

Of course Yu Fengtian knew that the master Luo Yong was talking about was Airbus captain Jin Fuli, but Jin Fuli did not like to see Luo Yong and was not willing to admit him as his apprentice.

Yu Fengtian kept silent and just stared at Luo Yong.

"My master told me that during the simulator training, this kid calculated the best glide trajectory more than 20 nautical miles away in the presence of high-altitude variable winds, and it was accurate!" Luo Yong snorted:

"He can even fly an Airbus, so why can't he fly the 747, which is also a Boeing series?"

Before Yu Fengtian could react, Ye Xian, who had been sitting in the back casually, suddenly shouted: "Even if the wind speed of the simulator changes linearly, if you want to always correct the optimal speed, the amount of calculation is too large, and mental calculation is impossible.

Completed.”

"Why can't it be completed? My master saw it with his own eyes." Luo Yong said firmly: "There must be a training video from that time on the shelf in the fleet inspection room!"

Hearing this, Li Rongcheng's right hand clenched tightly involuntarily. If what Luo Yong said was true, then Xu Cang's value would exceed his estimate. Because the problem with the Boeing 777 verification a few days ago was due to the

The flight crew's mental calculation of the descent trajectory went awry when the engine failed.

However, even though Luo Yong was so sure, Ye Xian still didn't believe it: "It is impossible for humans to have such mental arithmetic ability!"

Luo Yong hummed: "Then you can ask him yourself, if he can come back!"

After saying that, Luo Yong looked at Yu Fengtian, whose face was as gloomy as water: "You'd better pray that there is no problem with the S2 switch, otherwise, you will be left without food!"

When he said this, the corner of Luo Yong's eye glanced at Li Rongcheng behind him. Li Rongcheng caught the fierceness in Luo Yong's eyes and couldn't help but curse in his heart: "Damn it!"

If there is really a problem with the 747's S2 switch, then the notice issued by Boeing must be ignored. If you realize the problem, but issue a specious technical notice, you will definitely be in trouble later.

Nowadays, the Boeing 777 has already caused a lot of trouble for the headquarters. If it gets involved in another lawsuit, it will be difficult to handle.

Suddenly, Li Rongcheng had a huge headache!

The only thing I hope for now is that Xu Cang can return safely. As long as he is fine, everything will be easy to discuss.

In the cockpit of Lantian 9811, the flight attendant called the aviation safety officer and a male flight attendant in the rear cabin to carry the captain and first officer out.

Before carrying the captain, the flight attendant specially found a blanket to wrap the captain's upper body, covering his shirt which was mostly stained with blood. He also wiped the blood stains on the captain's face with a wet towel to avoid having to go outside.

, causing another commotion in the first class cabin.

After the cockpit was cleared, Xu Cang hurriedly sat in the left seat, which was the place he was most accustomed to.

As soon as he sat down, Xu Cang began to enter the subsequent route. Since the captain and co-pilot were both present, it was not convenient for him to enter the CDU, so he only temporarily entered the first waypoint and let the plane fly first.

"P554, NOBIN" Xu Cang muttered while modifying the parameter settings on the CDU.

He not only had to key in the subsequent route, but also needed to select the subsequent approach procedures and prepare for the approach. It didn't even take half an hour for them to land.

There are some differences between the CDU of the Boeing 747 and the (M) CDU of the Boeing 737. Xu Cang has not flown the 747 for a long time, so he is indeed a little stymied at the beginning of the input. However, the basic principle of this thing is the same. After a little thought, it is almost the same.

I can also figure it out.

Soon, Xu Cang entered the follow-up route and was about to enter the entry procedure when he heard a burst of footsteps behind him, and then a person stepped into the right seat, it was Xia Shuyue.

Previously, Xu Cang told Xia Shuyue to come over if the altitude was less than 10,000 feet, but the steward still remembered it.

After Xia Shuyue sat down, the steward asked from behind: "Then I've closed the door?"

Xu Cang didn't say anything, but gave the steward a thumbs up.

"Is there nothing going on in the cabin?" Xu Cang kept his head down as he spoke, without even looking at Xia Shuyue.

Xia Shuyue was just about to answer, but she heard Xu Cang say again: "Speak louder."

Xia Shuyue glanced at Xu Cang's ears. There was already some blood scab on the outside of the ear canal, which looked very ferocious and terrifying. However, she still calmed down, knowing that she would not ask or say any unnecessary words at this moment, as long as she obeyed

Just Xu Cang.

"The flight attendant led the safety officer to patrol the cabin just now. It should be nothing serious. Some of the unconscious people also put on oxygen masks." Xia Shuyue asked cautiously: "Brother, what do you need me to do?"

Xu Cang pointed to the co-pilot's earphone: "You are responsible for talking to the control. If I need it, you can transfer it to me. Then, if necessary, I will tell the control what I said. Don't worry about the aviation terminology, just follow normal

It’s the same as communicating.”

"Oh!" Xia Shuyue was obedient and hurriedly put on the co-pilot's headset upright. However, as soon as she put it on, Xu Cang lightly knocked her head: "Don't wear it so tightly, put the left earphone on

Open your ears or you can't hear me clearly!"

Pilots never wear headphones on both ears. They usually expose one ear to facilitate communication in the cockpit. Only laymen cover their ears tightly.

"That's it!" He hurriedly exposed his left ear, and then asked Xu Cang: "Brother, is that like this?"

"Well!" Xu Cang still lowered his head while inputting CDU, but kept saying: "Don't be nervous, you."

As soon as you finished speaking, Xu Cang's fingers that were pressing the keys suddenly stopped, and his whole body seemed to be frozen, staring blankly at the CDU screen.

Soon, Xu Cang went crazy and increased the input speed to an infinitely high speed, as if something was chasing him.

However, in the past, methodical speed was the best, fast enough and guaranteed to be accurate. But now, when we focus on speed, we often make mistakes.

Next to her, Xia Shuyue really couldn't understand the operations on the CDU, but she could understand that Xu Cang often made repeated changes in the same input field. This was a sign of making mistakes in a hurry.

Originally Xia Shuyue was unwilling to disturb Xu Cang, but after seeing Xu Cang make mistakes again and again, Xia Shuyue still reminded her: "Brother"

However, just when Xu Cang was about to type in a positioning point, Xu Cang stopped suddenly under Xia Shuyue's voice. At this moment, the air seemed to freeze.

Suddenly, a round blood droplet fell down, hit the LCD screen of the CDU, and exploded in all directions.

Xia Shuyue trembled all over, she clearly saw the drop of blood. At this moment, Xu Cang slowly raised his head and finally turned his face towards Xia Shuyue.

But when Xia Shuyue saw Xu Cang's face clearly, she couldn't help covering her mouth with her hands. She saw that the white part of Xu Cang's eyes had been replaced by dazzling blood, and the blood and tears falling from the corners of his eyes were even more shocking.

mind.

Xu Cang was sure that he was facing Xia Shuyue now, but he couldn't see it!
Chapter completed!
