In the cockpit of Lantian 9811, Xu Cang sat silently in the observer's seat. At this moment, the plane had dropped below 14,000 feet. Although it was still higher than 10,000 feet, it was physiologically bearable. Xu Cang also
There is no need to keep a portable oxygen bottle over your mouth and nose at all times.
According to the previous plan, when the plane descended below 10,000 feet, the flight crew would organize people to lift the captain and first officer out to free up seats for Xu Cang's operation.
Moreover, the first-class seats are already full, and the flight crew still needs to convince some first-class passengers to move to the economy class at the back. To be honest, the portable oxygen cylinder really saved lives this time. Without this thing, the whole thing would have been lost.
Flying a plane is dangerous.
Just now, the flight attendant took the aviation safety officer to patrol the lower cabin to check if there were any passengers who were unconscious due to lack of oxygen. Fortunately, as Xu Cang took over the plane, the plane finally changed from a dead climb to a rapid descent.
In this way, as the air pressure altitude decreased, the people in the cabin slowly eased away from the extremely strong discomfort.
Everything seems to be changing for the better, but there is no joy at all on Xu Cang's face. Originally, he expected that he only had to worry about the expansion of the damage to the body, but now there is no new malfunction in the body, but himself
There is something wrong with your body.
Previously, Xu Cang had touched his ear and started to bleed, but Xu Cang was not worried. This was most likely just eardrum bleeding, because there are a large number of capillaries in the eardrum, and bleeding can be expected under sudden changes in air pressure.
Although there will be some effects, tympanic membrane bleeding alone will not affect hearing much, and there will be no obvious sequelae after recovery.
But it's different now. The light yellow liquid mixed in the blood just now is probably the tissue fluid in the inner ear organs, which is a very bad sign.
Maybe the eardrum is perforated!
Judging from the conversation with the flight attendant just now, his hearing has been severely weakened, and I wonder if it will have any adverse effects on subsequent flights.
Of course, rationally speaking, if Xu Cang is given enough freedom, he can complete a normal landing according to standard procedures. However, flying is never an act with absolute freedom, even if an emergency is declared.
The degree of freedom has greatly increased, but it is not infinite.
However, this is indeed far from the point of desperation, but if other failures are superimposed, it will undoubtedly cast a shadow on the return flight in the later period.
I hope there won't be any other problems later. He can try his best to deal with the problem of the plane, but his physical problems are beyond his capabilities.
Moreover, Xu Cang is more concerned about another thing than the ear problem. After all, hearing is not so decisive in flying that it cannot be absent, but vision is different.
The only popular precision approach method in the world is the instrument landing system (ILS), also known as the blind landing system. Although there is a word "blind" in it, it does not mean that you can approach with your eyes closed. What it represents
The word "blind" means that the pilot can not look outside, but he cannot not look at the instruments inside the cabin.
Instrument landing system must rely on instruments!
Xu Cang lowered his head and subconsciously wanted to rub his eyes, but in the end he held back. His eyes felt very swollen from the moment he released the pressure. After the plane began to descend, this symptom still did not get any relief.
.
It is understandable that the eyes are swollen, because of the existence of intraocular pressure. Although he does not understand why the symptoms not only did not relieve after the plane landed, but even became more serious, Xu Cang was actually worried about another possibility, namely the retina.
Bleeding.
Raising his right arm slightly, a small amount of small red blood spots appeared on the right arm, which were formed after capillary rupture. Xu Cang was sure that there were no such things on the skin of his right arm before.
, it just appeared just now.
The boiling of body fluids starts from where the capillaries are concentrated, and the retina perfectly fits this point. If the retina bleeds, Xu Cang really can't even think about it. Maybe it won't cause particularly serious sequelae, after all, the maximum is no more than
Forty thousand feet, but only a short-term impact on vision will be Xu Cang's nightmare.
No pilot can complete the landing without seeing it, not even Xu Cang! The terrible thing is that he is the only pilot on the plane that can be counted on now. If he fails, something terrible will happen.
"Hope everything is fine!"
Just when Xu Cang was worrying alone, he suddenly felt someone coming next to him. He looked up and saw that it was the steward who had arranged the cabin.
The flight attendant did not speak, but pointed towards the cockpit, and then made a gesture to make a phone call. Xu Cang was startled, and immediately picked up the captain's earphones and put them on his head.
"Damn it, I can't even hear the sound from the speaker." Xu Cang was even more worried.
In the cockpit, even without headphones, the speakers will play the sound of the radio channel, which can be heard under normal circumstances. The main reason is that if Xu Cang puts on headphones to listen to things, the pressure of the headphones will make his ears very uncomfortable.
The pain was so painful that it affected Xu Cang's normal work.
Therefore, Xu Cang had been using the loudspeaker to listen to radio calls, but he used the captain's headset microphone to communicate with the controller. In order to ensure that he could hear, he turned the loudspeaker volume almost to the maximum.
I could still tell the difference at first, but unexpectedly, within ten minutes, I couldn't even hear it at the highest volume.
"Blue sky 9811, continue to descend to an altitude of 2,700 meters, and correct the sea pressure to 1011!"
When I usually wear headphones, I don't feel it, but now the headphones are like golden hoops embedded in flesh and blood. Every time the controller speaks a word in the headphones, Xu Cang can feel the subtle vibrations of the headphones that follow.
Enduring the severe pain, Xu Cang replied: "The altitude is 2,700 meters, the corrected sea pressure is 1011, and the blue sky is 9811!"
After saying that, Xu Cang was just about to take off his headphones, but Qianzhou Control continued: "Lantian 9811, Jianchuan Airport has agreed to receive it. Now you fly to route 265, direct to Anshun, and then fly to Xishan along the X92, W133, and A599 routes.
, approach from the direction of Xishan.”
Xu Cang now has an unbearable headache, and he is alone. He has no energy to look through the navigation map, so he just said: "Just give me the waypoint."
"ASH, P554, NOBIN, DJT, and finally Xishan SXS." Qianzhou Control asked: "Blue Sky 9811, please understand the specific situation of the aircraft failure."
Xu Cang silently recited the waypoints, but there were not many. He was familiar with these points and remembered them immediately. This controller was quite sensible. When he was at a high altitude just now, he only thought about how to make room for them.
In the airspace, I didn't grab the crew to ask what happened. They knew their priorities. What I was most afraid of was that the crew was overwhelmed and the controller kept calling on the radio.
It doesn't matter once or twice. I can keep calling like a fly, as if I'm afraid it won't disturb the crew's attention.
"The instrument shows that the left front cargo door of the aircraft opened abnormally, which should be the cause of the pressure release." Xu Cang said: "It is not yet known whether the unexpected opening of the cargo door has caused damage to the aircraft structure."
The controller was silent for a moment, obviously taking notes, and then quickly asked: "Are there any other questions, or what help do we need?"
At this time, Xu Cang was holding his forehead and began to feel unbearable. He quickly stated his needs: "Arrange medical personnel to wait. The captain and co-pilot are already unconscious, possibly due to drastic changes in air pressure and lack of oxygen."
"What?" The controller did not expect that when the cabin was depressurized, the crew also became disabled: "Then you are?"
"I am the person on duty as an overtime crew." Xu Cang took a long breath. At this moment, the plane was already below 10,000, and he could rely on oxygen bottles to breathe: "The other thing is to ask Jianchuan Airport to adjust the brightness of the lighting system to the highest level.
After my aircraft joins the approach procedure, the approach and tower frequencies are merged while other aircraft are radio silent."
Xu Cang must take precautions in advance for possible problems that may arise later. If he really suffers from temporary vision loss in the future, it would be advantageous for him to have the brightest light at the visual stage, and he is only one person.
Other faults are likely to be too busy. Xu Cang doesn't want to spend his remaining energy on converting frequencies and distinguishing from a number of radios whether he is calling him. Moreover, if the radio channel is too noisy, Xu Cang is now
My hearing is really too strenuous.
To be honest, Xu Cang's request is not too much. Generally speaking, an airport the size of Jianchuan must have a backup frequency. It is not difficult to use one to communicate with Xu Cang alone.
This is already Xu Cang's plan for the worst outcome, and Xu Cang is not willing to really get to that point.
"Lantian 9811, can you tell me the reason so that I can coordinate with Jianchuan?" the controller said.
It is normal to turn on the lights, but it is rare to merge frequencies while keeping the radio silent. The controller thought that if Jianchuan Airport asked the reason, he would have to answer.
However, what greeted him was Xu Cang's roar: "Every word I say from now on will have to be explained to you. Is that what you mean?"
The controller did not expect Xu Cang's reaction to be so violent, and quickly apologized: "I'm sorry, I'm sorry, I'm going to communicate with Jianchuan right now."
However, Xu Cang could no longer hear the controller's words. After he finished speaking, he took off his headphones, and the muscles on half of his face tensed together.
People originally rely on the vibration of the eardrum to distinguish sounds. Once the eardrum is injured, the vibrating eardrum will cause Xu Cang great pain when receiving sound.
However, if it was just like this, Xu Cang could barely bear it. However, as soon as he put on the headphones, the pain became more sensitive under the pressure, which had exceeded Xu Cang's tolerance limit. He only felt as if his temples were being stabbed with an awl.
As soon as I entered, I really couldn't say a word.
The controller didn't say anything else. Xu Cang let out a long breath and held his head. His eyes were bloodshot, as if he was becoming more and more confused.
He slowly stretched out his hand, trying to see his palm prints clearly, but what he saw was blurry.
He said what he worried about finally happened.
However, he quickly collected his thoughts, looked at the height of the plane, and said quietly to the flight attendant outside the door: "Is there a space available in the first class cabin?"
The steward saw that Xu Cang's expression was not right, but he still didn't say anything and nodded: "The seats have been vacated. Do you want to move people? I'll ask the safety officer to come over!"
"Let him come over." Xu Cang breathed a sigh of relief, and he was about to take his seat.
At this moment, in the small parking lot in front of the main entrance of the Blue Sky Aviation base building, Luo Yong, Li Rongcheng and Ye Xian were waiting for Yu Fengtian, who was about to go to the tower with them.
Soon, Yu Fengtian came down in a hurry. He was not surprised to see Luo Yong there, but the presence of Li Rongcheng and Ye Xian made him a little confused.
Luo Yong was already tired of waiting. Seeing that Yu Fengtian finally arrived, he grabbed Yu Fengtian and went to the crew car.
Yu Fengtian also knew that the situation was urgent and would wait until he got in the car to discuss anything. Following Luo Yong, Li Rongcheng and Ye Xian also got in the car.
"Master, leave quickly!" Luo Yong greeted.
As the vehicle started, it hurriedly left the base and headed towards the No. 2 security checkpoint.
Not long after driving out, Yu Fengtian pointed at Li Rongcheng and Ye Xian, faced Luo Yong and asked: "Who are they? Why haven't I seen them? Will you come with us?"
"They are employees of Boeing's Asia-Pacific office. The problem this time is a 747, and we don't know for sure. It might be helpful to bring them along."
While Luo Yong was explaining, Li Rongcheng nodded politely to Yu Fengtian, while Ye Xian, who was sitting next to Li Rongcheng, kept looking out the window and ignored Yu Fengtian.
Yu Fengtian did not doubt that he was there, but just hummed, but didn't pay much attention to it, because there were things that concerned him more.
"Luo Yong, I heard something happened to 4724?" Yu Fengtian asked anxiously.
Luo Yong said solemnly: "Relieve the pressure!"
"How to relieve the pressure?" Yu Fengtian knew that his question was a bit low, so he changed his explanation: "Is there something wrong with the boosting system?"
