Chapter 331 Who is it?
In the cockpit, after the plane stopped, Richard's hands were shaking, his forehead was covered with fine beads of sweat, and his whole face was as pale as white paper.
From the last hundred meters of the runway to when Xu Cang turned off the runway with lightning speed, with the help of ailerons and differential thrust reversers, he suppressed the plane that was about to roll over and finally stopped it steadily.
From the time Xu Cang took the initiative to leave to the time the plane stopped, it seemed that Xu Cang's operation was elegant and dazzling, but in fact, it only took a moment, and it was really a thunderclap. However, this can better reflect Xu Cang's incomparable adaptability and control ability.
In fact, it was only after the plane came to a complete stop that Richard began to gradually understand Xu Cang's series of operations.
"It's terrible, this person is terrible."
Richard just felt cold all over, which was not from the physical change of temperature but from the shock of the soul.
Before landing, Xu Cang told him that he would shut down all engines at the moment of touchdown to save the two PW6000s. Once this decision was made, it was easy to form mental inertia, and the eve of landing was not smooth sailing. Because the strange stall tied up too much energy of Xu Cang and Richard, in fact, one second before landing, Xu Cang and Richard did not have the basic foresight to change the matter of shutting down the engines.
In other words, the moment Xu Cang touched down and heard the tire burst, he had already outlined the subsequent use of engine reverse thrust in his mind, which directly changed his previous plan.
This way of doing things, this ability to judge, has never been carefully crafted. Such a short time makes it impossible for people to think rationally, and everything is just based on instinct.
It is very dangerous to use the hand wheel extensively at high speed, and it is extremely easy to cause rollover. Richard has a clear understanding of this.
As for using aileron control to suppress the aircraft's rollover, Richard could consider it if he were given the opportunity, but relying on differential reverse thrust to reduce the aircraft's turning time was simply beyond Richard's understanding.
Richard understood differential throttle very well, and it was a relatively easy-to-use tool for pilots of his level, but differential reverse thrust was something he had never heard of.
Under foreseeable circumstances, the aileron effect at low speed alone cannot suppress the aircraft's rollover. Therefore, the time to turn out from the runway cannot be too long. After all, if the time is too long, as the speed decreases, the aileron control effect will decrease rapidly, and the aircraft will not be able to be suppressed.
Therefore, the turn must be completed in an instant, using inertia, or so-called "preventing the aircraft from reacting" to flatten the aircraft's wings again.
Now thinking back, Xu Cang had to use both hands to control the handwheel, side stick and reverse thrust handle, and the operation interval was extremely small, which was really fast and precise.
First, press the handwheel with your left hand, then cross your right hand to support the side stick, then use your left forearm to support the side stick to fix it, and finally free your right hand to press down the reverse thrust of the No. 2 engine.
The operation here only takes one or two seconds. Is this really something that humans can accomplish?
"Have you decided to use differential thrust reverse from the moment you touched down?" Richard leaned back in his chair, his shirt soaked with sweat. He turned his head and looked at Xu Cang in a daze.
"Think?" Xu Cang straightened up: "Do you think I have time to think?"
Richard let out a long breath, as if he had lost all his strength. "You clearly didn't mention differential thrust reverse before. So you came up with all this on the spur of the moment?"
Xu Cang was also very weak at this moment. The sequelae of his overly excited spirit after relaxation were extremely obvious. He now just wanted to have a good sleep for three days and three nights.
Xu Cang placed one hand on the sunshade and turned his head: "At this time, I never think about it. I just follow my instinct. That's my way of survival."
"Instinct?" Richard was stunned for a moment: "What an enviable word."
"That's right!" Xu Cang lowered his eyebrows: "So, I am unique."
Richard paused for a moment, then a wry smile appeared on the corner of his mouth: "Yes, you are unique."
After a while, Richard regained some strength, but he also felt the biting cold. After the engine was shut down, the components could not work, and naturally the temperature in the cabin could not be adjusted.
Looking at the vast expanse of white outside, Richard pointed towards the rear cabin and said, "Go down?"
Xu Cang did not act immediately, but his face was gloomy: "Richard, have you ever thought about what the stall before landing is?"
"Is it really a stall?" Richard was stunned. "I thought I misjudged it. But if it was a stall, why didn't the plane stall more aggravated when you pushed the stick so hard? Instead, it seemed to have recovered? I pushed the stick up before but it didn't work at all."
Xu Cang shook his head: "If I'm not mistaken, this stall is extremely rare. The cause is not on the wing, but on the elevator."
"Elevator, elevator stall?" Richard looked thoughtful. "Have you ever encountered an elevator stall in a large passenger plane? I only heard of a military transport plane encountering one when I was serving in the Air Force."
"Elevator stall... is indeed rare, but only elevator stall can explain everything we encountered." Xu Cang organized his words a little: "I thought about the stick shaker warning before when I was diving. At that time, the aircraft speed was very high and the angle of attack was actually maintained very small, but the stick shaker warning still occurred. After that, I tried to eliminate the warning by pushing the stick up, but to no avail. On the eve of landing, we encountered the same situation. Of course, there was no stick shaker this time, but from the drooping changes in the aircraft's nose, it can be basically determined that the aircraft was stalled."
"You still pushed the stick to deal with the stall, but the feedback is still ineffective." Xu Cang's words contained a hint of anger: "This is a rare situation for large passenger aircraft during the dive. The aerodynamic performance is relatively complex, and there may be some special situations that may not be representative. However, if it is special once, it may not be the case twice. There must be inevitability."
Richard pursed his lips and said, "If it is the elevator stall, then it can perfectly explain all the abnormalities we encountered before."
The speed of the aircraft is usually limited to a wing stall, in which case stick push is indeed the standard . However, if it is an elevator stall, then stick push is not a procedure, but a counter-operation.
In the event of an elevator stall, the recovery procedure is to pull the stick.
Both are stalls, but the handling procedures are completely different just because they occur in different locations.
But why do flight schools, airlines, and almost all other flight training institutions only use stick push to respond to stalls? This shows how rare elevator stalls are, so rare that they are not worth listing as a separate situation.
At least neither Xu Cang nor Richard had ever heard of anyone encountering elevator problems in the field of large passenger aircraft. Even if it expanded to the military field, there were only a handful of examples.
Why is the probability of elevator stall much lower than that of wing stall? There are many reasons involved. Take stall caused by ice as an example. Before the elevator freezes, the wing will be more seriously frozen. Therefore, before the elevator stalls, the wing will have already stalled, so it is unlikely to happen.
However, in a natural environment, the probability of an elevator stall is very small.
When Richard heard about the possibility of an elevator stall, he didn't dwell so much on whether it was true, but rather on what it would mean if it was.
"Is someone tampering with something?" Richard's face looked extremely ugly, so gloomy that water seemed to be dripping out of it.
Rather than believing in the extremely small probability of natural occurrence, human-caused causes are obviously more worthy of consideration.
Xu Cang snorted: "If that's the case, these people are really scheming."
Before this, Xu Cang had anticipated that someone or some people did not want the people from the Alpine Manor to come back, and would probably do something to him. Therefore, he asked Richard to arrange some private security, but everything was calm before takeoff. At that time, Xu Cang thought he was overthinking.
But now it seems that this group of people are really sinister and vicious.
Sending assassins openly would be too conspicuous . Instead, they tampered with the plane without anyone noticing, and the tampering was extremely clever and covert. They caused the elevator to stall in a certain way, which was actually a counter-intuitive stall. Even many experienced pilots would not have thought of the possibility of elevator stall.
Just like Richard, he fell into this psychological trap before and almost caused the plane to crash into the runway.
To be honest, this method is really suitable for experienced pilots like Xu Cang and Richard. If the pilot sitting on it is an average pilot, he didn't hear the stick shaker warning, and saw the nose drooping, he would not have to think about it and just hold the stick, and nothing would have happened.
In other words, pilots like Xu Cang and Richard thought too much and too far ahead, but ended up being too clever for their own good and almost caused a disaster.
The psychological game involved is extremely sinister and cruel.
Moreover, the wind and snow in the Alps are extremely strong. Even if the cause is found to be elevator stall caused by icing on the plane, it is consistent with environmental factors and it is unlikely to link the plane crash to human factors.
"Did they tamper with the anti-icing fluid?" Richard was getting angrier and angrier as he thought about it, but also more and more puzzled. "But... the anti-icing fluid should be fine. Didn't you check it before takeoff?"
Xu Cang snorted: "These people are meticulous. I'm afraid they have erased all the traces now. If we crash, the cause of the accident will only be the severe ice accumulation on the plane caused by the environment. It has nothing to do with them. Good trick."
"Damn it, I'll go down and take a look." Richard didn't have anything else to think about now, so he planned to go down and take a look at the condition of the plane's elevator.
At this moment, the passenger elevator waiting outside the airport drove over in a lurching manner. The plane itself did not stop on the runway, and the ground was completely covered with snow. Judging from the tracks left by the wheels, it should have entered the grass.
The passenger elevator had no idea of the road conditions, so it could only slow down and move slowly.
After a few minutes, the passenger elevator finally approached the plane, and at the same time, two unloading transport vehicles also came over.
"Go down and take a look!"
Richard took out the down jacket he had prepared from the cloakroom and put it on, then opened the front cabin door of the plane. As soon as he opened it, the wind and snow outside roared in, almost making Richard unable to stand steadily.
However, at this time, Richard was so angry that he was no longer afraid of the wind and snow. He walked down the passenger elevator on the ice and snow.
As soon as I got off, a tightly wrapped cargo loader came running over and said, "Captain, is the plane okay? If it is, we will start unloading."
Richard glanced at the manor in the distance, where many people were looking over here through the windows. Their hope of survival was on the plane.
"It's just a flat tire, not a big deal. Remember to put the wheel chocks in place. The wind is strong, so don't let the plane move." Richard ordered.
As soon as he opened his mouth, he ate a mouthful of snow, and his eyes could hardly open. He finally understood why everyone here relied on supplies from the outside world. Even if he was wrapped in a thick down jacket, it was still not very useful. Without heating supplies, he could not bear it at all.
“Yes, yes.” The loader nodded hurriedly, “The wheel chocks have been put in place, so let’s start unloading. Thank you, Captain. Thank you, Captain.”
Richard's coming here this time gave them a chance to survive. The loaders wanted to kowtow to Richard to express their gratitude.
"Go ahead, go ahead."
After thanking Richard, the loader called his colleagues and shouted, "Start unloading. Pay attention to the time. The shifts are every fifteen minutes."
The temperature outside is too low, and the exposure time cannot be too long, otherwise there is a possibility of frostbite. The loading and unloading personnel are divided into two groups, one group goes out, and the other group rests and keeps warm in the house. The rotation cycle is 15 minutes, which can maximize the protection of the loading and unloading personnel.
Perhaps because of the urgent need for supplies, these loaders and unloaders worked extra hard.
Probably because of the lack of fuel, there was only one small truck carrying goods. When the truck was full, some people ran directly into the manor with the goods. When they ran into the manor, they could faintly hear cheers coming from inside.
After Xu Cang put on his clothes and came out, he felt like he was in an ice cellar. He was sweating when he landed. When the components were opened, there was still some heating inside the plane. When he came out, cold wind rushed in, and he felt that the sweat was about to freeze. It was extremely uncomfortable.
After he got off the passenger elevator, he happened to see the busy working scene of the loaders and unloaders.
At this moment, two tall men came over from the distant tower. They were Alandi and Asiris.
Aixiris witnessed Xu Cang's drift-like operation on the control tower. He walked closer and exclaimed: "Mr. Xu, your skills are really impressive."
Xu Cang frowned: "Who are you?"
"Oh, I'm Asiris Stuart, the president of British Airways."
Alandi, the narrator, also introduced himself: "CEO of Luoluo, Alandi."
"Nice to meet you." Xu Cang nodded slightly as a greeting.
Aisiris was obviously more excited to see Xu Cang. Just when he was about to say something, he was gently pushed by Alandi, so he immediately came to his senses: "Sorry, Mr. Xu, I have something to do. Let's talk later."
After saying that, Asiris walked to the front cargo hold, shouted to the stevedores inside to send them away, and walked into the cargo hold from the conveyor belt. About a minute later, when he came out, he was holding a black square box in his hand.
Xu Cang took a glance and saw that there was a combination lock on the box, so the protection measures were very thorough.
"Are there any interesting things?" Xu Cang chuckled.
Asiris returned to Alandi and laughed: "Just some small gadgets, to prevent accidents, to prevent accidents."
Xu Cang raised his eyebrows and said, "I advise you to keep it locked up. The supplies we brought this time are enough for emergency use. If the time comes, showing those things will not be a way to protect yourself, but a way to bring disaster. Even if you pampered gentlemen have weapons, I guess you won't have much combat effectiveness."
Xu Cang's words were very straightforward, but Alandi and Aisiris did not feel annoyed at all because Xu Cang had poked the contents of their boxes. Alandi just laughed and said, "I hope so too."
"The supplies are provided according to the minimum standard for survival, not for you to enjoy. Pay attention to your own portion." Xu Cang snorted coldly.
If everyone can distribute the amount according to the plan, then everyone can survive. However, Xu Cang is afraid that those who are used to a wealthy life will be greedy and rob others of their supplies, causing chaos.
In this situation, if lethal weapons were used, it would be easier to intensify the conflict.
Xu Cang's words were a warning to the wealthy and powerful people represented by Alandi and Asiris to strictly abide by the quota standards and not have any unreasonable expectations.
Alandi nodded slightly: "Of course!"
Xu Cang wanted to say something, but suddenly he heard a roar like a volcanic eruption from not far away: "Who is it!?"
The three of them were startled and looked in the direction of the sound. Richard was standing under the tail of the plane, looking up. In his sight, the elevators of the plane were already covered with ice, which was much more serious than the wings.
Xu Cang's eyes turned cold: "Someone really did something!"
