In the cockpit, after the plane stopped, Richard's hands were shaking, his forehead was covered with beads of sweat, and his whole face was as white as white paper.

From the last 100 meters of the runway, Xu Cang turned out of the runway with thunderous momentum. Under the action of ailerons and differential reverse thrust, he suppressed the aircraft that was about to roll over and finally stopped smoothly.

From the time Xu Cang took the initiative to leave until the plane stopped, it seemed that Xu Cang was dazzled by his romantic skills, but in fact, the duration was only a moment, and it was really a moment of thunder. However, this better reflects 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 man is terrible."

Richard only felt chilled all over. This was not from a physical temperature change but from the shock of his soul.

Before landing, Xu Cang told him that all the engines should be shut down at the moment of landing to save the two PW6000s. Once this decision was made, it was easy to develop mental inertia, and it was not all smooth sailing on the eve of landing, because of that

The strange stall restrained Xu Cang and Richard's energy too much. In fact, one second before landing, neither Xu Cang nor Richard had any basic foresight to change the matter of shutting down the engine.

In other words, at the moment of touchdown and the sound of a tire blowout, Xu Cang sketched out the subsequent use of engine reverse thrust in his mind, directly changing his previous plan.

This way of doing things and this kind of judgment have never been refined. It is impossible for people to think rationally in such a short period of time. Everything is just based on instinct.

Extensive use of the handwheel at high speeds is very dangerous and can easily cause rollover. Richard has a clear understanding of this.

As for using aileron control to suppress the rollover of the aircraft, Richard could also consider it, but relying on differential reverse thrust to reduce the aircraft's turning time is simply beyond Richard's understanding.

Richard understands differential throttle very well. For a pilot of his level, differential throttle is a more useful method. However, differential thrust reverse is really unheard of.

Under foreseeable circumstances, the aileron effect alone at low speed cannot suppress the rollover of the aircraft, so the time to turn out of the runway cannot be too long. After all, if the time is too long, as the speed decreases,

The control surface effect of the ailerons will decrease rapidly, which means that the aircraft cannot be held down.

Therefore, the turn must be completed in an instant, and the large wings of the aircraft will be flattened again by the action of inertia, that is, when the aircraft "does not react".

Looking back now, Xu Cang had to use two hands to control the hand wheel, side stick and reverse push handle, and the control distance was extremely small, which was really fast and precise.

First, use your left hand to press the handwheel, then cross your right hand to hold the side rod, then hold the side rod with your left forearm to secure it, and finally free your right hand to depress the reverse thrust of the No. 2 engine.

The operation here takes only one or two seconds. Is this really something that humans can accomplish?

"Have you thought about using differential thrust reverse since the moment you grounded?" Richard leaned back in his chair, his shirt soaked with sweat. He turned his head and looked at Xu Cang blankly.

"Think?" Xu Cang straightened up: "Do you think I have time to think about it?"

Richard let out a long breath, as if he had lost all strength: "Then you have never mentioned differential thrust before. So are these all improvised by you?"

Xu Cang was also very weak at the moment. The sequelae of his overly excited spirit after he relaxed were extremely obvious. He just wanted to have a good sleep for three days and three nights.

Xu Cang put one hand on the visor and turned his face sideways: "At this time, I never think about it. Following instinct is my way to survive."

"Instinct?" Richard was stunned for a moment: "What an enviable word."

"That's right!" Xu Cang lowered his eyebrows: "So, I am unique."

Richard calmed down for a while, and 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 toward the back cabin: "Go down?"

Xu Cang did not act immediately, but looked gloomy: "Richard, have you never thought about what happened to the stall before landing?"

"Is that really a stall?" Richard was stunned: "I thought my judgment was wrong. But if it was a stall and you pushed the stick so hard, why didn't the plane stall and worsen, but seemed to recover? I pushed the stick before

But it has no effect at all.”

Xu Cang shook his head: "If I guess correctly, this stall is extremely rare. The cause is not the wing, but the elevator."

"Elevator, elevator stalled?" Richard looked a little thoughtful: "Is there any precedent for elevator stalling in large passenger aircraft? I only heard about it happening once in a military transport aircraft when I was serving in the Air Force."

"Elevator stall. It is indeed rare, but only elevator stall can explain everything we encountered." Xu Cang organized his words slightly: "I had thought about the stick shaker warning during the dive before. At that time, the aircraft was very fast.

is large, the angle of attack is actually kept very small, but still

A stick shake warning was generated. After that, I tried to eliminate the warning by pushing the stick, but the result was in vain. On the eve of landing, we encountered the same situation. Of course, there was no stick shake this time, but from the nose of the aircraft,

If the droop changes, you can basically tell that the aircraft is stalling."

"Your handling of the stall is still the push rod, and the feedback is still ineffective." Xu Cang's words contained a hint of anger: "During the dive before, this was a situation rarely encountered by large passenger aircraft, and the aerodynamic performance was relatively complex.

There may be some special situations that may not be representative. However, if it is special once, it is not certain twice. There must be some inevitability."

Richard pursed his lips: "If the elevator stalled, it can indeed perfectly explain the various abnormalities encountered before."

The speed of the aircraft is usually limited to wing stall. In this case, it is indeed a standard procedure to use the push rod to recover from the stall. However, if the elevator stalls, the push rod is not a disposal procedure, but a reverse operation.

.

When the elevator stalls, the recovery procedure is to use the stick.

Both are stalls, and just because they occur in different locations, the handling procedures are completely different.

However, why do aviation schools, airlines or almost all other flight training institutions only perform ejector control to deal with stalls? This illustrates from the side how rare elevator stalls are, so rare that they are not worthy of being treated as a separate event.

List the situations.

At least neither Xu Cang nor Richard has heard of anyone encountering an elevator in the field of large passenger aircraft. Even if it extends to the military field, there are only a handful of examples.

Why the probability of elevator stall is much smaller than that of wing stall, there are many reasons involved. Take the stall caused by ice as an example, before the elevator freezes, the ice on the wing will only become more serious, so when the elevator

Before stalling, the big wing has already stalled, so naturally it cannot be encountered.

However, in the natural environment, the probability of elevator stalling is indeed too small.

After Richard heard about the possibility of elevator stalling, he didn't worry too much about whether it was true or not, but thought about what it would mean if it was true.

"Someone is tampering with someone?" Richard's face was very ugly, so gloomy that he almost dripped water.

Rather than believing in the extremely small probability of natural occurrence, man-made causes are obviously more worthy of consideration.

Xu Cang snorted: "If so, these people are very scheming."

Before that, Xu Cang had expected that some people, or some people who didn't want the people from the Alpine Manor to come back, would probably do something to him. Therefore, he asked Richard to arrange some private security. As a result, everything was calm before takeoff. Then

Shi Xu Cang thought he was overthinking.

But now it seems that these people are really vicious.

The above-board assassin was indeed too conspicuous. Instead, he was unknowingly and unknowingly tampering with the aircraft, and he did so in an extremely clever and secretive way. In some way, he caused the elevator to stall. Such a stall is actually automatic, even if

Many experienced pilots have never thought of the possibility of elevator stall.

Just like Richard, he fell into this psychological trap before and almost crashed the plane on the runway.

To be honest, this method is really suitable for experienced pilots like Xu Cang and Richard. If there were some average pilots sitting on it, who didn't hear the stick shake warning and saw the nose of the plane drooping, they wouldn't be able to do it at all.

Don't think about it, just take the pole and nothing will happen.

That is to say, pilots like Xu Cang and Richard thought too much and thought too far. As a result, their cleverness was mistaken for their cleverness, which almost caused a catastrophe.

The psychological game involved is extremely sinister and cruel.

Moreover, the wind and snow in the Alps are extremely strong. Even if it is traced later and the cause is found to be the elevator stall caused by ice on the plane, it is still in line with environmental factors and it is unlikely to link the plane crash with man-made causes.

"Did they tamper with the anti-icing fluid?" Richard became more and more angry as he thought about it, but also became more and more strange: "But the anti-icing fluid should be fine. Didn't you check it before taking off?"

Xu Cang snorted: "These people are very thoughtful. I'm afraid they have erased the traces now. If we crash, the cause of the plane accident will only be the severe ice accumulation on the plane caused by the environment. It has nothing to do with them at all. What a good trick."

.”

"Damn it, let me go down and take a look." Richard had nothing to think about now, but he just wanted to go down and see what was going on with the plane's elevator.

At this moment, the passenger elevator waiting outside the airport came staggering over. The plane itself was not parked on the runway, and the ground was completely covered with snow. Judging from the tracks made by the wheels, it must have entered the grass.

The passenger elevator car didn't know 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 transmission trucks also came over.

"Go down and have a look!"

Richard took out the down jacket that he had already prepared and wrapped it in it from the cloakroom, then opened the front door of the plane by himself. As soon as he opened the door, the roar of the wind and snowy mountains outside almost made Richard lose his balance.

However, at this time, there was a surge of anger in Richard's chest. He was not afraid of the wind and snow, so he stepped on the ice and snow on the passenger elevator and went down.

As soon as we got off the plane, a tightly wrapped cargo handling staff came over and said, "Captain, there is nothing wrong with the plane. If there is no problem, we will start unloading the cargo."

Richard glanced at the manor in the distance, where many people looked over through the windows, and there was hope for their survival on the plane.

"It's a flat tire. It's not a big problem. Remember to put the wheel chocks in place. If the wind is strong, don't let the plane move." Richard ordered.

As soon as he opened his mouth, he took a mouthful of snow and couldn't keep his eyes 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 effective.

Without any heating supplies, I can't bear it at all.

"I know, I know." The loading and unloading staff nodded hurriedly: "The wheel chocks have been put in place, let's start unloading the cargo. Thank you, Captain, thank you Captain."

Richard's coming over this time gave them a chance to survive. The loading and unloading staff wanted to kowtow to Richard to thank him.

"Go, go."

After the loading and unloading staff thanked Richard, they called to their colleagues and shouted: "Start unloading, pay attention to the time, every fifteen minutes."

The outside temperature is too low, and the exposure time cannot be too long, otherwise they may suffer from frostbite. The loading and unloading personnel are divided into two groups, one group comes out, and the other group rests in the room to keep warm. A rotation cycle of fifteen minutes is used to maximize the protection of the loading and unloading personnel.
