The use of speed reduction plates is not allowed. Moreover, even if the speed reduction plate is used, it must be the wing or engine pod to contact the ground before the speed reduction plate can be pulled up.

The use of reverse push is also the same principle as the use of speed reducer.

However, in some cases, even if the speed reduction plate is not manually pulled up, the flight spoiler will not get angry, but the ground spoiler will rise under the dual action of the air logic conversion and the slower vehicle of the thrust handle, which will destroy

In this case, the plane needs to be eliminated in a landing and slitting state.

These contents are all on the checklist. Mo Shangyun had no doubts about it. He was worried about another thing, that is, the way Xu Cang fell.

"What are you talking about?" In the cockpit, only Tan Heling was unclear, so: "Xu Cang, what kind of maneuver do you want to do?"

However, Xu Cang did not answer Tan Heling, but glanced at the flap fingering table, found that the flap was already forty, and pointed to the P6 board backwards: "Pull out the jump switch!"

Mo Shangyun looked at it deeply, finally sighed and began to pull out the jump switch according to Xu Cang's instructions.

Tan Heling, who was beside him, heard Mo Shangyun's sigh, and his scalp was numb. He had a premonition, a very bad premonition: "Xu Cang, Xu Cang, what are you going to do?"

After hearing the two sounds of the jump switch being pulled out, Xu Cang took a deep breath, turned his head and looked at Tan Heling, and said solemnly: "I think you should buckle the shoulder straps too."

"What did you say?" Tan Heling's face was filled with fear. The deep uneasiness had hit his heart, and it was expanding rapidly, as if he had returned to the moment when the plane was too high and was about to stall and fall. He didn't

He knew what Xu Cang was going to do, but reason told him that it would be better to follow Xu Cang's words, so he began to tie his shoulder straps in a hurry, and he was even more anxious and angry: "Xu Cang, what do you want to do?"

This time, Xu Cang did not ignore his problem, but while turning left, he lowered his head and looked down the side window and saw Jianchuan Airport located close to the bottom.

"The large slope turns can indeed only level the plane, but the decline cannot be completed." Xu Cang retracted his gaze, and his determination was clear: "If you cannot complete the decline, it means that the slope is still not enough."

Tan Heling's face froze for a moment, then yelled: "It's almost over fifty degrees, isn't this slope enough?"

No matter which angle it is from, the slope of fifty degrees is definitely a large slope, but Xu Cang said it is still not enough.

"It's not enough, it's still not enough, it's far from it!" Xu Cang said indifferently.

At this time, the plane's slope had exceeded thirty degrees, and the alarm sound of BANK ANGLE sounded in the cockpit. However, the sound fell into Tan Heling's ears, like a death-seeking god of death whisper.

At this moment, he finally knew what Xu Cang was going to do. An indescribable horror enveloped Tan Heling. He looked at Xu Cang incredibly: "You want to fly backwards?"...

Xu Cang was still manipulating the plane's slope to continue to increase, and the slope warning sounded a second time. Amid the warning, Xu Cang's unspoken voice fell: "That's right!"

"You crazy man, a large passenger plane can't bear the aerodynamic load of backward flights, and the Boeing manual does not recommend backward flights." Tan Heling shouted: "And, now the fuselage structure of our aircraft is damaged, you just

Are you not afraid of disintegration in the air?"

Before this, Mo Shangyun had already thought of the possibility that Xu Cang wanted to fly backwards 737, so when Tan Heling reacted and exposed Xu Cang's thoughts, he was not very surprised.

But Mo Shangyun's face was not very good. Obviously, from his personal opinion, he did not agree with Xu Cang's approach.

It's too dangerous, it's really too dangerous, it's no different from seeking death! It's just that out of trust in Xu Cang, and he himself has no relatively practical method, so he can only choose the default.

"Do you know why I can survive so many special events?"

Tan Heling was stunned: "What do you mean?"

Xu Cang's eyes were like a rock that had not moved for thousands of years. He gently said: "Because I am living to death!"

At this moment, a small pickup truck was parked on the work path next to the Jianchuan Airport runway. This was a steward. According to the airport's requirements, after the plane landed and was towed by the tow truck, they had already entered the runway and started inspection.

It's right.

However, the plane did not stop after landing not long ago, but once it was pulled up, which made the stewardship vehicle stop stopping on the work path.

"It's just that the plane landed. Is it necessary to conduct a special runway inspection?" complained one of the thin field staff sitting in the right seat.

The colleague who sat on the left looked relatively Yuanlan had no complaints: "They do whatever they asked them to do, how could they complain?"

"You are enlightened, model worker! I'm off work now, please come here for me temporarily." The thin field staff was still complaining. Suddenly, he noticed that his colleague seemed to be looking at the sky and followed him.

: "Is the plane going to land?"

"It's reversed." The fat colleague seemed to have seen something extremely terrible, and the muscles on his face were stiff.

"It's upside down, what's upside down?" The thin field attendant squinted his eyes and searched in the sky. Even though the sun was setting, it would be a bit difficult to look into the sky under the light.

"The plane is coming upside down!" The fat colleague shouted, got out of the car directly, raised his head, and pointed in a direction in the sky: "Look at the plane is flying upside down!"

The thin field staff saw his colleague's behavior and got out of the car in surprise. He raised his head and followed his colleague's guidance. Sure enough, he found the traces of the plane in the sky.

However, this aircraft is a bit strange. Because it is too far apart, it is actually difficult to distinguish the specific state of the aircraft. However, the aircraft's landing gear and vertical tail wing are too conspicuous.

The landing gear of the aircraft in the field of view was actually facing upwards, and the vertical tail was facing downwards, which was really the opposite...

"Flying upside down, flying upside down, how can this plane fly upside down?" The field staff shouted, as if they saw something extremely shocking. He grabbed the fat colleague next to him: "I haven't done that."

You read it wrong, I read it right, this plane is flying upside down."

The fat colleague was also shocked, but his reaction was better than that of the thin field staff, and his emotions were relatively calm, but his constant trembling lips exposed his uncontrollable state of mind.

"This...this." The thin and tall field staff was already approaching aphasia and felt that they could not describe their hearts in words. He just raised his head and followed the trajectory of the plane.

The plane went from his right to the left. He was so shocked that he forgot to turn around to follow the plane. He just kept tilting his head back and finally reached the limit. He went unconsciously.

Then fell down.

Fortunately, the fat colleague held him quickly and quickly, so he did not cause any fall and injury.

Although he was supported by his fat colleague, he actually sat on the ground. At this moment, as the plane's height decreased, more details could be seen, and the size of the plane was getting bigger and bigger in his eyes.

The shock that can be brought is endless.

"You can still fly like this, you can still fly like this." The field staff sat on the ground, repeating this sentence constantly, feeling like they were crazy.

The fat colleague knew that the field staff named Xu Mingjian in front of him had a dream of flying, and he also participated in the recruitment, but he was finally defeated and settled for the second best and worked as a field manager at Jianchuan Airport.

Although he was not successful in participating in the flight recruitment, Xu Mingjian was still actively inquiring about the news about the flight recruitment of an airline during his work. However, there has been no progress over the years.

However, his love for flight has given him some understanding of flight itself. But it is precisely because of his understanding that Xu Mingjian understands more about how terrifying it is to fly backwards 737, which is beyond common sense.

The fat colleague patted Xu Mingjian on the shoulder, and suddenly, something flashed in his eyes. The fat colleague subconsciously looked in the direction where the flash was coming with intuition.

Suddenly, his eyes searched the track for a moment, and found a piece of metal fragment in the area. It was this piece of metal that reflected the sunlight to shine on his eyes.

"Old Xu, get up and take a look. Is there a piece of metal fragment in the area?"

Xu Mingjian was pulled up by his colleagues, and, in a state of mind that he had not recovered from the shock, followed his colleague's instructions to look at the runway area.

Because someone pointed out the direction, Xu Mingjian quickly discovered the metal fragment and immediately looked solemn. However, just as he wanted to answer his colleague, Xu Mingjian's eyes continued to scan along the runway, and the expression on his face was now

It was even stiffer.

"No, no! It's not one piece, it's a lot!"

The fat colleague was stunned, then moved his eyes back along the runway, and his face also became frightened. There were more plane fragments left on the runway in front of the connecting area, and the number was so large that it was just a short time.

It cannot be removed in a while.

"You can't land, this runway must not land." Xu Mingjian forgot about the plane that was still in the sky, but was about to land, quickly returned to the car, picked up the walkie-talkie and started to report the situation to his superiors...

In the tower control room, Director Liu also watched the horror scene of Xu Cang flying backwards, and he could see the details even more clearly with the help of the telescope.

Next to him, the assistant was like a sculpture and said in a daze: "Director, can the plane really fly like this? Is this the crew intentionally flying like this?"

"Otherwise? The plane would not enter this state under normal circumstances." Director Liu put down his telescope, his heart pounding. The shock that Xu Cang gave him was truly unparalleled. This young man under thirty years old was from

The way of behavior is so different from that of ordinary people.

Due to the strong static stability of large passenger aircraft, even for many deviation states, even without intervention, the aircraft can still slowly return to the conventional posture.

It is precisely based on this characteristic that it is difficult for aircraft to enter a complex state of backflight spontaneously, and only artificially deliberately manipulate can achieve such effects.

The assistant can understand this, but he has a question: "Why do the crew fly like this? I remember that almost all large passenger planes are explicitly prohibited from flying backwards? Now the mainstream large passenger planes in the world are designing

I have never considered the need to fly backwards.”

Although the design concept of commercial passenger aircraft pursues safety, it naturally requires economics. In many cases, economics is the first factor.

Because in fact, the structural strength of commercial passenger aircraft is different, for example, the strength of the leading edge of the wing is much stronger than the trailing edge, because in the most common bird hit, it is usually only a hit by the leading edge of the wing, so it only requires

It is enough to strengthen the leading edge of the wing, while the unnecessarily high strength of the trailing edge of the wing can leave a lot of costs.

Therefore, when passenger aircraft manufacturers imagine that large passenger aircraft will not have maneuvers such as backflying, they will naturally not strengthen the aircraft's fuselage to the level of super-maneuverable fighter jets.

If there is no demand, there is no need for assembly and minimize costs as much as possible. This is the concept of commercial passenger aircraft.

Of course, commercial passenger planes are not made of paper. Whether in terms of design or program, Boeing does not want the pilot to fly backwards, but that doesn't mean it's not possible, at least it may be feasible in a short period of time.

"Xu Cang is not a reckless man who is desperate. If he does this, he will make sense."

The assistant's eyes narrowed slightly: "What if he really had time to do anything?"

"What did you say?" Director Liu shouted coldly, his face very ugly. In fact, since the plane resumed flight just now, he had always felt a sense of worry in his heart.

In the 747S2 switch, Director Liu was able to deeply understand Xu Cang's shocking control technology. In the previous communication, Xu Cang also said that the problem was not big, but it was really not big.

But the plane returned to flight, and it was an extremely exaggerated one. Even half of the layman could feel the problem and complete the climb.

Does that mean that Xu Cang and the others have encountered new problems, new and very difficult problems, which will make him choose any problem that he will do whatever he wants?

"Director, do you want to contact the airport emergency committee?" the assistant called softly.

Once you know about the airport emergency committee, the matter will be a big deal. Even if you contact the airport emergency committee, the airport will enter a state of emergency, it will not have a big impact on it. But in the end, it can narrow the scope of the incident as much as possible.

It is his duty as the duty teacher. He has to put the airport in a state of emergency under any circumstances. Then the duty teacher is very easy to do...

"Wait a minute." Director Liu ordered, but he added at the end: "Let the fire department and the medical team take their place, but don't go out and wait for our orders."
To be continued...
