Return to 2000: Captain of the Great Powers

On the control tower of Jianchuan Airport, the assistant looked at the plane floating in mid-air in an extremely strange upward posture above the sky, and his heart was already surrounded by endless fear.

As we all know, the 737 cannot hover in the air.Now the pitch-up attitude of the plane is obviously abnormal, and even the assistants are not professional flight personnel can detect the seriousness of the problem.

In this attitude, the aircraft will definitely stall, and then the lift on the wings will gradually lose, and the aircraft will fall straight down with a free landing attitude.

"director!"

The assistant has also been in the industry for many years, but he has never seen such a scene of an airplane. This picture is deeply engraved in the assistant's mind like a brand.

Just when Director Liu was almost hopeless, the plane that was almost hovering in the air suddenly moved.It deflects to the left with an unbelievably exaggerated slope.

"Moved!?"

Director Liu's muscles trembled violently, and a little brilliance finally appeared in his eyes.

"There is still a way!"

At this moment in the cockpit, Xu Cang finally made his own response on the eve of the deep stall.He only has one chance, as long as he doesn't grasp it, he will die without a place to bury him.

Xu Cang suddenly made an extremely steep turn with a slope of more than [-] degrees. Under this effect, the red and black speed belt of the plane immediately began to move downward.However, the plane did not continue to go up, but the speed of the plane was still switching back and forth at the top of the red and black speed bands, and the steering wheel was always in a state of chattering from time to time.

Under the condition of artificial restoration of hydraulic pressure loss, the control wheel of the aircraft is very, very difficult to operate. Under the action of the chattering logic of the control wheel, Xu Cang can't even grasp it.

However, Xu Cang still tried his best to hold the steering wheel tightly. He knew that as long as there were few mistakes, God would not give him another chance.

Beside Xu Cang, Tan Heling really did not expect Xu Cang to make a steep turn.This can indeed interrupt the problem of the plane continuing to rise and resulting in a sudden drop in speed. However, they can't keep turning like this.

"The plane's altitude didn't go down, and its speed couldn't increase, what's wrong?" Tan Heling yelled.

From Tan Heling's point of view, Xu Cang's way of making a steep turn is tantamount to drinking poison to quench his thirst, and it can't fundamentally change the current plight of the plane.

However, Xu Cang did not answer Tan Heling's question at all, and he had already outlined all the subsequent steps in his mind.He doesn't need other people's suggestions, corrections, and doubts from others, as long as he does what he thinks.

"The landing gear handles, pull them all out!" Just when Tan Heling didn't understand Xu Cang's thoughts, Xu Cang had already started to issue new instructions.

In his vision, there is already a possible landing method.But before landing, he had to clear as many obstacles as possible for his landing, including problems with the landing gear.

The reason for the go-around just now was that the left landing gear retracted after touching down.Perhaps it was because of the hydraulic pressure that the landing gear was not locked down, or it was simply a structural problem of the landing gear, but now Xu Cang didn't have the heart to find out what the reason was, so he just tried to solve this problem as much as possible. …

"You want to manually lower the landing gear?" Tan Heling froze for a moment.

"Otherwise?" At this time, Xu Cang actually leveled the plane slowly from a steep turn while speaking.

Seeing that Xu Cang was going to level the plane, wouldn't it mean that the plane was about to raise its head and slow down again, and got stuck in the mire of stalling?Although Tan Heling thinks that Xu Cang's sharp turn is only a stopgap measure, but after all, he can hold on for a while, and he can't just rush in the direction of the stall.

In desperation, Tan Heling grabbed the steering wheel, not wanting Xu Cang to level the plane: "Xu Cang, how can you level the plane now?"

When Xu Cang saw that Tan Heling was still interfering with his operation at this time, he immediately became furious: "Damn it, let me go the fuck! Instructor, manually lower the landing gear!"

Tan Heling was scolded by Xu Cang, and she didn't know what to do.Mo Shangyun, who was sitting in the back, reacted quickly, and immediately lifted the cover of the artificial landing gear on the floor. Without further ado, regardless of which landing gear it corresponds to, the handles of the three artificial landing gears were all pulled out one by one.

"If you want to use gravity to lower the landing gear, I feel that you still need a certain amount of maneuvering!" Mo Shangyun could understand Xu Cang's thoughts, but he was not too optimistic.

The reason why Xu Cang wants to level off is because the way of manually lowering the landing gear is to completely use gravity to lower and lock the landing gear.However, Mo Shangyun felt that the problem of the landing gear could not be achieved by relying on gravity.

Sure enough, usually a few seconds after the manual lowering of the gear, if successful, the gear light will come on.In fact, the operation of manually extending the landing gear has nothing to do with the position of the landing gear handle. That is to say, even if the landing gear handle is in the upper position, as long as the manual extending landing gear handle is pulled down, the landing gear can still be lowered.

However, the landing gear handle is still down at this time.According to logic, as long as the left main landing gear is down and locked, it is consistent with the position of the landing gear handle, and the corresponding red indicator light will go out accordingly.

However, after waiting for a few seconds, the red indicator light of the left landing gear still did not change.

As soon as Xu Cang looked up, there was another set of devices on the top of the rear roof that only showed three green lights to indicate the position of the landing gear.Of those three lights, the green light for the left gear did not come on.

"I..." Xu Cang almost cursed, but he didn't have time to wait any longer.The risk of leveling the plane at this point was too great.

However, Xu Cang apparently still did not give up the idea of ​​lowering and locking the landing gear.In any case, the landing gear problem presented too many obstacles to the landing process, and if there was any possibility, he still hoped to remove it.

However, now Xu Cang can't keep leveling, and if this continues, it will be a dead end.At this moment, Xu Cang filled the left disc again, and the plane started to make a steep turn to the left again.However, when the plane's slope had just formed, Xu Cang didn't wait for a moment, and directly pressed the steering wheel to the full right.

In this way, the plane is like an autumn leaf swaying left and right, and the swing is very large. If the seat belt is not fastened, the swing alone is enough to throw people out. …

"He wants to use centrifugal force to throw the landing gear out?" Tan Heling who was beside him immediately realized the intention of Xu Cang's approach, and was extremely amazed in his heart that Xu Cang's methods were so many that it was unbelievable.

However, after several attempts back and forth, the red indicator light on the left landing gear was so stubborn that Xu Cang gave up the last hope to turn it off.

So, Xu Cang let go of the thrust handle with his right hand, grabbed the flap handle without looking at it, and put it directly on the bottom [-] of the flap.

"Xu Cang, manual recovery requires fifteen landings with flaps. No, you want forty landings with flaps and part of the landing gear retracted?" Tan Heling screamed: "Xu Cang, now we can't get off at all, how will the plane land? ?”

Flaps [-] is the landing configuration recommended in the "landing partially or fully retracted landing" inspection, the purpose is to reduce the touchdown speed of the aircraft as much as possible.

In fact, there is a requirement for circling fuel consumption in the checklist, but the Boeing 737 does not have the function of releasing fuel in the air. If it only consumes fuel by circling, the efficiency is too low, and it will take several hours at least.

With such a length of time and the current degree of damage to the structure of the aircraft, this 1566 simply cannot support the required fuel balance conditions.

Therefore, Xu Cang directly skipped the steps of circling and consuming fuel, and directly started to set the flaps to the ground.

The problem now, however, is that the plane's pitch attitude is stuck at such an exaggerated point that it barely restrains its upward motion, even in steep turns.Needless to say landing, it is impossible to just turn the plane into a descent.

Before solving the possibility of descent and landing, Xu Cang started to progress to the steps of landing configuration. How could Tan Heling understand?
In fact, Mo Shangyun who was sitting in the back didn't know what posture Xu Cang would use to complete the landing, but compared to Tan Heling who couldn't see the situation clearly, Mo Shangyun had a very good quality, that is, he knew how to trust Xu Cang, Trust Xu Cang unconditionally.

"Xu Cang, are you going to start the second approach?" Mo Shangyun just asked this question, without a series of questions about how to descend, how to land, and whether you are ready.He just wanted to know if he had made a decision.

"Yes!" Xu Cang said in a deep voice. At this time, the plane has turned from turning right to turning left: "The plane turning left is the beginning of the approach. So, put the flaps down for me!"

If the fuselage of the plane is not damaged, if only the landing gear is not put down, Xu Cang may have more methods to try, such as making a solid landing, and then going around, knocking out the left landing gear.For example, turn at a higher speed and smaller radius to obtain greater centrifugal force.

However, no matter which method is used, it will cause a huge load on the aircraft fuselage structure, and now the last thing that cannot be imposed on the damaged fuselage is excessive load.

The current plane is the porcelain that is about to shatter, and there is no chance to play with it carefully.What Xu Cang has to do now is to gently place the collapsed porcelain on the ground.

"Okay!" Xu Cang replied, Mo Shangyun didn't hesitate anymore, he unbuckled his seat belt directly, got up and pressed the position switch of the spare flap, and kept pressing it. …

At this time, Xu Cang began to gradually reduce the accelerator to slow down the plane.Since the aircraft has a very large attitude and is in the process of turning, as long as the throttle is slightly reduced, the speed of the aircraft will drop rapidly.

However, the speed of the plane was already approaching a stall, so Xu Cang only slightly reduced the accelerator, and quickly increased it again.In fact, Xu Cang's deceleration method is problematic.

Generally speaking, the deceleration plan for flaps must be gradually reduced as the flaps are extended.For example, when the flaps are placed at five, the minimum maneuvering speed of the aircraft cannot be lower than the five flaps, otherwise, this will be a warning, which may cause safety problems, and it will also limit the turning slope of the aircraft in the control, because in When it is less than the maneuvering speed, the maneuverability of the aircraft is limited.

However, Xu Cang directly slowed down to a speed even lower than the flap forty.That is, Xu Cang's deceleration plan was much faster than the flap release progress, and during this process, Xu Cang did not abide by the [-]-degree slope limit.

Therefore, strictly speaking, Xu Cang's method of operation is problematic.Sitting behind, Mo Shangyun could see more clearly, but he didn't say anything, but chose to trust Xu Cang completely.

However, even so, Mo Shangyun still mentioned a little: "Xu Cang, is the speed too slow?"

Xu Cang didn't want to go through the repeated process of speed increasing and then decreasing again, Mo Shangyun could understand this.However, Xu Cang can completely keep the accelerator, just keep the speed.After all, the initial speed is already close to the approach speed with flaps forty.

However, Xu Cang still lowered the accelerator to reduce the speed a bit, thus approaching the stall speed at the top of the red and black speed belt.This speed is obviously lower than the approach speed with flaps [-], which is very abnormal.

However, Xu Cang just said lightly: "It's okay, I know it in my heart."

Hearing what Xu Cang said, Mo Shangyun was also interested and did not continue this topic.

Due to the slow speed of the backup flaps, Xu Cang made another announcement to the passengers while waiting for the flaps to be lowered: "The plane is about to perform a very large maneuver. Please make sure that the seat belt is fastened, and at the same time hold on to the armrest of the seat."

Mo Shangyun, who was still pressing the spare flap position switch with one hand, raised his eyebrows. He moved his eyes away from the flap indicator and looked at Xu Cang with a serious face. He suddenly said: "Xu Cang Cang, now that the aircraft is structurally damaged, can we do that maneuver?"

"So, we only have one chance to try!" Xu Cang's expression froze, and he continued: "Instructor, after the flaps are lowered, P6 board 3: D18 landing gear sound warning trip switch, P6 board 2: B9 flight controls automatically decelerate The board trip switch was all off for me."

One of these two trip switches is used to prevent the audible landing gear warning when the landing flaps are set.Since the left gear is not down and locked, once the flaps are [-], the audible gear warning will sound.

This warning was originally intended to prevent the pilot from forgetting to put down the landing gear, but when the landing gear part cannot be put out, this audible warning will disturb the pilot instead, so it needs to be suppressed.

Another trip switch for the automatic speedbrake is to prevent the ground spoiler from being accidentally raised when landing. …

Landing with some or all of the gear retracted is not the same process as a normal landing.The speedbrakes can only be used when the landing distance is limited and there is no alternative, otherwise the speedbrakes are not allowed to be used during the taxiing process of landing with part or all of the landing gear retracted.Moreover, even if the speedbrake is to be used, the speedbrake must be pulled up after the wing or the engine pod comes into contact with the ground.

The use of reverse thrust is also in principle with the use of speed brakes.

However, in some cases, even if the airbrake is not manually pulled up, the flight spoiler will not be angry, but the ground spoiler will be raised by the dual action of the air logic switch and the idle of the thrust handle, which will destroy In this case, the aircraft needs to be prevented from landing and rolling.

These contents are all in the checklist, Mo Shangyun has no doubts about it, what he is worried about is another thing, that is the way Xu Cang descended.

"What are you talking about?" In the cockpit, only Tan Heling didn't understand, so: "Xu Cang, what maneuver are you going to do?"

However, Xu Cang did not answer Tan Heling, but glanced at the flap indicator, and found that the flaps had been placed after forty, and pointed to the P6 board: "Pull the switch!"

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

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

After hearing the sound of two trip switches being pulled out, Xu Cang took a deep breath, turned his head to look at Tan Heling, and said solemnly: "I think you should also buckle the shoulder straps."

"What did you say?" Tan Heling's face was full of fear, and the deep anxiety had already hit his heart, and it was rapidly expanding, as if he had returned to the moment when the plane was pitching too high and was about to stall and crash.He didn't know what Xu Cang was going to do, but reason told him that it was best to follow Xu Cang's words, so he began to fasten his shoulder straps in a hurry, and his mouth was even more anxious and angry: "Xu Cang, what on earth do you want to do?" ?”

This time, Xu Cang did not ignore his question, but in the process of turning left, he lowered his head and looked down the side window to see the Jianchuan Airport which was located almost directly below.

"It is true that the steep turn can only level the plane, but it cannot complete the descent." Xu Cang withdrew his gaze, and the meaning of determination was clear: "If the descent cannot be completed, it means that the slope is not enough."

Tan Heling's face froze for a moment, and then shouted: "It's almost over [-] degrees, isn't the slope not enough?"

No matter from which angle, a slope of [-] degrees is definitely a big slope, but Xu Cang said it was not enough.

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

At this time, the slope of the plane had exceeded [-] degrees, and the BANK ANGLE alarm sounded in the cockpit.However, the voice fell in Tan Heling's ears like the whisper of death urging him to death.

At this moment, he finally knew what Xu Cang was going to do.An indescribable horror enveloped Tan Heling, he looked at Xu Cang in disbelief: "Are you going to fly upside down?"...

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

"You lunatic, a large airliner can't withstand the aerodynamic load of an inverted flight, and the Boeing manual does not recommend maneuvering an inverted flight." Tan Heling roared: "Also, the fuselage structure of our aircraft is already damaged, so you can Aren't you afraid of disintegrating in the air?"

Before that, Mo Shangyun had already thought of the possibility that Xu Cang wanted to fly the 737 upside down, so when Tan Heling reacted and punctured Xu Cang's idea, he was not very surprised.

It's just that Mo Shangyun's complexion is not very good. Obviously, from his personal point of view, he doesn't really agree with Xu Cang's actions.

It's too dangerous, it's really too dangerous, it's no different from seeking your own death!It's just that out of his trust in Xu Cang, and because he doesn't have a relatively practical method, he can only choose to acquiesce.

"Do you know why I survived so many special situations?"

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

Xu Cang's gaze was like a rock that has not moved for thousands of years, and he softly uttered a sentence: "Because I live to die!"

At this moment, there is a small pickup truck parked on the working path next to the runway of Jianchuan Airport, which is a field service vehicle.According to the requirements of the airport, after the plane landed and was towed away by a trailer, they had already entered the runway and began to check.

However, the plane did not stop after landing not long ago, but pulled up once, which allowed the field service vehicle to continue to park on the working trail.

"The plane just landed, is it necessary to conduct a special runway inspection?" one of the thin ground staff sitting on the right seat complained.

The colleague sitting on the left who looks relatively round doesn't have any complaints: "You can do whatever you are asked to do. How can there be so many complaints?"

"You're enlightened, model worker! I'm off work now, pull me here temporarily." The thin field staff was still complaining endlessly.Suddenly, he noticed that his colleague seemed to be looking at the sky all the time, and followed suit: "Is the plane about to land?"

"It's upside down." The chubby colleague seemed to have seen something extremely terrifying, and the muscles on his face froze.

"It's upside down, what's upside down?" The thin field attendant squinted his eyes and searched the sky. Even though the sun was setting, it was still difficult to look up to the sky against the light.

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

Seeing his colleague's actions, the thin field staff also got out of the car in confusion. He raised his head, followed the guidance of his colleague and found the trace of the plane in the sky.

However, this plane is a bit strange.Because the distance is too far, it is actually more difficult to tell what kind of state the aircraft is in.However, the aircraft's landing gear and vertical tail are too conspicuous.

The landing gear of the plane in the field of vision turned out to be pointing upwards, while the vertical tail was pointing downwards, it was really the other way around. …

"Flying backwards, flying backwards, how can this plane fly backwards?" The field staff yelled, as if seeing something extremely shocking, he grabbed the fat colleague next to him: "I didn't You read it wrong, I read it right, this plane is flying backwards."

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

"This, this... this." The thin and tall field staff was almost aphasic, feeling that he could not describe his heart with words, so he just raised his head and followed the trajectory of the plane.

The plane was going from his right side to the left side. He was so shocked that he forgot to turn around and let his eyes follow the plane. He just kept tilting his head back until it reached the limit. Then fell down.

Fortunately, the fat colleague supported him quickly, so that he didn't fall over and get hurt.

Although he was supported by his fat colleague, he actually sat down on the ground.At this moment, as the altitude of the plane decreases, more details can be seen, and the volume of the plane is getting bigger and bigger in his eyes, and the shock it can bring is even more indescribable.

"I can still fly like this, I can still fly like this." The field staff sat on the ground and repeated these words, feeling as if they were in a daze.

The fat colleague knew that the field staff named Xu Mingjian in front of him had a dream of flying into the sky, and he had also participated in the recruitment, but was finally rejected, so he took the next best thing and worked as a field staff at Jianchuan Airport.

Although it was fruitless to participate in the recruitment, Xu Mingjian still actively inquired about the recruitment news of an airline company during his field work.However, after several years, there is still no progress.

However, his love for flying gave him some understanding of flying itself.But it is precisely because of this understanding that Xu Mingjian understands how terrifying it is to fly a 737 upside down. This is simply beyond common sense.

The fat colleague patted Xu Mingjian on the shoulder. Suddenly, something flickered in his eyes.Subconsciously, the fat colleague intuitively looked in the direction of the flashing light.

Suddenly, his eyes searched the runway for a moment, and found a piece of metal in the touchdown area.It was the shard of metal reflecting sunlight that hit his eyes.

"Old Xu, get up and have a look, is there a piece of metal on the touchdown area?"

Xu Mingjian was pulled up by his colleagues, and he followed the instructions of his colleagues to look at the touchdown area of ​​the runway while he was still in a state of shock.

Because someone pointed out the direction, Xu Mingjian quickly discovered where the metal fragment was, and his expression immediately became serious.However, just as he was about to answer his colleague, Xu Mingjian continued to scan the runway, and the expression on his face froze even more.

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

The fat colleague was startled, and then moved his eyes back along the runway, his face also became terrified.On the runway in front of the touchdown area, there are still more aircraft debris, and the number is so large that it cannot be removed for a while.

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

In the control room of the tower, Director Liu also witnessed the frightening scene of Xu Cang flying the plane upside down, and he saw the details more clearly with the help of a telescope.

Beside him, the assistant was like a sculpture, and said in a daze: "Director, can the plane really fly like this? Did the crew fly like this on purpose?"

"Otherwise? Under normal circumstances, the plane would not enter this state at all." Director Liu put down the binoculars, his heart pounding.The shock Xu Cang gave him was really indescribable. The behavior of this young man who is less than 30 years old is so different from 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 normal attitude.

It is precisely based on this characteristic that it is difficult for the aircraft to spontaneously enter the complex state of inverted flight, and such effects can only be achieved through deliberate manipulation by humans.

The assistant also figured this out, but he had a question: "Why did the crew fly like this? I remember that almost all large passenger planes are now expressly forbidden to fly backwards, right? Now the mainstream large passenger planes in the world are designing I didn’t consider the need to fly backwards.”

Although the design concept of a commercial airliner pursues safety, it naturally also needs to take into account economy, and even in many cases, economy is the first element.

Because in fact, the structural strength of commercial airliners is different. For example, the strength of the leading edge of the wing is much stronger than that of the trailing edge, because in the most common bird strikes, it is usually only the leading edge of the wing. It is enough to strengthen the leading edge of the wing, and the unnecessary high strength of the trailing edge of the wing can save a lot of cost.

Therefore, airliner manufacturers will naturally not strengthen the fuselage of the aircraft to the level of a super-maneuverable fighter under the assumption that large airliners will not fly upside down.

If there is no demand, there is no need for assembly, and the cost is reduced as much as possible. This is the concept of commercial airliners.

Of course, commercial airliners are not just paper.Regardless of design or procedure, Boeing does not want pilots to fly upside down, but that doesn't mean it won't work, at least it may be feasible in a short period of time.

"Xu Cang is not a reckless man who is desperate. He has his reasons for doing so."

The assistant's eyes narrowed slightly: "What if he really has reached the point where he is desperate?"

"What did you say?" Director Liu snorted coldly, his expression very ugly.In fact, since the plane went around just now, he has been feeling anxious in his heart.

In the case of the 747S2 switch, Director Liu has been able to deeply understand Xu Cang's shocking manipulation technology.In the previous communication, Xu Cang also said that the problem is not big, so it is really not a big problem after all.

But the plane went around, and it was so exaggerated that even he, a half layman, could feel the problem and completed 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 to be desperate?

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

Once the airport emergency committee is notified, the matter will become a big mess.Even though the airport emergency committee was contacted and the airport entered a state of emergency, it didn't have a great impact on him.But in the end, it is his duty as the supervisor on duty to minimize the scope of the incident as much as possible. No matter what the situation is, the airport must be put into an emergency state, so the supervisor on duty is too easy to do. …

"Wait a while." Director Liu ordered, but he added at the end: "Let the fire department and the medical team take their positions, but don't move out, wait for our orders."

This is the limit Director Liu can do.Whenever firefighting and medical treatment are dispatched, the sirens are loud, and the scope of influence is too large.

"it is good!"

Although there were some differences in thinking, the assistant followed what Director Liu said and gave up the idea of ​​contacting the airport emergency committee.

At this moment, another staff member walked quickly to the assistant and whispered a few words in his ear, and the assistant's face changed suddenly in a short time.

"Really?" the assistant exclaimed.

"It was reported by the field management department just now, and it was visually observed by the field personnel on standby. It is undoubtedly confirmed." The staff member nodded.

"Damn it!" The assistant cursed, left the staff behind, and walked quickly to Director Liu, and said in a low voice: "Director, the ground staff saw a large number of aircraft parts fragments on the runway just now."

"Huh? The fragments of the plane, where did they come from?" Director Liu just said this, but he immediately understood, and his expression turned pale: "It fell from the 9951N plane!?"

It was the go-around after the touchdown just now that the 9951N aircraft dropped so many debris, which shows that the structural state of the aircraft at this moment is definitely more terrible than the worst result they could imagine.

Perhaps, he began to understand Xu Cang's idea of ​​flying the 737 upside down.

"Is it really time to be desperate?" At this moment, Director Liu also understood the seriousness of the matter.Such a huge amount of aircraft debris is scattered on the runway surface, and it cannot be removed in a short time.

However, according to Director Liu's vision, it seems that the condition of the 9951N aircraft will not last enough time for the airport to clear the runway.Isn't this a dead end again?
No matter what, Director Liu is going to change the order: "Notify the airport emergency committee, Jianchuan Airport has entered a state of emergency. At the same time, notify the field management department to clear the dangerous objects on the road as quickly as possible."

The assistant immediately said: "Then what about the plane, it looks like they are about to land."

Judging from the current trajectory of the aircraft, it seems that the crew is not willing to perform a complete instrument approach procedure, but completes a visual landing by itself.

At this moment, the plane has turned into a three-sided course. If it is fast enough, the crew will not even go on a four-sided course, but directly insert into the fifth-sided course in a continuous turn.

"What to do, the plane must not land."

"What if they have no choice but to land?"

Just by imagining the plane debris all over the ground, the assistant can think of the status of flight 9951N at the moment.Sometimes, the crew can choose not to fall without the control not to let the plane fall.

At certain moments, the aircraft does not allow the operator's thinking and display space.

"No matter what, let's inform the crew first." Director Liu actually didn't have a good idea, and if he really encountered such a dilemma, let the crew decide.

In fact, since the go-around just now, Director Liu has been thinking about contacting the crew.However, because he was worried about interfering with the crew's emergency control, he never took the initiative to contact him, but passively waited for the crew to contact him. But at this point, Director Liu still chose to contact the crew. …

In the cockpit, when Xu Cang continuously turned the plane to more than [-] degrees, Mo Shangyun's expression was okay. He has flown fighter jets, and it is common to fly backwards, so his psychological acceptance is not bad. relatively high.

But Tan Heling is different, let alone on a real plane, even on a simulator, except for the deliberate complex state training, there will be no upside down in the simulated training.

In his thinking, such things as flying upside down should not happen in normal commercial operations, so that when Xu Cang increased the slope to more than [-] degrees, Tan Heling's heart seemed to be squeezed by a big hand. Hold it tightly, as if you are about to suffocate.

"Xu Cang, Xu Cang, if you think about another way, flying upside down is too risky." At the critical moment, Tan Heling is still unwilling to face the situation of flying the plane upside down, hoping that Xu Cang can find a relatively acceptable solution .

Moreover, it was not out of fear, but because he really felt that the plan of flying backwards was not feasible, and the plane would definitely disintegrate in the air.

However, Xu Cang's hands pressing the steering wheel still showed no signs of returning to normal, and his voice was so indifferent: "There is no other way."

At this time, the plane's slope had exceeded [-] degrees, and it was already showing an inverted state, and the altitude that had been rising or leveling finally lost its last stubbornness and began to turn downwards.

Seeing this, Tan Heling almost collapsed, he shouted almost hysterically: "Xu Cang, you are dragging us to die together!"

Xu Cang's eyes gradually narrowed: "No one will die."

"TMD, the 737 can't fly upside down at all, and you said that no one will die." At this time, Tan Heling's face was flushed, and he didn't know whether it was because of being too emotional, or because the head and feet were hanging upside down, and the blood flowed backward.

However, Xu Cang's face remained unchanged, and he said firmly in his words: "737 can fly upside down!"

However, looking at Xu Cang's appearance, although he seemed to be firm, he actually seemed to be convincing himself.

"Fuck your ass, there is no mention in the manual that the 737 can fly backwards." Tan Heling yelled.

"No! Someone has done this before!" This was Xu Cang's last sentence. After that, Xu Cang didn't say anything.

This time, together with Mo Shangyun, both of them were shocked.Because in their memory, not only in China, but even in the history of foreign civil aviation, there has never been a precedent for flying a 737 upside down.

It is precisely because there is no such precedent that Boeing can abandon the ability of the 737 to fly backwards in the design with such peace of mind.

However, Xu Cang is not a random person, this is a moment of life and death, he will create a precedent?Could it be that they just don't know because of their own knowledge?

Just when Mo Shangyun and Tan Heling were startled, Xu Cang had already controlled the plane to complete the final slope construction, and the plane was in the reversed state.

However, there is one thing that only Xu Cang knows.The memories of Mo Shangyun and Tan Heling are not wrong. So far, there is indeed no precedent in the history of civil aviation in the world, because the case known to Xu Cang happened 737 years later. The absolute genius completed the feat of flying the 20 upside down, proving that this maneuver is feasible, at least within a short period of time. …

Now that the future legend has set an example for him, why doesn't Xu Cang follow the path?
However, the plane was damaged at the tail after all, so Xu Cang said that there was only one chance.Over time, it is hard to guarantee that other problems will occur.

Once the plane turned to fly upside down, the exaggerated upward attitude turned into a downward pitch, and the plane began to descend at an extremely large descent rate.

Because the attitude of the downshoot is too big, even when the throttle is closed, the speed of the aircraft is still going up.At this moment, Mo Shangyun's eyelids twitched, and he immediately remembered that not long ago he was still questioning why Xu Cang adjusted the approach speed to a speed obviously lower than the flap forty.Now he finally understood Xu Cang's intentions.

In the super pitch attitude, the idle thrust cannot prevent the speed increase.Flying the aircraft upside down already places a huge burden on the fuselage structure, as does the fragile flap structure.

Therefore, Xu Cang cannot allow additional loads to be applied to the flaps, which is the so-called overloading at overspeed.

If the impact of overspeed is superimposed on the already overwhelmed flaps, then maybe the flap structure will be the first to fail and crack.Therefore, before turning into inverted flight, Xu Cang must allow a certain amount of space for the speed increase, even if the speed is reduced to the point of stalling.

"He knows it all!" At this moment, Mo Shangyun couldn't help admiring Xu Cang's predictive ability, he seemed to be able to think of everything in the future, and the seemingly unclear future was like a stop-motion animation in Xu Cang , he is ready for everything.

However, Mo Shangyun still doesn't know who Xu Cang is, and his amazement is far from over!

When the plane barely crossed the end of the runway, Xu Cang hardly waited and started to turn to the fifth side of the runway, but in the case of inverted flight, the controls were mirrored.

Moreover, according to visual inspection, Xu Cang's three sides are kept very close to the runway, and the current wind direction is blowing the plane to the fifth side, so it is very likely that the plane will not be able to take a formal four sides, but in continuous turns Cut into five sides.

Sure enough, Xu Cang's turning slope was very steep, and the plane turned over the fifth side of the runway while falling rapidly.Under such circumstances, Tan Heling only felt that the blood in his whole body was piled up on the top of his head, he only felt that his head was about to explode, his eyes were filled with dense bloodshots, which protruded obviously, as if he was about to fall out of his body in the next moment. Out of the eye sockets.

It was so painful, he hadn't exercised in a long time.When I wanted to learn to fly, I had all kinds of sports equipment at my fingertips in order to cope with the annual physical fitness test, but when it really came to work, I was getting farther and farther away from what I used to be!
However, at this moment, a large amount of blood stagnated into Xu Cang's brain, and he was sober as never before. He knew what he should do, now and in the future!

"Gear Inhibit Switch, Inhibit! Engine Bleed Air Switch.Close!"

When the plane was about to turn to the fifth side, Xu Cang issued an order.

Mo Shangyun could reach out and close the engine bleed switch, but he couldn't reach the near-ground landing gear suppression switch.However, fortunately at this juncture, Tan Heling still played a little bit of his role.Struggling to restrain the landing gear inhibit switch near the ground. …

"Teacher, listen to my password!" Xu Cang said fiercely.

Mo Shangyun hummed, but he suddenly found that there seemed to be some problems with the direction the plane's nose was facing.

"Xu Cang, the runway is on your right, you leveled too early."

Originally, Mo Shangyun didn't want to remind Xu Cang of this kind of thing, because it was the most basic corrective action, a basic technique that even student pilots must master.

However, at this moment, because Xu Cang turned into the third side very early, the length of the fifth side was very, very short, almost turning around and entering the sky above the runway, so that there was very little room for the pilot to correct.

Therefore, in this ultra-short final maneuver, it is best to align the runway at the beginning, otherwise the follow-up will be quite passive.

However, with such basic knowledge, Xu Cang seemed to have made a low-level mistake. He deviated to the left side of the runway extension line, and the deviation was not small. If he did not correct it, he would lose the final opportunity to correct it.

"No, I have no problem!"

At this time, Tan Heling also noticed Xu Cang's deviation, which was so big that any pilot could see it.However, Xu Cang still said that he has no problem.

"You are obviously far behind!" Tan Heling said: "Correct it quickly, or it will be too late."

This plane can no longer support the burden of doing it again, and he, Tan Heling, doesn't want to do it again.

At this moment, the cockpit suddenly remembered Director Liu's voice: "Xu Cang, on the runway, the field staff observed a large number of FOD visually, and they can't land, can't land!"

FOD is a professional term, Fn Object Debris, which refers to foreign substances, debris or objects that can damage aircraft.Of course, what Director Liu was talking about was naturally the plane debris on the runway.

However, what the field department reported was that it was very likely that it was a piece of aircraft debris, because the field personnel had not yet entered the runway for direct visual inspection.Therefore, even if it can be confirmed, Director Liu still uses FOD to describe it professionally.

He felt that with Xu Cang's ability, he should be able to quickly understand what he meant.

But Mo Shangyun was the first to react. He immediately thought of a possibility in his mind, and said tremblingly, "Is it the plane debris from the grounding just now?"

Airport runways are inspected by specialized personnel, and it is impossible for a large amount of FOD to appear suddenly.During this period, only one of their planes took over the ground, and it touched down with a damaged fuselage, so it is reasonable to shake off a lot of debris.

However, before Mo Shangyun could say anything, Xu Cang spoke first: "Teacher, I just said that we only have one chance!"

"However, there are FODs on the runway, and we will die if we fall." By this time, Mo Shangyun could no longer agree with Xu Cang's thoughts, and now he must not be able to land again.

However, Xu Cang didn't seem to want to abort the approach, he just said indifferently: "Who said I'm going to land on the runway?"

Mo Shangyun was taken aback: "What did you say?"

At this moment, on the control tower, Director Liu, who found Xu Cang still approaching through the telescope, was in a hurry, and there was no answer from Xu Cang, so in a hurry, he turned around and picked up the microphone and shouted: "Xu Cang, go around!" , Go around, I command you to go around! The runway can’t land, can’t land, do you hear me!”…

When Director Liu's urgent cry resounded in the cockpit, Mo Shangyun's pupils shrank suddenly, and he felt a chill all over his body. Now he understood Xu Cang's thoughts.

Just now he said that Xu Cang was not aiming at the runway, but Xu Cang said that he had no problem.Xu Cang was right, because he had no intention of landing on the runway.

At this moment, taxiway A came into view directly in front of their field of vision.

He wasn't going to land on the runway, he was going to land on main taxiway A.

From the very beginning Xu Cang knew that the runway would not fall, he knew everything, ahead of everyone else, everything was under his control.

At this time, in the cockpit of Muhua Flight 1233 parked in front of taxiway A, the co-pilot tilted his head hesitantly, looking to the five sides through the side window on his side.

He could already see flight 9951N on the final side with his naked eyes, but after experiencing the initial shock of visually seeing the aircraft flying upside down, the co-pilot discovered a more urgent problem.

He patted the captain on the shoulder: "Brother, do you see that the plane is not flying towards the runway?"

At this moment, the captain was also looking at the plane flying upside down in amazement. After being reminded by the co-pilot, the captain was stunned for a moment. He really didn't notice where the plane was flying.

However, since they were not directly facing flight 9951N, there was a deviation in their line of sight, and it was difficult to be sure for a while.So he quickly hit a final extension of runway 05 on the CDU.

The moment the green dotted line appeared, the captain's face froze.Thanks to the presence of the transponder, they could already see the 9951N's TACS signal on the Navigation DU.And this signal point is not on the five-sided extension line of No. 05, but a little bit to the left.

"Is it a simple roll error?" The captain hesitated for a while, but as the 9951N plane got closer, the captain's face became paler, and the uneasiness in his heart grew wildly, until he could clearly see After seeing the details of the paintwork on the 9951N aircraft, and the aircraft did not have any roll correction actions, he cursed: "What madness is the crew of 9951?"

Therefore, the captain directly pressed the speaking button: "Tower, 9951N aircraft is not on the flight path of No. 05!"

As soon as this remark came out, Director Liu, who had never received Xu Cang's answer and was so anxious, was taken aback. He directly dropped the microphone, picked up the binoculars and observed the position of the 9951N plane again.

After only two seconds, Director Liu's heart seemed to have stopped.Because he clearly saw that Flight 9951N was not heading towards the runway, but the main taxiway A.

However, after receiving the information that made him feel suffocated, Director Liu's eyes moved, and he immediately fell on the plane of Muhua Airlines parked outside taxiway A.

At this moment, the nose of the plane of Muhua Airlines has almost reached taxiway A. If Xu Cang wants to land the plane on the main taxiway, if he is not careful, the wing of the plane will hit the plane of Muhua Airlines. on the head.

After all, even if it is the main taxiway, its width is far less than that of the runway, and there is very little room for the crew to move around during the taxiing process.

In fact, Director Liu still doesn't know about the landing gear problem of the 9951N aircraft.If he knew that the landing gear of the plane was still faulty, it would undoubtedly increase the difficulty of ground control, and he would have to be scared to death. …

However, just as Director Liu was shocked by all kinds of horrible news and his mind went blank, the flight crew of Muhua Airlines waited for a long time for the control to reply.At this moment, he can already see all the details of the 9951N aircraft clearly. Seeing that the aircraft is about to land, it is really facing the taxiway.If the nose of my own plane is too far forward, it is easy to be hit by the wingtip of the high-speed taxiing 9951N flight, and the consequences will be disastrous at that time.

So, the captain didn't care about the tower, and directly roared in the frequency of the tower: "9951N, where the hell are you landing?"

This voice directly woke up Director Liu, whose brain was overloaded. After waking up, Director Liu was covered in cold sweat, turned his head and grabbed the microphone, and shouted at the same time: "Xu Cang, master A cannot land, there is a plane from Muhua Airlines coming out. , after landing, it is easy to scratch the wingtips. Xu Cang, go around, go around quickly!"

"I know, I know, I know everything!" In the cockpit, Xu Cang finally couldn't bear it anymore, and shouted in the tower frequency: "I know everything, then, can you all shut up!"

Yes, he knows everything!He had thought of everything since the plane touched down and went around.He saw the plane of Muhua Airlines parked in front of the taxiway on the left. He expected that the damage to the aircraft would cause debris when it touched down. He knew that the runway could not be landed. .

He knows it all!

So, he also knows what he should do!
His gaze, his vision, and his thinking have always been ahead of everyone.What others saw and what they couldn't see, all presented a picture in his mind, and he found a feasible way out of the information surrounding him!
The moment Xu Cang's voice fell, the plane had passed the last [-] feet.

At this moment, Tan Heling didn't care whether what Xu Cang said was true or not, the plane was in Xu Cang's hands, he could only choose to believe it.

"Xu Cang, it's time to touch the ground, turn back, turn back!" Tan Heling said eagerly.

Xu Cang was unmoved: "Not yet, just wait!"

"How long until?"

Xu Cang stopped talking now, he gradually held his breath, the next moment was the time to decide his fate.The plane cannot turn back too early, otherwise, it will be difficult for the plane to complete the final sinking with a normal attitude.

Therefore, he has to wait, wait for a time when there will be no problems.

It was when the plane passed the last [-] feet that Xu Cang pressed the cockpit to the right, and the plane began to turn back to the normal flight attitude at a clockwise angle.

You must know that the wing length of the 737-800 is nearly 130 feet, that is to say, Xu Cang only has a vertical margin of [-] feet.And in the process of turning back to the center, the plane has to descend, so that at the lowest point, the wingtips of the plane can barely skim the ground.

During the turn, Xu Cang resisted the left rudder and used the force of the reverse rudder to offset the lateral drift caused by the roll of the aileron.The aircraft can always maintain the direction line aligned with the taxiway.

Xu Cang had a very steep slope this time, and it took only an instant to get the plane back on track.The moment the plane returned to normal, the plane had already flown over the runway. …

The radio altimeter's report even skipped the fifty-foot altitude report, and the first one was the value of forty feet.At this moment, Xu Cang slammed the accelerator up, supplying the last bit of energy to the aircraft that was not sinking too much when it returned to the center, and then directly turned off the accelerator.

Since the pitch attitude of the aircraft turns to a positive value and is extremely large, the initial sinking of the aircraft is very small, consuming the speed of the aircraft.But Xu Cang added the throttle at forty feet, so that the speed of the plane did not decrease significantly immediately.

In this way, it was normal for the plane to sink until it reached twenty feet.Once past twenty feet, the aircraft's energy is exhausted, and the speed begins to drop continuously, resulting in less lift.With the decrease of lift force, the attitude becomes larger, and the speed decreases again. Under the vicious circle, the sinking of the aircraft begins to increase gradually.

Fortunately, at the moment when this feedback was formed, the aircraft was already at a very low altitude.It was when Xu Cang fell to five feet that he felt that the sinking became unacceptable.

However, at the moment when this idea came into being, the plane smashed hard onto the road surface.

At the same time as the plane touched down, Xu Cang began to gradually press the plate to the right and stepped on the manual brake at the same time.

"Turn off the fuel pump!" Xu Cang shouted.

Mo Shangyun, who was already prepared, immediately got up slightly and turned off all the fuel pumps.This is what the checklist needs!

Xu Cang's pressure plate is skillful. As the speed of the plane slows down, he gradually increases the amount of pressure plate, so that the plane will always keep a slight tilt to the right.

And due to the existence of the right pressure plate, the crosswind on the ground is extremely small, which makes the aircraft slowly veer to the right even without the action of rudder and differential brakes.

The two pilots in the cockpit of the Muhua Airlines plane parked in front of the taxiway saw the flying 9951N flight, and their hearts almost stopped in fright.

But when approaching the Muhua Aviation aircraft, the right landing gear of the 9951N aircraft was already approaching the edge light on the right side of the taxiway.Keep as far away as possible from the plane of Muhua Airlines.

At the same time, due to the overall tilt of the aircraft to the right, the left wing is raised and the right wing is lowered.The angle of inclination is so large that the tip of the right wing almost touches the tip of the lawn next to the taxiway.

It is precisely because of the sufficient distance and the lifting of the left wing tip at the same time that the left wing tip of the 9951N almost slipped from the nose of the Muhua Aviation aircraft under the shocked eyes of the two pilots of Muhua Aviation. Flying across the sky, there is a slight difference between the two.

As soon as the Muhua Aviation plane passed by, due to the continuous decrease in the speed of the plane, the aerodynamic performance of the wing surface was no longer sufficient to maintain the tilted state of the plane.

Moreover, after centering, the aircraft continued to tilt to the left because the left landing gear was not extended and locked.Finally, at about sixty knots, with a violent vibration, the left wing tip of the aircraft touched the ground first, and then the pod of the number one engine.

The moment the tip of the left wing touched the ground, Xu Cang no longer had any scruples.Pull up the airbrake, and at the same time pull up the thrust reverser of the No. [-] engine.Now that the No. [-] engine pod has touched the ground, the reverse thrust of No. [-] engine must not be activated.Of course, the effect of reversing below [-] knots is already very poor, but it is better than nothing.

The final sixty knots of the aircraft are decelerated in less than five seconds under the action of speedbrakes, brakes and thrust reversers, as well as friction from the wingtips and engine pods.

The moment the plane stopped, the air was filled with a scorching burnt smell.

Xu Cang took a deep breath, pulled out the parking brake, then slumped on the seat, sweating all over his body, and said weakly: "Okay, let's evacuate!"
