Return to 2000: Captain of the Great Powers

The moment Xu Cang held the steering wheel, he encountered the same situation as David before.

Due to the broken right wing, the aircraft was almost out of control in the roll.

The basic operating principles of the airplane have not changed fundamentally since the invention of the Wright Brothers.As we all know, the pilot uses the ailerons to control the roll of the aircraft, but this control method is not unilateral, but is completed by the cooperation of the left and right ailerons.

For example, if the aircraft wants to turn left, when the pilot presses the plate to the left, the aileron on the left wing will move up, causing the left wing to move down, while the aileron on the right wing will move down, causing the right side to move downward. The wings move upwards.

The left wing goes down, and the right wing goes up. With the cooperation of the two, a smooth left roll can be completed.

However, at this time, the right wing breaks, and most of the aileron components on the right wing also disappear, which results in that basically only the left aileron can play a role in the deflection moment.However, due to the difference in lift generated by the wings on both sides, the rolling moment of the left aileron alone cannot offset, so the aircraft began to roll uncontrollably to the right.

After Xu Cang tried several times and still couldn't completely change the state of the plane, he finally gave up this purposeless and meaningless attempt.

At this moment, the plane is not completely uncontrollable, but after the right wing breaks, the state of the whole plane and the reaction after the control input are completely beyond Xu Cang's comprehension.He began to be confused, at a loss, and began to understand why this was an unsolvable situation.

"Xu Cang, what should I do, what should I do?" After realizing that Xu Cang might really be helpless, his emotions almost collapsed.

At this time, the aircraft is maintaining a huge tilt state, and the lift force component formed by the airflow on the left wing is not much.Therefore, on the vertical table, the aircraft always maintains a super large descent rate of 1 feet per minute.At the moment when the large wing broke, the altitude of the plane was only more than 3 feet. If this continues, the plane will crash in less than two or three minutes.

Due to the rapid fall of the plane, the speed of the plane became very high during the energy conversion, and Munich Airport, which was not too far away, was already close at hand.But the airport, which is so close at hand, is like heaven and man separated forever, and it is impossible to touch it.

The height is enough, but the problem is that the plane is no longer controllable. How can we smoothly land the plane that is no longer controllable?
This is the most critical question.

Obviously, no one can give this answer.

Xu Cang did not lie, in this situation, only God can survive.

The aircraft's descent rate fluctuated greatly, falling back to less than [-] feet per minute for a while, and increasing to nearly [-] feet per minute for a while.In such a terrifying descent rate, after the plane quickly approached the ground and broke through the clouds, David could even vaguely see the ground.

"We're dead, we're dead!" David roared frantically, venting his flood-like fear. It was the mighty power of nature, and the unshakable ending was just like the pitiful and unshakable ending they were facing now. Sad reality.

2 minutes, 2 minutes later this plane will turn into a sea of ​​flames, no one can survive.

The goddess of fate has already cast a concerned gaze on them.

Xu Cang tried his best to control his breathing, he forced himself to calm down, his complicated thoughts would only make him lose his last chance of survival in wrong actions.However, facing this almost incomprehensible situation, Xu Cang's heart was also filled with fear. He is also a human being, and he also has human emotions. Just like David who is already waiting for the death sentence, he can no longer calm down. up.

At this moment, Xu Cang's left hand holding the steering wheel began to tremble irregularly. He couldn't control his left hand, and he couldn't even hold the steering wheel.

"Am I really afraid?" Xu Cang thought dejectedly.

Before, he was afraid that he would lose his connection with the plane, and he was afraid that he would no longer be the omnipotent son of the sky.

Now, he is afraid of death, the most primitive and essential terror of human beings.

Fear makes cowardly,
Fear makes people retreat,
Fear makes people confused,
Xu Cang should have been able to think of all this.The unsolvable problem of broken wings cannot be solved at his peak moment. This is a fatal situation.Just now, he took over the control of the plane again, thinking about changing his own destiny under the instinct of survival, however, everything was nothing more than a fly shaking a tree.

That uncontrolled left hand is the most authentic portrayal of Xu Cang.

He was human too, a humble mortal.

After all, he was swallowed by his own demons.

Maybe it's because he sensed Xu Cang's emotions, or maybe it's not a situation that needs to be felt carefully to understand.In that passenger cabin, the sharply tilted fuselage and the frantically falling fuselage like a fallen star already showed the problems they faced.

A lot of sundries were scattered in the cabin, and water stains from drinks were everywhere, all of which were the consequences of the tilting of the fuselage.

The passengers in the cabin were obedient, and they all fastened their seat belts, so when the wing broke and the fuselage tilted suddenly, no passenger was thrown out.However, due to the leaning of the fuselage, almost all of them were in a situation with their feet in the air, especially the passengers in the window row on the left.

They are frightened and confused, like rotten and ignorant livestock waiting for the butcher's knife of death.

They didn't roar or go crazy. At the beginning of the tilt of the fuselage, they had already shed all their strength and made the hottest cry for help, but there was no so-called response. The ruthless and cold reality drowned out that unrealistic hope. fantasy.

Many people can only let out a long and weak cry in their hoarse throats. Matching their posture in the air, they are like dying people who are hung from a dead tree and their necks are tightened by a noose.

Captain David is lucky, because he has not yet become numb, and has not lost his survival instinct under the scythe of death.

However, the breath of fear emanating from his whole body is the most greedy delicacy of the death behemoth.

The end is so close, so close that it feels as cold as midnight.

Captain David no longer knew how to change his destiny at this moment. In the frightened and at a loss, he could only pick up the belief that did not match his profession, and called softly: "Jesus!" ·Christ."

Following the prayer of the captain David, the plane broke through all the clouds under the unstoppable fall, and the dim and warm sunlight shone on Xu Cang's face, seeming to blow away the dust and haze in Xu Cang's heart in an instant.

The vast land came into view, and he saw everything clearly, where his fear came from!
He was never afraid of death.

He faced death, he lived through death, he overcame death, so he can be here now, he has a second life.

Death is never the greatest fear, loss is!
Only when you own it can you experience the pain of loss.Xu Cang lost once, and now he is lucky to experience the feeling of possession again, how can he repeat the pain of loss again?
He has infinite nostalgia for this beautiful world.Losing her was Xu Cang's greatest fear.

The sun at dusk is so kind, it is the last tenderness that the sun gives to the world before day and night alternate.It will engrave this gentleness in the hearts of the world, and let them remember that as long as they survive the cold night, warmth will come.

This is hope!
As long as there is hope!

The sun caressed Xu Cang's pale face gently and softly.At this moment, half of the sun has disappeared below the horizon, and the night is coming, just like Xu Cang's fate at this moment.

But at this moment, the tenderness that pierced his heart seemed to awaken the deepest memory in Xu Cang's heart, the sadness when he sank into the endless sea in Tokyo Bay.

At that time, he made his own choice, and greeted his death sadly and pitifully, until a pair of warm and gentle arms hugged him tightly, until the hot and loving breath entered his mouth, until He saw her face clearly.
Until this moment, he understood everything!
The endless nostalgia for the world should never be a rope that binds hands and feet, but should be the sun at dusk, before the deep night arrives, shining the light of hope in the bottom of my heart and keeping it.

"I can't die here, I shouldn't die here!"

Hope is an interesting thing, it can also make people lose their thinking and reason, but compared with the stagnation caused by despair, hope will burst out the most brilliant light and courage in the world at this moment.

Courage is the pioneer of survival.

Xu Cang no longer wavered, no longer confused, he realized something, so he was extremely firm.

His heart constricted violently, pumping blood to his extremities.The hands and feet that had been numb from fear and despair regained their mobility.He is no longer afraid of the inner demon, because that no longer exists.

After all, everything returned to the proper track. With Xu Cang's breathing, he could feel everything about the plane, and the incomparable sense of harmony returned.

No, it's not that he's back, but he has reached an unprecedented height. Xu Cang knows that he has ushered in his prime!
His thoughts, his perceptions enveloped the fuselage.He doesn't need to look at the instruments, he doesn't need to look at the outside world, he doesn't need to refer to any other external objects, but he can know everything about the aircraft.

In the extremely complicated state at this moment, Xu Cang seemed to have seen that little hidden rule, which was their way of survival.

Suddenly, Xu Cang finally moved!
He did not steer the plane aimlessly, but lightly stepped on the left rudder, which had been returned to normal before.Compared with the various previous attempts, the control input this time is so simple, but just like this, the plane that was falling like a falling rock suddenly froze for a moment, and the rate of descent suddenly changed from more than 4000 feet per minute. Down to almost two thousand feet per minute.

Sitting in the cabin, the girl who had talked with Xu Cang before realized the change of the plane for the first time, and then the captain Schneider behind the cockpit also vaguely felt a change in his heart.

"Stopped!?" He immediately turned his attention to the aircraft's elevator gauge, and the descent rate of [-] feet per minute appeared before his eyes.

"No, no, no, this." Schneider almost held his breath. Since the wing broke, the aircraft's descent rate has never been so small. This is not the result of a natural fall, but human intervention.

Suddenly, he fixed his eyes on the tenacious and resolute figure on the left.

"he made it?"

As the initiator of everything, Xu Cang was the one who first noticed the change of the plane.

Step on the left rudder, but the aircraft reduces the descent rate?
It wasn't supposed to be something that could be related, yet it happened.

Xu Cang's expression didn't change at all, he stepped on the left rudder again, at this moment, the descent rate of the plane slowly dropped to more than 500 feet per minute.

At this moment, even Captain David noticed that the state of the plane had changed and it was no longer an uncontrolled situation.

"Xu Cang, you." Captain David didn't know what Xu Cang did, but under such a large tilt and the lack of lift of the aircraft, the aircraft was able to maintain the descent rate at more than 500 feet per minute , which is clearly not a normal behavior.

Xu Cang is manipulating the plane! ?

The captain Schneider behind him could see clearly what Xu Cang was doing.

"Put on the left rudder?" Captain Schneider couldn't understand the relationship between the input of the left rudder and the decrease of the descent rate, but all this happened in front of his eyes. He couldn't understand Xu Cang's operation, couldn't understand Xu Cang Cang's state, but he can understand that everything is no longer a foregone conclusion.

Life is here!

As long as the plane could be steered, even in ways he couldn't understand, it worked.

Schneider's mouth opened, he didn't dare to speak, he didn't dare to disturb Xu Cang, he was afraid of losing this hard-won hope, like a flower in a mirror and a moon in water.

At this time, Xu Cang pushed down slightly.

Ejector, nose down, this is the most basic knowledge in the flying world.

However, in response to this plane, the plane unexpectedly turned to the right from the original sharp tilt, and began to slowly turn around.

That's right, the roll that couldn't be turned back no matter how hard you tried, unexpectedly loosened at this moment.

Then, Xu Cang cooperated with the movement of the ejector rod, pressed the plate to the left, and the wing of the plane rolled to the left again. In the end, it was able to maintain a tilt angle of almost [-] degrees, maintaining a roughly level flight posture for a period of time.After that, after about four or five seconds, the aircraft's bank angle increased again, returning to a bank angle close to fifty degrees.

However, this is completely enough, which means that the aircraft has a slight possibility of landing.

On the right side, the captain David almost screamed, it was like Jesus Christ had descended on Xu Cang.Compared with the previous inclination angle of more than [-] degrees, the inclination angle of about [-] degrees can barely become a landing posture at this moment.

Xu Cang really did it!He really had control of the plane.

"How could it be like this? How did he do it?" Captain David roared in his heart. Facing such an inhuman operation, he already worshiped Xu Cang as a god.

However, in the remaining rationality, David seemed to understand Xu Cang's thoughts.

Due to the huge lift difference between the two wings, the aileron on the left wing alone cannot suppress the tilt of the aircraft fuselage.Therefore, when the wing breaks, the fuselage tilt is inevitable, which is the only way to maintain flight.However, with such a large tilt angle, the aircraft will definitely not be able to land, so before landing, the aircraft fuselage must be aligned, at least to a relatively acceptable angle.

Previously, the aircraft could not be maneuvered at all due to the excessive tilt of the fuselage.It can only fall at an extremely fast speed in the absence of lift, and that is an unsolvable situation.

However, Xu Cang seems to have found a ray of hope in this fatal situation, that is, the functional exchange between the elevator and the vertical tail.

In fact, after the wing of the plane breaks, it has lift itself, and after a large amount of fuel has been discharged before, the total weight of the plane is unusually small, even in the case of a single engine, even at a huge tilt angle, the left The side wings can still generate relatively sufficient lift.

This lift may be decomposed to the point that the aircraft cannot climb or even level off, but it is absolutely possible to maintain a controllable descent rate. The only problem is that there is no rudder surface to control the pitch of the aircraft.

On an aircraft with normal biplanes, if there is no elevator to control the pitch of the aircraft, even if the wings on both sides can generate enough lift, the aircraft still has the possibility of descending.Therefore, how to find a way to control the pitch of the aircraft when the fuselage is tilted significantly is the only way to survive.

Obviously, pilots at the level of David or Schneider can understand most of the flight controls, but this alone is not enough to cope with the current situation, so this is the gap between Xu Cang and ordinary pilots.

During this period, the state of the aircraft is extremely complicated, which is beyond the comprehension of the human brain.

However, Xu Cang was able to perform anti-human operations in a way beyond human cognition after he was sober.

When the fuselage is tilted sharply, the functions of the elevator that originally controlled the plane's pitch and the rudder that originally controlled the plane's yaw have undergone a fundamental change. In other words, Xu Cang actually used the rudder to control the plane's pitch just now, but The elevator controls the yaw of the aircraft.

The yaw of the aircraft is not exactly equivalent to the effect on the roll.However, the two can assist each other at a certain moment. For example, when the aileron is stuck, in addition to using the differential throttle, the pilot usually uses the rudder to perform auxiliary roll operations.

Xu Cang was on the ejector bar before, and the elevator pitched down, and the aircraft would produce a yaw moment to the left. At the same time, he pressed the plate to the left to form a roll moment to the left. The unstoppable rightward roll moment generated by the difference in lift.

This is true from a theoretical analysis, but this extremely anti-human and extremely complicated manipulation method is simply difficult for humans to control.Xu Cang must first break the inherent concept of traditional manipulation methods and form a new corresponding relationship, and the theory is completely different from the reality.

Reacting to the control, no one can know what Xu Cang's so-called effect of controlling the aircraft's pitch by using the rudder is.Because the shape and area of ​​the vertical tail are completely different from those of the horizontal tail, the rudder effect produced by it is also different, so Xu Cang didn't know what the pitch attitude of the plane would be if he stepped on it. It makes it impossible to precisely control the aircraft, and it can only depend on the pilot's feeling.

And human feeling is a very mysterious state, it may be very precise, and it may also be thousands of miles away.

Intellectually speaking, the possibility of the latter is far greater than the former.

Unfortunately, landing an aircraft is undoubtedly an operation that requires extremely high precision.

However, compared to the previous almost desperate situation, it is much better now.

As the plane descended in a nearly controllable manner, David had vaguely seen the runway in Munich. At this moment, a sliver of hope ignited in his heart.

Could it be that he could really survive?
He touched his chin, hesitated for a long time, and asked, "Can I fall down?"

Xu Cang pursed his lips, and replied in an almost mechanical tone: "No!"

"why?"

Xu Cang frowned: "The runway is too short!"

"If you land at the current flight speed, the runway in Munich is not enough, not enough at all!"

"Landing at the current flight speed?" David looked at the airspeed indicator: "Why did you land at the current flight speed, which is nearly twice the approach speed in the normal configuration."

That's right, the current speed is so high that it can't even release the flaps.But according to Xu Cang's intention, it is impossible to complete the landing at this speed.

"This speed is too high, it's impossible to land, Xu Cang!" Captain Schneider shouted: "Twice the approach speed, the 600-meter runway at Munich Airport is not enough."

Munich Airport has two runways, and now they want to approach the longer runway 17/35.Before the expansion, the runway was 3000 meters long. For most aircraft, this runway length is completely sufficient, but for the Boeing 777, the runway of 3000 meters is slightly shorter in some special cases. Obviously stretched.

Therefore, before the expansion, Munich Airport did not receive Boeing 777 aircraft.

However, the runway was extended by 400 meters during the extension project.A runway of 600 meters can basically handle the Boeing 777.However, this does not mean that all situations can be solved. For example, now Xu Cang wants to land at nearly twice the normal approach speed.

It is clear that there is a strong positive correlation between landing stop distance and approach speed.Captain Schneider didn't even need to look up the landing distance table to conclude that the 600-meter runway was simply not enough.

No way, this speed is too great, too big to imagine.

"Why do you approach at such a high speed?" David couldn't understand Xu Cang's behavior. It's not that he couldn't stop the accelerator, and it wasn't that he couldn't slow down. Why did he approach at such a high speed? Isn't this just asking for trouble for himself?

"No!" Xu Cang just said indifferently.

"Why?" Obviously hope was right in front of him, but Xu Cang's stubbornness made David feel a little anxious.

"Why?" Xu Cang snorted: "The rudder effect."

After finishing speaking, Xu Cang stepped on the accelerator and stepped on the left rudder at the same time. In this way, the descent rate of the plane was stopped, but the speed began to drop rapidly.

Originally, Xu Cang kept pressing the left disc, and at the same time pushed the bar slightly to eliminate the rolling moment to the right.

In this way, although the inclination angle of the large wing of the fuselage cannot always be controlled at [-] degrees, it is still much better than the previous inclination angle of more than [-] degrees.Besides, for the sake of control stability and actual flight performance, it is impossible for Xu Cang to keep the plane at a small bank angle all the time, and now a bank angle of almost [-] degrees is more appropriate.

However, at the moment the speed decreased, the aircraft, which had a slightly stable bank angle, immediately rolled to the right, and the rolling moment suppressed by the left aileron and horizontal tail immediately became uncontrollable.Almost before David could react, the plane's bank angle exceeded seventy degrees.

Under such a huge tilt angle, the lift force of the left wing is further decomposed, so that the rate of descent begins to increase again.

Moreover, because of the single engine, the aircraft naturally has sideslips.But Xu Cang could only tolerate the existence of this kind of sideslip in order to use the rudder to control the pitch of the plane.When the plane was turning sharply to the right and there was a side slip, it almost went straight to the right and fell downside down, entering an extremely dangerous low-altitude spin state.

Xu Cang's practical operation scared David to death.

Fortunately, Xu Cang's repair operation was very quick. He stepped on the accelerator, and then input more left rudder to increase the speed. In this way, the plane returned to a stable state.

"Speed, rudder effect!" Captain Schneider's expression became extremely gloomy again.

He began to understand what Xu Cang meant!

It is well known that the rudder surface effect has a direct positive correlation with the airflow velocity flowing over the airfoil.The faster the airflow speed, the stronger the rudder surface effect, which is relatively easy to understand.

The airflow speed is also directly related to the aircraft speed. As long as the aircraft decelerates, the airflow speed flowing through the wing surface will also decrease, which will cause the corresponding rudder surface effect to decrease.

The key to the fragile stability Xu Cang maintained just now is that Xu Cang increased the yaw moment generated by the horizontal tail to assist the roll moment of the left aileron, so as to suppress the roll moment caused by the lift difference.

However, as the speed decreases and the rudder effect decreases, the yaw moment produced by the horizontal tail will decrease at an extremely exaggerated speed, so that it cannot assist the roll moment of the left aileron.As a result, the aircraft will return to its original state and begin to roll uncontrollably to the right.

Now the plane is approaching the runway obliquely, and there is still a lot of margin in the direction, so the landing direction of the plane is not the most direct problem, but in the deceleration state, the plane cannot reduce the bank angle, so it cannot Land normally.

No pilot can land sideways, which is worse than a broken wing.

Before, David saw it.If the high speed is maintained, at least Xu Cang can reduce the tilt angle of the plane's fuselage to about [-] degrees in a short time.Although this angle is still very large, but it can barely complete the landing, at least there is a chance.

But Xu Cang's operation just now proved that as long as the plane slows down, it is impossible for the plane to reduce to a bank angle of [-] degrees, even [-] degrees, and the state is even worse.This means that there is no possibility of even a little landing.

If the aircraft slows down, the effect of the rudder surface will be reduced, and it will not be able to maintain a smaller bank angle, and it will not be able to touch down.

However, if the aircraft does not decelerate, in order to maintain sufficient rudder effect to offset the rolling moment of the aircraft, the speed of the aircraft must be kept at an extremely exaggerated level, such as twice the normal approach speed.But this speed is too exaggerated, even a runway of 600 meters is not enough.

The Boeing 777 is not a Boeing 737. Huge mass means huge inertia.You must know that the end of runway 35 is opposite to an apron, where there are a large number of flights waiting at the ground due to the wind volume exceeding the standard.

If it is not done well, this will lead to the accident with the largest casualties in the history of civil aviation in the world.No matter who it is, they don't want this kind of thing to happen to them.

Although if you die, you can't care about anything.

However, David or Schneider would never want to be named the biggest butcher in the history of civil aviation.

But now, the plane can't even slow down, and it can't do without slowing down. For a while, it's in a deadlock again.

To be honest, neither Schneider nor David can understand the current situation anymore, and their cognition and level have no room for display in the current situation.Therefore, they could only follow Xu Cang's thinking, but they obviously couldn't keep up with Xu Cang's rhythm.

So, they kind of give up thinking now.

"Do we have any chance of surviving?" David asked.

Sure enough, in the end, it was still necessary to throw all the problems to Xu Cang to solve them.

Xu Cang looked neither happy nor sad: "Yes, we only need a differential horizontal stabilizer."

"Differential horizontal tail?" Schneider used to fly fighter jets, so he is obviously more sensitive to this term: "But the horizontal tail of the 777 is linked, and only some fighter jets have differential horizontal tails."

The Boeing 777 or almost all civil aviation airliners have linked horizontal tails, that is, the stroke changes of the horizontal tails on the left and right sides are the same, and they can only go up or down together.

However, if it is a differential horizontal stabilizer, it can be realized that one side of the horizontal stabilizer is up and the other side of the horizontal stabilizer is down.

This function basically only appears on fighter jets that require extremely high maneuverability.

"Xu Cang, I've flown an F-15 before, and that plane has a differential horizontal tail, but it's uncontrollable, it's all automatic." Schneider was startled and frightened, he felt that his thinking was the same as Xu Cang was simply not in the same dimension.He didn't dare to accuse Xu Cang rudely, just now Xu Cang's manipulation by switching the rudder and elevator was beyond his reach, so he was not qualified to accuse Xu Cang at all, he could only rely on his own experience to persuade.

Xu Cang's mouth moved slightly, and he said a series of words, which was the landing method he was about to complete in a while.

However, these words fell into the ears of Schneider and David like a fantasy, and they were simply unheard of.

"Xu Cang, listen to me, you can't land like this, even the flight control computer can't complete this complicated operation, the human brain is absolutely impossible." Schneider said anxiously: "You trust me, Xu Cang! "

"You can use the flight control computer, but you can't understand the flight control computer." Xu Cang's voice seemed to have no trace of human emotion: "It's like you can see me now, but you can't understand me."

At this moment, Xu Cang only felt that he had entered an unprecedented state, which was more perfect than his state at Yulong Airport.

He only felt that he was perfect and flawless, that he had transcended a state that could be described and recognized.

This is his full glory!
His unattainable new heights!
What he sees, what he thinks, he can do!
At this moment, Xu Cang was so determined!
He is God!
