Return to 2000: Captain of the Great Powers

Chapter 191: The Hades Wipes Himself!God has no way! (Please subscribe!)
"What did you say?" The responsible captain's face changed wildly in an instant, and he pushed the steering wheel, but no force could be felt on the steering wheel, it was light.

"Not good! It's empty!" The second captain also realized the seriousness of the problem.

Due to the deep stall, the airflow that the aircraft originally attached to the wing surface has been separated from the wing surface in a large area, and there is only turbulent airflow that is difficult to generate lift on the rudder surface.And because of the separation of the airflow, the pilot can't feel the correct stick force when manipulating the wing surface.

The reason why there is rod force is that it is due to the aerodynamic load formed by the airflow on the rudder surface.Today, the aerodynamic loads are gone, which shows how serious the separation of the airflow is.

Under such conditions, at extreme points, even the airfoil will lose the ability to generate lift.

"Why did the plane not shake the stick when it stalled like this? Besides, why didn't the plane automatically correct itself?" The second captain roared, the fear in his eyes couldn't be concealed.Now that the steering wheel of the plane is in neutral, and the airflow separation is so serious, the stall shaker warning of the plane should have sounded long ago.

The chattering of the steering wheel just now is not the stall shaking warning of the aircraft, but the turbulent flow on the surface of the rudder surface under the separation of the airflow is constantly impacting the rudder surface, and the vibration of the rudder surface is fed back to the steering wheel.

It is for this reason that the chattering on the steering wheel presents a fine but not strong feature, which is quite different from the performance of the stall shaker warning.

Stall and stick shake are pretty much inscribed in the genes of pilots.But the current situation is almost conceivable by the second captain, that is, under the deep stall, the plane began to fall straight down.This level of stall is almost never encountered in actual flights, even if it is artificially produced, it is very difficult.

Modern large airliners are actually quite advanced, and their stability is extremely powerful.In fact, even in a severe stall, if there is no intervention by other factors, the large airliner will slowly recover from the stall by itself, but the loss of altitude and the time consumed will be much higher than that of human intervention.

Therefore, even if the pilot cannot really control the plane due to air separation, in fact, according to common sense, the plane should slowly and automatically correct itself.

It was for this reason that at such a high altitude the second captain was not so nervous at first.In flight, altitude is everything, and with altitude you can solve many things.

But in fact, it has been a short period of time since the plane fell just now, but the plane has not shown any signs of recovery, which is too strange.

"The plane is now seriously icing, and the stall speed of the plane has been greatly increased." Xu Cang shouted: "In the case of severe icing, the stall shaker warning that comes with the plane may not be able to detect it."

"It's too fast, too fast, why is the plane icing so fast?" Previously, it never took more than 2 minutes from the time the wing and pod anti-icing switches were turned off to the time the plane entered a stall state.It was during these 2 minutes that the accumulated ice layer caused the aircraft to lose a lot of lift, so that it entered a stall state in advance.The captain in charge was in a state of confusion at the moment, he had never encountered such an exaggerated stall: "Xu Cang, what should we do?"

For recovering from a stall, that's pretty much the foundational skill of any pilot.Of course, this recovery procedure is not complicated.Since the essence of the stall is that the angle of attack of the aircraft is greater than the critical angle of attack, it is sufficient to artificially reduce the angle of attack of the aircraft.

The most common and direct way to reduce the aircraft's angle of attack is to eject, so in most stall situations, the first action to recover from the procedure is to eject.

However, the current situation is that due to the severe air separation, the pitch operation on the steering wheel can indeed be reflected on the elevator.However, the change of the elevator cannot generate enough torque to control the pitch of the aircraft without the action of the airflow, which is the most fatal.

"No matter how serious the stall is, it won't cause such a serious air separation. It must be caused by ice accumulation, so to solve the stall problem, we must first solve the ice accumulation problem." Xu Cang's mind was still very clear at this time.

A deep stall will indeed cause airflow separation on the rudder surface, but now the rudder surface effect of the elevator almost disappears only in the attitude of minus five degrees, which is obviously abnormal.

Theoretically, even in the case of a vertical fall, the elevator can generate a corresponding moment, but this moment is extremely limited.

Such an extreme situation occurred under the condition that no complete separation of the airflow would obviously occur, so there can only be one explanation, that is, a large amount of ice has accumulated on the elevator, and the thickness of the ice layer has reached the point where the surface structure of the elevator has changed. .

Under normal circumstances, there will be no situation where the elevator loses the rudder surface effect now, unless the rudder surface fluid structure of the elevator has undergone a major change.

Therefore, don't think about solving the stall problem in one step, because before that, there is still the problem of ice accumulation ahead, which is the root cause of everything.

However, the only good news is that their altitude is sufficient, and the altitude of [-] feet provides Xu Cang with a precious opportunity to correct everything.If the accident occurred at an altitude of only [-] feet, then Xu Cang could basically take his hands off the steering wheel and wait to die!
"Are the wings anti-icing?" The second captain's objection to the anti-icing of the wings is not so great at this time. He can see that ice accumulation has become the top priority, and he even prepared the ending of actively releasing the pressure. : "Can the falling speed of the plane catch up with the rising speed of the cockpit?"

In the second captain's mind, as long as I descend fast enough, the cockpit depressurization will not be able to catch up with me.

"Now open the manual switch of the outflow valve, and close the controller of the outflow valve." Xu Cang said loudly: "Open the wing anti-icing switch, and turn off all the components."

Due to the difference in the supercharging system of the 747, if it is on the 737, the supercharging mode selector should be turned to manual, and then the outflow valve should be closed.

"You want to turn off all the components? We can keep them. If the fault light turns on later, we don't care. Why do you want to turn it off?" the second captain was puzzled.

"The components will take away part of the bleed air for wing anti-icing. Now we need to give priority to ensuring the effect of wing anti-icing. After manually closing the outflow valve, we can minimize the rate of slow pressure release, so that even if the pressure is released, the It will release pressure at low altitudes, and the impact won't be huge."

The 747's pressurization or cabin height adjustment logic is implemented through outflow valves and components.That is, components are used to provide pressurized air in order to cope with the thin air pressure in the high-altitude environment, and the reaction to the height of the cockpit is to reduce the height of the cockpit.However, it is impossible for the aircraft to be pressurized all the time. For example, when it is descending, the aircraft should actively release the pressure. Otherwise, many times when it lands, the cabin door cannot be opened due to the pressure difference.

However, the active decompression of the aircraft is strictly calculated by the computer in the automatic mode. It releases the pressurized gas in the cabin by opening and closing the outflow valve, thereby changing the height of the cabin.

At this time, Xu Cang used manual intervention to close all the outflow valves used to release pressurized gas.Since part of the pressurized gas remains in the cabin at this moment, the air pressure altitude of the cockpit is still lower than that of the outside world.

However, even if all the outflow valves are closed, the cabin itself is not completely sealed, and the pressurized gas in the cabin will still escape to the outside of the cabin under the action of the pressure difference, which makes the cabin altitude continue to increase.

However, the escape of pressurized gas caused by the fine gaps in the engine room itself is small and slow, so compared to the faulty rapid decompression, the artificial decompression set by Xu Cang is also slow.

In Xu Cang's vision, he wanted to solve the problem of ice accumulation during the slowly formed decompression time.

The second captain just hesitated for a moment, and then quickly accepted Xu Cang's opinion, without even taking action from the responsible captain. The trap closes completely.

After confirming that the outflow valve is completely closed, the responsible captain operates simultaneously to fully open the wing anti-icing valve and close all components at the same time.

"Can the wing anti-icing really melt the ice in a short time?" The second captain was worried: "Now it's not just the large wings that have serious ice accumulation, but also the horizontal stabilizer elevator. The wing anti-icing effect is not good. What should we do when we get to the elevator? Our altitude is very high, theoretically it can last for seven to eight minutes, but the speed of our aircraft is also increasing, and the aircraft will soon overspeed, and the structure of the aircraft fuselage cannot withstand a long time speeding."

It is true that the second captain does not know the exact airspeed now, but this kind of continuous dive can be imagined with his feet, and the speed must keep increasing. Overspeed is only a matter of time.

Temporary overspeed is usually harmless, but prolonged overspeed can cause serious damage to the fuselage structure, and even mid-air disintegration is not impossible.

"Wing anti-icing will definitely not be able to melt such a degree of ice accumulation in a short period of time, but in the high-speed friction between the volcanic ash and the fuselage, not only will the electric charge be accumulated, but also a large amount of heat will be generated, which will help eliminate the accumulated ice on the fuselage. ice."

The second captain was stunned, and then woke up like a dream. He didn't expect that there was such a relationship here. How could he forget about the heat generated by friction?Even friction with air can generate a lot of heat, let alone friction with volcanic ash.

Xu Cang stretched out his left hand, touched the handle of the speedbrake, and then slowly pulled it up: "However, we need to control the speed within a reasonable range."

According to Xu Cang's thinking, he really hoped that the plane could maintain a high speed, but the speed should not be too high, otherwise there would be the problem that the second captain said just now that the continuous overspeed would overwhelm the fuselage structure.

Therefore, Xu Cang needs to use speed brakes to restrict the increase in speed.

"Will the height be insufficient if the speedbrake is pulled?" The second captain expressed his concern.

The speedbrake can indeed control the speed of the aircraft to a certain extent, but if the speed does not increase, it will also cause the aircraft to descend and increase again.Originally, the altitude of their plane was quite sufficient, but the speed brake was pulled, and the descent rate increased again. It is hard to say whether the follow-up is not enough.

"There is such a problem!" Xu Cang said as the second captain saw his fingers touch the fuel switch, and in an instant, the second captain's expression brightened.

The 747 has the function of dumping fuel in the air, and the fuel will be atomized when draining the fuel, so as to minimize the hazards of fuel draining.However, even if the fuel is atomized, there is still some damage to the area below, but it is only a matter of degree.Therefore, in civil aviation, a special oil discharge area is set up for the operation of oil discharge in the air, that is, under normal circumstances, the oil discharge in the air can only be carried out in the specified oil discharge area, and the area where the aircraft is now must not be used for oil discharge. District.

However, even if the oil was not released in the oil release area, the second captain was actually not that worried. After all, this regulation is not dead. For the safety of the aircraft and the people on board, it is acceptable to break some regulations appropriately.

It's just that the second captain wanted to know Xu Cang's meaning of releasing fuel in the air.

The captain in charge obviously also noticed Xu Cang's action, and immediately pointed out involuntarily: "Xu Cang, do you want to drain the fuel?"

"The plane is too heavy, and the speedbrake is pulled. If you want to control the rate of descent, it's better to put some fuel on the plane and make the plane lighter." Xu Cang said lightly.

"You really want to make the descent rate smaller?" the second captain shouted.

Xu Cang did not hide it: "There are too many problems caused by the volcanic ash, so many that the slightest negligence will cause the plane to crash, so I think it is better to end the flight as soon as possible."

Even Xu Cang felt exhausted at this moment.He has indeed dealt with many special cases, all kinds of them, but most of the special cases are only limited to one part, although this does not affect the difficulty of dealing with special cases, but Xu Cang can focus on a certain part of the fault .

But the volcanic ash incident didn't say how difficult it was, but its complexity was beyond Xu Cang's expectations.Almost as long as it is within the volcanic ash, there will be countless troubles.Before one is dealt with, the other just pops up, and there is no end at all.

It is true that Xu Cang still has some corresponding countermeasures so far, but this does not mean that Xu Cang can continue to deal with it like this in the future.

He was tired, and he also began to fear that he had hit the ceiling of his mental strength in this incident.Xu Cang is not afraid of difficult special circumstances, just like the previous 1566 elevator felt that there was a problem with the centering device, and after the second pull, it almost crashed at an extremely exaggerated elevation angle.

The difficulty of that special relationship was unprecedented, but for Xu Cang, the degree of suffering was far less than this time.Because, in the 1566 special situation, there was not even 5 minutes from the real crisis to the landing, and it was only limited to manipulation, and there were no other factors to affect Xu Cang.

Xu Cang has unlimited space to display his excellent technical ability to deal with special situations.But this time is different, failures of different systems come one after another, and each of them is very difficult, Xu Cang is not the kind of energetic person in the first place, under such torture, Xu Cang feels that he has reached his limit.

Now that it's time to make a decision, why doesn't Xu Cang fight for himself?
"Are you going to make an emergency landing in the Pacific Ocean?" the second captain suddenly shouted.

That's right, controlling the rate of descent can be done by draining oil, which is a reasonable reason.However, in the inspection of ditching, it is also required to discharge oil in the air first, so as to reduce the speed during ditching.

Due to the extremely long voyage this time, this 747 carries a large amount of fuel, so there is a lot of room for weight loss.Moreover, forced landing is a very dangerous thing. It is common for the fuselage to break accidentally and cause an explosion. It will not produce too violent explosion.

It was precisely because he knew that there was such a step in ditching, the second captain realized something was wrong when Xu Cang started to release oil in the air.And the fact is the same, Xu Cang just wanted to make a forced landing at sea.

Xu Cang hummed, looking quite calm: "Although theoretically the concentration of volcanic ash will be lower in a low-altitude environment, it cannot fall on land airports, and circling at low altitudes is just a needless consumption of our minds. And Well, the volcanic ash at low altitude does not really mean that there is no problem. When it is broken, you will suffer from it! Will you believe me, I will make this forced landing at sea!"

The responsible captain and the second captain immediately looked at each other, both of them looked nervous.Good guy, Xu Cang is putting all his eggs in one basket. He plans to switch to an approach directly after this dive. This kind of courage is really unstoppable for thousands of people!
Even though it was known that there was no chance at the land airport, and even though the proposal of forced landing at sea was proposed by the captain in charge, at this time, the two captains were silent, and no one dared to express their opinions.

This decision was too heavy, so heavy that the two felt overwhelmed.

It lasted like this for more than a minute, and suddenly, the steering wheel, which had been chattering continuously, suddenly began to reduce the chattering amplitude, and after more than ten seconds, the steering wheel actually calmed down directly.

Xu Cang gently moved the steering wheel, and could feel the lever force feedback from the steering wheel during the manipulation.Due to the very high speed of the aircraft at this time, the force of the stick was still relatively heavy. Xu Cang's movements only made it move slightly.

"Okay, the rudder effect has recovered?" The captain in charge was immediately overjoyed when he saw Xu Cang's actions.He never expected that the ice accumulation would be removed so quickly, with obvious results in less than 2 minutes.

However, at this moment, the plane is rubbing against the volcanic ash at a relative speed of more than [-] kilometers per hour, and the heat energy that can be generated in it is quite huge.Even though a large part will be blown away with the airflow, the remaining energy is enough to melt the ice.

After the rudder surface effect recovered, Xu Cang adjusted the trim slightly backwards, and retracted the speedbrake at the same time.Lifting the speedbrake in this high-speed environment will still be burdened by the fuselage structure, it is better not to use it or not.

"Do you want to turn off the wing anti-icing and turn on the components?" Seeing that the rudder surface effect is restored and the stall shaker warning is not triggered, it means that there is no problem with the angle of attack at this moment, and the second captain is thinking about restoring the boost to the aircraft pressure.

Xu Cang glanced at the cockpit altimeter. At this moment, the cockpit altitude is close to 1000 feet, and there are still more than [-] feet to release pressure. Less than [-] feet per minute, which means more than two minutes before decompression.

At this moment, the aircraft's barometric altitude was below [-] feet, and the rate of descent was approaching [-] feet per minute.Xu Cang glanced at the display of the outside temperature, and immediately shook his head: "No way! It's still icy outside now, wait a little longer!"

After finishing speaking, Xu Cang saw that the overall situation had been decided and that the forced landing at sea was imminent, so he immediately said to the captain in charge: "The cabin announced that the plane will be forced to land after 10 minutes of freezing, and the cabin should be ready."

Speaking of this, Xu Cang didn't even seek further advice from the two captains on whether to make a forced landing at sea.Anyway, here with Xu Cang, Xu Cang's mind has been made up, what he has to do is to inform the two of them of his own thoughts, instead of asking for their consent.

In many cases, Xu Cang is not a strong person, but when he is flying special feelings, Xu Cang is a dictatorial person!
The captain in charge and the second captain looked at each other. After five or six seconds of silence, the captain in charge suddenly sighed. He didn't say anything, but switched the transmitter of the communication panel to the PA position. , Immediately used the passenger radio to convey the decision to make a forced landing at sea.

During this period, the second captain did not have any objections, which means that he also accepted Xu Cang's opinion of forced landing at sea.

Ditching at sea is indeed a dangerous move, but after thinking about it carefully, this is their only way out now.Moreover, the most important thing is that Xu Cang has experience of forced landing at sea, and it is a successful experience, which is undoubtedly a huge advantage.

"Xu Cang, how sure are you of making an emergency landing at sea?" asked the captain in charge.

Xu Cang shook his head: "No one is sure about ditching at sea. That's right, I have succeeded once before, but due to the huge chance, even if I do it again, I am still not sure. Moreover, it is night , I can’t see the situation on the sea surface clearly, which is not good news. However, we can roughly determine the direction of entering the water through the wind direction, and then make precise corrections before entering the water.”

The forced landing at sea had to follow the waves into the water, but now the sky was covered by volcanic ash, and there was not even a little starlight or moonlight left. Xu Cang could only rely on the lights of the plane to make corrections at the last moment.

Although Xu Cang said so, but it fell into the ears of the second captain, which made him heave a sigh of relief.If Xu Cang agrees to it all, he will be worried, because as Xu Cang said, the difficulty of ditching at sea is too high. very convincing.

At least Xu Cang made his own judgment and response to the problems he might encounter.

While discussing the forced landing in the cockpit, the outside temperature rose to ten degrees after the plane broke through 1 feet.This is a node that Xu Cang is waiting for.

At this moment, the altitude of the plane's cockpit is almost [-] feet!

"Turn off the anti-icing of the wings, keep the anti-icing of the engine, open the components, and close the manual switch of the outflow valve." Xu Cang also slowly moved the stick to reduce the descent rate of the aircraft while commanding.

Above ten degrees is recognized as a non-icing condition, and as the altitude continues to decrease, the temperature will continue to rise, so even if there is still a little rain, there will be no more ice accumulation in the flying altitude after that Therefore, the wing anti-icing is naturally useless.

However, just in case, Xu Cang still kept the engine anti-icing. After all, the bleed air consumption of this engine anti-icing is not large, and there will be no problems with the bleed air components.

The captain in charge had been waiting for a long time, and immediately turned off the wing anti-icing according to Xu Cang's instructions, opened the components, and finally changed the pressurization mode to automatic.

Just as the captain in charge was operating according to Xu Cang's instructions, the PFD airspeed indicator, which had already reached the indicated airspeed of 350 knots in the overspeed zone, suddenly jumped to 320 knots, and then the overspeed warning, which was always ringing, also directly Disappeared.

These changes made Xu Cang startled, and after reacting for a while, Xu Cang finally showed a smile.It seems that there are some other benefits of diving at high speed, such as blowing away the obstruction in the pitot tube.

"The airspeed seems to be normal?" The second captain leaned over, feeling a little excited.If you continue to fly down with an unreliable airspeed, it's not that you can't fly, it's just that it will cause a lot of trouble.Now that the airspeed has returned to normal, it is a lot less troublesome.

"Notify Jakarta control that we are about to make a forced landing at sea, and ask them to pay attention to the position of our ELT signal." Xu Cang instructed the captain in charge.

ELT is an emergency locating device, which can continuously send out help signals to allow rescuers to provide positioning.Xu Cang was not very confident in Indonesia's sea rescue capabilities, so he needed to be reminded.

"Okay!" The captain in charge immediately agreed.

At this moment, the passenger cabin was already in chaos. Passengers hurriedly put on life jackets under the command of the flight attendant, and Song Xinyang's face was extremely gloomy. How could he be so unlucky to have an emergency landing at sea?

At an altitude of [-] feet, at this time, the flaps of the aircraft have been put to the thirty position, which is the configuration of the flaps during the forced landing at sea.

Then, the near-ground landing gear override switch and the near-ground terrain override switch are set to the override position, and at the same time the component controllers are all closed, the manual switch of the outflow valve is set to the open position again, and at the same time, all the outflow valves are manually closed.

The meaning of closing the outflow valve this time is completely different from the previous one.Before, it was to let the pressurized air in the cabin escape as slowly as possible, but this time the outflow valve was closed to seal the plane. After falling into the water, the seawater would not seep into the cabin too quickly, buying more time for evacuation .

At an altitude of [-] feet, Xu Cang could vaguely see some light spots reflected on the sea surface, but under the cover of volcanic ash, the sky could only shed some silver light from the gaps, so the light spots just existed. Does not have any spatial reference significance.

Of course, being able to see the sparkling light on the sea means that the concentration of volcanic ash is relatively low at this height.Therefore, Xu Cang felt a little relieved and first pushed up the throttle of the No. [-] engine, which had never been faulty, so as to reduce the steep descent rate of the plane.

Then, Xu Cang tentatively pushed the accelerators of the No. [-] and No. [-] engines.These two engines had surged before, and the reason was of course the volcanic ash.However, in the previous dive environment, Xu Cang kept the two engines in the slow car, which was considered a pretty good protection.

At this moment, the concentration of volcanic ash around the aircraft was greatly reduced, and the No. [-] and No. [-] engines began to slowly increase their thrust under the forward push of the thrust handle.Xu Cang's idea is very simple, even if only these two engines can provide about half of the reduced thrust, it is quite enough for him.

However, what made Xu Cang happy enough was that there was no obvious abnormality when the two engines were added to the thrust level slightly lower than the No. [-] engine, but the vibration value was slightly higher than the No. [-] engine, but it was still within the limit Inside.

First, the blockage of the pitot tube was eliminated, and then the No. [-] and No. [-] engines, which were originally surging, remained strong. In the case of a rough road before, it is always good news for double happiness.

At a height of [-] feet, Xu Cang has already turned the flight direction of the plane to the downwind side. At the same time, according to the descent rate, the plane will enter the water in more than a minute. After entering the water, all the fuel control switches are turned off, all the engine fire alarm switches are pulled out and rotated to the stop position and held for more than a second, and finally the slide and life raft are released to evacuate the plane, understand?"

Prior to this, Xu Cang had already shut down the air dump.Although he had already planned to make a forced landing at sea, Xu Cang did not push himself to the point of breaking the boat. He also exposed the amount of oil for nearly an hour.Therefore, after entering the water, the fuel control switch and fire alarm switch should all be operated to prevent fire and explosion.

The captain in charge must have no problem, and nodded immediately: "Leave everything to me!"

"En!" Xu Cang nodded, and looked at the wind direction and speed. Fortunately, the wind direction and speed here are very stable, and the plane is already below [-] feet at this moment. Even if it goes downwind, the wind speed should not change much. .

It is quite rare for the low-altitude wind direction and wind speed to change sharply like the 1566 encounter before.

He opened and closed his lower five fingers again. To be honest, even though he succeeded once, Xu Cang was still quite nervous.Moreover, from the actual situation, today's forced landing at sea is more difficult than the forced landing off the coast of Qizhou in 1566.

First of all, the light is darker this time, and because it is far away from the sea, the sea here is more windy and choppy. If you are not careful, the fuselage of the plane will break.

Although Xu Cang took the initiative to take this flight before to show off his technical ability, but if Xu Cang knew in advance that he was dealing with such a special situation, he would not have come anyway.

At an altitude of [-] feet, the captain in charge made the final announcement to the passengers, reminding them to prepare for collision.

Two hundred feet high!
At this altitude, the powerful landing lights could vaguely shine on the undulating sea surface, but it was quite unclear.Xu Cang knew that the moment to decide the outcome was approaching, even the responsible captain and the second captain couldn't help holding their breath.

Everyone in the cabin lowered their heads and hugged their legs in anti-collision postures, while Song Xinyang's breathing was extremely rapid, and he knew that the next ten seconds would be the difference between life and death.

One hundred feet high!

At this moment, even Xu Cang, who is as quiet as he is, is concentrating his mind, staring at the outside, waiting for the moment when the landing light shines on the sea surface for him to make the final correction.

This time is very short, he must react at the first moment and make the most correct manipulation.

But at this tense moment, Xu Cang only felt that something bumped his cheek slightly, and then it seemed that water droplets burst, and Xu Cang's face was stained with water.

If someone else was holding his breath right now, why would he care about the water droplets?Maybe it's condensation from the air-conditioning system in the cockpit, which is not uncommon.

However, what a sharp person Xu Cang was, his first thought was not the condensed water droplets of the air-conditioning system, but he moved his gaze from the front of the plane to the corner of the right front windshield, the corner where water seeped before.

From the discovery of this water seepage problem, it was covered by a series of problems, and then it was followed by the forced landing at sea, so Xu Cang has never had the energy to take care of this problem.

Of course, even if he had the energy, he couldn't manage this problem.Many faults on the aircraft are limited to conditional problems and cannot be solved at all, especially hardware problems.

Faults can often only be isolated, preventing them from further compromising the flight.In Xu Cang's memory, there seems to be no specific solution to the problem of water seepage from the windshield's leaky sealing.

In fact, when Xu Cang discovered this problem, he always had doubts.Generally speaking, such low-level problems as the windshield is not tightly sealed will not happen.

Since this problem occurs, it should be caused by other problems.

If it is said that a good windshield will basically not cause water seepage, can it be said that this water seepage windshield is actually a problem.

Xu Cang can understand this logic, because during the previous volcanic ash flight, the induction between the external charge and the heating wire in the windshield would cause a very obvious windshield arc.

In most cases, this kind of arc is not a problem, but if the arc is too dense and severe, it will have some negative effects on the windshield.

For example, the cracking of the outer windshield may not necessarily be due to the impact of a large volcanic rock, but may also be due to the overheating of the windshield.So, since the outer layer of glass may have problems under the influence of the windshield arc, is it true that the inner layer of the windshield already has problems, and then the water seepage problem of poor sealing occurs in rainy weather?
However, according to the previous visual inspection, there is no problem with the inner windshield, which means that the problem with the inner windshield is in a very hidden corner, such as
Xu Cang turned on the map light on the side without hesitation, and in an instant, the cockpit was bright.

This kind of behavior surprised the nervous captain. The light in the cockpit is too bright, which will affect the view outside. This is about to enter the water. What the hell is Xu Cang doing?
But before the captain in charge had time to ask, Xu Cang, under the sufficient light, suddenly found a small undetectable crack in the place where the water seeped in the lower right corner of the windshield.

Xu Cang's heart almost stopped at this moment, and without hesitation immediately, he slammed up the accelerators of the three engines.

Go around!Can't fall!
Due to the low altitude, the thrust change of the turbofan engine lagged slightly, and the weight of the 747 was quite large. Even with the throttle almost full, the belly of the plane still hit the top of the waves.However, under the powerful thrust of three Pratt & Whitney 4056 engines, this behemoth soared into the sky after setting off a huge splash, and disappeared without a trace.

The captain in charge didn't react to Xu Cang's go-around action for a moment, the atmosphere was so heightened just now, and the desperate words had already been released, how could he retreat before the battle?
However, after a very short period of shock, the captain in charge still performed his duties and retracted the flaps by fifteen.Since it was a forced landing at sea, the landing gear was originally retracted, but there was no need to retract it.

After finishing the action, the captain in charge was just about to ask the teacher for the crime, but Xu Cang pointed to the corner of the right front windshield with lingering fear: "Take a good look!"

"What?" The captain in charge turned his body, looked closer to the corner of the right front windshield, and suddenly gasped, there was actually a thin crack in the corner.

This shows that the inner windshield has actually been damaged. If it entered the water rashly just now, the right front windshield would be shattered under the impact of the waves, and then the sea water would pour in. Not to mention the people in the cabin, anyway, the three people in the cockpit would surely die.

"It's almost, we're all going to die!" Even after the go-around, Xu Cang's heart was still pounding, and he was only a few dozen feet away. If he reacted a little slower, they would have already Drowning in the sea and waiting to die.

The responsible captain's face was as golden as paper. He was actually annoyed at Xu Cang's retreat just now, but he didn't expect that Xu Cang knew the details and saved their lives before the gate of hell.

However, after the initial ecstasy of the rest of his life, a thought arose in the captain's mind.Now there is something wrong with the windshield, and the forced landing at sea is no longer possible. Doesn't that mean that another road is broken?

The Soekarno-Hatta Airport and Changi International Airport on the road can't be counted on, and now the desperate sea landing is a dead end. Is there really no way to go to heaven and no way to go to earth?
The responsible captain silently turned his head to look at Xu Cang. At this moment, like a god, Xu Cang, who was always able to find life, also showed confusion.

Yes!It doesn't work on land, and it doesn't work at sea, so what should we do?
At one point, even Xu Cang couldn't see the way ahead!

　It should end tomorrow, it should!What do you think should be done?There are already hints in the previous article!
