Return to 2000: Captain of the Great Powers

Chapter 143 I Have No Solution! (Please subscribe!)

On the Qizhou Tower, when the lights of Shandong Airlines Flight 9451 overlapped with the lights of the runway, the tower controller who had been paying attention to the aircraft's dynamics immediately shouted: "Director, the plane has landed, and the air-ground logic has been converted."

This kind of radar controlled airport can obtain part of the aircraft's information through the data link exchange with the aircraft's transponder, including the aircraft's true air speed, ground speed, and air-ground logic status of the aircraft.

Whether the plane is in the sky or on the ground, this question seems simple, but it is indeed an extremely critical logical question, because the operation of many aircraft systems is completely different on the ground and in the air.

However, most aircraft rely on the pillar compression signal of the landing gear as the basis for the air-to-ground logic conversion.Of course, this involves the problem that the landing gear cannot be released or the water ditching.Both of these situations create problems with the undercarriage struts not being able to compress, but that doesn't tell if the plane is on the ground.

However, fortunately, this problem does not exist in the Shandong Airlines aircraft. Once the air-ground logic is switched, it will be displayed on the control radar.

The supervisor on duty did not speak, but looked at Shi Lingling who was looking out the window at the runway.He could keenly notice that Shi Lingling's originally tense body gradually relaxed after the plane landed.It seemed that it was true that her father was one of the crew members on duty.

After waiting for a while, Shi Lingling breathed a sigh of relief after confirming that the plane had indeed landed on the runway just by visual inspection.Turning around, he nodded slightly towards the supervisor on duty: "I will trouble Director Li next time."

The supervisor on duty waved his hand in a hurry: "I am responsible for reporting the needs of ground support, but the specific on-site situation is still in charge of the airport's safety committee."

"Oh, that's it." Shi Lingling didn't care too much about who was in charge, but just nodded: "I'm sorry to bother Director Li just now, I'll go down first."

In the case of an engine explosion, even if the fire alarm disappears, to be on the safe side, it is estimated that the plane will be evacuated after it stops for a while, and she has to go to the scene to see.

The supervisor on duty knew that Shi Lingling was going to the scene, so he whispered: "Miss Shi, it's inconvenient for you to walk there like this, wait a moment, I'll contact the infield car to take you there."

Shi Lingling thought for a while, and felt that what the supervisor on duty said made sense.Regardless of the fact that the runway is not far away from the tower, it would still be very troublesome to walk across with two legs.

"Well, then trouble the director." Shi Lingling did not refuse.

"It's just a small matter." The supervisor on duty was very discerning, and said with a smile, "I think I will see news about your father in the official newspaper soon."

Speaking of this, the corner of Shi Lingling's mouth turned slightly: "That will have to wait for the investigation results to come out."

Just as the supervisor on duty was about to add some compliments, the controller behind him suddenly asked in confusion: "Director, why doesn't the speed of 9451 seem to slow down?"

"What did you say?" The supervisor on duty was startled when he heard the words: "Impossible!"

As he spoke, he glanced at the runway outside the window, and could tell with the naked eye that the plane had crossed almost half the length of the runway.Then I looked down at the speed of the plane, and there were still more than 130 knots.

For the smaller Airbus 319, the speed of more than 130 knots is almost the approach speed.The approach speed of the Airbus 320 is higher, but at most it is only a dozen knots faster.

More than half of the runway was used up, yet the plane lost less than [-] knots of speed, which was obviously abnormal.

"What's the matter?" Shi Lingling hurried forward: "Is there a problem with the plane's deceleration?"

"The plane didn't slow down." The supervisor on duty watched the plane getting closer and closer to the end of the runway, feeling extremely anxious.According to the previous deceleration efficiency, it is impossible for the plane to stop on the runway.

At this moment, Shi Lingling also noticed the speed information of Shanhang Airlines 9451 on the radar screen, and couldn't help but turn pale with shock: "130 knots, why is the speed so high?"

In the cockpit of the plane, Wang Baotian also noticed that the plane decelerated too slowly, and it seemed that it had already passed the middle mark of the runway, but the airspeed indicator was still slowly descending section by section.

"Too slow, too slow!" Wang Baotian was anxious: "Automatic braking is useless, manual braking, manual braking!"

"I stepped on it, I slammed on it!" When Wu Taiming mentioned that the deceleration effect was not good, Shi Qi had already switched from automatic braking to manual braking, and almost stepped on the brakes to death.

At this moment, both the flight spoiler and the ground spoiler have been raised, the thrust reverser has also been pulled up, and the maximum manual brake has been applied, but the plane's speed drops very slowly for some reason.

"What's going on, why can't the speed drop?" Wang Baotian looked at the remaining runway that was getting shorter and shorter, and yelled.

There are only a few deceleration methods for the plane, and Shi Qi has already used them all, but they can't achieve the expected deceleration benefits at all. If this continues, they will have to rush off the runway.

Moreover, they are not a little bit worse, but very much worse.If there is only a little bit of spare speed left, then just spin around at the head of the runway, maybe you can save it.

But according to the current deceleration efficiency, they estimated that they still had a speed of 180 knots when they reached the end of the runway.What is the concept of a speed of [-] knots? It is a high speed of more than [-] kilometers per hour.

If you want to turn in place, you must use the retractable wheel, because the turning angle is very large, and only the hand wheel can complete this turning action.

But the front wheel steering is very sensitive, especially at high speeds.Therefore, the use of front wheel turning should be done at very low speeds, most of which are below ten knots.If it exceeds twenty knots, there is a risk of losing control.

The speed of twenty knots is already quite terrible, let alone one hundred knots.If the speed of [-] knots is achieved by using the handwheel to complete the rotation on the spot, the plane will undoubtedly roll over, and it is no different from courting death.

As things stand now, they don't even have a chance to risk it for the foreseeable future, and it seems hopeless.

However, at this moment, Wu Taiming found that the ECAM consultation page began to continuously refresh the alarm information: "Teacher, the No. [-] engine reversed and reported an error, the vibration value is high, and the brake temperature is overheated."

"The reverse thruster reported an error, is it because the reverse thruster is not turned on?" At this moment, Shi Qi's mind was running rapidly. As for the high vibration value of the engine, he didn't even need to look at the instrument display. The suspicion is not that the engine vibration value is high, but that the whole plane is about to fall apart.

Wang Baotian simply stopped looking at the instruments in the cabin, but raised his head to observe the outside world. He couldn't just let it go. He has survived his 36-year flying career, and can he lose his fame after retirement?

Suddenly, Wang Baotian noticed that there seemed to be no aircraft parked on the terminal apron on the left side of the end of the runway, so he pointed in that direction, turned out at the penultimate exit, and entered the terminal apron.

Shi Qi glanced subconsciously, only to see that it was pitch black, and he was not sure if there was a plane there.

"It's too dark over there, without the guidance of ground lights, I can't tell to rush there." Shi Qi immediately objected to Wang Baotian's proposal: "Besides, I'm not sure if there are any planes there."

Wang Baotian roared: "It says it's a parking lot, but most of the time it's actually used as a deicing platform for slow trains. How could there be planes?"

However, Shi Qi didn't listen to Wang Baotian at all, he didn't say half of what he said.Even if you can successfully transfer to that piece of apron, you can increase the taxiing distance in theory, but the actual increase is not much, it is tantamount to drinking poison to quench your thirst.

Seeing Shi Qi completely ignoring him, Wang Baotian was even more anxious and angrily asked, "Do you fucking understand human speech?"

At this moment, Wu Taiming's eyelids twitched: "Teacher, the brake temperature is about to exceed the limit!"

In such a high-speed situation, the brakes have been trampled to death, and the temperature of the brake pads must have soared crazily. It would be strange not to exceed the temperature.If the temperature of the brake pads is too high and lasts for a certain period of time, the brake pads may melt and deform directly. At that time, the brakes will be scrapped.

"Shi Qi, you have no choice!" Wang Baotian still insisted that his method is the last way.

However, Shi Qi would never accept this kind of gambling way out.At this moment, Shi Qi's decisive ability was demonstrated, and he was clearly going to find another way out of the way out pointed out by Wang Baotian.

When he looked up, Shi Qi even saw that the remaining runway centerline lights were about to turn red, and the length of the remaining runway was running out.

It's time to make a decision!
I saw that Shi Qi directly pressed back the extended deceleration, then released the brake, manually retracted the thrust reverser, and then pushed the thrust handle of the No. [-] engine to the front.

In this situation, Wang Baotian directly took a breath: "What are you going to do?"

"One more turn! Flaps three!" As Shi Qi removed all deceleration measures, the buffeting of the aircraft suddenly seemed to decrease a little, but as the thrust of the engine increased, the vibration of the airframe began to increase again.

After the thrust of the No. [-] engine increased, the plane began to veer to the left, so Shi Qi quickly used the rudder to control the plane's taxiing direction, keeping it on the center line of the runway.

"Teacher, you." Seeing Shi Qi's movements, Wu Taiming immediately realized that Shi Qi was going to taxi and go around, so he needed to retract the flaps.In fact, Wu Taiming didn't know whether he should do this in view of his own technical reserves, but he still chose to trust Shi Qi unconditionally, and directly raised the flap handle to the third position.

However, as soon as Wu Taiming finished his movements, he lowered his head again and found another situation: "Teacher, the fault display of reverse derivation is still there!"

Hearing this, Shi Qi's face turned pale. He had obviously retracted the thrust reverser just now, why is the reverse thrust still reporting an error?Suddenly, he thought of an extremely terrifying possibility.

On the contrary, Wu Taiming still couldn't figure out the situation, but he could vaguely feel that something went wrong.But Wang Baotian, who was sitting behind him, was keenly aware of the problem, and his face changed wildly: "The reverse push is stuck and you can't get it back, you can't get up!"

That's right, Shi Qi did have a general understanding of the failure of reverse thrust.As soon as he landed, he pulled the reverse thrust, and he pulled the reverse thrust to the full open position.However, the thruster system failed, and the actuation device did not open the baffle door for the reverse thrust of the engine to the correct position.Only when the actual positions of the thrust reverser handle and the thrust reverser device do not match will cause the reverse thrust fault to be reported.

But in many cases, as long as the reverse push handle is retracted, the faulty baffle door will also be retracted.But this time, after he retracted the reverse thrust handle, the baffle door of the thrust reverse device did not move accordingly, and it just stuck in the open position, because the thrust reverse fault message still did not disappear.

This also means that Shi Qi needs to take off with the reverse thrust of the engine. Once the reverse thrust of the engine is turned on, it will greatly cancel the forward thrust of the engine, and it will be difficult for the plane to get up.

It was based on this idea that Wang Baotian tried his best to prevent Shi Qi from taking off again.

However, Shi Qi squinted his eyes, and said in his heart, "I am the captain in charge, I will make the decision, continue to take off!"

"Damn it!" Wang Baotian cursed in his heart, but at this time, the speed of the plane had increased to close to 130 knots, and it was obvious that there was no turning back, so he could only follow Shi Qi's approach.

Shi Qi put his left hand on the side stick. He didn't know the correct rotation speed, so he could only delay the timing of the rotation as much as possible so that the rotation speed of the aircraft was high enough.

The only thing that deserves Shi Qi's luck is that because they decelerate too slowly, and Shi Qi can be considered decisive.They still had over 100 knots left at the time of the decision to take off, and it was impossible for them to gain enough speed if they accelerated all over again.

After waiting for a while, after about four or five seconds, Shi Qi saw the first red light suddenly appeared on the runway center line lights in front of him, and he knew that the last time had come.

"The last 600 meters, turn the wheel, turn the wheel!" Wang Baotian is also paying attention to the outside world, and naturally noticed the red light on the center line light. Once the first red light appears on the center line light of the runway, it means that the remaining runway is only left. 600 meters, or two thousand feet.

This distance seems very long, but in fact, the speed of the plane has exceeded 140 knots, which is 260 kilometers per hour, and the distance of 600 meters is almost the remaining time of eight seconds.

You must know that it will take some time from the start of the aircraft's wheel rotation to the departure of the dual main wheels from the ground, so the time of eight seconds is really very tight.

Shi Qi took a deep breath, he knew that the moment of life and death had come.If the two engines are normal, even under the appropriate reduced thrust operation, the speed of more than 140 knots is definitely more than enough.

But at this moment, the single engine was running, and the thrust reverser was abnormally opened, and the thrust was offset. He didn't know if he could pull the plane up.

However, he has no choice!
Almost at the moment when the plane crossed the first red light, Shi Qi began to slowly lower the stick to form a take-off attitude.However, when he clearly felt that the nose of the aircraft had left the ground, the main wheels could not leave the ground no matter what.

"I can't bring it up!" Shi Qi's complexion suddenly turned pale, and the thing he was most worried about happened.

Although theoretically, a single engine can complete the take-off action, but the impact of thrust damage caused by the partial opening of the reverse thrust is still too great.

At this moment, the aircraft is in a weird scene where the front wheels are off the ground, but the main wheels are still unable to leave the ground.

Wu Taiming's breathing stopped suddenly, and he also noticed the state of the plane.At this moment, it is not possible to force the stick roughly, not to mention that the strong stick will cause the tail to rub, and if the nose is too high, it will undoubtedly increase the air resistance, which is not conducive to the speed of the aircraft.

Wang Baotian could already see that the lights on the center line of the runway had turned to full red, which was the sign of the last 300 meters left.It took only a while for Shi Qi to turn the wheel, and the plane had already passed 300 meters.

"It's over!" Wang Baotian felt a chill in his heart.

However, Shi Qi gritted his teeth and pressed the TO/GA switch. The EGT temperature of the No. 890 engine directly rushed to nearly 56 degrees. The CFM5-[-]A engine seemed to be burning out the last bit of power, and the violent operation sounded like thunder. wrath.

The thrust limit of the engine is only limited by the exhaust gas temperature, that is, the value of EGT.After pressing the TO/GA switch, the engine has obtained the theoretical maximum take-off thrust at this moment, which is the limit of the engine.

The maximum take-off thrust is not unlimited use like the maximum continuous thrust, and it can only be used for no more than 10 minutes in the case of a single engine, otherwise the engine will not be able to withstand long-term overload operation and cause damage.

At the moment when the maximum take-off thrust was produced, the body of the aircraft, which was already trembling violently, continued to shake violently, so much that Shi Qi couldn't even hold the sidestick.

This is also the reason why Shi Qi was unwilling to use the maximum takeoff thrust before, because the thrust reverser is abnormally turned on, and the engine buffeting will increase correspondingly with the increase of engine thrust.Shi Qi didn't want to damage the structure of the body due to excessive vibration of the body, but when it came to the moment of life and death, he couldn't care less!
"Hold on!" Shi Qi roared.

However, the horizontal row of lights at the end of the runway was getting closer and closer. Just as he was about to overrun the runway, Shi Qi slightly touched the stick again. Amidst that apparently impacting noise, the main wheel of the plane left the ground at the last moment. .

As soon as the plane started to produce a real rate of ascent, Shi Qi shouted: "Stop the wheel, stop the wheel, stop the wheel quickly!"

At this point, the plane can only sustain an ascent rate of [-] feet per minute. It really has reached a critical point, and the wheels must be retracted as soon as possible to reduce flight resistance.

Of course Wu Taiming knew, even before Shi Qi called out to stop the round, he executed it after seeing a positive index on the lift rate meter.Following Shi Qi's voice, the landing gear was retracted at the same time.

As soon as the landing gear was retracted, the rate of ascent of the aircraft increased significantly, but the buffeting caused by the reverse thrust never disappeared.Still, he was up, not off the runway.

Due to the lack of thrust, the speed of the aircraft was relatively slow. Shi Qi was not in a hurry, but after seeing that the aircraft was temporarily stable, he reported to the control tower: "9451 is going around!"

"What did you say, the plane can't slow down?" On the tarmac, Li Rongxian, who got off the plane, was stunned after receiving the feedback from Shandong Airlines' transportation control: "Is there a problem with the brakes?"

"Bullshit brake problem, the brake pads are almost melted, you tell me it's a brake problem!" On the other side of the phone, Deng Wenjia directly snatched the call, and immediately scolded Li Rongxian: "What kind of plane are you, can you make it?" Do you know the reason?"

Deng Wenjia himself is the leader of the safety supervision department of Shandong Airlines. After the problem of flight 9451, Deng Wenjia, the general manager of the flight department and the safety supervision department, was the first to know.

In fact, after learning that flight 9451 was single, Deng Wenjia's mood was relatively stable.He knows Mr. Shi Qi, and he is well-known in National University Airlines, which is full of talents.Moreover, Shi Qi is not that kind of theoretical school, but someone who has actually dealt with single incidents, is an experienced person, and his own skills are excellent, so Deng Wenjia is not worried.

But just now, the plane pulled up again after touching down.According to the feedback from the crew, the plane could hardly slow down after landing, and the thrust reverser system failed. At this moment, the plane was flying with reverse thrust, and the body was always in a state of buffeting.

If the single-shot problem is still acceptable in Deng Wenjia's eyes, then the inability to slow down after landing is intolerable.The plane cannot slow down when it lands, so how can it land?

Moreover, the plane is now flying with reverse thrust, and the body is buffeting continuously. Who knows when the structure of the fuselage will fail, and it will really be over.

Anxiously, Deng Wenjia hated Li Rongxian, the representative of Airbus, so he was naturally blunt when he spoke.

At this moment, Li Rongxian was obviously panicked.He did work in a technical position, but that was many years ago, and there are not many things left now. After hearing it for the first time, Li Rongxian himself couldn't figure out what happened.

"It should be that the fragments from the No. [-] engine explosion flew out and damaged some other systems." At this moment, Li Rongxian, who was in a panic, even said a possibility that he guessed.

Normally, Li Rongxian would never say such a thing anyway. He represents Airbus, and what he says has weight. How can he say something that he is not sure about?
However, when these words fell into Deng Wenjia's ears, it was as if a pot had exploded.

"Then you mean that the explosion fragments of the No. [-] engine penetrated the body structure?" Deng Wenjia couldn't understand.

The aircraft's systems are all hidden inside the body structure. If the debris can damage other systems, it means that the structure of the aircraft's outer shell has been penetrated.Doesn't this mean that the current body structure of the aircraft has lost its integrity in a certain sense, and its strength limit will be greatly reduced.

You know, at this moment, the aircraft is still in a state of continuous buffeting, which puts forward extremely high requirements on the strength of the airframe structure, but is it because the house is leaking and it is raining overnight?
Deng Wenjia's rhetorical question made Li Rongxian realize that he had said the wrong thing, so he hurriedly said: "No, no! Give me 5 minutes, at most 5 minutes, and I will help you contact the technical department of our headquarters."

On the other end of the phone, Deng Wenjia was silent for a while, and then said: "Let me just trust you once, the plane is in very bad condition now, I hope you get a solution as soon as possible. Also, I have already communicated with the airport, if you think If necessary, you can go to the tower to communicate directly with the crew to understand the situation."

As soon as Li Rongxian heard that he could communicate with the crew directly, Li Rongxian naturally wished for it. Now he said that the information he got was all relayed from Shandong Airlines. Most Accurate Information.

"Okay, okay, how do I get there?"

Deng Wenjia snorted, "You are in seat 221, you just wait there, a car will pick you up soon."

"Okay!" Li Rongxian had just finished speaking when Deng Wenjia rudely hung up the phone.Normally, Deng Wenjia's attitude would definitely cause Li Rongxian's dissatisfaction, but now, all he has left is panic.

On the plane, after reaching 600 meters, Shi Qi chose to keep the configuration of the flaps two.After leveling, he patted Wu Taiming on the shoulder: "Go to the back and see if the second serve is pushing back."

Due to the angle of view, the engine cannot be seen from the cockpit, so people can only be sent to the cabin to see it.

Wu Taiming understood Shi Qi's meaning, immediately unfastened his seat belt, took off his earphones, and was about to go out.And Wang Baotian also stood up to make way for Wu Taiming.

When Wu Taiming got up, Shi Qi suddenly seemed to think of something, and said again: "After you go to the cabin, find Xu Cang again, ask his opinion, and call him in if possible."

Having said this, Wang Baotian's expression changed, but he quickly disappeared, and he didn't say anything more.After Wu Taiming left the cockpit, he sat down again and said coldly, "Xu Cang? Do you think he has a solution?"

Shi Qi didn't explain too much, but just said lightly: "What if?"

"If this is a Boeing plane, I can barely accept your approach. But this is an Airbus, I heard that he is the one who modified the Airbus. Such a big matter, you actually asked a kid who just changed the plane , I’m afraid you’ve gone to the doctor in a hurry.”

Although Wang Baotian was very upset when he saw Xu Cang, he actually knew in his heart what Xu Cang's strength was.He has been flying planes for more than 30 years, especially after seeing Xu Cang's Yulong Airport land, he was really shocked.

However, Boeing is Boeing, and Airbus is Airbus. Although the basic flight principles are the same, they cannot be confused.Otherwise, why would there be strict transfer training?

However, Shi Qi sighed: "Teacher, you seem to have made a mistake about one thing. Participating in the aircraft transfer training modification does not seem to be necessarily related to whether he will be able to fly an Airbus, right?"

Wang Baotian frowned: "What do you mean?"

Shi Qi said calmly: "I mean, what if Xu Cang not only knows how to fly Airbus, but also flies very well?"

In the passenger cabin, Wu Taiming came out and asked the purser in the front cabin about Xu Cang's seat, and then walked directly to the passenger cabin.After passing by many passengers with frightened faces, Wu Taiming first glanced at the situation of the No. [-] engine through the porthole in the middle of the cabin.

Sure enough, the baffle door of the No. [-] engine opened a not-so-obvious seam.Fortunately, this seam is not big, and the negative thrust generated is not too great, otherwise it would not be able to get up at all just now.

While Wu Taiming was studying the No. [-] engine, a cold voice suddenly came from beside him: "Is it necessary to wait so long for a reverse thrust failure?"

Wu Taiming's whole body trembled, and when he turned his head, he saw Xu Cang sitting on the seat beside him.I was just looking at the No. [-] engine just now, but I didn't notice the seat number, and I didn't notice it when I was standing beside Xu Cang.

"Just right!" Wu Taiming pulled Xu Cang's arm: "The teacher is looking for you, follow me to the cockpit!"

However, Xu Cang did throw away Wu Taiming's hand directly, and he pointed to the direction of the second shot on the right: "What is the reason for your go-around, is it simply a reverse thrust failure, or something else?"

Wu Taiming glanced at the passengers around him, he was hesitating whether to tell the truth in front of so many people, so he said: "How about we go to the front and talk?"

However, Xu Cang sighed heavily suddenly, this sigh was so weak that even Wu Taiming could feel the deep sense of despair.

"Is it because the plane can't slow down after landing?" Xu Cang asked softly.

It was this sentence that shocked Wu Taiming's pupils, and immediately grabbed Xu Cang's shoulder: "How do you know? No, do you know how to deal with it?"

"When you touched the ground, the throttles were all closed!" Xu Cang raised his eyelids and pointed in the direction of the No. [-] engine: "But I judged from the sound of the engine running that after the full-flap configuration was established, the engine The speed of rotation basically didn't change."

Wu Taiming took a breath: "What do you mean? You mean that after we landed, the engine was still maintaining high thrust? Something went wrong with the engine control system?"

Xu Cang didn't speak, just waiting for Wu Taiming to digest the information.

From the final approach of the plane, when it was about to land, Xu Cang felt that there was something wrong with the sound of the engine speed. Combined with Wu Taiming's reaction, it seemed that his guess was right.

Soon, Wu Taiming came back to his senses, with an extremely excited expression: "Then do you have a solution? Come with me to the cockpit and tell the teacher."

"No need!" Xu Cang pushed Wu Taiming's hand away again: "You just tell the teacher to let him turn around and land, just land on the airport."

Wu Taiming was stunned: "But the plane can't slow down, how can it stop? Isn't it going to run off the runway?"

At this time, Xu Cang put his arms around Wu Taiming's shoulders, pulled him down, and leaned into Wu Taiming's ear and said, "Tell the teacher that I have no choice. How many lives will I survive if I rush out of the runway?" , it depends on God's will."

Hearing this, Wu Taiming was shocked, he turned his head to look at Xu Cang in disbelief, but what greeted him was Xu Cang's indifferent but firm eyes.

Wu Taiming knew, Xu Cang was not joking.

PS How should the plane land, what do you think?
