On the Qizhou tower, when the lights of the Shanhang Flight 9451 flight overlapped with the runway lights, the tower controller who was always paying attention to the aircraft dynamics immediately shouted: "Director, the plane has landed, and the logic of the airfield has been changed."

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

Whether the aircraft is in the sky or on the ground is a question that seems simple, but it is indeed an extremely critical logical problem, because the systems of many aircraft are completely different from those in the air.

Most aircraft rely on the compression signal of the landing gear pillars as the basis for the logic conversion of air-to-ground logic. Of course, this involves the problem of the inability to release the landing gear or the emergency landing on water. Both situations will cause the problem of the inability to compress the landing gear pillars, but it cannot be used to judge whether the aircraft lands on the ground.

Fortunately, this problem does not exist on the Shanhang aircraft. Once the air-ground logic is converted, it will be displayed on the control radar.

The duty teacher did not speak, but looked at Shi Lingling who was looking at the runway outside the window. He could keenly find that Shi Lingling's originally tense body gradually relaxed after the plane landed. It seemed that her father was one of the flight crews, which was the truth.

After waiting for a while, Shi Lingling could only confirm that the plane had indeed landed on the runway by relying on her eyes. She turned around and nodded slightly to the duty director: "I'll trouble Director Li next."

The duty teacher waved his hand: "I am responsible for reporting the needs of ground support, but the specific on-site situation is still under the airport safety committee."

"Oh, that's it." Shi Lingling didn't care much about who was in command, but just nodded: "I asked Director Li just now, I'll go down first."

When the engine explodes, even if the fire disappears, to be on the safe side, it is estimated that the plane will still have to evacuate after the plane stops in a while. She has to go to the scene to check it out.

The duty teacher knew that Shi Lingling was going to the scene and whispered: "Miss Shi, it is not convenient for you to walk over like this. Wait for a while and I will contact the inner yard to take you over."

Shi Lingling thought about it and felt that the duty teacher said something reasonable. Don’t look at the track from the tower and see that it is not far away, if you walk over with your legs, it will be very troublesome.

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

"It's just a small matter." The duty teacher was very sensible and smiled, "I think I'll be able to see Ling Zun's news in the official newspaper soon."

Speaking of this, Shi Lingling's mouth slightly raised: "Then we have to wait until the investigation results come out."

The duty teacher was about to give a few more compliments, but the controller behind him suddenly wondered: "Director, why does the speed of 9451 seem to have not been reduced much?"

"What did you say?" The duty teacher was stunned when he heard this: "It's impossible!"

As he said that, he looked at the runway outside the window, and could tell with his naked eyes that the plane had crossed nearly half of the runway length. Then he looked down at the speed of the plane, and there were more than 130 knots.

If it is a smaller Airbus 319, the speed of more than 130 knots is almost the approach speed. The approach speed of the Airbus 320 is larger, but at most it is more than ten knots.

The runway was used for more than half, but the plane actually reduced its speed by less than twenty knots, which was obviously abnormal.

"What's wrong?" Shi Lingling hurried forward: "Is there a problem with the plane's slowing down?"

"The plane did not slow down." The duty teacher looked at the plane getting closer and closer to the end of the runway, and was extremely anxious. If the previous deceleration efficiency was based on the previous deceleration efficiency, it would be impossible for the plane to stop on the runway.

At this moment, Shi Lingling also noticed the speed information of Shanhang 9451 on the radar screen, and was shocked: "One hundred and thirty knots, why is the speed so high?"

In the cockpit of the plane, Wang Baotian also noticed that the plane slowed down too slowly. He had already passed the middle sign of the runway, but the airspeed meter still slowly descended one by one.

"It's too slow, too slow!" Wang Baotian was anxious: "Automatic brakes are useless, manual brakes, manual brakes!"

"I stepped on it, I stepped on it!" When Wu Taiming mentioned that the slowdown effect was not good, Shi Qi had switched to the automatic brake to the manual brake, and almost stepped on the brake to death.

At this moment, the flight spoiler and the ground spoiler have both risen, and the reverse push has been pulled up, using the largest artificial brake, but the speed of the aircraft is slow.

"What the hell is going on? Why can't the speed drop?" Wang Baotian yelled at the remaining tracks that were getting shorter and shorter.

There are only a few methods of deceleration for the aircraft, and Shi Qi has used all of them, but they cannot achieve the expected deceleration benefits. If this continues, they will have to rush out of the runway.

Moreover, they are not a little bit worse, but a lot worse. If only some remaining speed is left, they can just spin on the runway, and they can't say that they can save it.

But according to the current deceleration efficiency, when they reach the runway, they probably have a speed of 100 knots. What is the concept of a speed of 100 knots? It is a high speed of more than 180 kilometers per hour.

If you want to spin on the spot, you must use the closing wheel, because the turning angle is very large, and only the handwheel can complete the turning action.

However, the front wheel turning device is very sensitive, especially at high speed conditions. Therefore, the use of front wheel turning should be at extremely 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 deadly, let alone one hundred knots. If the speed of one hundred knots is used to rotate on the spot with the handwheel, the plane will undoubtedly turn over, which is no different from seeking death.

The situation is that in the foreseeable future, they don’t even have the opportunity to take risks, and there seems to be no hope.

However, at this moment, Wu Taiming found that the ECAM consultation page began to refresh the alarm information: "Instructor, the second engine reported an error in the reverse thrust, the vibration value is high, and the brake temperature is overtempered."

"The reverse thrust report is wrong, is the reverse thrust not turned on?" At this moment, Shi Qi's mind was running rapidly. As for the high engine vibration value, he didn't even have to look at the instrument display. Just at this moment, he suspected that it was not the high engine vibration value, but the whole aircraft was 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 could not surrender. He survived his thirty-six years of flying career, and could he lose his reputation after retirement?

Suddenly, Wang Baotian noticed that there seemed to be no plane parked at the end of the runway. He immediately pointed to that direction, turned out on the penultimate departure path, and entered the end apron.

Shi Qi subconsciously glanced at him and saw that it was pitch black. He was not sure if there was any plane there.

"It's too dark there. Without ground light guidance, I can't tell you to rush over." Shi Qi immediately opposed Wang Baotian's proposal: "And I'm not sure if there are any planes there."

Wang Baotian shouted: "It is said to be a tarmac, and most of the time it is used as a slow-dry deicing floor. How could there be an airplane?"

However, Shi Qi didn't listen to Wang Baotian at all, and he hadn't said half of it. Even if he could successfully transfer to the apron, it would theoretically increase the sliding distance, but in fact it did not increase much, which was tantamount to quenching thirst.

Seeing that Shi Qi completely ignored him, Wang Baotian said angrily: "Do you understand human words?"

Just then, Wu Taiming's eyelids hopped: "Teacher, the brake temperature is about to exceed the limit!"

At such a high speed, the brakes are always stepped on to death, and the temperature of the brake pads must soar wildly. It would be strange if the brake pads are not overtemperature. If the brake pads are too high and last for a certain period of time, it is possible that the brake pads will melt and deform directly, and then the brakes will be scrapped.

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

However, Shi Qi would not accept this gambling-style way out at all. At this moment, Shi Qi's decisive ability was reflected. He clearly had to find another way out from the way out pointed out by Wang Baotian.

As soon as he looked up, Shi Qi even saw that the remaining runway center light was about to appear red, and the remaining runway length was not much.

It's time to make a decision!

Shi Qi actually pushed back the extended slowdown directly, then released the brake, manually retracted the thrust device, and then pushed the thrust handle of the No. 2 engine to the front.

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

"Another circle! Flap three!" As Shi Qi removed all the deceleration measures, the vibration of the aircraft suddenly seemed to decrease a little, but as the thrust of the engine increased, the vibration of the body began to increase again.

After the thrust of the No. 2 engine increased, the aircraft began to tend to be left-sided, so Shi Qi quickly controlled the plane's skiing direction through the rudder, so that it could always be maintained on the mid-line of the runway.

"Teacher, you." Wu Taiming saw Shi Qi's movements and immediately realized that Shi Qi was going to slide and then fly again, so he needed to put the flap in the next level. In fact, Wu Taiming didn't know whether he should do this from his own technical level reserves, but he still chose to believe Shi Qi unconditionally and directly raised the flap handle to the third position.

However, after Wu Taiming finished his hand movements, he lowered his head and found another situation: "Teacher, the fault of the reverse push is still there!"

Upon hearing this, Shi Qi's face turned pale. He had obviously withdrawn the reverse push device just now, but why was the reverse push still causing an error? Suddenly, he thought of an extremely terrible possibility.

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

That's right, Shi Qi did roughly understand the fault of the reverse push. When he first landed, he pulled the reverse push and pulled the reverse push to the full open position. However, the tweet system failed and the actuator did not open the backward push door of the engine to the correct position. The actual position of the reverse push handle and the reverse push device would cause the reverse push fault to be reported.

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

This means that Shi Qi needs to take off with the engine in reverse push. Once the engine is pushed back and turned on, it will greatly offset the positive thrust of the engine and make it difficult for the aircraft to get up.

It was precisely based on this idea that Wang Baotian tried his best to stop Shi Qi from taking off for the second time.

However, Shi Qi narrowed his eyes and made a fuss in his heart: "I am the responsible captain, I will make the decision and continue to take off!"

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

Shi Qi put his left hand on the side rod. He didn't know the correct speed of lifting the wheel, so he could only delay the head lifting time as much as possible so that the plane's wheel lifting speed was large enough.

The only thing that Shi Qi is grateful for is that because they slowed down too slowly, and Shi Qi made a quick decision. When they decided to take off, they still had more than a hundred knots of speed. If they accelerated from scratch, they would not be able to increase to enough speed.

Waiting for a while, almost four or five seconds later, Shi Qi saw the first red light suddenly appear on the runway center light in front of him. He knew that the last time was up.

"The last six hundred meters, lift the wheel, lift the wheel!" Wang Baotian was 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 runway's center line light, it means that there are only 600 meters left in the remaining runway, which is 2,000 feet.

This distance looks 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 know, it will take some time from the start of the plane to the double main wheels off the ground, so eight seconds is really tight.

Shi Qi took a deep breath and knew that it was time to decide life and death. If the double-shot was normal, even with appropriate thrust reduction, the speed of more than 140 knots would be more than enough.

But at this moment, it was running a single-shot and it also received the effect of abnormally opening of the reverse push. The thrust was offset, and he didn't know if he could pull the plane up.

But, he had no choice!

Almost immediately when the plane passed the first red light, Shi Qi began to slowly take the pole, forming a take-off posture. However, when he clearly felt that the nose of the plane had left the ground, the main wheel could not leave the ground anyway.

"I can't take it!" Shi Qi's face suddenly turned pale, and the thing he was most worried about was still happening.

Although theoretically, a single engine can complete the takeoff action, the thrust damage caused by opening the reverse pushing part is still too great.

The plane is now in a strange scene where the front wheel is off the ground, and the main wheel is still unable to leave the ground.

Wu Taiming's breathing suddenly stopped, and he also noticed the status of the plane. At this moment, he cannot force it roughly. Not to mention that the tough belting of the pole will cause the tail to be wiped, and if the nose is too high, it will undoubtedly increase air resistance, which is not conducive to the growth of the plane.

Wang Baotian could already see that the lights on the midline of the runway had turned all red, which was the sign of the last three hundred meters left. It was Shi Qi's time to lift the wheel, and the plane had already rushed over three hundred meters.

"It's over!" Wang Baotian felt cold.

However, Shi Qi did grit his teeth and press the TO/GA electric gate. The EGT temperature of the No. 2 engine rushed directly to nearly 890 degrees. The CFM56-5A engine seemed to burn out the last bit of power, and the violent operation sound was like the wrath of thunder.

The engine's thrust limit is only limited by the exhaust temperature, that is, the EGT value. After pressing the TO/GA switch, the engine obtains the theoretical maximum take-off thrust, which is the engine's limit.

The maximum take-off thrust is not as unlimited as the maximum continuous thrust. It can only be used for no more than ten minutes in a single-engine situation, otherwise the engine will not be able to withstand long-term overload operation and cause damage.

At the moment when the maximum takeoff thrust was generated, the aircraft body, which was already trembling sharply, continued to shake violently, so shaking that even made Shi Qi unable to hold the side pole.

This is also the reason why Shi Qi was unwilling to use the maximum take-off thrust before. Due to abnormal opening of the reverse thrust, the engine thrust will increase accordingly as the engine thrust increases. Shi Qi was unwilling to damage the body structure due to excessive body thrust, but at the moment of life and death, he didn't care about so much!

"Stand it!" Shi Qi roared wildly.

However, the cross-row lights at the end of the runway were getting closer and closer. Just as he was about to rush out of the runway, Shi Qi had another slightly slid pole. In that obvious impact, the main wheel of the plane left the ground at the last moment.
