Return to 2000: Captain of the Great Powers

Chapter 402 This is China Air Force
Under the dive, Xu Cang only felt his world spinning and his mind was in chaos.

The reason why airplanes are afraid of spirals is because the energy accumulation is too fast, the speed will increase very fast, and the speed of the dive and fall is also extremely exaggerated, and the airplane is easy to disintegrate due to structural pressure.

However, now that the plane has not encountered too much structural pressure, Xu Cang is the first to be unable to bear it.

In any case, the structural strength of passenger aircraft is far less than that of fighter jets.A fighter jet can make a few more turns, but an airliner can't. If it makes a few more turns, it's easy to get out of the way, and the ending we have is only one direction of disintegration.

Fortunately, the person sitting on the left is not an ordinary person. Although Richard Bayer's thinking is slower than Xu Cang's, he is capable after all.The main reason is that he was deeply confused about how to enter the spiral by mistake. For a large airliner, entering the spiral itself is a relatively difficult act. Usually, it stalls first before entering the spiral. How can it be so unreasonable now? of?
Of course, just now he had obviously lowered the throttle, but in terms of actual feeling, the No. [-] engine had greatly increased the throttle.

However, this is only judged from the body feeling and running sound, after all, there is no engine data to support it.

Or is the engine control system having problems like the flight control computer?

He didn't have time to think about this problem, even if he didn't understand why this happened, but after turning around, he could only accept the fact that the plane was indeed in a spiral.

As long as this is confirmed, the following spiral recovery procedure will suffice, which is common in flight.

Richard Bayer turned off the accelerator, which was a very routine and standard operation, but when it fell into the eyes of Xu Cang next to him, he felt his eyelids twitch wildly.

Xu Cang is in a bad state now, he can't even move his lips, otherwise he would have reminded him a long time ago.

Richard Baier still didn't think enough.Since he suffered a loss just now, when he obviously closed the throttle, but turned into the No. [-] engine slamming the throttle, then he should have thought that there might also be a problem with the thrust control.

The engine control of a large airliner is not a simple diesel engine. Its control system is very complicated. To be precise, the position of the throttle lever corresponds to the thrust, but this correspondence is not completely consistent.

Because the engine control system will slightly correct the speed according to the flap configuration, external temperature, airspeed and other data, which leads to slight differences in the thrust represented by different times even if the throttle lever is at the same position.

However, this kind of corresponding relationship can generally be regarded as such, after all, the fine-tuning range of the thrust speed will not be very large.

The signal of the throttle lever basically drives the electric brush to generate different electrical signals, which are transmitted to the control system to adjust the thrust.

That's right, the engine also adjusts the data through electrical signals.

Since it can be suspected that there is a problem with the flight control computer, why can't it be extended, and there is also a problem with the engine control system?
Especially when there are lessons learned from the past?
Under such speculation, although Richard Bayer's operating procedures are standard, but because of the confusion of the corresponding relationship on some engine control systems, the closed throttle may become the gas pedal, isn't it proper? the reverse operation?

So, even if the throttle had to be pulled back to get out of the spin, Richard Beyer probably should have moved a little slower to give the engine control system time to react.

Of course, Richard Bayer's actions were actually not big at first, but something went wrong, and this matter is very metaphysical.

However, Richard Bayer was not aware of this section, Xu Cang knew as long as he knew it. If the engine speed increased abnormally, Xu Cang had to do his best to inform Richard Bayer that the fuel supply might need to be cut off directly. up.

No matter how confused the engine control system is, if the fuel supply is directly cut off, the plane will definitely stall.In the follow-up, after the spiral is recovered, an emergency air start is carried out. After all, their height is sufficient, and the engine itself has no hardware problems except the control system, which meets the conditions for an air start.

However, perhaps the sky gave Xu Cang the last sympathy. After Richard Bayer moved the accelerator a little recklessly, there were no unexpected problems. At least judging from the running sound, the thrust of the two engines All decreased.

The reason why the accelerator needs to be retracted before turning out of the spiral is to prevent the thrust from being too large, which will accelerate the spiral downward momentum of the aircraft. The speed increases too fast, and the aircraft fuselage structure cannot support it.

After pulling back on the throttle, Richard Bayer stepped on the left rudder while slowly pushing the sidestick forward.

Take three steps out of the spiral, retract the accelerator, step on the reverse rudder, and push the steering column forward.

Stepping on the anti-rudder is to stop the aircraft from continuing to rotate, and pushing the control stick forward is to recover from the stall, because in a sense, the spiral is caused by the inconsistent degree of stall on both sides of the wings, so to recover from the spiral, you must first Recovery from stall.

Because of his previous "experience" on the sidestick, Richard Beyer has this in his mind, and when he pushes the sidestick forward, his movements are quite gentle.

Ever since Xu Cang let Richard Beyer completely suppress the sidestick signal from his side, it seems that there has been no problem with the feedback of the control signal. Small angle of attack.

Richard Bayer's recovery procedure is very standard, and, fortunately, there are no unexpected changes in either the throttle or the steering surface, otherwise there will be messy problems at this time, to Richard Beyer is quite tricky.

Under the action of the standard spiral recovery procedure, the aircraft was quickly restrained from the momentum of the spiral, but the nose was still pitched down, and the aircraft was still losing altitude.However, the altitude margin of the aircraft was quite sufficient before, and it is acceptable to lose some altitude.

After confirming the recovery from the spiral, Richard Beyer began to push the throttle forward to increase the thrust, and at the same time, he slowly brought the stick to change the attitude of the aircraft to a level flight state.

This operation is not difficult, at least Richard Bayer can disperse part of his energy to Xu Cang on the right during this period.

When he really noticed Xu Cang's situation, his face suddenly changed.

I saw that Xu Cang's lips were slightly purple, and his face was extremely gloomy, with a faint blackness. This is an obvious symptom of massive blood loss, and if such a situation persists for a long time, the injured will enter a state of shock.

Once you go into shock and cannot get treatment in time, it will be life-threatening.

"Xu Cang, can you hear me?" Richard Bayer immediately yelled at Xu Cang after stabilizing the plane a little, for fear that Xu Cang would fall asleep at this time. If he fell asleep in this state, Most likely sleepless.

Xu Cang drooped his eyelids and glanced at Richard Baier: "I'm not deaf, so I don't need such a loud voice."

"But your complexion is very bad, you must hurry to the ground." Richard Baier was worried: "If this is the case, we will not be able to take the last road."

Xu Cang raised his eyelids, and seemed to relax a bit: "Are you talking about forced landing at sea?"

Richard Baier did not speak, which was acquiesced.

Xu Cang had completed a nighttime forced landing at sea off the coast of Qizhou, and Xu Cang was able to complete such a difficult forced landing.Of course, no one can always be [-]% sure of this kind of thing, and Xu Cang's condition is not good, and he is completely inferior to the energy and spirit he had when he made an emergency landing off the coast of Qizhou. Therefore, the probability of a successful emergency landing is even higher Small.

However, no chance is better than no way out.

If it really comes to a point where there is no way out, then it is not a matter of small probability, but it must be done.

However, with Xu Cang's situation now, let alone whether he can withstand the impact of the forced landing at sea, or the possible erosion of the cold sea water after the forced landing.Even if he survived by luck, in the vast sea, he would have to wait for the rescuers to come, and then he would have to wait for the hospital on the shore. Xu Cang probably wouldn't be able to survive that time.

"Xu Cang." Richard Baier was about to say something, when suddenly, there was the sound of electric current in his ear.

Richard Baier was taken aback, and turned his head to scan the cockpit, wanting to know where the electrical sound came from.

"It seems to come out of the speakers." The captain behind pointed to the speakers on the upper left and right sides of the cockpit, and then looked down at the communication panel: "Is the communication system about to be restored?"

At this time, the aircraft has been relatively far away from the aurora area and the ionizing radiation area. Without strong electromagnetic interference, some other systems related to the electrical system seem to be about to resume work.

However, now in the electrical emergency configuration, the speakers can only emit sound at a fixed low volume, and the crew cannot turn up the volume.

"The communication system has been restored?" Richard Bayer was overjoyed: "Part one, or part two?"

At this time, the plane had deviated far from the scheduled route, and they didn't know which area they were in control now.So, the captain immediately pointed to the second VHF: "Call directly on the emergency frequency."

Richard Bayer quickly switched the transmitter to the second VHF, facing the microphone, and pressed the speaking button: "WN3102, please answer if someone hears it!"

After the words were spoken, there was no response from the speaker, only the occasional two blaring current noises.

"It's useless?" Richard Bayer was taken aback, and immediately called the emergency frequency several times, and the current noise disappeared immediately after that.

"Damn it, what the hell." Richard Baier cursed, put the earphones aside, and then looked at Xu Cang who was already extremely weak: "Shall we continue to fly forward?"

Xu Cang leaned his head on the seat, his gaze moved down and focused on the throttle lever: "Did you close the throttle just now?"

Richard Bayer nodded: "Yes, I was on the throttle at first, but."

"But... the number one engine is accelerating." Xu Cang withdrew his gaze and focused it on the vast starry sky, followed by a long silence.

On his side face, Richard Baier saw a deep solemnity.

"That means that the aircraft's engine control system has a problem similar to that of the flight control computer, and the position of the throttle stick does not correspond to the thrust?" The captain clarified the current situation a little bit, and his voice became more and more desperate. .

Although the sidestick and engine throttle lever seem to be normal now, the lessons learned from the past are vivid. No one knows when there will be problems with the sidestick control under the flight control computer and the throttle adjustment under the engine control system.

Or, all three in the cockpit had a hunch that the glitch hadn't gone away, it was only briefly hidden, and it would come later.

So, in a situation of unforeseen aircraft state control and unforeseen aircraft thrust adjustment, can the aircraft really fall?
"Xu Cang, there seems to be no problem with the side stick and throttle now." Richard Baier said in a low voice: "If there is a problem, or if there is a problem, can you go down?"

Xu Cang tilted his head, his face was very scary, and there was already a little dead silence, he just looked at Richard Bayer silently: "If the flight control surfaces and engine thrust are completely unpredictable, then this aircraft Is the plane still controllable?"

Richard Bayer's lips moved. He didn't know how to answer this question. There is no doubt that the current situation is completely beyond his ability.

The flight control computer and the engine control system have problems one after another, and the plane may not listen to the crew's instructions at all. Can such a plane land?

This seems to be a rhetorical question, but inside it is a definite statement.

It is a necessary prerequisite that the aircraft must be controlled in order to be "controlled" to land.

The captain's face turned pale all of a sudden. If it was just a problem with the response of the flight control surface, he was not so desperate, because in the hands of some extremely skilled pilots, it is possible to rely on a single He landed on the throttle lever, and he believed that Xu Cang was the representative of the so-called extremely skilled.

"Then what to do?" Richard Bayer asked this question again in shame, no matter when, he could only ask this question.

Can a plane that has completely lost control really fall?

If it was possible, it must have come from Xu Cang, but in Xu Cang's current state, he might not even be able to lift his hand.

Xu Cang's Adam's apple moved, and he suddenly turned to Richard Baier: "Let's go to Japan!"

"Japan!?" The captain was taken aback: "Why go to Japan? From the current position, going to China should be a little closer."

Xu Cang shook his head, and said in a weak but firm voice, "Let's go to Japan!"

Richard Bayer opened his mouth, and he suddenly realized a possibility: "Xu Cang, do you think this plane is going to crash? Do you think we can't survive?"

"This plane is no longer safe. I will try to bring it down, but I am not sure." Xu Cang's eyes were extremely deep: "If it is going to crash in the end, then it shouldn't crash in my country. It never Wherever it takes off, it will naturally go back, and Japan is where it should go."

Both Richard Bayer and the captain were stunned by Xu Cang's words.

It is obvious that this plane is not safe, but if this sentence comes from Xu Cang's mouth, it will have a different meaning.

In Xu Cang's words, he had already prepared for the worst.

A plane crash is not a possibility with a very small probability, but something that is very likely to happen, and Xu Cang does not want this kind of thing to happen in his own country.

It is true that it will take longer to return to Japan, but Xu Cang will still choose this route.

"You can't do this!" The captain let out a piercing roar after a short silence, the sharp and painful voice almost resounded throughout the cabin: "If you fly to Japan, your condition will not be able to survive the landing !"

Now Xu Cang only has half his life, and if he takes a longer time to return to Japan, he will probably have only one breath left during the approach. How can he land in such a state?
"Then do it yourself!" Xu Cang narrowed his eyes, like a tiger licking its wounds.

The captain choked for breath, and he held his head: "No, no, no, we can't fall, we can't fall."

Seeing the captain who was in despair and fear, Richard Baier comforted him in a low voice: "At least the side stick and throttle are all right now, and maybe the failure of the flight control computer and engine control system will not appear in the future. We You can fall by yourself."

If there is no problem with the sidestick and throttle, with the ability of Richard Baier, he is still very sure to complete the landing despite the huge failure of the electrical system.

But will the situation really be as Richard Baier said?

"Impossible, we all know that those faults have not disappeared at all, how could they disappear?" The captain seemed to go crazy in extreme fear, he leaned his upper body forward, and pushed his right hand towards a pair of throttle levers.

Richard Byer was caught off guard, and the throttle lever was pushed forward a little.

In such cases, the thrust should be slightly increased.

However, in fact, the plane's nose suddenly turned to the left, so scared that Richard Bayer quickly pressed against the right rudder to eliminate the nose drift.Moreover, he didn't dare to move the throttle lever anymore, for fear that something might go wrong again.

"I'll just say, I'll just say the fault hasn't gone away at all!" the captain roared.

The reason why there is a sudden leftward bias is that the thrust of the No. [-] engine is greater than that of the No. [-] engine.However, under the position of the throttle lever, both sides are the same. Reasonably, the thrust of the engines on both sides should be roughly the same.

Once again, the thrust of the engines on both sides is inconsistent, which directly proves that there is still a problem with the engine control system.

However, the problem seems to be intermittent.

Similarly, the failure of the flight control computer should also be intermittent.

Intermittent and continuous are actually not very meaningful in essence. As long as it goes out once on the fifth side, the state of the aircraft will have an extremely terrifying deviation, and it cannot be repaired at all later.Moreover, with the frequency of failures of the flight control computer and engine control system, there must be problems during the final approach.

Or, to be precise, in the current situation, can they really fly to the fifth edge?

"Without him, we can't live at all!" The captain stood up directly from the observer's seat. He put one hand on the top of Xu Cang's seat, with a fierce expression on his face, and approached Xu Cang: "You Can’t go to Japan, go to Japan, we can’t survive!”

"If you can't survive, it's just your own fault." Xu Cang said coldly.

"No, no, you can't do this." The captain's eyes were bloodshot: "You are a god, you must have a way, you can fall even if the wings are broken, you are omnipotent, you can clearly Save us all!"

Xu Cang turned his head, his eyes were extremely firm: "Then go to Japan!"

The captain immediately became irritable: "Go to Japan, go to Japan, but you don't even have that damn navigation, how do you go to Japan, how do we go to Japan?"

They all know that Japan is roughly in the north now, but they don't know the specific direction.In view of the existence of some special countries, they cannot go north indiscriminately.

Xu Cang kept saying that he was going to Japan, but he didn't know how to go to Japan at all!
"I'll know soon." Xu Cang withdrew his gaze and murmured softly.

The captain was startled: "What did you say, what do you know?"

A little light reflected in Xu Cang's eyes: "I know. How to get to Japan!"

Almost at the moment when Xu Cang's voice fell, a somewhat vague English with a slight accent came out from the speaker that originally only had the sound of babbling current.
“This is China Air Force”
