Return to 2000: Captain of the Great Powers

Chapter 92 The Way of Genius!Descend to the Tianshan Mountains! (Please subscribe!)
The cockpit of Blue Sky Flight 9211 fell into an eerie calm. After a brief shock, the captain suddenly asked with a straight face: "Do you really know how to fly?"

Although the captain still had that cold appearance, even Xia Shuyue, who was sitting in the back, could feel his stern nature.In the final analysis, the only thing that prevents the captain from bowing his head to Xu Cang is his little self-esteem as the captain.

Xu Cang did not answer immediately, but looked up at the APU exhaust temperature gauge.However, after waiting for a while for the exhaust temperature of the APU to stabilize in a reasonable range, the indicator light of the APU generator switch did not light up.

Xu Cang's eyebrows twitched, and he looked a little surprised: "Is the whole circuit burned out?"

"Huh?" Startled by Xu Cang's words, the captain also glanced at the APU's exhaust temperature gauge and indicator light, with a hint of confusion on his face: "Is it starting, or not?"

If the engine fails to start before, the exhaust temperature of the APU will directly return to zero, which is easy to distinguish.However, judging from the current exhaust temperature value, the APU seems to be started, but the indicator light of the generator is not on, how to distinguish it.

"Can you hear the sound of an extra engine running?" Xu Cang turned his head and asked Xia Shuyue.

Xia Shuyue was taken aback, and listened carefully, but shook her head: "Brother, I can't hear you."

"Yes, the APU is at the tail of the plane, and the sound is very small, and it's normal if you can't hear it." The APU is the auxiliary power unit, which is essentially a small engine, but the power is much smaller than the normal engine. The rumbling sound, but it certainly can't be compared with the engine hanging on the wing.

Of course, Xu Cang did not expect that the power circuit was damaged to such an extent that even many indicator lights did not work.

The captain couldn't help asking: "Then what should we do now?"

Don't look at the captain wishing to swallow Xu Cangsheng alive before, but at this moment, it's just a distaste for his words.

"I'll try it first, and you watch the plane." Xu Cang bent his head and thought for a while, but he still didn't care about the APU generator indicator light. The doors are all connected.

Under normal circumstances, most of the electrical equipment can resume operation after the new power supply is connected, but after Xu Cang switched on the two switches, no reaction could be felt in the cockpit.

Now Xu Cang's face couldn't help showing a little wave, and he tried to connect again, but there was still no change.

"The APU didn't start well, or is there something wrong with the circuit?" The captain became anxious again, how to start the engine without a new power supply?
"I don't know, I can't see any data now, and I can't be sure. However, no one can say for sure about the situation in the cockpit now. In case the electricity has been connected, it just doesn't show up. No matter what, the engine still needs to Trying to restart. Don’t lower the altitude anymore, just keep it at 6000 meters, and it may be dangerous to lower the altitude.”

The captain was taken aback: "What's the danger?"

"The terrain is dangerous!" Xu Cang took a deep breath. He was actually somewhat prepared for the current situation, but he still felt a little nervous when he encountered it.Even the power of the battery used as an emergency power supply cannot be connected, and it is not impossible that the APU power cannot be connected.

"Now that it's an emergency, I'll just do it from memory. I'll do the engine failure or shutdown checklist first."

The captain is now controlling the single-engine aircraft, and Xia Shuyue cannot be expected to read the checklist. To be honest, the Boeing checklist is for ordinary people to read, and they may not be able to understand it, even if they know every word.

The engine start-up inspection cannot be done directly. The engine failure or shutdown checklist must be completed first. This is a procedural requirement, and the order cannot be messed up.

"The aircraft has no abnormal body vibration and no engine separation. The autothrottle is disconnected!" Xu Cang signaled the captain to press the autothrottle disconnection button on the top of the thrust handle to verify that the autothrottle was disconnected.

The captain pressed several times to ensure that the autothrottle was disconnected.

"Thrust handle, No. [-] engine, it is confirmed that it has been turned off!" Xu Cang pushed the captain's right hand on the accelerator with his left hand: "I will protect the second engine, you can cut the first one."

The captain took a glance that he was indeed holding the throttle of the No. [-] engine. This could not be a mistake. After confirming that it was correct, he moved the throttle of the No. [-] engine to the idle position.

"No. [-] engine is verified to be at idle thrust, No. [-] engine starter handle is confirmed to be cut off! You protect the second engine!"

"Ah? Oh!" The captain still focused most of his energy on controlling the plane, and completed most of the movements under Xu Cang's guidance.He glanced at the position of the engine starter handle, and put his hand on the number two engine starter handle.

Xu Cang saw that the captain had secured the No. [-] engine starter handle, so he grabbed the No. [-] engine starter handle by himself: "The No. [-] engine is verified to be cut off."

As soon as the words fell, Xu Cang cut off the starter handle of the No. [-] engine, which also completed the shutdown process of an engine.

Afterwards, Xu Cang turned off the switch of the left component, which will make the components that work when the flaps are closed in flight be adjusted to high flow.

According to the checklist, you need to start the APU later, and then connect the APU generator switch.However, this step has already been done before, and the action of connecting the electricity has also been completed. As for whether the electricity has been connected, only God knows.

Then, Xu Cang carried out some finishing work, such as balancing the fuel, and turning the mode selector of the transponder to the TA position, in order to prevent the occurrence of climb commands exceeding the performance capability of a single engine.Now, though, the answering machine doesn't work at all, and it really doesn't make any difference whether it turns on or off.

Thereafter verify that the isolation valves are in the AUTO position to ensure that both wings are powered when the wings are anti-iced.In the current state, the wing anti-icing is always turned off, and Xu Cang dare not use the wing anti-icing at this time.

Because if there is insufficient bleed air, opening the wing anti-ice will have a slight possibility of causing the engine to stall, especially at high altitudes.

Of course, 6000 meters is definitely not a high altitude, and basically there will be no problem of turning off the car caused by opening the wings to prevent ice.But Boeing's plane is really bad. In the case of a single engine and it may not be able to restart, Xu Cang dare not take risks.

The next step is to go to the Engine Air Start Checklist!

Just when Xu Cang was about to continue with the checklist for engine air start, he suddenly felt something. He picked up his mobile phone, turned on the flashlight on it, and took a photo outside the windshield.

The light of the flashlight finds the oncoming raindrops and reflects the bright light, making it look like an airplane is traveling through a time-space tunnel.

"The rain has become smaller?" Xu Cang murmured.

Just looking at the density of the rainwater, it is estimated that there is light rain to moderate rain outside, which is much smaller than the scene where the sky was cracked and poured down.

The captain's eyes lit up when he heard that the rain had subsided, which indicated that they were gradually moving away from the dangerous weather.Moreover, less rain will have less impact on the engine, which is completely good news.

However, Xu Cang couldn't be happy at all.

In the Urumqi regional control room, the supervisor on duty walked back and forth an unknown number of times.However, no matter how he walked, his eyes were firmly locked on the radar screen, always praying for when the radar signal of Lantian 9211 would suddenly jump out again.

However, as he paced for a long time, the little hope only became more and more elusive, and a wave of irritability slowly rose from the duty teacher.

It's been too long, it's been too long since Blue Sky 9211 lost contact.Every minute that passes now, the chances of the crew and passengers surviving decrease.

Suddenly, his assistant trotted over and reported to the director in a low voice: "We checked our radar just now, and there is no problem!"

Even though he was prepared in his heart, the director almost rolled his eyes and fainted when he heard the news.Just now, he felt a little fluke in his heart, what if there is a problem not with the crew, but with his own radar?

Although the assistant felt that the director was deceiving himself when he heard the director's conjecture, he still followed the director's wishes and asked the technical department to do a simple inspection. The result was that the equipment was normal and there was no problem.

"Director, what should we do now?" the assistant asked casually.

This sentence directly ignited the long-suppressed anger of the supervisor on duty, and he became furious in an instant: "What should I do? How do I know what to do?"

"Director, can we contact the military and borrow their radar?" At this moment, a weak voice suddenly came out.

According to the director's reputation, it was the controller who was in charge of communicating with Lantian 9211 before.

The director frowned: "What did you just say?"

"I'm talking about contacting the military and asking them to use military radar to scan the airspace where Lantian 9211 lost contact. Their radar doesn't need a transponder to respond. If Lantian 9211 is still in the sky, they should be able to find it." The controller said anxiously .

To be honest, he didn't know if this method was feasible.But logically speaking, it should be possible. Although there are many kinds of military radars, most of them are radars that rely on electromagnetic wave reflection to determine the position of the aircraft. The answering machine is working.

Of course, the premise of all this is that Blue Sky 9211 is still flying in the sky.If you can't even see the military radar, then this matter will be piercing the sky.

The supervisor on duty was stunned for five or six seconds, and then his face showed ecstasy as if juggling, and he slapped the controller on the shoulder: "Your boy usually looks silly, you have a lot of tricks, it is feasible, it is absolutely feasible !"

The supervisor on duty had had enough of this meaningless long waiting, suffering like Ling Chi, and he desperately wanted to do something.After thinking for a while, he felt that the idea of ​​borrowing military radar proposed by the controller was feasible and not small.

But the assistant was a little worried: "Director, our civil aviation has become independent from the air force. Is this easy to handle?"

The supervisor on duty did not take it seriously: "If there is anything difficult to handle, the military and civilian families are close, so there is no need to see outsiders."

The assistant really can't laugh or cry, his boss doesn't treat himself as an outsider.

With the direction, the supervisor on duty didn't want to stay here anymore, and went to find someone to contact the military non-stop.

At this moment, in the cockpit, Xu Cang began to start the engine in the air, still doing it from memory as always.

According to the altitude and speed of the aircraft, Xu Cang decided to start with cross-bleed air, which was approved by the captain.

After verifying that the thrust handle of the No. 2 engine was turned off, and the start handle was cut off, Xu Cang was ready to start, but before the action, he said in advance: "There is still rain outside, as long as the N[-] rises steadily and the EGT does not exceed the limit, you can start the engine. Do not abort the crank."

The reason why Xu Cang specifically explained this problem is that after the engine starter handle is lifted to the idle position, the EGT is required to respond within 30 seconds, otherwise the start will be interrupted.

However, at high altitude and heavy precipitation, the ascent of EGT can be very slow, which is not suitable for this limitation.Xu Cang said in advance that it was to prevent the captain from aborting the start by mistake.

"I know." The captain responded, showing that he knew it well.

In fact, Xu Cang said that this has no special effect. Anyway, EGT can't see it now, and there is no place for reference.

"Okay, then I'll start." With that said, Xu Cang turned the engine start switch to the ground position after confirming that the left component was off and the pipeline pressure exceeded 20PSI, and then began to wait.

With the rotation of the starter, the N2 rotor is driven to start running.Under normal circumstances, you have to wait until the N2 speed exceeds 11%, but there is no display on the DU at this moment, so Xu Cang waited for a while, guessing that the N2 speed is enough, and then shouted: "No. [-] engine slows down!"

The captain also allocated part of his energy to pay attention to the starting process. When Xu Cang called out to lift the starting handle, he probably felt that the N2 speed was enough, and without hesitation, he lifted the No. [-] engine starting handle to the idle stop.

Then comes the most important moment.

The two began to count silently in their hearts. Normally, both of them should have read the EGT index, but now there is no EGT data, so they can only hold their breath and listen to the movement of the engine outside.

Xu Cang also patted Xia Shuyue behind: "You also stop carefully, is there any sound of the engine restarting!"

This girl has very good ears, so she has to make full use of them.

If you can hear the sound of the engine restarting, and then confirm it with the status of the aircraft, you can basically determine the condition of the engine.

I don't know if it was because of the influence of the captain and Xu Cang in front that Xia Shuyue also became nervous, her heart was beating so loudly that she couldn't distinguish the movement outside.

After waiting for a full minute, none of the three heard the sound of the No. 1 engine restarting, and they immediately showed disappointment.

"Is the plane still leaning to the left?" Xu Cang asked.

The captain let go of the disc slightly, and as expected, the plane began to veer to the left spontaneously.Now it was true that the No. [-] engine did not start successfully, and none of the three had auditory hallucinations.

The captain cursed: "The igniter is still useless!"

Xu Cang sighed, and asked the captain to cut off the No. [-] engine start handle, and then cut off the engine start switch: "Try one last time!"

However, all of this is just Xu Cang's unwillingness to give up.After trying again, the result was the same, and he had to accept that the aircraft's electrical system was completely broken.

Even Xia Shuyue, she could feel the disappointment that Xu Cang showed after the two activations failed.

"Brother, what shall we do next?" Although the captain is also here, Xia Shuyue instinctively regards Xu Cang as the backbone.In fact, even the captain looked at Xu Cang.

Even if he was a little upset, a little embarrassed, and a little unreasonable, he instinctively felt that Xu Cang could bring him to the ground safely.

"At the beginning, if I can start the No. 040 engine, I plan to fly heading 040." Xu Cang said softly: "The weather in this area is distributed from north to south, and flying heading [-] can be completely flown out. At that time, you can see the ground." situation."

The captain was taken aback: "Heading 040? Isn't that flying in the northeast direction? Isn't this the opposite direction to our destination? Besides, the water compass can't be used now, how do you determine the heading of 040?"

"It can be calculated by the slope. Although there is a slight change, we are still maintaining the initial heading of 300. Then we can use the timing and slope indicator to form a heading of 040. It doesn't need to be too accurate, as long as it is almost the same. "Xu Cang said: "As for flying to the northeast, because we need to find a sufficiently obvious landmark to determine our position."

The captain's mind was running crazily, and he suddenly remembered a place that fit Xu Cang's words, and he said in a daze, "You mean Pengze Lake?"

Pengze Lake, the largest freshwater lake in China, covers an area of ​​nearly [-] square kilometers, and can be easily distinguished even at high altitude.

"That's right! It's Pengze Lake!" Xu Cang's pupils shrank suddenly: "P37, the starting position where we deviated from the route, is not far from Pengze Lake. Pengze Lake."

Xia Shuyue couldn't help but wonder: "But even if we reach Pengze Lake, how should we fly?"

"That's right!" The captain didn't understand Xu Cang's meaning: "Pengze Lake is not an airport, so what's the use of flying to Pengze Lake?"

The captain still said that he was conservative. There is no airport in a large area around Pengze Lake. What is the point of finding Pengze Lake?
"Of course it works!" Xu Cang breathed a sigh of relief: "Wushi Airport and Pengze Lake happen to be in the same dimension, and they are exactly the same! As long as we fly over Pengze Lake, rely on the sun to distinguish the east-west direction, and then head towards the west Fly over. Now the high-altitude wind is basically in the east-west direction, and it will not have a big impact on our heading. As long as we fly to the west, we will definitely be able to fly to Wushi Airport, and there will be no error!"

hiss!
As soon as Xu Cang finished the call, the captain only felt goosebumps all over his body, and he looked at Xu Cang like he was looking at a monster.Not long ago, Xu Cang said that he could solve the navigation problem, but he still didn't believe it, but now he just feels that Xu Cang is not human at all.

Latitude, high-altitude wind, and reference object recognition were all considered by him, and they were combined to form a practical and reliable plan. This plan was so perfect that the captain only felt chills.

Such a person is terrible, his existence is to transcend common sense and rationality, and he just wants to prove that people are indeed different.

Xia Shuyue, who was sitting in the back, had a bright light in her eyes. At this moment, Xu Cang seemed to be enveloped in the holy light.

"Sure enough, all of this is the arrangement of fate!" Xia Shuyue shouted in her heart, she felt that God had pointed out the direction for her future.

"Then let's go!" The captain was almost too excited: "Fly to Pengze Lake now!"

"No!" Xu Cang shook his head, "It's too far! It takes about two and a half hours to fly from here to Pengze Lake and then to Wushi Airport. The fuel is sufficient, but the engine is not working!"

When the flight took off, due to the weather in the northwest region, there was a lot of fuel released.However, the problem is not the amount of fuel, it's that they only have one engine.

The captain was anxious: "One engine can fly over!"

Xu Cang stared at the captain coldly: "If you let a single-engine passenger plane fly for two and a half hours, do you think the rule that the single-engine passenger plane must land within one hour after the single-engine flight is made randomly? Besides, Peng Zehu went to Wushi A large part of the distance between the airports is full of Gobi desert, and we don’t have any options for alternate landing. If the two engines are normal, I will choose this way, but not now!”

In the final analysis, the current condition of the plane is too bad.With a single engine running, the power system was almost completely destroyed. Even Xu Cang did not have the confidence to sustain such a plane for two and a half hours.

"This won't work, and that won't work, so what shall we do?" As soon as Xu Cang saw some hope, he ruthlessly rejected it, and the captain couldn't help feeling a little anxious.

"Then we'll descend!" Xu Cang narrowed his eyes: "We'll find life below!"

"Below?" The captain was taken aback: "It's still covered by dark clouds, what can you see below? And, didn't you just say to pay attention to terrain threats?"

"The light is really bad now. Some things can't be seen, but some things can be seen." Xu Cang took a deep breath, and it could be seen that he was also very nervous at the moment: "The altitude of 100 meters should be enough to ensure enough topographic margin."

The captain complained: "Should? Can you use the word should for this kind of thing?"

Xu Cang glanced at the captain, he directly held the steering wheel with his right hand, pushed the captain's hand away from the throttle lever with his left hand, slightly reduced the thrust, and then began to lower the ejector rod.

"If my calculations are not wrong, the highest area below us should be Bogda Mountain. The highest peak of Bogda Mountain is 500 meters, leaving a margin of 600 meters is enough." Xu Cang said calmly, but His right hand holding the steering wheel and constantly opening and closing betrayed his true state of mind.

The captain frowned: "Bogda Mountain, isn't this mountain?"

Suddenly, the captain's eyes widened, as if he understood what Xu Cang was going to do!

The altitude of the plane was already very close to 100 meters. As the altitude dropped, the clouds became thinner and thinner, but the captain became more and more flustered: "Xu Cang, if we are still in the clouds at an altitude of 100 meters Where, can we still go down?"

Xu Cang pursed his lips without saying a word, a trace of determination flashed across his face.

At the moment when Xu Cang finished speaking, Xu Cang slammed forward, and the plane seemed to break through the shackles and rush out of the clouds when it was about to reach 100 meters.

In an instant, the darkness dissipated, and the light came!Between heaven and earth suddenly enlightened!A little light scattered from the gaps in the clouds, reflecting the vast land in front of everyone's eyes.

On the dark land, there is a pitch-black mountain range winding away, as if it has no end.

It divides the northwest land into two like a moat.
It is like a descended dragon lying on the earth,
it exists from time immemorial

It is Tianshan!
