Return to 2000: Captain of the Great Powers

Chapter 188 I am the one who saved you! (Please subscribe!)
In the cockpit, as the captain cut off the fuel control switch, the No. [-] engine of the plane was quickly turned off, and the noisy engine running sound around was also quieter.

"Check the leveling altitude where one engine doesn't work." The captain didn't start to descend immediately.He was unable to perform a conventional descent due to unreliable airspeed.Just as ascending and cruising can only be controlled according to the attitude and thrust listed in the flight chart, if it is necessary to descend, the captain can only follow certain specific settings, which are reflected in the power settings, that is, to stabilize at idle Thrust, while attitude needs to be recalculated based on the altitude and weight of the aircraft.

At idle thrust, as shown in the graph, the airplane will produce a descent rate of [-] feet per minute at altitudes above [-] feet.This is a rather exaggerated value, so the captain must first understand how much altitude he can maintain when one engine is not working, and promptly raise new altitude requirements with the control.

Although they have declared a state of emergency and gained great priority, it does not mean that there is only one plane in the surrounding airspace. They can ignore the possibility of all air traffic conflicts in a state of emergency and do whatever they want.

"I know this, Captain!" As if he had finally discovered his own value, the co-pilot said immediately, and finally became a little excited, instead of the previous state of doubting himself.

Hearing this, the captain looked at the excited look of the co-pilot, probably not lying, and it finally worked.So, the captain threw the checklist to the co-pilot immediately, and said, "Hurry up!"

The co-pilot nodded fiercely, caught the checklist, and flipped back quickly, his movements were completely different from the previous flight charts for finding unreliable airspeeds, full of confidence.

It seemed that it really happened to hit the co-pilot's only knowledge point.

It has to be said that the co-pilot's performance exceeded the captain's expectations.After about 20 seconds, the co-pilot let out a snort, and the captain turned his head and glanced at the title of the page opened by the co-pilot. It was the descent/levelling altitude with one engine not working.

"It's okay, it's okay!" The captain breathed a sigh of relief just now. The performance of the co-pilot in front of him is really outrageous. If he can't even find the leveling altitude when one engine is not working, it will not be the end. Distract him from looking for it himself?

Just thinking about this possibility made the captain feel exhausted.

"The altitude is 75 feet, and the total weight is [-] pounds!" The co-pilot muttered, and soon found the corresponding data: "The maximum altitude can be maintained at [-] feet."

"Okay!" The captain did not verify what the co-pilot said. This is not much different from the altitude of [-] feet he estimated, so there should be no problem.

Since there is no problem with the target altitude of [-] feet, it is enough to set it to [-] feet according to the specified state.

However, even though it all seemed to be going smoothly, the captain actually had a little worry in his heart, the most serious of which was the unknown substance outside the plane.

Do those things exist at a certain level, or do they become denser as they go down?If the latter, will these things have any other effects on the aircraft?Are these things the cause of the series of problems the plane has had so far?
Just when the captain was in a daze for a short time, he suddenly heard a noisy movement outside.The co-pilot was startled, glanced at the cockpit door, and turned on the monitor probe knob on the center console.

Soon, an image appeared on a small screen on the center console. It was a picture of the front cabin workshop from a side angle. In it, there were two men beside the purser, who were rushing to Xu Cang and Leo in the front cabin workshop.

Since the picture was in black and white, the co-pilot made a little distinction and recognized the identity of one of the men. He pointed to Leo on the monitor and asked the captain: "Isn't this the Airbus executive the company said?"

That's right, as the chief financial officer of Airbus headquarters, Leo's treatment is naturally different.Although he only contacted his friend in British Airways privately, his friend promoted him to VIP directly because of his status as a senior executive at Airbus headquarters, and at the same time notified the flight crew through the channels of British Airways personnel.

This treatment is really quite high standard!

"However, who is this person?" The co-pilot pointed to Xu Cang beside Leo, apparently he didn't know Xu Cang's identity.This is not surprising. As members of EASA, which has the most mature civil aviation system in the world, it is normal for them not to care about the situation in the CAAC area.

Moreover, seeing that Leo and Xu Cang had some verbal conflicts with the purser, the co-pilot was even more puzzled.However, since he knew Leo's identity in advance, even though the co-pilot could feel that the atmosphere in the front cabin was not right, he still didn't express anything special.

However, compared to the ignorant co-pilot, this captain is different, he knows who Xu Cang is!That's right, the captain of British Airways not only knows Xu Cang, but also knows what Xu Cang has done recently.

Although the cockpit door is very strong, its sound insulation is actually just that.At least in the cockpit, the captain and co-pilot could hear Xu Cang's voice relatively clearly.However, because Xu Cang spoke Chinese, the co-pilot didn't understand what Xu Cang was saying.However, the captain is different, he understands Chinese.

Although he didn't know why, he could feel that Xu Cang was very eager to get into the cockpit.Moreover, from Xu Cang's words he heard, Xu Cang seemed to have noticed something very terrible.

"What's the matter?" The captain was in a daze for a moment.

Xu Cang is very young, so young that at this age he has little right to speak in the civil aviation circle.But Xu Cang is different, he has dealt with many major flight accidents, and his ability can no longer be inferred from his age alone in terms of aircraft technology.

If there is something that makes Xu Cang feel fear, then he has reason and should feel this way.He asked himself if he could do better than Xu Cang in the accident that Xu Cang encountered before.

During the short period when the captain was hesitant, the co-pilot next to him saw that the plane had not descended for a long time, and he couldn't help feeling suspicious: "Captain, let's get off."

Before he finished speaking, a faint blue light suddenly flashed in the corner of the co-pilot's eyes, like a ghost.The co-pilot's Hun'er seemed to be hooked, and subconsciously looked in the direction of the nose of the outside world.

Just looking at it, I suddenly felt a coolness flooding my whole body, and I saw a blue flame floating slowly on the tip of the wiper outside the nose of the plane.

The flame seemed to grow without roots, and it stood quietly on the tip of the wiper. It always gave people a strange feeling to see such a scene above the [-]-meter altitude.

Following the leaping flames that appeared out of thin air, the captain was finally attracted to lose his attention.The first moment he saw the flame, he just froze for a moment, and then popped out a word: "Sant'Erasmo!"

This term fell into the ears of the co-pilot, but it just made the co-pilot confused.However, at this moment, due to the power of the three engines, the plane could not maintain a level flight and cruise at an altitude of more than [-] feet. posture to enter the descending state.

With the plane's reaction like this, the captain just woke up from his trance. They are not motivated enough now, even if they don't want to descend, they have to descend.

So, the captain immediately pushed down the stick slightly, the movement was very slight.If you don't do this, the speed of the plane will probably be lost.

However, the specific attitude to push the aircraft to depends on how it is marked on the flight chart.

"You turn to the flight chart of the unreliable airspeed ahead, and then give me the checklist!" The captain said quickly, and then planned to put all the throttle back to the idle vehicle.

In the descent of unreliable airspeed, the throttle is the default idle thrust, and it is not the captain himself who is willing to choose such a rough descent method.

The co-pilot couldn't understand the flight charts of unreliable airspeed, but with previous experience, it was still very fast to find out the charts.

However, just as the co-pilot was about to turn back, he heard a heavy blow to the cockpit door, followed by a man's roar: "Don't fucking descend, you're looking for death!"

After the captain heard this sentence, his right hand, which was about to close the throttle, suddenly paused in the air.The co-pilot next to him quickly turned around and looked in the direction of the cockpit door, complaining, "What the hell are you doing up front?"

However, the co-pilot soon noticed that the captain's right hand went straight back after a moment of bluntness until it landed on the switch knob of the cockpit door locking system.

"Captain!?" The co-pilot hadn't figured out what was going on, but saw the captain manually unlock the cockpit door!

The co-pilot's mind was blank, he never expected that the captain would open the cockpit door at this time.

However, with the unlocking of the cockpit door lock, the door was pulled open from the outside, and the co-pilot saw a young figure, it was Xu Cang.

In Xu Cang's field of vision, the fuel control switch of the No. 737 engine has been disconnected.This switch is somewhat similar to the engine starter handle on the [-], of course, it is only similar and not exactly the same.

Xu Cang wasn't worried that the crew would turn off the throttle, and if it was turned off, it would just be added again.But if the fuel control switch is closed, it means that an engine is actually stalled, and it must be re-ignited to make it work.

However, in the environment surrounded by volcanic ash, the possibility of a successful air start is basically eliminated, so Xu Cang was extremely worried that the crew would shut down the engine.

"What did you just say? We can't descend, why can't we descend?" What Xu Cang didn't expect was that the captain sitting on the left seat could speak fluent Chinese.

Xu Cang stepped into the cockpit one step at a time. It would be best if the captain could understand Chinese.It's not that Xu Cang doesn't know English, he can understand materials and books in English, but it's more troublesome for him to express it in spoken language.

"Where do you think we are?" Xu Cang asked back. After entering the cockpit, he quickly scanned everything in the cockpit in order to understand the situation as soon as possible.

At this time, the male flight attendant who wanted to rush up to lock Xu Cang suddenly heard Xu Cang communicate with the captain in a language he didn't understand, and was stunned on the spot to see if the flight attendant didn't know what to do.

Fortunately, the flight attendant was very clever, and immediately shook his head towards the male flight attendant, signaling him not to touch Xu Cang, and then pointed to the entrance of the front cabin work room, asking him to guard the entrance and close the curtain at the same time.

The captain didn't quite understand Xu Cang's meaning: "What exactly are you trying to say?"

While the captain was talking, he saw Airbus Chief Financial Officer Leo following Xu Cang through the cabin door.He knew Leo, and it was for this reason that the captain was willing to give Xu Cang some extra patience at this critical moment.

"There was no St. Elmo's fire just now, right?" Xu Cang already understood the situation of the plane in just one sentence: "Haven't you thought about what's below us?"

"St. Elmo's Fire?" The captain was stunned, and then his mind turned, thinking of a possibility: "You mean these things outside are ice crystals? No, there is no lightning area observed outside."

When a plane encounters severe ice crystals, it does have the potential to start St. Elmo's fire.This kind of flame is actually not a real flame, but a luminescent corona discharge phenomenon, which is a group of plasma with relatively low temperature.

In some weather conditions, such as a thunderstorm environment, the huge potential difference in the air directly exceeds the threshold of the air dielectric, thereby breaking down the air and making the air conductive.And St. Elmo's fire is the strong light released during the conduction of air.

Since St. Elmo's fire often occurs at sharp objects in a thunderstorm environment, during ancient voyages, the crew would occasionally observe this phenomenon at the top of the mast in thunderstorm weather.

And St. Elmo was named after a third-century Italian saint who was rumored to be the saint who protected sailors.Therefore, after seeing this phenomenon, the sailors thought it was the apparition of St. Elmo, so it was called St. Elmo's fire.

The captain recalled that when he observed the weather information on the navigation page just now, there was indeed no thunderstorm phenomenon.

"Then do you think that only thunderstorm weather can accumulate enough charge?" Xu Cang said coldly.

One of the conditions for the formation of St. Elmo's Fire is that the air is ionized and broken down, and the basic condition for this to happen is that a large amount of electric charge is accumulated in the air.The thunderstorm weather just meets this condition, so St. Elmo's fire mostly occurs in thunderstorm weather.

However, that doesn't mean that thunderstorms are the only conditions necessary for St. Elmo's Fire.

The captain reacted quickly, and under Xu Cang's instruction, a flash of inspiration suddenly flashed in his mind.He quickly turned on the landing lights again, and the unknown black substance speeding past outside was no longer mysterious in his eyes.

"Fire and ash!" The captain spat out these words tremblingly.

It was volcanic ash!
The volcanic ash itself is indeed not charged, but the volcanic ash will accumulate a large amount of electric charge under the violent friction with the fuselage.Therefore, once the aircraft strays into the area of ​​volcanic ash, it is easy to form St. Elmo's fire on the protruding part of the fuselage.

For example, the fairing of the engine, such as the position of the nose!

The co-pilot couldn't understand Chinese, but from the captain's expression, he probably knew that the young man who entered the cockpit seemed to have said something serious.

The co-pilot inevitably had doubts: "Captain, what's wrong?"

"No, no! How could it be volcanic ash? If the route would be covered by volcanic ash, the company dispatcher would have informed us in advance." The captain said in disbelief.

Even though the bloody reality is showing the tragic result of volcanic ash, the captain is still unwilling to believe it, because this kind of thing is too dreamy.

That's volcanic ash!Now they are above [-] meters, and they can encounter volcanic ash, which means that the volcano that caused the eruption of volcanic ash is a giant volcano.

The volcanic ash produced by a volcanic eruption of this scale will have a huge impact on the aircraft. Can British Airways dispatch ignore such a major matter?
"I think instead of caring about why your own dispatcher ignores such a big thing, you might as well think about whether the plane can land or not?"

As soon as this remark came out, the captain was stunned for a moment, and after thinking for a while, he suddenly felt cold sweat running down his back.

Something is wrong!There is a huge problem with his decision-making!
You must know that even in the large-scale eruption of a giant volcano, it is relatively rare for the volcanic ash to reach more than [-] meters.Then, in the face of this fact, it is very reasonable to infer that they are not actually in the volcanic ash, but the upper edge of the volcanic ash, which means that they have a high probability of not actually entering the volcanic ash. Volcanic ash is directly below them.

In this way, the landing of the plane is not to survive, but to enter the center of the volcanic ash thoroughly, which is a real suicide attempt!

Xu Cang looked at the distorted expression of the captain: "Understood? You should let the plane surge, then try to maintain the altitude and return!"

"Isn't the engine about to be scrapped?" Behind Xu Cang, Leo suddenly said.

He is not a particularly professional person, but he still knows some aircraft knowledge, especially what it means to understand engine surge.

"That is a loss that must be accepted in order to seek vitality!" Xu Cang said coldly: "The engine should be kept at a high thrust, let it surge until it is scrapped! Well, now that the engine is cut off, you should also snuffed out his life."

Hearing what Xu Cang said, the captain thought again, feeling ashamed and ashamed.He cut off the engine too recklessly, and directly ruined a shortcut that could return to the voyage relatively easily.

You know, once you enter the volcanic ash area, it is basically impossible to restart the engine.

The captain suddenly turned to Xu Cang, and looked at Xu Cang with an extremely expectant look: "What should we do now?"

Xu Cang didn't answer the captain's question directly, but pointed to the co-pilot: "If possible, can you ask him to move?"

The co-pilot was stunned, he couldn't understand what Xu Cang was talking to the captain, but seeing Xu Cang's actions, he felt that the conversation between the two seemed to involve him.

The captain hesitated for a moment, turned his gaze to the co-pilot, switched to English, and said, "You go to the first-class cabin!"

"Ah?" The co-pilot obviously didn't understand the situation: "Captain, what am I doing in the first class?"

"Give him a seat!" The captain pointed to Xu Cang, and continued: "By the way, don't go to the first-class cabin, go to the second floor and call Tom over."

They had wanted to call the second captain over a long time ago, but a series of incidents interrupted them, so they didn't take any action.

"He!?" The co-pilot looked at Xu Cang incredulously: "I don't even know who he is, is he a pilot? Even if he is a pilot, how good is his flying skills as an Asian? Captain, you Doing so is violating the company's rules!"

A blue vein popped up on the captain's forehead: "He's very powerful, very powerful, hurry up and get down!"

"Captain, it's impossible for me to hand over my position to someone with unknown background!" The co-pilot is not very capable, but his temper is not small, or from his heart, he doesn't think Xu Cang can replace him. his qualifications.Or, to describe it in a more accurate way, as he was born in Europe and the United States at the highest point of the civil aviation system, he has strong doubts about the quality of pilots in Asia, especially East Asia.

And it so happened that Xu Cang's face was the most typical East Asian appearance!
The co-pilot glanced at Xu Cang, full of contempt: "He guesses that he doesn't know what's going on with the plane now, so just hand it over to him?"

Xu Cang understood this sentence, he sneered, and pointed directly at the captain: "I'm talking, you translate it for him!"

The captain was startled: "What are you going to say?"

"You can just translate!" Xu Cang yelled, and turned to the co-pilot: "You say I don't know the status of the plane? No, I know more than you! Your PFD airspeed is inconsistent with the backup instrument airspeed, overspeed warning It kept beeping, but you did not take any action to correct it. It was probably a false warning at an unreliable airspeed. At this moment, the aircraft is still maintaining the level flight attitude and thrust setting at an unreliable airspeed, three degrees Attitude, EPR of 1.39, and the altitude is now close to 75 feet, so your current combined weight should be about [-] pounds."

"One of the stabilizer cut switches was closed, which means that the trim system has also failed, but it seems to be under control temporarily. It may be due to a loss of control of the stabilizer, or it may be due to unplanned stabilizer trim, but I am inclined to The latter. Because only the unscheduled stabilizer trim checklist alone requires a second activation of the stabilizer 2 cutout switch."

"The CDU screen is all black, and the navigation page is full of various fault flags, which means that it is not a problem with the CDU itself, but an extension of the flight management computer failure. The two flight management computers are useless, right? "

"At the same time, the heating switch of the right windshield is turned off. Maybe the windshield is overheated! However, the chances of the windshield overheating for no reason are very small, and most of them are short circuits caused by water seepage under the tight seal. It can be seen that there is no water leakage on the edge of your windshield. The bigger possibility is that the windshield is damaged! Of course, from a visual point of view, the damage is not serious, there should be only one crack. And, judging by your expressions, it is not so Fear, it’s just the rupture of the outer windshield!”

Xu Cang was talking, while the captain was translating. At the end of the speech, the captain's face was extremely exciting, and finally he said: "Holy Shit!"

Xu Cang slowly looked at the co-pilot: "You know who I am! So, can you give me your location now?"

　I originally wrote more, but I was dragged to do nucleic acid. Unexpected situation!Everyone calm down!
