Return to 2000: Captain of the Great Powers

Chapter 185 One after another!No solution!No solution! (Please subscribe!)

In the first-class cabin of flight 1009, the cabin has been adjusted to relatively dim lighting at this moment, and many passengers have already begun to rest.However, there were also many people who were not sleepy at this time, and started reading to do their own things, including Xu Cang.

Xu Cang was relatively comfortable and relaxed at this time, because in his memory, the air crash did not start until he crossed the English Channel.

According to subsequent investigation and analysis, the plane encountered icing conditions when flying over the airspace over France.However, it is not a very serious matter for an aircraft to encounter ice accumulation. You only need to use anti-icing equipment according to the situation. If the anti-icing equipment that comes with the aircraft cannot offset the deterioration of ice accumulation caused by the weather, then coordinate with the control An altitude or heading where icing is less severe.

In fact, in the area of ​​France adjacent to the English Channel, the weather is not good all year round, and it is not uncommon for heading aircraft to encounter icing conditions.Moreover, according to the cabin sound records in the black box, when entering the icy weather over Europe, the crew discovered it immediately and used the anti-icing equipment correctly.

After that, the crew continued to pay attention to the ice accumulation situation for a period of time, and did not visually observe the severe ice accumulation situation.Therefore, after turning on the anti-icing equipment, the crew did not apply to the control for other altitudes.

However, the route was covered by large rain clouds at that time, even if the application was made, it would probably make no difference.It is also possible that the crew heard the conversation between other crews and the controller on the radio and learned the relevant information, so they directly gave up the idea of ​​changing the altitude.

So far, the actions of the crew have actually met the standards, at least there are no major problems.The problem arose at the handover when the plane left French airspace and entered British airspace.

In fact, even though the investigation of the Great Britain Air Disaster has been completed in later generations, the investigators are still not very clear about the cause of some things. For example, the icing situation of the aircraft, which had been stable before, deteriorated rapidly within 5 minutes of crossing the airspace boundary. .That is, after entering the sky over the British islands, the plane began to lose control under severe ice accumulation, which eventually led to an irreparable and huge disaster.

It is precisely because of the information from later generations that Xu Cang can maintain a relatively relaxed state at least before the plane enters the European continent.Otherwise, Xu Cang felt that his spirit would be unbearable if he would be stretched for more than ten hours.

The only consideration now, though, is the timing of access to the cockpit.

Xu Cang folded the magazines he had read and threw them aside, the movement startled Leo who was sitting next to him. Leo took a nap just now, but now he woke up refreshed.

Seeing that Xu Cang hadn't rested yet, Leo immediately said, "Mr. Xu, do you have a place to go after landing? Have you booked a hotel?"

Xu Cang yawned: "No!"

He didn't really go to the UK for business or tourism, so how could he really book any hotel?If according to Xu Cang's plan, after landing, he should be taken away by the British Civil Aviation Authority CAA, and the British Civil Aviation Authority will be responsible for his board and lodging.

"Ah? Mr. Xu, are you planning to find a temporary place to live after landing? Will it be inconvenient?" Leo is very enthusiastic: "Mr. Xu, if you don't mind, you can come with me after landing. Go to my suburban villa in London for one night, just in time to find a place to live."

At this time, Song Xinyang interjected: "Mr. Leo, will you be staying in a suburban villa for a while?"

"Yes!" Leo replied naturally, and soon he understood Song Xinyang's thoughts, and then repeated: "Mr. Song, the next period of time is my vacation time. If you come to my house as a guest, I will It would be very welcome. But if it is to discuss business, it will make me feel quite troubled."

Song Xinyang's face froze, he really planned to visit Leo's villa later, the purpose of course was related to the A380 engine issue.

Song Xinyang knew that this kind of stalking behavior would arouse Leo's disgust, and he was unwilling to do so.After all, Song Xinyang is also a person with a head and a face, and this kind of dog skin plaster is really a shame.

However, Rolls-Royce has already been pushed to the ground by General Motors and Pratt & Whitney in the field of narrow-body aircraft. If it cannot open up the field in the field of wide-body aircraft, it will have to give up the civilian market.

However, as an aero engine company, if it loses the civilian market, wouldn't it be a waste of time?Besides, in the field of military engines, Pratt & Whitney is a more difficult opponent than GM.

If things go on like this, will Luoluo repeat the past of bankruptcy and reorganization?

The more Song Xinyang thought about it, the more he felt that there was no way to go. For the present plan, he still had to gain the priority in the competition with the GP7200 engine, otherwise it would not seem so smooth to use other channels.

However, it is impossible to take shortcuts in the research and development of engine research and development in conventional methods, so Luo Luo looked for Xu Cang in order to conduct real machine tests as quickly as possible.

Regardless of the means, even in the age of extremely advanced computers, there is nothing more accurate than the problems that can be found by actual machine testing.However, if a real machine test is carried out rashly, it is very likely that both human and machine are lost, and the data cannot be saved at all.

It only makes sense if you can safely fly the plane down in a real-air test!It is precisely because of this high difficulty that the importance of test pilots is extremely precious.

However, now Luo Luo needs more than ordinary test pilots can accomplish, and Xu Cang is an important choice for his replacement.However, Xu Cang's conditions were too exaggerated, and only Luo Luo's top management had the power to make decisions.

Judging from the current situation, Song Xinyang felt that Luo Luo would finally agree to Xu Cang.This is when the heaven and the earth work together, and the heavens are helping Xu Cang.

Song Xinyang was distracted by Leo and stopped talking, but Xu Cang whispered to Leo: "If I want to enter the cockpit, can you do it?"

Leo was startled, and then suddenly realized: "Mr. Xu, are you curious about the cockpit of the 747? Boeing's cockpit is similar. Are pilots like Mr. Xu interested?"

Ordinary people basically have no chance to enter the cockpit. It is normal to feel novelty in the cockpit of an airplane.But it is rare to hear that pilots are interested in feeling in the cockpit.When something becomes a job for a living, it often means a loss of interest.

Of course Xu Cang was not interested in the cockpit of the 747.Of course, it’s not that he’s not interested in the cockpits of all planes. If Xu Cang chooses for himself, Xu Cang might be interested in the cockpit of the A350, or the A350 is Xu Cang’s favorite plane, although he himself also flies several times.

Originally, Xu Cang was still thinking about how to find a reason, but now Leo found it for Xu Cang first, so Xu Cang can't use the slope to get off the donkey?Immediately nodded like a chicken pecking rice: "Yeah, I have never seen the cockpit of a 747, I am yearning for it! You know what I am yearning for, it is very urgent."

"It's urgent, I know." Leo nodded half-understanding: "However, Mr. Xu! I remember that you should have driven a 747 before, that is the time when the 747S2 switch in your country had an accident."

Although the accident occurred in China at that time, there were many 747 models abroad.The follow-up modification plan issued by Boeing involved all relevant types of aircraft, which naturally included many foreign airlines, and things became more troublesome.

As a friend in the same industry, Airbus is very concerned about Boeing's embarrassment, so it's not surprising that Leo knows this.

Song Xinyang next to him heard Leo mentioning the S2 switch, and his face changed slightly.In fact, it was because of that incident that Luoluo Company began to notice Xu Cang.Therefore, it was not that Luo Luo found Xu Cang temporarily after the accident of the Concorde, but on purpose.

"Ah? This. This..." Xu Cang completely forgot that he was driving a 2 in the S747 switch incident, and now the lie is a little bit hard to cover.However, Xu Cang's brain turned quickly: "At that time, my eyes were injured, and I didn't really see what the cockpit looked like."

Leo admired it very much: "I heard about this incident. At that time, the cargo door opened unexpectedly, and an explosive decompression occurred in the cabin. Mr. Xu's eyes were bleeding, and his ears seemed to be deaf. It was because of blindness, Mr. Xu It is rare in the world to be able to bring down the plane."

For this kind of compliment, Xu Cang didn't feel the slightest ups and downs in his heart. What he wanted to know more was whether Leo could solve his problem of getting into the cockpit.

If Leo can't handle it well, Xu Cang has to find another way!
"Mr. Leo, can you let me into the cockpit?" Xu Cang tried to bring the topic back to the direction he wanted.

"It should be no problem. We have a lot of cooperation with British Airways. This time my ticket was arranged through my senior executive friend at British Airways. The crew of this flight knew my identity. If I want to go to the cockpit , should be fine."

"Then what if I want to manipulate it by the way?" Xu Cang continued to ask.

Leo's face froze: "Mr. Xu, you are too humorous."

Hearing Leo say that, Xu Cang couldn't help showing an embarrassed rather than polite smile.It doesn't matter, as long as he can get into the cockpit, things will be easy to handle later.

Seeing that Xu Cang did not make further demands, Leo couldn't help but breathe a sigh of relief.Xu Cang is a pilot. Although he is a CAAC pilot, it is very difficult for ordinary people to enter the cockpit, but as long as he steps into that circle, many things are much easier.

However, entering the cockpit and operating the aircraft are not the same concept.

Xu Cang adjusted the seat back, thinking about sleeping for a while and recharging his energy.He just put the back of the chair back a little and asked the flight attendant for another blanket to cover his knees. As soon as Xu Cangfu lay down, he felt a strange feeling.

I saw that he slowly raised his arm, raised it flat, and was at the same height as his eyes.Under the illumination of the reading lamp, Xu Cang suddenly found that all the fine hairs on his arms stood up, but he didn't feel any cold.

"what happened?"

Xu Cang instinctively noticed something strange, but he couldn't understand what happened at this moment.In Xu Cang's memory, flight 1009 should have been safe and sound before it arrived in the European continent. How could there be such a change?

Xu Cang suddenly had an uneasy thought in his heart. Could it be that the problems encountered by flight 1009 have changed?

Now, in the cockpit, the captain and first officer looked at the windshield as if it had come to life.As the plane moves, fine electric arcs like spider webs will spread out from time to time on the windshield, and at the most exaggerated time, it can completely cover the entire windshield glass.

The captain held the steering wheel with his left hand and removed his right hand from the thrust handles to turn the aircraft's landing lights on.Under the strong beam of light from the landing lights of the plane, as far as the two people could see, they could indeed see that the plane was surrounded by some impurities, but neither the captain nor the co-pilot could tell what these things were.

"Is it a cloud?" At this time, the co-pilot felt a little guilty for no reason, although he didn't know why.

The captain turned off the landing light: "I don't know. Let's do the checklist first, deal with the airspeed problem, and then apply for a change of flight altitude."

Even though he hadn't encountered a more dangerous situation at this moment, there was a wave of uneasiness in the captain's heart.If a reliable source of data can be identified, then subsequent flights are relatively safe.Regardless of whether it was an alternate landing or any decision, the captain had the confidence to carry it out.

But if it is impossible to determine a reliable data source and all rely on wrong data instructions, then the subsequent flight will be difficult.

"Okay." The co-pilot scratched his head to briefly release his inner anxiety.However, he was quite professional, and quickly restrained his emotional fluctuations, and continued: "Cross-check the airspeed display on the PFD and the standby airspeed indicator, if the difference between the value of the standby airspeed indicator and the standby airspeed indicator exceeds ten knots, then was deemed unreliable."

The captain was concentrating on controlling the plane at the moment, and just gave an order: "Compare it!"

"Wait a minute!" At this time, it was too dark inside the cockpit, and the PFD could still be seen clearly because it was an electronic display.But the spare gauges are all mechanical, but without a backlight, the co-pilot can't see the values ​​on the spare gauges at all.So, the co-pilot unfastened his seat belt, stood up slightly and turned the lights in the cockpit to dim, so that he could see the display of the mechanical backup instruments clearly, and the lights would not be too bright, making it hard to see. Clear the outside world.

After adjusting the brightness of the lights in the cockpit, the co-pilot lowered his head, approached the instrument panel, and compared the left and right PFDs and spare instruments.He quickly discovered the problem, and hurriedly said: "Captain, the value on the standby instrument is consistent with my side, and the airspeed on your side seems to be wrong."

The captain did not immediately acknowledge the co-pilot's observations, but raised his right hand and pointed to the steering wheel on the co-pilot's side: "You take control, I'll take a look!"

The co-pilot understood and quickly took over the control of the plane.After confirming that the co-pilot temporarily controlled the plane, the captain spared no effort to personally compare the values ​​of the three instruments.Sure enough, among the three-way instruments, the airspeed indicator on the co-pilot's side is the same as the backup instrument, and the difference is on his own side, and the difference in value is still expanding.

Not long ago, the difference was around seven knots, but now the difference is more than ten knots, which perfectly matches the description in the checklist.

After confirming, the captain signaled himself to take over the plane again, and said at the same time: "Well, I have a problem here, let's continue with the checklist."

"Reliable airspeed data sources can be identified, air data source selector. Two, select reliable ADC."

After the co-pilot finished reading, the captain hummed: "Come on!"

After getting confirmation from the captain, the co-pilot put his hand on the knob of the air data source selector: "Captain, turn to me."

"Ok!"

After the second confirmation, the co-pilot turned the knob to his side.In this way, the airspeed data on the captain's side also uses the information from the air data computer on the copilot's side.

After selecting the ADC data on the reliable side, the PFD airspeed display on the captain's side immediately experienced a huge instantaneous change, and finally it was consistent with the airspeed display on the co-pilot's side.

"It seems to be fine!" The captain was slightly relieved, but fortunately the airspeed data from the co-pilot was normal.As he said that, the captain waited for a few seconds to confirm that there was no problem in the follow-up, and switched on the autopilot.

With the autopilot switched on, the captain hadn't spoken yet, but the co-pilot spoke first: "Captain, shall we go back?"

There are still more than ten hours of flying in the future, so I can't continue flying with this fault.The airspeed aspect, if developed, is an extremely difficult problem.The co-pilot is obviously not willing to take risks.

In fact, at this moment, the captain also wanted to retire.Although the fault has been dealt with now, it doesn't mean the captain is relieved. On the contrary, he always feels that something is wrong in his heart, but he can't say it.

The captain thought for a while: "Let the purser call Tom in, and the three of us can discuss it. Also, ask if there is room above [-] feet."

In foreign countries, imperial units are generally used, not metric.The captain seemed concerned about some unknown material encountered at the plane's altitude, and the Tom he was talking about was really the second captain of the flight.

"Captain, our plane is a bit heavy this time, and FL400 is already close to the ceiling." The co-pilot reminded.At the same time, adjust the CDU to the cruise page, which shows that the ceiling of the aircraft at this moment is about 4 feet.

The ceiling of the 747 can reach nearly 4000 meters, which is almost 747 feet.However, that doesn't mean the [-] can reach that height in every case.For this ultra-long-range intercontinental aircraft, due to carrying a large amount of fuel, the weight of the initial aircraft is extremely high, and the aircraft may not reach the so-called ceiling.

Judging from the calculation results of the flight computer, the altitude of FL400 is already extremely close to the theoretical ceiling at the moment.If it is too close to the ceiling, the stability of the aircraft in pitch will not be guaranteed.

It was based on this concern that the co-pilot did not immediately agree to the captain's altitude change order.

"It's okay! Let's climb up first. If you lower the altitude now, there may be some problems with the follow-up fuel." The captain said.

Generally speaking, the higher the plane flies, the more fuel-efficient it is.The cruising altitude of the flight plan of Flight 1009 is based on FL360.If it falls below the predetermined altitude so early, it will easily consume more fuel than planned. If it flies at a low altitude for too long, it may find some fuel problems at the end of the voyage.

Of course, the possibility of this problem is not very high.However, the captain should always be in charge of the overall situation and prevent possible dangers.

The co-pilot thinks it makes sense, if he finds that it is wrong to be at a high altitude later, he will come down again at worst.So the co-pilot didn't say anything more.

The right hand just touched the call button of the radio, but before he pressed it, his eyes suddenly noticed that the unplanned stabilizer trim light suddenly turned on.

It was less than a second after the fault light came on, and the autopilot that was turned on suddenly turned off by itself.The captain was still thinking about something just now, and was taken aback by the sudden warning sound of autopilot disconnection.

However, the captain still instinctively held the steering wheel with one hand and the thrust handle with the other to stabilize the aircraft first, and then check what went wrong later.

However, after the autopilot was disconnected and the captain reconnected to the manual control, there was no loss of control of the aircraft. It seemed that the autopilot was simply disconnected.

The captain saw that there was no problem, and then he was about to switch on the autopilot.However, as soon as the automatic driving button was pressed, the automatic driving was disconnected by itself, and the alarm continued to sound.

The captain immediately suppressed the sound of the siren, and said angrily, "What's the problem?"

It can be seen that the captain's mentality has changed a little at this moment, and he has become irritable and anxious, otherwise he would not have ignored the unplanned stabilizer trim fault light that was close at hand.

"Captain, the unplanned stabilizer trim light is on." The co-pilot reminded, and at the same time looked at the captain with some concern: "Captain, are you okay?"

Only then did the captain notice the existence of the fault light, slapped his forehead, and waved his hand: "I'm fine, let's do the checklist."

This light is on to indicate that the stabilizer is moving but there is no signal and the automatic cutoff does not work. In addition, when the autopilot is turned on, the spare stabilizer trim switch is used. Based on the antecedents, this fault light should belong to the latter.

"Oh!" The co-pilot put down the quick checklist just now, and brought it up again.At this moment, he already had some bad feelings in his heart. While looking through the corresponding checklist, he said casually: "Captain, why don't we return to the flight, I don't feel right."

To be honest, not only the co-pilot felt something was wrong, but the captain also had this mysterious and mysterious feeling.Otherwise, he wouldn't have been distracted just now.

It's just that their crew configuration is relatively tight in terms of duty periods and space-time constraints.If it is a return flight, it may be timed out later, and if we have to wait another day in Jakarta, the company's subsequent plans will undergo relatively large changes.

This kind of behavior that affects the whole body makes the captain really timid about the return flight.

After cursing in a low voice, the captain could not help complaining: "The company should arrange two independent crews."

If there are two completely independent crews, plus the 747 has a rest area that meets the requirements, then the duty period and empty time can be greatly extended. Even if it returns, there will be no risk of overtime, and it will not be so bad. Awkward.

After finishing speaking, the captain didn't complain anymore. He was afraid that his emotions would spread to the co-pilot, so he volleyed with his right hand and said, "Let's do this checklist first, and we'll talk about it when Tom comes over."

If you really want to return, you must discuss it with the second captain.Now the captain himself is a little unsure about paying attention, and needs another professional to provide advice.

The co-pilot keenly felt that the atmosphere in the cockpit was not right at the moment, but he couldn't make a decision even if he spoke lightly, so he could only make a checklist first.

The checklist for Unplanned Stabilizer Trim is uncomplicated.Under the captain's approval, the co-pilot put the two stabilizer cut-off switches in the cut-off position, and on the premise of disengaging the autopilot, put the stabilizer trim 2 cut-off switch in the automatic position.

At this time, according to the requirements of the checklist, it is necessary to observe the trim of the stabilizer.After waiting for a few seconds, the captain tapped the main electric trim, and the trim wheel responded immediately.

The amount of trim given by the captain was very small, and the trim wheel only turned less than one turn.

"No problem?" The first officer couldn't see the movement of the captain's fingers, so he didn't know whether the trim wheel's response matched the captain's input.

Fortunately, the captain nodded: "No problem."

While speaking, the captain stabilized the plane, released the stick force, and then switched on the autopilot.After waiting for five seconds, the unplanned stabilizer trim light finally stopped coming on, and the autopilot finally remained on continuously.

Although the automatic driving was finally connected, the fault seemed to be resolved.But in fact, not only did the captain's inner anxiety not decrease, but it expanded rapidly.

The 747 is an extremely sophisticated collection of machines.It's not that it won't fail, but it should have two unrelated failures in a short period of time.

Airspeed inconsistencies and unplanned stabilizer trim are minimal in terms of system relevance from any standpoint.Yet they happened one after the other within brief intervals.Now it's just that the plane is really malfunctioning, so the possibility is too small.

The captain's thinking now is that there is a source of the aircraft accident, which caused the airspeed inconsistency and the unplanned stabilizer trim problem, but the biggest problem now is that he doesn't know what the source is.

"Notify the flight crew, and then contact the control." The captain shouted.However, the moment he spoke, the captain immediately changed his mind: "Contact the control first and ask for a change in altitude. Let's leave here first."

Although he doesn't know what the source is, but out of professional instinct, the captain feels that it has something to do with the cloudy things outside.No matter what it was, his first thought now was to escape from it, and we'll talk about it later.

"I see!" Perhaps feeling the anxiety in the captain's words, the co-pilot didn't stop for a moment, and directly called the control: "Jakarta, British Airways 1009!"

"BA 1009, Jakarta, please speak!"

"We encountered more than moderate icing at FL360 and hoped to climb to FL400." The co-pilot was quite talkative.

He can feel that something outside is problematic, but he doesn't know what it is, so don't use this as an excuse, otherwise if they encounter some ignorant controls, they will not be able to distinguish the primary and secondary relationship, just I want to figure out what the unknown substance encountered by the crew is, rather than requesting a high altitude for the crew as soon as possible.

Encountering more than moderate icing is a relatively urgent and easy-to-understand reason.Sure enough, after receiving the application from the crew, Jakarta control immediately said: "British Airways 1009, wait a moment, I will apply for altitude for you."

At the moment, the plane hasn't flown very far, at least under Jakarta's area control.Here, there are a little more planes, so you may need to wait a while when changing the altitude. If you fly farther and reach the ocean, there are basically no restrictions, and the width of the route will be relaxed a lot.

Although the Jakarta control said that it was necessary to apply, the captain based on experience, even if there are other planes in this position, the number should be very small, and there is a high probability that the control will agree in the end.

"Okay, tell the crew." The captain instructed.Now is the time to discuss the return flight with the second captain.

However, at the moment when the captain's words fell, an FMC-related fault flag suddenly popped up on the navigation page.The co-pilot lowered his head subconsciously, and suddenly found that the CDU display on his side had directly turned into a black screen.

"This" was obviously the first time the co-pilot encountered such a situation, and was immediately stunned.

"Damn!" The captain's mentality became unstable in an instant. First, the airspeed was inconsistent, then there was a trim problem, and now the flight management computer also had a problem. There was no need for the second captain to come over to discuss it. The captain immediately said: "No Flying forward, let's go back and inform Jakarta control that the plane is malfunctioning and request to return to Jakarta."

The co-pilot felt relieved when he heard the captain say to return to Jakarta, and impatiently reported to Jakarta: "Jakarta control, British Airways 1009, our plane is malfunctioning, apply to return to Jakarta."

At the end, the captain interjected: "Application for radar guidance, our navigation system may have some problems."

In fact, there are more than one flight management computer on the plane, even if only one is available, it can meet the needs of aircraft navigation.But the problem is that now the captain has no confidence in the plane, as if the plane could break down without warning, it would be more convenient for Jakarta control to conduct traditional radar guidance.

However, the control side in Jakarta is obviously a little confused about the situation.Not long ago, flight 1009 was still applying for a high altitude due to icing above moderate levels. Why did it become a return flight within a minute.

"British Airways 1009, wait a moment, I want to ask the airport if it can be accepted."

It doesn't mean that once the crew decides to return, the controller can immediately agree.Some airports do not accept alternate landings, especially for large aircraft such as 747s.Therefore, the area control needs to contact the airport first to confirm that the crew can accept the return flight of British Airways No. 1009.

If you don't go through this step, when the plane is about to reach the sky above the airport, the airport will suddenly say that the airport does not accept 747 alternate landings, then the matter will be embarrassing.

The captain understood the control, so he just added: "British Airways 1009, please hurry up if it is convenient."

"British Airways 1009, what is wrong with the plane now? Do you need our help?"

"We have problems with the instrument system, navigation system, and control system. The situation is complicated. We don't need help at the moment. If you can, please help us coordinate the high altitude and return permission as soon as possible." After the captain finished speaking, he directly instructed the co-pilot : ""FMC Left/Right Checklist"!"

"Okay, okay!" The co-pilot promised again and again.However, it was obvious that the co-pilot was quite unfamiliar with this failure phenomenon, and after searching for a long time, he still couldn't find the corresponding checklist.

The captain was also anxious, and said directly: "Flight management and navigation chapters, the first one is the checklist."

"Oh, let me look for it!" Under the urging of the captain, the co-pilot became even more impatient, and couldn't even turn the page smoothly.

The captain was uncomfortable watching, and in a hurry, he didn't even wait for the co-pilot: "I'll do it first!"

As he spoke, the captain muttered: "The FMC selector selects the working side."

While speaking, the captain raised his right hand, put the FMC selector knob to the left, then engaged the autothrottle, and continued: "The navigation source selector selects the working FMC."

As before, the captain turned the NAV SOURCE selector to the left position.

Generally speaking, under this maneuver, the FMC on the first officer's side will also use the data from the flight management computer on the left, just like the same airspeed data source was used by both sides just now.

However, the moment the captain turned the navigation source selector to the left position, the screen of the CDU that was still running on the left side went black instantly.All of a sudden, various fault flags began to appear on the navigation page, and the auto throttle that was just turned on was immediately disconnected.

"Fuck! Fuck! Fuck!" The captain cursed three times in a row, but his hand movements did not stop, and he turned the navigation source selector to the middle CDU position again.

Then, the captain looked at the course of the disembarked aircraft, fine-tuned it so that the aircraft could be controlled on the course, and at the same time pressed the button for course selection.Due to the failure of the dual FMC, the aircraft has lost the function of horizontal navigation, and can only choose the traditional heading selection.

"Notify the control, the navigation system is faulty, we may not be able to accurately maintain the route, and apply for a deviation maneuver of three nautical miles left and right."

At this moment, there is only a MAP failure flag on the navigation page, and no navigation information can be seen at all.Although he is maintaining the course now, under the influence of the wind, he will gradually deviate, so he must report to the control.

However, when the captain gave the order, he suddenly noticed that the airspeed of the airspeed indicator on his side began to increase for no reason, and he obviously didn't push the stick or put the gas on.

"Wind direction and wind speed changed?" The captain instinctively thought of this idea.

However, when he saw the real-time wind direction and speed on the display, he found that the wind has been steady.

"No, no, no! Something went wrong, something went wrong!" At this moment, no matter how dull the captain was, he knew something was wrong!
