Return to 2000: Captain of the Great Powers

Chapter 311 PW4000-112 and Boeing 777!

After Xu Cang left the economy class, he went straight to the cockpit in front.

It can only be said that the identity of the ICAO Commissioner is quite bluffing.At least at the beginning, when Xu Cang mentioned that he was going into the cockpit, the first reaction of the cabin manager was not to ask, but to become more vigilant. It was not until Xu Cang revealed that he was the flight commissioner of the International Civil Aviation Organization that the cabin manager did not want to go into the cockpit. He half understood and said that he could ask the cockpit.

When passing by the first-class cabin, the marketing director of Kingfisher Airlines grabbed Xu Cang, obviously panicked: "Boss, are you okay?"

"I don't know, I want to go into the cockpit to have a look." As he spoke, Xu Cang began to turn over the luggage rack.

Xu Cang didn't have to bring his own flight license since the certificate of the flight commissioner of the International Civil Aviation Organization came down, but this certificate must be brought.As long as you are a member of the International Civil Aviation Organization, you must recognize this certificate, which is much easier to use than the CAAC flight license.

Xu Cang didn't have much luggage, so he quickly found his documents from the bag.

Over there in the forward cabin, the cabin manager is on an intercom with the cockpit.Seeing that Xu Cang seemed to have found his ID, he gestured to Xu Cang to come over.

Xu Cang patted the marketing director on the shoulder, and walked over with his ID.

"Can I take a look?"

This Xu Cang didn't mind, and handed the certificate to the cabin manager: "If you can't tell the difference, you can ask the people in the cockpit to check, and they can ask the control for verification."

The cabin manager looked at Xu Cang's certificate several times. It was really the first time for her to see the ICAO certificate, so she couldn't tell the difference clearly.

"Excuse me, I need to show the captain, can you step back a little bit?"

After a while, the door of the cockpit was about to open, Xu Cang's current position was a little too close, and he needed to keep a safe distance.

"Well, please hurry up." Xu Cang stepped back a little distance, and stood at the entrance and exit of the front cabin workshop.

The cabin manager nodded, said a few words to the cockpit, and then closed the curtain of the front cabin work room to block the view of the work room.

Xu Cang was not in a hurry, he just stood there.Apparently the cabin manager listened to his words. Within two to three minutes, the curtain was pulled aside, and the cabin manager stretched out half of his body: "Sir, the captain invites you into the cockpit."

Xu Cang hummed, lowered his head slightly, and crossed the curtain to find that the cockpit door was ajar, so he opened the cockpit door very naturally, and stepped in.

Unlike Xu Cang's expected scene, the atmosphere in the cockpit of this plane is quite relaxed.After Xu Cang entered, the captain handed back the certificate to Xu Cang, and said with a smile: "Sir, our company did not mention that there will be personnel from the International Civil Aviation Organization to check on the plane, or do you mean that you are not informing the airline?" company's?"

Generally speaking, whether it is the local Civil Aviation Administration or the International Civil Aviation Organization, they will basically notify the airline in advance when they board the plane to monitor a certain flight segment.Of course, if you want to achieve a surprise effect, some inspectors will delay the notification time until the door is closed, so that the airline has no possibility of preparing in advance.

However, it is relatively rare for Xu Cang to fly for several hours before revealing his identity.

No matter how long the delay is, it is a matter of courtesy to inform the relevant airlines before takeoff, and it is generally accepted as an unspoken rule.

Of course, Xu Cang did not notify in advance, and the captain and co-pilot in the cockpit did not dare to express too much.

"It's rare to monitor an intercontinental segment." At this time, the co-pilot also said.

Unlike in China, there is an obvious age difference between the captain and the co-pilot.In foreign countries, it may even happen that the co-pilot is older than the captain, which is caused by various reasons.Moreover, the average age of captains abroad, especially in Europe and America, is definitely older than that in China.This made Xu Cangchu see that the two people in the cockpit were all uncles in their 40s, and there was basically no external difference in age.

Xu Cang took his certificate, glanced at the engine display, it seemed that there was nothing wrong with it at first glance.

"No, this is not route monitoring." Xu Cang waved his hand, first setting the tone.

Although the captain and co-pilot looked relaxed, their inner behavior was not consistent with their outward appearance.At least the captain breathed a sigh of relief when he heard Xu Cang say that it was not a route inspection.

The co-pilot was stunned for a moment, and then asked, "Then Mr. Xu, what's the problem?"

Xu Cang did not answer immediately, but scanned the entire cockpit panel and DU display, and asked a little strangely: "Are there any warning displays in the cockpit just now? For example, related to the power system?"

"Ah?" The captain and the co-pilot looked at each other. They were chatting just now, but they didn't keep looking at the panel.

It's not that the captain and co-pilot are lazy. If you don't do something during such a long flight, you will soon be overwhelmed.Even the standard operating procedure manuals of many airlines are based on chatting properly after a stable cruise to ensure that the pilots have a relatively stable brain vitality.

However, Boeing's design of the warning system has its own logic, that is, it separates warnings within and outside the pilot's field of vision.

The warnings within the pilot's field of vision are easier to see. After all, even when the pilot is chatting, most of them are usually ahead of them. When any light is on, they will be aware of it immediately.However, the cockpit is very large and there are many switches on the panel, and the pilot can only see a part of the panel when looking up.Those areas of the panel beyond the pilot's field of view that have warning lights are more likely to go unnoticed.

At this time, the signal board function in the Boeing aircraft is reflected.

The so-called signal light is directly in front of the pilot's field of vision, and it is impossible not to see it.Once the warning lights outside the pilot's normal field of vision come on, the signal lights will also come on.Moreover, the signal board lights will indicate that there are warning lights in that part of the area, which is very eye-catching.

Therefore, unless both of them are asleep, the pilot will be able to notice if there is an abnormal warning light.

"No." After being puzzled at the beginning, the captain quickly gave an answer, and seemed to add a sentence to increase persuasiveness: "I'm sure."

The captain said so, and Xu Cang couldn't question it anymore, and they had no position to lie to themselves about this kind of thing.

Xu Cang turned to the DU displayed on the engine and nuzzled: "Are there any abnormalities in the speed and vibration?"

"This." The captain hesitated: "I can be sure that there is no overrun situation, but if it means that the value within the limit range fluctuates, I am not sure about this."

Some faults need to be fermented for a period of time, such as engine surge, and the speed will fluctuate abnormally before it develops beyond the limit.However, even if there is no over-limit display, this level can be detected by body sensation alone.

The co-pilot turned on all the engine display data: "There is no problem now."

Xu Cang stood behind and glanced at the engine parameters, all of them were indeed within the limits.Previously, in the economy class, Xu Cang saw some unknown flames appearing at the intake port of the No. [-] engine, which can be reflected in the data. The speed of the No. [-] engine fluctuated only slightly, and the vibration value was higher than that of the No. [-] engine, but Not much higher.

During flight, the speed of the aircraft engine is constantly changing. Even though the speed of the No. [-] engine is more stable than that of the No. [-] engine, the speed of the No. [-] engine fluctuates a bit frequently, but this cannot be used as a basis for judging the fault.

Xu Cang pondered for a moment, the current situation is indeed a bit embarrassing.He felt like something was wrong, but the data didn't support his idea.

The captain could see the confusion on Xu Cang's face, at least it seemed that the Commissioner of the International Civil Aviation Organization was not targeting him, so he became bolder and asked, "Did you find any problems? "

"Where's the maintenance record book?"

"It's the cabinet under the seat next to you." The captain pointed, perhaps to prove that he wasn't being perfunctory, and he added: "Before takeoff, this plane didn't have engine-related DD items."

Xu Cang didn't respond to these words, he lowered his head and turned over the cabinet, and quickly found the maintenance book.

The Boeing 777-200 is the oldest model of the 777.Of course, even the original model is relatively new for the 777.

Although the Boeing 777 was fully put into commercial use after Xu Cang's Daocheng test flight, this Boeing 777 has actually been in operation for three years.Any large airliner will undergo a test flight before general commercial flight, and the duration varies.

Some major airlines will get early access to a batch of Boeing 777 with airworthiness restrictions.The so-called restricted airworthiness means that these Boeing 777s can only fly on designated routes, and they must follow higher standards in the selection of crew members.

The previous problem with the Boeing 777 was a flight involving the polar regions, otherwise Xu Cang would not have needed another test flight in the conventional sense.

As a major European airline, it is reasonable for British Airways to receive the first batch of Boeing 777s and undertake trial operations.

At the beginning, the captain was relatively relaxed, after all, there was no abnormal display in the cockpit.But seeing Xu Cang being so caring, he felt a little thumped in his heart.

It's not really a problem!

The title of ICAO flight commissioner is still very valuable.

Xu Cang flipped through the maintenance book silently, some failures did not appear suddenly, there may have been some symptoms before.If you have encountered any problems before, the crew or maintenance should record it, which is a very useful reference.

However, it is obvious that this maintenance book has just been replaced.There are only records from the last half month or so.

Xu Cang finished flipping through it within a few minutes, and there was nothing suspicious in it.

"Am I really suspicious?" Xu Cang said to himself.

What he said was in Chinese, the captain couldn't understand, but the captain basically guessed what Xu Cang was doing, and added: "I haven't heard of any problems with this plane before."

"Really?" Xu Cang thought about it for a while, and decided that there was something wrong with the plane, "Come over with me, and take a look at the engine with me, and you will understand what I am for."

"Ah? Is that so?" The captain glanced at the co-pilot, but didn't hesitate too long: "Then you look at the plane, I'll go out for a while."

At this time, the regulations for the cockpit are not strict yet.Otherwise, at the back, a single crew member is not allowed to stay in the cockpit.

Xu Cang put the maintenance book on the chair behind, and came out first, and then the captain followed.

Obviously, the cabin manager didn't expect the captain to come out, so he was a little surprised.

Without waiting for the cabin manager to say anything, the captain directed to the cabin manager: "I'll go to the economy class, you look at the cabin door."

After finishing speaking, he pushed Xu Cang: "Mr. Xu, let's go."

Xu Cang didn't stop, opened the curtain and went directly to the economy class.When passing the first-class cabin, the marketing director was full of question marks, why did he call the captain out?

What Xu Cang wanted the captain to see was nothing but the flickering light at the air intake of the No. [-] engine.

In fact, Xu Cang still can't figure out what this thing is.

Even Xu Cang couldn't understand the things that ordinary captains would be at a loss most of the time.

Under the surprised gazes of the passengers in the economy class, the captain leaned over the porthole, frowning into a "Chuan".

"Do you know what's going on?" Xu Cang deliberately lowered his voice so as not to magnify the matter.

The captain shook his head: "Let's go back to the cockpit."

It is not a good thing for the crew to stay in the cabin for a long time. It is easy to cause misunderstanding among passengers, and the most serious one will cause panic.At least this is not a place for talking.

Xu Cang also agreed with this statement and walked forward first.

Before entering the cockpit, the captain stopped for a while, and told the cabin manager: "Let David come over."

David is the second captain of this plane, and there must be two crews for such an ultra-long-haul route.The Boeing 777 has a special crew rest area, and it is estimated that the other captain is still sleeping.

The cabin manager was taken aback, this is not a good sign: "Captain, is there any problem with the plane?"

"You can just call David over here." Don't tell the flight attendants about the undecided issues, laymen tend to fantasize and scare themselves.

After speaking, he didn't talk to the cabin manager, and went directly into the cockpit.

Xu Cang followed in without saying a word.

The two sat down, and the captain had no expression on his face except doubts: "Mr. Xu, is that what you are worried about?"

"Isn't that worth worrying about?" Xu Cang said in a deep voice, "There is no ice or volcanic ash, and the fire light is very strange."

"Maybe it's the reflection of moonlight or starlight?" The captain guessed, "As the plane moves, the angle of reflection changes, so the light appears and disappears from time to time?"

The captain's guess was not unreasonable. The circle of the engine inlet was very smooth, and there was indeed a possibility of reflection.However, Xu Cang felt that this statement was somewhat difficult to accept.

"The engine data are all normal." The captain didn't say anything later, but the meaning was already obvious, so let's forget about it.

Indeed, judging that there is a problem with the engine just by a burst of bright light from nowhere, it is really a shadow of a snake.Moreover, the plane has had no recent engine-related failures, and there is no evidence to support it.

"Where is it now?" Xu Cang asked suddenly: "If you want to make an alternate landing, is there any big airport nearby?"

The captain's face changed slightly: "If you want to make an alternate landing, the nearby large airports that can be used for alternate landing are Vienna and Belgrade. However, it is impossible to alternate landing just based on the current situation."

Xu Cang is also a pilot. From the perspective of most pilots, this incident is a bit outrageous.It is even said that Xu Cang himself has no confidence.

When he was in the first-class cabin before, he could still vaguely feel the vibration of the plane, but he basically couldn't feel it when he entered the cockpit.This shows that the vibration is actually very weak, and it seems that there is no evidence of any malfunction.

"I asked another captain to come over. In the next three hours, our two captains will be monitoring in the cockpit. How about this?" The captain said: "If there is a breakdown within three hours, we can still make an alternate landing in Istanbul. "

This is the greatest respect the captain gave Xu Cang.

Carrying out the dual-pilot cruise for an unknown light, that is, because of Xu Cang's status as a flight commissioner of the International Civil Aviation Organization, otherwise he would have ignored it.

"Three hours." Xu Cang thought for a while, and agreed with the captain's opinion.

If there is really a problem with the plane, the three-hour fermentation time can basically be determined.There are two captains in the cockpit staring at it, so there should be no problem.Neither the crew nor the airline would accept an alternate landing just because of a flash of light.

"That's it." Xu Cang felt that he could accept the captain's proposal: "Thank you for your hard work, I'll go out first."

The captain nodded: "If there is anything unusual, I will notify you in time."

"It's troublesome."

Just as Xu Cang was about to leave, when he saw the open maintenance book on the chair behind him, he wanted to close it and put it back in the cabinet.

But suddenly, Xu Cang saw a routine engine maintenance was recorded on the opened page.

This is not considered a failure record, but just regular periodic maintenance.Of course, the problem is not maintenance, but another matter.

The captain thought that Xu Cang had gone out, but there was no movement for a long time. Looking back, he found Xu Cang staring at the maintenance book in a daze.He just wanted to ask, but he heard Xu Cang ask: "Isn't the engine of your plane GE90?"

The captain hummed: "That's right, it's not GE90, it's PW4000-112."

"PW4000-112?"

Not long ago, Xu Cang heard about this engine model, because the Boeing 787 will use an improved model of this engine in the future.However, it has nothing to do with the Boeing 787 at the moment.In Xu Cang's memory, some things happened in the combination of PW4000-112 and Boeing 777, and it was a concentrated flight accident.

Xu Cang seemed to be enlightened by the light of the engine that had been puzzled until now. He thought of a possibility, and shouted: "Not good!"

　There are too many pits dug ahead, and I feel that there is still a lot to write in this book. I knew I would not dig so many pits.
