Chapter 186 Embers of the Remnant Fire! (Please subscribe!)
In the small conference room on the first floor of the Erhai base, Yi Feng, Qin Xin and Si Linglong sat in this small conference room, continuing the matter of renting ARJ21.
Looking at the mottled wall, Yi Feng felt a little bit emotional: "You really don't look like an airline company here."
"The new base is already under construction, and it's in the open space downhill." Almost all the important people who came here felt a little bit emotional. Although Qin Xin didn't really care about it, it still got a little annoying after so many times.
Yi Feng withdrew his scrutiny gaze, hummed, and finally did not continue the decoration here, but glanced at Si Linglong: "Some time ago, I heard from the cabin department that you resigned, but I didn't expect you to come here What. Is there something at NUS that makes you feel uncomfortable?"
Si Linglong seems to have a good personal relationship with Yi Feng, but she can actually understand it.The biggest barrier between people has never been type, region, language, the biggest barrier is always class.People of the same class naturally have a certain degree of closeness. Si Linglong and Yi Feng obviously knew each other a long time ago.
Si Linglong grinned: "Brother Feng, there are some people at National University Airlines who know my identity, and they hang around me every day, which is very annoying, so I came here."
"Then you should have told me, instead of resigning without saying a word." Yi Feng showed a hint of displeasure.
"National University Airlines has a complicated relationship, so I won't make trouble for you." Si Linglong laughed.
Due to its special status, National Airline has gathered a large number of people with this special background.For example, it is best not to touch the beautiful flight attendant over there, because it may be the little lover of the company leader.And those flight attendants who don't look pretty, or even ugly, can't be touched, because these people have real power figures in their families.
Si Linglong can still act willfully in Muhua Airlines, but in Guoda Airlines, even Si Linglong has to be cautious.She was clear-headed, and she didn't want to involve Yi Feng, which was a wise choice.
Yi Feng pondered for a moment, and didn't say anything grandiose. If he said something like supporting you, it was basically acquiescing to Si Linglong's words.There is no way, National University Airlines, under the feet of the emperor, is so complicated.
"You come here, does your grandfather know?" Yi Feng didn't want to continue the topic that made him unhappy, and changed to a relatively easy one.
"Muhua's 737 was leased by Xu Cang and his grandfather, of course he knew I was here."
Yi Feng's eyes were fixed: "The old man came here specially? It seems that it's not just for the plane. Linglong, you have grown up, and the old man is getting anxious."
As soon as this remark came out, Qin Xin, who had been silent all this time, raised her eyebrows, and looked at the flushed Si Linglong strangely, thoughtfully.
"Okay, let's get down to business." Yi Feng didn't want Si Linglong to be too embarrassed, so he just tasted it and turned to Qin Xin: "Miss Qin, let's tell the truth. If you really have Muhua Airlines as a way out, I don't think so." Xu Cang will first mention the ARJ21 lease to us, so, can you speak frankly? Xu Cang is very smart, and everything he does is purposeful. Why didn’t he choose Muhua Airlines, but chose us?"
Although Yi Feng is young, he can see things very thoroughly, and he understands things right away.It's just that this tone made the atmosphere in the field a bit cold, and it seemed that Yi Feng was quite serious.
As a result, Si Linglong shut her mouth obediently, and she could not interrupt the rest of the content carelessly.
Qin Xin sat up slightly, and she was not timid in front of Yi Feng: "You are right, Muhua Airlines is indeed not a good choice. Xu Cang rented a 737 from Chairman Si because of some special relationship. It is the limit, and there will not be any substantial discounts for the subsequent rental of ARJ21."
Previously, what Qin Xin said about Si Linglong was of course a joke, but now she is speaking the truth.Xu Cang or the entire Erhai base has no deep friendship with Muhua Airlines.The convenience provided by Muhua Airlines is only an appropriate emotional investment based on the optimism for Xu Cang's future.
It means, I think you may develop very well in the future, and I don’t want to have a bad relationship with you, so I will show some sincerity that is irrelevant to my own side, such as agreeing to recruit Erhai Base in Muhua Aviation headquarters, such as agreeing to lease a 737 .
These measures are not a substantial payment for Muhua Airlines, but just a small price to prevent the possibility of some inconvenience in the future.
However, if you want to say how optimistic Muhua Airlines is to Xu Cang, it's not!There are too many uncertainties in the future, and there is no need to invest too much in some small probability things.
As long as you don't have a bad relationship with Xu Cang, you don't need to maintain an overly intimate relationship. This is the attitude of Muhua Airlines.
Qin Xin sees this problem clearly, so she remains pessimistic about whether Muhua Airlines will give discounts on the issue of ARJ21 lease.
In fact, whether it is the ten ARJ21s of Muhua Airlines or the twenty ARJ21s of Guoda Airlines, they are the same for the current Erhai base, and they cannot be rented.
Just like what Qin Xin told me just now, the Erhai base can accept the lease of up to five ARJ21s, and this is the limit.However, it was obvious that Xu Cang wanted more, so he had to use some other means.
"So, what do you guys mean? There is no money for leasing our company's planes, and we are not optimistic about the prospect of leasing planes from Muhua Airlines. Isn't this a project that is not feasible at all? Is Xu Cang playing with me? "Yi Feng was a little unhappy.After he heard Xu Cang's words, his mind was full of this matter for several days and nights, and he ran over from Hanjing on purpose, but he got this answer?
Just as Yi Feng's voice fell, a slim figure suddenly appeared outside the door, it turned out to be Lu Xiaoxiao from Shanhang.
Not long ago, Xu Cang made a special call to Lu Xiaoxiao.Ask her to help with a market analysis on the intra-provincial routes operated by ARJ21.Originally, Xu Cang thought that he needed to talk a lot, but Lu Xiaoxiao simply agreed.
Afterwards, Xu Cang asked Deng Wenjia to help. Using his personal relationship, Deng Wenjia persuaded Lu Xiaoxiao's leader to temporarily grant her a long vacation.Then, Lu Xiaoxiao came directly to Erhai Lake to collect data on the spot for market analysis.
Lu Xiaoxiao entered the small conference room and put a thick text in front of Yi Feng. She said seriously: "This is the market analysis in the province where ARJ21 is running. If you take a look, it may change."
Yi Feng glanced at Lu Xiaoxiao, then at Qin Xin, and finally picked up the market analysis done by Lu Xiaoxiao patiently.
In the beginning, Yi Feng was a little contemptuous, because market analysis is his professional field, and many market analyzes done by others are like waste paper in his eyes. It seems full of mistakes and omissions, which is simply suffering.
However, with the passage of time, Yi Feng gradually restrained his contempt, and he suddenly found that the market analysis was surprisingly good.
Qin Xin was not in a hurry either, she just waited quietly, waiting for Yi Feng to finish the market analysis.
After more than half an hour, Yi Feng finally put down the text of the market analysis, and he couldn't help sighing: "I haven't seen such a beautiful market analysis for a long time, and it's much better than mine. It is said that mountains are not high, but immortals are famous, although your side is a bit rough, but it is really full of talents."
"Boss Yi is over the top, but she's not an employee of ours, she's just here to help."
"Huh?" Yi Feng looked at Lu Xiaoxiao curiously: "Where do you work now? Are you a professional third-party market analysis company?"
Lu Xiaoxiao found a seat and sat down: "That's not true! To be precise, I'm helping Xu Cang. Have you looked carefully, is there any change in the prospect of ARJ21 running intra-provincial routes?"
"Hahaha! There is some improvement. In your market analysis, this will indeed be a good profit point. Of course, this is only good. The air ticket price you set is too low. This is a bottleneck. You break through No. The most important thing is that you can’t increase the price, otherwise you will lose the greatest competitiveness.” Yi Feng saw it very clearly: “Intra-provincial routes. Just this profit point, it is estimated that you can grow to a medium-sized The level of the airline company. If you have no new growth points, this is your ceiling. In fact, this is also normal. We have verified that ARJ21 operates short-haul regional flights. Only certain routes are profitable. At this point, the public’s acceptance of this aircraft is still not very high.”
Turning the topic around, Yi Feng smiled and said, "However, Xu Cang's ability to turn losses into profits from this old market model is not a small breakthrough. Of course, this is not limited to this."
"That's all, why do I feel that you didn't read my analysis carefully?" Lu Xiaoxiao said: "Before, I conducted a special market research on the tolerance of air ticket prices. For the price set not higher than [-] Strategy is actually not the upper limit. From the information I have investigated, [-] yuan per ticket is the upper limit acceptable to most people in this area. But why is it still priced at [-] yuan instead of Four hundred? If the average price is set at four hundred, then the profit will increase, why not do that?"
Yi Feng instinctively sensed a question: "What do you mean?"
Qin Xin said with a smile: "Those contents belong to our commercial secrets, so it's hard to tell Mr. Yi. However, I can assure you that our profit margins are bigger than what you described in the market analysis in your hand." Double."
"Miss Qin, just based on your words, the profit margin will be doubled. There is no reason in the world, is there?" Although Yi Feng said so, he felt as uncomfortable as a cat's paw scratching in his heart. He was eager to know What is the profit strategy here.
Qin Xin sighed: "Mr. Yi, I also explained to you just now that we have no money to buy twenty ARJ21s. But why did Xu Cang propose such a cooperation? Because he wants to do this, he is very urgent. Actually In terms of development, we can do it steadily, instead of taking such a risk and directly eating twenty ARJ21s. The domestic market is huge, and you only look at the mid-to-high-end market, and you can’t let go of your figure, and those markets that you don’t like are enough to feed us. Be full."
"Then why do you do this?" Just from this market analysis, Yi Feng can see that there is not only one concept of operating the sinking market, but a relatively systematic business strategy.
As Qin Xin said, domestic airlines now have huge strategic inertia, and psychologically they dare not lower their brand standards to cater to the sinking market.Therefore, for a long time, the sinking market will be Xu Cang's blue ocean.
As long as we act steadily, the prospects will be very good, and we will not take much risk.
But Xu Cang still chooses to take the risk, even though there is a bright road in front of him.Twenty ARJ21s is a huge gamble for this nascent airline company.
Although Lu Xiaoxiao's market analysis is very good, there is still a certain probability that something unexpected will happen.If the operation of these 21 ARJ[-]s overturned, it would be a dead end with no chance of turning over.
But if only five are leased, although the profit growth will be slower, it is better to turn around because the boat is small.When it goes well, you can accumulate experience, and if there is an accident, you can stop the loss in time.
This time I was the best choice!
However, no matter in terms of words or demeanor, Yi Feng felt that he really wanted to eat twenty ARJ21s in one bite. He really couldn't figure out why he would take such an arbitrary risk.
Qin Xin smiled, and there was actually a hint of doting in the smile: "Because Xu Cang wants to buy something. It is very expensive, very expensive. If we operate stably, within seven years, the wealth we have accumulated will not be able to meet Xu Cang's requirements. Mr. Yi , we don’t have the money to lease these 21 ARJ[-]s, we only have shares. If Mr. Yi does not dislike it, we are willing to let National University Airlines join us in the form of aircraft shares.”
"You are empty-handed white wolves! Your current shares are worthless at all! No, those twenty ARJ21s are worth more than all of your current net worth." Yi Feng's expression sank all of a sudden.This is clearly a bet on the future of the Erhai base.
If this place can soar into the sky in the future, then these shares will be of infinite value.But if there is no growth here, then the investment in these 21 ARJ[-]s will be lost.
However, if it only grows into a medium-sized airline, it will not be very profitable.But if what Qin Xin said is true, and their actual profit margin is twice as large as the market analysis, then this aircraft investment will be very promising.
"Miss Qin, you really gave me a problem." Yi Feng didn't immediately refuse, but it actually represented a lot.However, he changed the subject and his expression became extremely solemn: "But, compared to this question, I want to know what Xu Cang wants to buy! Seven years, why is there a limit of seven years, what does this mean!?"
At this moment, in the cockpit of British Airways Flight 1009, the captain's forehead was already sweating.He wiped his face with his right hand, and his palm was wet with sweat.
"Captain, is there a speed problem?" At this time, the co-pilot also realized the problem.Obviously, under the condition that the thrust and attitude of the aircraft remain unchanged, the speed of the aircraft continues to increase slowly, which is obviously abnormal.
In fact, even under the condition of constant thrust and constant attitude, since the external airflow cannot be absolutely uniform, it is understandable that there are some fluctuations in the airspeed of the aircraft.However, it is absolutely impossible to have a sustained and slow increase.
The strange thing is that the increase in the speed of the aircraft is a linear and uniform speed increase.If the speed of the aircraft increases under the influence of airflow, it is likely to behave as if it should be fast and slow.
However, it does not mean that the continuous increase in the speed of this type of aircraft must be abnormal, it is just a matter of probability.In actual flight operations, non-artificial speeding occasionally occurs.
And this situation usually occurs when turning, especially when turning at a large angle.Because at high altitudes, the wind speed outside the aircraft is usually quite large. If the aircraft makes a large turn, the wind direction the aircraft faces will change greatly in a short period of time.
For example, it is possible to change from tailwind directly to headwind, and wind speed changes of more than tens of knots may occur at every turn.In this way, under the influence of this external wind speed change, the indicated airspeed of the aircraft will temporarily increase by a huge amount with the thrust and attitude unchanged, so that the crew will overspeed due to carelessness.
It was based on this idea that when the captain realized that the airspeed of the aircraft had increased strangely, he first checked to see if there was a sudden and huge change in the wind direction and speed outside.There are real-time wind direction and wind speed changes on the integrated electronic display screen of the aircraft, which can be seen at a glance.
If it were only the effect of the wind, then the situation would be easier to deal with.Leave plenty of room to prevent the plane from overspeeding, and the rest is out of the question.
This big change in wind usually doesn't last long and should stabilize fairly quickly.
However, the wind information that the captain saw just now is that the outside wind is very stable, which is an extremely bad omen.Obviously, the co-pilot also thought of this section.
It was precisely because he understood the situation here that the co-pilot's already flustered state of mind was completely overwhelmed.
The captain swallowed a mouthful of saliva, and he glanced at the two CDUs who were both dead, and the muscles in his left hand holding the steering wheel began to twitch unconsciously.
"Forget about the flight management computer, just look at the airspeed on the standby instrument!" After a brief evaluation, the captain still felt that the issue of dealing with the airspeed was more urgent.
During this period of hesitation, the aircraft's Mach number had increased from .72 to .74.
"Oh oh oh!" The co-pilot was completely dependent on the command of the captain at this time, and he hurriedly lowered his head to look at the spare mechanical instrument: "Captain, there is no Mach display on the spare instrument!"
"You're in a daze, when did the backup instrument have a Mach number, you just report the indicated airspeed!" It can be seen that the co-pilot really panicked, and he could say such unprofessional words.
Generally speaking, the accuracy of the indicated airspeed drops to a relatively low level after the aircraft exceeds [-] feet.Above this altitude, crews habitually use the Mach number to indicate the speed of the aircraft.
However, due to technical reasons, the mechanical backup instrument cannot display the Mach number of the aircraft at a high altitude, and can only always display a relatively inaccurate indicated airspeed.
Reasonably speaking, this should be an extremely basic point of knowledge, but the co-pilot made a mistake in his panic.
The co-pilot wiped his chin with the back of his hand to hide his embarrassment.Soon, he reported a number, 290 eight knots!However, the captain saw that the indicated airspeed on the PFD had already exceeded 310 knots, and the gap between the two was a bit too much, and the worst thing was that the airspeed indication on the PFD was still increasing, and the difference would continue to increase with time .
The fingers of the captain's left hand kept shaking, revealing his extremely anxious heart. Now the plane is heading towards an unimaginable uncontrollable slide.
"So, let's deal with the unreliable airspeed first. Continue with the checklist, and continue from the source of unreliable airspeed data." The captain shouted.
"Okay!" The co-pilot was still looking for the checklist related to FMC failure, and now he started to turn back, looking for the checklist of unreliable airspeed.
During this period, it went from "inconsistent indicated airspeed or unreliable airspeed" to "unplanned stabilizer trim" to "FMC left/right failed" and back to "inconsistent indicated airspeed or unreliable airspeed".
The co-pilot felt that he was either reading the checklist again, or was on the way to find the checklist.Even if you do simulated failure training, there will be no such complicated superimposed items.
He firmly remembered that neither the training program of the airline company nor the training recommendations of Boeing headquarters allowed overlapping items, that is to say, two completely unrelated faults could not be combined together.
According to Boeing's philosophy, Boeing aircraft are very safe.The probability of combined faults is very, very small, and there is no need for training.
Previously, he regarded Boeing's concept as a standard. If a Boeing aircraft can experience failures of two different systems at the same time, it means that this aircraft is not good, so the superimposed combination of failure training is a waste of time.
But now, if he can see the top executives of Boeing, he won't have to point at that person's nose and curse, what kind of shitty plane is your family?
It was precisely because he had not received training on superimposed faults that the co-pilot had obviously reached the limit of pressure he could bear, and began to make some low-level mistakes that shouldn't have been made.
However, fortunately, after going through the checklist "Inconsistent or Unreliable Indicated Airspeed", he finally found that checklist after a short period of time.
"Unable to determine a reliable source of airspeed data, maintain normal thrust and attitude for this phase of flight, refer to flight charts for unreliable airspeeds."
The captain looked at the airspeed that was about to reach the lower end of the red-black speed band, and his heart was beating wildly.After the co-pilot finished reading, he reacted for a full two seconds before waking up like a dream: "Check the watch, what should be the current altitude attitude and thrust."
Since the airspeed of the plane is unbelievable, we can only rely on proper attitude and thrust to keep the plane in a normal level flight state.
"Check the meter?" The co-pilot's lips were trembling, and his face was full of bewilderment.
The captain now focuses almost all his energy on the airspeed, but tilted his head slightly: "That's right, the flight charts for unreliable airspeeds should be in the flight performance chapter."
"Oh oh oh." The co-pilot suddenly realized, and hurried to the end of the checklist, still muttering: "Performance, performance."
However, from looking through the checklist calmly at the beginning, now his right hand has started to tremble, and the co-pilot is already about to collapse.
After finally turning to the flight performance chapter, but when he saw the index in the performance chapter, he immediately became dizzy.
He can't read the index of the flight performance chapter!
That's right, it's been more than five months since he last flipped through this chapter, and last time he only flipped through the brake cooling table.In other words, since the beginning of his career, he seems to have only found a flight chart with unreliable airspeed once, and it was in a leisurely, relaxed, and time-free situation.
In this situation, how does he remember how he found it before?
pat!
A bead of sweat from the co-pilot dripped onto the paper of the checklist, and this movement was caught by the nervous captain.The captain just glanced at the co-pilot quickly, seeing that he didn't move, and hurriedly reminded: "Looking for it, what are you doing?"
Just as the captain was urging, the controller's voice suddenly sounded on the radio: "British Airways 1009, your current position is about to deviate from the range of three nautical miles to the right of the route."
"Jesus Christ!" The captain gritted his teeth tightly. At this juncture, the plane's navigation unexpectedly went wrong again.No way, now that both flight management computers have failed, they can only fly using conventional instruments.Or, to be precise, they can only maintain one heading now.
However, the existence of crosswinds kept blowing the aircraft away from the planned route.Originally, in the captain's plan, even if there was wind, it would take a long time to blow them away from three nautical miles. After the control and contact with the airport were confirmed, they began to return under the guidance of radar. up.
However, man's calculation is not as good as heaven's calculation, and the influence of the crosswind is far stronger than he expected.It didn't take long before the plane was about to miss three nautical miles.
"Jakarta, now there is a reply from Soekarno-Hatta Airport, can we return?" The captain's first concern was this.Up to now, he no longer has the confidence to continue flying. He doesn't care whether it's overtime or not. He wants to return to the ground now.
"Wait a minute, our application has been sent." The controller said: "British Airways 1009, since you have navigation problems, please apply for a heading, but you can only fly west."
"Then the heading is 270." The captain said a heading casually.
"British Airways 1009, heading 270, agreed!" Jakarta control added another sentence: "British Airways 1009, do you plan to declare an emergency?"
The captain, who was already in a state of explosion, was furious when he heard what the controller said, "No need! Just let me go back, as soon as possible, as soon as possible!"
Perhaps the captain did not expect such a violent reaction, and the controller was a little frightened, and hurriedly said: "I got it, I got it! Wait a moment!"
At this moment, the captain, who was gradually becoming irritable, saw that the co-pilot had not been found, and immediately cursed: "Can you find it?"
"Hurry up, hurry up!" The co-pilot was sweating profusely.He no longer studied the index temporarily. Since he couldn't understand it, he didn't read it, and just turned back page by page from the beginning of the chapter.
Fortunately, the chapter on flight performance is just an independent chapter with not so much content.Although it is a bit stupid to do so, it is at least a feasible way.
However, from maximum climb EPR to reference speed, from normal configuration distance table to abnormal configuration landing distance table, from maximum continuous EPR with one engine inoperative, drift-down/level-off speed, long-range cruise altitude capability, From the remote cruise control to the fuel time of remote cruise diversion, the landing gear is lowered, and the landing gear is lowered plus one engine does not work.
The co-pilot was almost at the end of the roll, with more and more beads of sweat on his face, but he couldn't find the flight chart with unreliable airspeed.
The captain couldn't wait any longer, he held the steering wheel with his left hand, moved his right hand away from the thrust handle, and stretched towards the co-pilot: "Give it to me, I'll find it!"
The co-pilot was about to put the checklist on the captain's right hand, but before he started to move, the beeping overspeed warning sounded.
The captain withdrew his right hand like a conditioned reflex, and his first thought was to reduce the throttle.However, at the moment when this thought came into being, he realized that the airspeed was unreliable at the moment, and the overspeed warning might be false.
However, the airspeed indicators on the PFDs on both sides showed that the speed of the aircraft had indeed reached the red and black speed bands.
Although there is a high probability that the airspeeds on the two PFDs should be wrong, it is speculated that the overspeed warning should also be a false warning, just ignore it.But what if the airspeed on the PFD is actually correct?What if the plane is indeed speeding?
Of course, short-term, small-scale overspeed usually does not cause excessive structural damage.But you must know that the speed of the plane is still rising. If it exceeds too much, who knows what will happen?
So, the captain lowered his head and checked the speed of the backup instrument himself.At this moment, on the standby instrument, the speed of the plane has reached 320 knots, which is actually approaching the limit speed.
"Captain, do you ignore the speeding warning?" The co-pilot listened to the speeding warning in his ear, feeling irritable and scared at the same time.
The captain is also in a state of disarray at the moment, this is what he is most afraid of.It is impossible for any pilot to face the inability to determine the correct airspeed data. This is more troublesome than any control failure.
However, the speed on the PFD is already overspeed, and the speed on the standby instrument is also fast. No matter which speed is correct, the aircraft is already facing or will soon face the danger of overspeeding, so proper deceleration is definitely necessary.
However, since the co-pilot can't find out the thrust and attitude settings in this situation, the captain's deceleration action is actually somewhat risky.
However, the captain of Huashan Road still planned to do something.Under anxiety, people always tend to do something, even if he knows it may not be right.
Therefore, while maintaining the attitude of the aircraft, the captain retracted the throttle slightly, which was really a very small amount.This shows that the captain is still a little rational now.His idea is not radical, as long as the airspeed is slightly reduced, it is tolerable if the speed does not increase if it is not possible.
I don't know if the captain's response played a role. The speed of both the instruments on the PFD and the backup instruments seemed to have stopped.Although the overspeed warning was still sounding, the captain was overjoyed when he saw such a change: "That's it, that's it!"
It stands to reason that at this time the captain should hand over the plane to the co-pilot and let him find the flight chart of the unreliable airspeed.However, at this moment, the captain doesn't trust the co-pilot much anymore. At least from the current point of view, not to mention solving the fault, it is possible to maintain the status quo.
Therefore, the captain turned his head and wondered whether he could put aside the airspeed problem that he thought had been temporarily controlled, and try to solve the fault of the flight management computer first.
However, the captain no longer expected the co-pilot to find the checklist by himself, and he began to direct the co-pilot: "Landing switch man position, reset the altitude of Soekarno-Hatta Airport."
The co-pilot didn't understand what the captain was talking about for a while, but he had one advantage, that is, he was obedient.If you know you don't understand, then listen to the captain's instructions.
Therefore, the co-pilot immediately reset the landing altitude switch.Then the captain pointed to the center wing fuel tank switch: "Both are all turned off."
Without even thinking about it, the co-pilot directly closed all the center wing fuel tanks.But after doing this, the co-pilot hesitated for a while, and asked: "Captain, can you do the checklist of "Central Fuel Override"?"
"Don't do it!" The captain almost shouted. At this time, the co-pilot was not only unable to help, but also hindered him and created difficulties.
Soon, the captain felt that the plane was relatively stable, so he still handed over the plane to the co-pilot, who had to free his hands to find the flight chart of the unreliable airspeed.
Fortunately, the captain's judgment was correct. At this moment, the airflow around the plane has been relatively stable, and the co-pilot only needs a very small amount of input to maintain the stability of the plane.
After the co-pilot took over the control, the captain's left hand did not leave the steering wheel.He put the checklist on his knee and rummaged through it with his right hand alone.
However, the captain saw that the co-pilot seemed to be able to maintain the state of the plane, and distracted his attention a little bit, intending to find out the chart as soon as possible. The moment the plane might have encountered turbulence, the plane suddenly rushed upwards, scaring the captain. Shout directly: "I manipulate!"
Then, the captain didn't wait for the co-pilot to hand over the controls, and started directly.
After waiting for a short while, the plane finally stabilized.The captain directly passed the checklist to the co-pilot, he really didn't dare to hand over the plane.
"If you look for it again, it's in the chapter on flight performance anyway. You can't find it if you flip through it page by page?" the captain shouted.
In fact, the captain himself was not very familiar with this chart.The main reason is that he did not do much on the subject of unreliable airspeed. This subject is too complicated, and there are many things that are unclear, so try to avoid such controversial subjects during training, so that the captain himself is not very familiar with it. Know where that chart is.
After the captain took over the control of the plane and stabilized for less than ten seconds, the plane rushed again without warning, and this turbulence was very strange, it only lasted for a while, and the plane stopped immediately after the turbulence.
The captain is now thinking about the flight charts of unreliable airspeeds in his mind, and has not paid special attention to the phenomenon of the aircraft's continuous upward rush, only thinking that it is a problem of turbulent airflow.
While he was busy in the cockpit, Xu Cang looked at the hairs on his arms that stood up for no reason, and suddenly felt a little uneasy in his heart.
Suddenly, a first-class passenger behind Xu Cang pressed the flight attendant call bell.For first-class service, it is definitely on call.Almost as soon as the bell stopped, the purser came out of the front cabin work room.
The purser came over and turned off the call bell, and asked softly, "Sir, is there anything I can help you with?"
"Is there any strange smell on your plane? Didn't you clean it up? Since 10 minutes ago, I smelled some strange smell, or did you put some living things in the cargo hold?" The first-class passenger asked. It's still polite, and it's also polite to speak.
Because the cargo compartment and the passenger compartment are connected, most of the time due to the pressure difference, the gas in the cargo compartment will not flow to the passenger compartment.But in some cases, some strange smells in the cargo hold will be exhausted into the passenger cabin through the air conditioning system, especially when the cargo hold is loaded with living things.
The purser sniffed it himself, but he didn't seem to smell anything, so he replied softly: "Sir, as far as I know, we didn't carry any living things this time."
"But this smell is really strange, it's getting stronger and stronger."
The purser thought for a while: "Sir, let me ask the cockpit to confirm?"
Under normal circumstances, if the aircraft transports live animals, the cargo personnel will have a special captain's notice to the crew.
"Well, go and react." This man was easy to talk, and he didn't make things difficult for the purser at all.
"Sir, it may be high-altitude ozone." The chief purser suddenly thought of a possibility: "Sometimes, we can smell a special smell when we are flying, a bit like fishy smell, that is the smell of ozone. Now we The flying altitude is relatively high, and sometimes ozone can be smelled, especially when there is a thunderstorm nearby. I saw that the weather was not very good before taking off today, which may be the reason.”
Ozone content is relatively high in high-altitude environments, and it is understandable that ozone enters the cabin through the bleed air system.As for the thunderstorm environment, it is because during thunderstorms, lightning will ionize oxygen, thus forming more ozone.
What the purser said is actually correct, but it is not known whether it is applicable to the present.
The passenger was obviously moved by the purser, and he said to himself: "Ozone? But, what I smell doesn't seem to be fishy?"
"It's not fishy, what is that?" The purser was taken aback.
The passenger himself couldn't figure it out: "I can't describe it clearly either. Anyway, you should ask the cockpit to see if it's the cargo hold."
"Okay!" The purser stopped talking, and returned to the front cabin work room as he said.
However, these words were overheard by Xu Cang. He sniffed vigorously, and after careful identification, he could smell some pungent smell faintly.
In fact, he didn't know what it smelled like, it was so strange, as if he had never smelled it before.However, as a pilot, Xu Cang is familiar with the smell of ozone, and this is definitely not the smell of ozone.
"What's going on, what's going on?" Xu Cang became more and more uneasy, even he couldn't tell what made him feel uneasy.
Suddenly, Xu Cang trembled all over, and then his body stopped still like a sculpture.Faintly, he seemed to hear a little strange noise.
Boom!Boom!Boom!
It seems to be beating a drum, it seems to be breathing, and it seems to overlap with Xu Cang's heartbeat.
"What is this? Is it my illusion?" The voice was so small that Xu Cang couldn't be sure if he heard it wrong.
Suddenly, the plane bumped, which was a fairly normal experience, as it would be when encountering turbulence during flight.But Xu Cang's face turned pale in an instant, because the turbulence of the plane just now seemed to coincide with some strange frequency he had heard.
"No, no, I heard it right!" Xu Cang looked back suddenly, the voice came from the back of the plane.
Leo noticed Xu Cang's movements, and asked a little strangely: "Mr. Xu, what's wrong with you?"
Xu Cang made a silent movement, turned his ears sideways, and listened to the subtle sound.
At this time, even Song Xinyang next to him noticed something strange about Xu Cang.However, after seeing Xu Cang's silence, he wisely did not speak.
Boom!
After waiting for a while, the voice appeared again.And as if in response to the sound, the plane bumped again.At this moment, Xu Cang took a breath, gritted his teeth and said softly, "Damn it, the engine is surging!"
At this moment, Xu Cang no longer hesitated, his intuition was correct, something happened indeed.Moreover, what made Xu Cang feel even more worried was that when he noticed the engine surge, he also noticed that the sound of the engine running did not decrease at the same time, that is to say, there was no movement of closing the throttle in the cockpit. Procedures for dealing with engine surge.
Xu Cang immediately turned to Leo: "Take me into the cockpit!"
Leo didn't expect Xu Cang to ask to enter the cockpit at this time, and he was a little nervous for a while, and he could see that Xu Cang's expression was not right, so, as if he was infected by Xu Cang, Leo also became Panic: "Now?"
"That's right, it's now, hurry up!" Xu Cang growled.
Originally, he thought that the handling of the air crash was easy and the risks were controllable. After all, he had information from the future and knew when and why the plane crashed.But now, everything has changed, and it has become beyond his control.
In any case, it seems that the situation has not developed to the worst, and all dangers must be contained.
Leo pursed his lips for a moment, he could feel Xu Cang's urgency.This person is worthy of being an executive, and his psychological quality is still good. He immediately began to unbuckle his seat belt: "Mr. Xu, let's go to the front cabin first!"
Xu Cang nodded, and began to unbuckle his seat belt.While moving, Xu Cang was still listening to the sound of the engine surge outside. The only thing that made Xu Cang feel at ease was that the frequency of the engine surge was very low, and it didn't seem that serious.
But the moment Xu Cang unbuckled the seat belt, the low-frequency and low-volume surge suddenly rose without warning!
Boom!
The movement seemed to be the most tragic explosion in a closed iron barrel!The sudden explosion could be heard throughout the cabin!
Xu Cang stood up abruptly. He was really afraid of something. Just a moment ago, he was thankful that his surge was under control. Why is it deteriorating so fast now?
However, the moment Xu Cang stood up, he felt something in his heart. Under the light of the reading lamp, Xu Cang clearly saw countless fine dust falling down. They were so tiny that he didn't even notice them just now.
Xu Cangping raised his right palm, trying to catch the dust that came from nowhere.The dust is really too small, even if Xu Cang inherited it, they still cannot be seen with the naked eye.
Suddenly, Xu Cang's eyes narrowed slightly, and the falling dust seemed to have a ripple in his heart.
"This is not dust, this is ashes?" Xu Cang's heart was beating wildly, and the uncontrollable speed seemed to make his heart jump out of his throat.
Did he finally know what that strange smell was?
It's not ozone, it's sulfur!
(End of this chapter)
In the small conference room on the first floor of the Erhai base, Yi Feng, Qin Xin and Si Linglong sat in this small conference room, continuing the matter of renting ARJ21.
Looking at the mottled wall, Yi Feng felt a little bit emotional: "You really don't look like an airline company here."
"The new base is already under construction, and it's in the open space downhill." Almost all the important people who came here felt a little bit emotional. Although Qin Xin didn't really care about it, it still got a little annoying after so many times.
Yi Feng withdrew his scrutiny gaze, hummed, and finally did not continue the decoration here, but glanced at Si Linglong: "Some time ago, I heard from the cabin department that you resigned, but I didn't expect you to come here What. Is there something at NUS that makes you feel uncomfortable?"
Si Linglong seems to have a good personal relationship with Yi Feng, but she can actually understand it.The biggest barrier between people has never been type, region, language, the biggest barrier is always class.People of the same class naturally have a certain degree of closeness. Si Linglong and Yi Feng obviously knew each other a long time ago.
Si Linglong grinned: "Brother Feng, there are some people at National University Airlines who know my identity, and they hang around me every day, which is very annoying, so I came here."
"Then you should have told me, instead of resigning without saying a word." Yi Feng showed a hint of displeasure.
"National University Airlines has a complicated relationship, so I won't make trouble for you." Si Linglong laughed.
Due to its special status, National Airline has gathered a large number of people with this special background.For example, it is best not to touch the beautiful flight attendant over there, because it may be the little lover of the company leader.And those flight attendants who don't look pretty, or even ugly, can't be touched, because these people have real power figures in their families.
Si Linglong can still act willfully in Muhua Airlines, but in Guoda Airlines, even Si Linglong has to be cautious.She was clear-headed, and she didn't want to involve Yi Feng, which was a wise choice.
Yi Feng pondered for a moment, and didn't say anything grandiose. If he said something like supporting you, it was basically acquiescing to Si Linglong's words.There is no way, National University Airlines, under the feet of the emperor, is so complicated.
"You come here, does your grandfather know?" Yi Feng didn't want to continue the topic that made him unhappy, and changed to a relatively easy one.
"Muhua's 737 was leased by Xu Cang and his grandfather, of course he knew I was here."
Yi Feng's eyes were fixed: "The old man came here specially? It seems that it's not just for the plane. Linglong, you have grown up, and the old man is getting anxious."
As soon as this remark came out, Qin Xin, who had been silent all this time, raised her eyebrows, and looked at the flushed Si Linglong strangely, thoughtfully.
"Okay, let's get down to business." Yi Feng didn't want Si Linglong to be too embarrassed, so he just tasted it and turned to Qin Xin: "Miss Qin, let's tell the truth. If you really have Muhua Airlines as a way out, I don't think so." Xu Cang will first mention the ARJ21 lease to us, so, can you speak frankly? Xu Cang is very smart, and everything he does is purposeful. Why didn’t he choose Muhua Airlines, but chose us?"
Although Yi Feng is young, he can see things very thoroughly, and he understands things right away.It's just that this tone made the atmosphere in the field a bit cold, and it seemed that Yi Feng was quite serious.
As a result, Si Linglong shut her mouth obediently, and she could not interrupt the rest of the content carelessly.
Qin Xin sat up slightly, and she was not timid in front of Yi Feng: "You are right, Muhua Airlines is indeed not a good choice. Xu Cang rented a 737 from Chairman Si because of some special relationship. It is the limit, and there will not be any substantial discounts for the subsequent rental of ARJ21."
Previously, what Qin Xin said about Si Linglong was of course a joke, but now she is speaking the truth.Xu Cang or the entire Erhai base has no deep friendship with Muhua Airlines.The convenience provided by Muhua Airlines is only an appropriate emotional investment based on the optimism for Xu Cang's future.
It means, I think you may develop very well in the future, and I don’t want to have a bad relationship with you, so I will show some sincerity that is irrelevant to my own side, such as agreeing to recruit Erhai Base in Muhua Aviation headquarters, such as agreeing to lease a 737 .
These measures are not a substantial payment for Muhua Airlines, but just a small price to prevent the possibility of some inconvenience in the future.
However, if you want to say how optimistic Muhua Airlines is to Xu Cang, it's not!There are too many uncertainties in the future, and there is no need to invest too much in some small probability things.
As long as you don't have a bad relationship with Xu Cang, you don't need to maintain an overly intimate relationship. This is the attitude of Muhua Airlines.
Qin Xin sees this problem clearly, so she remains pessimistic about whether Muhua Airlines will give discounts on the issue of ARJ21 lease.
In fact, whether it is the ten ARJ21s of Muhua Airlines or the twenty ARJ21s of Guoda Airlines, they are the same for the current Erhai base, and they cannot be rented.
Just like what Qin Xin told me just now, the Erhai base can accept the lease of up to five ARJ21s, and this is the limit.However, it was obvious that Xu Cang wanted more, so he had to use some other means.
"So, what do you guys mean? There is no money for leasing our company's planes, and we are not optimistic about the prospect of leasing planes from Muhua Airlines. Isn't this a project that is not feasible at all? Is Xu Cang playing with me? "Yi Feng was a little unhappy.After he heard Xu Cang's words, his mind was full of this matter for several days and nights, and he ran over from Hanjing on purpose, but he got this answer?
Just as Yi Feng's voice fell, a slim figure suddenly appeared outside the door, it turned out to be Lu Xiaoxiao from Shanhang.
Not long ago, Xu Cang made a special call to Lu Xiaoxiao.Ask her to help with a market analysis on the intra-provincial routes operated by ARJ21.Originally, Xu Cang thought that he needed to talk a lot, but Lu Xiaoxiao simply agreed.
Afterwards, Xu Cang asked Deng Wenjia to help. Using his personal relationship, Deng Wenjia persuaded Lu Xiaoxiao's leader to temporarily grant her a long vacation.Then, Lu Xiaoxiao came directly to Erhai Lake to collect data on the spot for market analysis.
Lu Xiaoxiao entered the small conference room and put a thick text in front of Yi Feng. She said seriously: "This is the market analysis in the province where ARJ21 is running. If you take a look, it may change."
Yi Feng glanced at Lu Xiaoxiao, then at Qin Xin, and finally picked up the market analysis done by Lu Xiaoxiao patiently.
In the beginning, Yi Feng was a little contemptuous, because market analysis is his professional field, and many market analyzes done by others are like waste paper in his eyes. It seems full of mistakes and omissions, which is simply suffering.
However, with the passage of time, Yi Feng gradually restrained his contempt, and he suddenly found that the market analysis was surprisingly good.
Qin Xin was not in a hurry either, she just waited quietly, waiting for Yi Feng to finish the market analysis.
After more than half an hour, Yi Feng finally put down the text of the market analysis, and he couldn't help sighing: "I haven't seen such a beautiful market analysis for a long time, and it's much better than mine. It is said that mountains are not high, but immortals are famous, although your side is a bit rough, but it is really full of talents."
"Boss Yi is over the top, but she's not an employee of ours, she's just here to help."
"Huh?" Yi Feng looked at Lu Xiaoxiao curiously: "Where do you work now? Are you a professional third-party market analysis company?"
Lu Xiaoxiao found a seat and sat down: "That's not true! To be precise, I'm helping Xu Cang. Have you looked carefully, is there any change in the prospect of ARJ21 running intra-provincial routes?"
"Hahaha! There is some improvement. In your market analysis, this will indeed be a good profit point. Of course, this is only good. The air ticket price you set is too low. This is a bottleneck. You break through No. The most important thing is that you can’t increase the price, otherwise you will lose the greatest competitiveness.” Yi Feng saw it very clearly: “Intra-provincial routes. Just this profit point, it is estimated that you can grow to a medium-sized The level of the airline company. If you have no new growth points, this is your ceiling. In fact, this is also normal. We have verified that ARJ21 operates short-haul regional flights. Only certain routes are profitable. At this point, the public’s acceptance of this aircraft is still not very high.”
Turning the topic around, Yi Feng smiled and said, "However, Xu Cang's ability to turn losses into profits from this old market model is not a small breakthrough. Of course, this is not limited to this."
"That's all, why do I feel that you didn't read my analysis carefully?" Lu Xiaoxiao said: "Before, I conducted a special market research on the tolerance of air ticket prices. For the price set not higher than [-] Strategy is actually not the upper limit. From the information I have investigated, [-] yuan per ticket is the upper limit acceptable to most people in this area. But why is it still priced at [-] yuan instead of Four hundred? If the average price is set at four hundred, then the profit will increase, why not do that?"
Yi Feng instinctively sensed a question: "What do you mean?"
Qin Xin said with a smile: "Those contents belong to our commercial secrets, so it's hard to tell Mr. Yi. However, I can assure you that our profit margins are bigger than what you described in the market analysis in your hand." Double."
"Miss Qin, just based on your words, the profit margin will be doubled. There is no reason in the world, is there?" Although Yi Feng said so, he felt as uncomfortable as a cat's paw scratching in his heart. He was eager to know What is the profit strategy here.
Qin Xin sighed: "Mr. Yi, I also explained to you just now that we have no money to buy twenty ARJ21s. But why did Xu Cang propose such a cooperation? Because he wants to do this, he is very urgent. Actually In terms of development, we can do it steadily, instead of taking such a risk and directly eating twenty ARJ21s. The domestic market is huge, and you only look at the mid-to-high-end market, and you can’t let go of your figure, and those markets that you don’t like are enough to feed us. Be full."
"Then why do you do this?" Just from this market analysis, Yi Feng can see that there is not only one concept of operating the sinking market, but a relatively systematic business strategy.
As Qin Xin said, domestic airlines now have huge strategic inertia, and psychologically they dare not lower their brand standards to cater to the sinking market.Therefore, for a long time, the sinking market will be Xu Cang's blue ocean.
As long as we act steadily, the prospects will be very good, and we will not take much risk.
But Xu Cang still chooses to take the risk, even though there is a bright road in front of him.Twenty ARJ21s is a huge gamble for this nascent airline company.
Although Lu Xiaoxiao's market analysis is very good, there is still a certain probability that something unexpected will happen.If the operation of these 21 ARJ[-]s overturned, it would be a dead end with no chance of turning over.
But if only five are leased, although the profit growth will be slower, it is better to turn around because the boat is small.When it goes well, you can accumulate experience, and if there is an accident, you can stop the loss in time.
This time I was the best choice!
However, no matter in terms of words or demeanor, Yi Feng felt that he really wanted to eat twenty ARJ21s in one bite. He really couldn't figure out why he would take such an arbitrary risk.
Qin Xin smiled, and there was actually a hint of doting in the smile: "Because Xu Cang wants to buy something. It is very expensive, very expensive. If we operate stably, within seven years, the wealth we have accumulated will not be able to meet Xu Cang's requirements. Mr. Yi , we don’t have the money to lease these 21 ARJ[-]s, we only have shares. If Mr. Yi does not dislike it, we are willing to let National University Airlines join us in the form of aircraft shares.”
"You are empty-handed white wolves! Your current shares are worthless at all! No, those twenty ARJ21s are worth more than all of your current net worth." Yi Feng's expression sank all of a sudden.This is clearly a bet on the future of the Erhai base.
If this place can soar into the sky in the future, then these shares will be of infinite value.But if there is no growth here, then the investment in these 21 ARJ[-]s will be lost.
However, if it only grows into a medium-sized airline, it will not be very profitable.But if what Qin Xin said is true, and their actual profit margin is twice as large as the market analysis, then this aircraft investment will be very promising.
"Miss Qin, you really gave me a problem." Yi Feng didn't immediately refuse, but it actually represented a lot.However, he changed the subject and his expression became extremely solemn: "But, compared to this question, I want to know what Xu Cang wants to buy! Seven years, why is there a limit of seven years, what does this mean!?"
At this moment, in the cockpit of British Airways Flight 1009, the captain's forehead was already sweating.He wiped his face with his right hand, and his palm was wet with sweat.
"Captain, is there a speed problem?" At this time, the co-pilot also realized the problem.Obviously, under the condition that the thrust and attitude of the aircraft remain unchanged, the speed of the aircraft continues to increase slowly, which is obviously abnormal.
In fact, even under the condition of constant thrust and constant attitude, since the external airflow cannot be absolutely uniform, it is understandable that there are some fluctuations in the airspeed of the aircraft.However, it is absolutely impossible to have a sustained and slow increase.
The strange thing is that the increase in the speed of the aircraft is a linear and uniform speed increase.If the speed of the aircraft increases under the influence of airflow, it is likely to behave as if it should be fast and slow.
However, it does not mean that the continuous increase in the speed of this type of aircraft must be abnormal, it is just a matter of probability.In actual flight operations, non-artificial speeding occasionally occurs.
And this situation usually occurs when turning, especially when turning at a large angle.Because at high altitudes, the wind speed outside the aircraft is usually quite large. If the aircraft makes a large turn, the wind direction the aircraft faces will change greatly in a short period of time.
For example, it is possible to change from tailwind directly to headwind, and wind speed changes of more than tens of knots may occur at every turn.In this way, under the influence of this external wind speed change, the indicated airspeed of the aircraft will temporarily increase by a huge amount with the thrust and attitude unchanged, so that the crew will overspeed due to carelessness.
It was based on this idea that when the captain realized that the airspeed of the aircraft had increased strangely, he first checked to see if there was a sudden and huge change in the wind direction and speed outside.There are real-time wind direction and wind speed changes on the integrated electronic display screen of the aircraft, which can be seen at a glance.
If it were only the effect of the wind, then the situation would be easier to deal with.Leave plenty of room to prevent the plane from overspeeding, and the rest is out of the question.
This big change in wind usually doesn't last long and should stabilize fairly quickly.
However, the wind information that the captain saw just now is that the outside wind is very stable, which is an extremely bad omen.Obviously, the co-pilot also thought of this section.
It was precisely because he understood the situation here that the co-pilot's already flustered state of mind was completely overwhelmed.
The captain swallowed a mouthful of saliva, and he glanced at the two CDUs who were both dead, and the muscles in his left hand holding the steering wheel began to twitch unconsciously.
"Forget about the flight management computer, just look at the airspeed on the standby instrument!" After a brief evaluation, the captain still felt that the issue of dealing with the airspeed was more urgent.
During this period of hesitation, the aircraft's Mach number had increased from .72 to .74.
"Oh oh oh!" The co-pilot was completely dependent on the command of the captain at this time, and he hurriedly lowered his head to look at the spare mechanical instrument: "Captain, there is no Mach display on the spare instrument!"
"You're in a daze, when did the backup instrument have a Mach number, you just report the indicated airspeed!" It can be seen that the co-pilot really panicked, and he could say such unprofessional words.
Generally speaking, the accuracy of the indicated airspeed drops to a relatively low level after the aircraft exceeds [-] feet.Above this altitude, crews habitually use the Mach number to indicate the speed of the aircraft.
However, due to technical reasons, the mechanical backup instrument cannot display the Mach number of the aircraft at a high altitude, and can only always display a relatively inaccurate indicated airspeed.
Reasonably speaking, this should be an extremely basic point of knowledge, but the co-pilot made a mistake in his panic.
The co-pilot wiped his chin with the back of his hand to hide his embarrassment.Soon, he reported a number, 290 eight knots!However, the captain saw that the indicated airspeed on the PFD had already exceeded 310 knots, and the gap between the two was a bit too much, and the worst thing was that the airspeed indication on the PFD was still increasing, and the difference would continue to increase with time .
The fingers of the captain's left hand kept shaking, revealing his extremely anxious heart. Now the plane is heading towards an unimaginable uncontrollable slide.
"So, let's deal with the unreliable airspeed first. Continue with the checklist, and continue from the source of unreliable airspeed data." The captain shouted.
"Okay!" The co-pilot was still looking for the checklist related to FMC failure, and now he started to turn back, looking for the checklist of unreliable airspeed.
During this period, it went from "inconsistent indicated airspeed or unreliable airspeed" to "unplanned stabilizer trim" to "FMC left/right failed" and back to "inconsistent indicated airspeed or unreliable airspeed".
The co-pilot felt that he was either reading the checklist again, or was on the way to find the checklist.Even if you do simulated failure training, there will be no such complicated superimposed items.
He firmly remembered that neither the training program of the airline company nor the training recommendations of Boeing headquarters allowed overlapping items, that is to say, two completely unrelated faults could not be combined together.
According to Boeing's philosophy, Boeing aircraft are very safe.The probability of combined faults is very, very small, and there is no need for training.
Previously, he regarded Boeing's concept as a standard. If a Boeing aircraft can experience failures of two different systems at the same time, it means that this aircraft is not good, so the superimposed combination of failure training is a waste of time.
But now, if he can see the top executives of Boeing, he won't have to point at that person's nose and curse, what kind of shitty plane is your family?
It was precisely because he had not received training on superimposed faults that the co-pilot had obviously reached the limit of pressure he could bear, and began to make some low-level mistakes that shouldn't have been made.
However, fortunately, after going through the checklist "Inconsistent or Unreliable Indicated Airspeed", he finally found that checklist after a short period of time.
"Unable to determine a reliable source of airspeed data, maintain normal thrust and attitude for this phase of flight, refer to flight charts for unreliable airspeeds."
The captain looked at the airspeed that was about to reach the lower end of the red-black speed band, and his heart was beating wildly.After the co-pilot finished reading, he reacted for a full two seconds before waking up like a dream: "Check the watch, what should be the current altitude attitude and thrust."
Since the airspeed of the plane is unbelievable, we can only rely on proper attitude and thrust to keep the plane in a normal level flight state.
"Check the meter?" The co-pilot's lips were trembling, and his face was full of bewilderment.
The captain now focuses almost all his energy on the airspeed, but tilted his head slightly: "That's right, the flight charts for unreliable airspeeds should be in the flight performance chapter."
"Oh oh oh." The co-pilot suddenly realized, and hurried to the end of the checklist, still muttering: "Performance, performance."
However, from looking through the checklist calmly at the beginning, now his right hand has started to tremble, and the co-pilot is already about to collapse.
After finally turning to the flight performance chapter, but when he saw the index in the performance chapter, he immediately became dizzy.
He can't read the index of the flight performance chapter!
That's right, it's been more than five months since he last flipped through this chapter, and last time he only flipped through the brake cooling table.In other words, since the beginning of his career, he seems to have only found a flight chart with unreliable airspeed once, and it was in a leisurely, relaxed, and time-free situation.
In this situation, how does he remember how he found it before?
pat!
A bead of sweat from the co-pilot dripped onto the paper of the checklist, and this movement was caught by the nervous captain.The captain just glanced at the co-pilot quickly, seeing that he didn't move, and hurriedly reminded: "Looking for it, what are you doing?"
Just as the captain was urging, the controller's voice suddenly sounded on the radio: "British Airways 1009, your current position is about to deviate from the range of three nautical miles to the right of the route."
"Jesus Christ!" The captain gritted his teeth tightly. At this juncture, the plane's navigation unexpectedly went wrong again.No way, now that both flight management computers have failed, they can only fly using conventional instruments.Or, to be precise, they can only maintain one heading now.
However, the existence of crosswinds kept blowing the aircraft away from the planned route.Originally, in the captain's plan, even if there was wind, it would take a long time to blow them away from three nautical miles. After the control and contact with the airport were confirmed, they began to return under the guidance of radar. up.
However, man's calculation is not as good as heaven's calculation, and the influence of the crosswind is far stronger than he expected.It didn't take long before the plane was about to miss three nautical miles.
"Jakarta, now there is a reply from Soekarno-Hatta Airport, can we return?" The captain's first concern was this.Up to now, he no longer has the confidence to continue flying. He doesn't care whether it's overtime or not. He wants to return to the ground now.
"Wait a minute, our application has been sent." The controller said: "British Airways 1009, since you have navigation problems, please apply for a heading, but you can only fly west."
"Then the heading is 270." The captain said a heading casually.
"British Airways 1009, heading 270, agreed!" Jakarta control added another sentence: "British Airways 1009, do you plan to declare an emergency?"
The captain, who was already in a state of explosion, was furious when he heard what the controller said, "No need! Just let me go back, as soon as possible, as soon as possible!"
Perhaps the captain did not expect such a violent reaction, and the controller was a little frightened, and hurriedly said: "I got it, I got it! Wait a moment!"
At this moment, the captain, who was gradually becoming irritable, saw that the co-pilot had not been found, and immediately cursed: "Can you find it?"
"Hurry up, hurry up!" The co-pilot was sweating profusely.He no longer studied the index temporarily. Since he couldn't understand it, he didn't read it, and just turned back page by page from the beginning of the chapter.
Fortunately, the chapter on flight performance is just an independent chapter with not so much content.Although it is a bit stupid to do so, it is at least a feasible way.
However, from maximum climb EPR to reference speed, from normal configuration distance table to abnormal configuration landing distance table, from maximum continuous EPR with one engine inoperative, drift-down/level-off speed, long-range cruise altitude capability, From the remote cruise control to the fuel time of remote cruise diversion, the landing gear is lowered, and the landing gear is lowered plus one engine does not work.
The co-pilot was almost at the end of the roll, with more and more beads of sweat on his face, but he couldn't find the flight chart with unreliable airspeed.
The captain couldn't wait any longer, he held the steering wheel with his left hand, moved his right hand away from the thrust handle, and stretched towards the co-pilot: "Give it to me, I'll find it!"
The co-pilot was about to put the checklist on the captain's right hand, but before he started to move, the beeping overspeed warning sounded.
The captain withdrew his right hand like a conditioned reflex, and his first thought was to reduce the throttle.However, at the moment when this thought came into being, he realized that the airspeed was unreliable at the moment, and the overspeed warning might be false.
However, the airspeed indicators on the PFDs on both sides showed that the speed of the aircraft had indeed reached the red and black speed bands.
Although there is a high probability that the airspeeds on the two PFDs should be wrong, it is speculated that the overspeed warning should also be a false warning, just ignore it.But what if the airspeed on the PFD is actually correct?What if the plane is indeed speeding?
Of course, short-term, small-scale overspeed usually does not cause excessive structural damage.But you must know that the speed of the plane is still rising. If it exceeds too much, who knows what will happen?
So, the captain lowered his head and checked the speed of the backup instrument himself.At this moment, on the standby instrument, the speed of the plane has reached 320 knots, which is actually approaching the limit speed.
"Captain, do you ignore the speeding warning?" The co-pilot listened to the speeding warning in his ear, feeling irritable and scared at the same time.
The captain is also in a state of disarray at the moment, this is what he is most afraid of.It is impossible for any pilot to face the inability to determine the correct airspeed data. This is more troublesome than any control failure.
However, the speed on the PFD is already overspeed, and the speed on the standby instrument is also fast. No matter which speed is correct, the aircraft is already facing or will soon face the danger of overspeeding, so proper deceleration is definitely necessary.
However, since the co-pilot can't find out the thrust and attitude settings in this situation, the captain's deceleration action is actually somewhat risky.
However, the captain of Huashan Road still planned to do something.Under anxiety, people always tend to do something, even if he knows it may not be right.
Therefore, while maintaining the attitude of the aircraft, the captain retracted the throttle slightly, which was really a very small amount.This shows that the captain is still a little rational now.His idea is not radical, as long as the airspeed is slightly reduced, it is tolerable if the speed does not increase if it is not possible.
I don't know if the captain's response played a role. The speed of both the instruments on the PFD and the backup instruments seemed to have stopped.Although the overspeed warning was still sounding, the captain was overjoyed when he saw such a change: "That's it, that's it!"
It stands to reason that at this time the captain should hand over the plane to the co-pilot and let him find the flight chart of the unreliable airspeed.However, at this moment, the captain doesn't trust the co-pilot much anymore. At least from the current point of view, not to mention solving the fault, it is possible to maintain the status quo.
Therefore, the captain turned his head and wondered whether he could put aside the airspeed problem that he thought had been temporarily controlled, and try to solve the fault of the flight management computer first.
However, the captain no longer expected the co-pilot to find the checklist by himself, and he began to direct the co-pilot: "Landing switch man position, reset the altitude of Soekarno-Hatta Airport."
The co-pilot didn't understand what the captain was talking about for a while, but he had one advantage, that is, he was obedient.If you know you don't understand, then listen to the captain's instructions.
Therefore, the co-pilot immediately reset the landing altitude switch.Then the captain pointed to the center wing fuel tank switch: "Both are all turned off."
Without even thinking about it, the co-pilot directly closed all the center wing fuel tanks.But after doing this, the co-pilot hesitated for a while, and asked: "Captain, can you do the checklist of "Central Fuel Override"?"
"Don't do it!" The captain almost shouted. At this time, the co-pilot was not only unable to help, but also hindered him and created difficulties.
Soon, the captain felt that the plane was relatively stable, so he still handed over the plane to the co-pilot, who had to free his hands to find the flight chart of the unreliable airspeed.
Fortunately, the captain's judgment was correct. At this moment, the airflow around the plane has been relatively stable, and the co-pilot only needs a very small amount of input to maintain the stability of the plane.
After the co-pilot took over the control, the captain's left hand did not leave the steering wheel.He put the checklist on his knee and rummaged through it with his right hand alone.
However, the captain saw that the co-pilot seemed to be able to maintain the state of the plane, and distracted his attention a little bit, intending to find out the chart as soon as possible. The moment the plane might have encountered turbulence, the plane suddenly rushed upwards, scaring the captain. Shout directly: "I manipulate!"
Then, the captain didn't wait for the co-pilot to hand over the controls, and started directly.
After waiting for a short while, the plane finally stabilized.The captain directly passed the checklist to the co-pilot, he really didn't dare to hand over the plane.
"If you look for it again, it's in the chapter on flight performance anyway. You can't find it if you flip through it page by page?" the captain shouted.
In fact, the captain himself was not very familiar with this chart.The main reason is that he did not do much on the subject of unreliable airspeed. This subject is too complicated, and there are many things that are unclear, so try to avoid such controversial subjects during training, so that the captain himself is not very familiar with it. Know where that chart is.
After the captain took over the control of the plane and stabilized for less than ten seconds, the plane rushed again without warning, and this turbulence was very strange, it only lasted for a while, and the plane stopped immediately after the turbulence.
The captain is now thinking about the flight charts of unreliable airspeeds in his mind, and has not paid special attention to the phenomenon of the aircraft's continuous upward rush, only thinking that it is a problem of turbulent airflow.
While he was busy in the cockpit, Xu Cang looked at the hairs on his arms that stood up for no reason, and suddenly felt a little uneasy in his heart.
Suddenly, a first-class passenger behind Xu Cang pressed the flight attendant call bell.For first-class service, it is definitely on call.Almost as soon as the bell stopped, the purser came out of the front cabin work room.
The purser came over and turned off the call bell, and asked softly, "Sir, is there anything I can help you with?"
"Is there any strange smell on your plane? Didn't you clean it up? Since 10 minutes ago, I smelled some strange smell, or did you put some living things in the cargo hold?" The first-class passenger asked. It's still polite, and it's also polite to speak.
Because the cargo compartment and the passenger compartment are connected, most of the time due to the pressure difference, the gas in the cargo compartment will not flow to the passenger compartment.But in some cases, some strange smells in the cargo hold will be exhausted into the passenger cabin through the air conditioning system, especially when the cargo hold is loaded with living things.
The purser sniffed it himself, but he didn't seem to smell anything, so he replied softly: "Sir, as far as I know, we didn't carry any living things this time."
"But this smell is really strange, it's getting stronger and stronger."
The purser thought for a while: "Sir, let me ask the cockpit to confirm?"
Under normal circumstances, if the aircraft transports live animals, the cargo personnel will have a special captain's notice to the crew.
"Well, go and react." This man was easy to talk, and he didn't make things difficult for the purser at all.
"Sir, it may be high-altitude ozone." The chief purser suddenly thought of a possibility: "Sometimes, we can smell a special smell when we are flying, a bit like fishy smell, that is the smell of ozone. Now we The flying altitude is relatively high, and sometimes ozone can be smelled, especially when there is a thunderstorm nearby. I saw that the weather was not very good before taking off today, which may be the reason.”
Ozone content is relatively high in high-altitude environments, and it is understandable that ozone enters the cabin through the bleed air system.As for the thunderstorm environment, it is because during thunderstorms, lightning will ionize oxygen, thus forming more ozone.
What the purser said is actually correct, but it is not known whether it is applicable to the present.
The passenger was obviously moved by the purser, and he said to himself: "Ozone? But, what I smell doesn't seem to be fishy?"
"It's not fishy, what is that?" The purser was taken aback.
The passenger himself couldn't figure it out: "I can't describe it clearly either. Anyway, you should ask the cockpit to see if it's the cargo hold."
"Okay!" The purser stopped talking, and returned to the front cabin work room as he said.
However, these words were overheard by Xu Cang. He sniffed vigorously, and after careful identification, he could smell some pungent smell faintly.
In fact, he didn't know what it smelled like, it was so strange, as if he had never smelled it before.However, as a pilot, Xu Cang is familiar with the smell of ozone, and this is definitely not the smell of ozone.
"What's going on, what's going on?" Xu Cang became more and more uneasy, even he couldn't tell what made him feel uneasy.
Suddenly, Xu Cang trembled all over, and then his body stopped still like a sculpture.Faintly, he seemed to hear a little strange noise.
Boom!Boom!Boom!
It seems to be beating a drum, it seems to be breathing, and it seems to overlap with Xu Cang's heartbeat.
"What is this? Is it my illusion?" The voice was so small that Xu Cang couldn't be sure if he heard it wrong.
Suddenly, the plane bumped, which was a fairly normal experience, as it would be when encountering turbulence during flight.But Xu Cang's face turned pale in an instant, because the turbulence of the plane just now seemed to coincide with some strange frequency he had heard.
"No, no, I heard it right!" Xu Cang looked back suddenly, the voice came from the back of the plane.
Leo noticed Xu Cang's movements, and asked a little strangely: "Mr. Xu, what's wrong with you?"
Xu Cang made a silent movement, turned his ears sideways, and listened to the subtle sound.
At this time, even Song Xinyang next to him noticed something strange about Xu Cang.However, after seeing Xu Cang's silence, he wisely did not speak.
Boom!
After waiting for a while, the voice appeared again.And as if in response to the sound, the plane bumped again.At this moment, Xu Cang took a breath, gritted his teeth and said softly, "Damn it, the engine is surging!"
At this moment, Xu Cang no longer hesitated, his intuition was correct, something happened indeed.Moreover, what made Xu Cang feel even more worried was that when he noticed the engine surge, he also noticed that the sound of the engine running did not decrease at the same time, that is to say, there was no movement of closing the throttle in the cockpit. Procedures for dealing with engine surge.
Xu Cang immediately turned to Leo: "Take me into the cockpit!"
Leo didn't expect Xu Cang to ask to enter the cockpit at this time, and he was a little nervous for a while, and he could see that Xu Cang's expression was not right, so, as if he was infected by Xu Cang, Leo also became Panic: "Now?"
"That's right, it's now, hurry up!" Xu Cang growled.
Originally, he thought that the handling of the air crash was easy and the risks were controllable. After all, he had information from the future and knew when and why the plane crashed.But now, everything has changed, and it has become beyond his control.
In any case, it seems that the situation has not developed to the worst, and all dangers must be contained.
Leo pursed his lips for a moment, he could feel Xu Cang's urgency.This person is worthy of being an executive, and his psychological quality is still good. He immediately began to unbuckle his seat belt: "Mr. Xu, let's go to the front cabin first!"
Xu Cang nodded, and began to unbuckle his seat belt.While moving, Xu Cang was still listening to the sound of the engine surge outside. The only thing that made Xu Cang feel at ease was that the frequency of the engine surge was very low, and it didn't seem that serious.
But the moment Xu Cang unbuckled the seat belt, the low-frequency and low-volume surge suddenly rose without warning!
Boom!
The movement seemed to be the most tragic explosion in a closed iron barrel!The sudden explosion could be heard throughout the cabin!
Xu Cang stood up abruptly. He was really afraid of something. Just a moment ago, he was thankful that his surge was under control. Why is it deteriorating so fast now?
However, the moment Xu Cang stood up, he felt something in his heart. Under the light of the reading lamp, Xu Cang clearly saw countless fine dust falling down. They were so tiny that he didn't even notice them just now.
Xu Cangping raised his right palm, trying to catch the dust that came from nowhere.The dust is really too small, even if Xu Cang inherited it, they still cannot be seen with the naked eye.
Suddenly, Xu Cang's eyes narrowed slightly, and the falling dust seemed to have a ripple in his heart.
"This is not dust, this is ashes?" Xu Cang's heart was beating wildly, and the uncontrollable speed seemed to make his heart jump out of his throat.
Did he finally know what that strange smell was?
It's not ozone, it's sulfur!
