Chapter 317 The genius is on the left!The madman is on the right!
In a large conference room on the top floor of a high-end hotel near Munich Airport, senior executives of several major European airlines gathered together, discussing the increasingly prosperous European civil aviation industry driven by the issuance of the euro.
Among them are the presidents or chairman of internationally renowned airlines such as Air France, Lufthansa, KLM, and Alitalia.
In this small conference room, except for the representative of British Airways who did not come, almost [-]% of the European civil aviation forces were included.However, in addition to this, the focus of the meeting was a non-airline person, that is Richard, the president of the International Federation of Airline Pilots Association.
No one can ignore Richard's existence, but in the daily operation of the company, the International Federation of Airline Pilots Association does not interfere.Therefore, Richard has become indispensable, but rarely speaks in the meeting.
The level of this meeting is relatively high. After all, it brought together almost the entire civil aviation power in Europe. There must be many media reporters rushing to report on this level of business meeting. The cameras in the circle behind the participants and the Journalists are the best proof.
In any case, the content of the conversation in the meeting is to be made public.This kind of content that needs to be made public is cautious in words and deeds and lacks substantive content.The top executives of several companies just read the prepared and polished manuscripts in advance.
During the meeting, there were no quarrels, no verbal confrontation, and some just passed the air ahead of time, just like acting for a show.In this default state, everyone maintains their dignity as business elites.
The formal meeting lasted about an hour. After the host proposed a break at halftime, these elites who were sitting upright and meticulous immediately showed a relaxed posture, and some even chatted with the reporters around them, chatting Talk about the effects that might appear in the newspapers tomorrow.
The media personnel who can be invited are naturally screened, knowing what can be filmed and what cannot be filmed.During the halftime session, all the surrounding cameras were turned off sensibly, and a group of bigwigs from the airlines began to enjoy this rare time for chatting.
As the actual controller of the European civil aviation industry, this circle is very small, so these people basically know each other.Among them, the president of Royal Dutch Airlines saw Richard who was not interested, and asked with a smile: "Richard, I heard that Isiris is trapped in the Alps. Is there such a thing?"
It can be seen that the KLM president has a good personal relationship with Richard.Richard is called by a shortened nickname.
If the original plan had been followed, the vacation plan of British Airways President Isiris would have ended yesterday.Then, of course, I came to Munich by private helicopter, rested for one night, and attended the conference the next day without any delay.
Munich is close to the northern foothills of the Alps. Even a slower helicopter will not take too long, which is convenient.
However, as the Alps encountered a rare blizzard, representatives of British Airways were absent from the European Civil Aviation Conference.
Richard also works part-time as a technical consultant for British Airways, ask him is the best choice.
"You look very happy. Although I don't know why you are so happy, but if Isiris comes back and knows your reaction to this, the cooperation project between you and British Airways may be very dangerous." Reason Chad laughed.
"Richard, you're just so bored, spending some time at British Airways, don't you really think of yourself as a British Airways person?" The president of Royal Dutch Airlines smiled brightly: "And, if you really care about British Airways Airline. Then British Airways’ recent strikes wouldn’t be so drastic, would they?”
Compared with the slightly frivolous demeanor of the president of KLM, the president of Lufthansa is much more stable, just like the image of this old airline.
"Richard, with the launch of the euro, the European civil aviation market is overheated. We admit that airlines can grow considerably in it. However, we also hope that the unions will not have too much appetite. This is not for both parties. Good thing."
As soon as the president of Lufthansa Air Lines finished speaking, the chairman of Alitalia began to joke: "Didn't Lufthansa raise your salary a while ago? Why, the union is not satisfied now and wants to raise the salary again." ?”
The president of Lufthansa Airways kept silent and did not answer this question at all.
The chairman of Spain's national airline just sneered: "It deserves it!"
As soon as this remark came out, the president of Lufthansa immediately changed his face and slapped the table: "What did you say?"
"What did I say? I said that Lufthansa deserves what you deserve." The chairman of Iberia directly confronted: "You Lufthansa and Air France clearly know that European airlines will affect each other. In the end, they rushed up without telling us. The salary is 12.00%, which directly puts us in an embarrassing situation. That is, British Airways’ Isiris did not come, otherwise he is the one who scolds you now. As far as I know, the average salary increase of the British Airways union [-]%. Not long ago, our trade union asked us to ask for a [-]% salary increase. These are all good things you have done."
For things like salary increases, whoever takes the initiative to do so will take the initiative, and can raise salary at a smaller rate.However, this has caused other airlines to suffer.
The labor unions of the remaining airlines will directly refer to the previous wage increase standards when they follow up the strike, and then the chances are that the labor unions of the remaining airlines will increase their demands for salary increases. In terms of the performance of the union, it almost perfectly confirmed the idea of the chairman of the Spanish national airline.
Among them, the British Airways labor union has the greatest appetite, directly increasing the average salary increase by [-]%, which has brought a huge financial burden to British Airways.
These aviation bosses all know that in the current extremely hot market, salary increases are imperative.However, how to suppress the salary increase as much as possible when the labor market is dominant is what these big bosses need to consider.
In fact, the best way is for the leaders of major European airlines to reach an agreement on the salary increase in advance, and not to change it easily.
As long as all the companies are united and have a unified caliber, it will be easier to dismiss the trade union.
However, Lufthansa and Air France sold all the remaining airlines in order to seize the opportunity.
However, as the initiators of active salary increases, Lufthansa and Air France actually only received short-term benefits.
After betting on the mouths of their own unions with an average salary increase of [-]%, in recent days, the union representatives of Lufthansa and Air France, after learning that the wage increases of other companies' unions are generally more than [-]%, directly tore up The memorandum reached with the company also raised the salary increase by [-]%.
This makes the leadership of Lufthansa and Air France a buffoon.
In order to save some financial expenses for salary increases, it was at the cost of ruining his own reputation.In the end, the reputation is bad, but nothing has changed. What do the leadership of Lufthansa and Air France think?
The most important force in Richard's International Federation of Airline Pilots Association is the alliance of trade union forces of various airlines.
Therefore, in a sense, the International Federation of Airline Pilots Association is the largest civil aviation union in the world.
If Richard can intervene, at least the embarrassing situation that Lufthansa is facing now can be greatly alleviated.
In Europe and the United States, no enterprise dares to ignore the power of trade unions.It is precisely by mastering this power that causes headaches for all businessmen that Richard is truly unambiguous in the civil aviation industry.
"You have to protect the interests of Lufthansa, and I also want to protect the interests of the trade union." Richard said lightly: "However, one thing is right, you really shouldn't put aside other airlines to carry out salary increases on your own. In the absence of In the case of unification in advance, the unauthorized attack caused the current salary increase demonstration situation like an arms race, and the two of you should bear the main responsibility. I will not interfere with the activities of the trade unions of each division, but will only give guidance in the general direction, so , if you want me to take care of the current situation, then you seem to be thinking too much."
"You won't interfere with the activities of the trade unions of various divisions?" The president of Lufthansa Airways snorted coldly: "Now the unions of airlines that are slightly on the table in Europe are just around the corner. However, how do I hear that the union of British Kingfisher Airlines is quite Honestly?"
Although Kingfisher Airlines was once on the verge of bankruptcy, it has a place in the field of low-cost airlines in Europe.
But at a time when European airlines are all having headaches for salary increase demonstrations, Kingfisher Airlines in the United Kingdom has a peaceful appearance, and there is no trade union activity at all, as if the union of Kingfisher Airlines does not exist. of.
If you think that the Kingfisher Aviation Union's combat effectiveness is weak because of this, it is a big mistake.Before, Kingfisher Airlines delayed the payment of salaries due to financial constraints.
As a result, this move directly annoyed the trade union of Kingfisher Airlines. Not only did they go on strike, but they also protested in front of the British Ministry of Labor, which is really extremely tough.
However, it is obviously abnormal that such a highly active labor union has shown incomparable meekness in this wave of salary increases and will not cause trouble for the company at all.
The president of Lufthansa did not believe that Kingfisher's union was really so considerate.There is only one person who can stop the Kingfisher Aviation union, and that is Richard.
The president of KLM has a better relationship with Richard, and his words are not so oblique: "Richard, you are helping Kingfisher Airlines, why?"
"I heard that Kingfisher Airlines has a new owner recently." The chairman of Iberia Airlines added indifferently: "Before, when Kingfisher Airlines had financial problems, their union was not relentless. At that time, you can I didn’t see anyone helping Kingfisher Airlines. But now, you actually stopped the union of Kingfisher Airlines, and the only explanation is the new owner of Kingfisher Airlines.”
Richard raised his eyelids, but the cold light in his eyes was very cold: "This is a gift from me to someone. Why, do you want it too?"
The president of Lufthansa opened his mouth, but seeing Richard's displeased expression, he closed his mouth obediently.
However, the president of KLM, who has a good personal relationship with Richard, doesn't care much, and is quite curious: "Who is that person?"
Richard frowned, already a little bored.Suddenly, the door of the conference room was pushed open, and there was a lot of movement, which directly attracted the attention of most people in the conference room.
I saw that the person who came was the manager of the airport hotel. He was panting, his breathing was extremely rapid, and he seemed to be running over.
"What's wrong?" The host was not very happy. How could it be proper to be flustered on such an important occasion?
However, after taking a breath of relief, the manager of the airport hotel said in a somewhat mournful voice: "The airport has urgently reported, and I hope you all evacuate the hotel as soon as possible."
"Evacuate?" The president of KLM was puzzled: "What is the evacuation for? What happened?"
The manager of the airport hotel took another breath: "Just now, there was a report from the airport tower that a plane with a broken wing is about to land on runway 35. The extension line of runway 35 is just facing the hotel, so for safety's sake , it’s better to leave here.”
"The wing is broken!?" The president of KLM stood up suddenly: "You didn't say it earlier, let's go!"
However, he soon discovered that something was wrong, and almost no one followed him out.Instead, several people were looking out.
"What's the matter, don't you want to go?"
"If you're referring to hiding from that plane... that doesn't seem necessary." In the crowd, Richard also looked outside.
"Why?" The president of KLM was taken aback.
Richard looked far away, and there was a moving point in the sky not far away. It was nothing but the plane mentioned by the manager of the airport hotel.
The reason why Richard is so sure is that not long ago, Munich Airport stopped taking off and landing due to excessive wind volume. Under normal circumstances, there would be no planes approaching at all.
"A plane with a broken wing? Whoa!"
Some people want to go out to avoid some unexpected dangerous situations, but more people don't really care about it, and even become very interested.
Although this hotel is on the extension line of runway 35, it is still some distance away anyway.
Just because of this, you have to evacuate on purpose?It was really a fuss.
Among them, the reactions of many reporters were the most representative. They asked the photographers traveling with them to turn on the cameras, adjust the shooting angles, and point them to the sky on the fifth side of runway 35.
The broken wing of a large airliner is a piece of news at any time, and it is quite valuable to get the first-hand footage of the crash this time.
That's right, in the reporter's mind, the plane with the broken wing has been sentenced to death.
Richard pursed his lips, instead of sitting here quietly waiting to watch the "good show", he got up slowly and walked out of the conference room.
The president of KLM saw that Richard was leaving, so he hurriedly followed him: "Wait for me, where are you going?"
Richard had turned out of the conference room at this time, only to hear an indifferent voice from outside: "Airport."
At this moment, above the sky on the fifth edge of runway 35, British Airways Flight 531 is tilting its fuselage, aiming at the entrance of runway 35 at an oblique angle.
There is no way, no matter how Xu Cang restrains the huge right-rolling moment of the plane, this moment cannot be eliminated.Regarding this cognition, Xu Cang has quite enough realistic acceptance.
Therefore, under the premise that there is always a right roll moment, Xu Cang always keeps the aircraft on the left side of the fifth edge of the runway during approach.Fortunately, when the aircraft was initially guided to alternate landing, the initial heading of the aircraft was 010, and the trajectory of the aircraft happened to be cut from the left side of the fifth side.
In a sense, this relatively good initial position is more in line with Xu Cang's wishes, otherwise Xu Cang would need to work hard to adjust the position and approach direction.But now, due to various coincidences, Xu Cang only needs to fine-tune the trajectory of the plane so that the tangent point between the plane and the fifth side is just above the threshold of the runway.
Xu Cang's idea is very simple. For them and for the aircraft, this approach does not have an upright pentaplane.Due to the constant right roll moment, it is impossible for the aircraft to land normally along the extended line of the runway.
Therefore, the only option is to eliminate the final, cut directly over the runway from the left of the final, and then directly enter the touchdown attitude.
This means that before long, all the essence of the aircraft's movements will be in the brief time above the runway.The fate of a whole plane's people also depends on those few seconds of extreme operation.
For many people, this is not an excellent principle, because no matter from which point of view, such an operation is too risky.But for the current Xu Cang, it is the best choice to do his best in one battle. His current state is so peak that he feels that he can handle all flying problems well.
"Munich Airport, occupy the runway after landing, evacuate where you are, and ask for ground support." This is Xu Cang's last land-to-air call.
The control tower quickly responded: "British Airways 531, you can occupy the runway after landing, evacuate where you are, and airport support is in place. Good luck."
At this time, David was able to see runway 35 of Munich Airport relatively clearly.The speed of the plane was too high, and the approach rate to the runway was twice that of the normal landing configuration, which was almost dazzling, and the runway markings seemed to be a little clearer in the field of vision.
A thousand feet high!
"Xu Cang, do you need my cooperation for a while?" Under such circumstances, David no longer stopped Xu Cang, even now he thinks Xu Cang's final manipulation plan is too complicated.
That's right, just now Xu Cangguang explained the manipulation before landing, and David found it unbelievable, let alone realizing this manipulation with human brain power and muscle reaction ability.
Not only David, but Schneider sitting behind also felt that hope was extremely slim.He even thinks that even with the aid of the flight control computer, it will be difficult for human beings to complete Xu Cang's planned actions in the near future. Not to mention, the Boeing 777 does not have an advanced flight control computer like a high-performance fighter jet. Manipulate feedback.
"No, it will affect me if you join in the manipulation without authorization." Xu Cang took a deep breath: "Before landing, make an emergency landing notice. [-] feet, [-] feet, [-] feet and [-] feet!"
Although Xu Cang thinks that this is not the most important thing, if David wants to show his light and heat in the final stage, Xu Cang can only hand over these chores to him, and David can't do anything else.
At this moment, David was no longer picky. Looking at the approaching runway, he just said: "Xu Cang, I'm still a little nervous."
"Ignorance makes you nervous! If you are in my current state, you will find that the whole world has slowed down." Xu Cang adjusted his breathing, and at an altitude of two hundred feet, his eyes suddenly became fixed: "Start Already!"
"Two hundred feet high!"
In the sound of David's emergency landing broadcast, Xu Cang slowly held his breath, and slightly opened and closed his left hand.At this moment, he only felt that the blood in his whole body was boiling, and the suffocating feeling of welcoming the miracle made him feel extremely excited.
That's right, the plane hasn't landed yet, but Xu Cang has already simulated everything in his mind.
Everything is within his grasp.
"One hundred feet high!"
As David just put down the hand-held microphone for broadcasting, the plane was already very close to the sky above the runway.However, before reaching the sky above the runway, Xu Cang had already started to make moves.
The Boeing 777 is too big and has extremely strong inertia. You can't really wait until the plane flies over the runway before starting to make moves. It needs to be done a little earlier.
At this moment of life and death, Xu Cang directly stepped on the left rudder of the plane, then pushed the steering wheel forward a lot, and at the same time pressed it down sharply to the left.
At other times, such operations are very weird, especially the left full rudder and the left pressure plate are actually anti-control, that is to say, the combination of these two control actions is likely to cause some unexpected aircraft reactions Yes, for example, the plane rolls to the left.
However, at this time, Xu Cang's manipulation has completely transcended the situation that ordinary people recognize.
Under the full left rudder of the aircraft, under the premise of a large tilt angle, it is almost horizontal to the ground, and the vertical tail that acts as an elevator rises directly upwards, and the travel of the rudder surface is directly stretched to full.In a conventional aircraft, when the elevator goes up, the airflow will press down on the horizontal stabilizer, causing the tail to pitch down. Under the action of the torque, the nose will tilt up.
Then when the vertical tail, which is interchanged with the function of the elevator, rises up, it will bring the same effect, that is, the nose of the aircraft is raised, even if it is in a high-tilt attitude.
This is obviously not a normal maneuver that should be performed on the ground.
Because it's too early!Moreover, the action is too rough.
Just like the final leveling of a normal plane before landing, who would pitch the nose of the plane up to reduce the rate of descent when it is above [-] feet and before entering the sky above the runway?This kind of action to reduce sinking is too early to do at fifty feet, let alone above fifty feet.
Therefore, Xu Cang's idea is not to reduce the sinking of the plane and level the plane in disguise, but to have another effect.
At the same time, there were still some accelerator pedals that hadn't been turned on. At the moment when the left rudder was full, Xu Cang put all the accelerator pedals on the No. [-] engine.
At this moment, the eyelids of David sitting on the right seat twitched wildly.This operation was too familiar, and it was precisely because he knew Xu Cang's thoughts in advance that he felt that Xu Cang was simply playing with fire.
In analogy to a normal airplane, Xu Cang's control now is equivalent to suddenly blasting the accelerator all the way up during approach, and then slamming the steering wheel. This is an extremely standard error demonstration of excessive control, at least in conventional Pilots know.
This situation often occurs during go-arounds. Some inexperienced pilots immediately increase the throttle after deciding to go-around, and then instinctively pull the lever back, but it may be due to technical reasons or psychological factors. The amount of rod is too large.
At this time, instead of rising rapidly, the plane will lose speed with extremely exaggerated efficiency, and finally cause a stall.
Therefore, in the guidance of many experienced instructors, one thing must be mentioned more than once in the aspect of go-around control, that is, the initial go-around control must be soft.Under high thrust, you can't take the rod roughly, and sometimes you even have to push the rod slightly.
In some extreme cases, such as a zero-altitude go-around at an ultra-low altitude, this wrong maneuver will not only cause a stall, but most directly cause a tail strike.
There are too many precedents to show that a large part of the tail strike is due to the wrong control of zero altitude or ultra-low altitude go-around.
Who is David, the flight specialist of the ICAO European region, he has long been familiar with this kind of conventional flight control, and he can see through the problem of Xu Cang's full left rudder and full throttle at a glance.
But, would Xu Cang not know?
If a person who never makes a mistake makes a mistake, it is most likely not his mistake, but his intention.
Not long ago, Xu Cang said that he needed a differential horizontal tail, but the Boeing 777 does not have a differential tail, only a linked tail, so how to realize Xu Cang's idea?
With Xu Cang fully pulling the left rudder, and at the same time, the No. [-] engine throttle was applied to the maximum, and the nose of the plane was tilted up suddenly, which was very similar to the failure caused by the crew's control error during a go-around at ultra-low altitude. How big is the nose elevation angle?
When Xu Cang was operating the rudder and throttle, he also started to correct the landing direction of the plane, that is, the previous large ejector rod and left pressure plate, but he did not push the steering wheel all the way to the head, nor did he turn the steering wheel to the left Press it to the bottom, the reason for this is to maintain the tilt angle of the aircraft in a short period of time, so that the vertical tail can temporarily replace the role of the elevator.
If Xu Cang corrects the tilt angle too much, as the vertical tail is no longer in a roughly horizontal state, it will be impossible to complete the alternative pitching operation, at least Xu Cang does not want this to happen at this stage.
Because the secondary exchange of the rudder function of the vertical tail and the horizontal tail will involve extremely delicate and complicated control conversion, Xu Cang is going to move this conversion process to the final stage.
Moreover, he needs to keep the plane at a huge bank angle, but on the premise of maintaining the bank angle, don't let the plane deviate too far from the runway to the right.Therefore, Xu Cang will operate in advance to achieve the purpose of inputting advance amount.
With the exaggerated upward tilt of the nose of the plane, the tail of the plane is pushed down. At the same time, because Xu Cang did not correct the tilt angle of the plane by a large amount, this makes the horizontal tail on the right side enter the sky above the runway, because the altitude is too low. Suddenly hit the runway surface and broke apart on the spot.
"The tail was wiped?" Schneider's expression changed. The fuselage tremor caused by the right horizontal tail hitting the road surface just now was too obvious, and with such a huge elevation angle and such a low altitude, how could the plane not wipe the tail?
However, the more this happened, the more Schneider felt chills all over his body, because all this was within Xu Cang's expectation.
That's right, Xu Cang is deliberately causing the performance of wiping the tail of the plane.
The Boeing 777 does not have a differential horizontal stabilizer. To achieve this effect, the only way to achieve this effect is to destroy the horizontal stabilizer on one side, and Xu Cang chose the right horizontal stabilizer.
As long as there is a tail on one side and no tail on the other, isn't that equivalent to a differential tail in disguise?
It can only be said that when Xu Cang mentioned this idea not long ago, Schneider really wanted to say a madman, which is naked madness.
Wiping the tail of the aircraft is an absolutely dangerous action, but Xu Cang wants to use this dangerous action to complete the link he conceived, which is simply seeking skin from a tiger.However, Xu Cang's side is completely under control of this kind of dancing in Schneider's heart.
He has calculated everything, done everything, it is so easy and freehand!
This is the pinnacle of strength and skill!
Schneider could sense the tail rubbing, but Xu Cang, as the leader of everything, wouldn't he feel it?
He can maintain the bank angle of the aircraft so that when the tail is wiped, only the right horizontal tail is wiped off, not the rest of the tail.So, after achieving this effect, Xu Cang's eyes were fixed: "It's started!"
The operation of wiping the tail and breaking the horizontal tail that Schneider was terrified of was scary enough, but on Xu Cang's side, it was just an appetizer to achieve his goal.
What I have to admit is that breaking the wing and falling to the ground is indeed an impossible task for ordinary people, so Xu Cang has to do a lot of tricks.
After artificially completing the differential horizontal stabilizer, Xu Cang no longer hesitated, pushed the remaining steering wheel travel forward to full, and at the same time pressed the steering wheel to the left to death.This time, Xu Cang's movements were very rough, and there was indeed no room for delay.
Because, at the moment of rubbing the tail, the plane had already entered the air above the runway.Every extra second, the plane is consuming the final landing distance, so he must correct the plane to a conventional landing attitude as soon as possible, and at the same time reduce the speed to a suitable enough value.
Under the action of Xu Cang, after the previous aerial verification, under the joint action of the steering wheel ejector rod and the left pressure plate, the tilt angle of the aircraft was immediately restored by more than half, and reduced to less than [-] degrees.
But when in the air, why does this posture only last for a moment?
That's because as the bank angle decreases, the aircraft begins to return to its normal flight attitude, which means that the functions of the horizontal tail and vertical tail begin to normalize again, that is to say, the main function of the horizontal tail begins to return to control The aircraft pitches, and the main function of the vertical tail returns to the role of controlling the yaw of the aircraft.
Under such circumstances, the operation of the ejector rod of the aircraft cannot assist the aileron roll of the left pressure plate to suppress the right roll moment generated by the lift difference.Therefore, the aircraft will increase again after the bank angle decreases to a certain extent, until the normal functions of the horizontal stabilizer and vertical stabilizer are interchanged again.
However, if this is the case, it is just an invalid repetition of the previous operation, and the aircraft still cannot touch the ground in a normal attitude.
Because, Xu Cang had to restrain the aircraft from turning at the bank angle.
From fifty feet below, there is Xu Cang's splendid operation that is so brilliant that he can't look directly at it.
When the tilt angle of the aircraft decreases, the functions of the horizontal tail and the vertical tail begin to blur, so Xu Cang must change the input of the rudder surface with the decrease of the tilt angle.
As the wing of the plane gradually leveled off, Xu Cang kept the left pressure plate unchanged, but the movement of the ejector rod began to change, in a way that only relied on feeling, and began to transform into a backward rod.This is because the function of the action of pressing the plate to the left will not change due to the tilt angle of the aircraft, it is always generating a rolling moment to the left.However, the movement of the push rod or the rod is different.
After the wing gradually leveled off, the pitch control function of the vertical tail was slowly transferred back to the horizontal tail, and the previous action of pushing the rod forward to assist the ailerons was meaningless, so Xu Cang had to switch from the push rod to the belt. The lever is used to control the horizontal stabilizer that gradually restores the pitch function, so that the sinking of the aircraft is reduced.
This is a standard leveling process!
And Xu Cang's movement of resisting the left rudder did not stop, because after the large wing was leveled, the deflection moment formed by the thrust difference generated by the No. [-] engine on the horizontal plane began to become obvious.Therefore, Xu Cang must maintain the input of the left rudder to offset the rightward deflection moment, so that the aircraft remains on the center line of the runway.
However, this is not over yet!
In fact, even though Xu Cang is pressing the plate on the left, the leftward deflection moment generated by him resisting the left rudder has been almost offset by the natural rightward deflection moment caused by a single engine, which means that there is no deflection moment to assist the auxiliary The leftward roll moment of the wing.
Therefore, judging from previous manipulation experience, the leftward rolling moment of the left wing aileron alone cannot eliminate the rightward rolling moment caused by the lift difference, which means that the large wing changes Leveling is actually an illusion, just for a moment, the plane still has to bank to the right.
This is still a dead end!
However, Xu Cang wanted to find an impossible life in the dead situation.
Why does Xu Cang need a differential horizontal stabilizer?
After Xu Cang gradually converted the action of pushing the rod to the action of taking the rod, the elevator is actually tilted up.
If it is under the horizontal tail without damage, the elevators on both sides of the horizontal tail are raised at the same time, the airflow presses down on the horizontal tail, and the torque on both sides cancels out, so there will be no rolling moment to the left or right, but only Move down.
But it's different now, the horizontal tail on the right was broken due to Xu Cang's previous operation, and this made a difference.
From one side, the horizontal stabilizer is actually very similar to the large wing, so it can also generate rolling moment in essence.It's just that unlike the aileron used for rolling on the big wing, which moves in opposite directions, the elevator of the horizontal stabilizer moves in the same direction, so there will be no extra rolling moment, so Xu Cang wants to break this balance.
In the absence of the right horizontal tail, Xu Cang switched to the stick, and the elevator pitched up. In fact, it was very similar to the performance of Xu Cang's left pressure plate and the left wing aileron pitched up.
In this case, the left horizontal tail not only makes the nose up and reduces the sinking of the aircraft, but also generates an additional leftward rolling moment, which can be superimposed on the leftward rolling of the left aileron In the rotational moment, the rightward rolling moment generated by counteracting the difference in lift finally enables the aircraft to maintain a nearly level wing for a long time.
This is a standard landing attitude.
However, this is not enough!
Relying on the extra leftward rolling moment generated by the horizontal tail on one side of the aircraft is actually not enough to completely eliminate the rightward rolling moment caused by the lift difference. When the wing roll moment is reduced, the aircraft tilt angle will not be limited to [-] degrees for a short time.
Moreover, in any case, the wing area of the horizontal stabilizer on one side is still too small, which makes the additional rolling moment generated by it not very large.The plane will eventually roll to the right!
But, would Xu Cang allow this kind of thing to happen?
He starts with the stick, which creates an extra left-hand roll moment while reducing the sinking of the aircraft.
After about thirty feet, the sinking of the plane stabilized slightly, and then, that was enough!
Xu Cang never hoped to rely entirely on the aileron and one side of the horizontal tail to keep the wing level, it was too difficult.Moreover, the speed of the plane was too high, and it took a runway length to correct the plane's status before, so he had to do something.
what to doThen keep the wing level and reduce the speed of the aircraft together!
All I saw was that Xu Cang turned off all the throttle, and at the same time slightly reduced the input of the left rudder, and then directly pulled the speed brake to the flight stop.
These three actions are still done in one go!
Why do you want to close the throttle all at once?
Some people will feel that it is about to hit the ground, is it normal to close the throttle?
However, what is the effect of closing the throttle is not unique.
As soon as the throttle was turned off, Xu Cang still kept the movement of the stick, and the speed of the plane naturally dropped rapidly. Coupled with the speed brake, the deceleration efficiency was extremely exaggerated.
This first achieves the purpose of deceleration!
Second, as the thrust of the No. [-] engine is fully exhausted, the rightward yaw moment due to the thrust difference disappears.In this way, the leftward deflection moment generated by Xu Cang stepping on the left rudder can assist the rolling moment of the left aileron to better offset the rightward rolling moment.
However, Xu Cang can't fully step on the left rudder, otherwise the nose of the plane will deviate greatly to the left, resulting in a huge intersection angle when landing, which is extremely dangerous.
Use the right amount of continuous left rudder input to assist the aileron to complete the maintenance of the wing level, which is the second function brought by the Shuguang No. [-] engine.
Pulling up the speedbrake also has two purposes. The first is of course to slow down.
Only when the accelerator is slow and the speed brake is matched, can the best deceleration effect be achieved.The speed of the aircraft is too high, and only by using this deceleration method can the best effect be achieved.
In addition, with the lift of the speedbrake, the lift force on the surface of the wing is destroyed, which reduces the rightward roll moment caused by the difference in lift force.
Under the ebb and flow, the level of the big wing that was impossible to maintain was brought under control.
The reason why Xu Cang didn't pull up the speedbrake or close the throttle in advance was because he had to wait until the plane sank at a lower altitude and controlled it within a reasonable range.If you directly pull up the speedbrake and close the throttle without any explanation, you can indeed complete the wing level earlier, but if the plane falls down, the plane may be smashed and disintegrated on the spot.
Xu Cang gradually flattened the large wing from the beginning, and under the function of the horizontal tail and the vertical tail, the functions of the horizontal tail and the vertical tail were interchanged again.
When the sinking was under [-] feet, the speedbrakes and accelerator were moved only when the sinking was under control, while maintaining the movement with the stick, in order to decelerate faster and control the sinking.
However, in any case, pulling the speedbrake before touching the ground is an extremely risky action.No matter how conservative Xu Cang was, at the last height of less than ten meters, the wheels of the plane smashed hard on the runway.
"Oh!"
The moment he touched the ground, Xu Cang heard a loud noise, and his expression changed suddenly. It was clearly the sound of a flat tire.
Under the huge impact force, some tires were directly crushed.
What's more, what Xu Cang couldn't see was that the support columns of the two main landing gears were directly compressed in the innermost part.
"Manual brakes, step on it!" David roared, and before Xu Cang got on his feet, he stepped on the automatic brakes and trampled all the brakes on both sides to death.
Under the action of the landing gear, the speed of the aircraft had dropped to the minimum when it touched down. After David stepped on the brakes, the friction between the wheels and the road surface caused a cloud of smoke.
However, it seems that the puncture is only a small number and does not affect the braking effect of the aircraft.
Xu Cang didn't step on the brakes anymore, it didn't make any sense. According to the deceleration effect, he could be sure that the plane could stop.
It can only be said that the deceleration effect of the Boeing 777 wheel car is extremely amazing, but in the state of being trampled to death, the plane still barely stops in front of the runway. Looking at the lights, the remaining distance is less than 300 meters.
"Survived?" David released the brake, set the parking brake, and looked around.
He tried his best to control himself, but the excitement of remaining alive after the catastrophe could no longer be suppressed.
Compared to David's ecstasy, Schneider just let out a long breath.
He looked at Xu Cang who didn't have much expression on his face, and said softly: "Xu Cang, make the last [-] feet of manipulation data public, the world should know what a miracle is!"
It's crazy, it's just crazy!
To be honest, the operation of the last [-] feet is interlocking, one step cannot be wrong, and the involvement is extremely complicated, it is really an extremely exquisitely designed handicraft.
In the last [-] feet, Schneider lost the ability to think at all, and couldn't appreciate Xu Cang's extremely complicated operation and design.However, after the plane stopped, he felt more and more chills down his spine.
Really someone can be stronger than the ability of the flight control computer!
If it really exists, it is a complete miracle!
Everyone should admire it!
At this moment, David's emotions gradually calmed down, but the way he looked at Xu Cang was completely different. It was really like looking at a god, and even the broken wing could land safely, which was completely beyond human imagination.
"Xu Cang, is there anything you can't do?" David asked that extremely sincere question with infinite admiration.
"Now. No!" Xu Cang took a deep breath. His whole body was steaming with heat, and the beating of his heart was like drumming and thunder, and his blood was boiling like a flame.
His state has not passed away, he has a second game!
He slowly turned his head and looked at the terrifying air mass that was as oppressive as an ancient sacred mountain under the dusk.
It seems that the light that shines on it is swallowed up, so that it looks like ink from the outside.It is a monster that can devour everything, and it seems that the Alps have entered its belly.
Oppression, the most primitive oppression, no one can be presumptuous in front of it!
At this time, David noticed Xu Cang's gaze: "What are you looking at?"
The corner of Xu Cang's mouth curled up, and he slowly raised his head, pointing to the cyclone clouds covering the sky and the earth in the distance, covering the entire Alps: "I want to go there!"
(End of this chapter)
In a large conference room on the top floor of a high-end hotel near Munich Airport, senior executives of several major European airlines gathered together, discussing the increasingly prosperous European civil aviation industry driven by the issuance of the euro.
Among them are the presidents or chairman of internationally renowned airlines such as Air France, Lufthansa, KLM, and Alitalia.
In this small conference room, except for the representative of British Airways who did not come, almost [-]% of the European civil aviation forces were included.However, in addition to this, the focus of the meeting was a non-airline person, that is Richard, the president of the International Federation of Airline Pilots Association.
No one can ignore Richard's existence, but in the daily operation of the company, the International Federation of Airline Pilots Association does not interfere.Therefore, Richard has become indispensable, but rarely speaks in the meeting.
The level of this meeting is relatively high. After all, it brought together almost the entire civil aviation power in Europe. There must be many media reporters rushing to report on this level of business meeting. The cameras in the circle behind the participants and the Journalists are the best proof.
In any case, the content of the conversation in the meeting is to be made public.This kind of content that needs to be made public is cautious in words and deeds and lacks substantive content.The top executives of several companies just read the prepared and polished manuscripts in advance.
During the meeting, there were no quarrels, no verbal confrontation, and some just passed the air ahead of time, just like acting for a show.In this default state, everyone maintains their dignity as business elites.
The formal meeting lasted about an hour. After the host proposed a break at halftime, these elites who were sitting upright and meticulous immediately showed a relaxed posture, and some even chatted with the reporters around them, chatting Talk about the effects that might appear in the newspapers tomorrow.
The media personnel who can be invited are naturally screened, knowing what can be filmed and what cannot be filmed.During the halftime session, all the surrounding cameras were turned off sensibly, and a group of bigwigs from the airlines began to enjoy this rare time for chatting.
As the actual controller of the European civil aviation industry, this circle is very small, so these people basically know each other.Among them, the president of Royal Dutch Airlines saw Richard who was not interested, and asked with a smile: "Richard, I heard that Isiris is trapped in the Alps. Is there such a thing?"
It can be seen that the KLM president has a good personal relationship with Richard.Richard is called by a shortened nickname.
If the original plan had been followed, the vacation plan of British Airways President Isiris would have ended yesterday.Then, of course, I came to Munich by private helicopter, rested for one night, and attended the conference the next day without any delay.
Munich is close to the northern foothills of the Alps. Even a slower helicopter will not take too long, which is convenient.
However, as the Alps encountered a rare blizzard, representatives of British Airways were absent from the European Civil Aviation Conference.
Richard also works part-time as a technical consultant for British Airways, ask him is the best choice.
"You look very happy. Although I don't know why you are so happy, but if Isiris comes back and knows your reaction to this, the cooperation project between you and British Airways may be very dangerous." Reason Chad laughed.
"Richard, you're just so bored, spending some time at British Airways, don't you really think of yourself as a British Airways person?" The president of Royal Dutch Airlines smiled brightly: "And, if you really care about British Airways Airline. Then British Airways’ recent strikes wouldn’t be so drastic, would they?”
Compared with the slightly frivolous demeanor of the president of KLM, the president of Lufthansa is much more stable, just like the image of this old airline.
"Richard, with the launch of the euro, the European civil aviation market is overheated. We admit that airlines can grow considerably in it. However, we also hope that the unions will not have too much appetite. This is not for both parties. Good thing."
As soon as the president of Lufthansa Air Lines finished speaking, the chairman of Alitalia began to joke: "Didn't Lufthansa raise your salary a while ago? Why, the union is not satisfied now and wants to raise the salary again." ?”
The president of Lufthansa Airways kept silent and did not answer this question at all.
The chairman of Spain's national airline just sneered: "It deserves it!"
As soon as this remark came out, the president of Lufthansa immediately changed his face and slapped the table: "What did you say?"
"What did I say? I said that Lufthansa deserves what you deserve." The chairman of Iberia directly confronted: "You Lufthansa and Air France clearly know that European airlines will affect each other. In the end, they rushed up without telling us. The salary is 12.00%, which directly puts us in an embarrassing situation. That is, British Airways’ Isiris did not come, otherwise he is the one who scolds you now. As far as I know, the average salary increase of the British Airways union [-]%. Not long ago, our trade union asked us to ask for a [-]% salary increase. These are all good things you have done."
For things like salary increases, whoever takes the initiative to do so will take the initiative, and can raise salary at a smaller rate.However, this has caused other airlines to suffer.
The labor unions of the remaining airlines will directly refer to the previous wage increase standards when they follow up the strike, and then the chances are that the labor unions of the remaining airlines will increase their demands for salary increases. In terms of the performance of the union, it almost perfectly confirmed the idea of the chairman of the Spanish national airline.
Among them, the British Airways labor union has the greatest appetite, directly increasing the average salary increase by [-]%, which has brought a huge financial burden to British Airways.
These aviation bosses all know that in the current extremely hot market, salary increases are imperative.However, how to suppress the salary increase as much as possible when the labor market is dominant is what these big bosses need to consider.
In fact, the best way is for the leaders of major European airlines to reach an agreement on the salary increase in advance, and not to change it easily.
As long as all the companies are united and have a unified caliber, it will be easier to dismiss the trade union.
However, Lufthansa and Air France sold all the remaining airlines in order to seize the opportunity.
However, as the initiators of active salary increases, Lufthansa and Air France actually only received short-term benefits.
After betting on the mouths of their own unions with an average salary increase of [-]%, in recent days, the union representatives of Lufthansa and Air France, after learning that the wage increases of other companies' unions are generally more than [-]%, directly tore up The memorandum reached with the company also raised the salary increase by [-]%.
This makes the leadership of Lufthansa and Air France a buffoon.
In order to save some financial expenses for salary increases, it was at the cost of ruining his own reputation.In the end, the reputation is bad, but nothing has changed. What do the leadership of Lufthansa and Air France think?
The most important force in Richard's International Federation of Airline Pilots Association is the alliance of trade union forces of various airlines.
Therefore, in a sense, the International Federation of Airline Pilots Association is the largest civil aviation union in the world.
If Richard can intervene, at least the embarrassing situation that Lufthansa is facing now can be greatly alleviated.
In Europe and the United States, no enterprise dares to ignore the power of trade unions.It is precisely by mastering this power that causes headaches for all businessmen that Richard is truly unambiguous in the civil aviation industry.
"You have to protect the interests of Lufthansa, and I also want to protect the interests of the trade union." Richard said lightly: "However, one thing is right, you really shouldn't put aside other airlines to carry out salary increases on your own. In the absence of In the case of unification in advance, the unauthorized attack caused the current salary increase demonstration situation like an arms race, and the two of you should bear the main responsibility. I will not interfere with the activities of the trade unions of each division, but will only give guidance in the general direction, so , if you want me to take care of the current situation, then you seem to be thinking too much."
"You won't interfere with the activities of the trade unions of various divisions?" The president of Lufthansa Airways snorted coldly: "Now the unions of airlines that are slightly on the table in Europe are just around the corner. However, how do I hear that the union of British Kingfisher Airlines is quite Honestly?"
Although Kingfisher Airlines was once on the verge of bankruptcy, it has a place in the field of low-cost airlines in Europe.
But at a time when European airlines are all having headaches for salary increase demonstrations, Kingfisher Airlines in the United Kingdom has a peaceful appearance, and there is no trade union activity at all, as if the union of Kingfisher Airlines does not exist. of.
If you think that the Kingfisher Aviation Union's combat effectiveness is weak because of this, it is a big mistake.Before, Kingfisher Airlines delayed the payment of salaries due to financial constraints.
As a result, this move directly annoyed the trade union of Kingfisher Airlines. Not only did they go on strike, but they also protested in front of the British Ministry of Labor, which is really extremely tough.
However, it is obviously abnormal that such a highly active labor union has shown incomparable meekness in this wave of salary increases and will not cause trouble for the company at all.
The president of Lufthansa did not believe that Kingfisher's union was really so considerate.There is only one person who can stop the Kingfisher Aviation union, and that is Richard.
The president of KLM has a better relationship with Richard, and his words are not so oblique: "Richard, you are helping Kingfisher Airlines, why?"
"I heard that Kingfisher Airlines has a new owner recently." The chairman of Iberia Airlines added indifferently: "Before, when Kingfisher Airlines had financial problems, their union was not relentless. At that time, you can I didn’t see anyone helping Kingfisher Airlines. But now, you actually stopped the union of Kingfisher Airlines, and the only explanation is the new owner of Kingfisher Airlines.”
Richard raised his eyelids, but the cold light in his eyes was very cold: "This is a gift from me to someone. Why, do you want it too?"
The president of Lufthansa opened his mouth, but seeing Richard's displeased expression, he closed his mouth obediently.
However, the president of KLM, who has a good personal relationship with Richard, doesn't care much, and is quite curious: "Who is that person?"
Richard frowned, already a little bored.Suddenly, the door of the conference room was pushed open, and there was a lot of movement, which directly attracted the attention of most people in the conference room.
I saw that the person who came was the manager of the airport hotel. He was panting, his breathing was extremely rapid, and he seemed to be running over.
"What's wrong?" The host was not very happy. How could it be proper to be flustered on such an important occasion?
However, after taking a breath of relief, the manager of the airport hotel said in a somewhat mournful voice: "The airport has urgently reported, and I hope you all evacuate the hotel as soon as possible."
"Evacuate?" The president of KLM was puzzled: "What is the evacuation for? What happened?"
The manager of the airport hotel took another breath: "Just now, there was a report from the airport tower that a plane with a broken wing is about to land on runway 35. The extension line of runway 35 is just facing the hotel, so for safety's sake , it’s better to leave here.”
"The wing is broken!?" The president of KLM stood up suddenly: "You didn't say it earlier, let's go!"
However, he soon discovered that something was wrong, and almost no one followed him out.Instead, several people were looking out.
"What's the matter, don't you want to go?"
"If you're referring to hiding from that plane... that doesn't seem necessary." In the crowd, Richard also looked outside.
"Why?" The president of KLM was taken aback.
Richard looked far away, and there was a moving point in the sky not far away. It was nothing but the plane mentioned by the manager of the airport hotel.
The reason why Richard is so sure is that not long ago, Munich Airport stopped taking off and landing due to excessive wind volume. Under normal circumstances, there would be no planes approaching at all.
"A plane with a broken wing? Whoa!"
Some people want to go out to avoid some unexpected dangerous situations, but more people don't really care about it, and even become very interested.
Although this hotel is on the extension line of runway 35, it is still some distance away anyway.
Just because of this, you have to evacuate on purpose?It was really a fuss.
Among them, the reactions of many reporters were the most representative. They asked the photographers traveling with them to turn on the cameras, adjust the shooting angles, and point them to the sky on the fifth side of runway 35.
The broken wing of a large airliner is a piece of news at any time, and it is quite valuable to get the first-hand footage of the crash this time.
That's right, in the reporter's mind, the plane with the broken wing has been sentenced to death.
Richard pursed his lips, instead of sitting here quietly waiting to watch the "good show", he got up slowly and walked out of the conference room.
The president of KLM saw that Richard was leaving, so he hurriedly followed him: "Wait for me, where are you going?"
Richard had turned out of the conference room at this time, only to hear an indifferent voice from outside: "Airport."
At this moment, above the sky on the fifth edge of runway 35, British Airways Flight 531 is tilting its fuselage, aiming at the entrance of runway 35 at an oblique angle.
There is no way, no matter how Xu Cang restrains the huge right-rolling moment of the plane, this moment cannot be eliminated.Regarding this cognition, Xu Cang has quite enough realistic acceptance.
Therefore, under the premise that there is always a right roll moment, Xu Cang always keeps the aircraft on the left side of the fifth edge of the runway during approach.Fortunately, when the aircraft was initially guided to alternate landing, the initial heading of the aircraft was 010, and the trajectory of the aircraft happened to be cut from the left side of the fifth side.
In a sense, this relatively good initial position is more in line with Xu Cang's wishes, otherwise Xu Cang would need to work hard to adjust the position and approach direction.But now, due to various coincidences, Xu Cang only needs to fine-tune the trajectory of the plane so that the tangent point between the plane and the fifth side is just above the threshold of the runway.
Xu Cang's idea is very simple. For them and for the aircraft, this approach does not have an upright pentaplane.Due to the constant right roll moment, it is impossible for the aircraft to land normally along the extended line of the runway.
Therefore, the only option is to eliminate the final, cut directly over the runway from the left of the final, and then directly enter the touchdown attitude.
This means that before long, all the essence of the aircraft's movements will be in the brief time above the runway.The fate of a whole plane's people also depends on those few seconds of extreme operation.
For many people, this is not an excellent principle, because no matter from which point of view, such an operation is too risky.But for the current Xu Cang, it is the best choice to do his best in one battle. His current state is so peak that he feels that he can handle all flying problems well.
"Munich Airport, occupy the runway after landing, evacuate where you are, and ask for ground support." This is Xu Cang's last land-to-air call.
The control tower quickly responded: "British Airways 531, you can occupy the runway after landing, evacuate where you are, and airport support is in place. Good luck."
At this time, David was able to see runway 35 of Munich Airport relatively clearly.The speed of the plane was too high, and the approach rate to the runway was twice that of the normal landing configuration, which was almost dazzling, and the runway markings seemed to be a little clearer in the field of vision.
A thousand feet high!
"Xu Cang, do you need my cooperation for a while?" Under such circumstances, David no longer stopped Xu Cang, even now he thinks Xu Cang's final manipulation plan is too complicated.
That's right, just now Xu Cangguang explained the manipulation before landing, and David found it unbelievable, let alone realizing this manipulation with human brain power and muscle reaction ability.
Not only David, but Schneider sitting behind also felt that hope was extremely slim.He even thinks that even with the aid of the flight control computer, it will be difficult for human beings to complete Xu Cang's planned actions in the near future. Not to mention, the Boeing 777 does not have an advanced flight control computer like a high-performance fighter jet. Manipulate feedback.
"No, it will affect me if you join in the manipulation without authorization." Xu Cang took a deep breath: "Before landing, make an emergency landing notice. [-] feet, [-] feet, [-] feet and [-] feet!"
Although Xu Cang thinks that this is not the most important thing, if David wants to show his light and heat in the final stage, Xu Cang can only hand over these chores to him, and David can't do anything else.
At this moment, David was no longer picky. Looking at the approaching runway, he just said: "Xu Cang, I'm still a little nervous."
"Ignorance makes you nervous! If you are in my current state, you will find that the whole world has slowed down." Xu Cang adjusted his breathing, and at an altitude of two hundred feet, his eyes suddenly became fixed: "Start Already!"
"Two hundred feet high!"
In the sound of David's emergency landing broadcast, Xu Cang slowly held his breath, and slightly opened and closed his left hand.At this moment, he only felt that the blood in his whole body was boiling, and the suffocating feeling of welcoming the miracle made him feel extremely excited.
That's right, the plane hasn't landed yet, but Xu Cang has already simulated everything in his mind.
Everything is within his grasp.
"One hundred feet high!"
As David just put down the hand-held microphone for broadcasting, the plane was already very close to the sky above the runway.However, before reaching the sky above the runway, Xu Cang had already started to make moves.
The Boeing 777 is too big and has extremely strong inertia. You can't really wait until the plane flies over the runway before starting to make moves. It needs to be done a little earlier.
At this moment of life and death, Xu Cang directly stepped on the left rudder of the plane, then pushed the steering wheel forward a lot, and at the same time pressed it down sharply to the left.
At other times, such operations are very weird, especially the left full rudder and the left pressure plate are actually anti-control, that is to say, the combination of these two control actions is likely to cause some unexpected aircraft reactions Yes, for example, the plane rolls to the left.
However, at this time, Xu Cang's manipulation has completely transcended the situation that ordinary people recognize.
Under the full left rudder of the aircraft, under the premise of a large tilt angle, it is almost horizontal to the ground, and the vertical tail that acts as an elevator rises directly upwards, and the travel of the rudder surface is directly stretched to full.In a conventional aircraft, when the elevator goes up, the airflow will press down on the horizontal stabilizer, causing the tail to pitch down. Under the action of the torque, the nose will tilt up.
Then when the vertical tail, which is interchanged with the function of the elevator, rises up, it will bring the same effect, that is, the nose of the aircraft is raised, even if it is in a high-tilt attitude.
This is obviously not a normal maneuver that should be performed on the ground.
Because it's too early!Moreover, the action is too rough.
Just like the final leveling of a normal plane before landing, who would pitch the nose of the plane up to reduce the rate of descent when it is above [-] feet and before entering the sky above the runway?This kind of action to reduce sinking is too early to do at fifty feet, let alone above fifty feet.
Therefore, Xu Cang's idea is not to reduce the sinking of the plane and level the plane in disguise, but to have another effect.
At the same time, there were still some accelerator pedals that hadn't been turned on. At the moment when the left rudder was full, Xu Cang put all the accelerator pedals on the No. [-] engine.
At this moment, the eyelids of David sitting on the right seat twitched wildly.This operation was too familiar, and it was precisely because he knew Xu Cang's thoughts in advance that he felt that Xu Cang was simply playing with fire.
In analogy to a normal airplane, Xu Cang's control now is equivalent to suddenly blasting the accelerator all the way up during approach, and then slamming the steering wheel. This is an extremely standard error demonstration of excessive control, at least in conventional Pilots know.
This situation often occurs during go-arounds. Some inexperienced pilots immediately increase the throttle after deciding to go-around, and then instinctively pull the lever back, but it may be due to technical reasons or psychological factors. The amount of rod is too large.
At this time, instead of rising rapidly, the plane will lose speed with extremely exaggerated efficiency, and finally cause a stall.
Therefore, in the guidance of many experienced instructors, one thing must be mentioned more than once in the aspect of go-around control, that is, the initial go-around control must be soft.Under high thrust, you can't take the rod roughly, and sometimes you even have to push the rod slightly.
In some extreme cases, such as a zero-altitude go-around at an ultra-low altitude, this wrong maneuver will not only cause a stall, but most directly cause a tail strike.
There are too many precedents to show that a large part of the tail strike is due to the wrong control of zero altitude or ultra-low altitude go-around.
Who is David, the flight specialist of the ICAO European region, he has long been familiar with this kind of conventional flight control, and he can see through the problem of Xu Cang's full left rudder and full throttle at a glance.
But, would Xu Cang not know?
If a person who never makes a mistake makes a mistake, it is most likely not his mistake, but his intention.
Not long ago, Xu Cang said that he needed a differential horizontal tail, but the Boeing 777 does not have a differential tail, only a linked tail, so how to realize Xu Cang's idea?
With Xu Cang fully pulling the left rudder, and at the same time, the No. [-] engine throttle was applied to the maximum, and the nose of the plane was tilted up suddenly, which was very similar to the failure caused by the crew's control error during a go-around at ultra-low altitude. How big is the nose elevation angle?
When Xu Cang was operating the rudder and throttle, he also started to correct the landing direction of the plane, that is, the previous large ejector rod and left pressure plate, but he did not push the steering wheel all the way to the head, nor did he turn the steering wheel to the left Press it to the bottom, the reason for this is to maintain the tilt angle of the aircraft in a short period of time, so that the vertical tail can temporarily replace the role of the elevator.
If Xu Cang corrects the tilt angle too much, as the vertical tail is no longer in a roughly horizontal state, it will be impossible to complete the alternative pitching operation, at least Xu Cang does not want this to happen at this stage.
Because the secondary exchange of the rudder function of the vertical tail and the horizontal tail will involve extremely delicate and complicated control conversion, Xu Cang is going to move this conversion process to the final stage.
Moreover, he needs to keep the plane at a huge bank angle, but on the premise of maintaining the bank angle, don't let the plane deviate too far from the runway to the right.Therefore, Xu Cang will operate in advance to achieve the purpose of inputting advance amount.
With the exaggerated upward tilt of the nose of the plane, the tail of the plane is pushed down. At the same time, because Xu Cang did not correct the tilt angle of the plane by a large amount, this makes the horizontal tail on the right side enter the sky above the runway, because the altitude is too low. Suddenly hit the runway surface and broke apart on the spot.
"The tail was wiped?" Schneider's expression changed. The fuselage tremor caused by the right horizontal tail hitting the road surface just now was too obvious, and with such a huge elevation angle and such a low altitude, how could the plane not wipe the tail?
However, the more this happened, the more Schneider felt chills all over his body, because all this was within Xu Cang's expectation.
That's right, Xu Cang is deliberately causing the performance of wiping the tail of the plane.
The Boeing 777 does not have a differential horizontal stabilizer. To achieve this effect, the only way to achieve this effect is to destroy the horizontal stabilizer on one side, and Xu Cang chose the right horizontal stabilizer.
As long as there is a tail on one side and no tail on the other, isn't that equivalent to a differential tail in disguise?
It can only be said that when Xu Cang mentioned this idea not long ago, Schneider really wanted to say a madman, which is naked madness.
Wiping the tail of the aircraft is an absolutely dangerous action, but Xu Cang wants to use this dangerous action to complete the link he conceived, which is simply seeking skin from a tiger.However, Xu Cang's side is completely under control of this kind of dancing in Schneider's heart.
He has calculated everything, done everything, it is so easy and freehand!
This is the pinnacle of strength and skill!
Schneider could sense the tail rubbing, but Xu Cang, as the leader of everything, wouldn't he feel it?
He can maintain the bank angle of the aircraft so that when the tail is wiped, only the right horizontal tail is wiped off, not the rest of the tail.So, after achieving this effect, Xu Cang's eyes were fixed: "It's started!"
The operation of wiping the tail and breaking the horizontal tail that Schneider was terrified of was scary enough, but on Xu Cang's side, it was just an appetizer to achieve his goal.
What I have to admit is that breaking the wing and falling to the ground is indeed an impossible task for ordinary people, so Xu Cang has to do a lot of tricks.
After artificially completing the differential horizontal stabilizer, Xu Cang no longer hesitated, pushed the remaining steering wheel travel forward to full, and at the same time pressed the steering wheel to the left to death.This time, Xu Cang's movements were very rough, and there was indeed no room for delay.
Because, at the moment of rubbing the tail, the plane had already entered the air above the runway.Every extra second, the plane is consuming the final landing distance, so he must correct the plane to a conventional landing attitude as soon as possible, and at the same time reduce the speed to a suitable enough value.
Under the action of Xu Cang, after the previous aerial verification, under the joint action of the steering wheel ejector rod and the left pressure plate, the tilt angle of the aircraft was immediately restored by more than half, and reduced to less than [-] degrees.
But when in the air, why does this posture only last for a moment?
That's because as the bank angle decreases, the aircraft begins to return to its normal flight attitude, which means that the functions of the horizontal tail and vertical tail begin to normalize again, that is to say, the main function of the horizontal tail begins to return to control The aircraft pitches, and the main function of the vertical tail returns to the role of controlling the yaw of the aircraft.
Under such circumstances, the operation of the ejector rod of the aircraft cannot assist the aileron roll of the left pressure plate to suppress the right roll moment generated by the lift difference.Therefore, the aircraft will increase again after the bank angle decreases to a certain extent, until the normal functions of the horizontal stabilizer and vertical stabilizer are interchanged again.
However, if this is the case, it is just an invalid repetition of the previous operation, and the aircraft still cannot touch the ground in a normal attitude.
Because, Xu Cang had to restrain the aircraft from turning at the bank angle.
From fifty feet below, there is Xu Cang's splendid operation that is so brilliant that he can't look directly at it.
When the tilt angle of the aircraft decreases, the functions of the horizontal tail and the vertical tail begin to blur, so Xu Cang must change the input of the rudder surface with the decrease of the tilt angle.
As the wing of the plane gradually leveled off, Xu Cang kept the left pressure plate unchanged, but the movement of the ejector rod began to change, in a way that only relied on feeling, and began to transform into a backward rod.This is because the function of the action of pressing the plate to the left will not change due to the tilt angle of the aircraft, it is always generating a rolling moment to the left.However, the movement of the push rod or the rod is different.
After the wing gradually leveled off, the pitch control function of the vertical tail was slowly transferred back to the horizontal tail, and the previous action of pushing the rod forward to assist the ailerons was meaningless, so Xu Cang had to switch from the push rod to the belt. The lever is used to control the horizontal stabilizer that gradually restores the pitch function, so that the sinking of the aircraft is reduced.
This is a standard leveling process!
And Xu Cang's movement of resisting the left rudder did not stop, because after the large wing was leveled, the deflection moment formed by the thrust difference generated by the No. [-] engine on the horizontal plane began to become obvious.Therefore, Xu Cang must maintain the input of the left rudder to offset the rightward deflection moment, so that the aircraft remains on the center line of the runway.
However, this is not over yet!
In fact, even though Xu Cang is pressing the plate on the left, the leftward deflection moment generated by him resisting the left rudder has been almost offset by the natural rightward deflection moment caused by a single engine, which means that there is no deflection moment to assist the auxiliary The leftward roll moment of the wing.
Therefore, judging from previous manipulation experience, the leftward rolling moment of the left wing aileron alone cannot eliminate the rightward rolling moment caused by the lift difference, which means that the large wing changes Leveling is actually an illusion, just for a moment, the plane still has to bank to the right.
This is still a dead end!
However, Xu Cang wanted to find an impossible life in the dead situation.
Why does Xu Cang need a differential horizontal stabilizer?
After Xu Cang gradually converted the action of pushing the rod to the action of taking the rod, the elevator is actually tilted up.
If it is under the horizontal tail without damage, the elevators on both sides of the horizontal tail are raised at the same time, the airflow presses down on the horizontal tail, and the torque on both sides cancels out, so there will be no rolling moment to the left or right, but only Move down.
But it's different now, the horizontal tail on the right was broken due to Xu Cang's previous operation, and this made a difference.
From one side, the horizontal stabilizer is actually very similar to the large wing, so it can also generate rolling moment in essence.It's just that unlike the aileron used for rolling on the big wing, which moves in opposite directions, the elevator of the horizontal stabilizer moves in the same direction, so there will be no extra rolling moment, so Xu Cang wants to break this balance.
In the absence of the right horizontal tail, Xu Cang switched to the stick, and the elevator pitched up. In fact, it was very similar to the performance of Xu Cang's left pressure plate and the left wing aileron pitched up.
In this case, the left horizontal tail not only makes the nose up and reduces the sinking of the aircraft, but also generates an additional leftward rolling moment, which can be superimposed on the leftward rolling of the left aileron In the rotational moment, the rightward rolling moment generated by counteracting the difference in lift finally enables the aircraft to maintain a nearly level wing for a long time.
This is a standard landing attitude.
However, this is not enough!
Relying on the extra leftward rolling moment generated by the horizontal tail on one side of the aircraft is actually not enough to completely eliminate the rightward rolling moment caused by the lift difference. When the wing roll moment is reduced, the aircraft tilt angle will not be limited to [-] degrees for a short time.
Moreover, in any case, the wing area of the horizontal stabilizer on one side is still too small, which makes the additional rolling moment generated by it not very large.The plane will eventually roll to the right!
But, would Xu Cang allow this kind of thing to happen?
He starts with the stick, which creates an extra left-hand roll moment while reducing the sinking of the aircraft.
After about thirty feet, the sinking of the plane stabilized slightly, and then, that was enough!
Xu Cang never hoped to rely entirely on the aileron and one side of the horizontal tail to keep the wing level, it was too difficult.Moreover, the speed of the plane was too high, and it took a runway length to correct the plane's status before, so he had to do something.
what to doThen keep the wing level and reduce the speed of the aircraft together!
All I saw was that Xu Cang turned off all the throttle, and at the same time slightly reduced the input of the left rudder, and then directly pulled the speed brake to the flight stop.
These three actions are still done in one go!
Why do you want to close the throttle all at once?
Some people will feel that it is about to hit the ground, is it normal to close the throttle?
However, what is the effect of closing the throttle is not unique.
As soon as the throttle was turned off, Xu Cang still kept the movement of the stick, and the speed of the plane naturally dropped rapidly. Coupled with the speed brake, the deceleration efficiency was extremely exaggerated.
This first achieves the purpose of deceleration!
Second, as the thrust of the No. [-] engine is fully exhausted, the rightward yaw moment due to the thrust difference disappears.In this way, the leftward deflection moment generated by Xu Cang stepping on the left rudder can assist the rolling moment of the left aileron to better offset the rightward rolling moment.
However, Xu Cang can't fully step on the left rudder, otherwise the nose of the plane will deviate greatly to the left, resulting in a huge intersection angle when landing, which is extremely dangerous.
Use the right amount of continuous left rudder input to assist the aileron to complete the maintenance of the wing level, which is the second function brought by the Shuguang No. [-] engine.
Pulling up the speedbrake also has two purposes. The first is of course to slow down.
Only when the accelerator is slow and the speed brake is matched, can the best deceleration effect be achieved.The speed of the aircraft is too high, and only by using this deceleration method can the best effect be achieved.
In addition, with the lift of the speedbrake, the lift force on the surface of the wing is destroyed, which reduces the rightward roll moment caused by the difference in lift force.
Under the ebb and flow, the level of the big wing that was impossible to maintain was brought under control.
The reason why Xu Cang didn't pull up the speedbrake or close the throttle in advance was because he had to wait until the plane sank at a lower altitude and controlled it within a reasonable range.If you directly pull up the speedbrake and close the throttle without any explanation, you can indeed complete the wing level earlier, but if the plane falls down, the plane may be smashed and disintegrated on the spot.
Xu Cang gradually flattened the large wing from the beginning, and under the function of the horizontal tail and the vertical tail, the functions of the horizontal tail and the vertical tail were interchanged again.
When the sinking was under [-] feet, the speedbrakes and accelerator were moved only when the sinking was under control, while maintaining the movement with the stick, in order to decelerate faster and control the sinking.
However, in any case, pulling the speedbrake before touching the ground is an extremely risky action.No matter how conservative Xu Cang was, at the last height of less than ten meters, the wheels of the plane smashed hard on the runway.
"Oh!"
The moment he touched the ground, Xu Cang heard a loud noise, and his expression changed suddenly. It was clearly the sound of a flat tire.
Under the huge impact force, some tires were directly crushed.
What's more, what Xu Cang couldn't see was that the support columns of the two main landing gears were directly compressed in the innermost part.
"Manual brakes, step on it!" David roared, and before Xu Cang got on his feet, he stepped on the automatic brakes and trampled all the brakes on both sides to death.
Under the action of the landing gear, the speed of the aircraft had dropped to the minimum when it touched down. After David stepped on the brakes, the friction between the wheels and the road surface caused a cloud of smoke.
However, it seems that the puncture is only a small number and does not affect the braking effect of the aircraft.
Xu Cang didn't step on the brakes anymore, it didn't make any sense. According to the deceleration effect, he could be sure that the plane could stop.
It can only be said that the deceleration effect of the Boeing 777 wheel car is extremely amazing, but in the state of being trampled to death, the plane still barely stops in front of the runway. Looking at the lights, the remaining distance is less than 300 meters.
"Survived?" David released the brake, set the parking brake, and looked around.
He tried his best to control himself, but the excitement of remaining alive after the catastrophe could no longer be suppressed.
Compared to David's ecstasy, Schneider just let out a long breath.
He looked at Xu Cang who didn't have much expression on his face, and said softly: "Xu Cang, make the last [-] feet of manipulation data public, the world should know what a miracle is!"
It's crazy, it's just crazy!
To be honest, the operation of the last [-] feet is interlocking, one step cannot be wrong, and the involvement is extremely complicated, it is really an extremely exquisitely designed handicraft.
In the last [-] feet, Schneider lost the ability to think at all, and couldn't appreciate Xu Cang's extremely complicated operation and design.However, after the plane stopped, he felt more and more chills down his spine.
Really someone can be stronger than the ability of the flight control computer!
If it really exists, it is a complete miracle!
Everyone should admire it!
At this moment, David's emotions gradually calmed down, but the way he looked at Xu Cang was completely different. It was really like looking at a god, and even the broken wing could land safely, which was completely beyond human imagination.
"Xu Cang, is there anything you can't do?" David asked that extremely sincere question with infinite admiration.
"Now. No!" Xu Cang took a deep breath. His whole body was steaming with heat, and the beating of his heart was like drumming and thunder, and his blood was boiling like a flame.
His state has not passed away, he has a second game!
He slowly turned his head and looked at the terrifying air mass that was as oppressive as an ancient sacred mountain under the dusk.
It seems that the light that shines on it is swallowed up, so that it looks like ink from the outside.It is a monster that can devour everything, and it seems that the Alps have entered its belly.
Oppression, the most primitive oppression, no one can be presumptuous in front of it!
At this time, David noticed Xu Cang's gaze: "What are you looking at?"
The corner of Xu Cang's mouth curled up, and he slowly raised his head, pointing to the cyclone clouds covering the sky and the earth in the distance, covering the entire Alps: "I want to go there!"
