Chapter 234 Cang-style maneuver!I am indeed the strongest! (Please subscribe!)
In the cockpit of the plane, Xu Cang's words were still echoing in Chen Guoli's mind. He really couldn't understand why Xu Cang had the idea of being able to complete the verification.
In fact, as long as there is a possibility that he recognizes, Chen Guoli will be willing to take risks for it, even if it means giving his life.
But can Xu Cang really see the road ahead?
Just when Chen Guoli was confused, Xu Cang said softly: "Believe in me, it's like believing in a miracle itself."
Xu Cang seemed to be talking to Chen Guoli, but it seemed that he was not, but was talking to himself.In his eyes, the two figures on the right side of the mountain platform are as small as gravel, and it seems that the two people are also carrying camera equipment, which is what Bilin hopes to record Xu Cang's path to life Prepare.
It's a pity that now Bi Lin has lost hope, and only Xu Cang persists.
Chen Guoli looked at the side face of Xu Cang who was as firm as a rock, as if he had been infected, he suddenly became proud: "Okay, I prepared for the worst. You, a young man in his 20s, are not afraid. I have almost lived my life, so what are you afraid of. Tell me, what do you want me to do?"
"After I turn around, the program on the navigation page will disappear. I need you to recall the program and make quick approach preparations."
If the program on the navigation page on the 737 passes a certain point, the navigation point will disappear.If the plane were to turn back, the previous programmed route would have disappeared, and it would be quite dangerous if the plane did not fly according to the programmed route.
Therefore, after Xu Cang made a U-turn, Chen Guoli needed to manually retrieve the procedure a second time.This is not a complicated job, but Xu Cang's follow-up operations will require a lot of effort. If Chen Guoli is willing, it is naturally better to leave it to Chen Guoli.
Now that there is a two-person system, then give full play to the effectiveness of the two-person system.At least Xu Cang can concentrate on the operation.
"Approach preparation? Which runway to land on, 28? 10?"
In fact, even Chen Guoli couldn't understand Xu Cang's thoughts.Xu Cang's thinking is too transcendent, he may be talking about the first step, but in fact he has already thought about the second, third, fourth and fifth steps, and Chen Guoli can't keep up with Xu Cang's thinking development speed, So I can only ask the co-pilot about everything.
Xu Cang did not tire of his troubles, and this is not a big deal: "Runway 28."
Although the plane should land on runway 10 if it returns according to the original procedure, Xu Cang said that it would still use runway 28. Chen Guoli was puzzled by the difference.But Chen Guoli, who had made up his mind, did not intend to ask any more questions, saving Xu Cang's mind.
Suddenly, Chen Guoli found that the airspeed didn't drop any more, and he was pleasantly surprised: "The speed doesn't drop anymore, and the downdraft has decreased."
Previously, due to the strong downdraft, the aircraft had been using speed loss in exchange for maintaining altitude, but now the speed cannot be lost, which means that the downdraft is not as strong as before.
Does that mean that they still have a little possibility of overcoming obstacles?Or did Xu Cang expect the downdraft to decrease?However, this kind of thing can be expected, it is too amazing, it is completely beyond common sense.
However, Xu Cang could see clearly.Chen Guoli's mental arithmetic ability is not good, not to mention that the downdraft is only reduced now, the plane still can't recover to climb.
Even if the downdraft completely disappears at this moment, and the ascent rate of the plane returns to the previous level, it will be quite difficult to cross the last hill.
As Bi Lin said, they had lost their last chance to climb over the last obstacle.Moreover, Xu Cang never thought of climbing over this mountain.
"That's because the air flow is dispersed by the mountain pass ahead."
Further on, the plane is quite close to the mountain pass on the right.The closer to the mountain pass, the southwest wind is under the topographic pressure of the windward slope, unlike other areas, the airflow can only be forced to lift, but when it crosses the top of the mountain, it forms a downdraft torrent.
Near the mountain pass, part of the airflow moves horizontally and vents from the mountain pass. Therefore, the closer to the mountain pass, the smaller the energy of the downdraft jet.
When the plane enters the area where the horizontal airflow hits the mountain pass, there will be horizontal airflow there, without any vertical airflow.
Theoretically speaking, the normal ascent operation can be completed in the horizontal airflow area vented from the mountain pass.However, the mountain pass was too close to the last obstacle, and it was not enough to resume climbing to complete the obstacle.
In the end, even Chen Guoli was aware of the problem: "Xu Cang, we must not be able to climb over?"
Suddenly, as the plane was about to cut through the mountain pass, the downdraft that suppressed the plane finally almost disappeared.Not only did the speed no longer drop, but the plane began to rise slowly.
However, in the end, the mountain was close at hand, and even if the ascent resumed, the plane was unable to climb over it.At this moment, it can be seen from the terrain display of TCAS that if you want to cross the mountain, you need to rise more than [-] feet.
The immovable mountain peaks blocked the plane like a gate of heaven, the distance was so close, and the mountain peaks in front were as steep as a knife and an axe.
The sacred mountain was in front of him, solemn and solemn, which made Chen Guoli feel fearful.
"Xu Cang, what should we do, we can't make it through!"
Even though he was mentally prepared, Chen Guoli still couldn't stop his heart beating wildly when he really smelled the breath of death, and couldn't suppress it at all.
"I said, then I won't climb! Get ready, listen to my password!"
In an instant, the muscles of Xu Cang's whole body tensed up, and that moment was finally coming.
It's time to show the real technology!
At the moment when Xu Cang's voice fell, Xu Cang slammed the pole and turned slightly to the left at the same time, the slope was extremely small and did not exceed ten degrees.
Under this operation, Chen Guoli was shocked. It is understandable for him to take the pole, but what is the purpose of turning left?Moreover, Xu Cang's turning slope is very small, which will undoubtedly greatly increase the turning radius. Isn't this a dead end?
Both Wang Li and Bi Lin have said before that because the distance between the two sides of the canyon is too close, the plane has to hit the hillside as soon as it turns.But instead of increasing the slope and reducing the radius, Xu Cang turns with a small slope. Isn't that the opposite?
However, Xu Cang's move brought about a very serious consequence.That is, in the case of a single engine, the power of the aircraft is insufficient, Xu Cang forced the lever, and the rate of ascent was increased, but the power provided by the engine was not enough to maintain the rate of ascent, and the speed that had just stabilized began to drop again.
However, the speed was maintained above 230 knots before, so a slight drop in altitude is actually okay.Therefore, during the time of losing speed, Chen Guoli can be regarded as calm.
However, he soon discovered a problem.Because Xu Cang took the stick too hard, the plane suddenly formed an ascent rate of nearly [-] feet per minute, and in a short time, the plane rose more than [-] feet.
However, judging from the terrain display, the mountain to be crossed before is still in red, so it seems that its highest point is still more than [-] feet higher than the plane.Apparently, Chen Guoli's estimate of the climb height is still missing.
Previously, Chen Guoli felt that the plane would be able to climb over the mountain if it climbed more than 2000 feet.But now it seems that it may be more than three thousand feet,
There is no way, the time of ascent was wasted in the previous period, and even fell a little. The pressure of the ascent is all concentrated up to now, which is indeed too much pressure.
However, if you can maintain an ascent rate of more than [-] feet, you may still have a try.However, this height increase is at the cost of losing the speed of the aircraft. It is very likely that the aircraft will fall into a deep stall just after reaching the top of the mountain, and that is still a dead end.
Moreover, the most important thing is that Xu Cang didn't fly forward at all, but turned around.
wrong!As the nose of the plane turned slowly, Chen Guoli suddenly discovered that the plane was facing the gap in the mountain range.Could it be that Xu Cang is going to fly towards that mountain pass?But didn't Wang Li just say that after the mountain pass is the main line of Tianshan Mountain, once he enters it, he will die beyond death.
"Xu Cang, you can't go there, there are mountains behind!" Chen Guoli shouted loudly.
Could it be that Xu Cang was in a daze, he thought Xu Cang had some kind of clever plan, but he didn't expect to go into the main vein area of Tianshan Mountain!What kind of trick is this?
However, before Xu Cang could reply, Chen Guoli looked down and found that the airspeed of the plane was already lower than the UP speed.However, Xu Cang's hands kept moving, and he was still holding the stick backwards, so that the speed dropped continuously, and he was about to enter the yellow warning zone.
Chen Guoli's face changed drastically: "Xu Cang, don't take it anymore, you're going to shake the stick!"
What exactly is going on?Flying towards the mountain pass, recklessly taking the pole, this is Xu Cang's method, what is he going to do?
But at the moment when Chen Guoli's words stopped, Xu Cang suddenly leveled the plane, and the direction of its nose was obliquely facing the mountain pass.
The expression on Chen Guoli's face froze for an instant, and his heart almost stopped.
"Are you really going to fly to the mountain pass?"
However, the moment Chen Guoli had the idea, Xu Cang suddenly shouted: "EEC is hard to spare!"
Chen Guoli was taken aback. To be honest, he didn't understand 1 things, 1 things he didn't understand.With nearly 30 years of flying experience, he couldn't even touch the traces of Xu Cang's thinking.
Earlier, Chen Guoli was still questioning whether Xu Cang had lost his mind.But now, what Xu Cang said seems to indicate that everything is far from that simple.
"Okay!" Chen Guoli is a bit nice, he doesn't understand what Xu Cang is going to do, he will question and be puzzled, but when Xu Cang gives the order clearly, Chen Guoli will still do it without hesitation!
Sure enough, after hesitating in the blink of an eye, Chen Guoli no longer had any doubts, but directly took off his seat belt, got up and pressed the EEC control switch on the rear roof.
EEC switch, that is, full-efficiency digital engine control switch.This switch is only available in the NG series, the previous 737-300 and 737-500 models are not this switch, but the PMC switch in the same position.
The shape and appearance of these two switches are very similar, but their functions are not the same.
The EEC switch is a very typical two-channel switch, which is similar to auto boost, speed trim, Mach trim, etc.Any one of these channels can theoretically undertake independent work.Under normal circumstances, the two channels are switched to each other, and the switching node is every time the engine starts or tries to start.
In normal mode, the EEC calculates an N1 value based on the position of the thrust lever, temperature, pressure and bleed air load.However, sometimes there is a deviation between the actual N1 and the calculated N1. At this time, the EEC will adjust the fuel flow to make the two consistent.
At the same time, EEC can also provide functions such as idle control, flameout protection and ground start protection.
However, in some cases, the working channel of the EEC fails. The EEC will automatically switch to the soft standby state, and the ALTN and ON lights will be on at this time.
At this moment, EEC will use the last effective flight status to define the power parameters, so as to ensure that the engine power will not change when the mode is changed.
However, if the thrust levers are retracted to idle, or a new standby mode is manually selected, the soft standby mode will cease to function.
The standby mode can be changed to hard standby by pressing the EEC switch, and the ALTN light is off at this moment.In hard standby mode, the EEC is referenced to thrust lever position and internal data.
When manually selecting the hard standby mode, the thrust handle needs to be placed in the middle position first, because in the hard standby mode, its thrust is always greater than or equal to the thrust in the normal mode.
However, when Xu Cang asked Chen Guoli to manually select the EEC hard standby mode, the position of the thrust handle was at the front.Based on the thrust logic in hard standby mode, when the thrust handle is placed at the front, the relevant engine will obtain the limit N1 exceeding the maximum thrust in normal mode!
Just when Chen Guoli pressed the EEC switch, the No. [-] engine was like a wild horse running wild.
It's just that in that moment, the N1 value has rushed to an unprecedented 105%!
You should know that the limit of N1 is between 102% and 105%. As long as it exceeds 105%, it will easily cause the engine to exceed the limit.In other words, at this moment, the No. [-] engine has reached the edge of overrun.
However, with such a surge of thrust, the aircraft's rate of ascent directly exceeded [-] feet per minute.
When Chen Guoli chose hard backup, he didn't pay attention to the position of the thrust handle at all.After pressing the EEC switch this time, he lowered his head and noticed that Xu Cang had pushed the thrust handle of the No. [-] engine to the front.
All of a sudden, Chen Guoli's scalp was numb: "Xu Cang, the second serve is about to exceed the limit!"
"in spite of!"
While Xu Cang was speaking, he continued to raise his head, and finally the speed dropped below the UP speed, and he had already entered the yellow warning zone.The moment the speed indicator entered the yellow warning zone, the pitch limit indicator appeared on the PFD central attitude indicator.
Chen Guoli's face turned pale, and he shouted: "The speed is in the yellow zone!"
"I don't care what I said!" Xu Cang roared: "The spare flap release switch is in the preset position, and the spare flap position switch is tapped once, and the leading edge device is fully deployed!"
Chen Guoli's mind is really blank at the moment, the spare flaps are basically used when the trailing edge flaps are inconsistent, but they are still in a clean state, so why use the spare flaps.
However, there is a function of the spare flap extension, which is to extend the leading edge unit alone without touching the trailing edge flap.Because the leading edge device is linked with the trailing edge flap, only this method can release the leading edge device independently.
If the standby flap position switch is pressed continuously for a long time, the trailing edge flap will also be released, so it can only be tapped lightly.
"Do whatever you want!"
Chen Guoli also roared. At this moment, his mind was muddled, but he still obeyed the previous promise, he would do whatever Xu Cang said.
The spare flap switch is on the upper left of the front roof. Fortunately, Chen Guoli has not fastened his seat belt yet, so he gets up and opens the red cover of the spare flap switch, then pre-positions the switch, and finally taps Depress the right alternate flap position switch.
"All right!"
Just as Chen Guoli spoke, suddenly there was a shaking of the stick in his ears.In an instant, the hairs of Chen Guoli's whole body exploded, and he looked down at the airspeed indicator, and sure enough, the speed had entered the red and black speed zone, and Xu Cang's right hand holding the steering wheel was also shaking continuously with the shaking of the stick.
However, what made Chen Guoli feel unbelievable was that Xu Cang was still holding the stick, so that the speed of the plane continued to decrease.
"You are crazy, you are still holding the stick after stalling!"
Pushing the stick to reduce the aircraft's angle of attack during a stall is almost in the pilot's DNA.But now that the plane is shaking its stick, Xu Cang is still using the stick to increase the angle of attack. Isn't this adding fuel to the fire?
When it comes to instinctive things, Chen Guoli subconsciously wants to intervene and manipulate.However, Xu Cang shouted in a low voice: "The stick is shaken, but is it stalled?"
This short sentence struck Chen Guoli's heart like a thunderbolt.
That's right, the speed of the plane is almost [-] knots below the red and black speed bands, and the plane's ground speed is less than [-] knots, but Xu Cang is still pulling the stick backwards, and Chen Guoli is almost lying flat He stared straight at the gray sky.
"How did this happen, how did this happen, why hasn't the nose of the plane dropped yet?" Chen Guoli almost screamed, and such phenomena had already surpassed his cognition.
Aircraft stick shake is not equal to a real stall, Chen Guoli is fully aware of this.Due to the stall margin, the stick shaker speed is approximately 1.3 times the stall speed.
That is to say, if the aircraft will really stall when the speed is lower than 130 knots, but in fact, the stick shake warning will appear after the aircraft speed is lower than [-] knots.
The interval of [-] knots is the safety margin given to the crew.
But now this speed is too low, the true airspeed is barely better, and the ground speed has been reduced by less than [-] knots. Even so, the nose of the plane has not yet dropped.
Once the aircraft enters a deep stall, the airflow on the surface of the wing will completely separate from the wing, so the lift force disappears, and the aircraft just bows its head and falls straight down like an iron bump.But now, the plane doesn't seem to have lost its lift.
what is this?Why hasn't the airflow separated yet, and why does lift still exist?
However, Xu Cang didn't explain it to Chen Guoli at all, and when Chen Guoli was thinking wildly, the nose of the plane, which was raised beyond the limit, started to rotate to the left at a huge elevation angle, and the whole plane was a bit like a pendulum.
In fact, the plane does not really hover in the air, at least no large-scale civil aviation company can do the hovering operation.It's just that the aircraft's speed is extremely low at this moment, so that its turning radius is very small, which is a bit similar to turning without radius.
Chen Guoli on the left noticed that the rudder under his feet was slightly stepped on the left rudder the moment he realized that the nose of the plane was turning.Naturally, this was not his action, but Xu Cang's stepping on it.
However, to be precise, it is not stepping on, but releasing the right rudder.Because the No. [-] engine stalled, Xu Cang naturally had to keep the input of the right rudder to eliminate the sideslip caused by the unbalanced thrust.
Therefore, as long as Xu Cang releases the right rudder slightly, the plane will turn left naturally.
Chen Guoli can understand the operation of turning the nose of the aircraft.What he didn't understand was why the nose of the plane hadn't dropped, and why the airflow hadn't separated.
However, in any case, it doesn't matter whether Chen Guoli can understand it or not.Since the speed of the aircraft has dropped to an unbelievable level, the turning radius of the aircraft has been reduced to an equally unimaginable level.
In just a moment, the nose of the plane turned over more than 90 degrees.When the nose of the plane passed the mountain pass, Chen Guoli looked at the gap in the mountain range that looked like a gate of heaven, and a flash of inspiration suddenly flashed in his mind, and he seemed to understand.
"It's the wind, the strong wind!"
The essence of a stall is that the airflow is separated from the wing surface due to the excessive angle of attack, which is a basic flight principle.Only certain fighter jets can achieve post-stall maneuvers due to vector thrust and special starting layout, but large civil aviation airliners absolutely cannot, at least it is absolutely impossible to form such an exaggerated elevation angle and such a terrible low speed to maintain maneuver control.
However, Xu Cang did it!
What he can do is to use the violent horizontal airflow from the mountain pass.
Thinking about it now, Xu Cang was turning left with a slight slope to level off, and the nose of the aircraft was roughly facing the mountain pass not to pass through the mountain pass, but to adjust the angle to obtain a relatively larger headwind air volume.
The essence of a stall is the angle of attack, but from the perspective of ordinary people, it is always felt that the root of the stall is the low speed.This is of course a one-sided concept, but the truth behind it is not entirely wrong.
Because when the aircraft is at a low speed, the speed of the airflow passing on the surface of the wing will also decrease, making it easier to separate from the wing performance, so that the lift force is reduced.
However, if the airflow itself has a huge velocity.Even if the speed of the aircraft is small, the relative speed is very high. Even at high angles of attack, the high-speed airflow can still press the airflow to fit the wing surface as much as possible.
The horizontal airflow with violent energy vented by the mountain pass is the source of the best high-speed airflow.Moreover, since the altitude of the aircraft is not very high at this moment, the air is not as thin as that at high altitudes, which can still give the aircraft a huge increase in aerodynamic performance.
If the same situation occurs at high altitude, the effect will be greatly reduced.
However, this is not enough!
Therefore, Xu Cang needs to switch the No. [-] engine to hard standby mode in order to obtain more extreme thrust.At the same time, the leading edge device is deployed to delay the flow separation.
Xu Cang is very clear-headed, he only needs the leading edge device, but not the trailing edge flap.Although flaps can increase lift, they will significantly increase the camber of the wing, making it easier to separate the airflow.
In other words, extending the trailing edge flaps will increase the stall speed, so it is necessary to avoid extending the trailing edge flaps.
Whether it is to use the airflow of the mountain pass, or to increase the thrust limit, or to expand the leading edge device, everything is to delay the separation of the airflow.
It was these preparations that made Xu Cang complete such a masterpiece!
For some reason, Chen Guoli remembered that he had gone to flight school abroad to fly a Cessna 152 several times.If you encounter a strong headwind in the air and do Power On Stall at the same time, just like Xu Cang at this moment, the plane maintains an extremely exaggerated elevation angle, but the plane does not speed.
Perhaps, the two are somewhat related.
But what is a Cessna 152 and what is a 737?Xu Cang was able to complete such a miraculous operation on this tens of tons behemoth, which simply broke through human cognition.
At this moment, Ji Dong and Wang Wen, who were filming on the top of the mountain, were the closest to the plane.At the beginning, Wang Wen was still focused on shooting, but when the plane rotated in an incredible way, he felt that his world view was about to collapse.
He is from the design institute, so he naturally knows some flying knowledge.But it is precisely because of the knowledge of flying that I feel how terrifying the scene in front of me is. Is this really the maneuver that an aircraft like 737 can fly out of?
"Brother, am I right?" Wang Wen almost shouted, "What the hell is going on?"
Ji Dong's mouth was slightly open, his mind was blank, everything in front of him had refreshed his cognition over and over again.Taking a deep breath, Ji Dong forcibly suppressed the throbbing in his heart, and picked up the walkie-talkie: "Tower, tower, can you see the plane? It's in the sky near the scheduled observation position."
In the tower control room, when everyone was still shocked by the fact that Xu Cang's plane signal was almost hovering, Ji Dong's voice came in.
Wang Li reacted first, ran to the corner of the control room, pulled out a telescope, and looked in the direction of the canyon.
Bi Lin was also very excited at this moment, and immediately walked to Wang Li's side: "Did you find it?"
It stands to reason that the plane cannot be seen from the tower side.However, because Xu Cang lifted the plane, Wang Li located the plane in the gap between the mountain peaks.
But when he saw the maneuvering state of the plane, his whole body was shocked, as if he had seen the most terrifying thing, and even the hand holding the binoculars was shaking.
"What's the matter?" Bi Lin saw Wang Li's appearance and knew that something must have happened, but Wang Li didn't say a word, and Bi Lin was so angry that he knocked on his crutch a few times.
Wang Li put down the binoculars slowly, his mouth was still half open, and it seemed that he still hadn't recovered.
Zhou Yanping also ran over and said anxiously, "Stationmaster Wang, what's the matter?"
Wang Li took a deep breath, his lips were trembling, his eyes were still a little dull, and after a while, he slowly turned to Bi Lin: "Old Bi, he...he turned around, as if he was hovering in the air."
"What did you say!?" Bi Lin turned pale with shock, "Impossible, how could 737 hover in the air, it's impossible!"
Zhou Yanping didn't speak, but he also felt that Wang Li was wrong, because it is absolutely impossible for the 737 to hover in the air, and it is not the kind of fighter jet that takes off and lands vertically.
"Stationmaster Wang"
What else did Zhou Yanping want to say.Suddenly, the tower controller said: "Station Master, the signal of 1533 has started to return."
As soon as this statement came out, everyone gathered in front of the radar screen, regardless of whether they were actually hovering in the air or not.Sure enough, at this moment, the signal point of the plane is slightly back than before.
All of a sudden, Zhou Yanping felt confused: "Is this really turning back?"
In the cockpit, Xu Cang was adjusting the input of the rudder. After the nose started to rotate, he no longer took the stick, but kept the pitch attitude unchanged.
With Chen Guoli on the side, he was already automatically unable to hold himself back, and Chen Guoli only felt honored to be able to experience such a miraculous operation in person.
As the nose is gradually turned back, the headwind volume begins to decrease.Xu Cang then began to reduce the attitude of the plane to prevent the plane from really entering a deep stall.
However, Xu Cang did not reduce the pitch attitude quickly, otherwise the plane would deviate too much from the programmed route due to turning, and problems would easily occur.However, when there was still about thirty degrees to turn, Xu Cang suddenly felt a little strange shaking of the steering wheel.In an instant, Xu Cang's face changed suddenly, it was really about to stall.
Fortunately, there were only [-] degrees left in the end. Xu Cang pushed down the steering wheel, and the nose of the plane immediately followed, and the lift rate suddenly decreased to a negative number.
"Call the program again!" Xu Cang was able to distract Chen Guoli while reducing the angle of attack.
Chen Guoli woke up instantly, without hesitation, he immediately operated on the CDU, and re-tuned the single-shot program.As the single-shot program appeared on the navigation page, Xu Cang immediately had a level reference.
Xu Cang's action of pushing the pole was rather inquisitive, and he did so while maintaining a high thrust.This is actually not very good, because too much thrust makes it easier for the plane to look up, and it is not easy to push the nose down.
However, in order to recover as soon as possible, Xu Cang naturally ignored these things.At the same time as the ejector rod, the main electric trim wheel rattles forward at the same time.
Recovering from the stall requires a loss of altitude. If it is at the programmed altitude, such a dive will cause serious accidents.However, Xu Cang raised the plane by almost [-] feet in the process of leading the stick.This height is just for Xu Cang to recover from the stall.
However, the stall Xu Cang encountered was already relatively deep, and two thousand feet was already relatively tense.Knowing this reason, Xu Cang had to use full thrust to recover from the stall, so as to control the lost height to the maximum.
It has to be said that Xu Cang's way of getting out of the stall is really like dancing with the tip of a knife.The attitude of the aircraft is right next to the pitch limit indicator, which is really not bad at all.
In this way, the altitude lost by the aircraft can be minimized.
In the end, Xu Cang re-adjusted the thrust and speed, and at the same time pushed the heading onto the programmed route, and the altitude was firmly fixed at the height limited by the program.
Looking at the direction of the turned nose, even for Xu Cang, it was full of pride.
It is this kind of turning the impossible into the possible that is the most exciting, and Xu Cang is this kind of person who turns things around.
Chen Guoli was also flushed with excitement, he didn't expect to survive, and Xu Cang found a chance of survival in the inevitable situation.
After turning on the horizontal navigation and automatic driving, Xu Cang couldn't control the surging pride in his heart anymore.Since Yulong Airport, he has never experienced this kind of feeling again, that kind of joyful feeling of grasping and controlling fate.
The sky has the intention of being unstoppable, but there is absolutely no way for Xu Cang to reverse the sky!
Xu Cang let go of the steering wheel with his right hand, and looked far away, looking at the outside world.At this moment, he only felt that the sky seemed to be a little shorter. At this moment, his ecstatic and fearless roar resounded through the entire sky: "I am indeed the strongest!"
Xu Cang's long whistle fell in Chen Guoli's ears, and he also felt his heart pounding.Living in this world, to reach Xu Cang's step, I really have no regrets.
Moreover, Xu Cang's move pointed out a way of survival for the latecomers in the desperate situation.
He really did it!
However, when the two fell into boundless joy, the EGT value of the No. [-] engine suddenly began to vibrate slightly, but none of this was seen by the two of them!
I don’t think it will be until evening tomorrow, and I may have to ask for leave, depending on the situation. I’ve been busy with work recently, and the update time is messy.
(End of this chapter)
In the cockpit of the plane, Xu Cang's words were still echoing in Chen Guoli's mind. He really couldn't understand why Xu Cang had the idea of being able to complete the verification.
In fact, as long as there is a possibility that he recognizes, Chen Guoli will be willing to take risks for it, even if it means giving his life.
But can Xu Cang really see the road ahead?
Just when Chen Guoli was confused, Xu Cang said softly: "Believe in me, it's like believing in a miracle itself."
Xu Cang seemed to be talking to Chen Guoli, but it seemed that he was not, but was talking to himself.In his eyes, the two figures on the right side of the mountain platform are as small as gravel, and it seems that the two people are also carrying camera equipment, which is what Bilin hopes to record Xu Cang's path to life Prepare.
It's a pity that now Bi Lin has lost hope, and only Xu Cang persists.
Chen Guoli looked at the side face of Xu Cang who was as firm as a rock, as if he had been infected, he suddenly became proud: "Okay, I prepared for the worst. You, a young man in his 20s, are not afraid. I have almost lived my life, so what are you afraid of. Tell me, what do you want me to do?"
"After I turn around, the program on the navigation page will disappear. I need you to recall the program and make quick approach preparations."
If the program on the navigation page on the 737 passes a certain point, the navigation point will disappear.If the plane were to turn back, the previous programmed route would have disappeared, and it would be quite dangerous if the plane did not fly according to the programmed route.
Therefore, after Xu Cang made a U-turn, Chen Guoli needed to manually retrieve the procedure a second time.This is not a complicated job, but Xu Cang's follow-up operations will require a lot of effort. If Chen Guoli is willing, it is naturally better to leave it to Chen Guoli.
Now that there is a two-person system, then give full play to the effectiveness of the two-person system.At least Xu Cang can concentrate on the operation.
"Approach preparation? Which runway to land on, 28? 10?"
In fact, even Chen Guoli couldn't understand Xu Cang's thoughts.Xu Cang's thinking is too transcendent, he may be talking about the first step, but in fact he has already thought about the second, third, fourth and fifth steps, and Chen Guoli can't keep up with Xu Cang's thinking development speed, So I can only ask the co-pilot about everything.
Xu Cang did not tire of his troubles, and this is not a big deal: "Runway 28."
Although the plane should land on runway 10 if it returns according to the original procedure, Xu Cang said that it would still use runway 28. Chen Guoli was puzzled by the difference.But Chen Guoli, who had made up his mind, did not intend to ask any more questions, saving Xu Cang's mind.
Suddenly, Chen Guoli found that the airspeed didn't drop any more, and he was pleasantly surprised: "The speed doesn't drop anymore, and the downdraft has decreased."
Previously, due to the strong downdraft, the aircraft had been using speed loss in exchange for maintaining altitude, but now the speed cannot be lost, which means that the downdraft is not as strong as before.
Does that mean that they still have a little possibility of overcoming obstacles?Or did Xu Cang expect the downdraft to decrease?However, this kind of thing can be expected, it is too amazing, it is completely beyond common sense.
However, Xu Cang could see clearly.Chen Guoli's mental arithmetic ability is not good, not to mention that the downdraft is only reduced now, the plane still can't recover to climb.
Even if the downdraft completely disappears at this moment, and the ascent rate of the plane returns to the previous level, it will be quite difficult to cross the last hill.
As Bi Lin said, they had lost their last chance to climb over the last obstacle.Moreover, Xu Cang never thought of climbing over this mountain.
"That's because the air flow is dispersed by the mountain pass ahead."
Further on, the plane is quite close to the mountain pass on the right.The closer to the mountain pass, the southwest wind is under the topographic pressure of the windward slope, unlike other areas, the airflow can only be forced to lift, but when it crosses the top of the mountain, it forms a downdraft torrent.
Near the mountain pass, part of the airflow moves horizontally and vents from the mountain pass. Therefore, the closer to the mountain pass, the smaller the energy of the downdraft jet.
When the plane enters the area where the horizontal airflow hits the mountain pass, there will be horizontal airflow there, without any vertical airflow.
Theoretically speaking, the normal ascent operation can be completed in the horizontal airflow area vented from the mountain pass.However, the mountain pass was too close to the last obstacle, and it was not enough to resume climbing to complete the obstacle.
In the end, even Chen Guoli was aware of the problem: "Xu Cang, we must not be able to climb over?"
Suddenly, as the plane was about to cut through the mountain pass, the downdraft that suppressed the plane finally almost disappeared.Not only did the speed no longer drop, but the plane began to rise slowly.
However, in the end, the mountain was close at hand, and even if the ascent resumed, the plane was unable to climb over it.At this moment, it can be seen from the terrain display of TCAS that if you want to cross the mountain, you need to rise more than [-] feet.
The immovable mountain peaks blocked the plane like a gate of heaven, the distance was so close, and the mountain peaks in front were as steep as a knife and an axe.
The sacred mountain was in front of him, solemn and solemn, which made Chen Guoli feel fearful.
"Xu Cang, what should we do, we can't make it through!"
Even though he was mentally prepared, Chen Guoli still couldn't stop his heart beating wildly when he really smelled the breath of death, and couldn't suppress it at all.
"I said, then I won't climb! Get ready, listen to my password!"
In an instant, the muscles of Xu Cang's whole body tensed up, and that moment was finally coming.
It's time to show the real technology!
At the moment when Xu Cang's voice fell, Xu Cang slammed the pole and turned slightly to the left at the same time, the slope was extremely small and did not exceed ten degrees.
Under this operation, Chen Guoli was shocked. It is understandable for him to take the pole, but what is the purpose of turning left?Moreover, Xu Cang's turning slope is very small, which will undoubtedly greatly increase the turning radius. Isn't this a dead end?
Both Wang Li and Bi Lin have said before that because the distance between the two sides of the canyon is too close, the plane has to hit the hillside as soon as it turns.But instead of increasing the slope and reducing the radius, Xu Cang turns with a small slope. Isn't that the opposite?
However, Xu Cang's move brought about a very serious consequence.That is, in the case of a single engine, the power of the aircraft is insufficient, Xu Cang forced the lever, and the rate of ascent was increased, but the power provided by the engine was not enough to maintain the rate of ascent, and the speed that had just stabilized began to drop again.
However, the speed was maintained above 230 knots before, so a slight drop in altitude is actually okay.Therefore, during the time of losing speed, Chen Guoli can be regarded as calm.
However, he soon discovered a problem.Because Xu Cang took the stick too hard, the plane suddenly formed an ascent rate of nearly [-] feet per minute, and in a short time, the plane rose more than [-] feet.
However, judging from the terrain display, the mountain to be crossed before is still in red, so it seems that its highest point is still more than [-] feet higher than the plane.Apparently, Chen Guoli's estimate of the climb height is still missing.
Previously, Chen Guoli felt that the plane would be able to climb over the mountain if it climbed more than 2000 feet.But now it seems that it may be more than three thousand feet,
There is no way, the time of ascent was wasted in the previous period, and even fell a little. The pressure of the ascent is all concentrated up to now, which is indeed too much pressure.
However, if you can maintain an ascent rate of more than [-] feet, you may still have a try.However, this height increase is at the cost of losing the speed of the aircraft. It is very likely that the aircraft will fall into a deep stall just after reaching the top of the mountain, and that is still a dead end.
Moreover, the most important thing is that Xu Cang didn't fly forward at all, but turned around.
wrong!As the nose of the plane turned slowly, Chen Guoli suddenly discovered that the plane was facing the gap in the mountain range.Could it be that Xu Cang is going to fly towards that mountain pass?But didn't Wang Li just say that after the mountain pass is the main line of Tianshan Mountain, once he enters it, he will die beyond death.
"Xu Cang, you can't go there, there are mountains behind!" Chen Guoli shouted loudly.
Could it be that Xu Cang was in a daze, he thought Xu Cang had some kind of clever plan, but he didn't expect to go into the main vein area of Tianshan Mountain!What kind of trick is this?
However, before Xu Cang could reply, Chen Guoli looked down and found that the airspeed of the plane was already lower than the UP speed.However, Xu Cang's hands kept moving, and he was still holding the stick backwards, so that the speed dropped continuously, and he was about to enter the yellow warning zone.
Chen Guoli's face changed drastically: "Xu Cang, don't take it anymore, you're going to shake the stick!"
What exactly is going on?Flying towards the mountain pass, recklessly taking the pole, this is Xu Cang's method, what is he going to do?
But at the moment when Chen Guoli's words stopped, Xu Cang suddenly leveled the plane, and the direction of its nose was obliquely facing the mountain pass.
The expression on Chen Guoli's face froze for an instant, and his heart almost stopped.
"Are you really going to fly to the mountain pass?"
However, the moment Chen Guoli had the idea, Xu Cang suddenly shouted: "EEC is hard to spare!"
Chen Guoli was taken aback. To be honest, he didn't understand 1 things, 1 things he didn't understand.With nearly 30 years of flying experience, he couldn't even touch the traces of Xu Cang's thinking.
Earlier, Chen Guoli was still questioning whether Xu Cang had lost his mind.But now, what Xu Cang said seems to indicate that everything is far from that simple.
"Okay!" Chen Guoli is a bit nice, he doesn't understand what Xu Cang is going to do, he will question and be puzzled, but when Xu Cang gives the order clearly, Chen Guoli will still do it without hesitation!
Sure enough, after hesitating in the blink of an eye, Chen Guoli no longer had any doubts, but directly took off his seat belt, got up and pressed the EEC control switch on the rear roof.
EEC switch, that is, full-efficiency digital engine control switch.This switch is only available in the NG series, the previous 737-300 and 737-500 models are not this switch, but the PMC switch in the same position.
The shape and appearance of these two switches are very similar, but their functions are not the same.
The EEC switch is a very typical two-channel switch, which is similar to auto boost, speed trim, Mach trim, etc.Any one of these channels can theoretically undertake independent work.Under normal circumstances, the two channels are switched to each other, and the switching node is every time the engine starts or tries to start.
In normal mode, the EEC calculates an N1 value based on the position of the thrust lever, temperature, pressure and bleed air load.However, sometimes there is a deviation between the actual N1 and the calculated N1. At this time, the EEC will adjust the fuel flow to make the two consistent.
At the same time, EEC can also provide functions such as idle control, flameout protection and ground start protection.
However, in some cases, the working channel of the EEC fails. The EEC will automatically switch to the soft standby state, and the ALTN and ON lights will be on at this time.
At this moment, EEC will use the last effective flight status to define the power parameters, so as to ensure that the engine power will not change when the mode is changed.
However, if the thrust levers are retracted to idle, or a new standby mode is manually selected, the soft standby mode will cease to function.
The standby mode can be changed to hard standby by pressing the EEC switch, and the ALTN light is off at this moment.In hard standby mode, the EEC is referenced to thrust lever position and internal data.
When manually selecting the hard standby mode, the thrust handle needs to be placed in the middle position first, because in the hard standby mode, its thrust is always greater than or equal to the thrust in the normal mode.
However, when Xu Cang asked Chen Guoli to manually select the EEC hard standby mode, the position of the thrust handle was at the front.Based on the thrust logic in hard standby mode, when the thrust handle is placed at the front, the relevant engine will obtain the limit N1 exceeding the maximum thrust in normal mode!
Just when Chen Guoli pressed the EEC switch, the No. [-] engine was like a wild horse running wild.
It's just that in that moment, the N1 value has rushed to an unprecedented 105%!
You should know that the limit of N1 is between 102% and 105%. As long as it exceeds 105%, it will easily cause the engine to exceed the limit.In other words, at this moment, the No. [-] engine has reached the edge of overrun.
However, with such a surge of thrust, the aircraft's rate of ascent directly exceeded [-] feet per minute.
When Chen Guoli chose hard backup, he didn't pay attention to the position of the thrust handle at all.After pressing the EEC switch this time, he lowered his head and noticed that Xu Cang had pushed the thrust handle of the No. [-] engine to the front.
All of a sudden, Chen Guoli's scalp was numb: "Xu Cang, the second serve is about to exceed the limit!"
"in spite of!"
While Xu Cang was speaking, he continued to raise his head, and finally the speed dropped below the UP speed, and he had already entered the yellow warning zone.The moment the speed indicator entered the yellow warning zone, the pitch limit indicator appeared on the PFD central attitude indicator.
Chen Guoli's face turned pale, and he shouted: "The speed is in the yellow zone!"
"I don't care what I said!" Xu Cang roared: "The spare flap release switch is in the preset position, and the spare flap position switch is tapped once, and the leading edge device is fully deployed!"
Chen Guoli's mind is really blank at the moment, the spare flaps are basically used when the trailing edge flaps are inconsistent, but they are still in a clean state, so why use the spare flaps.
However, there is a function of the spare flap extension, which is to extend the leading edge unit alone without touching the trailing edge flap.Because the leading edge device is linked with the trailing edge flap, only this method can release the leading edge device independently.
If the standby flap position switch is pressed continuously for a long time, the trailing edge flap will also be released, so it can only be tapped lightly.
"Do whatever you want!"
Chen Guoli also roared. At this moment, his mind was muddled, but he still obeyed the previous promise, he would do whatever Xu Cang said.
The spare flap switch is on the upper left of the front roof. Fortunately, Chen Guoli has not fastened his seat belt yet, so he gets up and opens the red cover of the spare flap switch, then pre-positions the switch, and finally taps Depress the right alternate flap position switch.
"All right!"
Just as Chen Guoli spoke, suddenly there was a shaking of the stick in his ears.In an instant, the hairs of Chen Guoli's whole body exploded, and he looked down at the airspeed indicator, and sure enough, the speed had entered the red and black speed zone, and Xu Cang's right hand holding the steering wheel was also shaking continuously with the shaking of the stick.
However, what made Chen Guoli feel unbelievable was that Xu Cang was still holding the stick, so that the speed of the plane continued to decrease.
"You are crazy, you are still holding the stick after stalling!"
Pushing the stick to reduce the aircraft's angle of attack during a stall is almost in the pilot's DNA.But now that the plane is shaking its stick, Xu Cang is still using the stick to increase the angle of attack. Isn't this adding fuel to the fire?
When it comes to instinctive things, Chen Guoli subconsciously wants to intervene and manipulate.However, Xu Cang shouted in a low voice: "The stick is shaken, but is it stalled?"
This short sentence struck Chen Guoli's heart like a thunderbolt.
That's right, the speed of the plane is almost [-] knots below the red and black speed bands, and the plane's ground speed is less than [-] knots, but Xu Cang is still pulling the stick backwards, and Chen Guoli is almost lying flat He stared straight at the gray sky.
"How did this happen, how did this happen, why hasn't the nose of the plane dropped yet?" Chen Guoli almost screamed, and such phenomena had already surpassed his cognition.
Aircraft stick shake is not equal to a real stall, Chen Guoli is fully aware of this.Due to the stall margin, the stick shaker speed is approximately 1.3 times the stall speed.
That is to say, if the aircraft will really stall when the speed is lower than 130 knots, but in fact, the stick shake warning will appear after the aircraft speed is lower than [-] knots.
The interval of [-] knots is the safety margin given to the crew.
But now this speed is too low, the true airspeed is barely better, and the ground speed has been reduced by less than [-] knots. Even so, the nose of the plane has not yet dropped.
Once the aircraft enters a deep stall, the airflow on the surface of the wing will completely separate from the wing, so the lift force disappears, and the aircraft just bows its head and falls straight down like an iron bump.But now, the plane doesn't seem to have lost its lift.
what is this?Why hasn't the airflow separated yet, and why does lift still exist?
However, Xu Cang didn't explain it to Chen Guoli at all, and when Chen Guoli was thinking wildly, the nose of the plane, which was raised beyond the limit, started to rotate to the left at a huge elevation angle, and the whole plane was a bit like a pendulum.
In fact, the plane does not really hover in the air, at least no large-scale civil aviation company can do the hovering operation.It's just that the aircraft's speed is extremely low at this moment, so that its turning radius is very small, which is a bit similar to turning without radius.
Chen Guoli on the left noticed that the rudder under his feet was slightly stepped on the left rudder the moment he realized that the nose of the plane was turning.Naturally, this was not his action, but Xu Cang's stepping on it.
However, to be precise, it is not stepping on, but releasing the right rudder.Because the No. [-] engine stalled, Xu Cang naturally had to keep the input of the right rudder to eliminate the sideslip caused by the unbalanced thrust.
Therefore, as long as Xu Cang releases the right rudder slightly, the plane will turn left naturally.
Chen Guoli can understand the operation of turning the nose of the aircraft.What he didn't understand was why the nose of the plane hadn't dropped, and why the airflow hadn't separated.
However, in any case, it doesn't matter whether Chen Guoli can understand it or not.Since the speed of the aircraft has dropped to an unbelievable level, the turning radius of the aircraft has been reduced to an equally unimaginable level.
In just a moment, the nose of the plane turned over more than 90 degrees.When the nose of the plane passed the mountain pass, Chen Guoli looked at the gap in the mountain range that looked like a gate of heaven, and a flash of inspiration suddenly flashed in his mind, and he seemed to understand.
"It's the wind, the strong wind!"
The essence of a stall is that the airflow is separated from the wing surface due to the excessive angle of attack, which is a basic flight principle.Only certain fighter jets can achieve post-stall maneuvers due to vector thrust and special starting layout, but large civil aviation airliners absolutely cannot, at least it is absolutely impossible to form such an exaggerated elevation angle and such a terrible low speed to maintain maneuver control.
However, Xu Cang did it!
What he can do is to use the violent horizontal airflow from the mountain pass.
Thinking about it now, Xu Cang was turning left with a slight slope to level off, and the nose of the aircraft was roughly facing the mountain pass not to pass through the mountain pass, but to adjust the angle to obtain a relatively larger headwind air volume.
The essence of a stall is the angle of attack, but from the perspective of ordinary people, it is always felt that the root of the stall is the low speed.This is of course a one-sided concept, but the truth behind it is not entirely wrong.
Because when the aircraft is at a low speed, the speed of the airflow passing on the surface of the wing will also decrease, making it easier to separate from the wing performance, so that the lift force is reduced.
However, if the airflow itself has a huge velocity.Even if the speed of the aircraft is small, the relative speed is very high. Even at high angles of attack, the high-speed airflow can still press the airflow to fit the wing surface as much as possible.
The horizontal airflow with violent energy vented by the mountain pass is the source of the best high-speed airflow.Moreover, since the altitude of the aircraft is not very high at this moment, the air is not as thin as that at high altitudes, which can still give the aircraft a huge increase in aerodynamic performance.
If the same situation occurs at high altitude, the effect will be greatly reduced.
However, this is not enough!
Therefore, Xu Cang needs to switch the No. [-] engine to hard standby mode in order to obtain more extreme thrust.At the same time, the leading edge device is deployed to delay the flow separation.
Xu Cang is very clear-headed, he only needs the leading edge device, but not the trailing edge flap.Although flaps can increase lift, they will significantly increase the camber of the wing, making it easier to separate the airflow.
In other words, extending the trailing edge flaps will increase the stall speed, so it is necessary to avoid extending the trailing edge flaps.
Whether it is to use the airflow of the mountain pass, or to increase the thrust limit, or to expand the leading edge device, everything is to delay the separation of the airflow.
It was these preparations that made Xu Cang complete such a masterpiece!
For some reason, Chen Guoli remembered that he had gone to flight school abroad to fly a Cessna 152 several times.If you encounter a strong headwind in the air and do Power On Stall at the same time, just like Xu Cang at this moment, the plane maintains an extremely exaggerated elevation angle, but the plane does not speed.
Perhaps, the two are somewhat related.
But what is a Cessna 152 and what is a 737?Xu Cang was able to complete such a miraculous operation on this tens of tons behemoth, which simply broke through human cognition.
At this moment, Ji Dong and Wang Wen, who were filming on the top of the mountain, were the closest to the plane.At the beginning, Wang Wen was still focused on shooting, but when the plane rotated in an incredible way, he felt that his world view was about to collapse.
He is from the design institute, so he naturally knows some flying knowledge.But it is precisely because of the knowledge of flying that I feel how terrifying the scene in front of me is. Is this really the maneuver that an aircraft like 737 can fly out of?
"Brother, am I right?" Wang Wen almost shouted, "What the hell is going on?"
Ji Dong's mouth was slightly open, his mind was blank, everything in front of him had refreshed his cognition over and over again.Taking a deep breath, Ji Dong forcibly suppressed the throbbing in his heart, and picked up the walkie-talkie: "Tower, tower, can you see the plane? It's in the sky near the scheduled observation position."
In the tower control room, when everyone was still shocked by the fact that Xu Cang's plane signal was almost hovering, Ji Dong's voice came in.
Wang Li reacted first, ran to the corner of the control room, pulled out a telescope, and looked in the direction of the canyon.
Bi Lin was also very excited at this moment, and immediately walked to Wang Li's side: "Did you find it?"
It stands to reason that the plane cannot be seen from the tower side.However, because Xu Cang lifted the plane, Wang Li located the plane in the gap between the mountain peaks.
But when he saw the maneuvering state of the plane, his whole body was shocked, as if he had seen the most terrifying thing, and even the hand holding the binoculars was shaking.
"What's the matter?" Bi Lin saw Wang Li's appearance and knew that something must have happened, but Wang Li didn't say a word, and Bi Lin was so angry that he knocked on his crutch a few times.
Wang Li put down the binoculars slowly, his mouth was still half open, and it seemed that he still hadn't recovered.
Zhou Yanping also ran over and said anxiously, "Stationmaster Wang, what's the matter?"
Wang Li took a deep breath, his lips were trembling, his eyes were still a little dull, and after a while, he slowly turned to Bi Lin: "Old Bi, he...he turned around, as if he was hovering in the air."
"What did you say!?" Bi Lin turned pale with shock, "Impossible, how could 737 hover in the air, it's impossible!"
Zhou Yanping didn't speak, but he also felt that Wang Li was wrong, because it is absolutely impossible for the 737 to hover in the air, and it is not the kind of fighter jet that takes off and lands vertically.
"Stationmaster Wang"
What else did Zhou Yanping want to say.Suddenly, the tower controller said: "Station Master, the signal of 1533 has started to return."
As soon as this statement came out, everyone gathered in front of the radar screen, regardless of whether they were actually hovering in the air or not.Sure enough, at this moment, the signal point of the plane is slightly back than before.
All of a sudden, Zhou Yanping felt confused: "Is this really turning back?"
In the cockpit, Xu Cang was adjusting the input of the rudder. After the nose started to rotate, he no longer took the stick, but kept the pitch attitude unchanged.
With Chen Guoli on the side, he was already automatically unable to hold himself back, and Chen Guoli only felt honored to be able to experience such a miraculous operation in person.
As the nose is gradually turned back, the headwind volume begins to decrease.Xu Cang then began to reduce the attitude of the plane to prevent the plane from really entering a deep stall.
However, Xu Cang did not reduce the pitch attitude quickly, otherwise the plane would deviate too much from the programmed route due to turning, and problems would easily occur.However, when there was still about thirty degrees to turn, Xu Cang suddenly felt a little strange shaking of the steering wheel.In an instant, Xu Cang's face changed suddenly, it was really about to stall.
Fortunately, there were only [-] degrees left in the end. Xu Cang pushed down the steering wheel, and the nose of the plane immediately followed, and the lift rate suddenly decreased to a negative number.
"Call the program again!" Xu Cang was able to distract Chen Guoli while reducing the angle of attack.
Chen Guoli woke up instantly, without hesitation, he immediately operated on the CDU, and re-tuned the single-shot program.As the single-shot program appeared on the navigation page, Xu Cang immediately had a level reference.
Xu Cang's action of pushing the pole was rather inquisitive, and he did so while maintaining a high thrust.This is actually not very good, because too much thrust makes it easier for the plane to look up, and it is not easy to push the nose down.
However, in order to recover as soon as possible, Xu Cang naturally ignored these things.At the same time as the ejector rod, the main electric trim wheel rattles forward at the same time.
Recovering from the stall requires a loss of altitude. If it is at the programmed altitude, such a dive will cause serious accidents.However, Xu Cang raised the plane by almost [-] feet in the process of leading the stick.This height is just for Xu Cang to recover from the stall.
However, the stall Xu Cang encountered was already relatively deep, and two thousand feet was already relatively tense.Knowing this reason, Xu Cang had to use full thrust to recover from the stall, so as to control the lost height to the maximum.
It has to be said that Xu Cang's way of getting out of the stall is really like dancing with the tip of a knife.The attitude of the aircraft is right next to the pitch limit indicator, which is really not bad at all.
In this way, the altitude lost by the aircraft can be minimized.
In the end, Xu Cang re-adjusted the thrust and speed, and at the same time pushed the heading onto the programmed route, and the altitude was firmly fixed at the height limited by the program.
Looking at the direction of the turned nose, even for Xu Cang, it was full of pride.
It is this kind of turning the impossible into the possible that is the most exciting, and Xu Cang is this kind of person who turns things around.
Chen Guoli was also flushed with excitement, he didn't expect to survive, and Xu Cang found a chance of survival in the inevitable situation.
After turning on the horizontal navigation and automatic driving, Xu Cang couldn't control the surging pride in his heart anymore.Since Yulong Airport, he has never experienced this kind of feeling again, that kind of joyful feeling of grasping and controlling fate.
The sky has the intention of being unstoppable, but there is absolutely no way for Xu Cang to reverse the sky!
Xu Cang let go of the steering wheel with his right hand, and looked far away, looking at the outside world.At this moment, he only felt that the sky seemed to be a little shorter. At this moment, his ecstatic and fearless roar resounded through the entire sky: "I am indeed the strongest!"
Xu Cang's long whistle fell in Chen Guoli's ears, and he also felt his heart pounding.Living in this world, to reach Xu Cang's step, I really have no regrets.
Moreover, Xu Cang's move pointed out a way of survival for the latecomers in the desperate situation.
He really did it!
However, when the two fell into boundless joy, the EGT value of the No. [-] engine suddenly began to vibrate slightly, but none of this was seen by the two of them!
I don’t think it will be until evening tomorrow, and I may have to ask for leave, depending on the situation. I’ve been busy with work recently, and the update time is messy.
