"Where's Tongbo?" Xu Cang stretched out his hand and ticked Di Qingquan.
The captain on the left seat was dumbfounded when he saw Xu Cang's action. Xu Cang looked young, how could he be as old as Di Qingquan?However, Di Qingquan didn't think there was any problem, so he handed Xu Cang the paper tongbo clipped on the steering wheel.
The printers on the 737 of this era are far less compact and convenient than the later models, and the width of the printed notes is more than twice that of the printers of later generations.Moreover, the paper of the note is soft and easy to break, and it will be torn if you are not careful.After about seven or eight years, the printer on the 737 will undergo a large-scale reform, and even the printer paper will be upgraded.
After receiving the paper Tongbo handed over by Di Qingquan, Xu Cang looked at it for a while and then threw it on the central console: "The Tongbo said moderate rain, how can I tell the difference between heavy showers?"
In this era, everyone is not very concerned about landing standards under precipitation conditions.It doesn't matter if it's light rain or moderate rain, it just depends on whether you can see the runway at the end.
It’s just that generally speaking, moderate rain is acceptable in daytime conditions, but at night, moderate rain is more likely to affect the final visual reference.However, whether it is day or night, if there is heavy rain, it will be more difficult.Rainwater can directly form a layer of water covering on the windshield that cannot be wiped dry, even if the wiper is turned to a high position, the rainwater scraped off will be quickly filled by the rainwater behind, resulting in a reduction in visual ability.
Of all the levels of precipitation, however, showers are special.The determination of the shower has always been very vague. Should it be determined according to the highest level of the reported shower, or should it be ignored and completely rely on the visual judgment of the crew?
For example, heavy showers, some people think that it should be directly identified as heavy rain, or whether heavy showers are not applicable to the unified precipitation standard depends on whether the crew can obtain visual reference at the decision height and continue to obtain suitable visual observation at the following heights .
Some people may think why there is a need to set standards, and in the end, it is not good to only rely on the visual judgment of the crew?Needless to say, the variable weather of showers, even if it is reported stable precipitation, such as moderate rain.
The distribution of rainwater is not uniform, and it may be denser in some areas and slightly weaker in others.In weaker areas, it actually has no effect on landing.
In this way, why should there be a hard limit on landing?It is based on this concept that even though many airlines have landing regulations under precipitation conditions, the actual flight implementation is not strict.
The main reason is that based on the pilot's excessive autonomy, it is easy to lead to the possibility of some forced landings, which will undoubtedly increase hidden dangers.Pilots are human too, and no pilot is willing to make an alternate landing. This often leads to the pilot's subjective desire to land when encountering marginal weather, which is the so-called preset position, so that the pilot forms a "pipeline effect".
Once the pipe effect is formed, the pilot's field of vision will become narrow.The field of vision here is not the scope of vision in a narrow sense, but the breadth of thinking and observation.Begin to subjectively ignore the unfavorable factors that affect the landing, and only want to land, and in the end it is easy to cause a security threat.
It is precisely based on this consideration that the bureau gradually withdrew the pilot's right of self-determination in the later period, and even did not give the crew the opportunity to approach under certain weather conditions.
Of course, the formulation of precipitation standards in later generations was overkill, and even Xu Cang felt that it was a bit complicated.Not only are there different restrictions on the different precipitation intensities, but even different regulations are made according to the length and level of the runway of the landing airport.In addition, there are different regulations for taking off, landing, or taking off and landing in day and night.
However, no matter how the regulations of later generations change, or whether they are strict or not, basically they cannot fall to the ground in heavy rain.Even in today's relaxed era, if the tower clearly reports heavy rain and the crew lands in the end, then the company will investigate afterwards.
"As soon as I transferred to the Hanjing district, I informed us of the latest situation. It has been steady and moderate rain before, but recently the rain has been very unstable, with moderate rain for a while and heavy showers for a while." Di Qingquan said to Bei It doesn't feel special not to make an alternate landing. Anyway, if an alternate landing is made, there is a high probability that it will be alternated to Jinmen.Jinmen is very close to Hanjing. If you really can't get up after the alternate landing, you can take a car to Hanjing by land.
Di Qingquan recalled: "What did the Hanjing District Commissioner say just now, that there are eleven planes circling in this field? Now the approach area is basically full, and there is no room for extra circling. Hanjing's It means to let us decide in advance whether to continue the approach or circle. If it is a circle, they need to guide us to the east of Jinmen in advance, only there is still airspace for waiting."
"It's all crowded to the east of Jinmen?" Xu Cang was stunned: "Is there going to be a plane coming in from behind?"
"What do you think? Hanking has more than 300 flights a day. Is it an exaggeration to squeeze more than a dozen flights now? Besides, the flights at Jinmen Airport are also very busy. If you wait a little longer, the east of Jinmen will not be able to circle around. I guess We're going to circle around the Bohai Sea." Di Qingquan said with a smile.
"What the hell?" Xu Cang himself was unwilling to make an alternate landing.Once a hub airport like Hanjing closes the airport due to weather reasons, the flights will be collectively diverted. Once the diversion is made, it is very likely that they will not be able to get up: "How is the weather in Jinmen?"
However, Di Qingquan was on the plane, so let him talk to the leader of the Air Traffic Management Bureau, maybe he can go through the back door.In the civil aviation industry, whether it is relevant or not is a completely different concept.
"Jinmen?" Di Qingquan raised his chin at the captain of the left seat: "What's the weather like in Jinmen?"
The captain quickly replied: "I read the METAR report just now, and the weather in Jinmen is very good. As for the TAF report, there is no saying that the weather will get worse."
"That means the weather is very stable." Xu Cang fell into deep thought: "The weather in Hanjing is really difficult, not to mention the precipitation, the vertical visibility is only [-], which is a bit difficult to handle. The rain can reduce the vertical visibility. It’s very rare to reach two hundred. If you really have to go around the Bohai Sea, it’s better to go directly to Jinmen.”
Generally speaking, visibility is better when it rains.But for some reason, it was written on Tongbo just now that the vertical visibility of Hanjing Airport is only [-] feet, and the decision height for blind landing is generally [-] feet. The two basically overlap, which is more difficult.
The captain turned his head and asked Xiadi Qingquan: "Master, what shall we say?"
He is indeed the captain in charge, but it is not his turn to make a decision now.
However, Di Qingquan did not answer, but turned to look at Xu Cang: "What do you say?"
"Let's go, isn't Shandong Airlines approaching in front, let's follow him, what's the point of waiting?" Xu Cang smiled and said, "It's good to have someone take the lead."
When it comes to Shandong Airlines, even the captain who has been suppressing himself will smile: "Shandong Airlines, it's normal."
"Yes!" Xu Cang also laughed, but Di Qingquan was quite helpless.
Shandong Airlines, namely Shandong Airlines, is known as the airline company's flat-headed brother, the flying iron-headed boy, the reckless man among reckless men, the one with [-]% purity, and is often ridiculed by industry personnel as the Shandong branch of Russian Airlines.
It often happens that an airport encounters some extreme weather, which leads to a large number of flight cancellations. As a result, Shandong Airlines' flights not only did not cancel, but finally landed early.
As for the reputation of Shandong Airlines, the Civil Aviation Administration of China knows a thing or two, and once reminded Shandong Airlines to rectify the style of the fleet.
As a result, Shandong Airlines agreed to it in front of it, but still went its own way when it turned back, and directly ignored the warning from the bureau.Although Shandong Airlines has a relatively "tough" style of work, there have never been any major safety problems. Even though the bureau was helpless, it did not force it too much, and finally let it go.
In fact, after more than ten years, until Xu Cang became the chief engineer of the Civil Aviation Administration, the style of Shandong Airlines has not been restrained, so that it has become a "world order me" with Aeroflot!
The marginal weather like Hanjing is quite annoying for the pilots, because although the go-around is a normal operation procedure, it contains a lot of warning items, and if there is a slight mistake, it is a lot of hard warnings.Therefore, unless there is a relatively high degree of certainty, the pilot will not conduct an approach with a high probability of going around.
In this kind of situation where you can fall or fall, there is an urgent need for a "brave" to break the deadlock.Regardless of the fact that there are eleven planes circling and waiting in the sky, as soon as the Shandong Airlines plane successfully lands, all eleven planes will have to announce their approach.
"Don't you need to wait?" the captain asked, "Let's see if the Shandong Airlines can land?"
"Wait until the Shandong Airlines lands, isn't it that our day lilies will be cold? If we wait for the Shandong Airlines to land, we will be No. 12. Let's go!" Di Qingquan made a final decision.
The chief engineer of the General Administration has said so, the captain will definitely not have any objections, and quickly reported to the Hanjing District: "National University 1344, we apply to continue the approach."
Soon, the Hanjing District Commissioner gave a reply: "National University 1344 received it, you are now at an altitude of 4000 and 030 meters, and the approach is guided by radar. Turn right and head to [-], and enter the port from the east."
The weather conditions can also be seen on the approach radar, but not as accurately as the crew's airborne radar.Normally speaking, people like Xu Cang who enter the port from the south are unlikely to enter the port from the east, because it will affect the departing aircraft.However, it seems that there are no planes leaving the field now, so there is no scruples.From the airborne radar, there is a lot of weather coverage to the west and south of the approach area.
This is just a higher and farther scan result.Generally speaking, when the altitude of the plane goes down and it gets closer, more weather will be scanned.From this point of view, the incoming planes should also enter from the east.
It’s just that Jinmen is to the east of Hanjing, and if you wait a little longer, Jinmen has reached the peak of entering the port, and the entry into the port on the east side will also be restricted.
"The altitude is 4000 and 030 meters, turn right and heading 1344, National University [-]!" the captain replied.
It is estimated that with the encouragement of Xu Cang and others, the other planes that were still hesitating in the same channel all began to ask to join the approach one after another.That's the pilot, and at some point the same herd.
When he started to turn right to join the approach, Xu Cang yawned: "Just now I saw that the wind direction has changed a lot, and the wind speed is 11 meters. It must be wind shear, right?"
The captain's face turned black all of a sudden. If windshear was encountered in marginal weather, it would not be an extremely difficult matter.
"Can you stop the crow's mouth!" Di Qingquan said speechlessly.
Pilots can be quite superstitious at certain times.
Xu Cang smiled, didn't say anything more, stretched his waist, and began to close his eyes to rest his mind again.
At this moment, in the cockpit of Shandong Airlines flight 5112, which is the first to approach, the captain Deng Wenjia is nestling in his seat leisurely, still mocking the eleven planes that were circling just now.
"So the standard for being a captain is still too low now, and they are all afraid of approaching due to marginal weather. What kind of captain is this?" Deng Wenjia sneered: "No, we have to get up Head, give them a sample."
Because it was a lead flight, the co-pilot was in control of the plane at this time, so Deng Wenjia could be so relaxed. He only had to be responsible for monitoring whether the co-pilot made any mistakes or omissions.
At this time, the plane is in the period of radar guidance, just follow the requirements of the control to lower the altitude and adjust the heading. The only thing the co-pilot has to spend brain cells is to make a deceleration plan in his mind. Deng Wenjia's chat.
"Shandong Airlines has been established for more than a year. Isn't it because of this hard work that it develops so fast?" The co-pilot said with a smile: "Other companies are all about rules and regulations, and we don't have so many requirements. We only want a safety and make money."
Deng Wenjia patted the visor: "That's the reason. What's the use of making so many rules? Isn't civil aviation just for safety and making money? What landing standards are there under precipitation conditions? This is clearly to limit the crew's subjective initiative. Let me say, Except for Shandong Airlines, everyone including the three major airlines are mediocre.”
Since the reorganization last year, Shandong Airlines has risen at an incredible speed. In this glory, being a member of Shandong Airlines naturally gives rise to some feelings of pride, and even began to underestimate the heroes of the world.
"Mr. Deng, if you put it in the past, I think what you said is quite reasonable. But now I think it is a bit biased."
Deng Wenjia is not just a pilot in Shandong Airlines, he has an administrative position, and it is not low.But the co-pilot who has no background and no power dares to refute Deng Wenjia. This is certainly related to Deng Wenjia's good temper, but it is also a good glimpse of the overall atmosphere of Shandong Airlines.
Deng Wenjia raised his eyelids: "How to say?"
The co-pilot still focused most of his energy on the aircraft instruments, and only allocated part of his energy to chatting with Deng Wenjia: "Some time ago, didn't something happen to Blue Sky Airlines in Southwest China? There was a problem with the 747 leased from Muhua Airlines. As a result, the doors of the air hatch opened."
"That!" Hearing this, Deng Wenjia slightly restrained his arrogant expression: "9811!"
"That's right, it's 9811! Mr. Deng, you should have more detailed information. It's true, as rumored, the crew flew back blindly. Is this something humans can do?" Obviously, the co-pilot was also interested in 9811. He was very interested in the incident, as if he wanted to take this opportunity to solicit gossip from Deng Wenjia: "Usually there are some safety issues, and the company has already organized a study, why is there no news at all this time?"
"You mean organizational learning?" Deng Wenjia asked.
"That's right!" The co-pilot replied: "By the way, let us understand the specific details. There is no news at all, and it's all rumors."
"Organization study?" Deng Wenjia sneered, "What do you study?"
The co-pilot was stunned: "Just to learn from the handling experience of the crew at that time!"
"We deserve him too?" Deng Wenjia sighed, "The bureau made a conclusion on the person who manipulated this matter the next day."
"So fast?" The co-pilot exclaimed, "Isn't it too fast, such a big matter can't be concluded for a month?"
Deng Wenjia smiled and said, "Let me tell you this, the person from Blue Sky Airlines is really flying blind, completely blind, he can hardly hear or see! If you can't fly under the circumstances, you said let them investigate, do they have the face to investigate?"
"It's really blind flying!" Even though he had heard the rumors before, but it was confirmed from Deng Wenjia's mouth, the co-pilot still found it incredible: "I can't see or hear, how can I fly?"
"I don't know the details. It seems that a flight attendant next to me helped me, maybe she gave some simple reminders! But you should also know that when we fly, it's like a mountain, and the flight attendants don't see each other when they go in." How much more useful than ordinary people. So, I feel that most of it depends on that person.” Deng Wenjia sighed: “You are right, if you say mediocrity, that person is definitely not. Seriously, Blue Sky Airlines’ poor settlement can produce such What a genius, it really is smoke from the ancestral grave."
The co-pilot smiled and said, "I think that person is very reckless in operating the plane, but it fits our company's temperament very well. If he can come to our company, it will be a perfect match."
"It's a pity!" Deng Wenjia curled his lips: "It seems that Blue Sky Airlines is going to die."
As he said that, the voice of Hanking’s approach came from the radio: “Shandong Airlines 5112, you can turn left and heading 230, descend to an altitude of 1000 for two hundred meters, establish a blind landing on runway 18, and report the course!”
"Turn left to heading 230, descend to an altitude of 1000 for two hundred meters, establish a blind landing on runway 18, track report." The co-pilot quickly regained his composure and repeated.
When the co-pilot adjusted the altitude and heading, Deng Wenjia sat up straight, turned his neck, and muttered: "Oh, stop talking, work!"
As the plane cut into the localizer, after notifying Hanking of the approach, the approach commanded the Shandong Airlines crew to turn to the Hanking tower.
"Hanking Tower, Shandong Airlines 5112, runway 18 is on the waterway."
"Shandong Airlines 5112, continue the blind landing approach to runway 18, complete blind landing report."
"Completely blind report, Shandong Airlines 5112!"
A full ILS means waiting until the glideslope is also intercepted.
At this time, Hanking Tower began to report the live situation to the Shandong Airlines crew, which is considered a normal operation under special weather.
"Shandong Airlines 5112, it's raining in this field, the runway is wet, the ground wind is 11 meters, the vertical visibility is 100, the RVR is 900, 1000, 1009, and the corrected sea pressure is [-]. Is it acceptable?"
The co-pilot didn't answer, but glanced at Deng Wenjia.Deng Wenjia nodded, and the co-pilot replied: "We have no problem."
"Okay!" Hanking Tower received a reply from the crew, and just said: "Shandong Airlines 5112, complete blind report."
"Completely blind report!"
After the briefing was completed, Deng Wenjia clicked his lips and looked at the co-pilot with a smile: "Are you confident?"
The co-pilot smiled wryly: "If it's only moderate rain, I think I'm fine. But the 11-meter wind is uncertain, Mr. Deng, why don't you come!"
"Although I think the co-pilot should be tempered, it is really too difficult to superimpose 11 meters of uncertain wind on the edge of the weather, so let me do it." After speaking, Deng Wenjia switched the main guide from the right to the left, and took a picture Pat the co-pilot on the shoulder: "I took your landing today, tell the planning room later, let me fly with you, I have to return the landing."
The co-pilot nodded: "Then I will remember."
After the descent track was intercepted, the FMA mode was changed to G/S, and the co-pilot notified the complete blind landing.
"Shandong Airlines 5112, this field is moderately rainy, the runway is wet, the ground wind is 11 meters, the sea pressure is corrected to 1009, the runway 18 can land, pay attention to the airflow from all sides." The control tower quickly gave the landing permission.
Correct sea pressure 1009, runway 18 can land, Shandong Airlines 5112. "
After the co-pilot finished reading back, Deng Wenjia added: "Tower, if I go around in a while, apply to deviate from the standard go-around procedure and turn right immediately."
If you follow the standard go-around procedure for runway 18, you need to keep to one side for a go-around, and turn right after the altitude reaches 400 meters.However, judging from the weather radar, there is some weather on the side of runway 18. If possible, I still hope to turn right as soon as possible.
"Shandong Airlines 5112, if you go around, you can turn right immediately."
"Okay, thank you!" Deng Wenjia thanked, and immediately began to habitually wipe his hands with a towel. This is the habit of many pilots. Before landing, wipe off the sweat on the palm of his hand, so as not to affect the feel of the lever: " Pay attention to reporting deviation data in a while, and the wipers listen to my password!"
The height is still high now, and there is no need to turn on the wipers for the time being.Generally speaking, it is not necessary to turn on the wipers before turning to the visual stage.However, there is no fixed requirement for this thing, and it is estimated that when to open it is mostly according to the meaning of the crew.
"Okay!" The co-pilot was also a high-ranking officer, and he was familiar with this kind of thing for a long time, so he quickly agreed.
Deng Wenjia adjusted the height of the seat slightly after wiping the sweat from his hands. In this marginal weather, it is better to adjust the height of the seat a little higher than usual.During the descent phase, Deng Wenjia kept the autopilot switched on. This is not because Deng Wenjia is not confident in his control ability, but because there is no need to switch to manual control too early in marginal weather. Of course, this is when the aircraft is not in good condition. subject to major changes.
This is to free up extra energy to find the runway and not miss the visual reference.
This kind of marginal weather combined with relatively obvious unstable wind is still quite difficult for many pilots, but Deng Wenjia has never seen it on any occasion, and I don’t know how many times it has flown even more difficult than this. scene?
"Altitude [-] feet, steady approach!" The co-pilot reported.
However, just as Deng Wenjia adjusted everything and put his right hand on the throttle lever, he suddenly noticed that the wind direction and wind speed display at the corner of the navigation page began to produce very bizarre changes.
Before Deng Wenjia could react, the plane suddenly lowered its head. Deng Wenjia instinctively overtook the auto throttle, turned off the throttle, and shouted: "What the hell?"
In the cockpit of China National Airlines, it is not as easy as that of Shandong Airlines in front. Di Qingquan is a serious person, Xu Cang is too lazy to speak, and the captain is afraid to speak, which makes the atmosphere in the cockpit a little bit A little stiff.
Xu Cang himself didn't like this kind of atmosphere, but this time he didn't need to fly, he just lay back, closed his eyes, and didn't care about anything.
As the aircraft cut to final and intercepted the localizer, the frequency was transferred to the Hanking Tower.As before, the Hanking tower reported the precipitation and wind direction and speed of the field, and the content was exactly the same as that reported to Shandong Airlines 5112.
After repeating the recitation, Xu Cang felt a little lucky, but fortunately, he finally stabilized in Zhongyu.If the report is a heavy shower, then there is some trouble.
Moderate rain, the vertical visibility was at the marginal value, and the wind was 11 meters, which was a relatively difficult landing condition, so that Di Qingquan asked the captain if he wanted to fly.
How could the captain dare to let Di Qingquan fly, he said quickly: "Chief Master, no need, I can handle this."
"Really sure?" Di Qingquan asked suspiciously: "Don't worry, this landing is not within the scope of supervision, so don't be nervous. If you feel unsure, just let me fly."
In fact, Di Qingquan's idea is also very simple, he just wants to land, and he doesn't want to divert.Now that the weather conditions are in line with the standard, he can't think of going around because of the technical reasons of the pilot.Now there are more than a dozen planes following them. If they go around and add other planes coming over during the approach phase, they will have to wait in the sky until the Year of the Monkey.
Captain: "Chief, I know, I have no problem with this."
"Well, that's fine!" Di Qingquan still respected the captain, since the captain said there was no problem, he still chose to believe it.He has inspected many captains of National Airlines, and the overall impression is good: "Okay, then you fly. Remember, don't pursue lightness, come to a solid landing."
Di Qingquan was worried that in order to impress him, the captain purposely landed lightly, which violated the principle of landing on a wet runway, and would cause trouble if the plane skidded.
"I know, I know!" The captain was still struggling with this matter just now.Of course he knew that when there was a lot of rain, he had to land firmly, but he was worried that it would make Di Qingquan mistakenly think that it was a heavy landing, so he had a bad association with himself.
Now that Di Qingquan spoke up by himself, there was no need to worry.
Di Qingquan's message to relieve the captain's mental burden is still somewhat useful, at least Xu Cang's body is not so tense behind him, otherwise Xu Cang would feel very uncomfortable just looking at the captain's sitting posture.
Xu Cang is not worried about this landing. A person who can be a captain should be a bit real, and looking at the assignment book hanging, this captain is not just a single-pilot captain, but an instructor. The experience is also relatively sophisticated and can be trusted.
He yawned, and seeing that he was about to hit the ground, he sat up a little bit and pulled himself together.Although it has nothing to do with me, it seems impolite to still sleep after landing.
However, I was really lucky today. Precipitation, vertical visibility, and wind direction and speed are all critical, and if any one exceeds the standard, I will not be able to fall.
At this moment, the control tower reminded again: "National University 1344, the front aircraft reported that the airflow changes sharply below the altitude of [-] feet, please pay special attention."
The captain was stunned: "Has the windshear warning been triggered? Is the plane in front of it a Shandong Airlines plane? Has it landed?"
"The crew did not report that the windshear was triggered, and now the Shandong Airlines plane has landed normally."
"That's fine, let's continue approaching, thank you!"
Windshear falls under the category of mandatory reporting, and as long as it is triggered, the crew should report it to the control.Since there was no report from Shandong Airlines, it seems that no wind shear was encountered.
The only thing the captain is more worried about is wind shear, if it is just unstable airflow, it is quite acceptable.
"If it's below 800 feet, doesn't that mean we've arrived?" The captain looked at the altimeter, and now there are only more than [-] feet left above the ground.However, from the perspective of perception, there is some shaking of the plane, but the magnitude is not very large.
Even Di Qingquan, who was on the side, said with a relaxed expression: "It seems that we are lucky, and that part of the turbulence drifted away?"
The captain was still on autopilot at this time, and he was more concerned about looking for visual references. The stability of his body made him feel that the airflow on the final side should not be as strong as the previous aircraft reported.
However, Xu Cang's expression in the back gradually became serious, because he clearly saw the wind direction at the corner of the aircraft's navigation ND changing at an extremely fast speed.
Originally, the plane was facing the headwind, but in less than two seconds, the wind seemed to circle, and the wind direction quickly switched from headwind to tailwind.
Xu Cang's expression changed, and just as he was about to remind the captain, the airspeed kept dropping like a deflated ball.The captain didn't notice the change in wind direction, but he saw the change in airspeed, and his first thought was to intervene in the autothrottle to make up some thrust.
Because Boeing's autothrottle response is relatively slow, human intervention is often required in order to maintain speed accuracy in turbulent conditions.
At this time, the captain still believed that the aircraft was only a matter of speed.But after he pushed the accelerator up, the speed of the plane did not stop.He was stunned for a moment, and then added a little bit of accelerator, but what greeted him was "windshear" warnings!
"Wind Shear!"
The captain yelled, and almost reflexively executed the windshear recovery maneuver.Accelerate, press TO/GA, disconnect the autothrottle, use maximum thrust, start at [-] degrees, and follow the flight guidance.
However, he didn't miss the previous actions such as increasing the gas pedal to the maximum, but at the moment when he started to lift, the plane's already low speed suddenly slowed down, and the speed fell directly into the red zone, and the steering wheel began to move crazily. Shaking up, everyone's ears were filled with the warning sound of shaking the stick.
The moment the plane shook the stick, Di Qingquan's expression tightened, and he was ready to intervene.At such a low altitude, if the plane stalls, wouldn't it all be over.
Like Di Qingquan, the captain's reaction was also the same, he was going to put a little pressure on the game first.
However, the moment the captain wanted to push the rod, a hand stuck out from behind, firmly restraining the captain's movement.The captain was startled, turned his head to look, but saw Xu Cang's gloomy face, and asked back: "What do you want to do?"
PS——The latter part is in the author's words below.
The captain's complexion changed, and he suddenly exclaimed: "Xu Cang?"
However, Xu Cang didn't pay any attention to it, and ignored the captain at all. At this critical moment, Xu Cang didn't push the shot, instead, he took the down shot slightly.
However, this action directly made the captain's hairs stand on end, and he clasped Xu Cang's wrist with his right hand, and shouted: "The plane has stalled, are you still carrying the stick?"
Xu Cang said coldly: "Do you really know how to fly a plane? Now at such a low altitude, if you dare to push the pole, put your aim above the pitch limit indicator. Can you do it? If you can't, then let I'm going to fly!"
(End of this chapter)
"Where's Tongbo?" Xu Cang stretched out his hand and ticked Di Qingquan.
The captain on the left seat was dumbfounded when he saw Xu Cang's action. Xu Cang looked young, how could he be as old as Di Qingquan?However, Di Qingquan didn't think there was any problem, so he handed Xu Cang the paper tongbo clipped on the steering wheel.
The printers on the 737 of this era are far less compact and convenient than the later models, and the width of the printed notes is more than twice that of the printers of later generations.Moreover, the paper of the note is soft and easy to break, and it will be torn if you are not careful.After about seven or eight years, the printer on the 737 will undergo a large-scale reform, and even the printer paper will be upgraded.
After receiving the paper Tongbo handed over by Di Qingquan, Xu Cang looked at it for a while and then threw it on the central console: "The Tongbo said moderate rain, how can I tell the difference between heavy showers?"
In this era, everyone is not very concerned about landing standards under precipitation conditions.It doesn't matter if it's light rain or moderate rain, it just depends on whether you can see the runway at the end.
It’s just that generally speaking, moderate rain is acceptable in daytime conditions, but at night, moderate rain is more likely to affect the final visual reference.However, whether it is day or night, if there is heavy rain, it will be more difficult.Rainwater can directly form a layer of water covering on the windshield that cannot be wiped dry, even if the wiper is turned to a high position, the rainwater scraped off will be quickly filled by the rainwater behind, resulting in a reduction in visual ability.
Of all the levels of precipitation, however, showers are special.The determination of the shower has always been very vague. Should it be determined according to the highest level of the reported shower, or should it be ignored and completely rely on the visual judgment of the crew?
For example, heavy showers, some people think that it should be directly identified as heavy rain, or whether heavy showers are not applicable to the unified precipitation standard depends on whether the crew can obtain visual reference at the decision height and continue to obtain suitable visual observation at the following heights .
Some people may think why there is a need to set standards, and in the end, it is not good to only rely on the visual judgment of the crew?Needless to say, the variable weather of showers, even if it is reported stable precipitation, such as moderate rain.
The distribution of rainwater is not uniform, and it may be denser in some areas and slightly weaker in others.In weaker areas, it actually has no effect on landing.
In this way, why should there be a hard limit on landing?It is based on this concept that even though many airlines have landing regulations under precipitation conditions, the actual flight implementation is not strict.
The main reason is that based on the pilot's excessive autonomy, it is easy to lead to the possibility of some forced landings, which will undoubtedly increase hidden dangers.Pilots are human too, and no pilot is willing to make an alternate landing. This often leads to the pilot's subjective desire to land when encountering marginal weather, which is the so-called preset position, so that the pilot forms a "pipeline effect".
Once the pipe effect is formed, the pilot's field of vision will become narrow.The field of vision here is not the scope of vision in a narrow sense, but the breadth of thinking and observation.Begin to subjectively ignore the unfavorable factors that affect the landing, and only want to land, and in the end it is easy to cause a security threat.
It is precisely based on this consideration that the bureau gradually withdrew the pilot's right of self-determination in the later period, and even did not give the crew the opportunity to approach under certain weather conditions.
Of course, the formulation of precipitation standards in later generations was overkill, and even Xu Cang felt that it was a bit complicated.Not only are there different restrictions on the different precipitation intensities, but even different regulations are made according to the length and level of the runway of the landing airport.In addition, there are different regulations for taking off, landing, or taking off and landing in day and night.
However, no matter how the regulations of later generations change, or whether they are strict or not, basically they cannot fall to the ground in heavy rain.Even in today's relaxed era, if the tower clearly reports heavy rain and the crew lands in the end, then the company will investigate afterwards.
"As soon as I transferred to the Hanjing district, I informed us of the latest situation. It has been steady and moderate rain before, but recently the rain has been very unstable, with moderate rain for a while and heavy showers for a while." Di Qingquan said to Bei It doesn't feel special not to make an alternate landing. Anyway, if an alternate landing is made, there is a high probability that it will be alternated to Jinmen.Jinmen is very close to Hanjing. If you really can't get up after the alternate landing, you can take a car to Hanjing by land.
Di Qingquan recalled: "What did the Hanjing District Commissioner say just now, that there are eleven planes circling in this field? Now the approach area is basically full, and there is no room for extra circling. Hanjing's It means to let us decide in advance whether to continue the approach or circle. If it is a circle, they need to guide us to the east of Jinmen in advance, only there is still airspace for waiting."
"It's all crowded to the east of Jinmen?" Xu Cang was stunned: "Is there going to be a plane coming in from behind?"
"What do you think? Hanking has more than 300 flights a day. Is it an exaggeration to squeeze more than a dozen flights now? Besides, the flights at Jinmen Airport are also very busy. If you wait a little longer, the east of Jinmen will not be able to circle around. I guess We're going to circle around the Bohai Sea." Di Qingquan said with a smile.
"What the hell?" Xu Cang himself was unwilling to make an alternate landing.Once a hub airport like Hanjing closes the airport due to weather reasons, the flights will be collectively diverted. Once the diversion is made, it is very likely that they will not be able to get up: "How is the weather in Jinmen?"
However, Di Qingquan was on the plane, so let him talk to the leader of the Air Traffic Management Bureau, maybe he can go through the back door.In the civil aviation industry, whether it is relevant or not is a completely different concept.
"Jinmen?" Di Qingquan raised his chin at the captain of the left seat: "What's the weather like in Jinmen?"
The captain quickly replied: "I read the METAR report just now, and the weather in Jinmen is very good. As for the TAF report, there is no saying that the weather will get worse."
"That means the weather is very stable." Xu Cang fell into deep thought: "The weather in Hanjing is really difficult, not to mention the precipitation, the vertical visibility is only [-], which is a bit difficult to handle. The rain can reduce the vertical visibility. It’s very rare to reach two hundred. If you really have to go around the Bohai Sea, it’s better to go directly to Jinmen.”
Generally speaking, visibility is better when it rains.But for some reason, it was written on Tongbo just now that the vertical visibility of Hanjing Airport is only [-] feet, and the decision height for blind landing is generally [-] feet. The two basically overlap, which is more difficult.
The captain turned his head and asked Xiadi Qingquan: "Master, what shall we say?"
He is indeed the captain in charge, but it is not his turn to make a decision now.
However, Di Qingquan did not answer, but turned to look at Xu Cang: "What do you say?"
"Let's go, isn't Shandong Airlines approaching in front, let's follow him, what's the point of waiting?" Xu Cang smiled and said, "It's good to have someone take the lead."
When it comes to Shandong Airlines, even the captain who has been suppressing himself will smile: "Shandong Airlines, it's normal."
"Yes!" Xu Cang also laughed, but Di Qingquan was quite helpless.
Shandong Airlines, namely Shandong Airlines, is known as the airline company's flat-headed brother, the flying iron-headed boy, the reckless man among reckless men, the one with [-]% purity, and is often ridiculed by industry personnel as the Shandong branch of Russian Airlines.
It often happens that an airport encounters some extreme weather, which leads to a large number of flight cancellations. As a result, Shandong Airlines' flights not only did not cancel, but finally landed early.
As for the reputation of Shandong Airlines, the Civil Aviation Administration of China knows a thing or two, and once reminded Shandong Airlines to rectify the style of the fleet.
As a result, Shandong Airlines agreed to it in front of it, but still went its own way when it turned back, and directly ignored the warning from the bureau.Although Shandong Airlines has a relatively "tough" style of work, there have never been any major safety problems. Even though the bureau was helpless, it did not force it too much, and finally let it go.
In fact, after more than ten years, until Xu Cang became the chief engineer of the Civil Aviation Administration, the style of Shandong Airlines has not been restrained, so that it has become a "world order me" with Aeroflot!
The marginal weather like Hanjing is quite annoying for the pilots, because although the go-around is a normal operation procedure, it contains a lot of warning items, and if there is a slight mistake, it is a lot of hard warnings.Therefore, unless there is a relatively high degree of certainty, the pilot will not conduct an approach with a high probability of going around.
In this kind of situation where you can fall or fall, there is an urgent need for a "brave" to break the deadlock.Regardless of the fact that there are eleven planes circling and waiting in the sky, as soon as the Shandong Airlines plane successfully lands, all eleven planes will have to announce their approach.
"Don't you need to wait?" the captain asked, "Let's see if the Shandong Airlines can land?"
"Wait until the Shandong Airlines lands, isn't it that our day lilies will be cold? If we wait for the Shandong Airlines to land, we will be No. 12. Let's go!" Di Qingquan made a final decision.
The chief engineer of the General Administration has said so, the captain will definitely not have any objections, and quickly reported to the Hanjing District: "National University 1344, we apply to continue the approach."
Soon, the Hanjing District Commissioner gave a reply: "National University 1344 received it, you are now at an altitude of 4000 and 030 meters, and the approach is guided by radar. Turn right and head to [-], and enter the port from the east."
The weather conditions can also be seen on the approach radar, but not as accurately as the crew's airborne radar.Normally speaking, people like Xu Cang who enter the port from the south are unlikely to enter the port from the east, because it will affect the departing aircraft.However, it seems that there are no planes leaving the field now, so there is no scruples.From the airborne radar, there is a lot of weather coverage to the west and south of the approach area.
This is just a higher and farther scan result.Generally speaking, when the altitude of the plane goes down and it gets closer, more weather will be scanned.From this point of view, the incoming planes should also enter from the east.
It’s just that Jinmen is to the east of Hanjing, and if you wait a little longer, Jinmen has reached the peak of entering the port, and the entry into the port on the east side will also be restricted.
"The altitude is 4000 and 030 meters, turn right and heading 1344, National University [-]!" the captain replied.
It is estimated that with the encouragement of Xu Cang and others, the other planes that were still hesitating in the same channel all began to ask to join the approach one after another.That's the pilot, and at some point the same herd.
When he started to turn right to join the approach, Xu Cang yawned: "Just now I saw that the wind direction has changed a lot, and the wind speed is 11 meters. It must be wind shear, right?"
The captain's face turned black all of a sudden. If windshear was encountered in marginal weather, it would not be an extremely difficult matter.
"Can you stop the crow's mouth!" Di Qingquan said speechlessly.
Pilots can be quite superstitious at certain times.
Xu Cang smiled, didn't say anything more, stretched his waist, and began to close his eyes to rest his mind again.
At this moment, in the cockpit of Shandong Airlines flight 5112, which is the first to approach, the captain Deng Wenjia is nestling in his seat leisurely, still mocking the eleven planes that were circling just now.
"So the standard for being a captain is still too low now, and they are all afraid of approaching due to marginal weather. What kind of captain is this?" Deng Wenjia sneered: "No, we have to get up Head, give them a sample."
Because it was a lead flight, the co-pilot was in control of the plane at this time, so Deng Wenjia could be so relaxed. He only had to be responsible for monitoring whether the co-pilot made any mistakes or omissions.
At this time, the plane is in the period of radar guidance, just follow the requirements of the control to lower the altitude and adjust the heading. The only thing the co-pilot has to spend brain cells is to make a deceleration plan in his mind. Deng Wenjia's chat.
"Shandong Airlines has been established for more than a year. Isn't it because of this hard work that it develops so fast?" The co-pilot said with a smile: "Other companies are all about rules and regulations, and we don't have so many requirements. We only want a safety and make money."
Deng Wenjia patted the visor: "That's the reason. What's the use of making so many rules? Isn't civil aviation just for safety and making money? What landing standards are there under precipitation conditions? This is clearly to limit the crew's subjective initiative. Let me say, Except for Shandong Airlines, everyone including the three major airlines are mediocre.”
Since the reorganization last year, Shandong Airlines has risen at an incredible speed. In this glory, being a member of Shandong Airlines naturally gives rise to some feelings of pride, and even began to underestimate the heroes of the world.
"Mr. Deng, if you put it in the past, I think what you said is quite reasonable. But now I think it is a bit biased."
Deng Wenjia is not just a pilot in Shandong Airlines, he has an administrative position, and it is not low.But the co-pilot who has no background and no power dares to refute Deng Wenjia. This is certainly related to Deng Wenjia's good temper, but it is also a good glimpse of the overall atmosphere of Shandong Airlines.
Deng Wenjia raised his eyelids: "How to say?"
The co-pilot still focused most of his energy on the aircraft instruments, and only allocated part of his energy to chatting with Deng Wenjia: "Some time ago, didn't something happen to Blue Sky Airlines in Southwest China? There was a problem with the 747 leased from Muhua Airlines. As a result, the doors of the air hatch opened."
"That!" Hearing this, Deng Wenjia slightly restrained his arrogant expression: "9811!"
"That's right, it's 9811! Mr. Deng, you should have more detailed information. It's true, as rumored, the crew flew back blindly. Is this something humans can do?" Obviously, the co-pilot was also interested in 9811. He was very interested in the incident, as if he wanted to take this opportunity to solicit gossip from Deng Wenjia: "Usually there are some safety issues, and the company has already organized a study, why is there no news at all this time?"
"You mean organizational learning?" Deng Wenjia asked.
"That's right!" The co-pilot replied: "By the way, let us understand the specific details. There is no news at all, and it's all rumors."
"Organization study?" Deng Wenjia sneered, "What do you study?"
The co-pilot was stunned: "Just to learn from the handling experience of the crew at that time!"
"We deserve him too?" Deng Wenjia sighed, "The bureau made a conclusion on the person who manipulated this matter the next day."
"So fast?" The co-pilot exclaimed, "Isn't it too fast, such a big matter can't be concluded for a month?"
Deng Wenjia smiled and said, "Let me tell you this, the person from Blue Sky Airlines is really flying blind, completely blind, he can hardly hear or see! If you can't fly under the circumstances, you said let them investigate, do they have the face to investigate?"
"It's really blind flying!" Even though he had heard the rumors before, but it was confirmed from Deng Wenjia's mouth, the co-pilot still found it incredible: "I can't see or hear, how can I fly?"
"I don't know the details. It seems that a flight attendant next to me helped me, maybe she gave some simple reminders! But you should also know that when we fly, it's like a mountain, and the flight attendants don't see each other when they go in." How much more useful than ordinary people. So, I feel that most of it depends on that person.” Deng Wenjia sighed: “You are right, if you say mediocrity, that person is definitely not. Seriously, Blue Sky Airlines’ poor settlement can produce such What a genius, it really is smoke from the ancestral grave."
The co-pilot smiled and said, "I think that person is very reckless in operating the plane, but it fits our company's temperament very well. If he can come to our company, it will be a perfect match."
"It's a pity!" Deng Wenjia curled his lips: "It seems that Blue Sky Airlines is going to die."
As he said that, the voice of Hanking’s approach came from the radio: “Shandong Airlines 5112, you can turn left and heading 230, descend to an altitude of 1000 for two hundred meters, establish a blind landing on runway 18, and report the course!”
"Turn left to heading 230, descend to an altitude of 1000 for two hundred meters, establish a blind landing on runway 18, track report." The co-pilot quickly regained his composure and repeated.
When the co-pilot adjusted the altitude and heading, Deng Wenjia sat up straight, turned his neck, and muttered: "Oh, stop talking, work!"
As the plane cut into the localizer, after notifying Hanking of the approach, the approach commanded the Shandong Airlines crew to turn to the Hanking tower.
"Hanking Tower, Shandong Airlines 5112, runway 18 is on the waterway."
"Shandong Airlines 5112, continue the blind landing approach to runway 18, complete blind landing report."
"Completely blind report, Shandong Airlines 5112!"
A full ILS means waiting until the glideslope is also intercepted.
At this time, Hanking Tower began to report the live situation to the Shandong Airlines crew, which is considered a normal operation under special weather.
"Shandong Airlines 5112, it's raining in this field, the runway is wet, the ground wind is 11 meters, the vertical visibility is 100, the RVR is 900, 1000, 1009, and the corrected sea pressure is [-]. Is it acceptable?"
The co-pilot didn't answer, but glanced at Deng Wenjia.Deng Wenjia nodded, and the co-pilot replied: "We have no problem."
"Okay!" Hanking Tower received a reply from the crew, and just said: "Shandong Airlines 5112, complete blind report."
"Completely blind report!"
After the briefing was completed, Deng Wenjia clicked his lips and looked at the co-pilot with a smile: "Are you confident?"
The co-pilot smiled wryly: "If it's only moderate rain, I think I'm fine. But the 11-meter wind is uncertain, Mr. Deng, why don't you come!"
"Although I think the co-pilot should be tempered, it is really too difficult to superimpose 11 meters of uncertain wind on the edge of the weather, so let me do it." After speaking, Deng Wenjia switched the main guide from the right to the left, and took a picture Pat the co-pilot on the shoulder: "I took your landing today, tell the planning room later, let me fly with you, I have to return the landing."
The co-pilot nodded: "Then I will remember."
After the descent track was intercepted, the FMA mode was changed to G/S, and the co-pilot notified the complete blind landing.
"Shandong Airlines 5112, this field is moderately rainy, the runway is wet, the ground wind is 11 meters, the sea pressure is corrected to 1009, the runway 18 can land, pay attention to the airflow from all sides." The control tower quickly gave the landing permission.
Correct sea pressure 1009, runway 18 can land, Shandong Airlines 5112. "
After the co-pilot finished reading back, Deng Wenjia added: "Tower, if I go around in a while, apply to deviate from the standard go-around procedure and turn right immediately."
If you follow the standard go-around procedure for runway 18, you need to keep to one side for a go-around, and turn right after the altitude reaches 400 meters.However, judging from the weather radar, there is some weather on the side of runway 18. If possible, I still hope to turn right as soon as possible.
"Shandong Airlines 5112, if you go around, you can turn right immediately."
"Okay, thank you!" Deng Wenjia thanked, and immediately began to habitually wipe his hands with a towel. This is the habit of many pilots. Before landing, wipe off the sweat on the palm of his hand, so as not to affect the feel of the lever: " Pay attention to reporting deviation data in a while, and the wipers listen to my password!"
The height is still high now, and there is no need to turn on the wipers for the time being.Generally speaking, it is not necessary to turn on the wipers before turning to the visual stage.However, there is no fixed requirement for this thing, and it is estimated that when to open it is mostly according to the meaning of the crew.
"Okay!" The co-pilot was also a high-ranking officer, and he was familiar with this kind of thing for a long time, so he quickly agreed.
Deng Wenjia adjusted the height of the seat slightly after wiping the sweat from his hands. In this marginal weather, it is better to adjust the height of the seat a little higher than usual.During the descent phase, Deng Wenjia kept the autopilot switched on. This is not because Deng Wenjia is not confident in his control ability, but because there is no need to switch to manual control too early in marginal weather. Of course, this is when the aircraft is not in good condition. subject to major changes.
This is to free up extra energy to find the runway and not miss the visual reference.
This kind of marginal weather combined with relatively obvious unstable wind is still quite difficult for many pilots, but Deng Wenjia has never seen it on any occasion, and I don’t know how many times it has flown even more difficult than this. scene?
"Altitude [-] feet, steady approach!" The co-pilot reported.
However, just as Deng Wenjia adjusted everything and put his right hand on the throttle lever, he suddenly noticed that the wind direction and wind speed display at the corner of the navigation page began to produce very bizarre changes.
Before Deng Wenjia could react, the plane suddenly lowered its head. Deng Wenjia instinctively overtook the auto throttle, turned off the throttle, and shouted: "What the hell?"
In the cockpit of China National Airlines, it is not as easy as that of Shandong Airlines in front. Di Qingquan is a serious person, Xu Cang is too lazy to speak, and the captain is afraid to speak, which makes the atmosphere in the cockpit a little bit A little stiff.
Xu Cang himself didn't like this kind of atmosphere, but this time he didn't need to fly, he just lay back, closed his eyes, and didn't care about anything.
As the aircraft cut to final and intercepted the localizer, the frequency was transferred to the Hanking Tower.As before, the Hanking tower reported the precipitation and wind direction and speed of the field, and the content was exactly the same as that reported to Shandong Airlines 5112.
After repeating the recitation, Xu Cang felt a little lucky, but fortunately, he finally stabilized in Zhongyu.If the report is a heavy shower, then there is some trouble.
Moderate rain, the vertical visibility was at the marginal value, and the wind was 11 meters, which was a relatively difficult landing condition, so that Di Qingquan asked the captain if he wanted to fly.
How could the captain dare to let Di Qingquan fly, he said quickly: "Chief Master, no need, I can handle this."
"Really sure?" Di Qingquan asked suspiciously: "Don't worry, this landing is not within the scope of supervision, so don't be nervous. If you feel unsure, just let me fly."
In fact, Di Qingquan's idea is also very simple, he just wants to land, and he doesn't want to divert.Now that the weather conditions are in line with the standard, he can't think of going around because of the technical reasons of the pilot.Now there are more than a dozen planes following them. If they go around and add other planes coming over during the approach phase, they will have to wait in the sky until the Year of the Monkey.
Captain: "Chief, I know, I have no problem with this."
"Well, that's fine!" Di Qingquan still respected the captain, since the captain said there was no problem, he still chose to believe it.He has inspected many captains of National Airlines, and the overall impression is good: "Okay, then you fly. Remember, don't pursue lightness, come to a solid landing."
Di Qingquan was worried that in order to impress him, the captain purposely landed lightly, which violated the principle of landing on a wet runway, and would cause trouble if the plane skidded.
"I know, I know!" The captain was still struggling with this matter just now.Of course he knew that when there was a lot of rain, he had to land firmly, but he was worried that it would make Di Qingquan mistakenly think that it was a heavy landing, so he had a bad association with himself.
Now that Di Qingquan spoke up by himself, there was no need to worry.
Di Qingquan's message to relieve the captain's mental burden is still somewhat useful, at least Xu Cang's body is not so tense behind him, otherwise Xu Cang would feel very uncomfortable just looking at the captain's sitting posture.
Xu Cang is not worried about this landing. A person who can be a captain should be a bit real, and looking at the assignment book hanging, this captain is not just a single-pilot captain, but an instructor. The experience is also relatively sophisticated and can be trusted.
He yawned, and seeing that he was about to hit the ground, he sat up a little bit and pulled himself together.Although it has nothing to do with me, it seems impolite to still sleep after landing.
However, I was really lucky today. Precipitation, vertical visibility, and wind direction and speed are all critical, and if any one exceeds the standard, I will not be able to fall.
At this moment, the control tower reminded again: "National University 1344, the front aircraft reported that the airflow changes sharply below the altitude of [-] feet, please pay special attention."
The captain was stunned: "Has the windshear warning been triggered? Is the plane in front of it a Shandong Airlines plane? Has it landed?"
"The crew did not report that the windshear was triggered, and now the Shandong Airlines plane has landed normally."
"That's fine, let's continue approaching, thank you!"
Windshear falls under the category of mandatory reporting, and as long as it is triggered, the crew should report it to the control.Since there was no report from Shandong Airlines, it seems that no wind shear was encountered.
The only thing the captain is more worried about is wind shear, if it is just unstable airflow, it is quite acceptable.
"If it's below 800 feet, doesn't that mean we've arrived?" The captain looked at the altimeter, and now there are only more than [-] feet left above the ground.However, from the perspective of perception, there is some shaking of the plane, but the magnitude is not very large.
Even Di Qingquan, who was on the side, said with a relaxed expression: "It seems that we are lucky, and that part of the turbulence drifted away?"
The captain was still on autopilot at this time, and he was more concerned about looking for visual references. The stability of his body made him feel that the airflow on the final side should not be as strong as the previous aircraft reported.
However, Xu Cang's expression in the back gradually became serious, because he clearly saw the wind direction at the corner of the aircraft's navigation ND changing at an extremely fast speed.
Originally, the plane was facing the headwind, but in less than two seconds, the wind seemed to circle, and the wind direction quickly switched from headwind to tailwind.
Xu Cang's expression changed, and just as he was about to remind the captain, the airspeed kept dropping like a deflated ball.The captain didn't notice the change in wind direction, but he saw the change in airspeed, and his first thought was to intervene in the autothrottle to make up some thrust.
Because Boeing's autothrottle response is relatively slow, human intervention is often required in order to maintain speed accuracy in turbulent conditions.
At this time, the captain still believed that the aircraft was only a matter of speed.But after he pushed the accelerator up, the speed of the plane did not stop.He was stunned for a moment, and then added a little bit of accelerator, but what greeted him was "windshear" warnings!
"Wind Shear!"
The captain yelled, and almost reflexively executed the windshear recovery maneuver.Accelerate, press TO/GA, disconnect the autothrottle, use maximum thrust, start at [-] degrees, and follow the flight guidance.
However, he didn't miss the previous actions such as increasing the gas pedal to the maximum, but at the moment when he started to lift, the plane's already low speed suddenly slowed down, and the speed fell directly into the red zone, and the steering wheel began to move crazily. Shaking up, everyone's ears were filled with the warning sound of shaking the stick.
The moment the plane shook the stick, Di Qingquan's expression tightened, and he was ready to intervene.At such a low altitude, if the plane stalls, wouldn't it all be over.
Like Di Qingquan, the captain's reaction was also the same, he was going to put a little pressure on the game first.
However, the moment the captain wanted to push the rod, a hand stuck out from behind, firmly restraining the captain's movement.The captain was startled, turned his head to look, but saw Xu Cang's gloomy face, and asked back: "What do you want to do?"
PS——The latter part is in the author's words below.
The captain's complexion changed, and he suddenly exclaimed: "Xu Cang?"
However, Xu Cang didn't pay any attention to it, and ignored the captain at all. At this critical moment, Xu Cang didn't push the shot, instead, he took the down shot slightly.
However, this action directly made the captain's hairs stand on end, and he clasped Xu Cang's wrist with his right hand, and shouted: "The plane has stalled, are you still carrying the stick?"
Xu Cang said coldly: "Do you really know how to fly a plane? Now at such a low altitude, if you dare to push the pole, put your aim above the pitch limit indicator. Can you do it? If you can't, then let I'm going to fly!"
