Chapter 126 Wind shear! Let me fly! (Please subscribe!)

"Where is Tongbo?" Xu Cang reached out and hooked at Di Qingquan.

The captain in the left seat was stunned when he saw Xu Cang's movement. Xu Cang looked young, so why was he as big or small as Di Qingquan? However, Di Qingquan didn't think there was any problem, so he gave Xu Cang the paper Tongbo clipped on the wheel.

The printers on the 737 in this era are far less compact and convenient than those on the later models. The width of the paper strips is more than twice that of the printers in later generations. Moreover, the paper texture of the paper strips is soft and easy to break, and they will be torn if you are not careful. After about seven or eight years, the printers on the 737 will be reformed on a large scale, and even the printer paper will be upgraded.

After taking the paper Tongbo handed over by Di Qingquan, Xu Cang looked at it for a while and threw it on the central console: "The Tongbo talks about moderate rain, why do you say that it is going to be a big shower?"

In this era, people are not very concerned about the landing standards under precipitation conditions. They don’t care about light rain, moderate rain, etc., just see if they can see the runway in the end.

But generally speaking, moderate rain is acceptable under daytime conditions, and at night, moderate rain is more likely to affect the final visual reference. However, whether it is day or night, if heavy rain reaches a certain point, it is more difficult to deal with. Rain water can directly form a layer of unwieldy water covering on the windshield. Even if the wiper is opened to a high level, the scraped rain water will be quickly filled by the rain water behind, resulting in a reduction in visual ability.

However, in various degrees of precipitation, showers are quite special. The recognition of showers has always been very vague. Should they be determined according to the highest level of the reported showers, or do they need not be considered, and they are entirely based on the visual judgment of the crew?

For example, for heavy showers, some people think that it should be directly considered as heavy rain, or whether heavy showers are not suitable for unified precipitation standards depends on whether the unit can obtain visual reference at the determination height and continuously obtain appropriate visual inspection at the following heights.

Maybe some people think that it is not good to set standards and finally judge only by the crew’s visual judgment? Needless to say, the weather of variable showers is like, even if it is stable precipitation, such as moderate rain.

The distribution of rainwater is not uniform. It may be that precipitation is relatively dense in some areas and is slightly weaker in some areas. In weak areas, it actually has no effect on landing.

In this way, why do we need to impose rigid restrictions on landing? It is precisely based on this concept that even if many airlines have landing regulations under precipitation conditions, the actual flight implementation is not strictly implemented.

The main reason is that the pilot's excessive autonomy can easily lead to some possibility of forcibly landing, which will undoubtedly increase hidden dangers. Pilots are also humans, and no pilot is willing to prepare for landing. This often leads to the pilot's subjective idea of ​​landing when encountering marginal weather, that is, the so-called preset position, so that the pilot has a "pipeline effect".

Once a pipeline effect is formed, the pilot's field of vision will become narrow. The field of vision here is not the narrow range of vision, but the breadth of thinking and observation. The disadvantages that affect landing are subjectively ignored, and only want to landing, it will easily cause safety threats in the end.

It is precisely based on this consideration that the bureau gradually revoked the pilot's right to self-determination in the later period, and even did not give the crew the opportunity to approach under certain meteorological conditions.

Of course, the precipitation standards in later generations were overestimated, and Xu Cang felt that it was a bit complicated. Not only did there be different restrictions on the intensity of precipitation, but different regulations were even made based on the length and level of the runway at the landing airport. In addition, there are different regulations on day and night, whether to take off, whether to land, or take off and landing.

However, no matter how the regulations in later generations change, or whether they are strict or not, they will basically not be able to land when they encounter heavy rain. Even in today's loose era, if the tower clearly reports heavy rain and the unit finally lands, it will be investigated by the company later.

"I just transferred to Hanjing District to inform us of the latest situation. It has been stable moderate rain before. Recently, the rain has been very unstable. Sometimes it has moderate rain and sometimes it has heavy rain." Di Qingquan didn't have any special feeling about whether to prepare for a landing. Anyway, if it is prepared for a landing, it is likely to be reserved for a landing. Tianjin is very close to Hanjing. If it is really not ready for a landing, it is impossible to get up after a landing, at most it can take a car to Hanjing by land.

Di Qingquan recalled: "What did the Hanjing District Transfer just now? There were eleven planes hovering in this field? Now the approaching area is basically full, and there is no extra space to hover. Hanjing means to let us decide whether to continue approaching or hovering. If it is hovering, they need to guide us to the east of Tianjin in advance, and there is only airspace for waiting there."

"Are you all squeezed to the east of Tianjin?" Xu Cang was stunned: "Is there a plane coming in behind?"

"What do you think? Hanjing has more than 300 flights a day, but now it's very exaggerated to squeeze in more than a dozen flights? Besides, the flights at Tianjin Airport are also very busy. If you wait for a while, you will have to circle the east side of Tianjin. You probably have to go around the Bohai Sea." Di Qingquan said with a smile.

"What's the matter?" Xu Cang himself was unwilling to prepare for landing. Once a hub airport like Hanjing closed the airport in response to weather reasons, it is likely that he would not be able to get up once it was ready for landing: "What's the weather in Tianjin?"

However, Di Qingquan was on the plane, so he asked him to talk to the leaders of the Air Control Bureau that he could not walk around the back door. In the civil aviation industry, whether it is related or not, that is a completely different concept.

"Tianmen?" Di Qingquan raised his chin at the left-handed captain: "What do you say about the weather in Tianjin?"

The captain quickly replied: "I just read the METAR newspaper. The weather in Tianjin is very good. As for the TAF newspaper, there is no saying that the weather will become worse for the time being."

"That's the weather is very stable." Xu Cang fell into deep thought: "The weather in Hanjing is really difficult to deal with. I won't talk about precipitation for now. The vertical visibility is only 200, which is a bit difficult to deal with. It is rare to see the vertical visibility drop to 200 when it rains. If you really want to turn around the Bohai Sea, it would be better to just prepare to go to Tianjin."

Generally speaking, the visibility is better when it rains. But for some reason, just now, the vertical visibility of Hanjing Airport is only 200, while the decision height for blind landing is generally 200 feet. The two basically overlap, which is more difficult to deal with.

The captain turned around and asked Di Qingquan: "Chief, what do we say?"

He is indeed the captain of responsibility, but now it is not his turn to make the decision.

However, Di Qingquan did not answer, but turned around and looked at Xu Cang: "What did you say?"

"Let's go, isn't Shanhang's approaching ahead? Let's follow him. What's the point of waiting?" Xu Cang smiled and said, "It's better to have someone to take the lead."

Speaking of Shanhang, even the captain who had been suppressing would smile: "Shanhang is normal."

"Yes!" Xu Cang also laughed, but Di Qingquan was quite helpless.

Shanhang, namely Shandong Airlines, is known as the airline flat-headed brother, the flying iron-headed man, the reckless man among the reckless man, and the kind of 100% purity is often teased by industry insiders as the Shandong branch of Russian Airlines.

It is often seen that certain airports encounter certain extreme weather, resulting in large-scale cancellation of flights. As a result, Shandong Airlines' flights are not only not cancelled, but can finally land in advance.

The Civil Aviation Administration of China naturally knows the reputation of Shanhang. It has also reminded Shanhang to rectify its fleet style and not to be reckless all day long or brainless.

As a result, Shanhang agreed in front of him, and he still did his own thing, directly treating the bureau’s reminder as a warning. Although Shanhang’s style is relatively "hard", there has never been any major safety problems. Even though the bureau is helpless, it has not forced him too much, and finally let it go.

In fact, after more than ten years, until Xu Cang became the chief officer of the Civil Aviation Administration, Shanhang's style has not been restrained, so he became the "me of the world" with Russian Airlines!

Fringe weather like Hanjing is still quite annoying for pilots, because although going back to fly is a normal operation process, it contains a lot of warning items. If it is a little wrong, it is a lot of hard warnings. Therefore, unless you are more sure, the pilot will not make a high probability of going back to fly.

In this situation where you can or cannot fall, a "brave" is urgently needed to break the deadlock. Although there are eleven planes hovering in the sky and waiting, as long as the Shanhang plane lands successfully, all eleven planes will have to announce their approach.

"Don't you have to wait?" asked the captain: "Let's see if that mountain airline can land?"

"We are still waiting for Shanhang to land, but we are not going to be cold even if we are going to land? If Shanhang land, we are not the second one, the twelfth one, let's go!" Di Qingquan made the final decision.

The chief officer of the General Administration said this, and the captain would definitely not have any objection. He quickly reported to Hanjing District: "National University 1344, we apply to continue approaching."

Soon, the Hanjing District Transfer responded: "National University 1344 has been received. You are now down to a height of 4,200 meters. The radar guides the approach. Turn right to head to 030 and enter the port from the east."

The weather conditions can also be seen on the approaching radar, but it is not as accurate as the airborne radar of the crew. Normally, those who enter the south like Xu Cang will not enter the port from the east because it will affect the departure planes. However, there seems to be no departure planes now, so there is no scruples. From the airborne radar, there is a lot of weather coverage to the west and south of the approaching area.

This is just a scan result that is higher or higher. Generally speaking, when the aircraft reaches altitude and get closer, more weather will be scanned. If you see this, the subsequent aircraft that comes in should also enter from the east.

However, Tianjin is on the east side of Hanjing. If you wait a little longer, Tianjin will reach the peak of entry into the port, so the entry into the port on the east side will be restricted. It is better to approach as soon as possible. There is no future if you wait hard.

"The lower altitude is 4,200 meters, turn right and head to 030, National University of China 1344!" the captain replied.

It is probably inspired by Xu Cang and the others, all other planes on the same channel that were hesitating began to ask for an approach. This is the pilot, who was the same as the shelter at some point.

When he started turning right and joined the approach, Xu Cang yawned: "I saw that the wind direction changed a lot just now. The wind speed was eleven meters. Isn't it necessary to change the wind shear?"

The captain's face suddenly turned dark. If he still encountered wind shear in the marginal weather, it would not be an extremely difficult thing.

"Can you please not have the crow's mouth?" Di Qingquan said speechlessly.

At some point, pilots are quite superstitious.

Xu Cang smiled, said nothing more, stretched, and began to close his eyes and rest.

At this moment, in the cockpit of the first approaching Shanhang Flight 5112, captain Deng Wenjia was lying leisurely in his seat, and was constantly mocking the eleven planes that had just been hovering.

"So the standard for captains is still too low now. They don't dare to approach the edge of the weather. Why are they the captains?" Deng Wenjia sneered: "Now, we have to make a good start and give them a good example."

Since it was taken to fly, the plane was operated by the co-pilot at this time, so Deng Wenjia was so easy. He only needed to monitor whether the co-pilot had any mistakes or not.

At this time, the aircraft is in the radar guidance period, as long as the height and course are adjusted according to the requirements of the control, the only thing that the co-pilot has to consume is to make a slowdown plan in mind, and there is basically no need to think about the rest, so that he still has the leisure to deal with the chat with Deng Wenjia.

"Our Shanhang has been established for more than a year. Didn't it be because of this ruthlessness that it has developed so quickly?" The co-pilot said with a smile: "Other companies are all rules and regulations, so we don't have so many requirements, just seeking safety and making money."

Deng Wenjia patted the blindfold: "That's the reason. What's the use of setting so many rules? Isn't civil aviation just for safety and money making? What are the landing standards under precipitation conditions? This clearly limits the crew's subjective initiative. If I want to say, except for our Shanhang Airlines, all of them are mediocre people, including the three major airlines."

Since its reorganization last year, Shanhang has risen at an incredible speed. In this glory, as a Shanhanger, he naturally has some pride and even began to underestimate the heroes of the world.

"Mr. Deng, if it were in the past, I think what you said makes sense. But now I think it's a bit biased."

Deng Wenjia is not just a pilot in Shanhang, he has an administrative position, and it is not low. However, 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 can also see that the overall atmosphere of Shanhang is good.

Deng Wenjia raised his eyelids: "What do you say?"

The co-pilot still focused most of the energy on the aircraft instrument, and only divided part of the energy to chat with Deng Wenjia: "Some time ago, did something happen to Blue Sky Airlines in the southwest? There was a problem with the 747 leased from Muhua Airlines, and the air cabin doors were all opened."

"That!" Hearing this, Deng Wenjia slightly restrained her arrogant expression: "9811!"

"Yes, it's 9811! Mr. Deng, you should have more detailed information. It's really like the rumors that the crew flew back blindly. This is something that people can do?" Obviously, the co-pilot was also quite interested in the 9811 incident, as if he took this opportunity to gossip from Deng Wenjia: "There are some safety issues in normal times, and the company has organized learning for a long time. Why is there no news this time?"

"You mean organizing learning?" Deng Wenjia asked.

"Yes!" the co-pilot responded: "By the way, let us understand the specific details. There is no news now, and it is full of rumors."

"Organize learning?" Deng Wenjia sneered: "What to learn?"

The co-pilot was stunned: "Just learn the crew's handling experience at that time!"

"We are worthy of him too?" Deng Wenjia sighed: "The bureau concluded the next day about this."

"So fast?" exclaimed: "This is too fast. Such a big thing cannot be delayed for a month before the conclusion is drawn?"

Deng Wenjia smiled and said, "I'll tell you this. The person from Blue Sky Airlines is really flying blindly, completely blindly, almost inaudible or invisible! After the people from the bureau learned about the situation in advance, they felt that they could not fly under the same circumstances. Do you want them to investigate? Do they have the attitude to investigate?"

"It's really a blind fly!" Even though he had heard the rumors before, it was confirmed from Deng Wenjia that the co-pilot still felt incredible: "I can't see or hear, how can I fly?"

"I don't know the specific details. It seems that a flight attendant next to him helped, maybe he gave some simple tips! But you should also know that when we fly, it's like a mountain, and the flight attendant is not necessarily much more useful than ordinary people when entering. So, I feel that most of it depends on that person." Deng Wenjia sighed: "You are right. If you want to be mediocre, that person is definitely not. To be honest, the dilapidated Blue Sky Airlines can produce such a genius, it is really a smoke from the ancestral grave."

The co-pilot followed and said, "I think that man is very reckless in controlling the plane, but it is very consistent with our company's temperament. If you can come to our company, it will be a perfect match."

"What a pity!" Deng Wenjia curled her lips: "It seems that it will be rotten in the blue sky aviation."

As he said that, the voice of Hanjing approaching came from the radio: "Shanhang 5112, you can turn left and head 230, with a height of 1,200 meters. Establish runway 18 and blind landing, and report the waterway!"

"Turn left to head 230, with a height of 1,200 meters. Establish runway 18 and blindly land. Report the waterway." The co-pilot quickly calmed down and recited again.

While the co-pilot was adjusting the height and course, Deng Wenjia sat upright, turned her neck, and muttered: "Oh, I won't talk anymore, I'll work!"

As the plane cut into the course, after informing Hanjing to approach, the approach commanded the Shanhang crew to transfer to the Hanjing Tower.

"Hanjing Tower, Shanhang Runway 5112, 18 is already the route."

"Shanhang 5112, continue to move forward blindly on the runway 18, and report completely blindly."

"Reported completely blind landing, Shanhang 5112!"

The meaning of completely blind landing is to wait until the downhill is intercepted.

At this time, the Hanjing Tower began to inform the Shanhang crew of the live scene, which was a normal operation in special weather.

"Shanhang 5112, now this time is moderately rainy, wet runway, ground wind is uncertain and windy eleven meters, vertical visibility is 200, RVR is 100,900,1000, respectively, and sea pressure is 1009. Can it be accepted?"
