When Xu Cang and Bi Lin appeared at the door of the lounge, Di Qingquan and Chen Guoli, who were waiting outside, immediately came forward.

"General Commander Di, when can I go to Qitai?" Xu Cang asked first.

"Did you decide to go?" Di Qingquan's eyes lit up and he immediately said: "There is no commercial route between Shule and Qitai, so it is naturally possible at any time. I will report the time you want and will be approved soon. However, the only thing to note is to communicate with Qitai Airport in advance. Although Qitai is extremely snowy and the ice protection work is not effective, it is better than nothing. You have to notify Qitai Airport in advance so that they can prepare for the landing time."

"That's how it's convenient." Xu Cang thought for a while: "Why go now?"

Bi Lin waved his hand and stopped him, "You don't have to be so anxious. Although Qitai Airport is not considered a high plateau, the altitude of nearly 8,000 feet is still a bit burden on your body. Xu Cang, you are tired today, and you may be tired. You should take a day off and take a good rest. Let's go tomorrow. Moreover, let's communicate with Guoli in advance tonight so as not to make any mistakes in cooperation tomorrow."

These words made Chen Guoli, who was uneasy, overjoyed: "Can I still go?"

"Why can't it?" Bi Lin asked back: "However, tomorrow's verification flight is mainly Xu Cang, so you can assist the national strength from the side. Moreover, if you encounter special circumstances, listen to Xu Cang firmly and understand?"

"I understand, understand!" Everyone was ready to be kicked out of the verification crew. Unexpectedly, Bi Lin agreed to let him continue to participate. Chen Guoli was already content and nodded quickly: "I must focus on Xu Cang!"

Bi Lin is quite trusting about Chen Guoli's guarantee. At least his words are definitely very useful for Chen Guoli.

"When will you set out tomorrow?" Xu Cang asked suddenly.

"It's afternoon. The visibility in Qitai is often not good in the morning. The sun rises for a while before the fog is dissipated. So in the afternoon. Moreover, there are probably a few more guests."

"Guest?" Xu Cang was puzzled for a moment: "Is anyone here to observe?"

Bi Lin smiled: "That's right."

After saying that, Bi Lin patted Di Qingquan: "Arrang to take them to rest."

"Yeah, no problem." Di Qingquan responded quickly.

Xu Cang looked around and when he came to the airport just now, he found a hotel near the airport. He didn't know if he was staying there. However, as he thought about it, a little burning sensation appeared in his stomach, and he suddenly felt a little hungry.

When I came here, I drank some water, but I didn't eat much of the stuff that filled my stomach. I decided not to move today, and I felt hungry if my nerves relaxed a little.

"Chief Master Di, the car has to wait for a while, right?" Xu Cang asked.

Di Qingquan, who had just put down his cell phone, nodded: "I've called it, it's probably more than ten minutes. It's a temporary arrangement, so I have to wait."

"More than ten minutes?" Xu Cang looked into the lounge, saw a table with snacks placed inside through the glass door, and said to Bi Lin: "Dean, will I go inside?"

"Hungry?" Bi Lin noticed Xu Cang's gaze just now, and immediately guessed Xu Cang's thoughts: "Go, eat less snacks and make a stomachache. When you arrive at the hotel, let the hotel arrange food."

Xu Cang nodded: "Yeah, remember."

With Bi Lin, Xu Cang didn't look very reserved. With Bi Lin's permission, he hurried back to the lounge.

Just after Xu Cang returned, Bi Lin suddenly heard a sound of gurgling beside him. He turned his head and saw that he was facing Chen Guoli, whose face was flushed.

"I am not hungry." Chen Guoli stammered.

Bi Lin had no choice but to wave his hand: "You go and take a cushion too. You are old, don't get hungry."

Chen Guoli looked back and saw that Xu Cang was already having a feast in the lounge, and he couldn't help it: "Then I'll go and cushion?"

"Go!"

Now Chen Guoli no longer hesitated and went back to join the ranks of dry rice.

"Since Teacher Chen came back from Qitai, he has not eaten anything, so he was afraid he was hungry." Di Qingquan turned around and looked at the two of them: "Now Teacher Chen is willing to eat, so he is afraid he is not as heavy as before."

Bi Lin narrowed his eyes: "Most of the pressure has now reached Xu Cang. If the pressure is gone, I will feel relaxed."

Looking at Bi Lin's side face, which was a little ignorant, Di Qingquan licked his lips, hesitated for a while, and asked softly: "Old Bi, I don't know if I should ask or not?"

"What nonsense is it? Ask if you ask, don't ask, don't ask, and I'll decide for you?" Bi Lin looked at Di Qingquan with his eyes squinted, and finally did not scold Di Qingquan again: "Tell me."

Di Qingquan Ru received an amnesty and coughed, lowering her voice: "Old Bi, to be honest, I really don't understand that the single-sending program at Qitai Airport needs to be so risky to verify it? After all, this matter actually has little to do with our civil aviation."

"Qingquan, at the mobilization meeting a few days ago, the technician from the design institute said that the procedures for military transport aircraft have been verified."

The technician of the design institute mentioned by Bi Lin was the middle-aged man who sat with them at the meeting not long ago. Di Qingquan also remembered what Bi Lin said. A teacher asked, because the teacher heard that the single-send program at Qitai Airport had been verified, and he didn't know why he had to verify it again.

The technician's answer was that given the differences in climbing performance of military transport aircraft and civilian passenger aircraft, the procedures of the two are different and need to be verified separately. The verification is the procedures of military transport aircraft.

"Yes, I remember saying this." Di Qingquan glanced at Bi Lin's expression. He felt a little bad premonition: "Old Bi, is there any problem?"

Bi Lin sighed: "In fact, the verification effect of the transport aircraft is not good. If there is a situation, it is almost certain that civilian transportation capacity must be used, which is almost inevitable. Xu Cang is right. He has done Yulong once, and Qitai should not be looking for him this time. However, a single-shot verification must be a person who really flies once. It is best if there is no problem. If there is a problem, you can also know the problem more clearly, at least it is faster and more effective than solving it on the drawings."

"Old Bi, now everyone is developing, there won't be that situation, right?"

Bi Lin suddenly turned his head and looked at Di Qingquan: "It is because of its development that it needs protection, right?"

"The location of Qitai is so important, so you must maintain sufficient transportation capacity for this place. You just need to trouble Xu Cang." Bi Lin was halfway through his speech, and suddenly felt something. He turned around and found that Xu Cang had actually arrived at the glass door of the lounge. Bi Lin immediately changed his expression and smiled, "How many bites did you eat?"

Xu Cang looked satisfied and pushed open the glass door: "The dried fruits here are so delicious, and it turns out that the fruits in our northwest are awesome."

"Let's go back to Qitai, and I'll give you enough fruits for a plane to eat." Bi Lin said with a smile.

"I don't have to resell the fruits of an airplane, don't you mind?"

Bi Lin smiled and said, "Of course it's what you want."

While speaking, a minibus came from a distance, and there was a sign from Shule Airport on the body. It should be the car to pick up people, which was much earlier than expected.

"Is this one?" Bi Lin asked.

Di Qingquan stretched his neck and looked at it a few times: "It should be, Mr. Bi."

After saying that, Di Qingquan shouted into the lounge: "Teacher Chen, the car is here and I'm leaving!"

Soon, the car was in place. Bi Lin and Chen Guoli got on the car one after another, and Xu Cang was the third one. However, just as Xu Cang wanted to get on the car, Di Qingquan, who was following behind, suddenly said: "Xu Cang, you just now."

Xu Cang turned around and looked at Di Qingquan with some confusion: "What's wrong?"

Seeing Xu Cang's somewhat confused expression, Di Qingquan's expression froze and then smiled and said, "It's okay, get in the car."

Shule's airport hotel is built next to the nearby lake. You can see the rippling lake surface reflected by the moonlight when you leave the hotel gate. On a hillside on the lake, Xu Cang sat on a stone, looking at the jade plate undulating with the water in the middle of the lake, dazed and dazed.

Suddenly, a figure appeared behind Xu Cang, but it was teacher Chen Guoli.

"The wind is strong and cold at night in Shule, are you just blowing like this?" Chen Guoli said with a smile, looking for a big stone next to Xu Cang to sit down.

Xu Cang's thoughts were interrupted by Chen Guoli, and he also smiled and said, "Young man is angry, so it's okay to take advantage of the situation. However, Teacher Chen, you have to pay attention."

Chen Guoli patted the thick down jacket on his body: "It's very well equipped."

After saying that, Chen Guoli's smile on his face was much more restrained and asked a little solemnly: "Are you thinking about tomorrow's test flight?"

"That's all right." Xu Cang turned his head: "What else does Teacher Chen need to say?"

"Well, technically, I don't have any qualifications to ask for anything. However, I did not say something during the day." Chen Guoli said with concern: "In addition to studying the single-shot program, I also studied the meteorological and geographical data around Qitai Airport."

Xu Cang's mouth raised a trace of arc: "Teacher Chen, you know astronomy and geography."

"Oh, talent is not top-notch, so I can only work hard." Chen Guoli smiled self-deprecatingly: "However, I have really developed some things. I won't talk about the beginning obstacles. Even if the remaining obstacles retained in the program are very small, no matter what, it is in line with the regulations. What I want to say is another thing."

Xu Cang became a little interested: "What's wrong?"

"When I flew to Qitai during the day, I found that although Qitai Airport was windy and snowy, the temperature was low, and the surroundings were very deserted, there was a lot of vegetation at the bottom of the valley below Qitai Airport." Chen Guoli said.

The location of Qitai Airport is very special. It is at the turn of a U-shaped canyon. Therefore, the five sides approaching Runway 28 enter along one end of the U-shaped canyon. In the final descent stage, the plane almost penetrates the canyon, and the mountains on both sides are higher than the plane.

Therefore, at a low point, if you look at the GPWS display, the plane is almost moving in a red zone. If you deviate slightly from the five-sided track, the terrain warning may sound.

When approaching on the five sides, you enter from one end of the canyon. If you return to flight, you must first maintain the course, reach the field with a height of more than 4,500 feet, and then turn right and go out along the other end of the canyon.

In a sense, the go-around program and the single-engine program overlap at the initial stage. However, when the double-engine is normal, the aircraft's climbing performance is excellent. Although the trajectory coincides with the other end of the canyon, in fact, the aircraft can quickly break away from the canyon terrain.

However, in the case of a single-engine, the climbing performance of the aircraft is severely restricted. Therefore, after the take-off and climbing stage is over, you will have to plunge into the canyon.

There is no way. The main vein of Tianshan Mountain is far away from the runway No. 28. It is like a natural barrier for a single-engine aircraft, and it is impossible to cross it.

In fact, in a single-shot program, if you can not turn, it is best not to turn, and climb up straight up straight is the best. Because once the plane turns, the lift will be decomposed, and the already poor rise rate will be reduced by a few points.

When encountering some extreme situations, the plane may not even be able to maintain the positive rise rate once it turns, which is untolerable in a single-shot procedure.

However, the main vein of Tianshan is in front and you have to change the horizontal trajectory without changing it. After passing through one side obstacle, follow the single-shot procedure, the plane must turn right at an extremely large angle of more than 120 degrees.

During this turn, it is almost impossible for the plane to keep rising.

However, according to the description of the single-stroke procedure, there is no threatening terrain below the turning position, so as long as the aircraft can maintain a level flight, there is no danger. What is more troublesome is the problem after the turning.

After the plane turns and level the plane will enter the canyon. Moreover, given the poor climbing performance in a single-shot situation, the flight in the middle of the canyon will be maintained for a period of time. However, the program shows that at this stage, as long as the plane maintains a climbing gradient of 1.2%, there will be no terrain danger even in the canyon.

Under a smooth state, under normal circumstances, a 1.2% climbing gradient is absolutely guaranteed, but Chen Guoli discovered another problem, a possibility that the aircraft could not maintain even a 1.2% climbing gradient.

Xu Cang was not as knowledgeable as Chen Guoli, and even studied meteorological and geographical data. After Chen Guoli said this, Xu Cang obviously didn't understand it very well.

"Teacher Chen, I'm angry that I'm superficial in knowledge. I don't quite understand what you mean." Xu Cang was seeking truth from facts. If he didn't understand, he wouldn't understand.

Chen Guoli thought for a little while and suddenly pointed to the main vein of Tianshan Mountain in the distance, which was crawling like an ancient giant beast: "Northern winds are mostly prevalent in this season. However, at this time this year, there is still a strong monsoon coming from the southwest, but it was eventually blocked by the Tianshan Mountains."

Xu Cang was stunned and a little geographic information quickly emerged in his mind. Indeed, in winter, due to the existence of high pressure in Mongolia, there should be more north winds, and south winds are indeed rare at this time.

Chen Guoli continued: "The southwest wind is very strong, and even the Tianshan Mountains cannot stop it. They will cross the entire mountain range and then hit down the slope, such as there."

As he said that, Chen Guoli pointed in another direction, which was pitch black and there were only some heavy shadows, and Xu Cang could not see anything. However, Xu Cang knew what that direction meant.

If nothing unexpected happens, it will be the departure side of the single-shot runway of Qitai Airport tomorrow.

"Downward rushing" Xu Cang chewed slightly, and asked in an uncertain tone: "Are you talking about Burning Feng?"
