Say a sonnet on VHF

The frequency band of Very High Frequency (VHF) ranges from 30MHz to 300MHz, and the propagation mode is generally direct wave, which is less affected by terrain and weather interference. It is not only used in air and land communication frequency bands, but also VHF omnidirectional beacons. Taiwan (VHFOmni-directionalRange, VOR). VOR is a very important navigation facility, but with the development of navigation technology, ground-based navigation stations like VOR will gradually be replaced by satellite-based regional navigation systems.

The operating rules of regional navigation (RN□□) are very different from traditional navigation. Relying on Beidou, it has been implemented throughout the central and southern regions in the past two years.For Cheng Yang and the others, the most intuitive feeling is that there has been more training.

The traffic has increased, and there are more classes on duty, and as a result, more and more classes are taken.

It was May [-]st soon, and the Bureau started a meeting again. After the meeting, Cheng Yang was a little sleepy, so he was about to go to the lounge to sleep for a while, but was stopped by Director Xing of the control department.

Director Xing focuses on new technologies. Normally, he does not meet people. He always holds meetings in various places, or follows up the projects of the Central South Bureau and the University of Aeronautics and Astronautics in Nanjing.Cheng Yang followed him into the office, knowing in his heart that he might be sent on a business trip.

To be honest, their band has a small show this weekend, so he doesn't really want to go.

Director Xing looked at him with a smile, and asked him to sit down and cut straight to the point.

"I'm going to Europe in June and want to take you with me."

Cheng Yang was a little surprised: "Europe? Go to Europe Control for a meeting?"

Director Xing sighed: "The ICAO Beijing office wants to organize us to go to Oukong to learn about the use of European regional navigation. ICAO proposed it, and of course we have to cooperate. In fact, I don't have many choices for candidates. I can take you. , or take Yumeng with you. But the Ministry of Control originally discussed sending Yumeng to study in Sweden for a year next year, so I want to leave this opportunity to you."

Xing Chao paused, and added: "What's your intention?"

Cheng Yang didn't even hesitate.

"go."

"Okay. Then I will tell the HR side to transfer shifts. You may have to work hard this month."

Cheng Yang smiled: "No problem. Thank you Director Xing."

Xing Chaoren was very kind, and smiled at Cheng Yang after hearing this sentence: "Just go out to play and get in touch."

Cheng Yang nodded, and didn't say anything else about this issue.

"How is our RN□□ program doing?"

"The Academy of Aeronautical Sciences is working on a navigation database, and it will be available in the second half of the year." Xing Chao has been watching this matter, so he is very familiar with it. "Recently, you have been training, so get ready."

"Should be."

Seeing that he had finished what he had to say, Cheng Yang stood up.

"Director Xing, if there's nothing else, I'll go to the lounge first."

Xing Chao nodded, and Cheng Yang opened the door and came out. After he came out, he didn't go to the lounge, but checked his phone.

Wechat plus SMS, he sent about fifteen or six messages to Chu Shiqing in the past two days, but Chu Shiqing didn't reply a single one.Cheng Yang frowned. He knew that Chu Shiqing should be attending classes in Guangzhou, and theoretically there would be no obstacle to answering the message, so Cheng Yang was a little worried.

He swiped his card to go out, and called Chu Shiqing in a stairwell next to him.

Chu Shiqing received it unexpectedly quickly.

"Cheng Yang."

These two words on the other end of the phone made Cheng Yang feel a little uncomfortable.He is very familiar with Chu Shiqing's tone. When the two of them had conflicts in Bodao earlier, Chu Shiqing sometimes spoke like this.It expresses one meaning: what the hell is going on.

"I'm fine." Cheng Yang subconsciously resisted, "I didn't reply to your WeChat or text messages, so I called and asked."

Chu Shiqing sounded a little confused.

"Oh, I saw your message." Chu Shiqing's tone was very light. "My sister has a lot of classes recently. I will ask her to come back next week. Let's have a meal. Then if you have time, chat with her and have an afternoon drink." Tea."

Cheng Yang frowned tightly, and took two steps left and right.

"Are you OK?"

These words stopped Chu Shiqing immediately.What he wants is for Cheng Yang, a person who has always been very indifferent, to take the initiative to treat him, and from the perspective of a friend, he can easily get his wish.

"It's okay." His tone softened uncontrollably, "It's just recently... I haven't slept well recently, so I don't have a good attitude when talking to anyone. You know, it's those things. Yesterday my sister also criticized Me, saying that I was too aggressive on the phone."

Cheng Yang breathed a sigh of relief subconsciously: "Don't worry. Why don't you talk to Yao Lin again?"

This made Chu Shiqing startled again, and then that nameless loss washed over his entire consciousness like crazy.Chu Shiqing's heart felt as if it had been filled with lead.He didn't think of Yao Lin at all, and of course he didn't think of how reasonable it was for Cheng Yang to care about him now.

Maybe it's more of a friend's responsibility.

It's as if Chu Shiqing is quitting smoking now, and when he was addicted to smoking, someone took the initiative to stuff a cigarette into his mouth, and then he found that it was just a paper stick.

"Forget it, there's nothing you can do about it." Chu Shiqing suppressed his emotions, "I'm going to the summary meeting, so I'll hang up first."

After speaking, I hung up the phone, obviously in a bad state.Cheng Yang frowned, still feeling uncomfortable. After thinking about it, it was Chu Shiqing's tone of "There is no way to do this" that made him feel stuck in his throat.

Cheng Yang couldn't control his hand at all, so he called Yao Lin.

Statutory holidays are almost a nightmare for those working in the transportation industry.For the next week, Cheng Yang basically spent the high-intensity work with one break and one rest, and a big night shift every three days, which was particularly torturous.However, in the month after May [-]st, he couldn't go anywhere easily. He had to change shifts, paint a portrait of Chu Shiqing's sister, and prepare things for Europe.

When it came time to have dinner with sister Chu Shiqing, Cheng Yang was so confused that he almost didn't realize it.Because the time on the control seats is all UTC, people will have an illusion after watching it for a long time.

Chu Shiqing made an appointment to eat at a western restaurant in the eastern district.After Cheng Yang asked Yao Lin before, the other party expressed that he wanted to wait until the afternoon, and it happened that she was chatting with Chu Shiqing, and Cheng Yang was chatting with Chu Yunqing, otherwise it would be too embarrassing to sit and eat together.

Cheng Yang calculated the time and arrived 5 minutes early.When I arrived, I saw Chu Shiqing and a little girl already sitting in the booth.

Chu Yunqing and Chu Shiqing don't really look alike, but they feel very close to each other.When Cheng Yang walked towards them, it was Chu Yunqing who saw him first.Chu Yunqing recognized him almost instantly, and his eyes changed.Then she turned to call her brother, Chu Shiqing turned around and saw Cheng Yang.

Chu Shiqing didn't even show any expression, he just stood up and nodded to show that I saw you.

Cheng Yang walked towards them and gave them a smile.

"This is my younger sister, called Chu Yunqing. Zhu Junyun, Qing is my Qing." When Chu Shiqing mentioned Chu Yunqing, his expression softened a little, but he seemed to deliberately avoid Cheng Yang's sight, "She likes You have been around for a year or two."

Chu Yunqing said generously: "Mr. Cheng, hello."

As a result, Cheng Yang was so frightened that he quickly waved his hands and laughed.

"No, don't. Don't call me teacher, it sounds too scary." Cheng Yang said while sitting opposite Chu Yunqing, Chu Shiqing seemed to avoid him, "I'm really just a hobby, and I don't have any skills."

Chu Yunqing didn't refute, and nodded with a smile: "That's Brother Cheng."

"Okay, you can call me whatever you want." Cheng Yang turned his head and glanced at Chu Shiqing, "Your brother always calls me Director Cheng."

Chu Shiqing was stunned for a moment, his eyes were complicated, and he shook his head: "That's just for fun. You can call Cheng Ge."

After finally saying a word, I still said it to Chu Yunqing.

In Cheng Yang's subconscious mind, something suddenly became clearer.His heart sank, and he felt that he had done something wrong by calling Yao Lin over.

He had always thought that Chu Shiqing was broken in love before, but now it seems that the anger seems to be aimed at himself.

While thinking this way, Chu Shiqing suddenly stood up.

He was sitting on the inside, so if he wanted to come out, he had to wait for Cheng Yang to make way for him, which made Chu Shiqing very embarrassed.After standing up, he first picked up his coat and put it on his arm, then took a step forward, then backed away, frowning, but his eyes seemed to be very gentle when they fell on Cheng Yang.

"Then you can have dinner here. Yunqing said that she wants to treat guests, so don't be polite to her. My company has to go back in advance."

Cheng Yang was stunned.With his temper, if a friend has any misunderstanding or estrangement from him, he will generally respect the wishes of the other party and will not choose to forcefully solve the problem.If a friend can't get around that hurdle by himself, then it's because of fate. It's actually quite self-defeating to insist on pulling others to maintain a so-called friendship.

He frowned: "The company asked you to go back at 11:30."

It's unlikely that even an airline would handle that kind of non-flying business at mealtimes.

"Yes."

Cheng Yang had no intention of backing down at all.

"Sit down and eat before you leave."

Chu Shiqing's eyes changed: "It's urgent, I'd better go there."

In a word, none of the three present really believed that he would return to the company.Cheng Yang was a little annoyed, and withdrew his upper body to face Chu Shiqing, looking at him.

"Just say what you have to say."

Unexpectedly, Chu Shiqing sneered: "It's really fine. I just have to go back to the company—"

"Brother, let's talk after dinner."

Chu Yunqing's tone cannot be questioned, obviously speaking to Cheng Yang.Chu Shiqing was very dissatisfied with this behavior of emphasizing sex and despising family, and scolded me in his heart, thinking that even Chu Yunqing came to add trouble at such a time, which really gave him a headache.

When he was frowning and feeling agitated, Cheng Yang grabbed his elbow and motioned him to sit down. Chu Shiqing sat down before he could react.

"Let's eat first."

As Cheng Yang spoke, he called the waiter to order.

Seeing that the world is so malicious, Chu Shiqing no longer struggled, but just had a meal.After a while, the atmosphere at the table gradually eased, and Chu Shiqing did not reject Cheng Yang as much as he did at the beginning, and would occasionally intervene in the conversation between Cheng Yang and Chu Yunqing.Yun Qing looked very happy, the look in his eyes was different, and he chatted with Cheng Yang about the names of painters, Chu Shiqing basically couldn't understand.

As far as his judgment is concerned, Cheng Yang's knowledge of art is not as extensive as that of Chu Yunqing. At the end of the conversation, Cheng Yang didn't care much about eating, so he was serious with an expression of absorbing knowledge. Listen to Chu Yunqing speak.The whole person is very quiet, but his eyes are bright.The harmony between these two people seems to Chu Shiqing to have a different feeling. His mind cannot be controlled by himself and imagines what it would be like for Cheng Yang and Yun Qing to have dinner at home and discuss the painter.He felt that sitting next to him was very happy, but quite redundant.

But all unrealistic imaginations were shattered not long after they finished eating.

Chu Shiqing first heard the sound of high-heeled shoes from far to near, and when he looked up, he saw Yao Lin standing by their table.

He immediately looked at Cheng Yang, who was not surprised.

Chu Shiqing threw the water glass on the table and cursed: "Fuck!"

Then he stood up and looked down at Cheng Yang.

"Director Cheng, you are fucking insane, aren't you?"

Cheng Yang's face became ugly.It is estimated that he rarely put himself in such an embarrassing situation.Maybe he has never been so embarrassed in his life.

"Speak up if you have something to say, your sister is still here."

Chu Shiqing was about to open his mouth to refute, but Yao Lin spoke first.

"Shiqing, I'm here because I think we really need to talk. If you don't think it's necessary, I can leave now."

Chu Yunqing might not be able to stand it any longer, so she stood up and gave way to Yao Lin: "Sister Lin, please sit down first."

Chu Shiqing didn't speak, Yao Lin sighed and sat down. The waiter brought a glass of water in time and refilled the afternoon tea for several people.It took a few minutes of embarrassment in the booth, but Chu Shiqing didn't realize it, because he was still trying to calm down his emotions, and Cheng Yang didn't realize it, because he was thinking about how to apologize.

As soon as the waiter left, Cheng Yang stood up.

"Shiqing, Yao Lin, I did something wrong today. I'm really sorry for making you two so embarrassed. I really just saw that Shiqing's condition is too bad, so I don't think it's an option. But now it seems , It’s inappropriate for me to meddle in your affairs like this.” Cheng Yang paused, “I think I’d better go first. I can send Yun Qing home first, and you two can talk if you want to talk, and forget it if you don’t want to. .Isn't Shiqing still going back to the company?"

Chu Shiqing suddenly felt ridiculous after hearing the last sentence, so he laughed.

He smiled and shook his head.

"Cheng Yang, we can't be friends anymore."

Yao Lin was very anxious when she heard Chu Shiqing say this, and wanted to open her mouth to explain a few words, but she felt that something was wrong when the words came to her mouth, so she didn't say it.Chu Yunqing was really anxious, and said "Brother, don't do this" several times.

Cheng Yang didn't speak, but Cheng Yang looked sad and a little absent-minded.

Finally he nodded.

"OK then."

But after finishing speaking, he seemed to regret it again, and forced a smile: "However, let's wait until Yunqing's birthday is over. I happen to be going to Europe in June, so you don't have to avoid me."

Chu Shiqing didn't even look at him: "That's fine."

Cheng Yang was a little lucky at first, but seeing Chu Shiqing's reaction, he felt that he was really blind.He knew the pilot was an asshole when he first met him, but he still made friends later?

On the one hand, he was actually quite disappointed, and on the other hand, he was a little angry, so he turned around and left.Chu Yunqing subconsciously stood up.Seeing this, Chu Shiqing nodded at his sister: "Go with your brother Cheng and let him send you back. I have something to say to your sister Lin."

Chu Yunqing looked at him for a while, then at Yao Lin, then turned around and chased after Cheng Yang.

Yao Lin and the others were the only ones left, and no one spoke.Yao Lin looked at Chu Shiqing in disbelief for a long time, and finally, she only asked one question.

"Shiqing... I didn't read it wrong, did I?"

Chu Shiqing laughed after hearing this sentence.
