C1488

Xiao Peng and Eminem looked up together. After seeing the situation in the sky, they stood up together and looked serious.

"The plane stalled!" Am exclaimed.

It has been more than 100 years since the birth of aircraft that "stall" is a nightmare in flight.

Stall means that all the lift on the wing is lost during the flight, and the aircraft will stall in the sky. If it is not solved quickly, the aircraft will enter the "deep stall" spiral roll state, also known as the death spiral. A plane in a deep stall state usually means a crash.

This stall is not like in the movie, stall can still keep gliding state, but in the sky irregular roll. Imagine throwing a model airplane vertically from the sixth floor. Can it glide? At this time, the pilot must hurry to operate, let the air flow through the wing to regain the lift in order to release!

In fact, the main reason for this is not the increase in the angle of attack. Therefore, the aircraft should maintain a smooth flight when flying. It is easy to cause stall when flying like that.

"Pull it up Yang Meng cried out anxiously there.

Eminem shook his head: "push or pull. That's not reliable in the movie. You forgot? My daughter and I have a small plane license

When we watch movies, we often have this kind of bridge: when the plane stalls and is about to crash, the pilot pulls the control lever desperately. And then he yelled "pull up and pull up." and the moment the plane crashed, the plane miraculously returned to normal flight and flew into the sky.

If that's true, it's a miracle.

Although it is said that pulling up the control lever is raising the nose and pushing the lever is nose sinking, the correct way to deal with the stall condition is to push the lever instead of pulling it.

This is to find the right angle of attack of the wing and allow the aircraft to regain lift.

In line with the principle of "the air force pulled out the stall control lever" in the early days of World War II, but he did not use the stick to deal with the stall until the early stage of World War II. From then on, people found that - Oh, it turns out that in such a situation, it's pulling or not pushing.

With the progress of science, in order to prevent the aircraft from entering the stall state, a stall protection device appears. It will give the pilot a warning. When the angle of attack is too large, the aircraft control lever will shake violently, and tell the pilot not to pull the nose up any more and speed up, otherwise it is easy to stall.

For example, the Boeing 737max is prone to nose pull-up, and the function of MCAs system is to force the control lever down to make the aircraft bow down. However, the aircraft gets on and off, and it's easy to enter the stall state.

Just like we laugh at the crash of Indian III pilot all day long, there is another important reason besides the aircraft. In fact, stall is very easy to happen. Sometimes there is only two degrees of angle of attack difference, sometimes it is only 20 km / h speed difference, the aircraft may enter the speed state, especially when taking off and landing, the pilot may make a mistake The plane will stall!

Xiao Peng looked more and more heavily: "deep stall. What are you doing here? Quickly rely on the past to find a way to rescue ah! Congcong, what else do you take? "

Eminem stood there with a dull face: "where to rescue? Are they at least dozens of kilometers away from us? "

Xiao Peng came back to his senses and wiped it. Although the plane was visible to the naked eye, it was still ten thousand meters high. With the inertia of falling, where would it fall? Even if your boat is fast, it's too late to go now, right?

"Am, you're right Xiao Peng nodded: "but we can't stand by! Wang Hu, get the helicopter ready! Huang Bin, all lifeboats and other preparations, Xiaoqiu, as well as you, what emergency measures are ready, in case you need to use them later? Fierce son! Speed up the boat, follow the plane and tell them what's going on here! Let Professor Luan and all of them return to the cabin. Don't join the party now

"Yes All the people on the boat were in their places.

Eminem and Qian congcongcong asked with one voice, "what about me?"

Xiao Peng thought for a while: "you just live well."

The two men compared the middle finger of Xiao Peng. But still followed Xiao Peng back to the cockpit.

After Xiao Peng went back, the first thing he did was to contact the coast guard to call the police.

"Coast guard! This is four seas quest! Coast guard! This is four seas quest! Answer when you hear it

As a result, half a day later, a man's voice came from the walkie talkie: "Oh, the famous four seas exploration is coming to contact us? I don't know what's going on? Will you call for help, too? Or do you want more money? " Xiao penggang has made the coast guard look pale. It's strange that they can be polite to Xiao Peng.

Xiao Peng snorted coldly: "I contact you to tell you that an airliner is falling at a deep stall. You'd better go to the position 110 nautical miles west of Aleutian Islands, and the coordinates areXiao Peng's words have not finished, the opposite man directly interrupted his words: "did the plane crash?"

"Not yet!" Xiao Peng answered honestly.

"So what do you contact? The plane crashed! Do you know, if you have an uncertain phone call, we will send someone! Do you know how much manpower, material resources and funds will be wasted? Our coast guard uses the money of star states taxpayers, not for waste The other side cut off the call. Let Xiao Peng and others look at each other.

After a long time, Xiao Peng came back to his mind: "am, you people in xingtiao country are so wayward?"

After hearing this, Eminem yelled: "who is this, Vacco? Is he going crazy? He doesn't know what he says? Xiao, give me your satellite phone! "

Xiao Peng took out the satellite phone and didn't know what he was going to do.

As a result, Eminem contacted the reporters directly. The coast guard didn't take this matter seriously. The reporters paid attention to it!

"Boss, the helicopter is ready!" Wang Hu said in the walkie talkie.

After hearing this, Xiao Peng asked, "did you check the rescue winch equipment?"

Wang Hu nodded: "no problem. It's all checked. "

Xiao Peng turned around and was about to leave, but he tilted his head and looked at Eminem and Qian congcongcongcong and said, "don't be idle. Follow me to the helicopter and help operate the winch. Am, aren't you afraid of heights? "

"No! Is there a problem? " Eminem was puzzled.

"That's all right. You may be used later! Let's go Several people boarded the helicopter together, ready to chase the direction of the crash.

At this time, in the coast guard reception center, a man was flirting with a middle-aged female soldier.

The woman said with a smile, "honey, you are too bad! I'm going to hang them up? "

The man snorted: "baby! I'm not angry not to mention them! Because of them, I can only stay in the base now, so many mission subsidies I can't get! Hum, the head is also a bastard! I thought I could take over the captain after Henderson was driven away. What happened? "

The woman blinked: "Walker, is it because you don't want to see me here? So we don't spend more time together? Or are you out there? "

It turned out that this man was no one else. It was walker. After Henderson was forced out of the army, Walker was punished because he was not on the ship at that time. However, he was better. He was not forced to be in the team, but he could not continue to stay on the ship. Without navigation subsidies, his income was greatly reduced. Can he be angry?

"Honey, what do you say? I swear to God, I only have you except my wife! I'm not angry that I can't buy you more presents because I don't have a lot of income. " Walker quickly laughed at the woman soldier. However, he also sighed in his heart that the sixth sense of the woman was really cow!

You're the only woman? How can it be! There are only zero and infinite results for such things as man's infidelity. Some things are addictive.

The woman gave him a blank look: "you can talk

Walker turned his eyes. "Honey, is the surveillance still bad here?"

"What do you say?" she said with a smile

Walker's eyes lit up: "what are you talking about? This is not the time to speak, will you? " Then she picked up the woman and threw her on her desk.

The woman said in a hurry: "lecher, what's the hurry? At least lock the door

Walker said with a smile, "if you can't get anyone here for a hundred years, what are you worried about?" Then he put his hand into the woman's clothes......

When they can't be happy here, some people are.

Who's upset? South Coast Guard commander hooker..

He is now holding the phone, a face confused: "what do you say? You're not teasing me, are you? "

"It's really not. Matthew Lee asked about this issue in public at the White House press conference. We also contacted the civil aviation department. A civil aircraft of Southwest Airlines to Ted Stevens Anchorage International Airport has lost contact. As you know, our agency department, Changsha nahan, was the vice president of Boeing. You are in big trouble about this matter. I think we have a good relationship before we secretly contact you! " Said the phone.

"I really don't know anything about it!" Huck said

"Come on, it's not the time to talk about it. You should find out what's going on now! You don't know what happened in your jurisdiction, but the reporter knows it. You know how passive it is

Hooker took a gulp. "Did the discoverer not contact the coast guard, but the reporter directly?"

"Damn it, didn't you listen to me? It's the coast guard that they contacted after you said they didn't care about it! "

"Putong.". Hooker just fainted to the ground, which was a total trouble.
