Chapter 27 Flap tilt

On the head of the runway No. 23, Qin Xin stood on the passenger elevator bus and looked at the Feiyu 6321 plane, which was getting lower and lower in the distance, feeling uncomfortable. At this time, even the secretary who didn't know how to fly could see that the Feiyu 6321 was incorrect.

"Why are their height so low?" the secretary was worried: "Can they still land on the runway?"

Almost a moment when the secretary's voice fell, due to the slope of the runway itself, the figure of the 737 disappeared directly on the horizon and in the sight of the two of them.

The secretary was so scared that he covered his mouth: "It fell down! The plane fell down!"

Qin Xin sighed quietly: "I shouldn't have come out."

In Qin Xin's opinion, the people on this plane were dead. Perhaps if they were lucky, how many people could survive. But she was not a person with a heart of heart, so she naturally didn't want to see such a tragic situation.

"Have the car arrived yet?" Qin Xin turned his head and stopped looking at the place where the plane fell: "It will be very messy here in a while, so it's better to leave earlier."

Suddenly, Qin Xin felt something in his heart, and he seemed to feel something.

Why is it so quiet? There must be some movement when the plane falls, why can't you hear anything until now?

Suddenly, Qin Xin saw the secretary's shocked side face and frowned: "What's wrong?"

I saw the secretary staring blankly into the distance, his slender fingers slowly raised and pointed to the distance: "Miss, it's up again!"

"What?" Qin Xin was shocked, turned her head suddenly and looked straight at the sky on the other end of the runway. With just a glance, her pupils suddenly shrank, as if she had seen the most terrifying thing in the world.

The plane that had disappeared from the heaven and earth line actually rushed into the sky again like the help of gods and entered the field of vision again.

"Impossible, why is this happening? It should have no motivation, why can it still get up?" Qin Xin held the railing of the passenger elevator car with one hand, and was so shocked that he almost stood unsteadily: "It shouldn't be like this, why is it like this?"

"It should be like this, it should be like this!" Xu Cang, who was sitting in the right seat in the cockpit, let out an almost crazy roar: "The sky will never stop me, the sky will never stop me!"

It was originally a dead end, but it was a turning point under the influence of an unexpected upward airflow.

Although the captain on the left was also very surprised, a layer of fine beads of sweat oozed out from the back. If Xu Cang hadn't hesitated a little about putting the flap and landing gear, as long as the flap and landing gear, especially the landing gear, were placed down, even if they encountered upward airflow, they would still be dead.

The landing gear and flaps will give the aircraft an additional uplifting moment the moment it is released, but this uplifting moment will not last for too long and will eventually turn into resistance.

"The height is three hundred feet, it's time!" Xu Cang curled his wild laughter and grinned his teeth: "Five Flaps!"

The captain was startled and calmed down, and immediately placed the flap from one position to five according to Xu Cang's request. However, before the hydraulic system had put the flap to five, Xu Cang went down another command: "Put the wheel, flap fifteen!"

In such cases, flaps are never the most important thing. The standard floor-standing configuration of single-engine is flap fifteen, but there is no standard double-engine failure floor-standing configuration.

The standards for landing of single-engines are different. There is no clear enough standard for landing of double-engine failures, because there is a strong component of luck in this case. Boeing even has no clear regulations on whether the double-engine failures should fall on the runway.

At this point, no matter what configuration you use, no matter where you fall, no matter what technique you use, as long as you can fall, that is the right way.

Since there is no standard for the position of the flap, you should understand what priorities are. And the worst thing is that the landing gear release lock takes time and you can't wait any longer.

Generally speaking, putting down the first-level flap only takes place after the previous level flap is put down. But this time, Xu Cang did not have such leisure and leisure.

The captain also took the initiative at this time and was still concerned about the others. He directly lowered the landing gear handle and placed the flap handle at the fifteenth position, regardless of the flap fingering.

In the middle of the movement, the plane fell another hundred feet. The captain did not forget his duties and quickly shouted on the passenger radio: "Two hundred feet in height!"

Then I touched the booster panel on the top plate with my right hand and wanted to close the component door first. But the moment I touched the component door switch, I remembered that due to the dual-engine shutdown, both components were no longer supercharged.

Logically speaking, the charge air in the cabin should have leaked at this time. However, the captain turned the booster mode selector to the manual station and turned the exhaust valve to the open position until the indicator indicates that the exhaust valve is fully opened.

Although this operation seems a bit redundant under the current situation, in some extreme cases, it may still be impossible to open the door due to pressure difference inside and outside the cabin. This happens when evacuating, which is really fatal, and the captain cannot let this happen.

With the release of the flaps and landing gear, the aircraft not only did not descend in a short time, but even leveled in an instant. However, with the disappearance of the fleeting upward airflow, the initial upward moment of the landing gear and flaps disappeared at the same time, and the aircraft began to enter the rapid descent stage after passing through the last two hundred feet.

Two hundred feet is only sixty meters, which seems not high, but it is still fatal!

"It's too fast, it's getting off too fast!" Xu Cang's heart tightened, and the vitality that had finally appeared was about to slip away. How could he let this happen? So he suddenly shouted: "Continue to put the flaps, flaps twenty-five, thirty, forty, don't stop!"

The captain's hand grabbed the handle of the flap without hesitation, but when he swept the airspeed gauge from the corner of his eyes, his pupils shrank: "No, the speed is too high, the flap will be unloaded."

In a low-altitude environment, the corrected space becomes smaller. Xu Cang uses the advantage of upward airflow to raise the aircraft speed to a normal range, so as not to affect the rudder effect of the aircraft if the speed is too small.

However, because the flap is too fast, the plane doesn't even have time to slow down. If the speed is too high, the flap is unloaded.

It was the captain's hesitation that made Xu Cang annoyed Xu Cang directly. Xu Cang yelled: "I don't care whether it is uninstalled or not, put it for me, and keep it to the end!"

The captain didn't say anything else, and began to put down his flaps as Xu Cang asked.

Xu Cang narrowed his eyes slightly, and life and death were successful and failed. But what he didn't know was that as the flap was released, the pointer on the flap finger table began to gradually fork.
