Return to 2000: Captain of the Great Powers

Chapter 27 Flap Deflection
At the head of runway 23, Qin Xin stood on the passenger elevator car and looked at the flying feather 6321 aircraft that was getting lower and lower in the distance, feeling uncomfortable.At this moment, even a secretary who doesn't know how to fly can tell that Feiyu 6321's altitude is wrong.

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

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

The secretary covered her mouth in fright: "It fell! The plane fell!"

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

From Qin Xin's point of view, the people on this plane were already dead, and maybe with luck, a few people could escape from death.But she was not a hard-hearted person after all, so she naturally didn't want to see such a tragic situation.

"Hasn't the car arrived yet?" Qin Xin turned her head and stopped looking at the place where the plane crashed: "It will be chaotic here in a while, it's better to leave earlier."

Suddenly, Qin Xin's heart moved, as if he felt something.

Why so quiet?There should always be some movement when the plane crashes, why can't I hear anything until now?
Suddenly, Qin Xin saw the shocked side face of the secretary, and couldn't help frowning: "What's wrong?"

I saw the secretary staring blankly into the distance, slowly raising her slender fingers, pointing to the distance: "Miss, it's up again!"

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

The plane that had already disappeared between the sky and the ground unexpectedly soared into the sky again like a god, and entered the field of vision again.

"Impossible, how could it be like this, it should have no power, why can it still get up?" Qin Xin held onto the railing of the guest elevator car, almost unable to stand still in shock: "It shouldn't be like this, why is it like this ?”

"That's how it should be, that's how it should be!" In the cockpit, Xu Cang, who was sitting on the right seat, roared almost crazily: "The sky will never stop me, the sky will never stop me!"

It was already a fatal situation, but it ushered in a turning point under the action of an unexpected updraft.

Although the captain on the left was also very pleasantly surprised, there was a layer of fine beads of sweat oozing from his back.If Xu Cang hadn't hesitated a little bit about lowering the flaps and landing gear just now, as long as the flaps and landing gear, especially the landing gear were lowered, even if they encountered updrafts, they would still be dead.

The landing gear and flaps will give the aircraft an extra pitch-up moment when they are released, but this pitch-up moment will not last long, and will eventually turn into drag.

"The height is [-] feet, it's time!" Xu Cang restrained his frenzied laughter and bared his teeth: "Flap five!"

The captain was startled, calmed down, and immediately lowered the flaps from one to five according to Xu Cang's request.However, before the hydraulic system could set the flaps to five, Xu Cang gave another command without stopping: "Put the wheels, flaps fifteen!"

Flaps are never the most important thing in a situation like this.The standard landing configuration for a single engine is flap fifteen, but there is no standard landing configuration for two engines failing.

Unlike the standard for single-engine landing, there is no clear enough standard for landing with two-engine failure, because in this case, whether you can land or not has a strong element of luck, and even Boeing has a decision on whether to land on the runway if the two-engine failure are not clearly defined.

At this time, no matter what configuration is used, no matter where it falls, no matter what method is used, as long as it can fall, it is the correct method.

Since there is no standard for the position of the flaps, you should understand what is the priority, and the terrible thing is that it takes time to release and lock the landing gear, and you can't wait any longer.

Generally speaking, it is necessary to wait until the previous flap is fully lowered before lowering the flap.But this time, Xu Cang was not so leisurely.

The captain is also going all out at this time, what else can he care about?Put the landing gear handle down directly, and put the flap handle to the fifteenth position at the same time, regardless of the flap index.

During the movement, the plane dropped another [-] feet, but the captain did not forget his duty, and quickly shouted on the passenger radio: "The altitude is [-] feet!"

Then the right hand touched the booster panel on the top plate and wanted to turn off the switch of the component first. It was only when the switch of the component was touched that I realized that the two components had not been boosted due to the flameout of the two engines.

It stands to reason that at this time, the pressurized air in the cabin should have leaked a lot.However, the captain still turned the pressurization mode selector to the manual position and turned the exhaust valve to the open position until the indicator indicated that the exhaust valve was fully open.

Although in the current situation, this operation seems a bit redundant, but in some extreme cases, it may still happen that the cabin door cannot be opened due to the pressure difference between the inside and outside of the cabin.And this happened during the evacuation, it is really fatal, the captain can't let this happen.

With the release of the flaps and landing gear, the plane not only did not descend in a short period of time, but even leveled off in an instant.However, with the disappearance of the fleeting updraft, the initial pitch-up moment of the landing gear and flaps disappeared at the same time, and the aircraft entered a rapid descent after passing the last two hundred feet of altitude.

Two hundred feet is 60 meters, which may not seem high, but it is still deadly!
"It's too fast, it's going too fast!" Xu Cang's heart tightened, the vitality that had finally appeared was about to slip away, how could he let this happen, so he suddenly shouted: "Keep putting the flaps down, Flaps 25, thirty, forty, don't stop!"

The captain's hand grasped the flap handle without hesitation, but when the corner of his eye glanced at the airspeed indicator, his pupils shrank: "No, the speed is too high, and the flaps will be unloaded."

In the low-altitude environment, the room for correction becomes smaller. Xu Cang used the updraft to increase the speed of the plane to the normal range, so as not to affect the rudder effect of the plane when the speed is too low.

However, the aircraft did not even have time to slow down due to the flaps being extended so quickly.With flaps [-] and [-], if the speed is too high, flap unloading will occur.

It was the captain's hesitation for a moment that directly annoyed Xu Cang, only to hear Xu Cang yell: "I don't care if it's unloaded or not, let me put it in until the end!"

The captain didn't say anything, and started to lower the flaps following Xu Cang's request.

Xu Cang's eyes narrowed slightly, life or death is a matter of life or death.What he didn't know was that with the release of the flaps, the pointer on the flap indicator began to gradually diverge.
