Return to 2000: Captain of the Great Powers

Chapter 76 I am indeed the strongest! (Please subscribe!)

In the simulated cabin, Jin Fuli and others who had planned to leave all fell into dead silence.Even Jin Fuli, who had been sitting all this time, stood up and stood behind Xu Cang, quietly watching Xu Cang's operation.

Xu Cang's operation is not complicated. He maintains the green dot speed as before. After all, the green dot speed in the manual is not the ground speed, but the true air speed. He does not need to correct his speed according to the wind.

But this does not mean that the headwind has no effect on the aircraft, the speed remains the same, but the rate of descent is therefore greater than that under no wind conditions.

Generally speaking, this rate of descent should be around [-] to [-] feet per minute, but under the influence of the headwind, this rate of descent increased to more than [-] feet.

Although the difference in the rate of decline is not very big, it is fatal at this moment.Even as the altitude decreases, the rate of descent will gradually return to the value it should be.

In fact, in a real flight, due to the increase in air density in a low-altitude environment, the aerodynamic performance of the aircraft increases, and the descent rate of the aircraft should also decrease theoretically. However, the simulator cannot simulate it, so naturally it is not considered. within.

Whether it's Jin Fuli, the seventh-level co-pilot, or the remaining two low-level Airbus trainees, they can't imagine the trajectory of the slide under the change of wind speed. Fly to this field.

Intuitively speaking, it seems that the aircraft under the action of the headwind really cannot fly to this field.But as the altitude decreased, Jin Fuli and the Airbus trainees began to have a feeling out of thin air, could it be that the plane could really fly to this field?
The plane didn't seem to be losing altitude as fast as they thought it would.However, even with this feeling, the altitude of the plane is actually quite dangerous, but the ideas of a few people are not as firm as before.

But in their subconscious mind, they still don't believe that they can do this mentally, and they prefer Xu Cang to be completely fooled.

At an altitude of about [-] feet, the cadet in the right seat should have informed the cabin of an imminent landing.But a group of people were all looking at Xu Cang intently, so why not notify the cabin?
The altitude of 4.8 feet is already a very low altitude, and the whole picture of the runway of Jianchuan Airport can already be seen relatively clearly from the scenery of the simulator.But now judging from the instrument, the plane is still [-] nautical miles away from the runway, so the plane is actually [-] feet higher than the best glide path.

What is the concept of eighty feet?That is more than 20 meters, and with a slight shake of the hand, the height margin is gone.But the problem is, even if you choose to land in a smooth configuration, the landing gear must be put anyway.Once the landing gear is lowered, the height of eighty feet is simply not enough to consume.

"What are you going to do?" Jin Fuli put one hand on the back of Xu Cang's chair, staring intently at the altimeter and DME display, and kept calculating the altitude ratio in his mind.

In fact, even now Jin Fuli is still quite pessimistic about Xu Cang.It is said that there is still a margin of [-] feet in theory, and at an altitude of [-] feet, the headwind has basically disappeared, but in the end this is theoretical, as long as the speed changes by one or two knots, the height of [-] feet I can't keep it.

The more Jin Fuli calculated, the more difficult he felt, so he asked: "Are you going to put the flaps?"

Flaps can provide lift and drag at the same time, but at the beginning of release, they will provide an additional pitch-up moment to the aircraft, which is a helpless means of life-saving.Previously, Xu Cang had used this method to save his life when Feiyu 6321's twin engines were turned off.

Jin Fuli's idea is also very simple. When the height is not enough, use the flaps to let the plane arch forward. If you are lucky, you should be able to land on the runway, and the probability is not low.Because Xu Cang maintained his speed quite perfectly, almost always on the best downward trajectory, without moving a bit.

"The flaps can't be released, and I can't control the state of the plane after the flaps are released." Of course Xu Cang knew that releasing the flaps at a critical moment would allow the plane to land on the runway, but the problem is that now not only must it land on the runway, but also It must land precisely on the head of the runway, on the zebra crossing sign at the entrance of the runway.

Due to the high approach speed, according to the verification of the landing distance table, the length of the Jianchuan runway is adequate, which is very dangerous.If you touch down in the normal touchdown area, you will lose some runway length, which is not enough to stop.

The release of the flaps will raise the aircraft in a short period of time. This is not a sophisticated operation, but there is no quantitative standard for how strong the lift is and how strong the energy is. This is beyond Xu Cang's control.

Moreover, the flap must be released at the last moment, because once the flap is released, its initial lifting moment disappears, and the resistance generated by itself will be greater.The pilot must take advantage of the greater resistance to touch down before coming.

There will be a problem if the timing of flap release is put at the end, Xu Cang has no extra time to correct the state of the aircraft.If there is no time to correct the aircraft state, the initial lift moment generated by the flaps is likely to cause the aircraft to float flat for too long, and it will not be able to touch down in the runway threshold area at all.

The release of the flaps will produce unforeseen state changes. For an aircraft with no power and no timing for correction, such uncontrollable changes will have a great negative impact on precise operations. Xu Cang will not allow such things happen.

Jin Fuli understood Xu Cang's thoughts, but knowing it was one thing, and doing it was another thing: "If you keep the flaps up, you have to put down the landing gear, right? What about the altitude loss?"

"Then delay the release of the landing gear until the end as much as possible." Xu Cang licked his chapped lips subconsciously, and it was obvious that at this stage, even Xu Cang felt pressured.

Compared with the obvious lifting moment when the flaps are released, the release of the landing gear will also have a similar effect, but the duration is shorter and the effect is worse, but this is exactly what Xu Cang needs.

This kind of lifting effect can exist, but it must not be too strong, otherwise it will be difficult to control.So now the question is when to put the landing gear?
You should know that the flaps can generate drag and lift at the same time, but the landing gear can only generate resistance alone, which is why some pilots use the early release of the landing gear to slow down or increase the rate of descent.

Therefore, compared with the flaps, the release timing of the landing gear needs to be delayed more, otherwise the unpowered aircraft cannot withstand the strong resistance generated by the landing gear.But the problem is that the release timing of the landing gear cannot be too late.Because the release of the landing gear takes time, if the timing is not accurate, the landing gear is not fully extended at the moment the plane touches down, which will be a fatal problem.

Jin Fuli could understand what Xu Cang meant, but the timing of the release of the landing gear was too difficult to grasp.But this time Jin Fuli didn't question Xu Cang anymore, he stood quietly behind Xu Cang, waiting and watching.

Five hundred feet high!
Xu Cang straightened his upper body, and this movement of changing his sitting position was an obvious manifestation of psychological anxiety.However, Xu Cang was quite forbearing, with no obvious expression on his face, he said flatly: "Pull the landing gear and listen to my password, the speed must be fast!"

The student seated on the right is a typical representative of those who don't know and are fearless. This kind of extremely high-precision operation has far exceeded their own ability, so they simply don't think about it anymore, and only need to follow Xu Cang's instructions.

"Okay!" The student on the right quickly responded.

The altitude is two hundred feet, which is already below the decision altitude in the blind descent, and it has begun to turn into the visual stage.From the set, the first half of Jianchuan Runway 05 has been clearly displayed in front of Xu Cang.

As the landing approached, even people like Jin Fuli swallowed unknowingly, feeling extremely nervous.

One of the problems caused by Xu Cang not letting go of the flaps is that the speed is too high, which in turn causes a very high rate of descent.Moreover, in order to be able to fly to this field, Xu Cang needs to maintain this high descent rate to an ultra-low altitude.How to turn the plane from an obvious head-down attitude to a grounding attitude when it touches down also depends on Xu Cang's technique.

If the hands are not good enough and the front landing gear touches the ground first, it will undoubtedly end in a plane crash.

Just when the plane passed an altitude of [-] feet, the tense simulated cabin atmosphere was suddenly broken, and Xu Cang shouted suddenly: "Stop the wheel!"

The student in the right seat who had been waiting for a long time heard this order and put down the landing gear almost reflexively.Following the release of the landing gear simulated by the simulator, the plane really began to look up slightly.

From [-] feet to touchdown, the aircraft's descent rate at this moment is only seven or eight seconds.However, the release of the landing gear also takes time, it depends on whether the timing of the two can be matched.

The altitude is fifty feet. According to the normal descent trajectory, the aircraft has already entered the air above the runway at this altitude, but at this moment the aircraft is still a short distance away from the runway.

The small pitch-up moment from the initial release of the landing gear was definitely felt, and slightly dampened the sinking of the disembarking aircraft.However, as the part of the landing gear was gradually released, this weak pitch-up moment disappeared in an instant, and it only existed for less than two or three seconds, and the sinking of the aircraft began to gradually return to the previous level.Moreover, when the landing gear is fully extended, the sinking will continue to increase, estimated to reach [-] feet per minute, Xu Cang obviously will not allow this kind of thing to happen.

At this moment, seeing that the plane hadn't reached the runway yet, Jin Fuli couldn't help feeling a little flustered, and couldn't help it: "You can't fly, let's put the flaps!"

"No, that's not right! It's definitely not going to fly." The seventh-level co-pilot almost judged Xu Cang's ending with an extremely certain tone.From a visual point of view, no matter from which angle, it is a dead end now!

However, Xu Cang just said calmly: "Look!"

At this time, the descent rate of the aircraft was indeed very high, but the speed was also very fast!People like Jin Fuli's usual approach speed is almost more than 50 knots slower than now, so it is easy to make a misjudgment from a visual judgment.

The altitude is indeed dangerous, but at high speed, the plane will approach the runway faster, which Jin Fuli can't feel or feel is not so accurate.

However, in fact, it cannot be said that there is anything wrong with what Jin Fuli or the seventh-level co-pilot said.Because Xu Cang could figure it out in his heart, the plane was still a little short, and indeed it couldn't reach the runway.But this is fundamentally different from the cognition of Jin Fuli and others. Those people guessed and were not sure, but Xu Cang calculated and was sure.

Almost at the moment when Xu Cang's voice fell, the last white PAPI light turned red, and all the PAPI lights turned red, which indicated that the altitude of the plane was obviously lower than the normal glide track at this moment.

From the visual point of view, Jin Fuli even had the illusion that he was on the same level as the runway, which shows how low the plane is.

With the report of the radio altimeter, at the radio altitude of [-] feet, the nose landing gear has just been released and locked, and the two main landing gears have not been released and locked. At this time, the aircraft's descent rate is still [-]. foot.

According to the normal ground sinking, the descent rate should be reduced to about [-] feet per minute at this time.With a descent rate of [-] feet, the difference between the plane and the crash is not very big.

The two Airbus trainees watching from the back saw that it was frightening. At a radio altitude of [-] feet, the two main landing gears had not been released and locked, and the sinking was ridiculously fast. Could this plane fall?

At this moment, Jin Fuli really admired Xu Cang's ability to hold his breath. He has reached a height of twenty feet. Isn't this level?
However, the moment Jin Fuli had these thoughts, Xu Cang finally got rid of the green dot speed.He took the pole suddenly, and the movement was extremely fast.

It is definitely not possible to pull the stick like this normally, but at this moment, the aircraft should instantly change from a downward attitude of about minus 1 degree to a normal landing attitude of about 4 degrees.

Xu Cang's shot almost leveled the plane. In view of the high speed of the plane, the leveling of the plane only produced an effect similar to a one-meter leveling under the condition of losing speed.

Originally, it seemed that it would not be able to land on the runway, but in this way, the plane actually slid into the air above the runway in a state similar to floating.

However, this state cannot last for too long.Leveling off without power will cause the speed of the aircraft to decay rapidly, and without the cooperation of the auxiliary lift device, in a low-speed environment, the aircraft's speed has not been reduced to the stick shaking speed, and the level flight cannot be maintained.

After leveling off for less than two seconds, the plane turned to sink again.Just as the plane was sinking, the two main landing gears were just lowered and locked. The plane almost entered the sky above the runway and landed on the zebra crossing mark at the entrance of the runway. Even the people in the simulated cabin did not feel obvious grounding sense, it is estimated that the ground load will be below 1.2G.

The moment the plane touched down, because both engines were turned off, the reverse thrust was useless, and the manual brake was applied to a rough stop. After the stop, the parking brake was set, and without speaking, just took off the earphones and leaned quietly on the seat superior.

"Is it landing?" The seventh-level co-pilot of the Airbus still couldn't react. When he was at an altitude of fifty feet just now, he could clearly feel that the plane had landed hopelessly.Who knew that Xu Cang even made a standard [-]-meter leveling when he barely reached the runway, forcing a wave of life for the plane that was already in a deadlock, which was simply the finishing touch.

Not to mention that the seventh-level co-pilot felt that this landing was a bit dreamy, even a veteran like Jin Fuli felt incredible.Finding a ray of life in a desperate situation, the performance presented is so light that it is so simple that it feels unreal.

And, that's not the worst.At an altitude of about [-] feet, all of them felt that the plane would not be able to fly to the field under the action of the head wind.But Xu Cang calculated in his mind that the plane could fly to this field based on the uniform change of the wind speed of the simulator itself.

And it turns out that, despite a tiny margin of error, the plane did almost make it to the field.Those tiny inaccuracies can be completely ignored in front of Xu Cang's performance.

"Can people really calculate all these things?" Even though the facts are in front of him, Jin Fuli is still unwilling to accept the nonsense that Xu Cangxin calculated the plane's descent trajectory.If it were him, even if he was given a computer, he might not be able to figure it out.

And on the eve of landing, Xu Cang's [-]-meter flattening formed by relying on the high speed of the plane itself was a flash of inspiration, extremely exquisite.As for the two main landing gears that were put down almost immediately before touchdown, Jin Fuli was already a little numb.

For some reason, he suddenly felt chilly.Perhaps, Xu Cang is really lucky, but it is more likely that he can really control everything.

It is impossible to be reached by manpower, this sentence does not seem to apply to Xu Cang.

Looking at Xu Cang leaning on the chair with his eyes closed, Jin Fuli suddenly trembled slightly after a short period of fear.

Perfect!Simply perfect!The ability and talent that Xu Cang showed at this time has far exceeded his previous expectations, reaching an almost unbelievable level.

To get such an apprentice, he would have no regrets in his life.

However, Xu Cang, who was breathing softly at this moment, slowly released the left side stick.He hadn't been so excited for a long time. Even though later generations achieved the position of the Chief Master of the Bureau, Xu Cang felt bored from the long and stable life.

Just now, Xu Cang completed a project that Jin Fuli and everyone else thought was impossible, which also inspired Xu Cang's silent pride from the bottom of his heart.

A genius is never humble, if he is, it can only show that he is not a genius!

Xu Cang has not been competitive for a long time, everything about flying is always as simple as eating and drinking in front of him, who would feel excited because of eating and drinking?

But the miraculous operation just now really made Xu Cang find the fun of flying.

He straightened up slowly, lowered his head silently, and the corners of his mouth slightly raised. Even though he was as calm as him, he still couldn't help feeling proud at this moment, as if he had returned to the feeling he felt after flying solo for the first time in aviation school.Suddenly, Xu Cang said in a volume that only he could hear: "I am indeed the strongest!"
