"Ye Qing, you should have heard just now. It is suspected that there is foreign matter on the road surface at the intermediate end or the stop end. The intermediate end is fine. What if it is at the stop end? There is not enough for you to stop, and something will happen." The tower commander said

said eagerly.

"Then determine for me whether it is at the middle end or the stop end. Now I am leveling out and flying a little further forward. You can quickly determine for me where the second foreign object is!" Ye Qing shouted: "My engine's

The speed fluctuation has become more and more obvious, and it won't last long."

Ye Qing's leveling off now means that he has to fly another quad temporarily, but now he is very close to the runway extension line. If he flies another quad, he will easily cross the runway extension line. He may need to do so later.

Cut it back.

However, these are all minor issues. Now, Ye Qing's engine speed has begun to show increasingly obvious instability. This is an extension of the instability of the oil supply system caused by the shortage of oil. From now on, anytime

It is not a strange thing for the engine to stall.

Flying out to another four directions is already the limit of time that Ye Qing can extend.

"Damn it, one more quadrilateral, at most one extra minute!" The tower commander was sweating on his forehead. With the current speed of Ye Qing's fighter plane, flying an extra quadrilateral would only buy them one minute.

The time, this is still the most optimistic estimate, may actually be less than a minute.

He scanned the runway just now and couldn't find the second foreign object at all. Now...the tower commander couldn't control it much anymore. He picked up the telescope and continued to scan the runway to determine the location of the second foreign object.

"Is there such a thing? Don't let that person make a mistake." The tower commander kept mumbling.

To be honest, what Xu Xian said just now was that he could only determine the location of the first foreign object part, and the tower commander did know it. But Xu Xian himself was not sure about the second foreign object part. This kind of uncertainty is the most

It's annoying. Just because of this uncertain possibility, Ye Qing now has to face the risk of the engine stopping at any time to find this thing that he doesn't know exists or not. It's really a bit stressful.

"Damn, damn, where are you?" The tower commander was extremely anxious. Suddenly, a person rushed into his field of vision.

This man was wearing a civil aviation pilot's uniform, with a reflective jacket on top, and was running on the apron towards the runway.

"Is it him?" The tower commander's first thought was the crew member who had just alerted him on the frequency that there was a foreign object on the runway. But, what does he want to do now?

On the stairs of the covered bridge, the ground service personnel had not yet recovered from the violence Xu Xian had just done.

Just now, Xu Xian not only snatched her walkie-talkie, but also took off her reflective clothing. Xu Xian put on the reflective clothing, grabbed the walkie-talkie, got off the airport, and without saying a word, walked towards

Running fast on the runway.

Bisu Airport is very small, and the distance between the apron and the runway is very short. If you run to it as hard as you can, it won't actually take much time.

Originally, the ground service personnel wanted to catch up, but she still remembered the on-site commander's request that no activities on the apron were allowed. But in the blink of an eye, Xu Xian grabbed her walkie-talkie and reflective clothing, and walked off in a big way. Not only was she on the plane

The plane is moving, and it seems to be rushing towards the runway. Isn't that asking for death?

It's okay for Xu Xian to seek death, but don't drag her down!

However, as soon as the ground service personnel started to move, they were held by Qin Zongyang's big hand. Qin Zongyang smiled at the ground service personnel: "If something happens, he and I will take the responsibility, so you won't be affected.

Yes. Just wait here and don't affect him."

"But..." Ji Fu was still a little worried.

However, Qin Zongyang waved his hand: "Let him go, you can't catch up now."

Xu Xian's movements were extremely fast and violent, like a cheetah jumping out. It was just a dazzling move. Now he was almost close to the runway. For the ground service personnel to try to catch up with Xu Xian, it was nothing more than a dream.

"You can remember what I just said!" The ground service staff grabbed Qin Zongyang's sleeve with her backhand, as if she was afraid that he would run away. The ground service staff was really afraid that Qin Zongyang would run away. If the airport authorities launched an attack to investigate, she would drag Qin Zongyang away.

Come out to take the blame.

Qin Zongyang was dumbfounded by the ground service personnel. He took out his boarding pass and showed it to the ground service personnel: "This is my ID. Why don't you send someone to take a photo so that I can't run away."

The ground service staff was startled for a moment, then decided: "Just shoot!"

On the lawn next to the runway, Xu Xian anxiously searched for the possible location of the second foreign object. He tried hard to recall the location where the second foreign object fell. However, no foreign object was found on the runway surface it corresponded to.

Traces.

"Where is it? Where is it!" Xu Xian gasped for air, and he could vaguely feel the smell of blood in his mouth. He hadn't exercised so strenuously for a long time, and such a sudden rush was too much for his body.

Especially in his chest, Xu Xian felt as if there was a huge boulder pressing down on him. Even though he tried to breathe hard, he still felt out of breath.

"Tower, I have to turn back. The engine speed has begun to drop uncontrollably. I can't wait any longer." Ye Qing looked at the indication on the engine speedometer and his eyelids couldn't stop twitching.

Just now, the engine tachometer only showed continuous fluctuations, but now the index is not only fluctuating, but also slowly declining amid instability.

The situation has become urgent. If it doesn't come to fruition, he will have no chance.

At this time, the tower commander could not stop Ye Qing. If the engine stopped, he would not even have a chance to land.

"024, are you going to ground as originally planned?" the tower commander had to ask.

The so-called original plan was to touch down in the middle of the runway as the tower commander just said, so as to pass over the first foreign object on the runway.

"That's right, I landed in the middle of the track. Let's just pray that the second foreign object is also in the middle, or that it didn't fall on the track."

To be honest, if the engine was not about to stop due to lack of oil, Ye Qing would not be willing to land on the second half of the runway where the road ahead was unknown.

"Tower, how far is the first foreign object from the end of the runway?" Ye Qing suddenly asked.

"Visually observing six hundred to seven hundred meters, what do you want to do?" The tower commander didn't understand what Ye Qing meant by asking, and immediately reacted: "Ye Qing, a distance of more than six hundred meters is definitely not enough.

You should give up this idea as soon as possible."

The tower commander was afraid that Ye Qing planned to use the more than 600-meter runway in front to land. This 600-meter runway was indeed completely safe, unlike the second half of the runway where the situation was unknown.

However, a distance of more than 600 meters is simply not enough for this fighter to land. This fighter is a twin-engine heavy fighter, and it is simply fantastic to complete the landing deceleration at a distance of more than 600 meters.

In the view of the tower commander, instead of dreaming about completing the landing deceleration in the first 600 meters or so, it is better to bite the bullet and try it on the second half of the runway.

After all, among the three possibilities of the second foreign object landing at the middle end, the stopping end and outside the runway, as long as it is not the stopping end, it will not have an impact on the landing. There is at least a two-thirds possibility, and in comparison

In order to complete the landing within the first 600 meters, the maneuverability is more than a bit greater.

At this point, with the fuel alarm problem pressing down, there is no foolproof solution, and we can only find a relatively more successful solution.

"Have you visually noticed any foreign objects on the second half of the runway?" Ye Qing asked. Regarding the matter of landing on the first 600-meter runway, Ye Qing seemed to have just stopped there and did not bother with the tower commander at all.

The tower commander saw that Ye Qing seemed to have given up this crazy idea, and he breathed a sigh of relief: "No, maybe the crew member just made a mistake."

To be honest, the tower commander himself did not believe that parts of the fighter jet would fall off twice. You must know that although this fighter jet is a prototype and is far from finalized, the strength of the aircraft body has been verified in previous test flights.

, it is not difficult to withstand a load of more than 10G. How is it possible that a heavy landing can knock off the body parts?

It is extremely rare to knock off one part. If it knocks off two parts, what is the difference between being struck twice by lightning?

Therefore, the tower commander deduced based on common sense and felt that the crew member who reported the report had made a mistake. Moreover, he did not look at it, so he instinctively felt that the so-called second fallen part was a fiction.

"No, I didn't make a mistake!" At this time, Xu Xian's sharp gasping sound suddenly came from the channel, mixed with his anxious voice: "I saw a foreign object at the end of the runway, and I can't use the second half of the runway to land.

!You can’t use the second half of the runway to land!”

Xu Xian was always holding a walkie-talkie, so he could clearly hear the conversation between the tower commander and the fighter pilot, and he also knew the plan they had discussed to use the second half of the runway for touchdown.

However, now that a second foreign object has finally been discovered at the end of the runway, the original plan to land on the second half of the runway is not feasible.

"Impossible! What position!" The tower commander was horrified when he heard this. All he could see was that the pilot in reflective clothing was moving from the end of the runway, along the edge of the runway, towards the circle in the center of the runway.

Logo running wild.

"I don't know, I'm not sure, I'm going to pick things up." Xu Xian yelled at the intercom.

He was limited by vision problems and was not as condescending as the tower commander. He could use runway markings to determine the location of foreign objects in parts. He could only estimate the approximate location of foreign objects in parts based entirely on feeling.

However, even if he could tell the exact location of the foreign object, it would not change the situation. The only way to help now is for Xu Xian to pick out the foreign object before the plane lands, so that he can have a chance to crack it.

But this foreign object seemed to be not far away, but when running, it felt far away, quite like looking at the mountain and running to death.

"Can it be reduced to the minimum speed? Just keep it from stalling!" Xu Xian looked towards the enemy fighter that was already very close. He could even hear the roar of the fighter engine.

Xu Xian said this to the fighter pilot Ye Qing. He hoped that the fighter jet could reduce to the minimum speed, which is the minimum speed in the true sense, that is, an airspeed value that is only slightly larger than the stick shaker speed, rather than establishing a good landing.

Standard approach speed after configuration.

However, there is not much difference in speed between the two. Even if Ye Qing lowers the airspeed, the time he can buy for Xu Xian is not much. It can even be said to be negligible. Because the five sides that this fighter cuts into are too short, a little bit

The speed difference will not cause an obvious difference in grounding time.

Perhaps he was running too hard, and Xu Xian's voice on the intercom was like a leaky bellows, as if Xu Xian was going to run away and die in the next second.

"Brother, stop running." Ye Qing lowered his gaze and scanned the entire runway. Under the sunlight, he noticed an unusual reflected light near the middle of the back half of the runway.

He knew that the location of the reflected light might be where the foreign object fell from the second part.

Some parts on the fighter jet are polished and polished to an extremely smooth surface. The entire part looks like a mirror, and it is not unusual for it to reflect sunlight.

Ye Qing briefly compared the location where the second part fell with Xu Xian's position, and he knew that Xu Xian was determined not to pick out the part before the plane landed.

"I saw it, you were too late!" Ye Qing was relieved at this time: "I won't touch down in the second half of the runway."

Hearing this, Xu Xian suddenly stopped and looked up, only to see the nose of the fighter jet plummeting down and its point of contact beginning to move rapidly backwards.

The change in the fighter's posture was naturally clearly seen by the commander on the tower. At this moment, almost all the hairs on his back stood up, and he suddenly shouted into the frequency: "Ye Qing, what do you want to do? Are you here?

To which point?"

Whether it is civil aviation or military aviation, pilots should know where their touchdown point is before landing. The most common touchdown point is what is commonly known as the "big white patch."

In visual flight, when the altitude is slightly higher, you can first follow PAPI, etc., or simply calculate the standard altitude of the corresponding distance based on the glide gradient. But when it comes to low-altitude environments, it is almost 60 meters or less than 200 feet.

Altitude is the decision altitude for a type of blind landing. Below this altitude, the pilot begins to switch to visual sight, and at this time the pilot will gradually begin to perform point alignment work.
