The climate deep in the land is completely different from that at sea. Hainan pilots have almost never flown in snowy weather, and the areas they stay in are usually hot and hot.
One of the similarities between the land and sea covered in ice and snow is that they have almost the same color. It is difficult for pilots to distinguish between sky and earth/sea. If they make a mistake, they will plunge headfirst into the ground or headlong into the sea.
Even though today's aircraft have very advanced avionics equipment, looking at past examples, landing in such weather conditions is still a great test for pilots.
Landing is always more difficult and dangerous than taking off.
The area where the test base is located has a very long winter. The test training time is tight and the tasks are heavy, so winter training must be carried out.
The ejection controller pressed the launch button, and the catapult pulled the No. 583 J-15S and threw it north. Within two seconds, the speed of the fighter jet reached 260 kilometers per hour. This take-off speed can easily lift more than 30 tons of aircraft.
The fighter planes were thrown into the sky.
No. 583 J-15S is equipped with four training air-to-air missiles, which simulates the air combat load. It carries standard fuel and the take-off weight does not exceed 30 tons. This is easy for the electromagnetic ejection system. However, the key is not take-off.
But it's landing.
This time Li Hai succeeded, which proved that winter training can be implemented and there are enforceable regulations.
Li Hai climbed as planned and flew northward against the cold wind.
The runway at the test base basically runs in a north-south direction. In winter, northwest winds and northeast winds blow, so takeoffs and landings are all facing north.
Real-time weather conditions were constantly reported from the ground, and Li Hai could see the specific data on the lower right color display. He did not dare to take it lightly, even though he had been stationed in Northeast China for a period of time and knew winter flight training well.
He conducted an hour-long air combat training in the northwest airspace 80 kilometers away from the test base as planned, and completed it smoothly.
The next return and landing is the key.
Looking down at the earth, it is completely white. The clouds in the sky are very thick and the area is very large. If you stare at a certain point for a long time, you will not be able to tell where is the sky and where is the earth, let alone the north and the south.
Under the heavy snow cover, there are almost no reference objects on the ground. Where is the test base, where is the fighter plane, and how much should the course, altitude and speed be increased? All depend on the avionics system. If there is a problem with the avionics system, then an accident is bound to happen.
Pilots must fully trust the avionics system.
Li Hai followed the instructions of the avionics system and returned to the test base. Ahead was a large cumulus cloud area. The radar showed that the test base was on the southeast side of the cumulus cloud area, a distance of twelve kilometers.
You can see the anti-collision lights on the top of the test base tower, if there is no cloud cover.
The airflow in the cumulus cloud area is not as turbulent as expected. Occasionally, when a burst of turbulence strikes, the automatic flight system will intervene to correct the attitude of the aircraft to ensure that the heading, altitude and speed are maintained at the set value. This function is a bit like the self-cruising system of a car.
There is a lane keeping function.
However, in combat, this system is basically useless.
Another burst of turbulence hit, and several lightning bolts suddenly appeared nearby. Li Hai walked directly through the lightning area without dodging, and he couldn't help but sigh softly. The appearance of lightning meant that snowfall was likely to fall soon, which added to the training.
some variables.
Soon, Li Hai saw the test base and immediately cheered up.
"Tower, I'm preparing to land." Li Hai reported.
Zhu Wei is in command at the tower. Today, only their experimental training group is flying. The 131st Tactical Attack Squadron of the Western Falcon Brigade's Mad Devil Brigade transferred to the ALD area early in the morning to perform missions.
Zhu Wei immediately replied, "You can land. Pay attention to the wind on the ground and the altitude."
"clear."
Soon, the people on the tower saw the No. 583 J-15S painted in earthy yellow. This color was more conspicuous in the gray sky.
The route of J-15S No. 583 was very standard. After making a large turn, the nose of the aircraft pointed north towards the runway. However, Zhu Wei was still worried. Before the plane landed safely, any accident could happen.
.
At this time, Li Hai could see the runway, but the color of the runway and the surrounding areas were basically the same. Without color difference, it was difficult for him to judge the altitude with the naked eye, and he could only rely on the avionics system.
He controlled the fighter plane to descend steadily, the speed brakes were raised, and the landing gear was all extended smoothly, maintaining the prescribed landing speed and approaching the runway.
Watching the runway getting bigger and bigger in front of him, he had an illusion for a moment. The runway seemed to be rushing towards him at a very fast speed. He quickly looked at the attitude data, and found that there was no change. He felt very calm. If he pulled the lever due to the illusion, it would be destroyed.
Fall into landing attitude.
Suddenly, Zhu Wei's shout came from the radio, "Li Hai pull up! Pull up quickly and go around! You are about to hit the ground!"
Li Hai pushed the throttle lever to the end like a conditioned reflex, and at the same time gently pulled the lever to retract the airbrake. At the current speed, if the control lever is jerked and the angle of attack is too large, the result will be a stall. Zhu Wei's erratic shouting showed that the situation was critical.
But Li Hai did not panic.
??????55.??????
The nose of the No. 583 J-15S was slightly raised, and the two newly modified engines instantly burst out with fiery tail flames, impacting the runway. The engine nozzles were only a few dozen centimeters away from the runway. If Li Hai did not handle it in time, the fighter jets would approach at a close range.
Hitting the runway at a speed of 300 kilometers per hour!
Li Hai successfully escaped and went around, and immediately knew something had happened - there was a problem with the aircraft. He quickly started the avionics system self-check.
At this time, Zhu Wei asked on the radio, "What's going on? Your altitude error is very large. Is there something wrong with the avionics system?"
Obviously, as an experienced pilot, Zhu Wei also thought of this.
Li Hai replied, "It's very possible that the system is self-checking. I'll clear the place and you can check the height."
After saying that, he immediately continued to turn and accelerated the landing route again. To be on the safe side, he set the altitude at 300 meters. Then, he flew the plane over the runway. The ground support personnel had already been prepared and quickly measured the
The flight altitude of No. 583 J-15S.
Zhu Wei got the data and immediately called Li Hai, "Li Hai, your altitude is 2145 meters."
"It's the altitude data that's wrong. It shows three hundred meters here," Li Hai replied.
Sure enough.
At this time, the self-test results also came out, and there was obviously no problem, which meant that there were many problems with the avionics system.
Knowing the error value, Li Hai landed quickly and drove the fighter directly into the maintenance hangar under ground guidance. The J-15S project team came by commuter bus and immediately conducted troubleshooting, and the maintenance staff took out the flight parameters.
, the follow-up troops and manufacturers will form a joint investigation team to investigate.
For a fighter aircraft that has not yet been finalized, it is normal for problems to arise, and everyone has already prepared a plan. In fact, everyone hopes that all problems will be exposed before the aircraft is finalized, not after it is commissioned into the army.
Zhu Wei organized everyone to review the flying ginseng, which was related to whether winter training could be carried out. Everyone from top to bottom paid great attention to it.
There is no problem with the flying simulator. Every control action by Li Hai is textbook-style, and dangers caused by human factors can be completely ruled out.
Li Hai said, "As we expected, the biggest difficulty is landing. The situation here is different from that in the Northeast. Even if you can't see landmarks in the Northeast, you can at least find some reference objects. We can see everything here.
Less than."
Decades ago, pilots mainly relied on ground radar guidance when flying. When landing, they had to find landmarks near the airport, such as a tall building, and use them as references to determine their position. In the past, in addition to ground radar guidance, pilots also had to follow the
Flying from the location of the navigation station is like an invisible road in the sky.
Today's aircraft are becoming more and more advanced, and the various navigation systems supporting the aircraft are becoming more and more complete. It is basically impossible for the aircraft to find the airport.
This is flying over land.
At sea, at hundreds of kilometers in the air, an aircraft carrier is as big as a pinky fingernail. The first thing carrier-based pilots have to solve is to find the aircraft carrier in the vast sea. Even with guidance, it is very difficult.
It can be seen that the special combat environment places higher requirements on carrier-based aircraft pilots.
Li Hai said, "Basically we can only rely on instruments to fly. However, no matter how advanced the avionics system is, it will be affected when encountering complex weather conditions. My opinion is that it is absolutely fine to conduct winter training. It will take more time to land."
That’s all.”
Others fully supported Lehi's sentiments.
Zhu Wei thought of Li Zhan's words, nodded, and made up his mind, "Okay, hand in the formation report, and as soon as Haisi approves it, we will start winter training immediately."
Everyone jumped for joy.
At this time, Li Hai said, "Team leader, the ejection take-off test is basically completed. Chief Engineer Fang Juemin said that the next step is to conduct an arrested landing test. Let's just do an arrested landing this winter training. Anyway, it takes a lot of time to land.
Blocky."
Luo Falcon frowned slightly and said, "The risk factor is a bit high."
"The runway is slippery in winter, which is good for blocked landing tests," Li Hai said.
Matched with the electromagnetic ejection system is a brand-new arrested landing system, and the two are integrated. Moreover, the arrested landing system also uses electricity, which is more than one generation more advanced than the hydraulic system currently in use.
The biggest advantage of the electromagnetic arresting landing system is that it is very small, which greatly saves the space of the mothership. It can carry more fuel and other supplies, and can carry more aircraft, which greatly improves its continuous combat capability.
Zhu Wei did not hesitate, thought for a moment, and said, "Okay, let's report this to our superiors."
Dang Weimin and others grinned.
Ordinary training subjects are no longer challenging for them, and the most important training content for the experimental training group is only two, one is ejection takeoff, and the other is arrested landing. Relatively speaking, the latter is much more difficult.
The aircraft carrier qualification assessment is based on whether it has the ability to land on the ship. After all, takeoff can be left to the engine and ejection system...()
