Chapter 517: Two Seconds in the Second Training Zone
The first time he easily hooked the second blocking line, and even the second and third times, it can be attributed to luck, and the same situation has not happened before. It wasn't a surprise, at most a slight frown raised - oh, this pilot is good, or- oh, this pilot is lucky.
But the fourth and fifth times also hooked the second line of blockage, and it can't be attributed to luck. A simple action can be easily performed by everyone according to the standard, but very few people can complete it a hundred times and a thousand times in a row according to the same standard.
By the sixth and seventh time left, no one wanted Li Zhan's achievements to fall short, and everyone's attention was on the No. 588 J-15 in the sky.
On the contrary, it was the party Li Zhan who was in the most relaxed mood.
Chen Fei: This kid once landed at a speed of more than 800 kilometers per hour!
No. 588 J-15 circled back again, preparing for the sixth simulated landing hook blocking cable.
At some point, a cloud appeared over the southeast sea, and it was not an ordinary cloud but a rotating cloud, and as the area of the swirling cloud slowly increased, it soon obscured the morning sun.
The latest meteorological report was presented to Shi Moying by the meteorologist as soon as possible, and Shi Moying immediately reminded Li Zhan: "Five-eighty-eight, there is a whirlwind in the southeast, the distance is 20 kilometers, the maximum wind force is 8, the moving direction is 320, and the speed is 15 kilometers, pay attention." ”
"Five-eight-eight received." Li Zhan quickly confirmed the situation, and the game would be affected by the cyclone in an hour and twenty minutes, but he only needed ten minutes to complete all the training, so there was no problem.
Li Zhan fine-tuned the landing parameters according to the adjustment instructions of the flight control tower, and the fighter plane slowly descended again, and the personnel of the flight control tower, deck landing management, and other posts were engrossed in staring at the attitude of the fighter. The non-commissioned officer at the tower who was responsible for confirming the landing gear repeatedly confirmed and reported, but he still did not let his guard down, and unless the fighter landed safely, it would not be considered a complete mission.
No. 588 J-15 is like an earthy yellow goose flapping its huge wings from mid-air and slowly landing on the ground, with its head slightly raised, slightly untouchable.
The tail hook hooked the second blocking cable with great precision, and the second simulated blocking cable was broken without any suspense, and the 588 J-15 once again gently touched the ground and pulled up and flew around, this time climbing faster.
"Sixth!" Shi Moying was excited, and hooked the second blocking rope for the sixth time, which had already surpassed most of the instructors.
Zhang Xueyang's ten landings only have about half of the chance of success and he can become an assistant instructor, in addition to his high level of military English, on the other hand, because the subject of landing is really, really very difficult, and it is very good to be able to do five or six times out of ten landings and hook the second blocking cable.
Shi Moying had nothing to scruple about, he called Li Zhan bluntly, "Five-eight-eight!" You're going to land in the second training area! If you can hook the second blocking line for the seventh time, you will set a record since the start of Flying Shark training! Li Zhan! Come on! ”
"Five-eight-eight understands." Li Zhan's tone was very calm.
Shi Moying thought that Li Zhan's mentality was a little drifting after two or three successes, but in fact, it was him who was unstable now, not Li Zhan.
Taking off and landing is never the work of one person, there are so-called studies that show that the success rate of landing without ground guidance is only about 50 percent, and the success rate of landing in places where there is neither ground guidance nor an unfamiliar environment, the success rate is only about 15 percent!
And that's still data for land-based aircraft!
Therefore, if Li Zhan completes the Grand Slam and sets a record for the first actual flight training of Flying Shark students, then it will not only be him who will be rewarded, but will include all the officers and soldiers from Shi Moying, the commander, to all the posts below. Maybe not everyone will have honors such as third-class merit awards and awards, but it is possible to write a heavy stroke on the resume "to ensure such and such an activity", which is honor and capital.
On the contrary, Li Zhan didn't have too strong feelings, isn't it just landing on the ship, and he will land on the aircraft carrier countless times in the future, if the success rate does not go up, he will have to return to the flight every once in a while, and the time and aviation fuel will be wasted in the take-off and landing link, then it will be a fart battle.
So he thinks it's a basic operation.
Of course, take-off and landing are basic operations, but the problem is that the two contents of gliding and jumping off and blocking the landing of ships are completely new and unfamiliar to our military, and they are extremely difficult subjects of "carving Chinese paintings on rice grains."
The seventh landing drill was immediately conducted.
The weatherman suddenly reported: "Commander! The temperature is rising in the mountains of the north! There was convection 10 kilometers northwest of the runway, and a small cyclone was formed under the influence of the mountain! Report complete! ”
Shi Moying's attention was not entirely on the 588 J-15, he would look at the weather vane near the flight simulator deck from time to time, and at the same time pay attention to the temperature change table representing the nearby areas in several directions of the field.
The Fertile Ground Flight Training Base is basically backed by the mountains and faces the sea, but it is usually more than 30 kilometers away from the mountains at an altitude of several hundred meters, so it will not affect the take-off and landing of this field. However, because of the special shape of the mountainous terrain and the perennial southeast ocean monsoon, there are often cyclones in the mountainous areas, and those cyclones are usually very small, and the impact range is only two or three kilometers, characterized by extremely strong winds at low altitudes, tenacious vitality, and usually run out of the mountains or the edge of the mountains. This small low-altitude cyclone, which is very difficult to detect, is a very deadly danger to aircraft taking off and landing.
In many cases, it can even be compared to the power of a microburst.
Therefore, whether it is a fertile ground flight training base or an air force station more than 10 kilometers away, they attach great importance to the monitoring of low air currents, give feedback as soon as there is a change, and at the same time adjust the ongoing aviation training activities.
The distance of ten kilometers is not too far and not too close, and if the speed is fast, it will take three or two minutes to reach the field, but the low-altitude small cyclone running ten kilometers generally does not have much impact.
But there is definitely a big threat to the aircraft that is landing.
Shi Moying reported the situation to Li Zhan as soon as possible, but Li Zhan, who was making a U-turn in the southeast sea, said that he understood.
Of course, it's not that you come here to learn and consolidate your theoretical knowledge, and you will be put on the actual machine for a few hours, and you must have a good idea of the terrain, environment, weather conditions, and even customs. Pilots pay the most attention to the weather, which naturally goes without saying, sometimes whether you can eat this bowl of rice depends on whether God gives you face, if God gives you a 12-level typhoon, you can only fly higher.
Therefore, Li Zhan is very concerned about the small whirlwinds that often occur in the local area and the area where the site is located. It doesn't matter if the whirlwind is at high altitude, it just flies over at speed after a while, but the plane that is landing is only a few tens or even more than ten meters from the ground, and suddenly a whirlwind comes over and basically has a red pull ring (catapult switch) at the crotch position.
Li Zhan didn't dare to take it lightly, he completed his U-turn, the nose of the plane was aimed at the "aircraft carrier", and asked the flight control tower, "Tower, is there a condition?" Ready to join the standard glide line, done. ”
"Five-eight-eight can land on the ship, pay attention to the ship's signalman, over." After Shi Moying quickly confirmed that the small cyclone in the north had no effect on the airflow in the field, he allowed Li Zhan's landing request, and at the same time asked you to pay attention to the signalman of the ship.
If there is an unexpected situation, the landing signalman will notify the pilot to pull up the go-around as soon as possible.
"Five-eight-eight understands."
Li Zhan glanced sideways slightly, and one of the landing signalmen in a white vest at the landing signal post on the left side of the landing runway on the deck was ready. If something unexpected happens or he doesn't hook any of the blocking cables, the landing signalman will tell him to pull up the go-around within a second.
This time it's for real.
So at this time, Li Zhan was going to land in another "simulated aircraft carrier flight deck training area", that is, the second training area located at the north end of the runway. The first training area, which is almost 100 percent simulated, is at the south end of the runway, which is also the training site where Li Zhan has just trained, and the second training area does not have a sliding jump take-off deck, which is generally only used for landing training, which really blocks the landing of ships, so the second training area is a higher-order training ground in the eyes of the students.
According to the regulations, if the trainees have completed the first six simulated landings in a row and all of them have full marks, they can come to the second training area for the seventh time to stop the landing of the ship with real knives and guns!
This is also the reason why Shi Moying couldn't help but excitedly tell Li Zhan to land in the second training area just now, so far no student has won the qualification to land in the second training area for the first time.
The runway of the Fertile Ground Flight Training Base is 3,200 meters, which is the longest runway in the naval airfield, and the two training areas are deployed one in the south and one in the north, and there is a runway in the middle that is sufficient for taking off and landing any type of aircraft in service. But compared to the first training area, the second training area is very cold.
To put it bluntly, the first training area is built in a one-to-one ratio by simulating the flight deck and ship building of the aircraft carrier, which is a land aircraft carrier, so the relevant supporting facilities are all complete, even including some parts below the flight deck, such as the place to support personnel, and even elevators......
The second training area has nothing else except for a landing area, and the genuine arresting cable system is the most obvious sign of the training area, including the position of the landing signalman on the left side of the landing runway, which is also deployed in strict accordance with the position and proportion of the aircraft carrier.
That's pretty exciting.
Li Zhan swept over the first training area at a low altitude and maneuvered the fighter plane to continue to land along the standard glide line, and the instrument display data was completely correct. The tower signalman and the landing signalman told him one after the other that the landing gear was confirmed to be lowered, and the last worry was dispelled. Without a normal landing gear, it is useless to hook ten arresting cables.
"Five-eight-eight, the glide angle is raised twice."
The landing signalman immediately reminded him when he found the problem, and then was stunned to find that before he finished speaking, he found that the 588 had been raised by two degrees, which means that the pilot discovered the error earlier than him and immediately corrected the maneuver.
yes, the pilot himself has no sense of existence!
Li Zhan still replied, "Understand, raise it twice, raise it twice." ”
He sensed a more powerful downwind, causing the plane's glide line to run down, and he quickly calculated that it would need to be raised two degrees to return to the standard glide line, and the landing signalman gave the same instructions as he made the move.
This means that Li Zhan is easy to handle.
To be fair, a heavy fighter like the J-15 is not coincidental when it lands, it is like driving a sedan in reverse and a truck in reversing into storage, even if the acceleration of this truck is better than that of many cars. Li Zhan has rich experience in the use of J-11 family fighters, especially for the J-11A that still uses the same flight control system as the J-15, he is very clear about the feedback speed and control margin of this flight control system.
For example, if the J-10 series fighters are such as new sedans that use fly-by-wire transmission systems, then J-11A and J-15 are cars that use traditional transmission systems, the former theoretically rotates the steering wheel as many degrees as the steering wheel rotates, and the latter's steering wheel rotation degree and steering wheel rotation degree are different, such as the steering wheel rotates ninety degrees after one and a half turns.
Therefore, in order to accurately control a fighter like J-11A, it is necessary to have a very familiar grasp of the range and angle of movement of multiple flight control systems and joysticks, and to accumulate a lot of flight training time.
The old driver does not look at the wheel, and the novice reverses and stares at the steering wheel for several laps.
"Five-eight-eight keep a good posture, the action is very standard, it's over!" The landing signalman reminded Li Zhan and was in a surging mood at the same time.
Obviously, the record since the start of the training of the Flying Shark is going to be born, and it is under my guidance.
At this time, Li Zhan, who had already entered within one kilometer of the ship area, saw a small tornado visible to the naked eye at the end of the runway, the kind of tornado with a height of only twenty or thirty meters and a thin diameter was actually nothing, and even a few children were chasing and running, constantly grabbing the fallen leaves on the ground and raising them, and then watching the fallen leaves being swept up and laughing.
The tower will certainly not be visible, and neither will the landing signalman.
This small tornado is hardly destructive, but it can be a lethal to a landing warplane. More critically, a small tornado in the farmland not far from the end of the runway indicates that the airflow is changing rapidly, especially the low air current.
After Li Zhan landed, the second J-15 would take off for training, and one after another continued training.
Li Zhan, who would land within ten seconds, decisively freed up some of his energy to report to the flight control tower: "Tower! There is a tornado on the farmland at the north end of the runway, with a height of about 20 meters, and the low air flow is very likely to change rapidly. ”
This report made Shi Moying, who was paying close attention to his landing action, stunned suddenly, and quickly looked at the weatherman, but the meteorian shook his head and said, "There is no obvious change in the monitoring data!" ”
Shi Moying said decisively, "Five-eight-eight, you landed according to the plan, it's over!" ”
"Understood!"
Li Zhan did not hesitate at all, easily hooked the second blocking cable, the rear landing gear of the fighter touched the ground at the same time, pressed the nose to let the front landing gear hit the ground and stepped on the brakes, and at the same time the blocking cable system worked, exerting a strong resistance to drag the more than ten tons of fighter alive, the No. 588 J-15 of the 240 highway per hour was converted into a stationary state in just two seconds, Li Zhan pounced forward under the action of strong inertia, and his face was about to hit the instrument panel, but the seat belt pulled him alive.
The whole process is completed in less than two seconds.
Just after he stopped completely, the fighter plane suddenly swayed a few times, and a strong gust of wind blew, and Li Zhan suddenly broke out in a cold sweat. Being able to blow the fighter plane parked on the ground a few times can be seen to be a relatively strong crosswind, and if it had been encountered two seconds earlier, he would have ejected it at this time.
He immediately reported the situation to the flight control tower.
Shi Moying decisively ordered the suspension of training and ordered the weather monitoring department to quickly figure out the situation, and at this time, Lao Chen Tou had already gone out with a telescope and climbed to the top floor of the ship's building to the north of the runway to observe.
