Feifei, writing the "Chinese answer" of the sea and sky —— On the way of independent training of talents from the group of Shipborne aircraft flight instructors in a base of Naval Aviation University ■ PLA Daily reporter Qian Xiaohu, Wei Bing, special reporter Sun Fei, correspondent Liu Renfeng In the Bohai Sea in late autumn, the Liaoning ship broke the waves. When the carrier aircraft enters the approach route, the "dancer on the tip of the knife" has to complete hundreds of actions in just a few tens of seconds. Four arresting lines span the wide deck, like "top peaks" waiting for landing. Dare to be the first in the world and dare to bite hard bones. In thousands of explorations and practices, the Chinese Navy's shipborne aircraft flight instructors have worked together to write a "Chinese answer" for the cultivation of Shipborne aircraft flight talents—— Life and death depend on each other and pursue excellence "Tie the same climbing rope, even if you pull, push or even lift it, you will climb over the peak together." "With a bang in my ear, the huge air flow immediately poured in, put me on the seat, and the plane shook violently..." At that moment, Liang Libin, the flight instructor, encountered special circumstances for the first time, which inevitably made him nervous. "But I must calm down quickly. There are still students in the cabin. At this time, if I panic, he will be even more panic..." On that day, Liang Libin was leading the student Qu Kun to carry out low altitude flight training in the valley. After a turn, the birds suddenly appeared above the fighter. They urgently adjusted the attitude of the plane to avoid it, and a lone bird hit the fighter head-on. With a bang, the cockpit cover was hit with a huge gap, and nearly 80% of the area was damaged. Liang Libin continuously and loudly reported to the tower commander. However, the sound of air flow overshadowed the sound of communication, and he could only receive the commander's instructions through the gestures of the wingman pilot. "Qu Kun and I tried to bend forward to reduce the airflow resistance as much as possible..." take the rod, close the throttle and slow down, and a series of operations were completed at one go. At this time, the height is only 160 meters. Below the wing is the residential area, surrounded by undulating peaks. The tower command was decisive, the wingman followed closely, and the students cooperated tacitly. Liang Libin kept the plane in state while constantly observing the outside, completed nearly 100 zero error maneuvers, and finally landed successfully. "At that time, I was very worried that Qu Kun would launch. If he did, I would be ejected..." recalling that at that time, Liang Libin was most pleased that the trust of life was entrusted between the students and the instructor. "The standard of piloting a carrier based aircraft is particularly strict. It can be said that it is the 'Mount Everest' of the flight industry. We and the students are just tied to the same climbing rope. Even if we pull, push or even lift it, we will climb that peak together." Sun Baosong, commander of a base of Naval Aviation University, said with deep feeling, "we can't easily give up anyone for the cause of aircraft carrier." Training shipborne aircraft pilots is a "glorious thorny road": new system, new field and new battlefield... In front of flight instructors, there are too many "empty" to fill in and too many "roads" to go. Only by stepping on difficulties, putting life and death aside, and working hard and willing to be a ladder, can we hold up the ladder of "dancers on the tip of the knife" to pursue dreams. One midnight, AI Qun, a flight instructor who claimed to master the "fast sleep method", lost sleep. As soon as he closed his eyes, a student hesitated to push the fuel door when he fell into the "black area", just like a thorn "pierced" Ai Qun's mind. Because of his low back injury, the student's modification progress lags behind that of the same batch of students, and his understanding of Shipborne flight is also lacking. AI Qun specially drew a refitting road map for him, so that his growth gradually entered the "fast lane". But this time, he encountered new problems. AI Qun suddenly sat up and decided to go to him and ask why. "As soon as the attack angle of the fighter is large, it always wants to hold the pole position and dare not push it out." Finding the root of the problem, AI Qun ran back to the dormitory, took out the plane model, simulated and explained it. AI Qun was relieved until the student nodded seriously. Influenced by the old instructors, young flight instructor Zhang Yuliang often stays up late to watch the flight videos of the students, analyze the flight curves, and pull them for one-on-one guidance and repeat each Sorty after the flight. Zhang Yuliang can be seen in the evaluation room, dormitory, restaurant and exit car. "I'd rather be tired than miss a key point." This is the professional habit that Zhang Yuliang gradually developed after he became a flight instructor. Before the "big test" of a new group of flight cadets, Zhang Yuliang set the place of class on the beach and gave everyone a new "landing class". He started from the knowledge of aircraft carriers, to the analysis of the marine environment, to his own landing story... More like a friend chatting. At the end of the lecture, Zhang Yuliang suddenly asked, "why did you successfully fly to the aircraft carrier?" Some people say that in order to live up to the great trust of the motherland, others say that for the dream of flying on the sea. "The aircraft carrier eats better. The small goal should be to fly to the aircraft carrier for a meal." After listening to Zhang Yuliang's "standard answer", the students were stunned, and the young laughter immediately rang through the beach. Scientific, efficient, precise and concise "Digitization is not only a change of 'a pen and a pile of paper', but also a future interpretation of the iron law of Shipborne flight" Under the "flying shark" logo on the roof of the flight Cadet dormitory, there are seven golden characters - "precision, discipline and zero tolerance", which is known as the iron law of Shipborne flight. The flight instructor has an analogy: "each action during the landing of the carrier aircraft is like a domino, linked and closely related." The spacing of each domino is measured by flight instructors after countless tests. At 4:30 p.m., the sunset will "card" above the island opposite the base on time. Under the beautiful scenery of the sunset, the roar of the aircraft gradually stops, and the evaluation room is a hot scene. With the support of technology, they integrate the concept of digital training into flight. "Like a pair of 'invisible wings', it helps' flying sharks' fly more scientifically, accurately and efficiently." Sun Baosong said. The high-speed carrier based aircraft and the aircraft carrier in flight, coupled with the complex and changeable sea conditions and air currents, it is by no means easy to achieve the perfect combination between the ship and aircraft. Behind every successful "rendezvous" between flying shark and arresting cable, they have strong support of huge data flow. Centering, angle keeping, cable hanging... The view of the sea and the aircraft carrier shuttles rapidly in front of the pilot of the carrier aircraft. With a strong visual impact, the carrier aircraft stops steadily on the aircraft carrier deck. This thrilling scene took place on a dozens of inch electronic screen. Next to the simulator, Zhang Yuehong, then director of the simulation training center, couldn't help sweating. In recent years, in order to ensure the real-time and accurate transmission of simulated flight data, his eyes have always switched back and forth between images and data, looking for "upgrade points" for the developed real-time evaluation system. Entering the office of Zhang Ming, director of the evaluation room, the reporter found "different" at a glance: there are two horizontal and vertical screens on his computer desk. The vertical screen is full of information data being simulated and deduced; On the horizontal screen, there are more than 10 data related topics. If you look closely, the "completion time limit" of each subject is accurate to a certain day. However, only a year ago, the system was still on paper. Facing the new subject of improving flight data processing ability, most officers and soldiers have no bottom in their hearts: "we have no equipment and no talents. What results can we make?" "If you don't find a way to break through, you will be trapped in the well forever." Tu Shuai, a young engineer, decided to knock on the door of technological innovation. They gave full play to the unique advantages of "grounding gas", determined the scheme, compiled the algorithm and wrote the code. After repeated verification, they finally successfully developed the flight real-time evaluation system. Using this system, the flight video processing speed is 10 times higher than the original. At the left end of the first arresting cable on the aircraft carrier deck is the LSO workstation. Looking up at the landing route of the fighter, this is the best position. After each flight, the trainees will get a score. This score is not given by LSO according to impression, but according to each data of students flying. Just like divers, every action has its standard and score from preparing for take-off to entering the water. Flight instructor Luo Hu Lidan still remembers that when they first served as LSO, they could only record the trainees' training with pen and paper through sight observation and memory tracing. Dense data not only leads to long generation cycle, but also easy to produce deviation, which is not conducive to pilots' timely correction in training. To this end, they drew thousands of kinds of data into flight curves, analyzed the coincidence point between aircraft attitude and image through the peaks and troughs on the curves, and finally gathered the huge data flow on the tablet computer in the hands of each instructor in today's LSO workstation, and a set of digital command scoring system was born. "Digitization is not only a change of 'a pen and a pile of paper', but also a future interpretation of the iron law of Shipborne flight." Flight instructor Wang Yong told reporters that they have also established a full-time and all-dimensional training quality monitoring system, set up a database for full-time objective evaluation, and accurately evaluate each action and approach of flight cadets, so as to better quantify flight ability and quickly find out and fill gaps. Under the protection of "invisible wings", groups of young "flying sharks" flying talents set sail from here and fly far away. Pass on the firewood and forge ahead "In line with people's call for the spirit of the times, people will resonate" In the southeast corner of the flight canteen, there is a small vegetable garden. When there is no flight mission, Cao Xianjian, a flight instructor, likes to dig the soil and grow vegetables. He is careful when to water, fertilize and trim. His ears roared. He felt that the flight instructor was like a farmer working in the blue sky, "facing the instrument and the sky above his head", breaking his heart for "every plant and tree". In the eyes of young flight cadets, Cao Xianjian is like a walking statue of a hero when wearing a flight suit—— On April 6, 2016, Cao Xianjian encountered a major danger during his flight training. Special circumstances disposal regulations: pilots can parachute immediately. At a critical juncture, Cao Xianjian tried his best to keep the fighter. He didn't pull the ejection handle on his seat until the last two seconds before the crash. Because of the insufficient height, the parachute was not fully opened, and he fell heavily to the sea, resulting in multiple burst fractures of the thoracic spine, lumbar spine, caudal vertebra and so on 21 days later, Zhang Chao piloted the fighter for land-based simulated landing flight, and the aircraft broke down. Similarly, in order to save the fighter, Zhang Chao made a heroic sacrifice... The haze shrouded the flight career of Shipborne aircraft. Hearing the news of the sacrifice of his comrades in arms, Cao Xianjian, lying in the hospital bed, burst into tears. Go around, go around! Shortly after the first operation, the wound was not fully healed. Cao Xianjian, who used six steel nails to fix the fractured lumbar spine, began hard recovery training on the hospital bed. But the doctor's preliminary diagnosis was cruel: the fall was so serious that according to their experience, go around was impossible. He Qing, an expert from the PLA General Hospital, still remembers Cao Xianjian's eyes at that time, "when communicating
