On March 7th, over an airport of Air Force Aviation, at 13: 59, Li Feng flew into No.4 airspace in a fighter plane of J-J 10, and began to practice joint tactical maneuvers. He practiced hard at an altitude of several thousand meters, and sometimes circled sideways with a small radius after a fight, and then quickly made a series of tactical maneuvers such as dive and pull-up. Just as he was absorbed in preparing for the tactical action of "suddenly and sharply turning up", the engine "down-turning signal light" suddenly flashed, and at the same time a warning signal came from the earphone, and then the symptoms disappeared. This instant phenomenon immediately aroused Li Feng's vigilance. Whether the flash in his head is a real signal or a virtual signal is somewhat contradictory. If it is a virtual signal, I have to complete this action; If it is really an alarm signal, the aircraft engine will stop at any time. At the moment, I am in airspace 4, far from the airport. My plane engine is a single engine. The plane has no power, and the consequences are unimaginable. Whether it is a real signal or a virtual signal, it should be treated as a real alarm signal. He immediately reported to the commander and asked to resign. Commander Wang asked about the situation, agreed to return to the scene, and promptly reminded to check the condition of the aircraft and not to descend quickly. In the air, Li Feng immediately stopped the tactical action, quickly checked the working condition of the aircraft engine according to the special handling preparations made at ordinary times, and aimed at the airport to return. During the whole return flight, he has been thinking about a question: what if the engine suddenly stops in the air? Once the aircraft engine really stops in the air, it is necessary to decide whether to land or parachute according to the altitude and speed at that time. On the ground, the chief flight commander also took emergency measures according to the real situation, quickly got in touch with local civil aviation, transferred civil aviation aircraft, dredged the air route, and provided conditions for the forced landing of the aircraft.
When the plane just arrived 6 kilometers away from the airport, the engine "turned down the signal light" flashed again, accompanied by another voice alarm signal. He immediately reported the situation to the commander.
14:08 13, there was only one puff of smoke coming from the cockpit when returning to the landing course for 20 or 30 kilometers, and the engine sound became smaller and the aircraft engine stopped in the air. At this time, the altitude of the aircraft was 1 100 m and the speed was about 500 km/h. After the head-up display of the airborne facility turned twice in front of Li Feng, all the data disappeared and a black screen appeared. In the cabin, the pilot can only see a red warning light, and there is nothing to rely on. The only thing Li Feng can use is communication equipment. At this time, he stabilized his mood and reported to the commander: "The engine stopped."
The commander asked, "What's your height?" No one answered.
The commander then asked, "What now? Prepare for skydiving. " Still no answer. At this moment, Li Feng's radio communication was interrupted for about 20 seconds. There is no data to rely on on on the plane. He relies on good weather, visual observation and his own understanding of airplanes. According to the celestial line, he judged that his flying height was about 1 100 meters. With a solid aviation theory foundation and previous experience, I calculated the time when my plane entered the third turn and the fourth turn. He knows in his heart that he is driving a domestic third-generation new fighter, with perfect starting facilities and automatic driving ability. If you drive forcibly at this time, it is not conducive to control, especially when the altitude of the plane is low, and it is meaningless to drive again. According to the relevant provisions of the training program, when the aircraft engine is parked in the air below 2000 meters, the pilot can abandon the aircraft and skydive. It's time for him to make his final choice. Is it a forced landing? Or abandon the plane and skydive?
At this time, Li Feng resolutely chose the air slide to land. He quickly adjusted the plane and it entered three turns.
The plane is turning. After the commander gave the order to "prepare for skydiving", he calmly replied, "Now shall I try again?"
The commander immediately gave the pilot great trust and support and replied, "OK, OK." At the same time, he reminded: "Right? You can put down the landing gear and you can land in the field. "
"Yes, yes. Let me see. " Li Feng still didn't panic.
The commander asked, "What is the height now?"
"There is no picture in the head-up display."
The commander reminded: "Now put down the landing gear. Check whether the landing gear is put in place. "
"The landing gear is down."
The commander prompted: "You can descend now. You can drop the height normally and click back. "
"That's right."
The commander reminded again: "Pay attention to the direction. Drop the height and step on speed brake. "
When the plane lost power, it made an empty landing, and the descending speed was very fast. In addition, the aircraft itself has 900 kilograms more fuel than before, which increases the danger, but this has not shaken the belief that Li Feng Fei will come back. A series of processes such as aircraft descending, landing and taxiing. After the nose landing gear was automatically retracted, Feng Li bowed his head and squatted down.
14: 00 15: 55, the plane landed smoothly in front of the t-cloth 100 meters and landed successfully. It took only 1 min 44 seconds from the occurrence of the special situation to the successful disposal.
The front landing gear was not locked because the engine was turned off and the hydraulic power was insufficient. When the plane taxies straight to 1400 meters, it will be automatically retracted. He grasped the plane firmly. He thought that there were still some comrades who had not landed in the air. When they were 500 meters away from the head of the runway, they slid to the right side of the runway and stopped the plane firmly. The plane was only slightly damaged. Li Feng, a heroic pilot, created a miracle in the flight history of this type of fighter with good psychological quality and skillful driving skills in the face of sudden special circumstances.
Air force experts believe that there are three technical problems that plague flight safety in modern flight: stall spiral, engine "parking" and out of control, of which engine "parking" is the most difficult fault to deal with. This time, Comrade Li Feng successfully saved the plane under the complicated circumstances that the engine "turned off", the attitude display disappeared and the atmospheric data display disappeared. This is indeed a pioneering work in the history of flight, which is rare in the history of world aviation and unique in China.
