The cold wind is biting and the iron wings are flying. As night fell, several helicopters from a brigade of the 73rd Group Army took off in an emergency, and the navigation lights outlined an arc in the night sky. "War is neither hot nor cold in season, nor in day and night." The brigade leader said that they organized night practical flight training in a coherent manner around the key and difficult subjects of formation flight, special situation handling, ultra-low altitude flight, field field field takeoff and landing, and tempered the hard skills of officers and soldiers in flight with the help of complex environmental conditions. The direction is difficult to discern in the vast night sky. The pilot Chen Zhiyang relied on instruments and night vision equipment to determine the flight attitude and position, and steadily controlled the aircraft to enter the target airspace. "We are about to enter the" enemy "air defense warning range and lower the altitude." At the reminder of the rear cabin pilot, Chen Zhiyang piloted the fighter plane to rapidly lower the altitude, then skimmed the sea at low altitude, and used the "enemy" radar blind area to skillfully evade the search. After reaching the target, he quickly searched and locked the target and carried out a simulated attack. In the other training airspace, the pilot once operated the fighter to accurately correct the position, and the fighter landed steadily on the takeoff and landing platform of the field alternate. On the islands and reefs, the night is heavy. Zhang Jiaqi, the flight staff, told reporters that there was no tower command or ground guidance during the landing on the island and reef at night, which was difficult and risky, and it was a test for the pilot's driving skills and psychological quality. On the apron, the flight support personnel are preparing for the flight again. Jiang Long, a mechanic, just hit a flashlight and got under a fighter plane to carefully review the key parts. He said: "It is easy to have problems such as airborne equipment failure in severe cold conditions, and more rigorous and careful inspection is needed." The cold night sharpens its wings and flies to war. The leader of the brigade said that in recent years, the officers and soldiers of the whole brigade have highlighted the key and difficult courses in the process of in-depth promotion of practical military training, focusing on refinement, and the combat ability has been continuously improved in practice. Midnight, the training is coming to an end. The reporter saw on the scene that the pilot who stepped off the fighter plane went straight to the tactical seminar room and made a comprehensive summary based on his personal experience. They carefully read the flight parameters, watch the flight video repeatedly, study and improve the tactical tactics, and further consolidate the training effect. (Outlook New Era)
