RIPAccording to reports, the afternoon of March 31, the Chinese Air Force, a two-seat Su -27 crash in Shandong, the two pilots on the spot sacrifice. The preliminary analysis of the crash models should the Su-27UBK, and is mainly used to coach flight. Order from 1992 the first batch of Su-27, imports and its own production of the Su-27, Su-30, F -11 series of more than 300 aircraft. The Su-27 as the Air Force's first third-generation fighter made "‹"‹an important role in the construction of the air forces of China. But need to pay attention to, coach Model of China's long-term lack of heavy-duty three generations of machines, more than 300 aircraft heavy fighters basically all imported 40 the Su-27UBK combat / trainer in the training work. For a long time, China's domestic advanced trainer only basic FT-7, unable to cope with the more advanced training work of three generations of machines. After the advent of the two-seater F -10 in December 2003, breaking the dilemma, but Su-27 / -11 F series heavy-duty machine is still dependent on imports So-27UBK, trainer, and is mainly used in the multi-purpose domestic two-seat F-11BS combat is not dedicated coach model, and the number is still limited. In recent years, three generations and four generations of machines is too costly, with its seat trainer model-based development is more costly and therefore specifically designed for next-generation advanced trainer become a new trend. Such as South Korea's T-50 "Golden Eagle", Italy's M-346, Yak-130, Russia, China's L-15 "Falcon". Machine of this type of higher education, has simulated three generations of machines or even four generations of machines the ability of the flight characteristics, and has advanced fly-by-wire avionics system, can be basically completed most of the three generations of machines or even four generations of machines Advanced coaching courses. Higher machine stand-alone type of cost and relatively low cost flight, and therefore become an indispensable force in the future Air Force training. Since the introduction of the Su-27 series in China since the 1990s, a whole generation of pilots need to refit three generations of machines, very tense flight coaching job, a mere 40 the Su-27UBK trainer (we have 40 trainer it? true or false) are long-term overload After ten years the body has a serious aging. Therefore, the alternative of domestic new generation of Higher Education is imminent. At present, the domestic JL-9 "Eagle" Higher machine has Working at Heico Air Force, but the machine is a single light machine, and the performance does not fully meet the training needs of three generations of heavy machine. Really three generations of machines capable of simulating the twin L-15 "Falcon Higher machine is still in the final test. Only a large number of new Higher machine service, in order to truly let on a larger scale, the lower the cost of training a large number of three generations of pilots, and even four generations of pilots.
