"At present, China has the economic strength and scientific and technological strength to develop helicopters. There is a demand for helicopters in public security, maritime rescue, fire fighting and other industries. Now the country needs to pay attention to the helicopter industry and formulate a strategic development plan for this industry. " Wang Bin, deputy chief engineer of China Aviation Industry Corporation II and chairman of Chang Fei Group, said. It is time to vigorously develop the government helicopter aviation service team. At present, many departments in China are building their own helicopters, which need a series of work from logistics to maintenance. After the establishment of a special government aviation service team, other departments can purchase services from the aviation service team, which can reduce costs and avoid repeated construction.

Li Daguang, a professor at National Defense University, said in an interview with the Global Times: "The maintenance conditions of this helicopter are relatively low, with a speed of 200 kilometers per hour. It is an air first aid courier with unparalleled advantages. " Militarily, an American airborne division has 120 helicopters, and the Japanese Self-Defense Force also has hundreds of helicopters. In this earthquake relief activity, foreign-made helicopters became the main force, mainly because the highest altitude in some places in the disaster area can reach 4200 meters, while some domestic helicopters can't reach this height. China needs to develop helicopters, especially those with large transport capacity, heavy load and multi-purpose. Li Daguang said: "China is organizing forces to develop large aircraft, which is a strategic decision. Since it has the ability to develop large aircraft, China also has the ability to develop helicopters. "

Large helicopter supplementary first aid

China, with a vast territory and a large population, is one of the countries with the most natural disasters and the most serious losses in the world. The dispersion of disasters in time and region has brought great difficulties to emergency rescue, which has become the main restrictive factor affecting China's economic development and social stability. In the process of dealing with all kinds of emergencies, aviation emergency rescue has the advantages of being fast, efficient and less limited by geographical space. It is the most effective emergency rescue method widely used in many countries in the world, and helicopter is its core equipment. In China, civil helicopters are mainly small and medium-sized, while plateau and heavy helicopters are almost blank, and there are not many high-performance large and medium-sized helicopters. The development of helicopters, especially large helicopters, is the crystallization of China aviation industry.

AC3 13, as the first large transport helicopter developed in China in full compliance with airworthiness regulations, has a maximum takeoff weight of 13.8 tons, is suitable for all kinds of complex and harsh environments including marine climatic conditions, can take off and land in general aviation and paramilitary fields, and can perform tasks such as personnel, material transportation and search and rescue, emergency rescue or cargo transportation, forest fire prevention, medical rescue, search and rescue, offshore oil and so on. A3 13 successfully made its first flight, which kicked off the national emergency rescue system for domestic helicopters.
