Second, actively promote the gradual opening of low-altitude airspace, promote the development of general aviation, and incorporate general aviation into the strategic construction of the national next-generation aviation system. According to the analysis of four American institutions, data show that general aviation will play a 65% role in the field of public services. Compared with commercial flights, general aviation is more prominent in cost control and efficiency. It is estimated that by 20 15, more than 20 million general aviation flights will account for 77% of the total aviation flights in the United States, most of which will come from small commercial or general aviation airports, but from the top 65438+. The annual output value of general aviation aircraft is nearly $20 billion, and the industry generated by economic activities exceeds $654.38+000 billion every year. In addition, general aviation activities play a very important role in community safety and medical assistance. The reason why American general aviation is so developed is that besides the comprehensive national economic strength and highly developed aviation industry, the policy of free flight in low-altitude airspace is an indispensable basic condition for the development and prosperity of general aviation. Without this basic condition, nothing can be said. However, the opening of low-altitude airspace can not completely copy the American model and method, because the national conditions of China and the United States are quite different, only in terms of geographical location and surrounding environment. The east and west of the United States are two oceans, the Atlantic Ocean and the Pacific Ocean. Canada is in the north and only a small part of it borders Mexico in the south. The geographical location and surrounding environment are relatively simple, while the geographical location and surrounding environment in China are much more complicated. Therefore, it is necessary to gradually open low-altitude airspace in a step-by-step and conditional manner according to the specific conditions of national security and national defense, geographical environment and economic development. Taking Xinjiang as an example, we can first choose places where the demand of general aviation users is strong, such as areas where agriculture and forestry are concentrated, tourist attractions, and relatively developed cities, and gradually open low-altitude airspace in stages to meet the needs of various general aviation users for free flight. At the same time, it is suggested that general aviation should be included in the strategic construction of the national next generation aviation system. Although general aviation has just started in China, we can directly adopt the latest international technology and innovative ideas to lay out the framework of China's general aviation development system, which means that although we started late, we can't lose any more in strategic planning and technology application.
Thirdly, GPS technology can be used technically, and the technical standard of China's satellite (Beidou) can be formulated quickly and the function of how to integrate with GPS can be realized, so as to finally realize the goal of arbitrary conversion between GPS and Beidou. GPS is a relatively mature navigation technology in America. Although it is mainly used for precise positioning and precise strike of military targets, its navigation accuracy has been higher than that of traditional ground navigation facilities after wide-area and local enhancement in civil use, and its greatest advantage lies in its precise guidance ability that is not limited by harsh natural conditions such as topography, ocean, mountains and deserts. The United States, Australia, Canada and Singapore have successfully implemented RNAV/RNP and ADS-B 7-8 B for 7-8 years, and achieved great success and operational experience. Prior to this, MITRA's laboratory and FAA's technology research and development center carried out a large number of applicability experiments for derivative products of ADS-B and RNP technology. It can be said with certainty that these derivative technologies will be used in practical operation soon and have great effects. We should fully learn from mature technologies and apply them to the next generation air transport construction in China, boldly and resolutely use GPS technology from the technical level, and at the same time moderately develop and retain DME/VOR navigation facilities on the ground as backup means of GPS navigation. At the same time, the most important thing is to speed up the research and formulation of technical specifications and standards for the use of China's satellite (Beidou), and research and develop functions such as the integration of 6 and GPS interfaces. Finally, the goal of arbitrary conversion between GPS and Beidou can be achieved, which can not only enjoy the application of advanced technology, but also avoid the risks brought by international disputes or technical blockade. Fourthly, adopt the new technology of China equipment to realize the localization of air traffic control equipment. At present, most communication, navigation, monitoring equipment and air traffic control automation systems in China are provided by foreign manufacturers. Air traffic control units only use and maintain equipment as users, and the core technology is in the hands of equipment suppliers, which poses a great challenge to the upgrading and sustainable development of air traffic control system equipment in China. In the field of traditional technology, we are indisputably behind, because aviation developed countries have accumulated technology for decades. It is difficult for us to catch up, just because the birth and application of new technical concepts bring us opportunities, because almost all experts in the field of new technologies are on the same starting line, even if there is a gap, it will not be too big, so that we can establish our own air traffic control equipment research and development center. Give full play to the independent research and development capability in the development and application of new technologies, and absorb and digest traditional technologies to form the equipment production capacity with independent intellectual property rights, so as to lay a solid foundation for the free upgrade and sustainable development of domestic traditional equipment in the future. We can learn from the concepts of American next-generation air transport system, European air and space integration, global collaborative planning, etc., actively construct the concept of China's next-generation air transport system and formulate relevant implementation plans, actively negotiate with international civil aviation, actively declare the concept and construction plan of China's next-generation air transport system to ICAO, and submit plans and task books such as China's technical use standards or interface integration with international standards. Our aviation industry has obviously lagged behind seven developed countries in the past decades, but we must not miss the opportunity in the application of new technologies and the strategic planning and construction of the next generation aviation system in the future. We should take the opportunity of building the next generation aviation system, strive to narrow the gap with the aviation developed countries, and even surpass the developed countries in some areas through innovative ideas and development, so as to truly realize the leap from a big civil aviation country to a powerful civil aviation country.
