Large airports should pay close attention to the application of LED lighting in large international airports and the research and development trend of navigation aids, establish working links between airports and airports, and between lighting manufacturers to achieve information technology sharing. The airport navigational lighting system is an important reference for aircraft landing and ground taxiing. In recent years, with the advent of LED navigation aids, it is a major improvement in the navigation technology. At the beginning of the market, it is difficult to promote in the civil aviation industry because of its high price. With the maturity of technology and the improvement of technology, the price gap between LED lamps and traditional lamps is gradually narrowing, and its operational stability, light source life, color, The advantages of uniformity of illumination and energy saving are obvious, which brings convenience to the promotion of LED navigation aids in the airport. According to the statistics of 2017, the number of passengers in domestic airports reaching more than 10 million has reached 32. Taking the capital airport where the author is located as an example, the flight is still growing every year, and the aircraft model is also developing in a large-scale direction. In the context of airlines lining up to enter the capital airport, the contradiction between aircraft operations and ground facilities maintenance has become increasingly apparent. Therefore, the stability of the ground facilities has been reached within the airport. This year, on the basis of adhering to the flight safety bottom line, the Civil Aviation Administration has put forward a high-quality development concept, and has put forward higher guarantee requirements for the operation and management of the airport. The safety of the runway is the top priority. In this context, the runway operation is guaranteed. Safety, shifting the focus of work to the maintenance of the runway facilities, reached a consensus within the airport, and because of its low failure rate, LED lamps have become the best to reduce the workload of maintenance personnel, improve the operational stability of the navigation lighting system, and shift the focus of work. select. The advantages of LED lamps are so many, but their application status in China is not optimistic. The reason is that the development trend of dimmers and isolation transformers matched with LED lamps is lagging behind. The existing facilities and lamps are not well matched. Good effect, need to invest a certain cost to upgrade; second, LED lamp repair is more technical than traditional lamps, technology is mastered in the lamp manufacturer, existing maintenance has technical threshold; third, there is still a gap between LED lamps and traditional lamps, out of the The sensitivity of the price cannot be applied in a large area. Fourth, the flight volume of the domestic airports has not reached the order of the capital airport. The contradiction between maintenance and operation is not as prominent as that of the Capital Airport. Another problem that cannot be ignored is that there are more snowfall or low visibility weather in the northern airport. The LED lamps have better penetration than the traditional lamps under their own heat and low visibility. The snow melting ability of the LED lamps in the snow conditions of the northern airport. It is still necessary to observe that in terms of penetrating power, even in the field of civil lighting with a slightly lower safety margin, such as automotive lighting, there are few lighting headlights to install LED light sources, further illustrating the concerns of this issue. Moreover, due to its long life cycle, LED lamps do not have a comprehensive data statistics on the attenuation of light intensity (in the industry, the light source is attenuated to 50% of the specified value as the failure standard), and tracking verification is still needed. For taxiway navigation aids, the above problems can be neglected due to lower light intensity standards, and runway luminaires have certain difficulties due to higher visual requirements. In summary, as for the Capital Airport, as the leader of the domestic airport industry, we should adhere to the concept of leading the development of the industry, comprehensively evaluate the promotion prospects of LED lamps and the impact on existing maintenance work, and actively promote the application of LED lamps in airports. . Secondly, relying on statistical data, LED lamps have been initially verified in the operation of the Capital Airport (the Capital Airport installed more than 200 sets of LED slides on the taxiway in the Eastern District in 2014, and the test situation is good), mastering the diversity of LED lighting brands and The difference in technology, as well as the connection with the original navigational lighting circuit after a wide range of applications, to achieve a smooth transition, cooperate with the Bureau to issue industry guidance, verify the use of low temperature conditions in winter, become the next step for the airport side Work carried out. Thirdly, the application of LED navigation aids in the airport should be carried out step by step. In the initial stage, it can be installed in areas where the difficulty of stopping the navigation and the relative failure of the lamps, such as rapid departure from the taxiway area, and then gradually promoted throughout the venue, and should be done well. The following aspects work: First, carefully sort out the regulations and standards for the application of LED lamps, purchase and install according to regulations, to ensure that the requirements of the Bureau are met; second, clarify the details of maintenance and inspection of LED lamps, speed up the training of maintenance personnel, and improve the disposal capacity. The third is to increase the promotion of new lamps and new scientific research projects in this field, coordinate the bureau and lighting manufacturers to evaluate the application prospects of new lamps and technologies in the airport, and explore effective ways to improve the safe and stable operation of the airport navigation lighting system; It is actively promoting the construction of the navigational lighting laboratory, which is in line with the promotion of new facilities and technologies, and creates good prerequisites for its application at the airport. Finally, large airports should pay close attention to the application of LED lamps in large international airports and the development of navigation aids. Trends, establishing working relationships between airports and airports and between lighting manufacturers (
