Why not send a plane directly to Wenchuan for disaster relief?

The aftermath of the earthquake will lead to the failure of the aircraft electronic system and the inability to navigate. Secondly, Wenchuan is a mountainous area and there is no place for helicopters to land. With the roar of the motor, a remote sensing plane took off from Guanghan Airport in Sichuan and flew to Wenchuan. Zhang of the Aviation Remote Sensing Center of the Chinese Academy of Sciences can't remember how many times this flight was in Wenchuan, because after the Wenchuan earthquake in 2008, his team conducted remote sensing flight monitoring here for five consecutive years. On the 0/0 anniversary of Wenchuan earthquake/KLOC-0, they came here again for telemetry. The telemetry results are satisfactory. On May 8, the pilot project of "Earth Big Data Science Project" released information: the landslides of five large landslide groups in Wenchuan disaster area are in good condition; In old Beichuan, Hanwang and other towns 12, the overall intensity of landslide activity shows a downward trend, but the landslide and debris flow disaster and its danger still exist in the earthquake area; The danger of dammed lake in Wenchuan earthquake zone has been basically eliminated, and the largest dammed lake in Tangjiashan has become a scenic spot and an important water conservancy facility. 1986, China established an aerial remote sensing center with "Zheng S/II" high-altitude remote sensing aircraft as the loading platform, which played an important role in the national resource and environment investigation and flood disaster monitoring. However, for remote sensing people, the 2008 Wenchuan earthquake became a turning point in remote sensing emergency monitoring. It is in the earthquake relief that the aerial remote sensing personnel of the Chinese Academy of Sciences serve for disaster relief, upgrade their technology, and strive to participate in the establishment and improvement of a new disaster emergency mechanism in China. Zhang recalled that before flying to Wenchuan, there was no advanced digital aerial camera in Aviation Medicine Center at that time, only film camera, and the post-processing of film was very slow. Then, I contacted and seconded an ADS40 digital aerial camera. Relying on the high-resolution data of the earthquake zone, researchers reported more than 100 reports to the country through scientific analysis, and shared the data with more than a dozen national ministries and commissions. After Wenchuan emergency relief, a new remote sensing emergency mechanism was initially established. After that, Yushu earthquake in Qinghai and Lushan earthquake in Ya 'an struck, and remote sensing people put themselves into disaster relief work more quickly and effectively. During the Wenchuan earthquake, remote sensing people still went to the air traffic control department to apply for flight with various certificates and procedures. "Later, the comrades in the air traffic control department told me that in case of such an emergency, you don't have to run, just make a phone call." Zhang was very moved when he remembered it. The remote sensing data after the Wenchuan earthquake were taken off the remote sensing plane and immediately sent to Chongqing Jiangbei Airport, and then taken to Beijing by Air China flight. As soon as the plane landed, the comrades who took the data rushed to the institute with hard disks and began to analyze and judge the data. When the 20 10 Yushu earthquake occurred in Qinghai, the Earth Observation and Digital Earth Center of Chinese Academy of Sciences, together with the Network Information Center of Chinese Academy of Sciences and Chengdu Branch, opened a dedicated channel for optical fiber transmission data, which achieved remarkable results. After the Yushu earthquake occurred on April 14, the remote sensing plane of Chinese Academy of Sciences rushed to the disaster area at the first time and sent the data back to Beijing for processing in time with optical fiber. For the first time in the history of China earthquake disaster, the flight of the Space Center realized the aerial remote sensing monitoring on the day of the disaster. Now the Chinese Academy of Sciences has invested more support in aerial remote sensing. At present, the Space Center has built the most advanced high-altitude remote sensing scientific platform with all-band comprehensive observation capability, and has a full set of optical and microwave remote sensors.
