Abstract


Highland terrain of western China is complex, more the highland route and altitude airports , relatively harsh operating environment , a higher risk of aviation operations , the altitude flight emergency rescue in particular , need to pay close attention and study . This paper analyzed the current situation of the domestic and international emergency rescue , combined with the the plateau specific environmental and geomorphological analysis of actual constituted by emergency rescue , implementation , analysis of the external factors that affect the impact of high altitude flight emergency rescue sub-factors and establish model ; combined with analytic hierarchy process and expert system of assessing the impact of high altitude flight emergency rescue factors ; application on the basis of the theory of fuzzy mathematics assessment of the current emergency rescue trend , the use of neural networks to conduct a comprehensive assessment of the current emergency relief trend ; digital elevation model plateau flying search and rescue map . The main conclusions are as follows : 1 factor is the priority in the process of search and rescue search plan and evaluate search technology and operations , communications , emergency coordination center , and search and rescue equipment , the above factors to focus on construction and control . 2 Posture Review , fuzzy math theory into membership vector from a single interval , the current emergency rescue situation more objectively reaction . Neural network assessment organic trend of membership and the total score to unify with the systematic and scientific , can be used as an effective tool for high altitude flight emergency rescue situation assessment and also to improve the high altitude flight emergency rescue to provide basis for decision making . 4 digital elevation model based on accurate terrain features extraction, ridge lines , valley lines and terrain block properly obtained is a to determine distress regional and formulate the basis of the search route . These research results can be expected to have a certain reference value for high altitude flight emergency rescue , hopes to reduce aviation distress losses , and increase the probability of success of the probability of survival and emergency search and rescue .
