Expert System of Search And Rescue Roads Prediction for GA Crash

Aiming at the status policy of GA SAR intelligent degree is not high, using the object-oriented language C# and 3D-GIS platform as the frontend development platform of the expert system of prediction for possible airline, using MySQL as a backstage supporter's database of the system, an expert system of prototype for aeronautical search and rescue operations be developed. Firstly, the overall structure is introduced. Then, knowledge base and inference engine of the system is introduced in detail. At last, the expert system is verified through simulated instance. It is proved that in the case of a large margin of rapid decline and no surveillance information two symptoms occurred, possible roads of the crash aircraft could be predicted by this system. It is verified that the prediction of possible roads by this expert system is available and it is relevant for exploration of GA SAR intelligent, and it is a new method for GA SAR in China.
