The Application of Data Warehouse Technique to Flight Accident

The new forecast analysis method on the flight accident-rate and the flight incident-rate is discussed by using the forecast method based on grey control principle.

Summarizing investigations on several flight accidents of CRJ-200 and its former type,the Challenger,caused by aerodynamic stall,analyses QAR data of an accident happened in the course of taking off,and conduct an analysis focusing on their contributing factors,the characteristics seen after the accident,the way of how to identify the aerodynamic stall and of how to get rid of it.

Method The human factor accident/incident classification standard is developed on the basis of Reason's Model, combining with CAAC’s traditional classifying method, and applied to the classified statistical analysis for 361 flying incidents and 35 flight accidents of China civil aviation, which is induced by human factors and occurred from 1990 to 2001.

This research explored the intra-structure of job performance of the military aviators by the confirmatory factor analysis on the basis of theoretical analysis, interview and questionnaire surveying.

Aiming at a hard problem to crack for the forecast modeling for flight accident rates,the forecast model of flight accident rates is established by using of the LS-SVM method based on statistical learning theory.
