Based On The D.S Evidence Theory Of The Evaluation Of Civil Aircraft Flight Safety Quality

The safety of the civil aircraft is important to the wealthy of country and the passenger life. Therefore, it is important to evaluate the flight safety quality.With the appliance of new technology, the safety and reliance of the aircraft is advanced. But rarely studied from the point of view of maintenance and repair of aircraft flight safety. Therefore, based the task cards refinement maintenance indicators, and MMEL minimum equipment list and other technical information support, combined with the information fusion technology, aircraft safety and quality assessment has important engineering significance.This paper introduced the concept of information fusion technology and aircraft line maintenance work. Based on the routes task cards, MMEL minimum clearance equipment list and related technical manual, index extraction, established evaluation index system. By the D.S evidence theory, to fusion the information and to achieve the final aircraft flight safety quality key.
