Research on the Operational Safety Evaluation of a Type of Aircraft Based on Entropy Value Method.

In order to study the safety condition of aviation operation, the entropy value method is applied to evaluate the safety operation of an aircraft type. Based on the event type, number of events, event level and flight time, a risk-value safety evaluation index system was established, and the safety situation in the past years was calculated by the entropy method. The results show that the evaluation results are basically consistent with the actual operation of a certain type of aircraft, indicating that the safety evaluation method based on the entropy value method is applicable to aviation operation safety evaluation.
