# Fuzzy Comprehensive Evaluation of Pilot Cadets' Flight Performance Based on G1 Method
## 5 Conclusions  
In this paper, an evaluation model of pilot cadets' flight performance in traffic pattern flight was established using the Delphi method, the G1 method, and the fuzzy comprehensive evaluation method. For the evaluation of pilot cadets' flight performance, a traffic pattern flight was selected as the flight subject for the evaluation of flight performance. Combined with the flight training manual and expert interviews with flight instructors, a total of 19 flight parameters were selected as evaluation indicators, forming a flight performance evaluation index system for pilot cadets. The weight of the evaluation indicators determined by the G1 method incorporates the judgments of numerous experts on the degree of impact of the indicators. The evaluation model established by the fuzzy comprehensive evaluation method avoids the errors in the evaluation results caused by the subjective factors of the instructors. Then, the flight data of pilot cadets were obtained through simulated flight training experiments. By inputting the flight data into the evaluation model, the flight performance evaluation results were calculated for each pilot caded. The results show the evaluation index system established in this paper accurately reflects the flight performance of the pilot cadets. The evaluation model based on the G1 method and the fuzzy comprehensive evaluation method established in this paper has consistent

evaluation results with expert results. Therefore, the evaluation model has good rationality, accuracy, and applicability in evaluating the performance of pilot cadets.  
The contribution of this study is to propose an evaluation model that assesses the flight performance of pilot cadets during their traffic pattern flight training. By using this evaluation model to assess their current level of flight proficiency, it could help them to identify weaknesses in their flight operations and provide scientific support for the development of personalized training plans. In addition, the evaluation of pilot cadets' flight performance will also help to promote safer and more sustainable civil aviation operations in the future.
