Flight Training Manipulating Quality Evaluation For Final Approach Segment Based On SD Card Data

Flight training maneuvering quality evaluation is a key link in flight training,which can not only grasp the operation level of pilots at each training stage in time,but also find out the shortcomings of training course system and improve them in time.Therefore,the evaluation of pilots in flight training has become the focus of attention of various training institutions.In this paper,the evaluation of flight training maneuvering quality in the final approach phase of the private single-engine-land training course is taken as the research object.Based on the flight parameters(SD card data)recorded by airborne Garmin1000 integrated avionics system,three evaluation indexes are designed in combination with the FTE,and an objective evaluation method of flight maneuvering quality in the final approach segment based on SD card data is constructed.This paper focuses on the following aspects:(1)Data characteristics of airborne SD card.This paper introduces the composition and classification of flight parameters in airborne SD card,deeply analyzes the source and data quality characteristics of flight parameter data recorded by Garmin1000 integrated avionics system,and puts forward the identification and smooth processing of outliers and other abnormal data to improve the quality of flight parameters.(2)Design of recognition algorithm for final approach segment based on SD card data.According to the characteristics of flight parameters in the final approach segment,the recognition algorithm of the final approach segment is designed by combining the decision tree model.(3)Design of maneuvering quality evaluation index in final approach segment.In this paper,according to the flight technical error and the requirements of the teaching syllabus of traffic circuit subject,three indexes of lateral error,vertical error and speed deviation are put forward.After analysis,the absolute quantity is converted into relative quantity,forming the final evaluation index system:LFTE,HFTE and VFTE.(4)Establishment of maneuvering quality evaluation model in final approach segment.The weight of each evaluation index is calculated by the entropy method.Based on the requirements of the course syllabus of traffic circuit,various grading grades and thresholds are designed for the final approach segment,and finally an objective evaluation model is constructed.(5)Verification of the evaluation model of maneuvering quality in the final approach segment.The training data of some student pilot are selected for evaluation,which verifies the feasibility of the evaluation scheme.The maneuvering quality of the selected pilots in the final approach segment after the private single-engine-land training is counted,the students manipulate the characteristics of the skill growth curve are analyzed,some suggestions for improving course teaching are given.
