| Flight training is an important process in the training of airline transport pilots,an indispensable link to ensure flight safety,and a solid foundation for improving the basic pilot skills of pilots.Objectively and accurately evaluating the flight level of pilot students plays a vital role in ensuring the quality of training,and is also the desired goal of each flight training center.In order to solve the subjective shortcomings of traditional flight training quality evaluation methods,it is necessary to establish a set of quantitative evaluation methods based on data,through which the training quality can be objectively evaluated.The purpose of this thesis is to establish a modeling method for teardrop pattern subject based on flight parameter data.And determine the FTE(flight technical error)-based teardrop pattern subject handling quality evaluation model,which is used to evaluate the training quality of students’ flight teardrop pattern subjects.It can be roughly divided into the following aspects:(1)Nominal track modeling of teardrop pattern subject.According to the flight parameter data recorded by SD card and the basic data of teardrop pattern subject,the space cartesian coordinate system is established,the conversion method between latitude and longitude coordinates and space cartesian coordinates is determined,the flight segment of teardrop pattern subject is divided,and the mathematical model of nominal flight path is constructed.(2)Calculation method of flight technical error(FTE).The calculation method of flight technical errors(HFTE,LFTE and VFTE)in straight and turning segments of the teardrop pattern subject was developed,and the 95% confidence probability of flight technical errors in each segment was selected as the evaluation index of the control quality of the trainees in this segment.(3)A FTE-based assessment model of teardrop pattern subject manipulation quality was established.According to the 95% confidence probability value of flight technical error of each flight segment,the weight coefficients of different evaluation indexes on each flight segment were determined by using expert evaluation method and improved sequence relation method(method).Based on the requirements of teaching syllabus and practical examination standards of teardrop pattern subject,the evaluation model of manipulation quality of the whole teardrop pattern subject was constructed.(4)Verify the evaluation model of manipulation quality of teardrop pattern subject.The SD card data of teardrop pattern subject in the instrument training practice examination of flight cadets are selected and the evaluation model constructed are used to grade the manipulation quality.And compared with the examiners’ scoring data of the corresponding subject to verify the validity of the constructed evaluation model,and conducted a statistical analysis of the flight manipulation quality of the selected flight cadets in the examination of the teardrop pattern subject. |
