| Abstract: | In-depth analysis of the QAR(quick access recorder) data of Boeing 737-700 and identification of the influence factors on aircraft fuel flow were performed.The fuel flow model of the aircraft cruise was established using the analysis method of multielement linear regression and the fuel flow of the aircraft cruise was verified using the model.The assessment of accuracy of verification shows that the established model has better verification effect and provides the reference for improving the control efficie... |
