Abstract


Ground proximity warning system is used to prevent civil aviation controlled flight into terrain (CFIT) accident alarm system alarm threshold settings significantly affect the properties of the alarm , how to set the alarm threshold is the study of ground proximity warning system technology important issues. This paper studies the Ground Proximity Warning System (GPWS) alarm mode several basic working principle and its corresponding alarm curve , gives a performance index based alarm threshold design methods. This gives a state space of the complex based on performance threshold alarm system design method , the method includes using a pre -defined trajectory modeling uncertainty factor , alarm and no alarm balance between , in order to set given appropriate alarm thresholds . Established a random terrain statistical model aircraft trajectory model no alarm and alarm trajectory model ; then integrated the related models and other uncertainties that you want to set alarm thresholds for a series of simulations . In the fifth chapter, nearly to the alarm system mode type 1 and mode type 5 curve settings , for example, in the MATLAB environment for computer numerical simulation to study the alarm system using computer numerical simulation to get the alarm threshold method proves the text proposed the threshold of the design method . In order to better study proximity warning system operating characteristics , this paper also uses OpeGL in VC 6.0 environment to develop a ground proximity warning system working three-dimensional visual simulation .
