Risk assessment of instrument transition flight training

In order to improve safety of instrument flight training for student pilotsꎬ training procedure and a risk assessment method based on instrument flight rules and aviation operation control theory were proposedꎬ and a model algorithm based on airspace collision risk and route safety obstacle clearance was built. Thenꎬ a complete assessment process of instrument flight release was establishedꎬ risk evaluation process and index system for procedure implementation were determinedꎬ and instrument flight training was carried out according to route transportation flight mode. Finallyꎬ the algorithm was verified with classic training test of Red Deer Base in Canada as an example. The results show that this model algorithm based on collision risk and obstacle clearance can systematically analyze relative elements and realize quantitative risk assessment of training content in all sessions.
