In order to solve the growing pressure of large aircraft flight safety,a safety monitoring and training system of large aircraft was designed.Without affecting the original aircraft system,the data of the aircraft was collected.Combining the wireless communication,visualization and data processing technology,the data was shared with the ground facilities in real-time.In this way,the real-time sharing safety monitoring mechanism for flight and ground crew was set up.Based on data analysis,flight training and equipment health management system was built up,so as to promote the safety of large aircraft flight,the informatization of training,the intelligent of equipment maintenance.
