Safe and efficient land-air communication is an important means to improve flight safety. It is necessary to comprehensively evaluate the functions, perfomace and system safety of the new intelligent system in order to use artificial intelligence technology to replace the function of flight crew. This paper designs the detailed operation process of the artificial intelligence flight communication system and the interoperation interface of the avionics system, and then develops the working principle and architecture of the artificial intelligence flight communication system, as well as the hardware implementation scheme and some pilot operational procedures. Based on the analysis of system safety and communication performance, it is concluded that the AI flight communicator is feasible and its performance is better than the original system.
