The functions and characteristics of four kinds of traditional precise approach and landing systems are introduced in this paper. Based on summarizing the assistant landing information of INS, RA, BA, a new frame of integrated precise approach and landing mode is presented, which not only contains the traditional approach and landing modes, but also covers the enhanced approach and landing modes by collocating the modes. This new frame makes the manner of approach and landing more flexible and efficient and can obtain the continuous and reliable information of approach and landing.
