This paper introduces the design of flight program guided by ground-based augmentation system in the precise approach section. Through the comparative analysis of GLS flight program and ILS flight program, the advantages and characteristics of GBAS flight program are clarified. The code and criterion of GLS flight program guided by approach are introduced, and GBAS flight program guided by GLS flight program is discussed. An example of optimization of flight procedures provides a series of suggestions for the use of GBAS flight procedures at airports.
