A detailed comparison and analysis of guidance schemes for aircraft ascent phase in foreign countries is made. It is pointed out that the guidance algorithm with real-time updating capability is the development trend of future guidance system. Aiming at the guidance error caused by the high uncertainty of aircraft model, Advanced guidance methods, given its implementation process, the related difficulties and the corresponding solutions, the establishment of the aircraft ascending section simulation model. The simulation results show that the advanced guidance method based on fast trajectory optimization can significantly improve the flight quality of the aircraft, and the algorithm runs efficiently and reliably.
