In modern aircraft guidance system development and setting process, the precision simulation has become an indispensable important technical means. According to the concomitant system theory, this paper applies it to the accuracy assessment of the guidance tool error of an aircraft and obtains the covariance matrix of the landing bias. Experiments show that the simulation method can improve the simulation test efficiency and facilitate the extensive analysis of the performance of the guidance system.
