As a landing mode of fixed wing aircraft，visual landing will exist for a long time.Based on the visual landing principle，the internal mechanism of the light array optical landing aid system is analyzed，and the light array arrangement scheme is analyzed considering the aircraft landing characteristics，aircraft carrier characteristics and the influence of other factors.According to the landing glide path geometry，the visual landing point position correction algorithm under two kinds of stable modes is proposed，and the light array unit control logic is optimized to improve the landing guidance accuracy.Finally，the designed light array optical landing aid system is simulated and verified by experiments.The result shows that the system realizes the unity of pilot's line of sight in “watching lights” and “centering”，and can meet the requirements of guidance accuracy and landing safety，which is an important research direction of visual landing guidance method.
