The visual landing procedure of shipboard aircraft is an important part for shipboard aircraft landing and it has strict requirements for the flight route.Based on MBSE method,the realization of visual landing route in the flight management system of shipboard aircraft is studied.Through requirement capture and analysis,the requirement model is established.By studying the relative motion relationship between the carrier and the aircraft during visual landing,the method for calculating the parameters of the visual landing route is presented,and analysis is made to the influence of different factors on the parameters.The aircraft dynamic and kinematics models are established.Finally,the different visual landing routes obtained are inserted into the flight management system for carrying out whole-process tracking and simulation of the three-dimensional trajectory.
