FLS approach is an effective means to improve approach perception and reduce operational risk, and it is one of the key functions of flight management system of advanced commercial aircraft. This paper studies the generating virtual beam, calculating beam deviation and guidance command in FLS advanced approach guidance technology, and proposes a method of generating virtual beam based on navigation database information and a method of calculating beam deviation based on spatial geometric relationship. The guidance law was constructed based on angle deviation and lateral distance between the actual path and FLS beam, and the simulation test examle was designed to verity the deviation and guidance command calculation algorithm. The simulation results show that the FLS guidance algorithm proposed in this paper can achieve high-accuracy approach guidance.
