| 摘要: |
| FLS进近是提高进近感知能力、降低运营风险的有效手段，是先进大型客机飞行管理系统的核心功能之一。针对FLS高级进近引导技术，研究了虚拟波束生成、波束偏差和引导指令计算问题，提出了基于导航数据库信息的虚拟波束生成方法和基于空间几何关系的波束偏差计算方法。通过引入角度偏差和距离偏差设计引导律，得到飞行引导指令，设计仿真测试算例，对提出的波束偏差和引导指令计算算法进行验证。仿真结果表明，所提的FLS引导算法可以实现高精度的进近。 |

| Abstract: |
| 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. |
