摘　　要：CAT Ⅲ自动着陆在恶劣天气进场着陆时具有较高的安全性和可靠性,对此类运行机载设备的研究具有重要的意义。本文首先从基本概念及原理出发介绍了进场着陆等级的划分、故障—性能下降和故障—工作两类自动着陆系统以及完成自动着陆的机载自动飞行系统及设备,然后指出决断高度DH和跑道视程RVR对CAT Ⅲ自动着陆机载设备的限制,最后介绍了机载自动着陆系统精度、性能、完好性及有效性四方面的适航性要求,只有通过了适航验证的飞机才可以运行CAT Ⅲ自动着陆。CAT Ⅲ operations can provide a high level of safety and reliability when approach and landing in low visibility conditions,the study of equipment requirements for such operations is of important significance.In this paper,at first the auto-landing category,the two types of automatic landing system,i.e.fail-passive and fail-operational automatic landing system,and airborne automatic flight system or equipment are described.Then the limitations of runway vision range（RVR） and decision height（DH） to airborne systems for CAT Ⅲautomatic landing are presented.Finally,the airworthiness requirements about accuracy,performance,integrity and availability of airborne system are discussed.The operator cannot perform CAT Ⅲ operations until the airplane obtains the airworthiness approval.
