In order to improve the reliability and safety of embedded software for military airborne equipments,the introduc⁃tion of an airworthiness concept into military aircraft development is firstly proposed based on summarizing the experience get⁃ting in major aircraft development. Proceeding from the conception and connotation of airworthiness,many practices for the air⁃worthiness management of embedded software in military airborne equipments were executed in the aspects of DO⁃178B,soft⁃ware engineering management,software design and implementation,as well as software verification. It is proved that,with the airworthiness management of military airborne embedded software and innovation,the quality and safety of military airborne em⁃bedded software were promoted,and the malfunction ratio in flight was reduced for sure.% 为了提高军用机载设备嵌入式软件的可靠性和安全性，在总结重点型号研制经验的基础上，首次提出了在军机研制中引入适航理念，开展适航工作。通过从适航概念与内涵入手，从软件适航性DO⁃178B、软件工程化管理、软件设计与实现、软件验证等方面一一进行了军用机载设备嵌入式软件适航管理的实践。实践证明，军机嵌入式软件在技术上和管理上充分借鉴适航，大胆创新，确实推动了军机软件研制质量与安全水平的不断提高，飞行故障率大大降低。
