With the deepening application of information technology and network technology in the field of civil avi-ation,the quantity and importance of field loadable software on civil aircraft have increased greatly,and the trans-mission mode of field loadable software has changed from physical transportation to transmission and storage through the network.While these changes bring convenience and efficiency,they also introduce cyber security risks,pla-cing new requirements on the field loadable software management for aircraft continuous airworthiness management.This paper summarizes the certification policies and technical standards related to filed loadable software network security,analyzes the requirements of field loadable software network security management for aircraft continuing airworthiness,and provides ideas for operators to implement filed loadable software network security management policies and build system of software protection.
