As the development of advanced civil aircraft cockpit, multiple displays shall coordinate with each other, rather than performing independently, which can interact with crews. This mutually redundancy of displays ensures robustness of display systems, increasing system availability. Further, with the widely use of ARINC 661 standard, couplings among software components are being reduced, which also results in the higher requirement for design of display manger software. The paper mainly focuses on configuration management, display reversion and curser management of display manager.
