An improved integrated avionics system having a plurality of line replacement units (LRUs) is disclosed. At least one LRU stores in its memory software and configuration data stored and used by another LRU in the system. Upon detecting a new LRU installation, the at least one LRU may be configured to copy to its internal memory the software and configuration data loaded to the new LRU. The LRU may also store a table in its internal memory identifying each LRU that has been installed in the system, when each LRU was installed, and a copy of configuration and software data loaded to each LRU. If one of the LRUs in the system needs to be replaced, the LRU may determine which software and configuration data is applicable to the replaced LRU and load the determined software and configuration data to the new LRU, thereby improving the loading and installation process.
