ADS-79D-HDBK Downloaded from https://www.everyspec.com It is in the Maintenance Management System where the individual aircraft parts configuration would traditionally be kept and maintenance schedules would be generated. Unscheduled maintenance activity and trouble-shooting support is likely to be generated by the CBM Ground Station. Figure K-2 breaks these major elements down into other definable and configurable system elements including dedicated CBM Sensors or remote ―smart‖ boxes that may be part of the end-to-end credit path. Mixed in with the application software are other software components such as operating system software and databases.
In some cases these are COTS components which must be controlled with respect to their influence on the credit being sought. After all of the major software modules are defined and controlled, the system will still not perform the intended credit processing unless the CBM configuration files defining the aircraft configuration, CBM data acquisition requirements, acquisition schedules, and finally specific CI thresholds are controlled. FIGURE K-2. Elements of CBM system architecture These elements must be carefully tracked and controlled during the design process and documented before formal V&V testing.
The final V&V of a Credit must be verified and validated on a production or production representative test configuration. 191
