Downloaded from https://www.everyspec.com ADS-79D-HDBK Usage Credit: Credit awarded to equipment maintenance practices (i.e. inspections, overhaul, on wing life limit) based on selected aspects of actual service usage history of specific monitored equipment versus design usage of general equipment population. Usage Spectrum: Operating condition distribution used in fatigue analysis which allocates time or number of occurrences over a period of operation based on mission profile, theater, and unit. Validation: The process of evaluating a system or software component during, or at the end of, the development process to determine whether it satisfies specified requirements. Verification:
Confirms that a system element meets design-to or build-to specifications. Throughout the systems life cycle, design solutions at all levels of the physical architecture are verified through a cost-effective combination of analysis, examination, demonstration, and testing, all of which can be aided by modeling and simulation.
