Downloaded from https://www.everyspec.com ADS-79D-HDBK The sample list of components in Table B-V contain subassemblies and individual parts that are also often tracked by serial number to determine operational history, so databases containing configuration information should follow the work unit code (WUC) structure and serial number tracking requirements set by the initial design specifications. 52 TABLE B-IV. Fatigue life management validation challenges Validation Loop Primary Question Challenges to Overcome Usage Validation How well does the Design Usage Spectrum represent operational usage?
Sampling issues (must represent all units, missions, theaters, and threat environments) Maneuver standards (does regime recognition cover flight load survey regime?) Loads Validation How well do Flight Load Survey loads represent operational loads? Loads variability (pilots, air quality, gusts, aircraft manufacturing tolerances) Load binning effects Maneuver standards (does regime recognition cover flight load survey loads?) TABLE B-V.
