Abstract
A group of rotorcraft original equipment manufacturers (OEMs) and military and commercial operators have come together to review the current state of mechanical diagnostics (MD) for on board rotorcraft Health and Usage Monitoring Systems (HUMS). HUMS has become an integral part of the modern rotorcraft both in commercial and military operations to enhance safety and enable Condition-Based Maintenance (CBM). Commercial oil and gas operators depend on the HUMS vibration monitoring and MD to comply with regulations and customer requirements for ensured safety of off-shore transportation. Under the auspices of the HUMS Technical Committee within the American Helicopter Society (AHS), the authors have assessed the performance of HUMS MD through both quantitative and qualitative means. First, results from the U.S. Army fleet, which comprises thousands of deployed HUMS on multiple aircraft models, were examined. Second, qualitative surveys of both commercial/military operators and rotorcraft/HUMS original equipment manufacturers (OEMs) were completed. Finally, a literature survey focused on HUMS research and development (R&D) and operational analysis was conducted. Based on this assessment, gaps in the performance of current HUMS MD, needs for future R&D, and challenges to closing those gaps are identified. Collaborative, pre-competitive efforts are also recommended to help close the gaps and generally raise the performance of HUMS MD to enable further enhancements to safety and to support expanded CBM initiatives.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
