MIL-STD 882E · Task 106 · HTS

Task 106 — Hazard Tracking System (HTS) · Interactive Demo. Per MIL-STD 882E §101.2.6, the HTS is a closed-loop database tracking all identified hazards across the system life-cycle. This demo is pre-loaded with the SEDAC Reference UAV System dataset (12 hazards, 13 controls). All panels, filters, sorting, drilldowns, sliders, and charts are fully interactive. Upload your own data and generate PDF reports with the full licensed tool.

Gap Analysis

Open high-risk items · missing risk acceptance · unverified controls · MDE gaps

Open High/Serious RAC hazards — immediate action required

Residual High/Serious RAC — formal risk acceptance required (DAA/PM)

Missing risk acceptance documentation — acceptance field unpopulated

Missing verification method — hazards with no verification approach defined

Unverified controls on High/Serious hazards

Sensitivity Analysis

Program-wide RAC sweep · milestone risk posture simulation

§ Simulate additional severity/probability reductions across the HTS. Use to model risk posture at upcoming milestones (PDR, CDR) under different control effectiveness assumptions.
