Key Features

  • Functional Hazard Assessment (FHA) — Identify failure conditions, classify severity, and allocate Design Assurance Levels (DAL A–E) per ARP 4761
  • System and Design FMEA — Score failure modes using RPN (Severity, Occurrence, Detection) and track mitigation actions
  • Advanced Safety Analysis — Create fault trees, common cause analyses, and PSSA/SSA documents for comprehensive hazard management
  • DO-326A Security Assessment — Model threat scenarios and allocate Security Assurance Levels (SAL) for airborne cybersecurity
  • V-Model Traceability — Link customer requirements through system, design, and verification stages with automated compliance matrix
  • Multi-Standard Compliance — Support for DO-178C, ARP 4754A, ARP 4761, DO-254, DO-160G, MIL-STD-882E, and more
  • Role-Based Dashboards — Safety engineers, design engineers, V&V, configuration managers, and program managers each have tailored views
  • Certification Readiness Scorecard — Track progress toward compliance objectives and certification milestones
