Dashboard Purpose
The Safety Engineer Dashboard aggregates safety-focused key performance indicators (KPIs) across the entire project, enabling safety engineers to:- Monitor failure condition classification distribution
- Track Risk Priority Number (RPN) analysis across all system components
- Identify risk controls pending implementation
- Review the status of all safety analysis documents (FHA, SFMEA, DFMEA, PSSA, SSA, FTA, CCA)
- Locate and navigate to the highest-RPN failure modes requiring immediate attention
Dashboard Layout and Components
The Safety Engineer Dashboard follows the standard role dashboard layout:
Key Performance Indicators
The Safety Engineer Dashboard displays the following primary safety metrics:| KPI | Description | Source | Unit |
|---|---|---|---|
| Total Failure Conditions | Count of all identified failure conditions per ARP 4761 | FHA document | Count |
| Failure Condition Classification Distribution | Breakdown by 5-level severity (Catastrophic, Hazardous, Major, Minor, No Effect) | FHA work items | Count per level |
| Total Failure Modes | Count of failure modes identified across all SFMEA and DFMEA documents | SFMEA/DFMEA documents | Count |
| High RPN Count | Failure modes with RPN > 30 (pre- and post-mitigation) | FMEA tables | Count |
| Risk Controls Implemented | Count of riskControl work items with status = Implemented | Risk Control tracking | Count |
| Risk Controls Pending | Count of riskControl work items with status = Pending Implementation | Risk Control tracking | Count |
The exact KPIs displayed and their calculation formulas are configured via Velocity macros in the dashboard page.xml file. Verify the current metrics and thresholds in your project’s Safety Engineer Dashboard page.
Failure Condition Classification
The Safety Engineer Dashboard displays failure condition distribution across the 5-level ARP 4761 classification scheme:| Classification Level | Description | DAL Target | Count (Aero1 Example) | Probability Range |
|---|---|---|---|---|
| Catastrophic | Loss of function or capability that would prevent continued safe flight and landing | DAL A | — | Extremely Improbable (<10⁻⁹) |
| Hazardous | Severe degradation of safety margins; significant reduction in effectiveness | DAL B | — | Extremely Remote (<10⁻⁷) |
| Major | Moderate reduction in safety margins; significant reduction in effectiveness but not hazardous | DAL C | — | Remote (<10⁻⁵) |
| Minor | Minor reduction in safety margins; minor reduction in effectiveness | DAL D | — | Reasonably Probable |
| No Effect | No effect on safety or causal factors | DAL E | — | N/A |
RPN Distribution and Risk Ranking
The Safety Engineer Dashboard displays the Risk Priority Number (RPN) distribution for all failure modes identified in SFMEA and DFMEA documents. RPN is calculated as:| RPN Range | Risk Level | Color | Action Required |
|---|---|---|---|
| >30 | High | 🔴 Red | Immediate mitigation required; document risk control plan |
| 11–30 | Medium | 🟡 Yellow | Mitigation recommended; monitor during design phase |
| ≤10 | Low | 🟢 Green | Accept or defer; document acceptance rationale |
- Identify high-RPN failure modes requiring immediate attention
- Verify that risk controls are being implemented for medium-RPN items
- Track reduction in RPN through the design lifecycle
- Confirm that all residual RPNs fall within acceptable thresholds
Risk Control Implementation Status
The Safety Engineer Dashboard tracks the implementation status of all risk controls identified in the FMEA process:| Status | Description | Impact |
|---|---|---|
| Pending Implementation | Risk control identified but not yet incorporated into design | Failure mode remains at pre-mitigation RPN |
| Implemented | Risk control designed and incorporated into the architecture | Failure mode RPN updated to post-mitigation value |
| Closed | Risk control verification completed; effectiveness confirmed | Risk control accepted by safety authority |
Safety Documents Status
The Safety Engineer Dashboard provides a status overview of all safety analysis documents required by the aerospace standards:| Document Type | Standard | Description | Status Field |
|---|---|---|---|
| FHA | ARP 4761 | Functional Hazard Assessment — identifies failure conditions and severity classification | draft / inReview / approved / published |
| PSSA | ARP 4761 | Preliminary System Safety Assessment — maps failure conditions to system requirements | draft / inReview / approved / published |
| SSA | ARP 4761 | System Safety Assessment — verifies risk control effectiveness and closure | draft / inReview / approved / published |
| SFMEA | ARP 4761 | System-level Failure Mode and Effects Analysis — identifies failure modes and RPN | draft / inReview / approved / published |
| DFMEA | ARP 4761 | Design-level FMEA — component-specific failure analysis | draft / inReview / approved / published |
| FTA | ARP 4761 | Fault Tree Analysis — root cause analysis for high-RPN failure modes | draft / inReview / approved / published |
| CCA | ARP 4761 | Common Cause Analysis — identifies shared failure mechanisms across components | draft / inReview / approved / published |
Top Failure Modes by RPN
The Safety Engineer Dashboard includes a dedicated section listing the highest-RPN failure modes across the entire project. This list is typically sorted in descending RPN order and includes:| Column | Description |
|---|---|
| Rank | Ordinal ranking by pre-mitigation RPN |
| Failure Mode | Name/title of the failure mode work item |
| System Element | Component or subsystem where the failure mode is identified |
| Severity | ARP 4761 severity level (Catastrophic–No Effect) |
| Pre-Mitigation RPN | Initial RPN before risk control |
| Risk Control(s) | Linked riskControl work item(s) and status |
| Post-Mitigation RPN | Residual RPN after risk control implementation |
| Status | Verification status (pending / verified / closed) |
- Identify design areas requiring the most intensive safety analysis
- Assign risk controls to high-impact failure modes
- Track the effectiveness of mitigation strategies
- Plan certification activities for highest-risk items
The exact threshold for “top” failure modes (e.g., top 10, top 20, RPN > 30) may be configured per project. Verify the current dashboard configuration in your Aerospace Safety Solution instance.
