Structured reference for incident severity, occurrence classification, and operational context. Bincident provides source-aligned guidance for consistent interpretation across the decision surface.
Severity Framework
How Severity Works
Severity is a five-level classification scale used across Bincident. Each occurrence is assigned one level using documented outcome, injury status, aircraft damage, and operational risk indicators.
| Level | Maps To | Description |
|---|---|---|
| L5Catastrophic | Airframe loss and/or fatalities | Highest severity category for occurrences with fatal outcomes or total aircraft loss. |
| L4Critical | Major damage, serious injuries, or near-catastrophic risk | Very serious occurrences requiring immediate control actions, often with severe damage. |
| L3Major | Serious safety event needing urgent operational response | Substantial incidents where safety margins are reduced and rapid intervention is required. |
| L2Moderate | Notable incident with limited direct consequences | Manageable incidents such as precautionary actions, diversions, or contained technical issues. |
| L1Minor | Low-impact occurrence with minimal safety effect | Lowest-impact category for precautionary or procedural events with little direct risk. |
L5 - Catastrophic
Highest severity category for occurrences with fatal outcomes or total aircraft loss.
L4 - Critical
Very serious occurrences requiring immediate control actions, often with severe damage.
L3 - Major
Substantial incidents where safety margins are reduced and rapid intervention is required.
L2 - Moderate
Manageable incidents such as precautionary actions, diversions, or contained technical issues.
L1 - Minor
Lowest-impact category for precautionary or procedural events with little direct risk.
