Chapter 05 of 23 · SRP · Safety Risk Profile

Eight signals,one ICAO answer.

The Safety Risk Profile the system computes for you. Eight named components (base risk, trend, barrier health, active signals, CAPA exposure, data confidence, surveillance and audit load) fuse into one ICAO four-level answer per risk theme. Every profile is snapshotted and version-aware, so the board reads a saved answer it can reproduce, aligned to ICAO Doc 9859.

NGXNORTHGALE AIR · SYNTHETIC OPERATION
The profile moves
At Northgale the ground operations risk theme moves to Tolerable-watch. Not because someone typed it: the computed Safety Risk Profile absorbs the occurrence, the degraded barrier and the drifting indicator, and shows its work.

Why it holds

A risk score the system defends, not a slide someone typed.

Eight components fuse into one four-level answer per theme, snapshotted so the board reads a saved figure, not a live recalculation that shifts under them. The number is reproducible three years later, which is exactly what a regulator asks for.

What it does

The capabilities, on one record.

Computed profile

Base risk, trend, barrier health, signals, CAPA exposure, data confidence, surveillance and audit load, fused into one answer.

ICAO four-level

One acceptable, tolerable, undesirable or intolerable answer per risk theme, the way ICAO Doc 9859 frames it.

Snapshotted and pinned

The board reads a saved, version-aware answer, reproducible three years later, not a live recalculation.

Theme by theme

A profile per risk theme, so you see where risk is building, not one blended number for the whole airline.

The records it produces

Real records, one reference each.

Every record carries a stable reference and a source on every field. Nothing is silently overwritten, and the trail is the record.

The profile is computed from your data, not typed into a slide

The gate

Risk is computed from the operation.

The Safety Risk Profile derives from live records: base risk, trend, barrier health, active signals. A hand-typed green box is not a risk answer.
