An aviation hazard register, built on bow-ties
In 50 words
A hazard register lists what could cause harm, the risk each hazard carries and the controls that hold it back. In eAviora every hazard sits on its risk family’s bow-tie, with threats, consequences and named barriers, and each barrier is rated whenever an event tests it.

What it does
Four things, done on the record
A bow-tie per risk family
Threats, the top event and consequences on one model, with the barriers between them named.
Barriers rated when tested
Effective, partially effective, ineffective or missing: each barrier an event tested is rated by a person.
Initial and residual risk
Scored on the ICAO 5 by 5 matrix, with the forecast residual and who approved it.
Where each hazard came from
A hazard report, an occurrence trend, an audit finding, a risk assessment, a flight data event or a proposed change.
In the product
A hazard, in treatment
- The next step and what it waits on: a treatment decision, its rationale and a mitigation plan.
- Initial risk and the forecast residual, on the same matrix.
- The occurrences that relate to it and the action that mitigates it.
The rule it holds
A barrier nobody has assessed is not counted as protection.
Barrier health shows an unrated barrier as not assessed, never as effective.

Short answers
Do we start with an empty register?
No. The library ships 85 bow-tie models with 682 named barriers. You assess them against your operation and add hazards of your own.
Can we use our own risk matrix?
Risk is scored on the ICAO 5 by 5 matrix, the same for every operator, so a band means the same thing wherever it is read.
Where do hazards come from?
A hazard report, an occurrence trend, an audit finding, a risk assessment, a flight data event or a proposed change. The source stays on the record.
