What is Safety Risk Management?

Aviation safety risk management software holds an airline's hazard register and tracks how each risk is scored and controlled under its SMS. Safety Risk Management keeps that register live, scoring risk and tracking mitigations, for SMS managers. Each hazard is a bowtie whose barriers seven agents measure every night from safety reports, flight-data events, audit findings and maintenance alerts; when a barrier weakens they re-score the risk on your matrix, challenge it and draft mitigations with a test. Hazard owners approve, edit or reject and sign.

The problem

Why aviation safety risk management runs a quarter behind the operation

Aviation safety risk management under 14 CFR Part 5 asks an airline to identify hazards, assess and control the risk, and show that its risk controls work. In many SMS offices the hazard register is a spreadsheet or a module reviewed once a quarter. Barriers are rated once in a workshop, and the evidence that would show one slipping — an ASAP report, three flight-data exceedances, a NOTAM, an audit finding, a reliability alert — sits in other systems that nobody reads against the register.

So the register says “effective” while the line says otherwise. The same hazard is opened again under a new name, and an acquisition doubles the problem. Mitigations close without a test of whether they worked, and the Safety Review Board papers and the FAA and IOSA evidence are rebuilt by hand every month. The first sign that a barrier failed is often the next report.

One weakening barrier, from three events to a signed decision

Corvane Airways, a fictional network carrier with 312 aircraft, keeps 146 hazards and 412 barriers. In the week of October 6 it rained three days at SFO and the ILS 28L glideslope was out of service. On Thursday, October 15, here is what happens, screen by screen, in the working solution.

  1. 01Thursday, 08:00

    What the agents found overnight, on one screen

    Renata Sallis · Safety Risk Manager

    Renata's day starts with the agents' note: 148 new items read, 61 linked to their hazards on their own, and at SFO three unstable approaches in one week continued to landing. Three hazards moved this week, 27 new items wait for her, and 7 mitigations are overdue. “Needs you” lists 7 decisions, each with one next step.

    “7 decisions · agents never act unseen.”

  2. 0202:10 – 02:58

    Every report and event linked to one hazard, or held for a person

    Linking Agent

    The Linking Agent reads safety reports, flight-data events, audit findings and reliability alerts from seven sources. It links on its own only at 0.90 confidence or above and only onto a barrier that is holding. Everything else waits in New evidence with its reason: a DEN stop-bar report filed under ground collision that reads as a runway incursion precursor, four GPS reports near OAK that fit no hazard, and three hazards someone opened twice.

    “Waits for you: B1 on HZ-0117 is weakening since 02:48 tonight (rule L2).”

  3. 0302:48

    Barrier B1 is weakening — measured, not declared

    Barrier Watch Agent

    On HZ-0117, runway excursion on landing, wet runway, barrier B1 is “Stable by 1,000 ft, go around if not” from FOM 4.12.3. At SFO three unstable approaches were continued in 7 days with no go-around, against 0.4 a week, and the network go-around rate on unstable approaches fell from 71% (141 of 198, April to June) to 58% (124 of 214). Each event on the barrier — an A321neo at Vref +19 kt at 1,000 ft, a de-identified 787-9 crew report, a 737-8 1.4 dots high at 700 ft — opens its source passage, and the 28L glideslope NOTAM hangs from the barrier it weakens.

    “At about 800 ft we were high and fast. I called it but we continued.” — ASAP-26-3317, de-identified

  4. 0403:14 – 03:16

    Re-scored from 2A Tolerable to 3A Unacceptable, then challenged

    Risk Scoring Agent and Challenge Agent

    The Risk Scoring Agent moves likelihood from Remote to Occasional — Occasional in SMS Manual 3.4 covers events seen more than once in a quarter at one station, and this one was seen three times in a week — and keeps severity at Catastrophic: 3A, Unacceptable, confidence 0.86. The Challenge Agent reads the same evidence on its own and agrees with the direction, but notes two of the three events came after the glideslope went out and sets a re-score review for October 26, a week after the NOTAM ends.

    A severity change needs two independent reasons (rule R6). Disagreement is always shown, never averaged away.

  5. 0503:20

    Three mitigations, each with an owner, a date and a test

    Mitigation Agent

    M-0117-07, an SFO wet-runway brief with the go-around gate called at 1,000 ft by the pilot monitoring (bulletin FOB-26-31). M-0117-08, a daily flight-data watch of every SFO approach for 30 days, owned by Lena Kovac. M-0117-09, a recurrent simulator scenario on the high-energy wet approach, owned by Capt. Owen Marsh. The predicted residual risk is 2A Tolerable. Once approved, each sits on the mitigations list with its owner, due date and test of success.

    The test: no unstable approach continued below 1,000 ft at SFO for 30 days, and a network go-around rate of at least 70% over 60 days.

  6. 0608:20

    She asks why not wait for the glideslope to return

    Capt. Elena Voss · Director of Flight Safety

    Elena asks the agents in the same thread. The Challenge Agent answers with its sources: the barrier was already weak before the outage — the go-around rate fell from 71% to 58% since July — and the SFO airport brief has no entry for flying with the 28L glideslope out. If SFO is clean by October 26, the score can come back to 2A.

    Every answer is cited; each number opens the passage it came from.

  7. 07Signed

    Approved with edits, signed

    Capt. Elena Voss · Director of Flight Safety

    Elena opens Edit and brings the SFO brief forward from October 17 to October 16; the agents re-check the residual risk with her edit — still 2A Tolerable. She approves with reason code A2 — Approved with edits — and signs. The register now carries 3A Unacceptable, approved by her, and the Mitigation Agent sends the bulletin to Flight Standards, starts the SFO flight-data watch and tells Malcolm Ashby.

    “I, Capt. Elena Voss, sign this decision. It is recorded with the time, the reason and the sources.”

  8. 08On the record

    Who decided what, and why

    Audit trail

    Every step — the link at 02:31, the barrier at 02:48, the re-score, the challenge, the drafts, Elena's edit and her signed approval at 08:20, the Board item at 08:12 — is on the audit trail with the person or agent, the time, the reason code and the sources. The trail is kept seven years and cannot be edited.

  9. 09October 21

    The residual risk goes to the Safety Review Board

    Malcolm Ashby · SMS Accountable Executive

    Because the score is Unacceptable and the residual risk keeps Catastrophic severity, only the Accountable Executive may accept it. The Board Secretary Agent has already put HZ-0117 first on the October 21 agenda, with a one-paragraph case citing the three events and the go-around rate, next to five other items. Malcolm accepts, returns or defers each with a reason and a signature, and the minutes are drafted from the signed decisions.

    “Residual 2A with Catastrophic severity is yours to accept.”

Built on the engine

7 agents. Each with one job, and hard limits.

Seven agents link the evidence, measure every barrier, re-score and challenge the risk and draft mitigations; hazard owners decide.

Linking Agent

Reads every new safety report, flight-data event, audit finding and reliability alert each night, links it to the hazard and barrier it touches, proposes a new hazard when nothing fits, and flags two hazards that describe one risk.

  • Links on its own only at 0.90 confidence or above, and only onto a barrier that is holding
  • Never edits a hazard; reads de-identified reports only
Barrier Watch Agent

Recomputes the health of every barrier each night from the linked evidence against its baseline — Holding, Watch, Weakening or Failed — and says what changed in one sentence, with escalation factors such as NOTAMs or system changes.

  • Always states the sample and the baseline
  • Cannot change a score
Risk Scoring Agent

Re-scores likelihood and severity on the airline's own 5×5 matrix when a barrier weakens or fails, and explains the move with the manual passage behind it.

  • Proposes only; the hazard owner decides
  • Changes severity only with two independent reasons; never lowers a score without a person
Challenge Agent

Reads the same evidence on its own, without the proposer's reasoning first, and agrees or disagrees with every re-score and mitigation before a person sees it.

  • Cannot approve
  • A disagreement is always shown to the owner, never averaged away
Mitigation Agent

Drafts mitigations with an owner, a due date, a predicted residual risk and a measurable test of success; reminds owners, escalates late actions and runs the effectiveness test when its window ends.

  • Cannot approve, extend or close a mitigation
  • Proposes effective or reopen; a person decides
Change Assessment Agent

For each operational change, proposes the hazards from the register that apply and the new ones it lacks; runs the merge of an acquired airline's hazard register by top event, threats, barriers and evidence.

  • Cannot sign an assessment or a merge
Board Secretary Agent

Drafts the Safety Review Board agenda, each item's one-paragraph cited case, the minutes from the signed decisions, the monthly risk profile and the FAA and IOSA evidence.

  • Never records a decision a person did not make
  • Shows a gap in the evidence, never hides it
Hazard owners and the Accountable Executive

Decide every score, mitigation and acceptance. The agents propose; a named person decides.

Ask in plain words

Ask the safety agents, in plain words

Ask about any hazard, barrier, mitigation or Board item, or tell the agents what to do. Every answer points to its source, and every instruction is logged.

Why is the runway excursion hazard now Unacceptable?

Because barrier B1, “stable by 1,000 ft, go around if not”, is weakening: three unstable approaches at SFO in one week were continued to landing, and the network go-around rate fell from 71% to 58%. Seen three times at one station in a week is “Occasional” in your manual, and Occasional × Catastrophic is 3A, Unacceptable.

Why not wait for the glideslope to return?

Because the barrier was already weak before the outage: the network go-around rate on unstable approaches fell from 71% to 58% since July, and the SFO brief has no entry for flying with the 28L glideslope out. The outage ends Oct 19. The Challenge Agent has set a re-score review for Oct 26; if SFO is clean by then, the score can come back to 2A.

Which barriers are weakening this week?

Nine are weakening and one has failed. The ones that matter most: HZ-0117 B1, the stabilized approach at SFO; HZ-0073 B2, the MEL interval reminder, failed after the Sep 1 system merge; HZ-0142 B2, the layover hotel standard; and HZ-0031 B1, two wing walkers at night.

Show me what is overdue

Seven mitigations are overdue: M-0067-02 shipper screening (13 days, escalated), M-0098-03 turbulence briefing (9 days), M-0012-03 ramp telematics (7 days) and M-0073-04 MEL reminders (6 days), plus three on track for an extension.

Every statement opens its sourceEach agent statement, score and number carries a citation that opens the passage it came from — the flight-data event, the ASAP report, the NOTAM, the FOM or SMS Manual section.
Hazard owners decide and signAgents propose; the hazard owner approves, edits or rejects each re-score and mitigation with a reason code and a signature, inside 3 business days by default.
Risk accepted at the right levelA Tolerable risk may be accepted by its hazard owner, with mitigation. Only the Accountable Executive, at the Safety Review Board, accepts Unacceptable risk or any residual risk with Catastrophic severity, and is told of an Unacceptable score within 24 hours.
Agents that check each otherThe Challenge Agent reviews every re-score and mitigation on its own and cannot be turned off. When agents disagree, as on the crew fatigue hazard, both views go to the owner.
De-identified, read-only evidenceVoluntary reports are read only after they are de-identified and accepted, and the agents have read-only access to every source. They never contact frontline staff, close a mitigation or lower a score without a person.
An audit trail kept seven yearsEvery action by a person or an agent is recorded with the time, the reason and the sources, and cannot be edited. Changes to the matrix and rules are signed and logged, and exports are signed and dated.

Questions

What airline safety teams ask about aviation safety risk management.

What is aviation safety risk management software?

Aviation safety risk management software holds an airline's hazard register and tracks how each risk is scored and controlled under its SMS. Safety Risk Management keeps that register live, scoring risk and tracking mitigations, for SMS managers. Each hazard is a bowtie whose barriers seven agents measure every night from safety reports, flight-data events, audit findings and maintenance alerts; when a barrier weakens they re-score the risk on your matrix, challenge it and draft mitigations with a test. Hazard owners approve, edit or reject and sign.

What does 14 CFR Part 5 require for safety risk management (SRM)?

Subpart C asks an operator to apply safety risk management to changes (§5.51), identify hazards (§5.53), assess and control the risk (§5.55) and notify interfacing organizations of hazards they must mitigate (§5.57). Subpart D asks it to monitor safety performance and assess whether its risk controls are effective (§5.71–5.73). The solution maps the register and its evidence to each of these, and shows any gap.

How do you know whether a risk control is working?

Each barrier's health is recomputed every night from the evidence linked to it, against its own baseline, and marked Holding, Watch, Weakening or Failed. Each mitigation carries a measurable test of success agreed when it is approved; when the window ends the Mitigation Agent runs the test and proposes effective or reopen, for a person to decide.

What is a bowtie analysis in aviation safety?

A bowtie draws one hazard with its threats on the left, the top event in the middle and the consequences on the right, with the barriers that prevent and recover in between. In Safety Risk Management each barrier carries health measured from evidence, the events that hit it this week and the factors that weaken it, and each opens its source.

Who can accept risk, and do people stay in control?

People decide everything. Agents propose; hazard owners approve, edit or reject with a reason code and a signature. A Tolerable risk may be accepted by its owner, while only the Accountable Executive at the Safety Review Board accepts Unacceptable risk or any residual risk with Catastrophic severity. The agents never close a mitigation or lower a score without a person.

Does it handle management of change and an airline merger?

Yes. For each operational change — a new route, station or handler — the Change Assessment Agent proposes the hazards from the register that apply and the new ones, for sign-off before the change goes live. For an acquisition it compares the other airline's hazard register with yours and proposes matches and new hazards for the two safety managers to decide.

Can we use our own risk matrix, based on ICAO Doc 9859, and our SMS Manual rules?

Yes. The 5×5 tolerability matrix, who accepts each level, the auto-link threshold, the weakening threshold and baseline look-back, decision clocks, reminders and escalation are settings owned by your SMS administrator, signed and logged. You can start by importing your current spreadsheet register.

How long does it take to go live?

The Agentic Solution Engine builds and deploys it from your requirements and documents — your SMS Manual, risk matrix, hazard register and connections to your reporting, flight-data, audit and maintenance systems — and it goes live once every quality gate has passed. We will walk you through it on your own register first.
