--- title: "SMS Hazard Library — Bow-Tie Starting Points · Avioverse" description: "Eight SMS domains with sample clusters and operational ask-lines — starting points for a bow-tie you adapt in the workbench, not a blank EASA risk register." url: "https://avioverse.aero/risks" --- SMS hazard library # Start a bow-tie from an SMS domain, not a blank register. Eight domains as starting points. Metis drafts against your operation. You remain the chair. Eight SMS domains Nothing saved until you ask You remain the chair [Draft a bow-tie](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520a%2520hazard%2520in%2520my%2520operation.) ## Flight operations Starting points in this domain include runway excursion, unstable approach, GNSS interference, wildlife, fuel, operating minima, and night or ETOPS work. They open a bow-tie you adapt to the route and aerodrome you actually fly, rather than a register to copy. Start from [GNSS interference on approach](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520GNSS%2520interference%2520on%2520approach%2520in%2520my%2520operation.) [unstable approach in convective weather](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520unstable%2520approach%2520in%2520convective%2520weather%2520in%2520my%2520operation.) [wildlife hazard on a coastal aerodrome](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520wildlife%2520hazard%2520on%2520a%2520coastal%2520aerodrome%2520in%2520my%2520operation.) ## Human factors Human-factors starting points include fatigue, handover, procedural drift, and production pressure. Those themes become a bow-tie in the workbench, against a named shift or desk, not a catalogue of people-risks to paste in. Start from [fatigue on a night line shift](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520fatigue%2520on%2520a%2520night%2520line%2520shift%2520in%2520my%2520operation.) [inadequate handover between CAMO and the line](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520inadequate%2520handover%2520between%2520CAMO%2520and%2520the%2520line%2520in%2520my%2520operation.) [production pressure during a same-day release](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520production%2520pressure%2520during%2520a%2520same-day%2520release%2520in%2520my%2520operation.) ## Airworthiness and technical Airworthiness and technical themes include continuing airworthiness, incorrect maintenance, tooling, and configuration. Use them as a way into a bow-tie for the aircraft and the arrangement you actually hold, not as a parts list of defects. Start from [aircraft released with incomplete maintenance](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520aircraft%2520released%2520with%2520incomplete%2520maintenance%2520in%2520my%2520operation.) [pitot-static contamination](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520pitot-static%2520contamination%2520in%2520my%2520operation.) [contracted AMP not followed at a line station](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520contracted%2520AMP%2520not%2520followed%2520at%2520a%2520line%2520station%2520in%2520my%2520operation.) ## Ground operations Ground-operations themes include FOD, towing, GSE, turnaround, and de-icing. They are ramp starting points for a bow-tie you adapt to the stand and the night you actually run. Start from [aircraft towing in a congested hangar](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520aircraft%2520towing%2520in%2520a%2520congested%2520hangar%2520in%2520my%2520operation.) [FOD on a stand during a night turnaround](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520FOD%2520on%2520a%2520stand%2520during%2520a%2520night%2520turnaround%2520in%2520my%2520operation.) [GSE collision on a crowded apron](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520GSE%2520collision%2520on%2520a%2520crowded%2520apron%2520in%2520my%2520operation.) ## Conflict zones and security Conflict-zone and security themes include overflight, NOTAMs, and the security of aircraft and documents. The cluster is a map of where to start when the route or the station changes, not a list of named events. Start from [a new overflight of a conflict-adjacent FIR](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520a%2520new%2520overflight%2520of%2520a%2520conflict-adjacent%2520FIR%2520in%2520my%2520operation.) [a security change to aircraft access at a contracted station](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520a%2520security%2520change%2520to%2520aircraft%2520access%2520at%2520a%2520contracted%2520station%2520in%2520my%2520operation.) ## Economic Economic themes include commercial pressure against airworthiness, spare-part shortages, and contracted gaps. The bow-tie belongs in the workbench, against the actual commercial constraint, not as a finance-risk roster. Start from [spare-part shortage driving a deferred defect](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520spare-part%2520shortage%2520driving%2520a%2520deferred%2520defect%2520in%2520my%2520operation.) [commercial pressure to dispatch with an open MEL item](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520commercial%2520pressure%2520to%2520dispatch%2520with%2520an%2520open%2520MEL%2520item%2520in%2520my%2520operation.) ## Environmental and natural Environmental and natural themes include weather, volcanic ash, wildlife, and contaminated surfaces. They are climate and terrain starting points for a bow-tie, not a weather-event catalogue. Start from [winter contaminated-runway operation](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520winter%2520contaminated-runway%2520operation%2520in%2520my%2520operation.) [volcanic-ash encounter on a planned route](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520volcanic-ash%2520encounter%2520on%2520a%2520planned%2520route%2520in%2520my%2520operation.) ## Cybersecurity Cybersecurity themes include GNSS jamming and spoofing, Part-IS duties, and the integrity of EFB and ground systems. Draft the assessment in the workbench against the system that actually failed. Start from [GNSS jamming during approach](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520GNSS%2520jamming%2520during%2520approach%2520in%2520my%2520operation.) [a suspected EFB data-integrity event](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520a%2520suspected%2520EFB%2520data-integrity%2520event%2520in%2520my%2520operation.) How a bow-tie starts ## From a domain to a draft you still own. The library is a map of where to begin. The assessment runs in the workbench. 1. 1 ### Pick a starting point Choose a domain and an operational ask — a scenario a postholder would type, not a catalogue row to copy. 2. 2 ### Metis drafts the bow-tie Threats, barriers and consequences against your operation, not a blank register. 3. 3 ### You review Nothing is saved until you ask. You remain the chair. The method in full: [a worked bow-tie](https://avioverse.aero/articles/bow-tie-risk-assessment-aviation-example) · [calibrating the risk matrix](https://avioverse.aero/articles/aviation-risk-matrix-likelihood-severity) · [what the EASA rules require](https://avioverse.aero/guides/easa-hazard-identification-safety-risk-management) Multi-discipline workshop ## Each desk answers in isolation. You remain the chair. Metis runs the desks this change actually touches, against the manuals you name, then you merge. Nothing is saved until you ask. Example ask > “We are opening a new route. I want a risk assessment covering flight operations, security, maintenance and ground-ops risks, based on our current procedures — consult the OMA, CAME Part-3, OMC and Ground Ops Manual section X.” ### Isolated desks for this change - #### Flight operations Consults OMA. Does not see the other desks. - #### Security Consults OMC. Does not see the other desks. - #### Maintenance Consults CAME Part-3. Does not see the other desks. - #### Ground operations Consults Ground Ops Manual, section X. Does not see the other desks. You remain the chair. Adopt, reject or merge each desk into one draft. The assessment is not saved until you ask. Early access ## The register stays blank until you start a bow-tie. [Draft a bow-tie](https://avioverse.aero/register?redirect=https%3A%2F%2Fapp.avioverse.aero%2Fchat%3Fdraft%3DDraft%2520a%2520risk%2520assessment%2520for%2520a%2520hazard%2520in%2520my%2520operation.) Pick a domain, draft with Metis, and review before anything is saved.
