One record.The whole investigation.
SeyAero is the evidentiary record for aviation accident and near-miss investigation. Every fact an investigation holds, recorder data, cockpit audio, radar tracks, weather, maintenance history, crew and passenger records, enters one synchronised, tamper-evident record that the analysis, the report and the defence of the report all draw from. The account of what happened and the proof of how it was reached are the same object.

Not another tool
Investigations run on files. They should run on infrastructure.
One evidentiary record holds every fact, the synchronised reconstruction, the ranked hypotheses, the search zones and the report. Every fact enters once, is hashed and time-stamped, sits on one master clock, and stays bound to every conclusion it supports.
- The record is the case
- Evidence, analysis and report are views onto one object, not three artefacts that can drift apart.
- The reasoning is preserved
- Every drafted sentence traces back to the exact record it rests on, years later, under any reviewer.
- The method is published
- Assumptions, failure modes and back-test results are public documents, so the infrastructure can be judged, not just bought.
- The organisation compounds
- Recommendations, precursor patterns and sealed predictions outlive any single case and any single investigator.
Evidence intake
Every source an investigation touches, in one ledger.
Parameter traces, sampling gaps, sensor drift.
Transcripts, callouts, crew workload markers.
Track reconstruction and secondary returns.
METAR, SIGMET, icing and shear layers.
Deferred defects, cycles, component history.
Duty time, ratings, passenger and load data.
What the record enables
The whole investigation, running on one record.
Seven capability groups, from the first squawk to a signed, verifiable report — all reading from, and writing back to, the same evidentiary record.
Live capture
The case opens itself
- Emergency squawk (7500/7600/7700) auto-opens a live case
- Streaming recorder telemetry ingested while airborne
- Live ATC frequency recorded and auto-transcribed
- NEXRAD radar, lightning and turbulence pulled to the aircraft's position
- Rescue-window alerts estimate terrain, exposure and response urgency after signal loss
Reconstruction
One clock, one account
- Master timeline synchronising FDR, CVR, radar and observers
- Physics-based trajectory fitting through sparse or noisy tracks
- 3D flight playback from ingested telemetry
- Ranked causal hypotheses with confidence scoring
Occurrence analysis
Every accident class, one discipline
- All-phase physics: take-off, climb, cruise, approach, landing and ground roll
- Overrun, obstacle and building strike, midair conflict geometry and TCAS advisory compliance
- Rotorcraft solved on a rotary-wing frame: autorotation energy, height–velocity, vortex ring, rotor integrity
- Propeller aircraft solved on a propeller frame: feathering drag, Vmca margin, overspeed, blade-signature power at impact
- Ditching, in-flight fire and icing hazard frames with explicit uncertainty
- Fuel, pressurisation, incapacitation, loading, turbulence, wake and deliberate-interference frames
- Structural break-up and lifting-surface separation with bounded wreckage estimates
- Energy-bounded counterfactuals, survivability bands and evidence-gap radar
- Probable cause is refused where the evidence cannot carry it — see the analysis engines record
Hull-loss search
Where to look first
- Monte Carlo end-of-flight and drift modelling
- Recovered-debris backcasting with dated currents and selectable drift models
- Probability contours and prioritised search sectors
- Bayesian re-weighting as each sector is cleared
- Date-line crossings are marked indicative rather than presented with false precision
- Benchmarked against historical losses on the validation record
Reporting
Accepted across borders
- One-click ICAO Annex 13 draft bound to verified evidence
- Every sentence footnoted to the exact FDR row or transcript line
- Renditions in 20 languages with a frozen terminology glossary
- Signed release with staleness tracking on every translation
Evidence integrity
Defensible in an inquiry
- Zero-knowledge vault — files encrypted on-device before upload
- SHA-256 hashing at ingest with a tamper-evident audit chain
- Notarised anchors anyone can check at /verify, no account needed
- Reviewer approval gate before any transcript becomes evidence
- Independent security assurance documentation, released under NDA
Programme control
Run it as an organisation
- Role-based access for investigators, leads and case owners
- Scoped external adviser packs with conflict declarations and selected-file access
- Privacy-preserving fleet-wide precursor and near-miss pattern analytics
- Procurement desk: proforma, PO upload, counter-signed order forms
- Multi-jurisdiction privacy posture — GDPR, CCPA/CPRA, LGPD and more

Hull-loss localisation
Where to send the ship, in priority order.
Last known state, performance envelope, wind transport and sea drift are propagated through a Monte Carlo end-of-flight model. The output is a probability field with ranked search sectors that re-weight themselves as each sweep comes back empty — validated against real hull losses across every environment category.
How it works
Ingest everything
Write a free account of the occurrence, confirm the drafted case summary, then follow a live evidence guide. Auto-ingest can assemble ADS-B, weather and available ATC material while every record remains pending, verified or conflicted.
Synchronize the truth
Records are aligned onto one master timeline so cockpit audio, telemetry and external observations sit on the same clock. Conflicts surface instead of hiding in a spreadsheet.
Reconstruct and rank
The reconstruction engine builds the causal chain and scores competing hypotheses by confidence, so investigators argue over evidence, not over file formats.
Locate the wreckage
For hull-loss events, last known state, drift and performance envelopes produce probability contours and prioritized search sectors.
Built for
Annex 13-ready evidence chain and reporting.
Fleet-wide precursor and near-miss patterns.
Component and software fault correlation.
Defensible causation with traceable provenance.
