NOTAMs for flight safety audits

Audit documentation use cases

Auditors seek objective published data — not reconstructed memory of what briefing screens may have shown weeks ago.

• Verify dispatch briefing completeness for sampled flights on specific dates
• Demonstrate what NOTAMs were published at stations during audit window observations
• Support hazard register entries tied to temporary restrictions or infrastructure work
• Document corrective action follow-up after NOTAM-related operational findings
• Provide evidence for regulatory authority or IOSA-style safety audits

Retrieve the active set by ICAO and date

NOTAM History compiles archived NOTAMs active at a 4-letter ICAO aerodrome or FIR on a chosen date up to approximately two years back. Results arrive by email in standard ICAO format for attachment to safety reports and audit binders.

Optional NOTAM number filtering isolates individual notices when testing specific briefing line items. See NOTAM number lookup for combined search parameters.

SMS integration considerations

Safety officers should define when archive retrieval is required in procedures — for example after significant incidents, recurring briefing discrepancies, or authority requests. Archive output complements FOQA, ASAP, and voluntary reporting data; it does not replace operator briefing system logs where those are authoritative internally.

NOTAM History is not for live operational briefing. Pre-flight processes should continue using approved current NOTAM products.

Subscription value for operators

Operators with ongoing audit programmes benefit from €29.99/year subscriptions (ten searches) or €29.99 top-up packs rather than ad hoc one-off fees. See pricing and NOTAMs for airlines and operators.

For occurrence investigation overlap, see NOTAMs for accident investigation. General workflow: how it works.

Sampling methodology for NOTAM audits

Effective audits sample flights across stations, seasons, and operational types — then verify published NOTAM environments on sampled dates via archive retrieval.

Document discrepancies between archived active sets and dispatch releases as findings with severity ratings under SMS frameworks.

Integrate archive retrieval into audit checklists alongside OFP storage, weather retrieval logs, and crew briefing signatures.

Professional use summary

NOTAM History delivers archived NOTAMs by ICAO aerodrome or FIR and historical validity date, with approximately two years of archive depth via professional aviation data APIs. Pricing: €9.99 one-off, €29.99/year (ten searches), €29.99 top-up. Email output uses ICAO plain-text format for investigators, lawyers, insurers, safety officers, and operators. Not for pre-flight briefing — use FAA NOTAM Search or approved operator systems for current US and international operations before flight.

NOTAM History queries professional archive APIs by 4-letter ICAO aerodrome or FIR code and historical validity date, returning ICAO plain-text NOTAM output by email within seconds. Archive depth is approximately two years where supported. Pricing is €9.99 per one-off search, €29.99 per year including ten searches, or €29.99 top-up packs. The service is designed for investigators, aviation lawyers, insurers, safety officers, and operators who need expired NOTAMs no longer shown on FAA NOTAM Search or briefing apps — and is not for pre-flight operational briefing.

Auditors presenting findings to the accountable manager should include archived NOTAM text—not screenshots of current briefing apps—when alleging briefing gaps. ICAO-format archive email gives reviewers verifiable content tied to ICAO code and UTC date parameters recorded in the audit workpaper.

Archive retrieval on notamhistory.com remains the practical path for notams for flight safety audits workflows when expired notices are unavailable on FAA NOTAM Search or standard briefing feeds.

Present audit findings referencing archived NOTAM identifiers (series/number/year) so responsible managers can reconcile dispatch filtering rules against specific notices rather than debating generic briefing completeness statements.
