NOTAMs by FIR

FIR vs aerodrome search

An aerodrome search returns NOTAMs associated with a specific airport ICAO code. An FIR search returns notices applicable across the wider Flight Information Region — for example when analysing en-route restrictions, airspace activations, or regional navaid outages affecting multiple aerodromes.

Choose FIR search when the operational question spans the region rather than one station. Choose NOTAMs by airport ICAO when the occurrence or audit point is aerodrome-specific.

Examples

EBBU (Brussels FIR), EGTT (London FIR), LFFF (Paris FIR), EDWW (Bremen FIR), KZNY (New York FIR), KZLA (Los Angeles FIR), ZSHA (Shanghai FIR), YMMM (Melbourne FIR) — enter the FIR ICAO code and historical date on the search form.

FIR snapshots may be larger than single-aerodrome results. Optional NOTAM number filtering helps isolate a specific notice referenced in documentation.

Investigative and legal applications

Accident boards examining en-route phases often need FIR-level published information for the relevant UTC date. Lawyers and insurers may likewise require regional airspace NOTAMs when disputes involve routing, restrictions, or temporary danger areas.

NOTAM History queries archive APIs with approximately two years of depth. Results are for documentation — not pre-flight briefing. Combine FIR output with aerodrome queries for departure and destination as needed.

Regional guides and pricing

Pricing: €9.99 one-off search, €29.99/year subscription (ten searches), €29.99 top-up packs. See how it works.

En-route and oceanic FIR considerations

Long-range operations crossing multiple FIRs may require several FIR archive queries to reconstruct en-route restriction environments.

Temporary restricted areas and military exercise NOTAMs often appear at FIR level with geographic descriptions in E-line text.

Budget FIR-level searches in investigation plans early — results sets can be large. Optional NOTAM number filters help when ACARS references a specific identifier.

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.

Oceanic and remote continental FIR searches may return notices whose geographic description requires chart correlation. Investigators should pair FIR archive output with planned track plots when assessing whether a restriction applied to the actual path flown.

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

Military exercise NOTAMs at FIR level may use plain-language geographic descriptions that require chart overlay during investigation. Archive email output should be preserved with the track plot used for applicability analysis in the final report or expert appendix.
