One Million NOTAMs Processed: What We’ve Learned (and What’s Next)

Notamify has officially crossed a major milestone: we’ve processed more than 1,000,000 NOTAMs. From aerodrome operations to complex airspace restrictions, our AI-powered interpretation has helped pilots, dispatchers, and analysts turn raw notices into clear, actionable intelligence.

Below you’ll find a chart from our NOTAM volume analysis, along with the key insights we’ve learned at scale. We’re also highlighting our public Archive endpoint for historical analysis.

Highlights at 1,000,000 NOTAMs

• Aerodrome dominates: Runway and taxiway operations are the single largest drivers of NOTAM volume across major airports.
• Airspace restrictions remain significant: Restricted areas, TFRs, and special-use activations consistently rank near the top.
• Navigation system changes are constant: NAVAID status, ILS updates, and procedure amendments show steady operational churn.
• UAS activity keeps rising: Drone/UAS operations now appear in the top tier at many international FIRs.
• Winter operations are predictable: SNOWTAM peaks are highly seasonal and cluster around regional weather systems.

Top Airports and FIRs)

• Most active airport: KJFK leads with roughly 9.9% of the top‑20 share — a reflection of dense traffic, frequent construction cycles, and complex operations.
• Most active FIR: RJJJ (Japan FIR/ACC) follows closely at about 9.7%, indicating persistent airspace management activity and regular procedure/flow updates.
• Regional pattern: North American hubs (KJFK, KORD, KLAX, KEWR, KBOS, KATL, KCLT, KDFW) collectively contribute well over a third of the top‑20 share, while Eastern Europe and Central Asia FIRs (UUWV, ULLL, UWWW, UAAA) consistently appear in the top cohort — evidence of elevated restrictions and procedure churn.

Outlook: NOTAM volume keeps growing

We expect global NOTAM volume to keep climbing over the next 12–18 months. Across many FIRs we are observing more restriction‑related activity tied to military operations (TFRs, danger areas, airspace closures). See our field notes in the OSINT case study.

Key drivers we’re tracking:

• Military and geopolitical activity: increased TFRs, corridor shutdowns, and GPS/GNSS interference advisories — with elevated levels in parts of Eastern Europe, the Middle East, and the Western Pacific. We anticipate a 15–25% uplift in airspace‑restriction NOTAMs in directly affected FIRs.
• UAS/Drone proliferation: more local restrictions around stadiums, critical infrastructure and city centers. Expect UAS‑related NOTAMs to grow 20–35% year‑over‑year in busy TMAs.
• Space operations: launch and re‑entry windows are expanding hazard areas along coastal FIRs; cadence is trending upward.
• Infrastructure and capacity works: runway/taxiway rehabilitation cycles and lighting/NAVAID replacements will keep Aerodrome categories elevated.
• Procedure modernization (PBN/RNAV/GBAS): frequent chart and procedure updates drive steady increases in approach/departure NOTAMs.
• Climate and seasonal extremes: wildfires, volcanic ash and flooding produce episodic airspace closures and runway condition reporting beyond typical winter SNOWTAM peaks.
• Cyber/comm resilience: intermittent ATC communication/radar degradations and GNSS jamming reports surface as Communication and Navigation advisories.
• Major events: world sports, pilgrimages, summits and elections generate clustered, time‑boxed TFRs and flow‑control measures.

What to plan for:

• A higher baseline with sharper spikes around global events and winter seasons.
• A growing share of restriction‑type NOTAMs versus purely maintenance notices.
• Greater need for time‑aware filtering and category/effect toggles — precisely where Notamify’s interpretation, schedules and categories help.
• Use the Archive endpoint to baseline trends by airport/FIR, forecast staffing windows and validate operational playbooks.
