Historical NOTAM Archives: Unlocking 2 Years of Aviation Intelligence

After requests from our enterprise customers, we're happy to announce our new Historical NOTAM Archives API endpoint – giving you access to a comprehensive 2-year NOTAM history.

Why Historical NOTAM Data Matters

Let's be clear – historical NOTAM data isn't just for record-keeping. It's a great source of operational intelligence that directly impacts your bottom line:

• Pattern Recognition: Notice that KJFK seems to have taxiway closures every September? Now you can verify that pattern with historical data and plan accordingly.
• Safety Analysis: When investigating an incident, having the exact NOTAMs active during the event provides crucial context that incident reports often miss.
• Training Enhancement: Show your pilots and dispatchers the actual NOTAM conditions from that challenging snowstorm last winter.
• Performance Optimization: Quantify how specific types of NOTAMs have historically impacted your operations – essential for true continuous improvement.

What You Get: Complete Historical Intelligence

Our historical archive isn't just a database dump. Each historical NOTAM comes with the full power of Notamify's intelligence suite:

1. 2-Year Archive

We've preserved everything from the past 24 months:

• Every NOTAM active on a given day
• All cancelled and superseded NOTAMs (crucial for understanding changing conditions)
• Global coverage across airports and FIRs

2. AI-Powered Interpretation

Your historical data is useless if you can't understand it. Each archived NOTAM includes:

• Plain-language interpretations that actually make sense
• Categorization across our 42 standardized categories for easy filtering
• Impact assessments so you can instantly spot the NOTAMs that truly mattered

3. Atomic Elements Integration

Break down historical NOTAMs into the components that matter for analysis:

• See exactly which runways were affected by what restrictions
• Track taxiway closures that might have caused ground delays
• Identify which approach procedures were unavailable during weather events
• Map precise airspace restriction boundaries for visualization

4. Enhanced Visualization Data

Make your historical data come alive:

• Plot NOTAM locations on maps with our parsed coordinate data
• Create precise timelines showing exactly when restrictions were active
• Understand relationships between connected NOTAMs that affected operations

Use Case for Historical NOTAM Data

Flight Delay and Cancellation Analysis

This might be the most requested use case from our airline customers. Historical NOTAMs provide the missing link in understanding operational disruptions:

• Root Cause Analysis: Determine which NOTAMs contributed to specific delay patterns
• Disruption Correlation: Match NOTAM types with cancellation rates to identify predictive factors
• Communication Improvement: Use historical patterns to better inform passengers about likely delay causes
• Recovery Planning: Analyze how past NOTAM situations affected recovery time, helping optimize future disruption responses
