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 historical NOTAM context can support review and reporting.
• 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

The archive is designed for teams that need past NOTAM context without rebuilding it from scattered sources.

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• All cancelled and superseded NOTAMs (crucial for understanding changing conditions)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. Review Context

Historical records include the context needed for operational review, research, training, and audit work. Current field details are maintained in the public API documentation.

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
