Graphical NOTAMs: from raw text to a cross on the map

What are graphical NOTAMs?

A graphical NOTAM is a NOTAM presented visually on a map or airport diagram instead of — or alongside — its raw text form. A NOTAM (Notice to Air Missions, formerly Notice to Airmen) is a time-critical notice alerting pilots to hazards or changes — such as a closed taxiway or runway — at an airport or along a route. In a graphical presentation, a closure that would otherwise be a line of all-caps abbreviations is drawn directly onto the airport surface, so a pilot can see at a glance which taxiway or runway is affected and where it sits relative to the planned route. TaxiwayClosed AI applies this idea with an AI agent: it reads the entire NOTAM package for an airport and places a clear cross (X) on the surface map exactly where a closure applies, making pre-flight NOTAM review faster and more convenient during flight preparation.

NOTAM visualization is not a fringe idea. The FAA, ICAO working groups, and major EFB vendors have all pushed toward more graphical NOTAM presentation in recent years, precisely because the text format has changed little since the era of teletype machines.

Why is raw NOTAM text so hard to read?

Raw NOTAMs are written in all capital letters, packed with contractions like TWY, BTN, and CLSD, and use compressed date-time groups that force a pilot to decode rather than simply read. Individually, each line is manageable. In practice, a pilot preparing a flight to a large hub may face dozens of NOTAMs covering everything from unlit obstacles to closed taxiways, all in the same undifferentiated wall of text — with no visual cue about which items actually touch the planned taxi route or runway.

The risk of important lines getting buried is well documented. In the widely cited July 2017 incident at San Francisco, an Air Canada crew lined up on a taxiway occupied by four airliners instead of the runway; the parallel runway was closed that night, and the NTSB noted that the closure NOTAM appeared on page 8 of a 27-page briefing package. The investigation highlighted, among other factors, how easily critical information can be lost inside dense NOTAM text — one of the reasons regulators and industry groups have since pressed for better NOTAM presentation, including graphical formats.

None of this means text NOTAMs are optional. They remain the official record, and pilots must still brief them via official sources such as the FAA NOTAM Search. Graphical NOTAMs are a comprehension layer on top — a faster way for the eye to find what matters, backed by our AI NOTAM parser that keeps the raw wording visible for comparison.

How does TaxiwayClosed AI turn NOTAMs into a graphical view?

Want to see the same approach applied to specific surfaces? The taxiway closure NOTAM map page walks through closure scenarios in depth, and the airport surface NOTAM app page covers the full review flow. Student pilots learning to decode NOTAMs from scratch can start with our student pilot NOTAM training guide.

Are graphical NOTAMs a replacement for official briefings?

No — and that boundary matters. Graphical NOTAMs, whether from an EFB vendor or from TaxiwayClosed AI, are an awareness layer that supports and streamlines flight preparation. The official NOTAM text remains authoritative, and mapping is only as good as the source data and the interpretation behind it. Use the cross on the map to orient yourself quickly, then verify every closure against official sources: your NOTAM briefing, current charts, approved EFBs, ATC, dispatch, and company procedures. TaxiwayClosed AI is not certified, not approved for navigation or operational decisions, and never claims to be — it simply makes the first read of a NOTAM package faster for pilots.
