The AI agent ingests the airport's entire NOTAM package — every notice, not a filtered subset — so no closure is skipped.
NOTAM map
NOTAM map: every taxiway closure marked with a cross
TaxiwayClosed AI is an AI agent that reads the entire NOTAM package for pilots and draws a clear cross on the airport diagram exactly where a taxiway or runway is closed — a NOTAM map you can scan in seconds during flight preparation.
Awareness and training aid only. Always verify with official NOTAM briefings, current charts, approved EFBs, ATC, dispatch, and company procedures before any real operation.
What is a NOTAM map?
A NOTAM map is an airport diagram on which the information inside NOTAMs is drawn at the exact spot it affects, instead of being left as coded text. 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. TaxiwayClosed AI builds this map automatically: an AI agent reads the entire NOTAM package for an airport, identifies every taxiway and runway closure, and places a clear cross (X) directly on the affected segment of the airport surface map. One glance at the diagram shows a pilot what is closed and where. It is an awareness and training aid that streamlines pre-flight NOTAM review — pilots must still verify with official briefings, current charts, approved EFBs, ATC, and dispatch before any real operation.
Why is a text NOTAM hard to place on the airport surface?
A closure NOTAM is written for machines and teleprinters, not for a pilot's mental picture of an airport. It names surfaces by designator, bounds them by intersections, and compresses everything into abbreviations: TWY, BTN, AD, CLSD, WIP. To place one line of text spatially, a pilot has to hold the airport diagram in mind, find the taxiway, find both intersections that bound the closed portion, and picture the segment in between — then repeat that for every closure NOTAM in the package. At a large hub, a briefing can contain dozens of surface NOTAMs referencing taxiways the pilot has never used.
That mental mapping is exactly the step where details get lost. Reading "TWY B BTN TWY A AND TWY C CLSD" is easy; remembering where that segment sits while taxiing out of a busy apron is not. A NOTAM map removes the translation step: the closure is already drawn where it belongs, so flight preparation starts from the picture instead of ending with it.
How does the AI agent turn NOTAM text into a cross on the map?
Extract each closure
It decodes the NOTAM text: which surface, which segment, between which intersections, and for which dates and times. The AI NOTAM parser handles the abbreviations.
Match the geometry
Each closure is matched to the corresponding taxiway or runway segment in the airport surface geometry used by the airport surface NOTAM app.
Draw the cross
A cross (X) is drawn on that exact segment of the airport diagram, with the raw NOTAM text and AI summary one tap away.
A worked example: an ORD taxiway closure on the NOTAM map
Here is a realistic taxiway closure NOTAM for Chicago O'Hare International (ORD):
!ORD 07/052 ORD TWY B BTN TWY A AND TWY C CLSD 2607151200-2607252359
Decoded step by step:
| Element | Meaning |
|---|---|
| !ORD 07/052 | NOTAM issued for Chicago O'Hare, the 52nd of July 2026 |
| ORD TWY B | Subject: Taxiway B at O'Hare |
| BTN TWY A AND TWY C | Only the portion between the intersections with Taxiway A and Taxiway C |
| CLSD | Condition: closed |
| 2607151200-2607252359 | From 15 July 2026 12:00 UTC until 25 July 2026 23:59 UTC |
On the NOTAM map, TaxiwayClosed AI places the cross on Taxiway B precisely on the stretch bounded by its intersections with Taxiway A and Taxiway C — not at the start of B, not across all of B. The rest of Taxiway B stays drawn normally, because it remains usable. A pilot preparing a flight into ORD sees instantly that a mid-segment of B is out, and can think about how a taxi route from the ramp might be affected before ever reading the raw text.
What do the cross, confidence, and mapped status mean?
The cross (X)
A cross on a taxiway or runway segment means the AI agent read a NOTAM closing that surface for a stated period. Tap it to see the original NOTAM text and its plain-language summary.
Confidence
Confidence indicates how clearly the NOTAM wording matched a specific surface segment. High confidence means an unambiguous match; lower confidence means the wording left room for interpretation.
Mapped status
Mapped means the closure was placed on the diagram. Unmapped items are still listed with their raw text, so a closure is never silently dropped just because it could not be drawn.
Raw text always available
The original NOTAM stays one tap away from every cross, so pilots can compare the map against the source wording — and against official sources.
How do pilots use a NOTAM map during flight preparation?
Most pilots use the NOTAM map as a first pass and a final cross-check. Before the official briefing, a glance at the departure and destination diagrams shows which taxiways and runways carry crosses, so the dense text in the briefing already has spatial context. After the briefing, the map is a quick way to confirm nothing was misread — if a closure in the official package has no cross, or a cross has no matching line in the briefing, that difference is worth resolving before engine start. Student pilots also use it to practice decoding, as covered in our NOTAM training guide for student pilots.
The official sources always control. Retrieve current NOTAMs from official sources such as the FAA NOTAM Search, and follow the NOTAM guidance in the FAA Aeronautical Information Manual. TaxiwayClosed AI makes NOTAM review faster and more convenient; it never replaces the briefing itself.
Frequently asked questions
Is a NOTAM map an official briefing source?
No. TaxiwayClosed AI is an awareness and training aid for pilots. Always verify with official NOTAM briefings, current charts, approved EFBs, ATC, dispatch, and company procedures before any real operation.
Does the NOTAM map show runway closures as well as taxiway closures?
Yes. The AI agent reads the whole NOTAM package and places a cross on closed taxiways and closed runways alike, so the airport diagram reflects surface closures in one view.
What happens when a closure NOTAM cannot be placed on the map?
The item is shown as unmapped with its raw NOTAM text and AI summary, so pilots know a closure exists even when the exact segment could not be matched to the airport surface geometry.
