The app
Airport surface NOTAM app for faster flight preparation
TaxiwayClosed AI is an airport surface NOTAM app for pilots: an AI agent reads the airport's NOTAM package for you, keeps the items that affect the surface, and marks every closed taxiway and runway with a cross on the airport diagram.
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 does an airport surface NOTAM app show pilots?
TaxiwayClosed AI is an airport surface NOTAM app built around the one question every pilot asks during flight preparation: what is closed on the ground today? You search an airport, and an AI agent ingests that airport's NOTAM package, filters out the items that do not affect the surface, and keeps the ones that do — taxiway closures, runway closures, and apron or movement-area restrictions. Each surface-relevant closure is then marked with a clear cross (X) directly on the airport diagram, exactly where the closed taxiway or runway segment lies. Instead of decoding dense NOTAM text line by line, a pilot gets a one-glance picture of the airport surface, with the original wording, effective dates, and an AI summary kept alongside each cross. It is an awareness and training aid: it speeds up NOTAM review, while official briefings and current charts always control.
First, the term itself. 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. A busy hub can publish dozens of them for a single day, and the two or three lines that actually change how you taxi are buried among lighting notes, crane advisories, and airspace items. Surfacing those few lines, visually, is the whole job of this app.
How does the AI agent read a NOTAM package?
The agent ingests the package
The AI agent reads the airport's full NOTAM package so you don't have to decode every abbreviation yourself.
Surface items are filtered
Taxiway, runway, and apron closures are kept; airspace, lighting, and unrelated items are set aside.
Crosses appear on the diagram
Each closure is matched to airport surface geometry and marked with a cross where the closed segment lies.
Under the hood this is the same parsing approach described on the AI NOTAM parser page: the agent extracts the subject (which taxiway or runway), the location qualifiers (between which intersections), the condition (closed), and the effective dates, then attaches a confidence and mapped status so you can see how certain the match is.
What does a real surface NOTAM look like? A worked LAX example
Here is a realistic taxiway closure NOTAM for Los Angeles International, in the compact format pilots see in a raw briefing package:
!LAX 07/085 LAX TWY C BTN TWY C8 AND TWY D CLSD 2607121500-2607192359
Decoded step by step:
| Element | Meaning |
|---|---|
| !LAX 07/085 | Accountability location and NOTAM number: the 85th NOTAM issued for LAX in July. |
| LAX | The affected airport — Los Angeles International. |
| TWY C | The subject: Taxiway Charlie. |
| BTN TWY C8 AND TWY D | The location: only the segment between Taxiway C8 and Taxiway D. |
| CLSD | The condition: closed. |
| 2607121500-2607192359 | Effective period in UTC: 12 July 2026 15:00 until 19 July 2026 23:59. |
TaxiwayClosed AI would read this line inside the LAX package, recognize it as a surface closure, and place a cross on Taxiway C between C8 and D on the LAX airport diagram — so the closure registers in one glance instead of six decoding steps. The taxiway closure map page shows more examples of how closures appear once they are drawn on the surface.
Who is a NOTAM app for pilots actually for?
General aviation pilots
Before a cross-country into an unfamiliar field, see at a glance whether your likely taxi routes or the runway you expect are affected by closures.
Airline crews
Skim the surface picture of the destination and alternates before the briefing, so the closure lines in the official package land on a mental map you already have.
Dispatchers and ops staff
Get quick visual context on how surface restrictions at a station could shape ground movement when reviewing the day's operation.
Student pilots and instructors
Practice reading real closure phrasing with the map as the answer key — see the student pilot NOTAM training guide.
Where does it fit in your flight preparation workflow?
The app works best as a first pass, before the official briefing — not instead of it. Open TaxiwayClosed AI while you plan, search your departure, destination, and alternates, and build the visual picture: which taxiways carry a cross, whether a runway is shortened or shut, and what the effective times are relative to your ETD and ETA. Then take your official briefing as normal. Because you already know where the crosses sit, the raw closure lines in the briefing read as confirmation rather than a wall of abbreviations, and anything the app missed or mismatched stands out immediately.
That order matters for safety, too. The app can be delayed, incomplete, or wrong, and a closure may fail to match a surface feature. Treat every cross as a prompt to check the source, not as clearance to plan around it. For real operations, retrieve the authoritative package from official sources such as FAA NOTAM Search, and follow your charts, approved EFB, ATC, dispatch, and company procedures.
Do you need an account or GPS to use it?
No. TaxiwayClosed AI has no registration, login, or profile system in the current version, and the privacy policy states it does not require GPS tracking or track live location for advertising or monitoring. You open the app, search an airport, and read the surface picture — nothing about your identity or position is part of that flow. That makes it easy to hand to a student, use on a personal device alongside company equipment, or try during flight preparation without any setup. Details on where the underlying NOTAM and map data come from — and where they can fall short — are on the data sources and limitations page.
