Stop bars Takeoff Hold Lights THL Follow the Greens FTG

Lit on the ground, the moment the controller sets them.

XPGuard shows controlled stop bars on the ground in MSFS 2020, MSFS 2024 and X-Plane 12 — automatically at every airport in the sim. When you're held short, the bar glows red. When you're cleared, the lights go off — right on the hold-short markings. Automatic Takeoff Hold Lights warn a lined-up crew when the runway ahead isn't safe for takeoff. And Follow the Greens lights your cleared taxi route with green centerline lights that lead you to the runway. One controller plugin drives every simulator. Completely free.

Airports tuned to the scenery you fly.

Stop bars and THL work at every airport by default, for both X-Plane and MSFS. Some sceneries place the holding positions differently from the real-world data, so those airports get a stop bar map of their own, thanks to the contributors — add-ons, and MSFS’s own built-in airports where they needed correcting too. Below is the list of handcrafted, moderator-reviewed maps. XPGuard matches the scenery you are using automatically — nothing to install.

Flying an add-on that isn't listed? Map it in the editor — it pairs with your simulator, and a moderator reviews it before it goes live.

How it works

From the scope to your taxiway.

Three steps, scope to ground. A controller sets it in EuroScope or vatSys, XPGuard syncs, and the lights appear on the ground in front of you — stop bars, automatic takeoff hold lights, and Follow-the-Greens taxi guidance.

STEP 01 · CONTROLLER

Set on the scope

A controller running an XPGuard plugin — EuroScope or vatSys — claims their runways and clicks the stop bars on the ground radar to set or clear them.

EuroScope · vatSys
STEP 02 · XPGUARD

Synced in real time

Every claim and click relays through XPGuard to every pilot connected at that airport, the same moment it happens.

Live network
STEP 03 · IN THE SIM

Lit on the ground

The XPGuard plugin draws stopbars exactly on the hold-short markings, lights takeoff hold lights down the runway ahead, and traces your cleared taxi route in moving green centerline lights — red to hold, off to roll, greens to follow.

What you get

Built to feel like the real ground.

Instant

No lag, no reload

Set or drop a bar and pilots see it the same moment. The ground stays in sync with the controller.

On the markings

Exactly where it belongs

Stop bars sit on the real hold-short positions, mapped straight onto the runways.

No FPS cost

Drawn the light way

Lights are drawn natively by the sim, so your frame rate doesn't notice they're there.

Every simulator

MSFS & X-Plane

One controller plugin drives MSFS 2020, MSFS 2024 and X-Plane 12 alike — stopbars derived automatically from each sim's airport data, at every airport.

Red or off

The real language

A lit red bar holds you short. Cleared, the lights go off. The same logic as the stop bars on a real taxiway.

Out of the box

No per-airport setup

Nothing to add or configure. The bars are already at every airport — contributors only fine-tune the rare ones that sit a little off.

Automatic

Takeoff hold lights

Lined up to depart? A double row of red centerline lights warns you when the runway ahead isn't clear, then goes dark once it is. Automatic — driven by the live traffic, not switched bar-by-bar.

Follow the Greens

Green taxi guidance

A controller draws your cleared taxi route in EuroScope; XPGuard lights it as green centerline lights that move with you and hold short of red bars — you taxi by following the greens, in MSFS and X-Plane alike. Available at airports with a published taxi network.

Two sides of the bar

For the pilot, and for the controller.

● For pilots

Hold short like the real world

Install the plugin, fly online, and watch stop bars light up wherever the controller is working.

  • Works in MSFS 2020, MSFS 2024 and X-Plane 12
  • Bars are already at every airport, out of the box
  • Automatic Takeoff Hold Lights warn you before an unsafe takeoff roll
  • Follow the Greens lights your cleared taxi route — taxi by following the greens
  • A control panel for settings and contribution
Get for X-Plane 12 Get for MSFS
● For controllers

Run the ground from EuroScope or vatSys

Load an XPGuard controller plugin — EuroScope or vatSys — claim the runways you're working, and click the stop bars to set or clear them. No scenery edits, no coordination needed.

  • Claim your runways
  • Click a bar to set it red; click again to clear it
  • Arm Takeoff Hold Lights per runway — XPGuard lights them from the live traffic
  • Guide pilots with Follow-the-Greens — draw the taxi route on the ground radar (EuroScope)
  • Pilots see it instantly across the network

Coverage — Stop bars & THL

Works at every airport. (Stop bars & THL)

XPGuard derives hold-short stop bars automatically from the sim's global airport database — every airport, in MSFS 2020, MSFS 2024 and X-Plane 12 alike, tens of thousands of airports. No adding airports, no per-airport setup; it just works everywhere, out of the box.

Follow the Greens

FTG capable airports.

Stop bars and Takeoff Hold Lights work everywhere. Follow the Greens needs a published taxi network for the airport — mapped by moderators & vACCs, per simulator and, where an add-on paints its taxiways differently, per publisher. These airports are ready today; the list grows as networks are published.

Contribution

Built by the people who fly it.

The stop bars are automatic, but a few sit a little off. XPGuard gets sharper when pilots and controllers fix the bars at their home airports. Here's how to pitch in.

Fix a bar

Fine-tune an airport

Sign in, open the airport by ICAO in the web map editor, nudge the auto-detected stop bars onto the right markings, and submit a correction — an admin reviews the diff and publishes.

Live preview

See it in the sim

Contribution mode shows your in-progress fixes on the ground in the sim, so you can check every bar before you submit.
