Testing has two parts. First, BARS validates and previews the draft in the browser. Then the Pilot Client loads it into your simulator so you can inspect the real result.

​
Prepare the browser test

The editor carries its current draft into this page. You can also choose or drag an existing contribution XML file up to 5 MB.
1

Choose the contribution draft

Use the draft carried from the editor, select another XML file, or drag one into the upload area.
2

Select Prepare test

BARS checks the draft and prepares the preview.
3

Inspect the preview

Check every object on the map before opening the contribution in the simulator.

Prepare the draft, inspect its map preview, then open it in the Pilot Client.

​
Preview controls

Removal controls do not appear for X-Plane drafts. Check for:
  • Objects aligned with the intended taxiway, runway, and stand positions.
  • The correct BARS ID and light type at each location.
  • Complete lines with no accidental gaps or extra parts.
  • MSFS removal coverage over the default lights that BARS replaces.
If the preview is wrong, return to the editor, correct the draft, and prepare the test again.

​
Test in the simulator

1

Start the simulator

Load the supported simulator and spawn at the contribution airport.
2

Start the BARS Pilot Client

Confirm it is connected to the simulator before you continue.
3

Select Open in BARS Pilot Client

Allow the browser to open the Pilot Client if it asks. The Pilot Client enters Testing Mode and loads the prepared contribution.
4

Inspect every light

Testing Mode turns every submitted light on. Check position, spacing, direction, color, and duplicate default lighting from the cockpit and an external view.
5

Exit Testing Mode

Use the close action on the Pilot Client’s Testing Mode indicator when you finish.
If you open Testing Mode before the simulator is running at the correct airport, exit Testing Mode first. Load the airport, then start the test again from the website.
Read the Pilot Client Testing Mode guide for the browser prompt, client indicator, simulator view, and exit controls.

​
Continue to submission

Select Continue to submit only after the browser preview and in-simulator check are correct.

Submit the contribution

Add the final scenery details and send the tested draft for review.
