SKAI Traffic v2.3 is a unified AI aircraft and flight plan package designed to operate across Microsoft Flight Simulator 2004 (FS9) and Flight Simulator X (FSX).
The primary goal: replace default AI traffic with realistic airline schedules, accurate aircraft models, liveries, and airport parking definitions.

SKAI Traffic (often stylized as "SKAI Traffic" or "SKAI AI Traffic") is a freeware AI traffic package developed by the now-defunct SKAI team. Unlike payware giants like Ultimate Traffic or MyTraffic, SKAI was a community-driven project focused on high-quality models, realistic textures, and accurate flight schedules—all at zero cost.

Version 2.3 represents the final, most polished release of the SKAI project. It includes:
The "v2.3" designation is critical. Earlier versions (v1.0, v2.0) had model alignment issues and missing textures. Version 2.3 fixed the notorious "black aircraft" bug and introduced native FSX DX10 preview support. SKAI Traffic v2
| Simulator | Average FPS loss | RAM usage increase | |-----------|------------------|--------------------| | FS9 | −5 to −10 fps | +150 MB | | FSX | −10 to −18 fps | +250 MB |
Optimization mode (lower LOD, reduced ground traffic) recommended for FSX. Important: Delete any old Traffic_*
The only downside of v2.3 is its 2008–2010 era flight schedules. Fortunately, the community has kept it alive:
To install a new livery:
| Problem | Solution |
|---------|----------|
| "Black AI aircraft" | You missed the FSX hotfix textures. Re-apply the Texture folder from the hotfix. |
| No traffic at airports | Check that Traffic_SKAI.bgl is in the correct Scenery folder. Also ensure your FS date is not in the past (SKAI schedules start 2010). |
| FSX crashes on loading | You likely ran out of memory. Reduce AI density to 50% and install the UIAutomationCore.dll fix (common for FSX under Windows 10/11). |
| Missing sounds | SKAI uses default FS sounds. No separate sound pack is needed. |
