Both are designed and based on real-world Australian Air Traffic Control software. ## Types In the real world, INTAS is far more advanced and part of a complex comprehensive automation suite. In the BARS vatSys Plugin, INTAS has been replicated to include only the essential airport lighting management features. INTAS is a more advanced suite with additional features including windsock indications, lead-on light animations, and reactivation timers. Legacy is a far more simple system, which represents the design found in some older towers and contains the core airport lighting management features but excludes these additional elements.
