VATSIM (Virtual Air Traffic Simulation Network)

VATSIM (Virtual Air Traffic Simulation Network) is the world's largest and most established free network for flight simulation, connecting pilots and virtual Air Traffic Controllers in a single, shared global environment. It allows simmers using MSFS, X-Plane, or Prepar3D to fly with live, human ATC, providing the highest level of realism and immersion available.

The network is built on the motto "Aviate, Educate, Communicate," placing a massive emphasis on being a learning environment. While it can be intimidating for newcomers, VATSIM provides a comprehensive "Pilot Academy" and a progressive rating system to guide new users. It's designed to teach real-world procedures, from filing your first VFR flight plan to navigating complex IFR arrivals and oceanic crossings.

The entire network is 100% free and is operated by a global, non-profit community of volunteers. For any simmer looking to move beyond AI traffic and truly simulate real-world operations, VATSIM is the ultimate destination.
