ESJFS · RADAR
Bring Flight Simulator traffic into your ATC radar scope.
ESJFS (EuroScope JoinFS) is a flight-simulator ATC radar tool that displays simulator or JoinFS traffic on EuroScope, Aurora and VRC radar scopes.

Cross-platform. The current ESJFS V4+ release is written for .NET and can run on Windows, Linux and macOS. .NET 10 is required. Install .NET 10 from Microsoft before starting ESJFS.
Use with JoinFS
When ESJFS is used with JoinFS, a simulator does not need to be running. ESJFS can read the traffic from the whazzup file produced by JoinFS.
Read simulator traffic directly
ESJFS can read traffic directly from the simulator through SimConnect for FSX, P3D, MSFS and MSFS 2024, or through FSUIPC/XPUIPC for FS9 and X-Plane.
Requirements
- .NET 10 runtime.
- For JoinFS traffic: JoinFS and its whazzup output.
- For direct simulator traffic: the appropriate SimConnect, FSUIPC or XPUIPC interface.
- A compatible radar scope such as EuroScope, Aurora or VRC.
