FlightGear Interface

The HLA interface enables the FlightGear flight simulator to participate an HLA 1.3 compliant simulation. Such simulation provides a virtual environment where all aircraft can interact.

This module should be compatible with any M&S HLA RTI (Run Time Infrastructure). It was tested with the ONERA CERTI HLA infrastructure.

The software is freely available under GPL via SourceForge.

User Instructions

Before using the FlightGear HLA interface, a HLA RTI must be started:


The FlightGear HLA interface can be enabled via the command line:

export CERTI_HOST=<rtig>
fgfs --callsign=[<callsign>] \


Address of a machine on which the RTIG is running.
Object name. Identification of this FlightGear. If not given, this FlightGear will not be visible to others (stealth mode).
Refresh rate [sec]. Determines how often this FlightGear should distribute updated information about own position.
Federate name. A unique identification of this FlightGear in the federation (simulation).
Federation name. Determines what federation this FlightGear should join.
Enables AviationSimNet conformance.
Enables RPR-FOM conformance. See SISO-STD-001.1-1999.
Federation object model (FOM). Determines a .fed file that describes the federation being joined. If not given, “.fed” is used by default.
