FGJSBsim Class Reference

#include <JSBSim.hxx>

Detailed Description

This class provides for an interface between FlightGear and its data structures and JSBSim and its data structures. This is the class which is used to command JSBSim when integrated with FlightGear. See the documentation for main for direction on running JSBSim apart from FlightGear.
