Detailed Description

Takes a set of initial conditions (IC) and provide a kinematically consistent set of body axis velocity components, euler angles, and altitude. This class does not attempt to trim the model i.e. the sim will most likely start in a very dynamic state (unless, of course, you have chosen your IC's wisely, or started on the ground) even after setting it up with this class.

Usage Notes

With a valid object of FGFDMExec and an aircraft model loaded:

   FGInitialCondition fgic=new FGInitialCondition(FDMExec);
   fgic->SetVcalibratedKtsIC()
   fgic->SetAltitudeAGLFtIC();

   // directly into Run
   FDMExec->GetState()->Initialize(fgic)
   delete fgic;
   FDMExec->Run()

   //or to loop the sim w/o integrating
   FDMExec->RunIC(fgic)

Speed

Since vc, ve, vt, and mach all represent speed, the remaining three are recalculated each time one of them is set (using the current altitude). The most recent speed set is remembered so that if and when altitude is reset, the last set speed is used to recalculate the remaining three. Setting any of the body components forces a recalculation of vt and vt then becomes the most recent speed set.

Alpha,Gamma, and Theta

This class assumes that it will be used to set up the sim for a steady, zero pitch rate condition. Since any two of those angles specifies the third gamma (flight path angle) is favored when setting alpha and theta and alpha is favored when setting gamma. i.e.

• set alpha : recalculate theta using gamma as currently set
• set theta : recalculate alpha using gamma as currently set
• set gamma : recalculate theta using alpha as currently set

The idea being that gamma is most interesting to pilots (since it is indicative of climb rate).

Setting climb rate is, for the purpose of this discussion, considered equivalent to setting gamma.

These are the items that can be set in an initialization file:

• ubody (velocity, ft/sec)
