begins with the IC values from the given FGInitialCondition

When an aircraft model is loaded the config file is parsed and for each of the
sections of the config file (propulsion, flight control, etc.) the
- corresponding "ReadXXX()" method is called. From within this method the
- "Load()" method of that system is called (e.g. LoadFCS).
