This is step "1" of probably "many" in the process of separating out the scene management code and organizing it within simgear. My strategy is to identify the code I want to move, and break it's direct flightgear dependencies. Then it will be free to move over into the simgear package. - Moved some property specific code into simgear/props/ - Split out the condition code from fgfs/src/Main/fg_props and put it in it's own source file in simgear/props/ - Created a scene subdirectory for scenery, model, and material property related code. - Moved location.[ch]xx into simgear/scene/model/ - The location and condition code had dependencies on flightgear's global state (all the globals-> stuff, the flightgear property tree, etc.) SimGear code can't depend on it so that data has to be passed as parameters to the functions/methods/constructors. - This need to pass data as function parameters had a dramatic cascading effect throughout the FlightGear code.

/**
* Model an airspeed indicator tied to the pitot and static ports.
*
* Input properties:
*
Roy Vegard Ovesen: Instrumentation and systems are now configureable from xml files. The two generic configurations generic-systems.xml and generic-instrumentation.xml configures the systems and instrumentation as it was hardcoded. You can override the generic configurations in a similar way as you override the autopilot configuration.

* /instrumentation/"name"/serviceable
* "pitot_port"/total-pressure-inhg
* "static_port"/pressure-inhg
Simplify the pitot system and ASI -- the indicated airspeed should be more reasonable now.
