and "isOnRunway". - Added initial support for AI controlled pushback operations, making use of the current editing capabilities of TaxiDraw CVS / New_GUI_CODE. The current implementation is slightly more computationally intensive than strictly required, due to the currently inability of taxidraw to link one specific pushBack point to to a particular startup location. FlightGear now determines this dynamically, and once we have that functionality in TaxiDraw, the initialization part of createPushBack() can be further simplified. - Smoother transition from pushback to taxi. No more skipping of waypoints, and aircraft wait for two minutes at pushback point. - The classes FGTaxiNode, FGTaxiSegment, and FGParking, now have copy constructors, and assignment operators. - Removed declaration of undefined constructor FGTaxiNode(double, double, int) - Array boundry checks and cleanup. - Modified Dijkstra path search algoritm to solve partial problems. Currently limited to include pushback points and routes only, but can probably be extended to a more general approach. - Added initial support for giving certain routes in the network a penalty, in order to discourage the use of certain routes over others.
