Initial revision
+Revision 1.3 2001/03/24 05:03:12 curt
+SG-ified logstream.

+Revision 1.2 2000/10/23 22:34:54 curt
+I tested:
+LaRCsim c172 on-ground and in-air starts, reset: all work
+UIUC Cessna172 on-ground and in-air starts work as expected, reset
+results in an aircraft that is upside down but does not crash FG. I
+don't know what it was like before, so it may well be no change.
+JSBSim c172 and X15 in-air starts work fine, resets now work (and are
+trimmed), on-ground starts do not -- the c172 ends up on its back. I
+suspect this is no worse than before.
+
+I did not test:
+Balloon (the weather code returns nan's for the atmosphere data --this
+is in the weather module and apparently is a linux only bug)
+ADA (don't know how)
+MagicCarpet (needs work yet)
+External (don't know how)
+
+known to be broken:
+LaRCsim c172 on-ground starts with a negative terrain altitude (this
+happens at KPAO when the scenery is not present). The FDM inits to
+about 50 feet AGL and the model falls to the ground. It does stay
+upright, however, and seems to be fine once it settles out, FWIW.
+
+To do:
+--implement set_Model on the bus
+--bring Christian's weather data into JSBSim
+-- add default method to bus for updating things like the sin and cos of
+latitude (for Balloon, MagicCarpet)
+-- lots of cleanup
+
+The files:
+src/FDM/flight.cxx
+src/FDM/flight.hxx
+-- all data members now declared protected instead of private.
+-- eliminated all but a small set of 'setters', no change to getters.
+-- that small set is declared virtual, the default implementation
+provided preserves the old behavior
+-- all of the vector data members are now initialized.
+-- added busdump() method -- SG_LOG's all the bus data when called,
+useful for diagnostics.
+
+src/FDM/ADA.cxx
+-- bus data members now directly assigned to
+
+src/FDM/Balloon.cxx
+-- bus data members now directly assigned to
+-- changed V_equiv_kts to V_calibrated_kts
+
+src/FDM/JSBSim.cxx
+src/FDM/JSBSim.hxx
+-- bus data members now directly assigned to
+-- implemented the FGInterface virtual setters with JSBSim specific
+logic
+-- changed the static FDMExec to a dynamic fdmex (needed so that the
+JSBSim object can be deleted when a model change is called for)
+-- implemented constructor and destructor, moved some of the logic
+formerly in init() to constructor
+-- added logic to bring up FGEngInterface objects and set the RPM and
+throttle values.
+
+src/FDM/LaRCsim.cxx
+src/FDM/LaRCsim.hxx
+-- bus data members now directly assigned to
+-- implemented the FGInterface virtual setters with LaRCsim specific
+logic, uses LaRCsimIC
+-- implemented constructor and destructor, moved some of the logic
+formerly in init() to constructor
+-- moved default inertias to here from fg_init.cxx
+-- eliminated the climb rate calculation. The equivalent, climb_rate =
+-1*vdown, is now in copy_from_LaRCsim().
+
+src/FDM/LaRCsimIC.cxx
+src/FDM/LaRCsimIC.hxx
+-- similar to FGInitialCondition, this class has all the logic needed to
+turn data like Vc and Mach into the more fundamental quantities LaRCsim
+needs to initialize.
+-- put it in src/FDM since it is a class
+
+src/FDM/MagicCarpet.cxx
+ -- bus data members now directly assigned to
+
+src/FDM/Makefile.am
+-- adds LaRCsimIC.hxx and cxx
+
+src/FDM/JSBSim/FGAtmosphere.h
+src/FDM/JSBSim/FGDefs.h
+src/FDM/JSBSim/FGInitialCondition.cpp
+src/FDM/JSBSim/FGInitialCondition.h
+src/FDM/JSBSim/JSBSim.cpp
+-- changes to accomodate the new bus
+
+src/FDM/LaRCsim/atmos_62.h
+src/FDM/LaRCsim/ls_geodesy.h
+-- surrounded prototypes with #ifdef __cplusplus ... #endif , functions
+here are needed in LaRCsimIC
+
+src/FDM/LaRCsim/c172_main.c
+src/FDM/LaRCsim/cherokee_aero.c
+src/FDM/LaRCsim/ls_aux.c
+src/FDM/LaRCsim/ls_constants.h
+src/FDM/LaRCsim/ls_geodesy.c
+src/FDM/LaRCsim/ls_geodesy.h
+src/FDM/LaRCsim/ls_step.c
+src/FDM/UIUCModel/uiuc_betaprobe.cpp
+-- changed PI to LS_PI, eliminates preprocessor naming conflict with
+weather module
+
+src/FDM/LaRCsim/ls_interface.c
+src/FDM/LaRCsim/ls_interface.h
+-- added function ls_set_model_dt()
+
+src/Main/bfi.cxx
+-- eliminated calls that set the NED speeds to body components. They
+are no longer needed and confuse the new bus.
+
+src/Main/fg_init.cxx
+-- eliminated calls that just brought the bus data up-to-date (e.g.
+set_sin_cos_latitude). or set default values. The bus now handles the
+defaults and updates itself when the setters are called (for LaRCsim and
+JSBSim). A default method for doing this needs to be added to the bus.
+-- added fgVelocityInit() to set the speed the user asked for. Both
+JSBSim and LaRCsim can now be initialized using any of:
+vc,mach, NED components, UVW components.
+
+src/Main/main.cxx
+--eliminated call to fgFDMSetGroundElevation, this data is now 'pulled'
+onto the bus every update()
+
+src/Main/options.cxx
+src/Main/options.hxx
+-- added enum to keep track of the speed requested by the user
+-- eliminated calls to set NED velocity properties to body speeds, they
+are no longer needed.
+-- added options for the NED components.
+
+src/Network/garmin.cxx
+src/Network/nmea.cxx
+--eliminated calls that just brought the bus data up-to-date (e.g.
+set_sin_cos_latitude). The bus now updates itself when the setters are
+called (for LaRCsim and JSBSim). A default method for doing this needs
+to be added to the bus.
+-- changed set_V_equiv_kts to set_V_calibrated_kts. set_V_equiv_kts no
+longer exists ( get_V_equiv_kts still does, though)
+
+src/WeatherCM/FGLocalWeatherDatabase.cpp
+-- commented out the code to put the weather data on the bus, a
+different scheme for this is needed.
